How to get the row and column of button clicked, in the grid event handler?

Question

_{Thursday, April 29, 2010 3:45 AM}

Once the added button in grid (window control Grid, not Gridview or datagrid) is clicked, how to find which row and column the button is located in the grid event handler, like click event or some other events? Not the button click event handler

            #region Grid event handler setup
            myGrid.MouseEnter += new MouseEventHandler(myGrid_MouseEnter);
            myGrid.MouseLeave += new MouseEventHandler(myGrid_MouseLeave);
            myGrid.MouseDown += new MouseButtonEventHandler(myGrid_MouseDown);
            myGrid.MouseUp += new MouseButtonEventHandler(myGrid_MouseUp);
            #endregion
Thanks

I notice that Boyan has some solution for the button click event handler case

http://stackoverflow.com/questions/363100/in-wpf-how-can-i-determine-what-column-row-in-a-grid-a-control-is

In the Click event handler for the button you say:

int row;
Button btn = sender as Button;
if (btn != null)
{
    row = Grid.GetRow(btn); // And you have the row number...
}
else
{
    // A nasty error occurred...
}

Hello ThomasJH,
Thanks for your post.
I searched for a solution, you may have a try. Hope it helpful.

UIelement element = (UIelement) Grid.InputHitTest(e.GetPosition(Grid));
row= Grid.GetRow(element); 

For more information, you can see:

Grid.CurrentRow.RowIndex

 or

Grid.CurrentCell.RowIndex

to get the column value of the selected row:

this.theDataGridView.Rows[index ].Cells**[Index]** .Value

you would have to probably take the first index  from using my example earlier of obtaining the selected rows, something like maybe:

(untested)

DataGridViewSelectedRowCollection t = this.theDataGridView.SelectedRows;

object theValue = this.theDataGridView.Rows[t[0].Index].Cells[index ].Value;

Or:

object theValue = this.theDataGridView[columnIndex , rowIndex ].Value;

Rahul.

The problem is your using the mouse click as the event instead you should be subscribing to the CellContentClickedEvent

This is the equivalent to left mouse click but also handles keyboard or programmatic clicks. More importantly it will provide you with DataGridViewCellEventArgs which will give you the row and column of the item clicked.

  private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
  {
   int row = e.RowIndex;
   int col = e.ColumnIndex;
  }

Edit: I noticed that article was about WPF so what I said above might not be valid I haven't messed with WPF controls much yet.

Thanks.

I didn't make it clear in the original post that I am trying windows control grid, not gridview or datagrid.
