Based on past issue, you could try setting the ResultBoxWindowType property under LayoutSettings to normal in order to resolve the issue.

If the suggestion does not work, we will need the complete HTML structure of the page in order to analyse the issue further, preferably a simple runnable sample.

When I set the ResultBoxWindowType to normal it has a problem rendering when used with panes.  The attached picture is before attempting to display it in SharePoint.

Thanks,

Testing the scenario using a simple test page on my environment does not reproduce the same issue. In my sample, the WebCombo result box will show without overlapping the content on the left. In order to achieve the result similar to your screenshot I have to use the AdjustResultBoxLeft property. Attached is the sample page I used to test the scenario.

Have you used the latest WebDesktop 3 and WebCombo 4, build 312 and build 220 respectively?

Glenn;

The builds that I have are 310 for Desktop and 220 for WebCombo.  I don't see 312 in the list of builds on the Developer site.  Here is the code that I am using:

WebCombo combo = new WebCombo("WebCombo1");
            combo.Width = Unit.Pixel(166);
            combo.Height = Unit.Pixel(20);
            combo.MultipleSelectionSettings.Enabled = true;
            combo.UseDefaultStyle = true;
            combo.LayoutSettings.TextBoxMode = TextboxMode.ReadOnly;
            combo.LayoutSettings.ResultBoxWindowType = ISNet.WebUI.DisplayType.Normal;
            combo.Style["Position"] = "Absolute";
            combo.Style["Top"] = "25px";
            combo.Style["Left"] = "5px";

I still could not replicate the issue using the property you provided, and I believe the WebDesktop 3 build 312 is available on the WebUI Studio 2010 R1 SP1.

I have some workaround I could suggest based on the screenshot you provided. However without being able to replicate the issue on my environment I could not test the workaround myself.

In your PopUp ResultBoxWindowType solution, you could use the AdjustResultBoxLeft property and AdjustResultBoxTop property under LayoutSettings to manually modify the result box position.

In your Normal ResultBoxWindowType solution, it seems the z-index on the left pane control has greater value compared to the z-index of the WebCombo result box. Try increasing the z-Index value in the result box or decrease the z-index value in your left pane control.
