Question

    gvOff.DataSource = o.ViewData(dCity.SelectedValue);
    gvOff.DataBind();
    gvOff.Columns[0].HeaderText = "ZZZZZZZZ";
    gvOff.Columns[1].HeaderText = "YYYYYYYY";
    gvOff.Columns[2].HeaderText = "XXXXXXXX";

Header count is correct.

AutoGenerateColumns: Flase/True ( i tried both)

If i remove the gvOff.Columns[index].HeaderText portions, GridView works fine, but when i put the gvOff.Columns[0].HeaderText, i get the exceptional error.

Can you please help, i couldn’t solve it. If you need further info, inform me.

EDITED:

Hold on! I commented the HeaderText portion and tested

int i = gvOffer.Columns.Count;

I found count is 0 eventhough the columns print out with DataBind()… Why?

NOTE: AutoColumn in this case is set to true. I guess i will have to edit the column
names from DataTable.

Solved …. I just changed column name using SQL Query alias then this reflected in my application. For example:

SELECT orderID AS [XXXXX], name AS [YYYYY] FROM TableName
