VSTO DrawItem control not visible RRS feed

  • Question

  • Hi all,

    we have an Excel VSTO application with a taskpane containing some comboboxes, buttons and a rRchtTextbox. For the comboboxes  we use the DrawItem, for the RTB  we use onpaint to set colors/font details and so on.

    Now it works perfectly but we are having some problems with some clients( about 2 percent of our installed base), they don't see the 'DrawItem/Onpaint' controls on the screen, the rest of the controls are OK.

    I can't find any usefull info on internet, any idea?


    BTW is the .net framework version (4.0 currently used) of importance?
