Q: datagrid values with column name

[Guest]

Hello,
string colVal =((TextBox)e.Item.Cells.Controls[0]).Text;

this is how I reach column value in a grid:
how can I reach with the column name?
some value should be int, some date, how should I read them?
Thanks,
Jim.

Make a simple utility function that will take a column name as a parameter,
loop through the Columns collection and return the index of the column with
matching name.

C#:
static public System.Web.UI.WebControls.TableCell CellByName
(System.Web.UI.WebControls.DataGridItem item, string name)
{
System.Web.UI.WebControls.DataGrid grid = item.Parent.Parent as
System.Web.UI.WebControls.DataGrid;
for (int col = 0; col < item.Cells.Count; col++)
if (grid.Columns[col].HeaderText == name)
return item.Cells[col];
// not found
return null;
}

Hi Jim:

You can't reach the control by column name, but you could use
FindControl and fetch what you need with the Control ID. See:
http://odetocode.com/Articles/116.aspx

Also, you can look at the Convert class to convert objects into
DateTime objects and such.

HTH,
