  We are having an issue with the AddItem() method that is causing an exception to be thrown in our project. If we load data into a flex grid, edit one of the rows, press enter, then clear the data and call the AddItem() method, it will add two rows instead of one. However, if you don’t edit any of the rows before clearing the data, it will add one row like we expect it to. I’ve attached a sample project that will demonstrate this behavior.

  Hi Anthony,

  Thanks a lot for sharing the sample application.
  
  However, could you elaborate a bit about how you are clearing the data, once the data is loaded in C1FlexGrid, since there are only Add Row, Undo and LoadData options available in your application UI.
  
  And loading data in grid, editing any row, pressing enter and Adding a new row does not create multiple rows at our end. So, could you please share your build version you are using?

  Thanks,

  I’ve attached a short video demonstrating the behavior. It’s a little easier than explaining. If you have more questions afterwards, I will do my best to explain.

  And I’m using version 4.0.20172.271, Runtime Version 4.0.30319 of the FlexGrid assembly.

  Hi,

  Thank you for attaching a video showing the issue.
  
  We could observe the same at our end and it is an issue with the control. Hence the same has been escalated to the Development team for fix {Tracking ID: 293038}.
  
  We would update you once it is fixed.

  Hi,
  
  For meantime, you can modify your AddRow() method as:

   
                 private void AddRow()
          {
              C1FlexGrid g = _dataGrid;
              if ((g.DataSource as DataTable) == null)
              {
                  g.AddItem("");
              }
              else
              {
                  (g.DataSource as DataTable).Rows.Add((g.DataSource as DataTable).NewRow());
              }            
          }
  
  

  Hope, it will help you.

  Thanks,

  Hello,

  It helped with the sample application, but unfortunately not in the production code. I will wait for the update.

  Thank you!
