Hello,
I have a hierarchy grid with one nested level.
I'm having some issues with HierarchyLoadMode setting set to Client on my grid.
I load my grid on during Page_Load event, and it is loaded without any issues.
After that, the event to load the DetailTable is called:
I get an exception - +  ex {"Invalid attempt to call FieldCount when reader is closed."} 

I am not sure what I'm doing wrong, because if I don't set hierarchyModeLoad to Client, the exact same code runs without any issues, and I can expand/collapse the rows.

I would appreciate any help.

Whenever I point to appointment by mouse, the error for get_allowdelete raise. How can I fix it?

Hello,

Recently I have migrated our development evironment over to IIS 7 on Windows 2008 from IIS 6 on Windows 2003.  Everything seemed to be working fine at first.  However, I noticed when I tested the website on a workstation when logged on as a user without internet access, the site continues to get a 'Telerik' is undefined error message.  Using Fiddler, I was able to see the problem is there are calls to the following websites, aspnet-skins.telerikstatic.com or aspnet-scripts.telerikstatic.com.  Becuase this user does not have internet access, these calls are failing with HTTP 502 errors and causing issues with all the Telerik controls.

Is there something that needs to be done to avoid these external calls from being made so users without internet access do not have this issue and the site/controls are displayed properly?

Thanks,
Ron

can anyone show me the example?

Folks,

Using VS2010 with RadControls for Ajax Q1 2012.

I need some help with following issues:

1) For Example, while using Command Item Template, I can hide the the EditSelected Command Button based on RadGrid1.EditIndexes.Count of Master Table, How can I accomplish the same result  with Child Table (i.e. hide EditSelected Command Button based on RadGrid1.EditIndexes.Count of Child Table)?  Basically I do not want to show Child Table  EditSelected Command if there are no Child rows.

To get Child Table Edit Indexes count I tried to below line of code but is not working.

Visible='<%# RadGrid1.MasterTableView.DetailTables[0].EditIndexes.Count > 0 %>'>

Below is my Master/Detail Command Items Template.

2)  Below link from Telerik Documentation shows Making a Grid Row Selected at All Times (similar to WinForms grids). How can I accomplish the same result with Child Table (I have multiple Child Tables)?

http://www.telerik.com/help/aspnet-ajax/grid-selected-row-at-all-times.html

3) Below Thread solution by Princy demonstrated Select Inserted/Updated row after performing command in Master Table. How can I accomplish the same result with Child Table (I have multiple Child Tables)?

Thank you very much for any help.

  I'm using Radwindow as a popup.I'm invoking this from a parent page which is part of another page.
Radwindow is opened with the ajax script from the parent page
Now I'm loading another aspx page with in this Radwindow.
If I press F5(refresh) parent window and the radwindows are closing but the aspx page is displayed in the default page.
Now I need to close the aspx page also along with the radwindow.

Scenario:

Defaultpage.aspx in which Example1.aspx is loaded
From Example1.aspx --> Radwindow is opened as popup in which Example2.aspx is loaded

Please help me on this

Hi:
I have a working portal page with web-part zone containers.  In the Master page I added a RadAjaxPanel around the main content area and now the automatic management stopped working (design, ie deleting and re-arranging).  Any ideas?

Hi Team,
We are migrating to Telerik's dll with version "2010.2.929.20". Currently we are facing an issue with RADAjaxManager.
Initially we declared RADAjaxManager in .aspx page and AjaxSettings where added dynamically in Page_PreRender event.
Now, after rewplacing the dll I've moved the dynamically added AjaxSettings from .cs -to-> .aspx.
telerik:RadScriptManager tag is on my Master page.

we are using Client Side API i.e.,

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
  <script type="text/javascript" language="javascript">
    function RequestStart(sender, eventArgs) {
      alert('inside RequestStart');
    }
    function RequestEnd(sender, eventArgs) {
      alert('inside RequestEnd');
    }
  </script>
</telerik:RadCodeBlock>
<telerik:RadFormDecorator ID="RadFormDecorator1" runat="Server" />
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
<ClientEvents OnResponseEnd="ResponseEnd" OnRequestStart="RequestStart" ></ClientEvents>
 <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="Button1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadAjaxPanel1" LoadingPanelID="LoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>



Problem is some how on button click none of the clientevents are getting called and neither do i see any difference in terms of page postback's. I mean Page does not seem to be ajaxified. Please help.

Thanks

I have a GridView that is inside a RadAjaxPanel, a RadPageView and RadMultiPage. It should be a pretty simple read-only display of records from a single table (10 fields, nothing complex), but unfortunately I seem to be getting the same problem as many (hundreds?) others in this forum, none of whom have appeared to get an answer so far.

With Internet Explorer, everything is initially displayed correctly, but if I click somewhere on the grid, the filter row, detail section and the pager will disappear leaving the grouping header still there. If I resize the window by grabbing a window handle, everything reappears with my selection being made. During these two transactions, there is no interaction with the server. I can group and sort and everything else works fine; I just can't click in the "data rows" section. Lastly, if I click really fast (the "mouse up" follows the "mouse down" very closely), none of the bad behavior happens - how about that?  The dump from the client side is below (there is some mouse movement included in there as well as what cleared the screen - I am assuming that these calls would mean something to a Telerik person). 

When using either Opera, Chrome, Safari or Firefox, the same code will not display correctly initially but if I resize the grid by dragging a window handle, everything becomes visible and looks fine. I can click wherever I want and nothing disappears. I can sort, filter and group. Everything works fine except the initial display.

Because of some of the recommendations, I tried implementing "NeedDataSource" handler, but the event code has never been fired through my last 30 or so hours of trying to fix this bug.

Has anyone else seen (and more importantly been able to fix) this issue?  I am using all the latest releases of everything, I have all the latest patches of everything applied to everything.

This is a client trace of when I clicked IE and the GridView sections disappeared (columns are Function, count, Inclusive time, exclusive time, URL, line number):
