private void Form1_Load(object sender, EventArgs e)
{
AutoCompleteStringCollection nc = new AutoCompleteStringCollection();
nc.AddRange(new string[]
{
"boston",
"sanfransisco"
});
textBox1.AutoCompleteCustomSource = nc;
textBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
textBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;
}
Autocomplete isn't working and I don't know why. If I add more strings to the array they still don't show up and I've tried moving new AutoCompleteStringCollection() out of the private method. I have the properties set the same way in the form properties too.
Do you have to import something for AutoCompleteMode to work?
From the documentation on AutoCompleteSource you can find this note
AutoCompleteSource does not work on multiline TextBox controls.
So you could only switch to a MultiLine=false to have your code to work.
Searching on the NET there are various solutions that give to a multiline textbox the functionality of AutoComplete, but they always include some tweaking on the PreviewKeyDown method

I'm trying to prevent a CollapsingToolbar from expanding for one of my fragments.
Currently, when I use the method setExpanded(), I am able to see the toolbar in its collapsed state.
appBarLayout.setExpanded(false, true);
However, the collapsingToolbar is still expandable, which is not what I want. I want the collapsingToolbar to not be expandable for this particular fragment.
In other words, I want the collapsingToolbar to behave and look like a regular toolbar (i.e. "not expandable") for this particular fragment only.
I am using Mike Penz's Material Drawer. The code below shows the relevant code, with notes indicating what I have tried.
private void buildDrawer(){
Drawer drawer = new DrawerBuilder()
.withActivity(this)
.withFullscreen(true)
.withTranslucentStatusBar(true)
.withToolbar(toolbar)
.withAccountHeader(accountHeader)
.addDrawerItems(
item1,
item2,
new DividerDrawerItem(),
item3,
item4
)
.withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
#Override
public boolean onItemClick(View view, int position, IDrawerItem drawerItem) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
Fragment f = new Fragment();
switch (position) {
//other cases not shown
case 2:
f = new LocateFragment();
appBarLayout.setExpanded(false, true);
//Adding the following three lines don't work - causes the toolbar to be unscrollable, but in its expanded form
//AppBarLayout.LayoutParams p = (AppBarLayout.LayoutParams)collapsingToolbarLayout.getLayoutParams();
//p.setScrollFlags(AppBarLayout.LayoutParams.SCROLL_FLAG_SNAP);
//collapsingToolbarLayout.setLayoutParams(p);
//toolbar.setCollapsible(false); doesn't work either
collapsingToolbarLayout.setTitle("Locate Events");
setInvisibleAddPhotoFab();
break;
//other cases not shown
}
fragmentTransaction.replace(R.id.frame_fragments, f);
fragmentTransaction.commit();
return false; //close drawer onclick
}
})
.build();
loadBackdrop();
}
This is what I want - I want the toolbar to be unexpandable:
Currently, however, it is still expandable, so the image below is NOT what I want:
UPDATE:
I was able to collapse the toolbar and prevent it from expanding like so (code below), but I've run into another issue - the title no longer appears on the collapsingToolbar when I set it like so: collapsingToolbarLayout.setTitle("string");
appBarLayout.setExpanded(false, true);
int px = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 80, getResources().getDisplayMetrics());
CoordinatorLayout.LayoutParams lp = (CoordinatorLayout.LayoutParams)appBarLayout.getLayoutParams();
lp.height = px;
appBarLayout.setLayoutParams(lp);
I was able to resolve this problem using the following (as shown here by #DanielPersson):
collapsingToolbarLayout.setTitleEnabled(false);
toolbar.setTitle(title);
I have created a Form using c++ (CLR).
I have added a richtextbox and I need to make it visible in my source file in order to change the text from there.
So to sum it up:
I have a richtextbox in MyForm.h.I need to change the text of this richtextbox from Source.cpp.How do I do that?
Managed to fix it by doing so:
Creating a new function in the .cpp source file like this:
void TEST(System::Windows::Forms::RichTextBox ^ changin)
{
changin->Text = "TEST";
}
Than in the .h file
void TEST(System::Windows::Forms::RichTextBox ^ changin);
Here is when a button is pushed:
private: System::Void button4_Click(System::Object^ sender, System::EventArgs^ e) {
TEST(richTextBox4);
}
Where richTextBox4 is the one that should be modified from the .cpp file.
Pass your text through a public function in your form and there update the text.
In such way you save object encapsulation.
In your form add a method in the following manner:
In the form you have a private field:
private RichTextBox rtb;
rtb is reference to a user control containing the RichTextBox which expose the RichTextBox text property by overriding it:
public override string Text
{
get
{
return rtb.Text;
}
set
{
rtb.Text = value;
}
}
then by a public method in your form you can access the RichTextBox.
public void SetText()
{
rtb.Text = "test_text";
}
you can have a look on the same idea here:
http://www.codeproject.com/Articles/18178/A-Padded-Text-Box-Control
Update : have a look on the following example it emphasize my explanation above : http://www.codeproject.com/Articles/4544/Insert-Plain-Text-and-Images-into-RichTextBox-at-R
I hope it is clear enough.
I have 2 Telerik's rad grids. First one is master and second one is detail. I can delete rows from both grids independently by pressing "Delete" button on toolbar above each grid. I also have "Refresh" buttons in toolbar of both grids.
The problem is with detail grid. When I delete item(s) the grid doesn't refresh. Calling Rebind method doesn't help. The only thing that helps is to press "Refresh" button in toolbar of master grid and select the row in master grid by mouse that was previously selected. After that I can see refreshed detail grid.
So, I don't need to press "Refresh" button in toolbar of master grid and select the row in master grid by mouse. I can refresh the master grid programmatically and only want to reselect the item that was originally selected also programmatically. I've tried this:
item.Selected = true;
But, it only visually selects the item in master grid and doesn't refresh the detail grid.
So, how to select the item in master grid programmatically in order to get the same effect as selecting it by mouse?
Thank you in advance.
I've just realised that your probably using different DataSource for both grids, but pointing to the same database, right? My example below uses the same datasource for both grids. However I made on a detail view versus a normal view by making some columns not visible. Maybe this strategy could fix your issue?
My first thought was to try implement the SelectionChanged event, or if not that, the SelectionChanging event. Put a refresh in there you see. But I didn't end up doing it that way.
I wrote a small program as below. It saves the edits to disk with any row change as long as its not a remove (I had trouble saving remove edits when the button was clicked it gave a null pointer exception on the remove command). It also saves changes just before closing the program (so that any delete rows are also saved then). I did find that the deleteOne and deleteTwo buttons (that delete from the first or second grid, respectively) do in fact cause the deletion to occur in both grids. So a possibility is you could use the radGridView1.Rows.Remove(row) or RemoveAt(i) command if that works in your situation?
Another possibility is that if refresh isn't working you could set the DataSource to null and then set it to the data source again, after deleting the row. This is a bit drastic but if it's the only thing that works? I'm talking about the data source for both grids.

I am working on an Excel 2010 template project. In my template I have many sheets with static ListObject controls in each of them. To initialize my ListObject, I bind a BindingList<MyCustomType> so it generates a column for each of my MyCustomType public properties. It is really handy because when the user some rows in the ListObject, it automatically fills up my BindingList instance. I added a button in the Excel ribbon so that the program can validate and commit these rows through an EDM. This is how I bind my data to the ListObject in the startup event handler of one of my Excel sheet.
public partial class MyCustomTypesSheet
{
private BindingList<MyCustomType> myCustomTypes;
private void OnStartup(object sender, System.EventArgs e)
{
ExcelTools.ListObject myCustomTypeTable = this.MyCustomTypeData;
BindingList<MyCustomType> customTypes = new BindingList<MyCustomType>();
myCustomTypeTable.SetDataBinding(customTypes);
}
// Implementation detail...
}
Now my issue is that it is very likely that the user of this template will enter these rows in many sessions. It means that he will enter data, save the file, close it, reopen it, enter some new rows and eventually try to commit these rows when he thinks he is done. What I noticed is that when the Excel file created from the template is reopened, the DataSource property of my ListObject controls is null. Which means I have no way to get back the data from the ListObject into a BindingList<MyCustomType>. I have been searching and I found no automatic way to do that and I don't really want to make a piece of code that would crawl through all of the columns to recreate my MyCustomType instances. In an ideal world I would have done like this.
private void OnStartup(object sender, System.EventArgs e)
{
ExcelTools.ListObject myCustomTypeTable = this.MyCustomTypeData;
BindingList<MyCustomType> customTypes = null;
if (myCustomTypeTable.DataSource == null) // Will always be null and erase previous data.
{
customTypes = new BindingList<MyCustomType>();
myCustomTypeTable.SetDataBinding(customTypes);
}
else
{
customTypes = myCustomTypeTable.DataSource as BindingList<MyCustomType>;
}
}
I have been doing a lot of research on this but I was not able to find a solution so I hope some of your can help me to resolve this issue.
Thanks.
As a last solution I decided that I would serialize my object list in XML and then add it as a XML custom part to my Excel file on save. But when I got into MSDN documentation to achieve this, I found out that there was 2 ways to persist data: XML custom part and data caching. And actually data caching was exactly the functionality I was looking for.
So I have been able to achieve my goal by simply using the CachedAttribute.
public partial class MyCustomTypesSheet
{
[Cached]
public BindingList<MyCustomType> MyCustomTypesDataSource { get; set; }
private void OnStartup(object sender, System.EventArgs e)
{
ExcelTools.ListObject myCustomTypeTable = this.MyCustomTypeData;
if (this.MyCustomTypesDataSource == null)
{
this.MyCustomTypesDataSource = new BindingList<MyCustomType>();
this.MyCustomTypesDataSource.Add(new MyCustomType());
}
myCustomTypeTable.SetDataBinding(this.MyCustomTypesDataSource);
}
private void InternalStartup()
{
this.Startup += new System.EventHandler(OnStartup);
}
}
It works like a charm. You can find more information about data caching in MSDN documentation.
I developed an outlook add in (custom task pane), with web browser in the user control.
All the things working well beside the backspace or the delete button when I am writing something in text box in the web browser, I can't use those keys, am I missing something?
I am a few years late to the party but I managed to fix this. The easiest way to fix this is to ensure proper focus is given to the input fields, so you will need to be able to run your own javascript on whatever page is being loaded.
The javascript I run on the page is as follows (using jQuery):
$(document).on("click", function (e) {
// first let the add-in give focus to our CustomTaskPane
window.external.focus();
// then in our web browser give focus to whatever element was clicked on
$(e.target).focus();
});
the window.external variable contains code run from the plugin (c# or VB I assume) which is exposed so we can interact from web page back to the add-in.
In the add-in code for the custom taskpane set the context of window.external:
// event when webBrowser is finished loading document
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
// sets context of window.external to functions defined on this context
webBrowser1.ObjectForScripting = this;
}
And a public method for focusing:
// can be called by the web browser as window.external.focus()
public void focus()
{
this.Focus();
}
This worked for me, and I hope it helps others. Although do note that this probably doesn't work if the user keyboard navigates using tab, but you can either extend this code for that use case, or safely assume that the average outlook user will have his hand glued to the mouse.
Ok I solved the problem ,
The problem is that the custom task pane in not always gets fucos from the outlook.
So, I raised an event every time that there is "onclick" for all the pane, and then forced the pane to be in focus.
spent a lot of time trying to get this working in Outlook v16.0.13801.20288 the above did not work for me. I ended up with this working code.
Create a user control and add your webbrowser control to it then customize the .cs as below
private void CreateTaskPane() {
MyWinFormUserControl webBrowser = new MyWinFormUserControl();
webBrowser.webBrowser3.Url = new Uri("https://google.com");
webBrowser.webBrowser3.Width = 500;
webBrowser.webBrowser3.Dock = DockStyle.Fill;
webBrowser.webBrowser3.Visible = true;
webBrowser.Width = 500;
webBrowser.Dock = DockStyle.Fill;
webBrowser.Visible = true;
this.CRMTaskPaneControl = CustomTaskPanes.Add(webBrowser, "My App");
//Components.WebViewContainerWPFUserControl webView = (Components.WebViewContainerWPFUserControl)_eh.Child;
//webView.webview.Source = new Uri("https://localhost:3000");
this.CRMTaskPaneControl.Width = 500;
System.Windows.Forms.Application.DoEvents();
this.CRMTaskPaneControl.Control.Focus();
this.CRMTaskPane.Visible = true;
}
public partial class MyWinFormUserControl : UserControl
{
public WebBrowser webBrowser3;
public System.Windows.Forms.WebBrowser webBrowser1;
public MyWinFormUserControl()
{
InitializeComponent();
}
private void InitializeComponent()
{
this.webBrowser3 = new System.Windows.Forms.WebBrowser();
this.SuspendLayout();
//
// webBrowser3
//
this.webBrowser3.Dock = System.Windows.Forms.DockStyle.Fill;
this.webBrowser3.Location = new System.Drawing.Point(0, 0);
this.webBrowser3.MinimumSize = new System.Drawing.Size(20, 20);
this.webBrowser3.Name = "webBrowser3";
this.webBrowser3.Size = new System.Drawing.Size(500, 749);
this.webBrowser3.TabIndex = 0;
this.webBrowser3.DocumentCompleted += new System.Windows.Forms.WebBrowserDocumentCompletedEventHandler(this.webBrowser3_DocumentCompleted);
//
// MyWinFormUserControl
//
this.Controls.Add(this.webBrowser3);
this.Name = "MyWinFormUserControl";
this.Size = new System.Drawing.Size(500, 749);
this.Load += new System.EventHandler(this.MyWinFormUserControl_Load);
this.ResumeLayout(false);
}
void webBrowser3_DocumentCompleted(object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs e)
{
HtmlDocument doc;
doc = webBrowser3.Document;
doc.Click += doc_Click;
}
void doc_Click(object sender, HtmlElementEventArgs e)
{
this.Focus(); // force user control to have the focus
HtmlElement elem = webBrowser3.Document.GetElementFromPoint(e.ClientMousePosition);
elem.Focus(); // then let the clicked control to have focus
}
private void MyWinFormUserControl_Load(object sender, EventArgs e)
{
//Control loaded
}
Turns out this is an easy issue to fix.
Just write
class MyBrowser : WebBrowser {}
Then use MyBrowser instead of the .NET one.
