Hello,
I have a very similar problem, but I tried your solution and it did not work.
I have just that blank asp.net page with a fileexplorer:
<
telerik:RadFileExplorer runat="server" ID="FileExplorer1" Width="520px" Height="520px">
<Configuration ViewPaths="~/" UploadPaths="~/" DeletePaths="~/" />
</telerik:RadFileExplorer>
In codebehind .cs file I just add a RadToolBarSplitButton to the fileexplorers toolbar and add some RadToolBarButtons to that splitbutton. I don´t want to see any (refresh-) images on these buttons. So codebehind looks like this:
FileExplorer1.InitialPath = Page.ResolveUrl("~/");
RadToolBarSplitButton radToolBarSplitButton = new RadToolBarSplitButton("Repository");
radToolBarSplitButton.Buttons.Add(new RadToolBarButton("Demo"));
radToolBarSplitButton.Buttons.Add(new RadToolBarButton("Manual"));
FileExplorer1.ToolBar.Items.Add(radToolBarSplitButton);
I tried your solution with "background-image:none;" in style part of aspx page, but nothing happened. Even if I set "background-image:test.jpg" a different image than refresh - image is not shown.
AND
As a second problem, the (refresh) image is shown in the background of the buttons text, not to it´s left. The funny thing is: This behaviour changes, if I put a RadToolBar on the page (right before the fileexplorer).
I hope you can help.
