custom filter for each column

[Khanh]

Hi all,

I am confuse when reading ms-help://telerik.aspnetajax.radcontrols.2010.Q1/telerik.aspnetajax.radgrid.2010.Q1/custom-option-for-filtering.html help file.

I have 3 columns (name=text,startdate=datetime,enddate=datetime).  The name column is set to VaryByDataType. On the startdate, I want the filter item nofilter, equalto and greaterthanorequalto.  For the enddate, I would like nofilter, equalto and lessthanorequalto.

I can't seem to get it right without affecting the other columns.

Protected Sub RadGrid1_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.Init
        Dim menu As GridFilterMenu = RadGrid1.FilterMenu
        Dim i As Integer = Menu.Items.Count - 1
        While i >= 0
            If menu.Items(i).Text = "NoFilter" Or menu.Items(i).Text = "Contains" Or menu.Items(i).Text = "GreaterThanOrEqualTo" Then
                'menu.Items.RemoveAt(i)
            ElseIf menu.Items(i).Text = "Custom" Then
                menu.Items(i).Text = "LessThanOrEqualTo"
            Else
                menu.Items.RemoveAt(i)
            End If
            System.Math.Max(System.Threading.Interlocked.Decrement(i), i + 1)
        End While

    End Sub

Thanks,
Khanh

Hello Khanh,

I have created a small sample project demonstrating the desired functionality. Please give it a try and let me know how it goes.

Additionally I would suggest that you review the following help article:

Reducing the filter menu options

I hope this helps

Thanks, Martin.  That was exactly what I needed.  Also, thanks for taking the time to create a sample project.
