Set filter on enum field does not work

Hello, I have a data grid with a GridViewComboBoxColumn bound to an field which is an enumeration. I use DataSource and properties 'ValueMember' and 'DisplayMember' to map enum values to readable strings. When I try to set a filter on the column an exception ist thrown 'column <x> not found' ( where x is the string represantation of the enum value )

Here is an example: If I then try to set filter to EProductType.Hard => EvaluateExcetion is thrown 'column [Hard] not found'
First FilterConditionType is 'NoFilter', when I select condition exception occurs

    
            public enum EProductType 
        
                { 
        
                    None = 0, 
        
                    Soft = 1, 
        
                    Hard = 2 
        
                } 
        
                class Product 
        
                { 
        
                    EProductType _productType; 
        
                    public EProductType ProductType 
        
                    { 
        
                        get { return _productType; } 
        
                        set { _productType = value; } 
        
                    } 
        
                    string _key; 
        
                    public string Key 
        
                    { 
        
                        get { return _key; } 
        
                        set { _key = value; } 
        
                    } 
        
                    string _name; 
        
                    public string Name 
        
                    { 
        
                        get { return _name; } 
        
                        set { _name = value; } 
        
                    } 
        
                } 
        
            private void AddMapping() 
        
            { 
        
            IList<ValueMapping> mappings = new List<ValueMapping>(); 
        
                        mappings.Add(new ValueMapping(EProductType.None, "")); 
        
                        mappings.Add(new ValueMapping(EProductType.Hard, "Hardware")); 
        
                        mappings.Add(new ValueMapping(EProductType.Soft, "Software"));

                { 
        
                    public ValueMapping(object value, string displayMember)

Export to ...

Would be great if you add the column selection option in future.
If a bitmap column - we don't need Type name instead.
Just my desire.

RadGridView bound to BindingList not updating

Hi All,

I have a RadGridView bound to a BindingList that does not update when I change my BindingList. Basically, I am traversing my list with LINQ and updating some fields, but these fields are not updating in the RadGridView.

Hers is my code:

var mAgentsInList = from a in cAgentList

where a.AgentId.ToLower() == p_AgentId.ToLower()

select a;

foreach (DTLAgent feAgentToUpdate in mAgentsInList)

{

feAgentToUpdate.OutboundCalls = 99;

if (p_Direction.ToUpper() == "IN")

{

feAgentToUpdate.Direction = "In";

}

The only way I can reflect these changes is by calling:

grdAgents.MasterTemplate.Refresh();

However, this grid has about 300 Agents, and whenever I call this Refresh, the grid scrolls back to the top - which is not something that works for me.

Thanks in advance for any help!

F1 KeyDown Event

Hello,

I can't seem to trap any Function keys while editing a cell on the radGridView. Could you provide any clues where I am going wrong? I have practically copied the code from your help documentation. If I press Ctrl+L then all works fine.
