Vertical scroll problem

[Ivano]

Hi to all,
I have a problem in a RadGridView with the vertical scrollbar.
I've attacched a DataTable to my gridview DataSource, and all works well, then I've hidden some rows, but at this point the vertical scrollbar doesn't allow me to see all the rows visible, in the sense that when I reach the bottom edge of the scrollbar, there are still a lot of row in the grid view, but I cannot see them.
The code:

    myGridView.DataSource = myDataTable;
            }
            
            if (myCheckBox.Checked)
  {
                foreach (GridViewRowInfo row in myGridView.Rows)
{
                    if ((bool)row.Cells["myColumn"].Value == false)
   {
                        row.IsVisible = false;
                        row.InvalidateRow();
                    }
                }
            }
            else
    {
                foreach (GridViewRowInfo row in myGridView.Rows)
                 {
                    row.IsVisible = true;
                    row.InvalidateRow();
                }
            }

Hello Ivano,

Thank you for writing.

I confirm the issue and I logged it in our issue tracking system. You can track its status by using the following link. I updated also your Telerik points accordingly.

You can work around the issue by calling the UpdateScrollRange method explicitly. Consider the sample below:

this.radGridView1.TableElement.RowScroller.UpdateScrollRange();

I hope it helps.
 
All the best,
Jack

I am using Telerik UI for WinForms 2014 Q3 1202 and have what seems to be an identical vertical scrolling problem. Has a better fix or circumvention evolved since this post? And where, in the problem context presented here by Ivano, are you suggesting to add the single line workaround?
