    I have a Windows Form GridView object that I am populating.  I need to allow the user to change the order of items in the list.  To do this, I have two buttons, MoveUp and MoveDown to let them.  For simplicity sake, I have left out a lot of error checking code from my post.

    My problem is that I am calling the GridElement.BeginUpdate() and GridElement.EndUpdate() methods, and for the MoveUp it works just fine, however, oddly enough, the MoveDown causes a flicker effect, which is not supposed to happen (I think) if I am using these methods correctly.

    Here is the portion of my code that is doing this action, as you can see the same code is running in both instances, I am just passing in a different change:


    void btnMoveUp_Click(object sender, EventArgs e)

    private void btnMoveDown_Click(object sender, EventArgs e)

    private void MoveCurrentItem(int indexChange)
        if (radgvScriptsList.SelectedRows.Count == 1)
    file = GetSelectedFile();
            int oldIndex = Files.IndexOf(file);
            Files.Insert((oldIndex + indexChange), file);
            radgvScriptsList.Rows[(oldIndex + indexChange)].IsCurrent =

    Hello sculver,

    I could not reproduce the flickering issue with our latest release Q2 2008 SP1. I strongly recommend updating to this version of RadControls, as a number of improvements have been made since the release of Q2 2008.

    If the problem persists, please send me your application in a support ticket. This will help me locate the issue and address it faster.

    Thank you in advance for your cooperation.
