I have a radgrid that inherits it hierarchy from a System.Data.DataSet. When I make a change I update the database from which the DataSet gets its data and rebuild the grid as this answer suggests. The first time the update always runs as expected and updates in the grid. After that after varying amount of changes( I can't seem to figure out exactly which one causes this) I get the following error:

JavaScript runtime error: Unable to get property 'get_element' of undefined or null reference

I hope you are able to help

Hi

How to Use EditTemplate in Telerik Grid using list object for CRUD OPERATION No needSql datasource i need server side code how will do this

Since we upgraded to Telerik version 2015.1.225.40, the All Day appointments in WeekView mode are truncated as shown the attachment.

If there are only a few appointments, I managed to programmatically make their width 100%. But as seen in the image, this has no effect when there are many appointments in one day. It's like there's an issue in the computation of the appointment width or something. I noticed in this example all the appointments have style of "width: 2.98578px; margin-left: 63px;" for what that's worth.

Any idea?

Hi

I have a radgrid inside RadPageView. I have a submit button and uses jquery click event to retrieve data using wcf. I am getting data and able to bind it. After binding, some scroll event gets triggered and causes a postback. As I don't have any logic to retrieve data on the page postback, the grid is empty again.

How to stop the events from triggering...

Also, paging is enabled, but the grid displays all records at one shot which I believe causes the scrolling, but which one ?.

Here is my code snippet.

Default.aspx

$(document).ready(function () {
//alert('To Date Click');
$('#ctl00_ContentPlaceHolder1_btnSubmit').click(function () {

 var uri = "../Default.svc.cs/GetData";

var datival = "userId="+12345;

$.ajax({
url:uri+dataval,
type:'GET',
async:false,
dataType:"json",
contentType: "application/json;charset=utf-8",

error: function (XMLHttpRequest, textStatus, errorThrown) {
//$('#loading').hide();
alert(errorThrown);
alert(XMLHttpRequest.statusText);
alert(textStatus);
                        
                        return true;
},

success:function(data){
alert('Data retrieved:' + data);
var gridDealers = $find("<%=radGrid1.ClientID %>").get_masterTableView();
gridDealers.set_dataSource([]);
gridDealers.dataBind();
var gridData = data["DataGridList"];
gridDealers.set_dataSource(gridData);
gridDealers.dataBind();
                        
                        
                        }

}):

});

I am using UI for ASP.NET AJAX v.2015.1.401.45, when I use the upload function for documents (also for images, media or flash) I can create a new folder, delete files inside those folders, delete the folder and  browse from folder to folder. But when I try to upload a new document, I see for a second the process circle then nothing get uploaded to the server. Since I can work with other functions, I don't think is a permission problem. My radeditor code is this:

<telerik:RadEditor ID="reTemplateHTML" runat="server" Content='<%# Bind("EmailBody")%' Width="100%" Height="800px" ContentFilters="DefaultFilters,MakeUrlsAbsolute" Editable="true" EditModes="All" AllowScripts="true" >
<ImageManager 
ViewPaths="~/uploads/images/" 
UploadPaths="~/uploads/images/"  
DeletePaths="~/uploads/images/"  
EnableAsyncUpload="true" 
MaxUploadFileSize="3145728"  />
<TemplateManager 
ViewPaths="~/templates/" 

MaxUploadFileSize="3145728"  />
<FlashManager 
ViewPaths="~/uploads/flash/" 
UploadPaths="~/uploads/flash/" 
DeletePaths="~/uploads/flash/" 
EnableAsyncUpload="true" 
MaxUploadFileSize="3145728"  />
<DocumentManager 
ViewPaths="~/uploads/documents/" 
UploadPaths="~/uploads/documents/" 
DeletePaths="~/uploads/documents/" 
EnableAsyncUpload="true"
MaxUploadFileSize="3145728" />
<MediaManager 
ViewPaths="~/uploads/media/" 
UploadPaths="~/uploads/media/" 
DeletePaths="~/uploads/media/"
EnableAsyncUpload="true"
MaxUploadFileSize="3145728"  />
</telerik:RadEditor>

Any Ideas. I have another app that use this feature and is working fine. But that is in the previous version of ASP.NET AJAX. Any Idea?

Thanks
