Server side button events and command name

[Jaymie]

The documentation for the toolbar is shocking...

I have a toolbar on a page which looks like:

<telerik:RadToolBar ID="RadToolBar1" runat="server" Skin="Black" Style="width: 100%;">
<CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
    <Items>
        <telerik:RadToolBarButton runat="server" Text="Bold" AccessKey="b" ToolTip="Bold (Alt+B)" CommandName="Bold" CheckOnClick="true" AllowSelfUnCheck="true" Group="Bold" />
        <telerik:RadToolBarButton runat="server" Text="Underline" AccessKey="u" ToolTip="Underline (Alt+U)" CommandName="Underline" CheckOnClick="true" AllowSelfUnCheck="true" Group="Underline" />
        <telerik:RadToolBarButton runat="server" Text="Italic" AccessKey="i" ToolTip="Italic (Alt+I)" CommandName="Italic" CheckOnClick="true" AllowSelfUnCheck="true" Group="Italic" />
        <telerik:RadToolBarButton runat="server" Text="Quote" AccessKey="q" ToolTip="Quote (Alt+Q)" CommandName="Quote" CheckOnClick="true" AllowSelfUnCheck="true" Group="Quote" />
        <telerik:RadToolBarButton runat="server" Text="Code" AccessKey="c" ToolTip="Code (Alt+C)" CommandName="Code" CheckOnClick="true" AllowSelfUnCheck="true" Group="Code" />
        <telerik:RadToolBarButton runat="server" Text="Image" AccessKey="m" ToolTip="Image (Alt+M)" CommandName="Image" CheckOnClick="true" AllowSelfUnCheck="true" Group="Image" />
        <telerik:RadToolBarButton runat="server" Text="Link" AccessKey="l" ToolTip="Link (Alt+L)" CommandName="Link" CheckOnClick="true" AllowSelfUnCheck="true" Group="Link" />
        <telerik:RadToolBarButton runat="server" Text="Item" AccessKey="t" ToolTip="Item Links (Alt+T)" CommandName="Item" CheckOnClick="true" AllowSelfUnCheck="true" Group="Item" />
        <telerik:RadToolBarButton runat="server" IsSeparator="True" />
        <telerik:RadToolBarDropDown runat="server" Text="Size">
            <Buttons>
                <telerik:RadToolBarButton runat="server" Text="Smallest" />
                <telerik:RadToolBarButton runat="server" Text="Small" />
                <telerik:RadToolBarButton runat="server" Text="Normal" />
                <telerik:RadToolBarButton runat="server" Text="Large" />
                <telerik:RadToolBarButton runat="server" Text="Largest" />
            </Buttons>
        </telerik:RadToolBarDropDown>
        <telerik:RadToolBarDropDown runat="server" Text="Color">
            <Buttons>
                <telerik:RadToolBarButton runat="server" Text="Dark Red" />
                <telerik:RadToolBarButton runat="server" Text="Red" />
                <telerik:RadToolBarButton runat="server" Text="Orange" />
                <telerik:RadToolBarButton runat="server" Text="Brown" />
                <telerik:RadToolBarButton runat="server" Text="Yellow" />
                <telerik:RadToolBarButton runat="server" Text="Green" />
                <telerik:RadToolBarButton runat="server" Text="Olive" />
                <telerik:RadToolBarButton runat="server" Text="Cyan" />
                <telerik:RadToolBarButton runat="server" Text="Blue" />
                <telerik:RadToolBarButton runat="server" Text="Dark Blue" />
                <telerik:RadToolBarButton runat="server" Text="Violet" />
                <telerik:RadToolBarButton runat="server" Text="White" />
                <telerik:RadToolBarButton runat="server" Text="Black" />
            </Buttons>
        </telerik:RadToolBarDropDown>
    </Items>
</telerik:RadToolBar>

As you can see, The first few buttons are toggle buttons.
Now, in my code I have:

    Protected Sub RadToolBar1_ButtonClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadToolBarEventArgs) Handles RadToolBar1.ButtonClick
        ' Create our Variables
        Dim sCommand As String = e.Item.Text

        ' Select Case
        Select Case sCommand
            Case "Bold"
                ' Output the button text
                Body.Text = sCommand
        End Select
    End Sub

I would like to access other properties, for me the text property isn't enough. I need (or would like) the CommandName and also to check the state of the button, i.e. is it toggled on or off.
I don't want to have to do this clientside.

Can this be done?

Hi Jaymie,

Thank you for your feedback. Your point is well taken and we will update the documentation as per your suggestion.

If you need to access button properties from server side, you have to explicitly cast e.Item to RadToolBarButton type. Here is an example:

Protected Sub RadToolBar1_ButtonClick(sender As Object, e As Telerik.Web.UI.RadToolBarEventArgs)
    Literal1.Text = [String].Empty
    Dim btn As RadToolBarButton = TryCast(e.Item, RadToolBarButton)
    Literal1.Text += "Command name: " + btn.CommandName.ToString() + "<br/>"
    Literal1.Text += "Checked: " + btn.Checked.ToString()
End Sub

All the best,
Peter
