I have a Telerik RadGrid within a .ascx (user control) that requires a *_NeedDataSource method to populate the grid's DataSource.

The same user control is doing some user authentication, simply checking HttpContext.Current.User.Identity.IsAuthenticated and doing a Response.Redirect(url, false) if it is false.

I'm seeing exceptions being raised on our live system due to the *_NeedDataSource method being called when the user is not logged in, this seems to be possible because I pass false as the value of the endResponse parameter to Response.Redirect. The original author coded it this way as I assume he was going on the guidance of the community:

1. http://stackoverflow.com/questions/947197/using-endresponse-in-a-response-redirect
2. https://blogs.msdn.microsoft.com/tmarq/2009/06/25/correct-use-of-system-web-httpresponse-redirect/

I've been trying to work out a way that I can reliably prevent execution of *_NeedDataSource without reverting to an endResponse value of true.

I can think of some ways which involve flag setting and checking but that seems inelegant and subsequent developers could forget to implement the same pattern. I've also tried implementing a base control type to derive from which overrides OnPreRender (or whatever), similar to the response from Spongeboy to this question: ASP.NET Redirect and End Page but I cannot work out the method to override that will prevent execution of *_NeedDataSource.

Can anyone recommend an approach that would work in this situation and wouldn't require too much cognitive overhead?

Hello,

Now I am looking into this demo 

http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

When I click "Add new record" button,  I can see that the delete button in the inserted row  is available.

But I cannot see the delete button with my own code.

Could you please give me some advice?

Thanks.

I have a radGrid on a page which periodically refreshes the data from the server.

The grid has filter and sorting enabled.

Is it possible to keep the sort order/filter option when the page refreshes itself? As currently it all reset on auto-refresh.

telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="grdAdminList" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
if (e.Argument == "Rebind")
{
grdAdminList.Rebind();
}

refreshGrid()
{
GetRadWindow().BrowserWindow.refreshGrid();
}

Main page function:
function refreshGrid()
{
$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");
}

Hi, I am currently using RadGrid version 5.1.1.0 in my project. Though I have set certain settings i.e.

AllowColumnResize="true"

ResizeGridOnColumnResize="true"

ClipCellContentOnResize="true"

EnableRealTimeResize="true

to True. The grid doesn't allow me to resize the columns in IE 11, however, the same renders properly in Google Chrome.

Can you guys let me know if this is a known issue with RadGrid control.
