RadGridView ClearFilter throw ArgumentNullException

Hello,

I'm using telerik 2008 (Version : 2008.3.1217.35, and I can't upgrade in telerik 2009 Q3), when I click on the Clear Filter function in filter expression, if my column contains no elements, I have an ArgumentNullException.

How can I catch this exception, or avoid it.

Thanks

Is it possible SelectAll on Focus of DatePicker InputBox ?

I'd like to be able to select all content of the InputBox of a DatePicker, instead of simply putting the caret at the beggining. Is this possible ?

Thanks,

SelectedItem/CurrentItem Binding Problem

hi,

I have the following wpf

    
            <Telerik:RadGridView   
        
                        Margin="5" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="1"   
        
                        SelectionMode="Single" 
        
                        ItemsSource="{Binding Mode=TwoWay, Path=CurrentCOAContext.Values, UpdateSourceTrigger=PropertyChanged}" 
        
                        SelectedItem="{Binding Mode=TwoWay, Path=CurrentCOAContext.Values.CurrentItem, UpdateSourceTrigger=PropertyChanged}" 
        
                        CurrentItem="{Binding Mode=TwoWay, Path=CurrentCOAContext.Values.CurrentItem, UpdateSourceTrigger=PropertyChanged}" 
        
                        x:Name="GridViewHistory"   
        
                        AutoGenerateColumns="False">

In this code I am expectinting to be visually updated the grid with the value of CurrentItem. But unfortunately it is not shows the row indicator to that row nor the selection. I tried to bind SelectedItem and CurrentItem members independently, but resulting same.

Are there any way to do this ? Because I am fully concentrated to update the visuals with the underlying data (I think that's the best practice of WPF), so I don't want to break this rule with extraordinary codes.

(My version is 2009.3.1208)

thanks,
dogu

RadTreeViewItem highlighted control template size/style

Hi

I have a RadTreeView with several items, as shown here:

http://tinypic.com/view.php?pic=29m6sxs&s=5

Is there a way to change the RadTreeViewItem's highlighting yellow selection bar to not span across until the end of the tree view, but to end when where the tree view item's label ends?

The TreeView may get quite wide so I don't want the selection highlight to span until the rightmost portion of it, so ideally it would span from the beginning of the item until the end of the item.

Many thanks

Hello,

Just updated to version 2009.3.1208.35. Found a problem, well it worked with the last version. When i set the RadCarouselPannel ItemsPerPage to 7 and only display 6 items i need to scroll the items in order to see them. on the last version i didnt need to. I was curious if this is expected and i need to code around this?

here is a quick example

    
            <Window

Deleting Row from Grid or DataTable Associated with Grid

Hello,

When trying to delete specific rows from the WPF grid I get this error when I execute this command:

grid_name.Items.RemoveAt(<position of row to delete>);

The error is: Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead.

When I try deleting row 2 or greater from the datatable I get an error message saying that I've tried deleting an entry in the datatable that does not exist. Essentially an out of bounds error. Strangely enough I can delete the first row.

If I break the association between the grid and the datatable by doing this I can delete whatever row I want.

grid_name.ItemsSource = null;

datatable_name.Rows.RemoveAt(<position of row to delete>);

grid_name.ItemsSource = dataset_name.Tables[0].DefaultView; // I only have 1 datatable in the dataset.

Is this the correct way to delete stuff from the grid?
