How can I have a custom toolbar button execute server-side code?

[Ross Presser]

When the user clicks this button on the toolbar, I want to trigger some server side code which will convert from "HTML scripting" to "VB scripting" in our system.  (Neither of those things is exactly what you think it is. ) I have created the toolbar button:

    Private Sub formatFieldScriptingHtml(ByRef re As RadEditor, ByVal textdir As eDocLibrary.eDocFieldInfo.textDirection)

        re.ToolsFile = "~/include/FieldScriptingToolsFile.xml"
        're.DisableFilter(EditorFilters.IndentHTMLContent)
        re.ContentFilters = EditorFilters.None

        'This button needs to be added in codebehind, because it gets localized button text
        'The other buttons are standard toolbar buttons that get localized by Telerik
        Dim toVB = New Telerik.Web.UI.EditorTool
        toVB.Name = "toVB"
        toVB.Text = Resources.Main.ConvertToVbButtonText '"Convert to VB", localized
        toVB.ShowIcon = False
        toVB.ShowText = True
        re.Tools(0).Tools.Add(toVB)
' ... omitted code
End Sub

And I've put this in a RadScriptBlock, though I'm not sure it's working:

<telerik:RadScriptBlock>
    <script>
        Telerik.Web.UI.Editor.CommandList["toVB"] = function (commandName, editor, args) {
            var ajaxManager = $find("<%= AjaxManager.ClientID%>");
            ajaxManager.ajaxRequest("toVB");
        }
    </script>
</telerik:RadScriptBlock>

Will this look for a server side function called "toVB"? Or what exactly do I have to do?

Hello Ross,

Using the RadAjaxManager to invoke a code behind logic should be further implemented by attaching a server-side OnAjaxRequest event handler and handle the passed arguments in the implemented VB method.

You can find a proper example in this help article by following Example 1 and 2.
