  Hello,
  
  I have a combo that I set the datasource = datatable and then set the .Splits(0).DisplayColumns(“colname”) the way I want.

  
   With c1cboVendor
          .ClearFields()
          .DataSource = GetVendorListDT()
          .DataMember = "VendorID"
          .DisplayMember = "VendorName"
  	.Splits(0).DisplayColumns("VendorName").Width = 180
          .Splits(0).DisplayColumns("Address1").Width = 120
  End With
  
  

  I do this by calling a method in my form_load event.
  
  After this I want to reload with a refreshed datatable (new rows added).
  
  I reuse the similar process as before and call the same method. Except this time I get an error because there is no Splits(0).
  
  I don’t understand why.
  
  version 4.0.20151.38
  
  Regards

  Hi Brian,

  Sorry but we can not replicate the issue at our end and we are not getting any error.
  
  Please find the attached sample which is working fine at our end and modify it accordingly replicating the issue.

  Note: When again assigning the DataSoruce to C1Combo, first set its DataSource to Nothing then assign the new DataSource.

  Mr Sharma,
  
  I disagree, actually you can replicate the issue but the solution is to do .DataSource = Nothing first.
  
  Oddly I have not had the issue with the c1flexgrid which I use much more commonly but I will see if it is benign and just do it as a matter of course.

  Thanks so much again
  
  Brian
