Error on insert

[Neil]

I'm using a Prometheus RadGrid that's bound to an IList, and I'm having some trouble with inserts. When I click the Add button, I get an exception:

DataBinding: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'PhoneType'.

The error occurs as soon as I press the Add button, before the table shows any insertion controls. As far as I know, I'm not missing any relevant events, but I can't seem to figure out what I'm doing wrong. My table is declared like this:

    <telerik:RadGrid runat="server" ID="phoneGrid" AutoGenerateColumns="false" >
        <MasterTableView CommandItemDisplay="Bottom">
            <Columns>
                <telerik:GridEditCommandColumn UniqueName="EditCommandColumn" />
                <telerik:GridBoundColumn DataField="ContactPhoneid" Visible="false" ReadOnly="true" />
                <telerik:GridDropDownColumn DataField="PhoneType.PhoneTypeName" HeaderText="Type" ListTextField="PhoneTypeName" ListValueField="PhoneTypeid" DataSourceID="phoneTypeSource" />
                <telerik:GridBoundColumn DataField="Phone.PhoneNumber" HeaderText="Phone Number" MaxLength="50" />
                <telerik:GridBoundColumn DataField="Phone.PhoneExtension" HeaderText="Extension" MaxLength="10" />
                <telerik:GridBoundColumn DataField="Phone.PhoneDesc" HeaderText="Description" MaxLength="50" />
                <telerik:GridButtonColumn ButtonType="LinkButton" Text="Delete" CommandName="Delete" ConfirmText="Are you sure you want to delete this entry?" />
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>

I'm catching NeedDataSource, ItemCommand, and ItemInserted. Am I missing something, or is there a bug with object binding and subobjects?

Hello Ralph,

Unfortunately, this scenario is not supported for GridDropDownColumn. The workaround is to use GridTemplateColumn with a DropDownList in EditItemTemplate.

Please, accept our apologies for the inconvenience caused.

Kind regards,

Hi Ves,

I too am facing the same problem as Ralph.You mention that this scenario is not supported for GridDropDownColumn. Is is not supported "for the moment" and will be in future releases or is it not supported period?

Thanks for the information,

Dominic.

I am still having this issue I noticed that on my insertion when my result set comes back as null this happens if there is a fix out there where can i find it. Thanks

I don't know if it matters but i am using a grid as a user control and the edit form is also a user control and when i have a empty dataset the insert blows up  and this is the same with all insert that are created in this fashion

Let me guess, you are using a collection of custom object, maybe with nested sub objects? In such case you should do something like this:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
   if (e.CommandName == RadGrid.InitInsertCommandName)
   {
       e.Canceled = true;
       e.Item.OwnerTableView.InsertItem(new MyCustomEntity());
   }
}

This will pass a instance of your custom object to grid's insert form ensuring that all fields are there.

hi BaiH,
ur solution works perfectly excepts when the object includes a foreign key, i get this error:
Sys.WebForms.PageRequestManagerServerErrorException: Selection out of range
Parameter name: value

here is my code

        If e.CommandName = RadGrid.InitInsertCommandName Then
            e.Canceled = True
            e.Item.OwnerTableView.InsertItem(New City())
        End If

object city includes countryID as a foreign key

any ideas?
thnx in advance

BH - you saved my day. I am using nested objects and it worked. Thank you!
