I have a Radcombo box with check boxes this is my markup:

<telerik:RadComboBox ID="ddlSpecialty" runat="server" AutoPostBack="true" AppendDataBoundItems="true" EnableEmbeddedSkins="false" Skin="Activity" Width="185px" Height="300px" emptyMessage="Click to change Specialties" >

<asp:CheckBox ID="chkSpecialty" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow" AutoPostBack="true"></asp:CheckBox>

<asp:Label ID="lblSpecialty" runat="server" AssociatedControlID="chkSpecialty"><%#Eval("Specialty") %></asp:Label>

</ItemTemplate>

</telerik:RadComboBox>

What I can't do is this:

If one check box is selected then show that value in the radcombobox, but if more than one is selected then have the words 'Multiple Selected' be displayed.

Can anyone offer any help on this.

radgridview binding problem

hi telerik,
i am working with radgridview and come to face a strange problem with binding. as i know that the default binding mode is 'one way' and if we want to 'two way' mode we have to explicitly specify it .but in my code which i am posting here,the Daat Element column is working in two way manner without specifying it, while checkbox chkIsActive and textblock txtCategory are requiring to mention mode two way otherwise they are not working well . if i try to provide mode 'two way' to the listbox itemsource and not to its child controls then still it behave like one way. please explian me , such behaviour of controls.

<telerik:RadGridView Grid.Row="1" Grid.Column="0" x:Name="DECategoryMapping" CanUserReorderColumns="True" CanUserResizeColumns="True" CanUserSortColumns="True" AutoGenerateColumns="False" IsEnabled="True">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=DENameList}" Header="Data Element"></telerik:GridViewDataColumn>

<telerik:GridViewDataColumn UniqueName="CategoryList" Header="Category List" DataMemberBinding="{ Binding Path=DElement.Category}">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<telerik:ListBox x:Name="lstCategory" ItemsSource="{Binding Path=Category}">

<telerik:ListBox.ItemTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal">

<CheckBox x:Name="chkIsActive" IsChecked="{Binding Path=IsActive, Mode=TwoWay}"></CheckBox>

<TextBlock x:Name="txtCategory" Text="{Binding Path=CategoryName, Mode=TwoWay}"></TextBlock>

</StackPanel>

</DataTemplate>

</telerik:ListBox.ItemTemplate>

</telerik:ListBox>

</DataTemplate>

FilterTemplate + error

Hello I want to filter column in my grid with filtertempalte column including RadComboBox
the code look like this(i have already read the blogs and have seen the demos about filter template)

<telerik:GridTemplateColumn DataField="Obraz" Visible="false" Resizable="false" UniqueName="TemplateColumn"

AllowFiltering="true">

<telerik:RadComboBox ID="ComboFilterBox" runat="server" AppendDataBoundItems="true" OnSelectedIndexChanged="FilterCombo_SelectedIndexChanged" DataTextField="Obraz" DataValueField="Obraz"

OnLoad="Combo_NeedDataSource" AutoPostBack="true">

</FilterTemplate>

<asp:Image ID="Image1" runat="server" ImageUrl="<%# bind('Obraz') %>" ForeColor="White" />

</ItemTemplate>

</telerik:GridTemplateColumn>

and then in Code-Behind I have placed the function

protected

void FilterCombo_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

string filterExpression;

filterExpression =

"([Obraz] = '" + e.Value + "')";

RadGrid1.MasterTableView.FilterExpression = filterExpression;

RadGrid1.MasterTableView.Rebind();

}

and then when I change the values in combobox i get the error
Sys.WebForms.PageRequestManagerServerErrorException: Expression expected
after Rebind.

How to disable a RadDockZone

I'm using RadDockLayout control which has two zones (i.e. Zone1 and Zone2), each of which has RadDock with some content.

I want to be able to disable zone1 such that the RadDock in zone one cannot be dragged into or outside this zone, and RadDock in zone2 should not be dragged into zone since it's disabled.

I have tried to use Enabled property of RadDockZone but it does not seem to work.

How can disable a zone such that once data is displayed in the zone via RadDock cannot be manipulated by a user? Anybody??
