I put in the suggested lines, and I am still not getting the display text showing until you enter edit mode.  Then you can see the text displayed in the dropdown.  And the updates do work correctly.  I have attached a sample project, I put the script to create the simple table I used in the web.config.  I tried putting the code in various places, and now just have it in the pageload. 

This is odd .. I put the following code in the initializerow to just take care of the display myself.  Looking at debug, the first row that went thru, the value of the cell was the displaytext, in other words the string ("R" or "T") so it got an error of course comparing string to byte, the datavalue of the valuelist.  But the second row to come thru, the cell had the correct value (2 in this case, byte) . 

Dim i As Integer
For i = 0 To grid1.DisplayLayout.Bands(0).
   Columns(4).ValueList.ValueListItems.Count-1
       If e.Row.Cells(4).Value =                      
            grid1.DisplayLayout.Bands(0).Columns(4).
            ValueList.ValueListItems(i).DataValue Then
               e.Row.Cells(4).Text =                
    grid1.DisplayLayout.Bands(0).Columns(4).
                  ValueList.ValueListItems(i).DisplayText
       End If
Next

I added similar lines in the initializerow in the sample app that I uploaded and discovered each row goes thru the initializerow event 2 times.  First time the cell value is the byte datavalue and the cell text is the displaytext, but the second time the cell value and the displaytext are both set to the displaytext.

So for example, if I have a valuelist item with DataValue=1 and DisplayText = "A"

First Time:  Cell.Value = 1 and Cell.Text = "A"
Second Time: Cell.Value = "A" and Cell.Text = "A"

Dim i As Integer
For i = 0 To grid1.DisplayLayout.Bands(0).
          Columns(2).ValueList.ValueListItems.Count - 1
   If e.Row.Cells(2).Value = grid1.DisplayLayout.
              Bands(0).Columns(2).ValueList.ValueListItems(i).DataValue Then
         e.Row.Cells(2).Text = grid1.DisplayLayout.Bands(0).
         Columns(2).ValueList.ValueListItems(i).DisplayText
   End If
Next

Hi,

I'm wondering why the InitializeRow event is getting fired twice? I didn't get a chance to look at the second sample you've attached here. However, to work around the issue you are having with comparing the cell values, you can include a hidden column where the values (0,1,2 etc) are stored and depending on these values you can populate the visible column with text ('R','T' etc). The ValueList should be embedded to the visible column.

I'll give you my feedback on the code as soon as I get a chance.

Thanks

Hi,

I am joining this thread too late. But following is my approach which I generally use when I want to bind value list for any column.

I just populate a DataTable from my primary table of my value list reference column. Later I bind that table with value list of the column and set DisplayMember and ValueMember properties.

This is very simple and logical because we always need reference value from some primary data base table.

I have tested the sample with following code. The in actual program dt should be filled from primary table from database.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim dt As DataTable

        dt = New DataTable()

        dt.Columns.Add("Byte", GetType(Byte))

        dt.Columns.Add("Txt", GetType(String))

        Dim dr As DataRow

        dr = dt.NewRow()

        dr(0) = 4

        dr(1) = " "

        dt.Rows.Add(dr)

        dr = dt.NewRow()

        dr(0) = 1

        dr(1) = "A"

        dt.Rows.Add(dr)

        'Similarly add rows for B,C,D....

'dt should be filled with data from primary table

        grid1.Columns(2).AllowUpdate = Infragistics.WebUI.UltraWebGrid.AllowUpdate.Yes

        grid1.Columns(2).Type = Infragistics.WebUI.UltraWebGrid.ColumnType.DropDownList

        grid1.Columns(2).ValueList.DataSource = dt

        grid1.Columns(2).ValueList.DisplayMember = "Txt"

        grid1.Columns(2).ValueList.ValueMember = "Byte"

        grid1.Columns(2).ValueList.DataBind()

    End Sub

That works pretty good .. thanks, I'm going to do that.   I still think the other should work.

For future readers, the value display was not working because the grid thought the column type was String, bu that the Id type of the ValueList was integer...Making both types the same (Integer in this case) fixed up the issue.
