Hi,

My application receives parameters from a query string, so these are all strings.

The problem that I have is that in my form, there is a DateTimePicker which needs to be updated with one of these values.

The client side API, set_date, expects a date, and honestly I do not know how to convert a string (or a single) to a date from client side java script. Is this possible?

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");
}
