Hi
My RadGridView has a one "GridViewDataColumn" which may contains a dynamic controls based on the data from the DataBase (CheckBox, TextBox, DateTime Picker and RadDropDownButton). (Dynamic controls are created by using CellElement)
RadComboBoxElement elem = new RadComboBoxElement();
RadGridView1.CurrentRow.Cells[0].CellElement.Children.Add(elem);
When my grid reached a vertical scrollbar area, when i do a vertical scrolling, the controls which is dynamically created getting re-painted in the different row index which is not the same as before vertical scrolling.
See the diiference in the attachment before vertical scroll and after
How to solve this issue.
Thanks
Arul

Hi Arul S V,
Thank you for contacting us.
RadGridView uses UI virtualization for its visual elements. Only the cells that are currently visible have corresponding visual elements. Upon scrolling they are reused, and this is what causes the issue in your case.
Currently we do not support this scenario out of the box, however it is possible to achieve it by using custom cell elements. You have to inherit from GridDataCellElement and use the CreateCell event to replace the default cell element. Then use the SetContentCore method to update cell content.
We plan to implement property grid control in one of our upcoming releases.
