Problem select cell and change Background column

Hello,

I want to change background color to gridview column when user click in a cell. I have this code:

private void SelectColumn (string columnName)
{

  foreach (var column in GridViewNew.Columns)
                {
                    if (column == columnName)
                    {
                        ((GridViewDataColumn)column ).Background = new SolidColorBrush(Color.FromArgb(255, 165, 215, 241));

                    }
                    else
                    {
                        ((GridViewDataColumn) column ).Background = new SolidColorBrush(Colors.White);
                    }
                }
}

At first it works, but when i click over another cell, the column chages its color but column´s footer doesn´t.

Copying cell content problem

Hi,

I'm using VS2008 and Telerik V2010.3.1314.35 and I have a RadGridView with Date, Time and string column and I don't know why but when I try to copy cell content of cell type other that string, I have an error...

When I copy cell content of a data cell type other than string, "e.Value" always equal null....

How I can handle any cell data type when I try to copy a cell content???

Thank's

private void SignCtxVisitsGrid_CopyingCellClipboardContent(object sender, GridViewCellClipboardEventArgs e)

{

e.Cancel =

false;

if (mSelectedCell != null && mSelectedCell.Column == e.Cell.Column)

{

try

{

System.Windows.Forms.

Clipboard.SetText(e.Value as string);

}

catch (Exception exc)

{

}

else

{

e.Cancel =

true;

}

How to set Variants when using MVVM

Basing my implementation on your RadRibbonView MVVM example I need to be able to set the variants. But this does not appear to be possible. If it is can you please supply an example where the groups are derrived from the ViewModel.

Thanks

Strange behaviour of minimized Icons

Edit: Title should be "Strange behaviour of minimized ITEMS" (not icons, but I can't change the Title)

Dear Support,

I'm just testing your controls because the Infragistics-Suite seems not to support MVVM in any way.
Your OutlookBar works great, but I have an issue/question about the "Caption/Header/Text" of minimizedItems.
Please take a look at following XAML

<telerik:RadOutlookBar QuickStart:ThemeAwareBackgroundBehavior.IsEnabled="True" telerik:Theming.Theme="Office_Blue" ItemsSource="{Binding OutlookEntries}" Height="234" HorizontalAlignment="Stretch" Margin="211,6,160,31" Name="RadOutlookBar1" VerticalAlignment="Stretch" Width="229">

<telerik:RadOutlookBar.Resources>

<Style TargetType="{x:Type telerik:RadOutlookBarItem}">

<Setter Property="Header" Value="{Binding Header}"/>

<Setter Property="SmallIcon" Value="{Binding SmallImage}"/>

<Setter Property="Title" Value="{Binding Header}"/>

<Setter Property="Icon" Value="{Binding LargeImage}"/>

</Style>

</telerik:RadOutlookBar.Resources>

</telerik:RadOutlookBar>

The Items are shown correctly. But if I'm using the slider in order to minimize the Items, the SmallIcon together with the ClassName will be shown at each "minimizedItem" in the outlookbar at the bottom. I don't understand why.

I have seen your MVVM-Binding-Sample in which you used ItemMinimizedTemplate

<telerik:RadOutlookBar.ItemMinimizedTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal">

<TextBlock Text={Binding Header}/>

</StackPanel>

</DataTemplate>

</telerik:RadOutlookBar.ItemMinimizedTemplate>

I could use this DataTemplage and delete the TextBlock inside the StackPanel. Then only the Icon will be shown within minimized Items.
But it seems more clean for me with my code above, instead of retemplating ItemMinimizedTemplate, ItemTemplate, HeaderTemplate etc. The OutlookBar is bound to a CollectionView calles "OutlookEntries" which contains a simple Class with Strings as Header and ImageSources as Icons.

Any hints would be appreciated.

I need to show the search point by adding one pinpoint. do you have some custom search example for openstreetmap?

Please provide some sample code for the openstreetmap.
