I created my own Excel Addin and after clicking the button displays a Custom Task Pane on right. Everything is fine but when I run this addin in Excel 2013. This displays Custom Task Panes with slide it open.For my Addin Flashes disappear and appear. It looks like a problem with the display. Is there any solution? It looks very, very wrong.
PS. I'm sure they do not Set Custom Task Panes instance twice.
Display and hide performed using xxxxxxx.Visible = true / false;
Slide to close is Ok.
-------ThisAddIn.cs
_calcTaskPaneControl = new UI.CalcTaskPane(); _calcTaskPaneValue = this.CustomTaskPanes.Add(_calcTaskPaneControl, Common.CommonFunctions.GetLocalizeText("ThisAddIn_CalcTaskPaneTitle")); _calcTaskPaneValue.VisibleChanged += new EventHandler(CalcTaskPaneValue_VisibleChanged);
--------MainRibbon.cs
Globals.ThisAddIn.CalcTaskPane.Visible = true;
