Make field enterable in Hierachy PopUp

[Eric Turner]

I need to disable and enable a field in a popup edit form depending on edit or insert mode.  The grid has a MasterTableView and One Detail Table.  When I expand the MasterTableView, the Detail Table has a command Item Insert link along with edit and delete buttons.  I tried to do this in the RadGrid1_ItemCommand routine when the command is "InitInsert" but I cannot get a handle on the field I need.  How can I do this?

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
        {
            if ("Detail".Equals(e.Item.OwnerTableView.Name))
            {

                if ("InitInsert".Equals(e.CommandName))
                {
                    (e.Item as GridEditableItem)["PackageName"].Enabled = true;
                }
            }
        }

        <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1"

let me ask this another way.  I have an hierarchical grid that has an insert link on the detail gridview.  When I click the insert link I have editing set as "popup".  There are certain fields that show on the grid that do not show in the popup but do show in the grid because the readonly property is true. I want to change the readonly property to false in this instance but leave it false when going into edit mode. Everyway I have tried to do this throws a null reference error..Can anyone help a rookie?

Hello Eric Turner,

I would suggest that you review the following help article:

Different edit/insert forms with auto-generated edit form

You might need to modify the code to ensure that your logic is applied to the detail table only.

I hope this helps,
