Hello Boyan,
Thank you for your reply. Yesterday I implemented a workaround for such issue. Here is a code:
private static int GetColumnIndex(this RadGridView radGridView, string columnText)
{
var i = 0;
var specificSearch = false;
float leftBorder = 0;
float rightBorder = 0;
if (columnText.Contains(@"\"))
{
var searchedText = columnText.Split(new char[] { '\\' });
var commonHeaderPresenter = radGridView.FindElement(xamlTag: "CommonHeaderPresenter");
var commonColumnHeaders = commonHeaderPresenter.FindElements(xamlTag: "CommonColumnHeader", textContent: searchedText[0]);
if (commonColumnHeaders.Count == 0)
throw new Exception("...");
specificSearch = true;
leftBorder = commonColumnHeaders[0].GetRectangle().X;
rightBorder = commonColumnHeaders[0].GetRectangle().X + commonColumnHeaders[0].GetRectangle().Width;
columnText = searchedText[1];
}
foreach (var headerCell in radGridView.HeaderRow.HeaderCells)
{
if (headerCell.Text.Equals(columnText))
{
if (!specificSearch)
return radGridView.HeaderRow.HeaderCells.Count - 1 - i;
var middleLine = (headerCell.GetRectangle().Width/2) + headerCell.GetRectangle().X;
if (middleLine > leftBorder && middleLine < rightBorder)
return radGridView.HeaderRow.HeaderCells.Count - 1 - i;
}
i++;
}
return -1;
}
I decided to identify the column and its group based on the screen coordinates of the elements. It works perfectly.
Thank you.
Kind Regards,
Stanislav Hordiyenko
