Hi,
I am using ASP.Net RadControls -Q1 2010 for development.
I am using ColumnFilteringColumn class for filtering.
This working fine without paging, if I select any filtering and click on paging then this displays all record without filtering but just keep selection no actual filtering.

Please suggest any modification for below class for filtering.

public class CustomFilteringColumn : GridTemplateColumn  
    {  
        private GridKnownFunction gridKnownFunction;  
        /// <summary>  
        /// Get Set Filter Function  
        /// Predefined filter expression enumaration. Used by CustomFilteringColumn class.  
        /// </summary>  
        public GridKnownFunction FilterFunction  
        {  
            get { return gridKnownFunction; }  
            set { gridKnownFunction = value; }  
        }  
        private String uniqueId;  
        public String UniqueId  
        {  
            get { return uniqueId; }  
            set { uniqueId = value; }  
        }  
 
        public CustomFilteringColumn()  
        {  
            //  
            // TODO: Add constructor logic here  
            //  
        }  
        public DataTable GetDataTable(string strHeaderText)  
        {  
               return new DataTable();//external source...here  
        }  
 
        protected override void SetupFilterControls(TableCell cell)  
        {  
            base.SetupFilterControls(cell);  
            Object obj = cell.Controls[0];  
            cell.Controls.RemoveAt(0);  
            RadComboBox list = new RadComboBox();  
            list.ID = "list" + this.DataField;  
            list.Width = Unit.Percentage(100);  
            list.AutoPostBack = true;  
 
            list.ValidationGroup = this.CurrentFilterFunction.ToString();  
            list.SelectedIndexChanged += rcBox_SelectedIndexChanged;  
 
            DataTable table = GetDataTable(this.DataField);  
            DataRow row = table.NewRow();  
            row[this.DataField] = "All";  
            table.Rows.InsertAt(row, 0);  
            list.DataSource = table;  
            cell.Controls.AddAt(0, list);  
            cell.Controls.RemoveAt(1);  
            list.DataTextField = this.DataField;  
            list.DataValueField = this.DataField;  
        }  
        protected override void SetCurrentFilterValueToControl(TableCell cell)  
        {  
            base.SetCurrentFilterValueToControl(cell);  
            RadComboBox list = (RadComboBox)cell.Controls[0];  
            list.Items[0].Value = Resources.GeneralMessages.DefaultValue;  
            if (this.CurrentFilterValue != string.Empty)  
            {  
                list.SelectedValue = this.CurrentFilterValue;  
 
                //GridFilteringItem filterItem = list.NamingContainer as GridFilteringItem;  
                //filterItem.FireCommandEvent("Filter", new Pair(gridKnownFunction.ToString(), this.UniqueName));  
                rcBox_SelectedIndexChanged(list, new RadComboBoxSelectedIndexChangedEventArgs(""""""""));  
            }  
        }  
 
        protected override string GetCurrentFilterValueFromControl(TableCell cell)  
        {  
            RadComboBox list = (RadComboBox)cell.Controls[0];  
            if (list.SelectedValue == Resources.GeneralMessages.DefaultValue)  
                return String.Empty;  
            return list.SelectedValue;  
        }  
 
        private void rcBox_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)  
        {  
            GridFilteringItem filterItem = (sender as RadComboBox).NamingContainer as GridFilteringItem;  
            filterItem.FireCommandEvent("Filter"new Pair(gridKnownFunction.ToString(), this.UniqueName));  
 
        }  
 
    } 


<%@ Register TagPrefix="custom" Namespace="FilteringTemplateColumns" %> 
 
-----------------------------  
<custom:CustomFilteringColumn DataField="strCustomerTypeDefault" SortExpression="strCustomerTypeDefault" 
                                                                    HeaderText="Customer Type" FilterFunction="Contains" UniqueName="strCustomerTypeDefault">  
                                                                    <ItemTemplate> 
                                                                        <%# Eval("strCustomerTypeDefault")%> 
                                                                    </ItemTemplate> 
                                                                </custom:CustomFilteringColumn>

Hi Pavlina,
Thank you for your replay.
I have tried with your given link, but the problem not resolved in special scenario...
In normal environment it works fine, but the problem occurs only after generating local resources. If I try by just removing the resource key for grid then it works fine. But removing resource key - creates issue in localization for Command Menu -"Add new record".

Please suggest any idea to overcome this issue.

WIth Regards,
Naresh Goradara

Hi Naresh,

At this point in order to progress in the resolution of this matter it will be best if you open a regular support ticket and send us a simple working project, demonstrating the issue. Thus we could review it locally and advice you further.
