Hello again,

I have more less code something like this:

<telerik:RadGridView>
   <telerik:RadGridView.Columns>      
      <telerik:GridViewDataColumn UniqueName="Title" />
      <telerik:GridViewHyperLinkColumn UniqueName="Link" IsReadOnly="True" />
   </telerik:RadGridView.Columns>
</telerik:RadGridView>

So it is a grid with has two columns text and hyperlink. I would like to block editing of hyperlink column. When user is adding or editing row even the IsReadOnly column is set he still is able to modify it. Is it a bug or a feature?

Hi Konrad,

 

The GridViewHyperlinkColumn/GridViewDynamicHyperlinkColumn columns are not editable. The editable columns are GridViewDataColumn and GridViewComboBoxColumn, you may read more about this here. If you need to achieve some custom functionality you may predefine the CellTemplate/CellEditTemplate of GridViewDataColumn in an appropriate manner.

 

Best wishes,

Thanks for replay.

Probably you are wrong. By default user can edit GridViewHyperlinkColumn. To disable this you have to do some custom implementation. To edit this column user has to be in edit mode and switch to hyperlink column using TAB key. Below are sample code, screenshots.

<telerik:RadGridView x:Name="ucGrid" AutoGenerateColumns="False">
   <telerik:RadGridView.Columns>
       <telerik:GridViewDataColumn UniqueName="Title" />
       <telerik:GridViewHyperlinkColumn UniqueName="Hyperlink" IsReadOnly="True" />
   </telerik:RadGridView.Columns>
</telerik:RadGridView>

public class Entry
{
public string Title { getset; }    public string Hyperlink { getset; } }

public partial class MainPage : UserControl
{
   public MainPage()
   {
      InitializeComponent();
 
      ucGrid.ItemsSource = new ObservableCollection<Entry>
      {
         new Entry{Title = "Title1", Hyperlink="http://web1.com"},
         new Entry{Title = "Title2", Hyperlink="http://web2.com"},
         new Entry{Title = "Title3", Hyperlink="http://web3.com"},
      };
   }
}

Hello Konrad,


Please accept my apology for the omission. We need to some time to investigate why the IsReadOnly property is not working for these column types and how the editing is handled internally. For the time being you may also use the following workaround, through handling the BeginningEdit event of RadGridView as shown below:

private void RadGridView_BeginningEdit(object sender, Telerik.Windows.Controls.GridViewBeginningEditRoutedEventArgs e)
        {
            if (e.Cell.Column is GridViewHyperlinkColumn)
            {
                e.Cancel = true;
            }
  
        }


I have also updated your Telerik points accordingly!


All the best,
