How to find the Column Index By Name in an ASP.Net DataGrid

Howdy All,

I am wondering if there is a way to find the column index by the header
name. What I am trying to get away from is using a hardcoded number in
the ItemDataBound event. Something like this:

private void grdTestScores_I temDataBound(ob ject sender,
System.Web.UI.W ebControls.Data GridItemEventAr gs e)
{
DataRowView drvData = (DataRowView)e. Item.DataItem;
Button btnDelete;

if ((e.Item.ItemTy pe == ListItemType.It em) ||
(e.Item.ItemTyp e == ListItemType.Al ternatingItem))
{
btnDelete = (Button)e.Item. Cells[16].Controls[0];

if (btnDelete.Comm andName == "Delete")
{
btnDelete.Attri butes.Ad("oncli ck", "return ConfirmDelete() ;");
}

}
....

I don't want to hardcode the column number 16 in the above example.

Thanks in advance.

If the columns are not auto-generated, you can use datagrid Columns
collection. Write a utility function that will take a column name as a
parameter, loop through Columns collection, find a column with matching
name, get it's index and return Cells element with the same index.

Hi, I have a datagrid bound to a datatable. Now if I sort the datagrid by clicking on one of the column heads I can no longer use the index in the datagrid to find the corresponding row in the datagrid. How can I find out the new (sorted) index if I know the row in the datatable? kind regards

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
