[Borislava]

Hi Borislava,

I guess you are using a WebUserControl EditForm inside Radgrid. Please go through this Demo which shows operations performed in a RadGrid using WebUserControl form. If this doesn't help, please provide your full code snippet.

<telerik:RadGrid ID="rgGroups" ...>...
 <EditFormSettings EditFormType="Template">
            <FormTemplate>
  .....
   <uc2:Campuses runat="server" ID="Campuses" />
  <asp:TextBox......
      </FormTemplate>...
</telerik:RadGrid>

and code behind
 Private Sub rgGroups_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgGroups.ItemCreated
        If TypeOf e.Item Is GridEditableItem And e.Item.IsInEditMode Then
            If TypeOf e.Item Is GridEditFormInsertItem OrElse TypeOf e.Item Is GridDataInsertItem Then
                ' insert item
                Dim editform As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
                Dim Campuses As Campuses = CType(e.Item.FindControl("Campuses"), Campuses)
                Campuses.MakeInit(Nothing)
            Else
                ' edit item
                Dim editform As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
                Dim Campuses As Campuses = CType(e.Item.FindControl("Campuses"), Campuses)
                Campuses.MakeInit(editform.GetDataKeyValue("GroupID"))
            End If
        End If

<uc2:Campuses> is a webUser control with RadGrid which should allow to edit/add/delete:  allow to perform action while rgGroups is in edit mode .
When I am trying to add a new item in webUser control it goes  to userControl load page
but don't fire an event (Insert/update).why?

Hi Borislava,

Below is a sample code snippet that i tried which works fine at my end. With your given code its hard to identify the cause of the problem. Please try the sample code snippet, add the UserControl as follows and see if it helps, else provide your full code.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" . . .>
    <MasterTableView. . .>
        <EditFormSettings UserControlName="EditPopup.ascx" EditFormType="WebUserControl"
            EditColumn-UniqueName="EditCommandColumn1">
        </EditFormSettings>
    </MasterTableView>
</telerik:RadGrid>

ASCX:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateEditColumn="true" AutoGenerateDeleteColumn="true"
    OnInsertCommand="RadGrid1_InsertCommand">
    <MasterTableView DataKeyNames="ID" CommandItemDisplay="Top">
        <Columns>
         . . . .
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

ASCX:CS:

Protected Sub RadGrid1_InsertCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.InsertCommand
    'Code to insert
   End Sub

Here is code block for better understanding

<FormTemplate>
                       <telerik:RadTabStrip runat="server" ID="RadTabStrip1" Orientation="HorizontalTop"
                           SelectedIndex="0" MultiPageID="RadMultiPage1" CssClass="tabstrip" Skin="Default">

                             <telerik:RadTab Text="Tab2">  </telerik:RadTab>

                         <telerik:RadPageView runat="server" ID="RadPageView2">

Hi Borislava,

Please modify your btnUpdate as follows ,it should fire the Update/Insert Command events. In UserControl also add this button code for Update/Insert.

ASPX:

<asp:Button ID="btnUpdate" Text='<%# (Container is GridEditFormInsertItem) ? "Insert" : "Update" %>'
runat="server" CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>'>
</asp:Button>

Thanks,
Princy

Hello Borislava,

For your convenience I have prepared a sample page with RadGrid that uses WebUserControl within the FormTemplate that works as expected on my end. 

As a side note, if you are ajaxifying your outer grid, please remove all UpdatePanels placed in the FormTemplate or at least the one place around the Button.

Hope that helps.
