I develop automated tests using MS VS 2012 and CodedUI. Our application contains number of teleriks gridviews. For test purposes I need to obtain every row from those gridviews, but the problem is I can only obtain limited number of rows due to virtualization. Tried scrolling new rows into view to realize them and adding them to array/collection
code snippet:

// determine viewport, i.e. how many rows are accessible for that specific panel
             
            for (int m = 0; m < 50; m++)
            {
                try
                {
                    if (!hGridView.GetRow(m).Exists)
                    {
                    }
                }
                catch (UITestControlNotFoundException)
                {
                    viewPort = m - 1;
                    break;
                }
            }
 
            // no extra scrolling required, all rows are accessible
            if (rowCount <= viewPort + 1)
            {
                for (int m = 0; m < rowCount; m++)
                {
                    rows_output[m] = hGridView.GetRow(m);
                }
                return rows_output;
            }
 
            //get all accessible rows before scrolling to expose the rest
            for (int m = 0; m <= viewPort; m++)
                {  
                    rows_output[m] = hGridView.GetRow(m);
                    col1.Add(hGridView.GetRow(m));
                }
 
            for (int m = 0; m < viewPort; m++) { Keyboard.SendKeys("{DOWN}"); }
             
            for (int i = 0; i <= rowCount - viewPort - 2; i++)
            {
                 
                try
                {
                    // check the row to add isn't a duplicate
                    if (!col1.Contains(hGridView.GetRow(viewPort)))
                    {
                        col1.Add(hGridView.GetRow(viewPort));
                    }
 
                    rows_output[i + viewPort + 1] = hGridView.GetRow(viewPort);
                }
                catch (UITestControlNotFoundException)
                {
                    // if for some reason gridview becomes inaccessible
                    break;
                }
 
                //scroll the grid down a bit
                Keyboard.SendKeys("{DOWN}");
 
            }
code works ok when i'm debugging, but when i'm just running the test resulting array is mess, the same ~10 rows repeats again and again
What's wrong with this code? Is there any other reliable way to get all the data from virtualized grid?

Hi,

If the row is not in the View port, then there is not GridviewRow realized for displaying the respective Item. When the virtualization of RadGridView is turned on (which is by default), its elements are created when they should be brought into view. You can take a look at this article for a reference on UI Virtualization.

May I ask you why do you need to access all the GridViewRows? What level do you use?
