Thanks for the quick reply.

I have removed the DataMember reference, moved the logic to the InitializeLayout, and I still do not receive any info.   I also read over the documentation of valuelist member and tried setting:

c.ValueList.DataSource = cl1;

c.ValueList.DisplayMember = "Name";

c.ValueList.ValueMember = "Id";

still no luck.  I think I am probably missing some kind of setting I need to set programatically.

On a parallel note, is it possible to wire up an event on the binding of a row?  That way I can force the binding of the dropdown list manually.

 Thanks again,

Jason

Hi Vince

I have an infragistics grid which is supposed to have a dropdown bound to one of its columns. The grid has a datasource to be bound from the db.

This is what i tried. But no luck

grid.Columns.Add(columnName, columnName);

//Set the column to be a dropdownlist
UltraGridColumn Col = grid.Columns.FromKey(columnName);
Col.Type = ColumnType.DropDownList;
Col.DataType = "System.String";

ValueList ValList = grid.DisplayLayout.Bands[0].Columns.FromKey(columnName).ValueList;
ValList.DataSource = listArray;
foreach (string item in listArray)
{
ValList.ValueListItems.Add(item);
}
ValList.DataBind();

What can you do if you have to load the rows manually?

If you're adding rows to the grid manually, then you have control over when the columns and rows are added to the grid.  Whenever you do this is essentially equivalent to using the InitializeLayout and InitializeRow events.

So, whatever logic you'd normally perform during the InitializeLayout event, you should instead perform after you've added your bands and columns to the grid, and before you add the rows to the grid.

Do you allow editing on your grid?  If you don't, then you won't see a dropdown.

Is your WebGrid databound, or are you adding rows to it manually?  If you're adding rows manually, then InitializeLayout won't be raised.

You can use the server-side InitializeRow event to handle each row as the grid binds to it, but this won't help in your situation.  A ValueList can only be assigned to a column, not to individual cells in that column.  Like InitializeLayout, this event is only raised if you're data binding your grid, not when you're adding rows manually.

I'm in a similar situation where I have a grid that I'm adding rows to manually.  I have a column that has a databound valuelist, however the values from the DB never show up.  As per what you said, since the InitializeLayout event is never raised, it won't databind the valuelist. What can you do if you have to load the rows manually?

One last thought, though it's a "shot in the dark."  Try changing this line:

List<Class1> cl1 = new List<Class1>(0); 

... to this:

List<Class1> cl1 = new List<Class1>();
