Deactivate an item in a valuelist based on a tag property

Posted on 2009-05-08
Last Modified: 2012-08-14
I have some items in an Infragistics (using 2008 volume 3 WinForms) valuelist which are active and some are inactive but need to be displayed for historical records purposes.  

My ideal situation would be to display them but not select the item.  The second best scenario would be to do a strikethrough on the text of the Inactive records.

Not quite what I'm looking for.  I need to allow some ValueListItems to be selected within a ValueList, but other ValueListItems within the ValueList to be not selected.

it is difficult to enable / disable  items in the value list at run time ... change the popluating of value list logic as shown in the infragisitcs sample.

    private void PopulateSpacePortsValueList()
        if ( this.gridValueLists.DisplayLayout.ValueLists.Exists("SpacePorts") )
        ValueList objValueList = this.gridValueLists.DisplayLayout.ValueLists.Add("SpacePorts");
        DataTable ds = new SpaceFlightsData().SpacePorts;
        for ( int i = 0; i < ds.Rows.Count; i++ )
            objValueList.ValueListItems.Add((int)(ds.Rows[i].ItemArray[0]), ds.Rows[i].ItemArray[1].ToString());

The 2 valuelists is a good idea.  Just change them on the before dropdown event and set it back on the afterExitEntryMode event.
