Custom Validator not invoked in RadGrid

Hi everybody,

Since RadNumericTextBoxes do not provide a build-in feature to have it as required field, we implemented a custom validator that checks for a missing value. This validator works well, if the NumericTextBox is not within a RadGrid. If we use the custom validator within a EditTemplate, it is not invoked. When we use a asp:RequiredFieldValidor instead, the validation is processed. Why is a custom validor not invoked when we click "Insert" or "Update" while a RequiredFieldValidator works correctly?

Thanks in advance
Marco

<EditFormSettings EditFormType="Template">

<EditColumn FilterControlAltText="Filter EditCommandColumn column" />

<FormTemplate>

<table cellspacing="2" cellpadding="1" border="0">

<tr>

<td>

<telerik:RadNumericTextBox ID="Amount" runat="server" DbValue='<%# Bind("Amount") %>' Width="80px" />

<asp:RequiredFieldValidator ControlToValidate="Amount" ErrorMessage="*" runat="server" Text="*" />

<asp:CustomValidator ID="Amount_Required" ClientValidationFunction="CheckNumberRequired"

ControlToValidate="Amount" runat="server" ValidateEmptyText="true" />

</td>

</tr>

RadComboBoxItem.Selected = true not working

I have a combo box that I am attempting to populate in the page_load event and want the item in the combo box that corresponds to an incoming request string member value to be selected when done. I have done this before and am not a "greenie", but I cannot get any item selected in the combo box.

The definition of the combo box is in the code block immediately below:

<telerik:RadComboBox ID="SearchCountry" TabIndex="5" style="z-index: 9000;" Width="200px" EnableEmbeddedSkins="true" Skin="Sitefinity" runat="server" Height="150px" OnClientSelectedIndexChanging="LoadSearchStateProv"></telerik:RadComboBox>

The server-side code behind code is immediately below this line:

Try

Dim reader As SqlDataReader = cmd.ExecuteReader()

Do While reader.Read()

RCBI = New RadComboBoxItem()

RCBI.Text = reader(sFieldToPopulate)

RCBI.Value = reader("CodeList")

If oValueToMatch = RCBI.Value Then

RCBI.Selected = True

End If

RadComboBox1.Items.Add(RCBI)

Loop

reader.Close()

reader = Nothing

Catch ex As Exception

Throw New ApplicationException("Error reading to populate country combo box from Select Statement=" & ComboSelectStmt & ". Code=" & ex.Message)

Finally

End Try

Can you please tell me what I am doing wrong? The combo box is being populated correctly...but no item is selected when the page_load event completes and the page is visible. Why?

Thanks in advance!

Filter grid using combo box - client side

Hi all,

I have a grid created through declarative client side binding. Everything works fine but now I have added a combox and I would like the databind function to be called again as soon as an item is selected.

There is an example in the demo but it looks like this happening on the server side. I need this to happen on the client side. Here is my code:

<%@ Page language="C#" Codebehind="Custom_DealUI.aspx.cs" AutoEventWireup="false" Inherits="KF.Crm.Web.Custom_DealUI" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<head id="Head1" runat="server">

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

<!--

function OnClientSelectedIndexChangedEventHandler(sender, args) {

//NEED TO SOMEHOW CALL THE CLIENT SIDE DATABIND FUNCTION

}

function RadGrid1_DataBinding(sender, args) {

var dataSourceLocation = args.get_location();

var selectMethodName = args.get_methodName();

var methodArguments = args.get_methodArguments();

var startRowIndexParameterName = sender.ClientSettings.DataBinding.StartRowIndexParameterName;

var maximumRowsParameterName = sender.ClientSettings.DataBinding.MaximumRowsParameterName;

var sortParameterName = sender.ClientSettings.DataBinding.SortParameterName;

var filterParameterName = sender.ClientSettings.DataBinding.FilterParameterName;

}
