I was wondering if it was possible to replace one control in a TableLayoutPanel with another at runtime. I have a combo box and a button which are dynamically added to the TableLayoutPanel at runtime, and when the user selects an item in the combo box and hits the button, I'd like to replace the combobox with a label containing the text of the selected combo box item.
Basically, if I could simply remove the control and insert another at it's index, that would work for me. However I don't see an option like "splice" or "insert" on the Controls collection of the TableLayoutPanel, and I was wondering if there was a simple way to insert a control at a specific index. Thanks in advance.
Fixed this by populating a panel with the two controls I wanted to swap and putting that into the TableLayoutPanel. Then I set their visibility according to which I wanted to see at what time.
This is what I've been able to come up with for what I needed. It gets the position of the ComboBox and makes a new label using the selected value.
// Replaces a drop down menu with a label of the same value
private void lockDropMenu(ComboBox dropControl)
{
TableLayoutPanelCellPosition pos = myTable.GetCellPosition(dropControl);
Label lblValue = new Label();
myTable.Controls.Remove(dropControl);
if (dropControl.SelectedItem != null)
{
lblValue.Text = dropControl.SelectedItem.ToString();
lblValue.Font = lblValue.Font = dropControl.Font;
// Just my preferred formatting
lblValue.AutoSize = true;
lblValue.Dock = System.Windows.Forms.DockStyle.Fill;
lblValue.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
myTable.Controls.Add(lblValue, pos.Column, pos.Row);
}
}

/* Upon execution, the drop down button is clicked but the option listed below is not clicked. How to solve this problem?
In stead of searching for an image, search for the list or dropdown control using a wpfCombobox, winCombobox or HtmlComboBox control. There you set the selectedItem property to the value you want. that is the most robust way of selecting an item in the UI. so e.g. :
ApplicationUnderTest aut = ApplicationUnderTest.Launch(#"yourapp.exe");
WpfComboBox cbBox = new WpfComboBox(aut);
cbBox.SearchProperties.Add(WpfComboBox.PropertyNames.AutomationId,"cmbCountries");//AutomationId == xName roperty
cbBox.SelectedItem = "your value";
I am using c1truedbgrid. I have columns added in the grid with one column having button which is displayed is every row. I need to disable the button in a particular row depending on some business logic. How this can be done?
I am not sure why there aren't any answer.
Its fairly simple. Lets say I want to disable the buttons from those rows where ID is even.
for(int i = 0; i< c1truedbgridobject.Splits[0].Rows.Count; i++)
{
if(Convert.ToInt32(c1truedbgridobject[i,1].ToString())%2 == 0)
{
//Disable here
}
}
However the disable part is dependent on how you are adding button to a cell. Since add button is referenced to whole column and not to a particular cell.
Anyhow using a OwnerDrawCell is also an option.
EDIT:
This seems as a limitation of C1TrueDBGrid. You may use C1FlexGrid as an alternative.
You need to make property of that column as "locked=True" as Below example when you initializing grid.
C1TrueDbGridName.Splits(0).DisplayColumns("YourColumnNameHavingButton").Locked = True
it will make your row not to be editable
I've encounter a problem with editable table cells. I'm using the TableView in my project just as the Tutorial on Oracle.
According to it, I use the setCellFactory method to reimplement the table cell as a text field with the help of the TextFieldTableCell class. However, I found the steps is a little complex to get to the point where the cell can be edited:
Let the table cell be selected by using direction key.
Press “Enter” to converts the cell to a text filed so that it is ready to be edited.
Clicking in the text field allows the contents to be edited
The problem is step 3, that you must use the mouse to click before you can input data in this table cell.
So, is there a solution to avoid step 3? That is the text field allows the data inputting when you just press “Enter”(step 2).
By the way, English is not my native language. Hope I have made myself clear.
The Node can be focused manually. The TextFieldTableCell is a TableCell that has a Node (Graphic) TextField which will be rendered when the cell is in editing mode. You need to focus to this textField manually but by using TextFieldTableCell you cannot access to the textField. However if you would prefer the alternative way described in the tutorial you are referring, then you have a chance to focus. The only changed method from that tutorial is:
#Override
public void startEdit() {
super.startEdit();
createTextField();
setText(null);
setGraphic(textField);
textField.selectAll();
// Set the focus
Platform.runLater(new Runnable() {
#Override
public void run() {
textField.requestFocus();
}
});
}
To start editing in a TableView without mouse-click event, invoke TreeView.edit(rowIndex, tableColumn);
For example:
//create tableview object
TableView<YourModel> tableView = new TableView<>();
//create column
TableColumn<YourModel, String> column = new TableColumn<>("Property Name");
//add column to tableview
tableView.getColumns().add(column);
//... your cell factory and the rest
//add an item
tableView.getItems().add(new YourModel());
//if you want to edit the selected item, get its index
int selectedIndex = tableView.getSelectionModel().getSelectedIndex();
//fire edit
tableView.edit(selectedIndex, column);
I'm trying to make a box that allows you to select some variables, and re-order the ones that are selected. So the LEFT box starts filled, the RIGHT box starts empty. You move items from the left to the right, and on the right you can re-arrange their order (with the up and down buttons). This lets you pick what items you want and in what order (for sorting purposes in another section of the program).
The layout I'm going for looks like of like this:
Unfortunately, it's coming out like... well... :-(
The functionality I'm looking for all works. Yay. I am just having a very hard time with the layout. I think if I can reach the following four primary objectives, I'll be set.
How can I get the OK and CANCEL buttons on the bottom instead of above the multis?
How can I get the multis to have a pre-set size (let's say... 10)
How can I get the arrow buttons to be stacked vertically instead of horizontally?
How can I get the arrow buttons to be between the two multis?
I figure each of these particular objectives are probably one-liners, perhaps a little bit of plumbing here and there...
On a side note, I'm using GridLayout - this might be a poor choice. Is there a better choice for something like this?
Without further ado, here's the code that generates this horrid mess...
#Override
protected Control createDialogArea(Composite parent) {
parent.getShell().setText("Multi-sort");
Composite dialogcomp = new Composite(parent, SWT.NONE);
dialogcomp.setLayout(new GridLayout(3, false));
available = new List(getShell(), SWT.BORDER | SWT.V_SCROLL);
for(String t : MultiSortDialog.availableNames) {
available.add(t);
}
used = new List(getShell(), SWT.BORDER | SWT.V_SCROLL);
for(String t : MultiSortDialog.usedNames) {
used.add(t);
}
createButton(parent, ADD, ">", false);
createButton(parent, REM, "<", false);
createButton(parent, UP, "^", false);
createButton(parent, DOWN, "V", false);
return dialogcomp;
}
I would suggest you simple use the Dialog's default OK and Cancel buttons and not trying to lay out your own. SWT has a nice system for placing them in the system default location (i.e., on Mac OS, the OK button will be on the right, which is the correct location.)
Don't use Dialog.createButton() to create buttons. This creates a button on your dialog which, although it sounds like what you want to do, actually isn't. This creates a button in the style of OK or Cancel buttons, expected to be placed in the button bar composite that the Dialog class owns and styled appropriately for the bottom row OK/Cancel buttons. You want to create a new Button in the composite you're creating. That is:
Button addButton = new Button(dialogcomp, SWT.PUSH);
addButton.setText(">");
addButton.addSelectionListener(...);
To stack the buttons vertically, create a new composite inside dialogcomp to contain them.
To put the arrow buttons between the Lists, you need to ensure that you add things in the correct order. With a GridLayout, you need to add widgets in the order that you want them to appear.
Other points:
Don't change the title of the dialog by calling Shell.setText(). Call setText() in your
Don't try to parent your Lists inside the parent shell. You're given a composite to put things in. This will wreak havoc on your layouts. You're basically hoisting widgets up into things you don't own and don't layout. Instead, put it in the Composite you created.
You may also wish to create buttons with the type SWT.ARROW | SWT.LEFT instead of simply drawing a < sign. It may be more visually appealing. Just something to investigate.
A simple rearrangement of your code, creating Buttons properly, and creating a new composite to hold the buttons, will get you much closer:
Composite dialogcomp = new Composite(parent, SWT.NONE);
dialogcomp.setLayout(new GridLayout(3, false));
available = new List(dialogcomp, SWT.BORDER | SWT.V_SCROLL);
for(String t : MultiSortDialog.availableNames) {
available.add(t);
}
Composite buttonComposite = new Composite(dialogcomp, SWT.NONE);
buttonComposite.setLayout(new GridLayout(1, false));
Button addButton = new Button(buttonComposite, SWT.PUSH);
addButton.setText(">");
Button removeButton = new Button(buttonComposite, SWT.PUSH);
removeButton.setText("<");
Button upButton = new Button(buttonComposite, SWT.PUSH);
upButton.setText("^");
Button downButton = new Button(buttonComposite, SWT.PUSH);
downButton.setText("v");
used = new List(dialogcomp, SWT.BORDER | SWT.V_SCROLL);
for(String t : MultiSortDialog.usedNames) {
used.add(t);
}
This will probably get you pretty close to what you want. However, you will probably want to apply GridDatas for each of your instances. For example, your two Lists will probably want to grab and fill horizontally and vertically to fill the layout as the Dialog is resized. But I'll leave that as an exercise for the reader.
I'm trying to set the assigned value to a YUI Menu Button in order to use values from previous operations.
Something like remembering previous choices.
For label I already know that I can change it with:
button.set("label", "my label")
unfortunatelly I cannot change the value using: button.set("value", "my value")
Any ideia on how can I do this?
Other way would be to force a selection, but I have no ideia on how to do that.
Thanks
just found out that you can use:
var menu = button.getMenu();
var item = menu.getItem(index);
button.set("selectedMenuItem", item);
all that is left for me now is finding the needed index
