In my FormTemplate I have a RadDateTimePicker that is validated using a RequiredFieldValidator. I use a custom Updatebutton to save the fields. The user is required to provide a date in the RadDateTimePicker. The validation does appear to work and the user gets an error message if they fail to provide a date. The problem is, is that the ItemCreated event on the server-side still gets fired when the user presses the Update button. Why is this happening? The grid shouldn't be performing any postbacks when a RequiredFieldValidator indicates that the user must provide input. The whole point of having the validation done on the client-side is to avoid a postback of any kind to the server. Here is the code in my FormTemplate:

    
            <FormTemplate> 
        
                <table id="tableSessionDetails" cellpadding="5px" cellspacing="0" border="0" style="width: 100%;  
        
                  margin-top: 10px; margin-left: 5px"> 
        
                  <tr> 
        
                    <td style="width: 120px">  
        
                      <asp:Label ID="lblSessionDate" runat="server" Text="Session Date:" CssClass="RadGridDetailsLabel"></asp:Label> 
        
                    </td> 
        
                    <td> 
        
                      <telerik:RadDateTimePicker ID="RadDateTimePickerSessionDate" runat="server" Skin="Sunset">  
        
                      </telerik:RadDateTimePicker> 
        
                        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="RadDateTimePickerSessionDate" 
        
                            ErrorMessage="This field is required" runat="server">  
        
                        </asp:RequiredFieldValidator> 
        
                    </td> 
        
                  </tr> 
        
                </table> 
        
                <table cellpadding="0" cellspacing="0" border="0" style="margin: 10px; width: 100%">  
        
                  <tr> 
        
                    <td align="right" style="padding-right: 20px; padding-bottom: 10px">  
        
                      <asp:ImageButton ID="imgUpdate" runat="server" ImageUrl="~/images/Update.gif" ToolTip="Update Record" 
        
                        Style="padding-right: 5px" CommandName="Update" /> 
        
                      <asp:ImageButton ID="imgCancel" runat="server" ImageUrl="~/images/Cancel.gif" ToolTip="Cancel Editing" 
        
                        CommandName="Cancel" /> 
        
                    </td> 
        
                  </tr> 
        
                </table> 
        
            </FormTemplate>

My web page was using Ajax but the Grid itself was not ajaxifying itself or the validator. I solved the problem with the following code:

    
            <telerik:AjaxSetting AjaxControlID="RadGridDataEntry">  
        
                <UpdatedControls> 
        
                  <telerik:AjaxUpdatedControl ControlID="RadGridDataEntry" /> 
        
                  <telerik:AjaxUpdatedControl ControlID="RequiredFieldValidator1" /> 
        
                </UpdatedControls> 
        
            </telerik:AjaxSetting>
