Question

I renew parameters of my DataSource for GridView on Button and loads event Page_Load()
and After it (or with it) GridView renews itself.

I need to rename Header rows but there is no event after Page Load.

more information about details here :

[On Button Click] I change DataSource and Bind it (SqlDataSource1.DataBind(); ) Then sure Page gone to Refresh elements.

[On Page_Load] GridView is changing data, but if I can’t change Headers there because it’s looking like loads after this function 🙁

[one more Button] I can add new button with a function – rename headers and it works correct everytime

    protected void Button2_Click(object sender, EventArgs e)
{
    // Stack overflow
    DataRow T;
    if (go)
        if (GridView2.HeaderRow.Cells.Count != 0)
            for (int i = 0; i < SQF.SQF.Permission.Rows.Count; i++)
            {
                T = SQF.SQF.Permission.Rows[i];
                GridView2.HeaderRow.Cells[i].Text = (string)T["Caption1"];
                WebMsgBox.Show((string)T["Caption1"]);
            }
}

Trouble : I no need one more button for it, I need to rename header rows after I click button to change Data but I have no idea where I can do it.

thank you.

Well you could use Gridview DataBound event, like that:

<asp:GridView runat="server" ID="SomeID" OnDataBound="GridVIew_OnDataBound" ... />

The DataBound event occurs right after the databinding process for that particular control has completed.
