Hi Telerik Team,

I have created a RadGridView, in silverlight, with AutoGenearteColumns=False.
The data, XElement (XML format). will be fetched from a stored procedure in Sql Server 2008, using WCF service.
then i created column headers dynamicaaly, then i gave the Itemsource, which is a list(list<Dictionary<string,string>>).

The RadGridView is displaying the columns as required, except the filtering.

Version of RadGridView control is:2011.1.419.1040

Any help will be appreciated.

Hi,

 You may need to specify DataType for these columns to enable filtering.

Hi Vlad,

Still i'm failing to get the filtering of columns.

i'm creating the Column headers dynamically, by looping, based on my XML format.

when i run the application, it is showing the data correctly, and the filter icon on the headers are showing, but when i click on it, it is throwing an unhandled exception. 

Error images are in attachment, please have a look on them.

Please have a look on my code.

{
                       indexingConverter convert = new indexingConverter();

                        System.Windows.Data.Binding bind = new System.Windows.Data.Binding { Converter = convert, ConverterParameter =                         "HeaderName" };

GridViewDataColumn telerikColumn = new GridViewDataColumn();
                        telerikColumn.UniqueName"HeaderName";
                        telerikColumn.IsReadOnly = true;
                        telerikColumn.Header = "HeaderName";
                        telerikColumn.DataMemberBinding = bind;
           telerikColumn.DataType = typeof(string);
                        radGV.Columns.Add(telerikColumn);
}

                        radGV.ItemsSource = listofValues;


 class indexingConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            Dictionary<string, string> columnData = (Dictionary<string, string>)value;
            return columnData[parameter.ToString()];
        }
        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }


please help me in solving this.
