Hi,

I try to handle the error in delete action, when clicked delete button, but i can't handle radgrid_itemDeleted, visual studio shows the error.

for example

<telerik:RadPanelBar ID="RadPanelBar1" runat="server" ExpandMode="SingleExpandedItem"

Width="1102px" Skin="Vista" AllowCollapseAllItems="true" >

<CollapseAnimation Type="None"></CollapseAnimation>

<Items>

<telerik:RadPanelItem runat="server" Text="Objectives Parameters" Expanded="true">

<Items>

<telerik:RadPanelItem Text="" Value="PanelItemObjParameters">

<ItemTemplate>

<telerik:RadGrid ID="RadGrid1" runat="server" AllowAutomaticDeletes="True" AllowAutomaticInserts="True"

AllowAutomaticUpdates="True" AllowPaging="True" AutoGenerateColumns="False" AutoGenerateDeleteColumn="True"

AutoGenerateEditColumn="True" CellSpacing="0" DataSourceID="ObjectiveParameterDataSource"

GridLines="None" >

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

<MasterTableView DataKeyNames="objective_parameter_id" DataSourceID="ObjectiveParameterDataSource"

CommandItemDisplay="Top">

<CommandItemSettings ExportToPdfText="Export to PDF" />

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="objective_parameter_id" DataType="System.Int32"

FilterControlAltText="Filter objective_parameter_id column" HeaderText="Id" ReadOnly="True"

SortExpression="objective_parameter_id" UniqueName="objective_parameter_id">

</telerik:GridBoundColumn>

<telerik:GridDropDownColumn DataField="objective_id" DataSourceID="ObjectiveDataSource"

HeaderText="Objective" ListTextField="objective_name" ListValueField="objective_id"

UniqueName="objective_id" ColumnEditorID="GridDropDownColumnEditorAdm1">

</telerik:GridDropDownColumn>

<telerik:GridTemplateColumn DataField="field_name" FilterControlAltText="Filter field_name column"

HeaderText="Field Name" SortExpression="field_name" UniqueName="field_name">

<EditItemTemplate>

<asp:TextBox ID="field_nameTextBox" runat="server" Text='<%# Bind("field_name") %>'></asp:TextBox>

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="field_nameTextBox"

ErrorMessage="*"></asp:RequiredFieldValidator>

</EditItemTemplate>

<ItemTemplate>

<asp:Label ID="field_nameLabel" runat="server" Text='<%# Eval("field_name") %>'></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False">

</FilterMenu>

</telerik:RadGrid>

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

And code behind is: the error is not recognized the handles RadGrid1.

Protected Sub RadGrid1_ItemDeleted(ByVal source As Object, ByVal e As Telerik.Web.UI.GridDeletedEventArgs) Handles RadGrid1.ItemDeleted

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim id As String = item.GetDataKeyValue("objective_parameter_id").ToString()

If Not e.Exception Is Nothing Then

e.ExceptionHandled = True

SetMessage("Objective Type with ID " + id + " cannot be deleted. Reason: " + e.Exception.Message)

Else

SetMessage("Objective Type with ID " + id + " is deleted!")

End If

End Sub

Can help me?
