Hi I have a gridview that has 1 row of data. I am trying to set the values
of dropdown boxes for each data row based on the data I have binded to the
grid but for some reason when I use the following below the rows are 0 so the
foreach is skipped.
gridview_RowDataBound()
{
foreach (GridViewRow dr in gridview.Rows)
}
Thanks.

The RowDataBound event occurs when each row *individually* is added to the
GridView allowing you to manipulate the row's data and controls in
isolation.

E.g. if you have a DropDownList in the first cell of the GridView, you would
do something like:

DropDownList MyDDL = (DropDownList)e.Row.Cells[0].FindControl("MyDDL");

Then you set the properties of the MyDDL variable as required...

Thanks for the information! that seemed to work for 1 row setting
gridviewrowindex to 0. Is there an easy way to get the grid row
numberwithin the RowDataBound method as I need to set the index of the
listdisc to the gridview row number. This is inside the RowDataBound method.

DropDownList ddlcat = e.Row.Cells [1].FindControl("drdwnlistCategories") as
DropDownList;
ddlcat.SelectedValue = listdisc[gridviewrowindex].Description;

Thanks for the response. I got it working, just set a manual counter.
listdisc[gridviewrowindex].Description is just a generic list containing data
where the description is what I need to set the dropdown selected value to
for each row.
