i wonder if you can help

i have set up a radgrid with the google style filtering as explained here google like filter
i have combined it with some other features , but for whatever reason now it wont re-apply the filter on postback and i dont know why it has the filter items in the boxes, but is just not filtering the table anymore.

can anyone help ?

the grid is defined as
<telerik:RadGrid ID="RadGrid1" runat="server" OnColumnCreating="RadGrid1_ColumnCreating"
            OnNeedDataSource="RadGrid1_NeedDataSource" OnRowDrop="RadGrid1_RowDrop"
            AllowPaging="true" AllowSorting="true" Width="99%" PageSize="5" AutoGenerateColumns="false"
            AllowFilteringByColumn="True" AllowMultiRowSelection="true" Skin="Black" EnableLinqExpressions="false">
            <MasterTableView AllowFilteringByColumn="true" PageSize="15" EditMode="InPlace" TableLayout="Auto" >
            <PagerStyle Mode="NextPrevAndNumeric" />
            <ClientSettings AllowRowsDragDrop="True" AllowColumnsReorder="false">
                <Selecting AllowRowSelect="True" EnableDragToSelectRows="false" />

i have an ajax manager

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
            <telerik:AjaxSetting AjaxControlID="RadGrid1">
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                    <telerik:AjaxUpdatedControl ControlID="point_selection" />

and the following events defined
protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
    this.RadGrid1.DataSource = Classes.clsGlobal.FlowsData;
    this.RadGrid1.DataMember = Classes.clsGlobal.FlowsData.Tables[0].TableName;
protected void RadGrid1_ColumnCreating(object sender, GridColumnCreatingEventArgs e)
    if ((e.ColumnType == typeof(DailyFlowsFilter).Name))
        e.Column = new DailyFlowsFilter();
protected void RadGrid1_RowDrop(object sender, GridDragDropEventArgs e)
    IList<FlowItem> MyFlows = SelectedFlows;
    foreach (GridDataItem GD in e.DraggedItems)
        FlowItem NewFlow = new FlowItem(GD["flow_item_name"].Text, GD["from_country"].Text, GD["to_country"].Text,
                                        GD["from_sys_op"].Text, GD["to_sys_op"].Text, GD["gas_type"].Text, GD["id"].Text,
                                        GD["source_id"].Text, GD["point_type"].Text, GD["source"].Text, GD["nominations"].Text, GD["flow_item_type"].Text);
    SelectedFlows = MyFlows;

Hello Peter,

Everything looks in order and I could not find anything wrong in your code declaration. I used your code and prepared a small example and attached it to this forum thread. Could you check it and let me know how it deffers from your real setup?

All the best,
