Deselect text in a textbox - c#-4.0

I have a windows form that sets the text property in a textbox to that of a string variable. When the form is ran, it has all of the text in the textbox selected. I need to try and figure out how to keep that from happening. I tried the
DeslectAll()
method on the textbox but that doesn't seem to work. I also tried
txtBox.SelectNextControl(txtCostSummary, true, false, true, true);
but I kind of was guessing on what the paramters needed to be set to, tweaking them doesn't seem to make a difference. To really understand what I'm doing I'll make it a little more clear on how this all is happening.
public Form1()
{
Apple a = new Apple();
a.IwantThisText = "Item 1: " + 50.00 + "\r\n";
txtBox.Text = a.IwantThisText;
}
Class Apple
{
private string iWantThisText;
public string IwantThisText
{
get { return iWantThisText; }
set { iWantThisText += value; } // Appends what was there before
}
}
Everything works fine except the part where it has printed the information in the textbox but all the text in the textbox is selected, which isn't what I thought would happen, nor is it what I want to happen.
Thanks for any ideas!

Try this:
txtBox.Select(0, 0);

I know it's an old question, but I found that this works too:
txtBox.SelectionLength = 0;
This might be preferable to #SteveCav's Select(0,0) as it doesn't move the selection start point.

Try this:
//remove focus from control.
Apple a = new Apple();
a.IwantThisText = "Item 1: " + 50.00 + "\r\n";
txtBox.Text = a.IwantThisText;
// Add this
txtBox.TabStop = false;

Dialog RunBase custom lookup: Alt + Down key combination doesn't work

MS Dynamics AX 4.0
I have a class with a dialog that extends RunBase, a dialogField of Range type and a custom lookup for it. It works as planned but one thing upsets me.
Normal lookup opens on Alt + Down key combination, but it doesn't work in my dialog. I assume this is because "Range" EDT is not related to any TableField.
But I have my own lookup, can I force it somehow to drop down on Alt + Down?
Here is my dialog method:
protected Object dialog(DialogRunBase dialog, boolean forceOnClient)
{
Object ret;
;
ret = super(dialog, forceOnClient);
dialogFld = new DialogField(ret, typeid(Range), 100);
dialogFld.init(ret);
dialogFld.lookupButton(FormLookupButton::Always);
dialogFld.fieldControl().replaceOnLookup(false);
return ret;
}
Here is my lookup, as you can see, it's based on ItemId EDT:
protected void Fld100_1_Lookup()
{
TableLookup_RU sysTableLookup = new TableLookup_RU();
Query query = new Query();
FormRun lookupForm;
QueryBuildDataSource qbds = query.addDataSource(tablenum(InventTable));
;
sysTableLookup.parmTableId(tablenum(InventTable));
sysTableLookup.parmCallingControl(dialogFld.fieldControl());
sysTableLookup.addLookupfield(fieldnum(InventTable, ItemId));
sysTableLookup.addLookupfield(fieldnum(InventTable, ItemName));
findOrCreateRange_W(qbds, fieldnum(InventTable, ItemType), SysQuery::valueNot(ItemType::Service));
sysTableLookup.parmQuery(query);
lookupForm = sysTableLookup.formRun();
dialogFld.fieldControl().performFormLookup(lookupForm);
}
And dialogPostRun:
public void dialogPostRun(DialogRunbase dialog)
{
;
dialog.formRun().controlMethodOverload(true);
dialog.formRun().controlMethodOverloadObject(this);
super(dialog);
}
This problem is not that critical, but it bothers me. If someone could help, I'd be really grateful.
P.S.: I could use ItemId typeId, but I need to append many items, and ItemId is only 20 chars long..
I've discovered that I don't have to use Range typeid for the dialogField. dialogField.limitText(int) works just fine, it overrides the length of EDT. So I changed dialog method like this:
protected Object dialog(DialogRunBase dialog, boolean forceOnClient)
{
Object ret;
;
ret = super(dialog, forceOnClient);
dialogFld = new DialogField(ret, typeid(ItemId), 100); //if typeId doesn't have relations Alt + Down doesn't work
dialogFld.init(ret);
dialogFld.label("#SYS72708");
dialogFld.lookupButton(FormLookupButton::Always);
dialogFld.limitText(200);
dialogFld.fieldControl().replaceOnLookup(false);
return ret;
}
Create a new extended data type ItemIdRange, extend from Range.
Be sure to set the relation on the new type to relate to InventTable.ItemId to get automatic lookup.
Also the form control must have property ReplaceOnLookup set to no, to allow the user to add more criteria. For a DialogRunbase field this may be done this way:
FormStringControl fsc = dialogField.control();
fsc.replaceOnLookup(false);
The code posted in the question is then not needed.

How to use ABPeoplePickerNavigationController in MonoTouch to pick a specific email address or phone number of a contact?

I have been using the ABPeoplePickerNavigationController in a project, written in MonoTouch, to pick a specific email address or phone number of a contact.
The code set a delegate, and in the delegate I implemented the ShouldContinue method, and retrieved the contact using the Handle property of all contacts. Unfortunately, it looks like something changed, or that I used undocumented features, or that I was simply lucky, because now when I'm in the process of updating the app for iPhone 5, the code no longer works.
Edit: Ok, my initial thoughts was that this was caused by changes in MonoTouch, since there has been quite a few updates since I last worked on this app. However, I now removed it from my device and downloaded the version I have on the app store, and it crashes in the same manner, null reference exception.
This means it is an iOS upgrade that made my code non-functional.
The goal of my code:
Pick a person's specific email address, not just the person, but navigating into the details of the person, and selecting a specific email address or telephone number.
The below code deals with phone numbers only, the email code looks 95% similar.
Here is the code that constructs the picker:
var picker = new ABPeoplePickerNavigationController();
picker.Init();
picker.DisplayedProperties.Clear();
picker.DisplayedProperties.Add(ABPersonProperty.FirstName);
picker.DisplayedProperties.Add(ABPersonProperty.Phone);
var del = new PhonePickerDelegate();
picker.Delegate = del;
Here is the delegate class:
private class PhonePickerDelegate : ABPeoplePickerNavigationControllerDelegate
{
public override bool ShouldContinue(ABPeoplePickerNavigationController peoplePicker, IntPtr selectedPerson, int propertyId, int identifier)
{
peoplePicker.DismissModalViewControllerAnimated(true);
// THE NEXT LINE IS THE ONE THAT NO LONGER WORKS
var contact = peoplePicker.AddressBook.SingleOrDefault(s => s.Handle == selectedPerson) as ABPerson;
using (var phones = contact.GetPhones())
{
int index = phones.GetIndexForIdentifier(identifier);
var phone = phones.GetValues()[index];
var name = (contact.FirstName + " " + contact.MiddleName).Trim() + " " + contact.LastName;
Selected(name + ": " + phone);
}
return false;
}
public override void Cancelled(ABPeoplePickerNavigationController peoplePicker)
{
peoplePicker.DismissModalViewControllerAnimated(true);
}
}
Unfortunately this code no longer finds the correct contact, as none of the contacts has a Handle value that corresponds to the selectedPerson IntPtr value.
My questions are these:
How can I fix the above code?
Can I fix the above code?
Is there some other class/method/delegate/event or whatnot I should be using instead?
You could do something like the following:
Note that AppDelegate.navigation would be your current NavigationController
using MonoTouch.AddressBookUI;
using MonoTouch.AddressBook;
ABPeoplePickerNavigationController _contactController = new ABPeoplePickerNavigationController ();
AppDelegate.navigation.PresentViewController (_contactController, true, null);
_contactController.Cancelled += delegate {
AppDelegate.navigation.DismissViewController (true, null);
return;
};
_contactController.SelectPerson += delegate(object sender, ABPeoplePickerSelectPersonEventArgs e) {
_importedContact = e.Person;
AppDelegate.navigation.DismissViewController (true, delegate {
// What to do when you dismiss the picker here.
});
};
e.Person is only going to give you the whole contact. You would want to do something like:
e.Person.GetEmails().FirstOrDefault
Hope this helps

SimpleMultilineEntryElement insertion point failure

I'm using the MonoTouch SimpleMultilineEntryElement from the monotouch-element-pack (originally just MultilineEntryElement) and when I tap to insert somewhere in existing text, I can insert a single character and then the insertion point jumps to the end of the string. I've checked the sample application and the behaviour is the same so it appears to be something in the library rather than something I'm doing incorrectly. Has anyone else had this problem and resolved it?
In the SimpleMultilineEntryElement change the FetchValue to the following, basically what is happening is the current position in the text is being lost with each modification of the text taking you to the end of the text each time.
With the following code you are saving the current position in the text at the start and repositioning the cursor at the end.
public void FetchValue() {
if (entry == null) {
return;
}
int currentPos = entry.SelectedRange.Location;
var newValue = entry.Text;
if (newValue == Value) {
return;
}
Value = newValue;
if (Changed != null) {
Changed(this, EventArgs.Empty);
}
if (currentPos > 0) {
NSRange newPos = new NSRange(currentPos, 0);
entry.SelectedRange = newPos;
}
}
Not 100% sure if this is the issue, or if it can be an issue. But I thought entryKey and cellkey had to be unique to a specific element. Both are set to MultilineEntryElement and not SimpleMultilineEntryElement.
Was thinking if you previously have used a MultilineEntryElement it could be getting dequeued in GetCell.
var cell = tv.DequeueReusableCell (CellKey);
Maybe...

Why is UILabel not updating?

I have created a view that shows lost connection messages to users which pops over the current view. I want to update the view periodically based on connection status changes.
I can properly get the view and change the text of a label (verified with WriteLines), but nothing changes on the actual display. I even tried removing the view and readding it and calling SetNeedsDisplay, but nothing seems to help.
I have a global variable called OverView:
public static UIView OverView;
I create the label subview, add it to the overview and pop the overview in front of the current view:
UILabel labelTitle = new UILabel();
labelTitle.Text = title;
UIView labelTitleView = (UIView) labelTitle;
labelTitleView.Tag = 5000;
OverView.AddSubview(labelTitleView);
curView.InsertSubviewAbove(OverView, curView);
curView.BringSubviewToFront(OverView);
And then at a later time, I try to modify it like this from another function:
if ((OverView != null) && (OverView.Subviews != null))
{
for (int i = 0; i < OverView.Subviews.Length; i++)
{
WriteToConsole("Type: " + OverView.Subviews[i].GetType());
if (OverView.Subviews[i] is UILabel)
{
WriteToConsole("Found Label with Tag: " + ((UILabel)(OverView.Subviews[i])).Tag + " Text: " + ((UILabel)(OverView.Subviews[i])).Text);
if (((UILabel)(OverView.Subviews[i])).Tag == 5000)
{
WriteToConsole("Setting subview Title to: " + lostConnectionTitle);
lock (overViewLocker)
{
appReference.InvokeOnMainThread(delegate
{
UILabel tempLabel = ((UILabel)(OverView.Subviews[i]));
tempLabel.Text = lostConnectionTitle;
OverView.Subviews[i].RemoveFromSuperview();
OverView.AddSubview(tempLabel);
OverView.BringSubviewToFront(tempLabel);
OverView.SetNeedsLayout();
OverView.SetNeedsDisplay();
WriteToConsole("SetNeedsDisplay");
});
}
}
}
}
}
Have you tried to use delegate methods on your label, and change their value when events occur ?
For example, if your event is clicking on a button, you should have something like that:
yourLabel.Text = "Init";
buttonExample.TouchUpInside += (sender, e) => {
yourLabel.Text = "I touched my button";
};
When your View loads, you'll see "Init" and your button and once you click on it, the label text changed.
Xamarin has some explanation about events and delegate methods here.
I hope that helped.

Highlight the selected cell in a DataGridView?

In my code below, I'm showing a context menu when the user right-clicks on a cell in my DataGridView. I'd also like the cell that the user right-clicks on to change background color so that they can see the cell they've "right-click selected". Is there a way to add something to my code below so that this occurs?
private void dataGridView2_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
ContextMenu m = new ContextMenu();
MenuItem mnuCopy = new MenuItem("Copy");
mnuCopy.Click += new EventHandler(mnuCopy_Click);
m.MenuItems.Add(mnuCopy);
int currentMouseOverRow = dataGridView2.HitTest(e.X, e.Y).RowIndex;
m.Show(dataGridView2, new Point(e.X, e.Y));
}
}
So obviously you've hacked into my workstation and have seen some of the stuff I've worked on recently. I exaggerate a bit because I didn't do exactly what you're trying to do but with a little bit of tweaking I was able to.
I would modify your MouseClick event to get the DGV's CurrentCell. Once you have it, set the CurrentCell's Style property with the SelectionBackColor you want. Something like this:
// ...
DataGridView.HitTestInfo hti = dataGridView2.HitTest(e.X, e.Y);
if (hti.Type == DataGridViewHitTestType.Cell) {
dataGridView2.CurrentCell = dataGridView2.Rows[hti.RowIndex].Cells[hti.ColumnIndex];
dataGridView2.CurrentCell.Style = new DataGridViewCellStyle { SelectionBackColor = System.Drawing.Color.Yellow};
}
//...
The above is a bit 'air code-y' (in other words I haven't attempted to merge it with your code and run it) but I hope you get the idea. Notice that I check through the hit test that a cell was clicked; if you don't do this and the user does not click a cell you might have some problems.
Now there's the problem that this code will change the SelectionBackColor for the all the cells you right click. That's easy to restore this property in the DGV's CellLeave event:
private void dgvBatches_CellLeave(object sender, DataGridViewCellEventArgs e) {
dataGridView2.CurrentCell.Style = new DataGridViewCellStyle { SelectionBackColor = System.Drawing.SystemColors.Highlight };
}
I'll have to remember this visual affect; thanks for asking the question.
