Version:  5.3.11.1116
Grid properties in aspx:

<telerik:RadGrid runat="server" ID="Grid" PageSize="20" Width="100%" EnableViewState="false" CssClass="basicList">
<MasterTableView  AutoGenerateColumns="false" AllowPaging="true" AllowCustomPaging="true" AllowSorting="true" DataKeyNames="ID">

We are using custom sorting and paging, and filtering.  We retrieve data via a stored procedure that returns the data sorted (but then the grid also sorts... see #2). 

We are experiencing two problems:
1) Event sequence is causing 2-3 calls to the database on sorting or filtering -- first from NeedDataSource, and then from the sort or filter.  This raises scalability concerns.  How can we resolve?  When I use the following in the NeedDataSourc event as suggested in another post, the sort doesn't happen:
      if (e.RebindReason != GridRebindReason.PostbackViewStateNotPersisted)
            {
                LoadData(false);
            }
How can we retrieve data once and only once in all scenarios (initial load, sorting, fitlering, page size change, page index change, etc.)?

2)  In addition to reloading the data on sort, we are seeing an incorrect sort in at least one scenario.  Our default sort is descending on a datetimeoffset datatype column.  On page load, sort appears to be correct.  When one clicks on that column header, it correctly sorts ascending on those dates.  But when the column is clicked again to sort descending, it does not sort correctly --
e.g., it sorts a range from 12/08/2011 5:05 PM down to  12/05/2011 3:39 PM
then a range from  12/29/2011 3:33 PM down to  11/11/2011 4:58 PM,
and then a range from 01/04/2012 2:36 PM down to 01/04/2012 2:31 PM
The database is returning the data correctly sorted, so the grid is clearly resorting. 
Clicking again then correclty sorts by our default descending sort.  In this third state, the column now shows no sorting icon, so it's presumably correct because the grid is not resorting incorrectly at this point. 
But I haven't been able to find where or why.
How can we eliminate this incorrect sort?  Why & where/when (what event) is it happening?


Our LoadData() method accepts a boolean rebind parameter and calls Grid.Rebind() if true.

We have coded to the following events:

Grid.PageIndexChanged:  Calls LoadData(true) 
Grid.PageSizeChanged:  Calls LoadData(true) 
Grid.SortCommand:  Calls LoadData(true) 
Grid.ItemCommand:  Calls LoadData(false) and Grid.Rebind() 
Grid.ItemDataBound
Grid.NeedDataSource:  Calls LoadData(false)
 
Page_Load: If not a postback, calls LoadData(false)

I can send this page code privately if needed.


Thank you.

I created a toolbar with a button that launches a radwindow. However, when I close the radwindow, the toolbar does not respond. The mouseover and mouseclick events don't react. This problem is specific to the toolbar, because if I use a plain radbutton, it works fine.

This is either my fault (I don't have radtoolbar/radwindow configured correctly) or it is a bug. Any help would be greatly appreciated.

Is there a property somewhere which will expand\collapse nodes, and\or set the default node state to expanded?

(without having to do a ItemDataBound)

Hi

I'm trying to use the visual style builder but I keep getting some javascript errors.


Has anyone experienced the same issue? Is there a fix?

Thanks
Martin.

In My application have so many Grids. I want upgrade it all by using Telerik Grid.
My idea  to implement radgrid as a usercontrol and column names should be defined in each page of config files.
can any one provide me the way of approach and steps to create it. Thanks in advance.

We use RadControls for ASP.NET AJAX version 2011.2.712. And we think the point (.) on the numeric keyboard isn't functioning correctly in MS IE 9 for the RadNumericTextBox.

We use the following markup for the control.

 

<telerik:RadNumericTextBox id="tbVanKm" runat="server" Width="150px" 
    MaxLength="10"  NumberFormat-GroupSeparator=""  
    NumberFormat-DecimalSeparator="." NumberFormat-DecimalDigits="3" 
    Culture="Dutch (Netherlands)">

    <ClientEvents OnError="onError" > </ClientEvents>

</telerik:RadNumericTextBox>

Can you provide me with a link for a good online visual style builder tutorial?

Thanks,


Steve Holdorf

Hi,
   I have a grid that I am creating programmactically. Everything in the grid works fine. In the Column created Event I am setting the
Column.AutoPostback property to true. When I try to fiter on any of the columns I am getting this error

Microsoft JScript runtime error: 'value' is null or not an object

This is happening on all the column filters. Can someone tell me what is causing this since this is making the filtering useless for the grid? Please let me know since this is kind of a vague error from ajax and im having a hard time trying to find the cause and solution around it, your helps appreciated!!

I want to set the "NumberFormat-DecimalDigits" of a RadNumericTextBox at run time when it is created. But I am unable to find in which event i can do so and how.

Please help me out !
