Button Settings

You can take advantage of the additional functionality that we implemented with the RadDropDownTree control by usingthe ButtonSettings described below.

Button Settings

These settings are available after the Q2 2013 release of the Telerik controls.

  • ShowCheckAll - displays a checkbox that allows checking of all checkboxes in the dropdown;

    Checkall Property

  • ShowClear - displays a button that clears the entries from the entry area.

    Clear Button

Here is sample code demonstrating how to set them inline:

ASPNET
<telerik:RadDropDownTree RenderMode="Lightweight" ID="RadDropDownTree1" runat="server" Width="250px" 
    DefaultMessage="Please select" CheckBoxes="SingleCheck"
    DataSourceID="ObjectDataSource1" DataFieldID="ID" DataFieldParentID="ParentID"
    DataTextField="Text">
    <ButtonSettings ShowCheckAll="true" ShowClear="true" />
</telerik:RadDropDownTree>
