Find Control & setvalue to combobox or checkbox in GridView

Hi,
I want to get the checkbox and combobox controls within a RadGridView and want to modify a column in the same row. How it can be achieved?

Problem 1:
Want to save user name in a grid column within same row when I checked the checkbox value to true.
Problem 2:
Want to filter or rebind the combobox when a value is selected in another adjacent combobox as we have in Country and city relation.

Let me know if further explanation is required.

Thanks

Hi!

I am inserting new rows with the INSERT key. Once a row was inserted, it can be edited by the user.
I want to delete the newly inserted row, if the user cancels the edit mode with the ESC key.

What is the easiest way to achieve this?

Thanks and regards,

RadSlider SelectionEnd goes beyond Maximum

Hi,

I expect the SelectionEnd and SelectionStart values to stay within the bounds of the Maximum and Minimum but they don't. I created a small sample app that demonstrates this behavior.

View:

<Grid>

<StackPanel>

<StackPanel Orientation="Horizontal" Height="50">

<Label Content="Upper Thumb" />

<TextBox Width="300" Height="35" Text="{Binding Path=SelectionEnd}" />

</StackPanel>

<telerik:RadSlider Name="radSlider"

VerticalAlignment="top"

Width="25"

Height="200"

Margin="0 10 5 0"

IsSelectionRangeEnabled="True"

TickPlacement="None"

Minimum="0.0"

Maximum="1.0"

Orientation="Vertical"

SelectionStart="{Binding Path=SelectionStart, Mode=TwoWay, FallbackValue=0.25}"

SelectionEnd="{Binding Path=SelectionEnd, Mode=TwoWay, FallbackValue=0.5}"

LargeChange="0.05"

SmallChange="0.05" />

<StackPanel Orientation="Horizontal" Height="50">

<Label Content="Lower Thumb" />

<TextBox Width="300" Height="35" Text="{Binding Path=SelectionStart}" />

</StackPanel>

</Grid>

Code behind:

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

var vm = new SliderViewModel();

DataContext = vm;

}

ViewModel:

public class SliderViewModel : INotifyPropertyChanged

{

public SliderViewModel()

{

_selectionStart = 0.25;

_selectionEnd = 0.5;

}

private double _selectionStart;

public double SelectionStart

{

get

{

return _selectionStart;

}

set

{

if (_selectionStart != value)

{

_selectionStart = value;

OnPropertyChanged("SelectionStart");

}

private double _selectionEnd;

public double SelectionEnd

{

get

{

return _selectionEnd;

}

set

{

if (_selectionEnd != value)

{

_selectionEnd = value;

OnPropertyChanged("SelectionEnd");

}

public event PropertyChangedEventHandler PropertyChanged;

protected virtual void OnPropertyChanged(String propertyName)

{

var handler = PropertyChanged;

if (handler != null)

{

handler(this, new PropertyChangedEventArgs(propertyName));

}

Am I missing a property on the slider that will prevent this behavior or do I have to catch it manually?

Thanks,
Josh

ScrollIntoView(selectedItem) doesn't take into account grouping headers when refreshing grid

Hello

I seem to have found an issue with the ScrollIntoView method of the RadGridView. If we take a well populated grid so that it is necessary to scroll to reach the bottom, with the entries grouped in various groups.
When modifying an item at the bottom of the grid, when the grid refreshes, it scrolls to a point above the selected item, the height above where it should be seems to coincide exactly with the combined height of each of the grouping rows.

Thanks

Escape key and RoutedCommand

I have setup in my code a RoutedCommand for escape key:

public static RoutedCommand CloseFormCommand = new RoutedCommand();
CloseFormCommand.InputGestures.Add(new KeyGesture(Key.Escape));

This works fine when the keyboard focus is on a control like a textbox in the form. But as soon as I click on the Grid and it is set to Edit mode pressing the Escape key will just finish the edit mode and it won't call the command unless I set the cursor back to the textbox by mouse and press the Escape key. How can I fix this problem?

[Solved] Unsupported File format

Thank you for the new RadRichTextBox.
I installed the new Q1 for 2011 and tried the Telerik Editor example.
Works fine, but... when I try to open or save documents as .docx (or as richtextformat) I get a messagebox: "Unsupported File format".

Office 2010 (Norwegian) is installed.
