Sorry if I was not clear initially. What i want is for them to be able to select something from the drop down but not be able to edit the text in the row. For example if they select "Foo" from the drop down, they should not be able to backspace it and type "bar", they should either stick with "Foo" or select something new from the UltraDropDown.

This is what is Happening, Where I typed "EDIT" I wish to not be able to type at all, bnut only allow selecting an option from the dropdown.

This is what the cell looks like after selecting a value. Editable

I have what I want working on a UltraComboEditor on another part of my page outside of the grid. It looks like this after selecting a value. Un-Editable

I have tried this in my Initializelayout:

UltraGrid1.DisplayLayout.bands("Bottom").Columns("Values").Style = UltraWinGrid.ColumnStyle.DropDownList 

I think the issue might be that not every cell in my "Values" Column has a UltraDropDown bound to it.

Okay. That's very easy.

grid.DisplayLayout.Bands[1].Columns["Values"].Style = ColumnStyle.DropDownList;

If you have to do this for some cells and not other, then use the InitializeRow event and set the Style property on the Cell to DropDownList. Presumably you are already using InitializeRow to apply the dropdown to the cell, so you would set the Style on the cell at the same time. 

I was actually setting the drop down when creating each row. The data I am being passed is parsed into arrays from XML files. This results in me setting each cell one at a time. Code looks something like this

 

reportName = UltraGrid1.DisplayLayout.Bands("Top").AddNew() 'add top level row to grid
reportName.Cells("Report").Value = array3(1, i) 'report name to new row
For k = 1 To array3(3, i) 'loop for amount set in parent array
parameterName = UltraGrid1.DisplayLayout.Bands("Bottom").AddNew() 'add bottom level row to grid    
parameterName.Cells("List").Value = array1(7, counter)
If Not parameterName.Cells("List").Value = "" Then        
 parameterName.Cells("Values").ValueList = UltraDropDown1
 parameterName.Cells("Values").Value = array1(8, counter)        
parameterName.Cells("Values").Style = UltraWinGrid.ColumnStyle.DropDownList    
 Else        
 parameterName.Cells("Values").Value = parameterName.Cells("HiddenVal").Value 'set for textbox        
parameterName.Cells("Values").Style = UltraWinGrid.ColumnStyle.Edit    
End If                
Next

 When I tried to write a InitializeRow event i was caught with "ArgumentException: Key not found: 'List' Parameter name: key"

Private Sub UltraGrid1_InitializeRow(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.InitializeRowEventArgs) Handles ultraGrid1.InitializeRow
If e.Row.Cells("List").Value = "" Then            
 UltraGrid1.DisplayLayout.Bands("Bottom").Columns("Values").Style = UltraWinGrid.ColumnStyle.DropDownList         
End If
End Sub

Thank yu for your help, i ended up using

I also tried this with zero errors but it did not work:

    Private Sub UltraGrid1_InitializeRow(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.InitializeRowEventArgs) Handles UltraGrid1.InitializeRow         
If e.Row.Band Is Me.UltraGrid1.DisplayLayout.Bands("Bottom") Then             
If e.Row.Cells("List").Value Is "" Then                 
e.Row.Cells("Values").Style = UltraWinGrid.ColumnStyle.DropDownList             
End If         
End If     
End Sub
