Hi Jonny,

You may have solved this already or not longer need a solution but I thought I would post this solution for others anyway.

I needed the same functionality, mostly becasue my web combo is using an AJAX call to populate but only on drop down and therefore the combo may not have any rows when the user enters a value.

Here's how I did it, all clientside java script:

1. create a global variable var txt = ""
2. On edit key key up of the web combo:
        function webcombo_EditKeyUp(webComboId){
            txt = document.getElementById("webcombo_input").value;
        }
3. On After Exit Edit Mode of the web grid:
 function webgrid_AfterExitEditModeHandler(gridName, cellId){

         var col = igtbl_getColumnById(cellId);
  if (col.Key == "webcombocolumn") {  

   var cell = igtbl_getCellById(cellId);

     cell.setValue(txt);
    }               

 }

Thats it. Hope it gives you what you need.

I am using a free ComboBox control for ASP.NET from MetaBuilders http://www.metabuilders.com/ and I can successfully populate a ComboBox outside of a webgrid.  How can I use a combo box on a column of the webgrid?

This is what I have attempted so far (following the way to add a WebMaskedEdit control) but failed to work.

1)  Declared a instance of the ComboBox

 2) In the IntializeLayout event, added the ComboBox to the Web Form:

If Not pForm1 Is Nothing Then

 With cboHomeOfRecord

 .Enabled = True

 .Visible = True

 .ID = "cboHomeOfRecord"

 End With

 pForm1.Controls.Add(cboHomeOfRecord)

End If

 3) In the IntializeLayout event, added the ComboBox to the Web Form:

 cboHomeOfRecord.DataSource =  (some function that returns an arryalist of objects)

4)  In IntializeLayout event, tied the ComboBox to a column of the Grid:

Any advice is much appreciated.
