I have searched telerik's site for a while now and can not find any mention on how to resize a stacklayoupanel to fit its elements. There are properties that allow resizing to fit its elements; however, these properties are not working for me. I was wondering if there was anyone on here who has used this and can help me out. I have a list view that has listViewVisualItems that do not fit their contents. Rather the contents "leak" out of the visual items below and bleed into the next one.
Here is my custom item class.
public class ChargePlotListViewItem : SimpleListViewVisualItem

private LightVisualElement imageElement;
private LightVisualElement titleElement;
private LightVisualElement bioElement;

To overcome this behavior, please consider allowing the items take their desired size by setting the following property:

For your convenience, here is a simplified version of your code in action:

The task is the following: there is a DataGrid with ComboboxColumns. If user changes cell[2,3] and selected value!=0 then disable cell[3,2]. I wrote the following Handler:
private void grAssessment_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
{
int x = e.Column.DisplayIndex;
int y = e.Row.GetIndex();
grAssessment.GetCell(x, y).IsEnabled = false;
grAssessment.GetCell(x, y).Background = Brushes.LightGray;
}
But it disables appropriate cell in anyway. How to add selected value!=0 condition to this code?
Thanks in advance.
Try to check this out:
1. DataGridComboBoxColumn ItemsSource (for current version only, use your own):
private ObservableCollection<ScoreData> _scores = new ObservableCollection<ScoreData>(
new List<ScoreData>
{
new ScoreData{Score = 1, ScoreVerbal = "the same"},
new ScoreData{Score = 3, ScoreVerbal = "moderate superiority"},
new ScoreData{Score = 5, ScoreVerbal = "strong superiority"},
new ScoreData{Score = 7, ScoreVerbal = "the samvery strong superioritye"},
new ScoreData{Score = 9, ScoreVerbal = "extremely superiority"},
} );
2. Handler code (the handler defined on the data grid):
private void SelectDataGrid_OnCellEditEnding(object sender,
DataGridCellEditEndingEventArgs e)
{
var editingElement = e.EditingElement as Selector;
if(editingElement == null) return;
var selectedData = editingElement.SelectedItem as ScoreData;
if(selectedData == null || selectedData.Score > 1) return;
var dataGridCell = editingElement.GetVisualParentOfType<DataGridCell>();
if(dataGridCell == null) return;
dataGridCell.IsEnabled = false;
}
3. GetVisualParentOfType code (as part of extension class):
public static class VisualTreeExtensions
{
public static T GetVisualParentOfType<T>(this DependencyObject child)
where T : DependencyObject
{
if (child is T)
return child as T;
var parentObject = VisualTreeHelper.GetParent(child);
if (parentObject == null) return null;
var parent = parentObject as T;
return parent ?? GetVisualParentOfType<T>(parentObject);
}
public static T GetChildOfType<T>(this DependencyObject depObj)
where T : DependencyObject
{
if (depObj == null) return null;
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
{
var child = VisualTreeHelper.GetChild(depObj, i);
var result = (child as T) ?? GetChildOfType<T>(child);
if (result != null) return result;
}
return null;
}
}
regards,
I found the following solution
private void grAssessment_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
{
int x = e.Column.DisplayIndex;
int y = e.Row.GetIndex();
DataGridCell cell = grAssessment.GetCell(y, x);
if (((System.Windows.Controls.ComboBox)(cell.Content)).Text != "")
{
grAssessment.GetCell(x, y).IsEnabled = false;
grAssessment.GetCell(x, y).Background = Brushes.LightGray;
}
else
{
grAssessment.GetCell(x, y).IsEnabled = true;
grAssessment.GetCell(x, y).Background = Brushes.White;
}
}

Any ideas? thanks
Most UI elements may only be modified in the UI thread. As your event handler is apparently invoked in a different thread, you have to use the Dispatcher to invoke your code in the UI thread.
private void ConstructChatView(Boolean isChat)
{
Dispatcher.Invoke((Action)(() => chatGrid.Children.Clear()));
}
EDIT: You may also pass more code to the Invoke call by using an anonymous method:
private void ConstructChatView(Boolean isChat)
{
Dispatcher.Invoke((Action)(() =>
{
// more code here
}));
}
Of course you may also put a bunch of code in another method and pass that to the Invoke call:
private void ConstructChatView(Boolean isChat)
{
Dispatcher.Invoke((Action)(() => ConstructChatViewInUI(isChat)));
}
private void ConstructChatViewInUI(Boolean isChat)
{
...
}
OK, this is a weird problem. I have an abstract control that derives from TextBox called Writer, and two classes that derive from it, StdWriter and LngWriter. The difference between them is one is always multiline and the other is not. That's seriously the only difference between the two.
In the OnHandleCreated function, I set the margins with the Win32 SendMessage function. I do it again in OnPaint because WinForms will "forget" to set the margins if I have more than 1 StdWriter (or any derived textbox type) on the same form (this makes no sense either but at least I have a workaround for it).
Now I have the problem that I can't have both of these textboxes on the same form. If I put a StdWriter and a multiline TextBox or a LngWriter and a standard TextBox on the form, it works. If I put 2 MS textboxes on the form, it also works. but let me put a LngWriter and StdWriter together and the LngWriter won't draw its scrollbar right (the vertical is wrong and it just won't draw the horizontal, period) or accept the Enterkey, despite both MultiLine and AcceptsReturn returning true. I can't even paste newlines in because it totally strips them out.
I don't understand this because TextBox derives from the abstract TextBoxBase and I don't have any problems with dozens of different derived textboxes all over my forms. Is it because I'm inserting a second abstract class in the inheritance chain and Visual Studio doesn't like it or what?

I am doing a program in C# for kids with which kids can test their knowledge of Multiplication tables.
I cannot get the value of 'i' in the Result_Leave() function to track which value of the text box array is incorrect.
For Example:
5 X 1 = [ ] <---- an array of textboxes with name Result[i]"
the user enters the value of 5*1 in the text box and my program instantly checks if the entered value is correct or not, using the "Leave" event for the text box.
I have used an array of text boxes...
So I cannot track which Result[i] contains the incorrect value...
I have fired the function "Result_Leave" for each of the text boxes "Result[i]"
Here is the code:

One quick-and-dirty way to do this is to set a value in each TextBox's Tag property. In the for loop inside buttonGo_Click, you could set Result[i].Tag = i;, then in Result_Leave you could do:
int number = (int)((sender as TextBox).Tag);
I am seeking a WinForm control that would provide an autocomplete behavior for multiple space-separated - exactly ala del.icio.us (or stackoverflow.com for that matter).
Does anyone knows how to do that within a .NET 2.0 WinForm application?
ComboBox can autocomplete, but only one word at a time.
If you want to have each word separately autocompleted, you have to write your own.
I already did, hope it's not too long. It's not 100% exactly what you want, this was used for autocompleting in email client when typing in email adress.
