I m using the filter option in radgrid to filter some data on basis of the option selected in dropedown menu. Now on changing the dropdown value and clicking on submit button, my filter expression test is still there and the data gets filtered. How do I remove the filter in the text box.
Please help!
Thanks in advance.

Hi Princy,

In my case there is a <MasterTableView> <DetailTables> within the RadGrid. Both Master and Detail tables have filtering enabled and it works perfectly fine. When I try to remove the filterexpression at the DetailTable level (using the 'nofilter') menu option, the filter expression still persists in the textbox. How can I remove this? What code can I write to identity if the filtering request happened from mastertable or detailtable? In the end, I just want the text from the filter textbox to disappear.

Sample code:

<telerik:RadGrid ID="SomeGridView" runat="server">
...
<ClientSettings>
    <ClientEvents OnFilterMenuShowing="FilterMenuShowing" />
</ClientSettings>
...
<Columns> ... </Columns>
...
<DetailTables>
    <telerik:GridTableView Name="Details">
        <Columns>
            <telerik:GridBoundColumn DataField="FieldName" HeaderText="Some Header" SortExpression="FieldName" UniqueName="FieldName" />
...
        </Columns>
    </telerik:GridTableView>
</DetailTables>
</telerik:RadGrid>

I think I resolved my own question.
But I find this extra effort was not needed for the MasterTableView filters, since it automatically cleared the textbox values when I selected "NoFilter".
Is this a known Telerik bug?
Is it fixed in the latest version? My version is 2015.1.225.45


        protected void RadGridView_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)
        {
            GridDataItem dataItem = e.DetailTableView.ParentItem;

            if (IsPostBack == true)
            {
                foreach (GridColumn thisColumn in e.DetailTableView.Columns)
                {
                    if (thisColumn.CurrentFilterFunction == GridKnownFunction.NoFilter)
                    {
                        thisColumn.CurrentFilterValue = string.Empty;
                    }
                }
            }
        }
