Programmatically scrolling to last column in empty gridview

[haagel]

I need to scroll to the last column (right-most) when I open a form with a RadGridView.

I use this code to scroll:

MyGridView.ScrollIntoView(null, MyGridView.Columns[MyGridView.Columns.Count - 1]);

This works, but only when there is data in the gridview. When I try to run this line of code before the gridview has any data, nothing happens. Am I doing something wrong, or is this just not possible?

Hello haagel,

Please try the following code :

GridViewScrollViewer scrollViewer = this.RadGridView1.ChildrenOfType<GridViewScrollViewer>().First();
            scrollViewer.ScrollToRightEnd();

* for this you will need to add an "using Telerik.Windows.Controls" .

All the best,

I tried writing your code last in the constructor of the user control that has the grid, but when I ran the application I got an exception:
InvalidOperationException: Sequence contains no elements

I put the code in an event handler for the Loaded event of the user control instead, and now it works.

Thanks Pavel!

Hi Haagel,

  You get this error because no GridViewScrollViewer can be found when you execute the code in the constructor. The reason for this is that all UI elements are created a bit later. Please use the Loaded event as a signal for determining when the UI structure is ready.
