How can we get accurate numbers out for aggregates applied to a grid with virtual paging enabled?

I've recently switched over a grid to virtual paging. Before, the code would just select everything and let the control work out what to display and how to deal with groups and aggregates. However, many of my customers were running into issues (understandably) with large tables - those containing a few hundred thousand or more. The grid was taking forever to display / group / page / etc.

Now, the grid is very high performance, thanks to the new MSSQL 2012 OFFSET... FETCH NEXT statement - it's about time they implemented that! While it's high performance, i've now lost the ability to do grouping and aggregates correctly. It will only summarize what is on the current page. Certainly that makes sense - there's no way for the telerik grid to read data it hasn't been handed.

So - how do i correct this? I don't need a full-blown example, but rather just a quick push in the right direction. Is there a function i can override to deal with the groups / aggregates manually? Is that the right choice? Any help here would be appreciated!

Thanks!

New RadRibbonBar and Width="100%"

Hello,

System: ASP.NET AJAX 2012.2.607.40

In previous version of RadRibbonBar, it was possible to let it to follow the width of the parent component, even with the window itself, by setting its Width="100%".
This doesn't work anymore with the new version of RadRibbonBar.
Any workarounds exist?

Best regards,
Alain

GridTableView row count

In my grid table view, I want to have my last column to take the span of all the rows in the tableview.

In order to do this, I need to be able to loop through all the rows of the gridtableview but when I try the following in my DetailTableDataBind :

e.DetailTableView.Items.Count

it always returns 0.

What can I do in order to achieve this?

Thanks

Preview Mode + Floating Toolbar issue

Hello all,

I am using a RadEditor in where I need to enable Edit Mode or Preview Mode based on permissions (Only specific users can edit the content).

So, it is working OK but because of space, I need to use the "Floating" toolbar option.

The issue appears when I set Preview Mode + Floating Toolbar...and it is that the toolbar allows me to edit the content...If I use "Default" Toolbar mode...it appears as "grey out" and I cannot use it...achieving what I need...but if I go back to "Floating" mode, the restriction goes off.

Please let me know if you have any ideas about what could be happening.

This is what I am calling in the "OnLoad" method...

private void SetEditorMode()

{

this.HelpContentRadEditor.ToolbarMode = EditorToolbarMode.Floating;

this.HelpContentRadEditor.EditModes = EditModes.Preview;

}

I also tried with JavaScript with no luck...

function OnClientLoad(editor, args) {

setTimeout(function () {

editor.set_mode(4);

}, 150);

}

Thanks all for your help!!!

RadGrid NestedViewTemplate - bind from session variable throws exception

Hi,

I followed Grid/NestedViewTemplate Relations demo to bind one grid that has a nested view, everything is working properly.
But when using ObjectDataSource as a DateSource for NestedView and that object datasource uses a server side method to pull data from a Session variable, I'm getting
System.NullReferenceException: Object reference not set to an instance of an object

Here is ObjectDataSource declarative markup

<asp:ObjectDataSource runat="server" ID="MemberSubmissionData" TypeName="FacultyAnnualReview" SelectMethod="BindNestedView">
     <SelectParameters>
        <asp:Parameter Name="SubmissionId" Type="Int32" />
    </SelectParameters>
</asp:ObjectDataSource>

and here is server side method

        public FacultyMemberSubmission BindNestedView(int submissionId)
        {
            return  (
                        from data
                        in GetFacultyMemberSubmissions()
                        where data.SubmissionId == submissionId
                        select data
                    ).SingleOrDefault();            
        }

GetFacultyMemberSubmissions() method pulls data from a Session variable. When updating it to not use session, everything is working. So is that something that is related to ObjectDataSource or NestedView binding doesn't accept session variables. Any suggestions?

Multi-word 'between' filter strings?

When doing a filter in a string field in a RadGrid, is there any way to filter on a multi-word string?

That is, suppose you want to find all string fields in a column that begin with anything between "this is" and "this will"?
