Hi Experts,

I am doing validation using CurrentCellvalidating event and by using CellEditEnded event i am reloading my Grid's Itemsource. At that time the CurrentCellValidating event gets fired and also the CellEditEnded event gets called once again(both the events are fired 2 times) and after the execution of these events i am getting an null reference exception.

Note: If i didnt reload the Grid ItemSource(Applying new values) then the exception is not occuring.

Please help me anybody, what is going wrong.

Hello,

I have a RadGridView where I am autogenerating columns from a datatable. Some columns need a converter on the values, and the conversion logic is different from column to column.

I am using the following code in the autogenerating column event to set the template to an object with a textblock and the right converter.

                var cellStyle = new Style();
                Setter setter = new Setter();
                setter.Property = TemplateProperty;
                var template = new ControlTemplate();
                var index = "[" + ((RadGridView)sender).Columns.Count.ToString() + "]";
                FrameworkElementFactory spFactory = new FrameworkElementFactory(typeof(System.Windows.Controls.ListBox));

                var value = new MultiBinding();
                value.Bindings.Add(new Binding(index));
                var columnBinding = new Binding();
                columnBinding.Source = e.Column.Header.ToString();
                value.Bindings.Add(columnBinding);
                value.Converter = (IMultiValueConverter)this.FindResource("TupleCreator");

                spFactory.SetValue(DataContextProperty, value);
                spFactory.SetValue(TemplateProperty, (ControlTemplate)this.FindResource("DataTemplate"));

                template.VisualTree = spFactory;
                setter.Value = template;
                cellStyle.Setters.Add(setter);

                e.Column.CellStyle = cellStyle;

This works fine for actually viewing the cells in the grid, and using visualization so that not all of the conversions are done at once. What I need to be able to do is filter and sort by these values, as well as have them in the cells of export to excel.

I have seen something similar done in another control using an unbound column data event.

Thanks,

Eli

I have a problem where the edit mode is conflicting with the drag/drop. The problem happens because the cell goes into edit mode when the mouse is depressed rather than on a mouse up.

The scenario is that the user has clicked on a row. They happen to have clicked in some random cell. Now they want to drag that row. They click in the same cell expecting that they can drag the row but as soon as they press the mouse down, that cell goes into edit mode. So they can't drag.

Is there a way to tell the grid to use mouse-up rather than mouse-down when deciding whether to put it in edit mode.

Thank you,
Valerie

I have a RadGridView populated with data. I have some input controls that allow the user to change the font of the text in the header rows. I tried the following in the code-behind, but it did not work. What is the correct way to do this?

System.Windows.Style headerStyle = new Style();
headerStyle.BasedOn = reportGrid.Columns[0].HeaderCellStyle;
headerStyle.TargetType = typeof(GridViewHeaderCell);
headerStyle.Setters.Add(new Setter(GridViewHeaderCell.FontSizeProperty, 25));
reportGrid.Columns[0].HeaderCellStyle = headerStyle;

Kind Regards,
Albert

Hi, 

I've found an example on how to change the theme at runtime with silverlight but I need to do it with WPF, is it possible ?

Also, I've applied a theme to the VS2010 controls like this:


But I need their theme to follow the application's theme (and follow it too if it changes).

I hope you can help me.

Thanks.

if you setup hierarchy and you want bind / display info in the child grid for the parent row it belongs to..in the xaml/bing how can you get reference to parent row from the child as part of databinding...

<telerik:RadGridView Name="gridView" ItemsSource="{Binding Person}">
    <telerik:RadGridView.ChildTableDefinitions>
                <telerik:GridViewTableDefinition />
    </telerik:RadGridView.ChildTableDefinitions>
    <telerik:RadGridView.HierarchyChildTemplate>
        <DataTemplate>
            <StackPanel>
            <TextBlock Text="{Binding ParentRow.SomeProperty}"/>
            <telerik:RadGridView ItemsSource="{Binding Children}" Name="childGrid" ShowGroupPanel="False" />
            </StackPanel>
        </DataTemplate>
    </telerik:RadGridView.HierarchyChildTemplate>
</telerik:RadGridView>
