Hi,
I'm using a radcombobox with checkboxes and need to set the initial text to blank.
I have tried different methods but nothing helps.
I have this code:
IList types = EnumHelper.ToLocalizedList(typeof(FaultyType), Resources.resources.ResourceManager); 
            foreach (KeyValuePair<Enum, string> keyval in types) 
            { 
                RadComboBoxItem item = new RadComboBoxItem(); 
                item.Text = keyval.Value; 
                item.Value = keyval.Key.ToString(); 
                radComboBoxFaultyTypes.Items.Add(item); 
                item.DataBind(); 
            } 
 

 <telerik:RadComboBox ID="radComboBoxFaultyTypes" runat="server"  
                            onitemdatabound="radComboBoxFaultyTypes_ItemDataBound"
                         <ItemTemplate> 
                            <div onclick="StopPropagation(event); SetFaultyTypesText();" class="combo-item-template"
                                <asp:CheckBox runat="server" ID="chk1" /> 
                                <asp:Label runat="server" ID="labelFaultyTypeName" AssociatedControlID="chk1" Text='<%# DataBinder.Eval(Container, "Text") %>' > </asp:Label> 
                            </div> 
                        </ItemTemplate> 
                        </telerik:RadComboBox> 

With this code the first elements text is set as initial text.
I want it to be blank or to be set like: "Please choose".
I could solve it be add a item with blank text and value but in that case I need to hide the checkbox in some way on that item.
 
Regards,
Mattias

Hello Mattias,

Please look at the end of this help topic.

In your case you should check if the Container.DataItem is null in the Text property of the Label in ItemTemplate.

Let me know if you still have any questions.

Kind regards,
