Hello All,

First Issue
 I am trying to use RadGrid and the data source for this comes from a webapi. I have successfully added the data to the RadGrid. But, the issues is that there are over 10,000 records the api returns and takes 20-30 min to load the RadGrid. To make things easy on data binding and loading, I have tried to create dynamic RadGrid. The idea is to call the api and return only 50 records on every page change. The pagination wont show because, I am retrieving only  50 records every time. So the first page shows up with 50 records and I cannot paginate as there are no pages showing up.

2nd issue
 I need to add a search box and allow searching for a record. I could achieve this when I created radgrid using ASPX. But, dynamic creation of radgrid, I have to call the api's every time and load the grid again and then search for the data which (according to me) is inefficient. The same with export to CSV. I have to recreate the radgrid every time.


Are there any better ways to do this without dynamic radgrid, and still be able to paginate and call the api when ever the next page is clicked. I am using C#. I understand it will be hard for you all to picture what I am  trying to say, but, I really appreciate any help or suggestions or questions that guide me in the right direction.

Thank you in advance

I have the below code to attempt to ajaxify my grid and subsequent detail panel. It works but the trouble is when I click my "select" link on a row, the style doesn't change to selected row as I have not re-drawn the grid (grid not part of the updated controls list).  I do this intentionally because I don't want to reload the entire grid if no data has changed (it is simply a row selection).  The grid also has sorting enabled which does not function unless I add the grid to the updated control list. So the question is, how to I retain server sorting control but also allow simple row selection without having to pull the whole grid down again?

Thanks

Please help me with this:

I have this problem between the old version and new version (2012.3.1038.40 vs 2013.3.1015.40)

I am using customized column editor (I want a drop-down, rather a free-style type field), pelase see the code in the end.

my question is, the following code works perfectly with version 2012.3.1038.40 (I know it is an old version)
but after I referred to the new Telerik.Web.UI with version 2013.3.1015.40, I got exception as below

[NullReferenceException: Object reference not set to an instance of an object.]
Telerik.Web.UI.GridTextBoxColumnEditor.CreateControls() +264
Telerik.Web.UI.GridColumnEditorBase.EnsureControlsCreated() +56
Telerik.Web.UI.GridColumnEditorBase.InitializeInControl(Control containerControl) +77
...
...

by setting debug line in customized editor class, I found out that with the new version, AddControlsToContainer() never get called

If I switch back the old DLL version, everything is just working fine.

we are desperately looking for help!!!
Just cannot upgrade any newer version

Thanks in advance

Hi,

We're having an issue with a RadGrid when there are no records returned.   Here's the scenario - this grid has several columns in it that are either hidden or visible based on a boolean value.  When the grid has data bound to it, I am able to scroll completely to the right and view all of the columns.  But when there are no records bound to the grid, the scrollbar will not allow the user to scroll all the way to the right.  I double checked this by moving my last column up two or three in the sequence - once I did that, I was able to view the moved column, but the two columns before it are now not visible. 

Is there a way to force the scrollbar to "reset" after the columns have been setup? 

Thanks,
Jerry

Pressing enter on a combobox that allows custom text causes the selected event to fire.  My handler for the event does a get_item(), which returns a null value.  This problem seems to be a repeat of this problem that was determined to be a bug and then fixed:

I don't need a reply; I have found a workaround.  But this does appear to be a problem that should be addressed.

I am trying to use Jquery UI dialog one of my pages. Here is the code I have. But this doesn't work. I am using 2013.2.611.40 version controls.

Master page:
------------------------
<head runat="server">
    <link href="../css/ui-lightness/jquery-ui-1.10.3.custom.css" rel="stylesheet" />
</head>
<body>
    <form id="form1" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server" OutputCompression="AutoDetect">
    <Scripts>
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />

    </Scripts>
    </telerik:RadScriptManager>
    <script type="text/javascript">
        window.jQuery = window.$ = $telerik.$;
    </script>

.aspx page:
----------------------------------
 <script type="text/javascript">
     $telerik.$(document).ready(function () {
            $("#dialog").dialog('open');
        });
</script>

I am getting object doesn't support this property or method at this line ' $("#dialog").dialog('open');' Could you please let me know what could be wrong?

Hi,

I am having problems using virtualization on tablets (IOS 7, Windows RT 8.1).
In your demo I can't get past the first 100 items when scrolling by swiping!

Hi,

I have CellTemplate for each PivotGridRowField which is an User Control. For the first load everything works fine, but when I reorder, template is lost and instead cell normal text is displayed. Please download project from below link to see how it happens. Just replace ItemGroup with InventSite using "Drag to Reorder", you will see ItemGroup is not using template. But after than, if you expand any of ItemGroup it binds to template again. I am using version 2013.1.417.40
