I have two SqlDatSource 1 datasource for grid and one for ListBox.
I set up a Datakey name For the grid which will server as the parameter for the ListBox SqlDataSource.

I tried setting up the parameter for ListBox Datasource from Grid ItemDataBound but when doing Find Control method returns null.

below is my code behind

if

(e.Item is GridEditFormItem)

{

ListBox lbAllAccountNumbers = (ListBox)e.Item.FindControl("lbAllAccountNumbers");

SqlDataSource ds = (SqlDataSource)lbAllAccountNumbers.DataSource;

ds.SelectParameters[

"@LoginId"].DefaultValue = grdAffiliate.Items[e.Item.ItemIndex].OwnerTableView.DataKeyValues[e.Item.ItemIndex]["LoginId"].ToString();

lbAllAccountNumbers.DataSource = ds;

lbAllAccountNumbers.DataBind();

}

lbAllAccountNumbers  is getting null value
