Need Scrollbars enabled while RadGridView is disabled "part 2"

[Terje Johansen]

Hi, 

I have a grid that is shown in two different windows...(different windows same grid)
In one of the windows the grid is enabled and the user can edit the grid, but in the other window the grid is disabled.
My problem is that the grid scrollbar is disabled in the window where the grid is disabled...

I read the thread (hence the title on this post) on the forum about someone with a similar issue, but the solution for 
that case, a style targeting the GridViewRow, will not help me I'm afraid.

Is there another way to disable the grid but not the scroll?

Please advice!

Hello Terje Johansen,

 You could set your GridView to be ReadOnly. That way editing the data is disabled, but you still may benefit from the other functionality of the RadGridView.

Would this approach be good for your case?

No, because even if I set it to ReadOnly you can still open up context menues and insert rows **
unless I add a lot of extra checks all over the place to see if grid is readonly or not.
By setting "grid.IsEnabled = false" I avoid all this 

** e.g. Keyboard Insert will insert a new row because it's the same grid in both windows and this may have been enabled when first opened

I am using a RadGrid and want my scrollbar to be enabled when i disable the grid. 

1.  How can I do this?
2.  Why would disabling the scroll be the default for the RadGrid, many people need it enabled.

[Terje Johansen]

The following code solved the problem for me:

Add styles:
       <!--Disabled row in RadGridView-->
	<Style x:Key="DisabledRow" TargetType="{x:Type GridView:GridViewRow}">
		<Setter Property="IsEnabled" Value="False" />
	</Style>
 
	<!--Enabled row in RadGridView -->
	<Style x:Key="EnabledRow" TargetType="{x:Type GridView:GridViewRow}">
		<Setter Property="IsEnabled" Value="True" />
	</Style>

Use styles in your code (ViewModel):

//Original values
    var canDelete = View.GebyrGrid.CanUserDeleteRows;
    var canInsert = View.GebyrGrid.CanUserInsertRows;
 
   if (perform check to see if grid should be disabled or enabled )
   {	
         // disable grid 
        View.GebyrGrid.RowStyle = (Style)Application.Current.MainWindow.FindResource("DisabledRow");
	View.GebyrGrid.CanUserDeleteRows = false;
	View.GebyrGrid.CanUserInsertRows = false;     
        View.GebyrGrid.Tag = "DisabledRow";         
}
else
  {
      // enable grid
View.GebyrGrid.RowStyle = (Style)Application.Current.MainWindow.FindResource("EnabledRow");
View.GebyrGrid.CanUserDeleteRows = canDelete;
View.GebyrGrid.CanUserInsertRows = canInsert;
    View.GebyrGrid.Tag = "EnabledRow";
}
//if you have a contextmenu it too must be disabled (code-behind file)
private void GebyrGridOpened(object sender, RoutedEventArgs e)
        {
            if (Equals(GebyrGrid.Tag, "DisabledRow"))
            {
                ((RadContextMenu)sender).IsEnabled = false;
                return;
            }
          
            ((RadContextMenu)sender).IsEnabled = true;

        }

I am not looking to disable each row.  I want the grid disabled but I want customers to be able to scroll and see what information is available.

[Terje Johansen]

I think that this is the only way you can achieve what you want....
to disable the grid, but still have scrollbars that works you have to disable each row as shown in the code-example I posted.

[Stacy]

I think telerik needs to make this part of their control as many people are asking for it

[Stacy]

Where is the "style" xml placed?

[Terje Johansen]

I have a separate xaml file for all my Telerik styles and refer to them as DynamicResource, but you can also place the two styles in the xaml file where your grid is (as Resources) and refer to them as StaticResource

[Stacy]

I haven't been able to place these style tags in the aspx where my grid is, is that not possible?  I am using a RadGrid.

[Terje Johansen]

You might need a different syntax/approach for aspx (ASP.NET) files.
I'm using xaml files (WPF).

You can just wrap your radgridview in grid and ScrollViewer


like this

<Grid>
    <ScrollViewer VerticalScrollBarVisibility="Visible" CanContentScroll="True" >
        <telerik:RadGridView
                     ItemsSource="{Binding Parameters, UpdateSourceTrigger=PropertyChanged}"
                     IsEnabled="False">
        </telerik:RadGridView>
    </ScrollViewer>
</Grid>
