Drop Down Lists inside of a GridView

[kralco626]

I have a grid view and I have a drop down list in several of the cols. A couple have their own data source, and a couple are hard coded. So when I click edit the labels turn to drop down list. BUT, i need to access the drop down lists before the user edits, because I need to set the drop down lists to the current values.

For example if i select option 3, when i click edit and the drop down menu apears I want it to default to option 3. To do this I need to access these drop down lists in my code behind. How do i do this?

I have tried access them in the onediting method but the drop down lists seem to not be created yet.

Thanks for any help!

This is my code of the grid view:

<asp:GridView ID="GridView1" runat="server" Width="100%" 
        AutoGenerateColumns="False" DataSourceID="SqlDataSource1" 
        onselectedindexchanged="GridView1_SelectedIndexChanged" 
        onrowcommand = "GridView1_RowCommand" 
        OnRowUpdating = "GridView1_RowUpdating" 
        OnRowEditing = "GridView1_RowEditing" 
         >

SOLVED:

protected void GridView1_DataBound(object sender, GridViewRowEventArgs e)
    {
        GridViewRow row = e.Row;

        if ((row.RowType == DataControlRowType.DataRow) && ((row.RowState & DataControlRowState.Edit) > 0))
        {
            DropDownList ddl = row.FindControl("invld_data_reasn_id_ddl") as DropDownList;
            Label lb = row.FindControl("Label1") as Label;
