Vertical scroll problem

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();
}
}

Visibility of pages and their location

Hi,

How would one go about programmatically setting the visibility of pages at run time and also is there a way to set the position of the pages along the rows? (i.e. can one page be set to the far right).

Kind regards,

Guy

Frequently Used at the top of the DropdownList

Working in an ERP environment means that users are on the same screens all day long. They tend to pull up the same value from many of the dropdown lists. It would be a nice feature to keep frequently used values at the top of the list, so they can do their work that much easier/quicker.

GridView CheckBox CellValueChanged

Hello,

I have a problem regarding checkboxes inside gridview.
When I check the checkbox at the GUI seem to be checked but the value at the CellValueChanged event that raises is not checked.
Inside the code of the event the checkbox is checked when I click anywhere else on the grid.

My event handler code is

  private void radGridView1_CellValueChanged(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)

        {

            bool isChecked = (bool)radGridView1.CurrentRow.Cells[2].Value;





            if (isChecked == true)

            {

                MessageBox.Show("Thanks you");

            }

        }

Do you have any suggestions ?
PS: I send you a link with a sample project, if that helps. http://www.megaupload.com/?d=W1ACJXFS

Thank you in advance

When we used to install Telerik manually the toolbox in Visual Studio would be filled with the newest controls. Using the Telerik online nuget packages however don't do the same. How do I get the toolbox to be filled after referencing Telerik via the use of a nuget package?
