I have one GridButtonColumn. sometimes can be empty.
Use put " " for grid cell (on grid_ItemDataBound)
works on regular base for the grid, but for my grid, I have a button in a column to open a new window using below code. As long as the new winodw pops, the white line cell comes back again
StringBuilder sbNewFileReq = new StringBuilder();
ScriptManager.RegisterStartupScript(this, GetType(), "ViewOppUpKey", sbNewFileReq.ToString(), true);
This empty cell is on my second level of the grid, when set
" and expand the grid, the empty cell no edge problem will also comes up.
If there anyway we can change css to fix the problem?
