Hi sengson,

How can I find the column index dynamically of selected Linkbutton when click on any of the link button which is created dynamically.

For the question above, I suggest you could find the cell in which selected link button located in by using link button’s parent property, the you could set it’s visible to false to hide the cell.
If you didn’t want to hide cell, would you please provide full code about the problem and display us with the result structure after you delete cell. i.e, you want do what change for the cell around the selected cell you want to delete.
Best regards
