update/insert button

[Catalina]

I have this on my RagGrid Edit FormTemplate:              

       <telerik:RadButton ID="RadBtnUpdate" runat="server" Text="Update" CommandName="Update"
                            Visible='<%# !(DataItem is Telerik.Web.UI.GridInsertionObject) %>' CssClass="ComandButton">
                        </telerik:RadButton>
                       
       <telerik:RadButton ID="RadBtnInsert" runat="server" Text="Insert" CommandName="PerformInsert"
                            Visible='<%# DataItem is Telerik.Web.UI.GridInsertionObject %>' CssClass="ComandButton">
                        </telerik:RadButton>

When i "press" insert my "update button" is visible, not "insert button". (on edit appears update button, which is ok)
Any ideea why this?

Hello Catalina,

Try modifying your code as shown below.
aspx:

<FormTemplate>
    <telerik:RadButton ID="RadBtnUpdate" runat="server" Text="Update" CommandName="Update" Visible='<%# !(Container is Telerik.Web.UI.GridEditFormInsertItem) %>' CssClass="ComandButton"></telerik:RadButton>
     <telerik:RadButton ID="RadBtnInsert" runat="server" Text="Insert" CommandName="PerformInsert" Visible='<%# Container is Telerik.Web.UI.GridEditFormInsertItem %>' CssClass="ComandButton"></telerik:RadButton>
</FormTemplate>

Thanks,
Shinu.
