  Hi Guys,

  Many many years ago I have a problem : how to add a tooltip to each item in the c1ComboBox. Your Guys give me a solution (https://www.grapecity.com/en/forums/winforms-edition/c1combobox-amp-tooltip-for_1) and everything works fine till I’ve updated the version. And now it is crashed.

  Could you please help me to find a new solution or please fix your bug.

  With kindly regards, Olga Sukha

  Hello Olga,

  Please try the below mentioned ways to get rid of your issue:

  1. In the “Solution explorer”, open the “References” section. In the properties of the C1 related references, there should be a property “Specific version”. This should be “false”. If it is “true”, then switch it. Rebuild the sample and see if it helps.

  2. Open the “license.licx” file in your project and check if the entries have version information. Kindly remove them. The entries present as

  C1.Win.C1Input.C1ComboBox, C1.Win.C1Input.4, Version=4.0.20173.286, Culture=neutral, PublicKeyToken=7e7ff60f0c2112sb
  

  must be replaced with

  C1.Win.C1Input.C1ComboBox, C1.Win.C1Input.4
  

  Let us know if the issue persists. Also, kindly confirm the version you are using now.

  Best Regards,
  
  Esha

  Hi Olga,
  
  Sorry, but user can’t use custom dropdown form for C1Combobox, after *.264 build.

  But, I attached workaround for this case (please, see C1ComboBoxTooltips_new.zip) and we added new enhancement request for this case.

  Best Regards,

  Hi Guys,

  Thanks for the solution, but I’m disappointed a little with

  _view = (XView)form.Controls[0].Controls[0].Controls[0];

  in the next update you’ll add one more panel at the DropDownForm and this will be crashed again ((

  With kindly regards, Olga Sukha

  Hello Olga,

  We understand your concern. Currently, we don’t have a public api to resolve this issue. However, an enhancement request for the same is raised. As of now, instead of

  _view = (XView)form.Controls[0].Controls[0].Controls[0];
  

  you can use:

  
  Control cnt = form;
  while (cnt.Controls.Count > 0 && !(cnt is XView))
  cnt = cnt.Controls[0];
  _view = (XView)cnt;
  

  Best Regards,
