Hi Vlad,

That was a fast response :)

One minor problem - I have a check box on the form and was using

Private Sub grdUpdate_ItemCommand(ByVal source As Object, ByVal e As Telerik.WebControls.GridCommandEventArgs) Handles grdUpdate.ItemCommand

            If e.CommandName = RadGrid.InitInsertCommandName Then
                ' Set default values for check boxes
                e.Canceled = True
                Dim newValues As New System.Collections.Specialized.ListDictionary()
                newValues("DeliveryAsBefore") = False
                'Insert the item and rebind
                e.Item.OwnerTableView.InsertItem(newValues)
            End If
        End Sub

to set a default value of Unchecked.

Using grdUpdate.MasterTableView.IsItemInserted = True results in an error converting DBNull to Boolean.

If I remove the check box the error disappears. Any suggestion?

Hi Stephen,

Sorry but I am confused :(

It was from these articles that I discovered how to set the default values on insert.

My problem is - how do I show the table field original value in the edit form when the user clicks Edit. A Bind("CheckBoxField") will display the value in normal display mode and the sample code will display a new default value on Add New.

Before I tried to go into EditMode when there were no items in the table I had a Bind() in my edit form and all worked just fine. Now that I added

    If coll.Count < 1 Then
        grdUpdate.MasterTableView.IsItemInserted = True
    End If

to the NeedDataSource event I get an error. Removing the Bind() resolves the error but the original field value is not displayed.

Declan

            If e.CommandName = RadGrid.InitInsertCommandName Then
                ' Set default values for check boxes on insert

                ' cancel the default operation
                e.Canceled = True
                Dim newValues As New System.Collections.Specialized.ListDictionary()
                newValues("DeliveryAsBefore") = False
                'Insert the item and rebind
                e.Item.OwnerTableView.InsertItem(newValues)

If for example the table column value is true (checked) how do I display this in the edit form?

    <asp:CheckBox id="CheckBox1" runat="server"
    Text="Delivery as before"
        Enabled="false"
        AutoPostBack="False"
        Checked='<%# Bind("DeliveryAsBefore") %>'
        Visible="true" >
    </asp:CheckBox>
</ItemTemplate>
<EditItemTemplate>
    <asp:CheckBox id="chkDeliveryAsBefore" runat="server"
        Text="Tick here if you require Delivery as before"
        Enabled="true"
        AutoPostBack="False"
        Visible="true" >
    </asp:CheckBox>
</EditItemTemplate>
