    I am struggling with how to pass a context variable to the insert logic in a user control edit form when Add a new Row is selected in a grid. The example I'm modelling this after is here:

    However on the DataBinding event of the user control for GridInsertionObject, I need to get one variable from the parent form, which is the ID of a row in a related table, which is required on insert to tie the inserted row to its parent. I've tried the mechanism here:

    but that doesn't work. In the end, I store the ID I need in a session variable, but I'm not happy with that approach. Is there a simple way to do what I need to do?

    Thanks, Steve

    Hi neebs,

    You can use RadGrid's ItemCreated or ItemDataBound event to reference the user control by ID and pass it any value you need:

    protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
        if (e.Item is GridEditFormInsertItem && e.Item.IsInEditMode)
            GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;
            Control editFormControl = insertItem.FindControl(GridEditFormItem.EditFormUserControlID);
            //editFormControl now references your user control
            //you can pass it any value you need here
