Hi,

I followed the instructions in the link http://www.telerik.com/help/aspnet/grid/grdvalidation.html but can not get a required validator to work. I am using a form (rather than InPlace editing). I am using a RadAjaxManager that is added at runtime-don't know if this would have an affect on this. The message does not display next to the control I am validating, when I click the Update link in the form, it posts back to the server and re-displays the record before I modified the data (like remove the city to test the validator). Here's the grid html snippet:

<telerik:RadGrid ID="RadGridCageCode" runat="server" AllowFilteringByColumn="False"AllowPaging="True" AllowSorting="True" GridLines="None" Skin="Vista" EnableAJAX="True" width="60%" AllowAutomaticDeletes="True"AllowAutomaticInserts="True" AllowAutomaticUpdates="True" OnItemCommand="RadGridCageCodeLookup_ItemCommand"DataSourceID="ObjectDataSourceCageCode" PagerStyle-Mode="NextPrevNumericAndAdvanced"OnItemDeleted="RadGridCageCodeLookup_ItemDeleted" OnItemDataBound="RadGridCageCodeLookup_ItemDataBound"OnDeleteCommand="RadGridCageCodeLookup_DeleteCommand" OnItemInserted="RadGridCageCodeLookup_ItemInserted"
OnInit="RadGridCageCodeLookup_Init" OnColumnCreated="RadGridCageCodeLookup_ColumnCreated" OnInsertCommand="RadGridCageCodeLookup_InsertCommand"
OnItemUpdated="RadGridCageCodeLookup_ItemUpdated" OnUpdateCommand="RadGridCageCodeLookup_UpdateCommand" onitemcreated="RadGridCageCodeLookup_ItemCreated" >

<telerik:GridEditCommandColumn ButtonType="ImageButton" UpdateImageUrl="~\RadControls\Skins\Vista\Grid\Update.gif" EditImageUrl="~\RadControls\Skins\Vista\Grid\Edit.gif" InsertImageUrl="~\RadControls\Skins\Vista\Grid\AddRecord.gif" CancelImageUrl="~\RadControls\Skins\Vista\Grid\Cancel.gif"
UniqueName="EditCommandColumn">
</telerik:GridEditCommandColumn>
<telerik:GridBoundColumn DataField="CageCodeID" DataType="System.Int32" HeaderText="CageCodeID" ReadOnly="True" SortExpression="ID" UniqueName="CageCodeID" Visible="false">
</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="ManufacturerID" DataType="System.Int32" HeaderText="Mfg ID" SortExpression="ManufacturerID" UniqueName="ManufacturerID" visible="false" >
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="CageCode" HeaderText="Cage Code" SortExpression="CageCode" UniqueName="CageCode" >
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Address" HeaderText="Address" SortExpression="Address" UniqueName="Address">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Address2" HeaderText="Address 2" SortExpression="Address2" UniqueName="Address2" ConvertEmptyStringToNull="false" >
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="City" HeaderText="City" SortExpression="City" UniqueName="City"></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Province" HeaderText="State" SortExpression="Province" UniqueName="State">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Zip" HeaderText="Zip Code" SortExpression="Zip" UniqueName="Zip" DataFormatString="{0:#####-0000}" ></telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Phone" HeaderText="Phone Number" SortExpression="Phone" UniqueName="Phone">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn DataField="Country" HeaderText="Country" SortExpression="Country" UniqueName="Country">
</telerik:GridBoundColumn>

<telerik:GridButtonColumn ConfirmText="Are you sure you want to delete this record?" ButtonType="ImageButton" ImageUrl="~\RadControls\Skins\Vista\Grid\Delete.gif" CommandName="Delete" Text="Delete" UniqueName="DeleteColumn">
<HeaderStyle Width="20px" />
</telerik:GridButtonColumn>

</Columns>
</MasterTableView>
<ClientSettings>
<Selecting AllowRowSelect="false" />
</ClientSettings>

</telerik:RadGrid>

And the code behind to add the validator

protected void RadGridCageCodeLookup_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode)
{
GridEditableItem itemAddress = e.Item as GridEditableItem;
GridTextBoxColumnEditor editor = (GridTextBoxColumnEditor)itemAddress.EditManager.GetColumnEditor("City");
TableCell cell = (TableCell)editor.TextBoxControl.Parent;
RequiredFieldValidator validator = new RequiredFieldValidator();
editor.TextBoxControl.ID = "address_req_val";
validator.ControlToValidate = editor.TextBoxControl.ID;
validator.ErrorMessage = "Required";
validator.ID = "valAddress";
validator.EnableClientScript = true;
validator.Text = "REQUIRED!";
validator.Enabled = true;
validator.EnableViewState = true;
cell.Controls.Add(validator);

}
