[Solved] GridView Group by Column by hide Visibility

[Angie]

Hi

What i would like to do is Hide the visibility of data in a Column but keep the associated grouping in the gridview. I don't want to see repeated product name in the grid View. I have attached a jpg to explain more. What i don't want to see is the part which is crossed off by red. Would i be able to do this using Silverlight Grid View

Hello Ravindranath,

If you define the GroupDescriptor like:

<telerik:RadGridView.GroupDescriptors>
    <telerik:GroupDescriptor Member="Position" />
</telerik:RadGridView.GroupDescriptors>

Then you can just set the Property of the column - IsVisible to "False"

<telerik:GridViewDataColumn DataMemberBinding="{Binding Position}"                                             IsVisible="False"/>

 

All the best,

is there a way to make group descriptors click able hyperlink buttons. Something like in the picture i attached

Hi Ravindranath,

You can define the GroupHeaderTemplate and set its DataTemplate as follows:

<telerik:RadGridView.GroupHeaderTemplate>
     <DataTemplate>
        <HyperlinkButton Content="{Binding Header}" Click="HyperlinkButton_Click"/>
     </DataTemplate>
</telerik:RadGridView.GroupHeaderTemplate>

Afterwards, in case you require this button to open the group for example, you may handle its Click event like:

private void HyperlinkButton_Click(object sender, RoutedEventArgs e)
{
    HyperlinkButton hyperlinkButton = e.OriginalSource as HyperlinkButton;
    GridViewGroupRow groupRow = hyperlinkButton.ParentOfType<GridViewGroupRow>();
    if(groupRow != null)
    {
        this.clubsGrid.ExpandGroup(groupRow.Group);
    }
}

 

Kind regards,

I already did that but that didn't work i couldn't get the hyperlink buttons to be visible. For some reason its not binding to the button. Here is the code i used. I also have attached two images of before adding GroupHeader Template and after adding HeaderTemplate. I could also send the whole project if you want. Let me know

Hi Ravindranath,

 
You need to change the Binding in the Content Property of the HyperlinkButton:

<telerik:RadGridView.GroupHeaderTemplate>
    <DataTemplate>
        <HyperlinkButton Content="{Binding Header}"/>
    </DataTemplate>
</telerik:RadGridView.GroupHeaderTemplate>
