Filter button outside of grid

[AereoN]

I have a grid with custom radtextbox for in the filter template.
Instead of the filter button that usually is found in the grid, I want to place my filter button outside of the grid.
Can someone show me how do I achieve this?

Thanks.

Hello AereoN, 

Check out the following code and see if helps achieve your scenario:
aspx:

<asp:Button ID="Button1" runat="server" Text="Filter" OnClick="Button1_Click" />
.....

<telerik:GridBoundColumn DataField="ProductName" HeaderText="Product Name" UniqueName="ProductName">
       <FilterTemplate>
            <telerik:RadTextBox ID="RadTextBox1" runat="server" ></telerik:RadTextBox>
       </FilterTemplate>
</telerik:GridBoundColumn>
...

c#:

protected void Button1_Click(object sender, EventArgs e)
    {
        GridFilteringItem filter = (GridFilteringItem)RadGrid1.MasterTableView.GetItems(GridItemType.FilteringItem)[0];
        RadTextBox txtbx = (RadTextBox)filter["ProductName"].FindControl("RadTextBox1");
        RadGrid1.MasterTableView.FilterExpression = "([ProductName] LIKE \'%"+txtbx.Text+"%\')";
        GridColumn column = RadGrid1.MasterTableView.GetColumnSafe("ProductName");
        column.CurrentFilterFunction = GridKnownFunction.Contains;
        column.CurrentFilterValue = txtbx.Text;
        RadGrid1.MasterTableView.Rebind();
    }

Hope this helps..
Princy.

Thanks for the reply, Princy.

Actually I tried several methods already and I'm always stuck  at the Grid rebinding issue where this error will always occur.
ParseException was unhandled by user code: Expression expected.

This error even occur using your example.
Any help please?
