Hello,

I'm afraid that WebCombo 2.0 has now been discontinued for several years and there are not going to be any further updates for it. We have introduced WebCombo 4.0 that has been enhanced to provide more powerful features to implement user scenario without any hassle.

However, I have attached a sample file that used WebCombo 4.0 for your reference.

By default, WebCombo only retrieves value in DataTextField and DataValueField. By using OnAfterItemSelected Client-side event, you can configure WebCombo to retrieve the values in each column when you are in multiple columns mode.

Use the following Javascript code to retrieve values in each column:

function WebCombo1_OnAfterItemSelected(controlId)
{
   var WebCombo1 = ISGetObject(controlId);
   var SelectedRow = WebCombo1.GetSelectedRow();
   var CellLength = SelectedRow.cells.length;

   for (var i = 0; i < CellLength; i++) 
   {
      alert(SelectedRow.cells[i].innerText);
   }
   return true;
}

Hope this helps. Thank you.
