[Solved] GridView not updating

[John]

I have the following situation.

        private void radMenuItem1_Click( object sender, EventArgs e )
        {
            dlgAssignSplits dlgSplits = new dlgAssignSplits();
            if ( dlgSplits.ShowDialog() == DialogResult.OK )
            {
                //dlgSplits.Task
                int insertAt = FindRowPosition();
                ClipGrid gridItem = new ClipGrid();
                List<ClipGrid> gridItemsList = UpdateClipTaskGrid();  //Gives back 6 rows
                //gridItem = gridItemsList[insertAt];   // Changes the values in the row.
                gridItem.Task = dlgSplits.Task;
                gridItem.AssignedArtist = dlgSplits.Artist;
                gridItem.AssignStatusDesc = dlgSplits.Status;

                gridItemsList.Insert( insertAt, gridItem );  //gridItemsList has 7 Rows now

                grdClipTask.DataSource = gridItemsList;
                grdClipTask.Refresh();  //Form displays only 6 Rows.

                dlgSplits.Dispose();
            }
        }

Please help me figure out why the stinkin grid won't update.

Hi John,

Thank you for contacting us. I guess that using the Update function with a reset parameter might fix the issue you are experiencing:

RadGridView1.GridElement.Update(GridUINotifyAction.Reset);

Please note that you have to use this with caution because it can slow down the performance of your grid substantially.

I am not sure what exactly causes the issue. Can you send us a sample application so that we can debug it and perhaps provide a fix for Q2 2009 or better work-around for the time being. Please note that you have to open a new support ticket so that you can attach files.

This seems like the common answer these days.  Do you think I have time to "create you a small sample app" to debug your code every time I find a bug?  Guess I should have purchased the component Art tools.

Hi John,

Please excuse me for not noticing that you are using a list -- you need a BindingList. The latter implements several interfaces that notify the grid about changes in the collection and hence update the UI. I hope that this helps. Please write me back if you have more questions.
