Filter menu disappear with radajaxmanager

[Alfred]

I have a radgrid and a radajaxmanager (2008 Q3) in a page.

It is a simple page, basically, it has the radgrid's NeedDataSource and an itemdatabound to generate the row numbering. 

When the page is first load, the filtering function is fine.

Then, if I perform a second filtering, the filter context memu does not appear, with script error:

'null' is not or not an object

If I removed the radajaxmanager, second filtering is ok.

The code:

 

Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs)
        Dim myTable As New DataTable
        myTable = dbSearchPart_Cost
        If myTable Is Nothing Then
            msgMessage.Text = "System error.  Cannot connect to database! "
            GoTo error_exit
        End If
        RadGrid1.DataSource = myTable

        GoTo exit_sub
error_exit:
        msgMessage.CssClass = "ErrorText"
exit_sub:
        myTable = Nothing
    End Sub

    Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound
        If (TypeOf e.Item Is GridDataItem) Then
            Dim lbl As Label = CType(e.Item.FindControl("numberLabel"), Label)
            lbl.Text = e.Item.ItemIndex + 1
        End If
    End Sub

I have amended the post with code.

Hello Alfred,

You code seems fine and works OK when I tested it in a sample page. Can you tell us how can we reproduce the issues you are having?

Also, I have noticed you are setting multiple comma-separated values for some column's DataField property. Note that this is not required, as with Eval() you can reference all data fields from the underlying data item. DataField needs to contain only one property name so that advanced RadGrid functionality is configured properly.

I am having a similar issue as well.  I am running Q2 2009.

In my code I have two radDatePicker controls and an ASP Button to apply parameters (Start and End Date) to my ObjectDatasource.  The ObjectDataSource is calling a stored procedure from a Dataset Table Adapter.  All the data is coming back as expected, but if i set my parameters to a date range that doesn't return rows, the RadGrid shows a footer and the Filters on the columns produce an "Object expected" error when I try to display the context menus.  I have added the below code to handle this behavior and it works as long as the data returned is 1 page or less of data.

    Private Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.PreRender
        If RadGrid1.MasterTableView.Items.Count < RadGrid1.PageSize Then
            If Page.IsPostBack Then RadGrid1.Rebind()
        End If
    End Sub

If i return more than 1 page of data, the error "Object expected" is reproduced and the filter buttons on the columns no longer display the context menus.

I am at a loss.  Any ideas?

Listed below is the full code for the page in question...

When I have more than 1 page of data, I have now also noticed that when i drag a column to the header, I no longer get the arrows indicating where to drop.

I did a little more debugging and i found that the generated code is different for the filtermenu

code that works:

Any idea why this would be changing?  Does this relate to the issue?

[Terry Webster]

I have found this issue with my code.  In the master page i had a scriptmanager that was referencing js files that were not found.  I removed the bad links. I also changed the button onclick event to rebind the radgrid and removed the prerender code that was listed below for the radgrid.

Everything now works as it should.

[Alfred]

Dear Veli

Thanks.  Actually I tested the scenario.  I found that:
1. If the radgrid is loaded in an ASPX page, it is OK.
2. If the radgrid is loaded in an ASCX, it is not OK.

BTW, I know one data field name is enough but I am just too lazy to remove them.

Pls. download my testing code to see if anything I coded it wrong.

Hello Alfred,

As we have escalated your problem discussion to a support ticket, I suggest we continue with the support communication instead of this forum post.

For our readers, I just want to note that if there is an issue with a RadGrid inside another RadGrid's NestedViewTemplate firing the parent server-side events on click or row drop, this is probably due to the event bubbling from the inner to the outer grid. To fix this phenomenon, we need to cancel  the event bubbling mechanism in the DOM by attaching a client-side onclick or onkeydown (for drag and drop) handler to the RadGrid wrapper <div> element:

<telerik:RadGrid ID="RadGrid1" runat="server"
onclick="if(!event){event = window.event}; event.cancelBubble = true; if(event.stopPropagation){event.stopPropagation()}">
</telerik:RadGrid>
