How to change values in UserControl in a Cell

[Luis Guerra]

Using the RepeaterUserControl sample, how can I change the value in a textbox in the UserControl, knowing the rowIndex and colIndex of the cell hosting the UserControl?
I can figure out how to get to the UserControl in an specific cell to change values in textboxes or other controls in the UserControl.

One approach would be to change the DataSource directly instead of trying to change the DataSource through the grid.

int gridRowIndex = ???;//what ever grid row you want to set
int positionInDataTable = gridRowIndex - 1;
this.dt.Rows[positionInDataTable]["City"] = newValue; //change the city field

Making the change directly to the datasource should be immediately reflected in the grid display.
