Sys.WebForms.PageRequestManager null or not an object

I have a radlistbox on a page and when the page loads I get this javascript error:

Sys.WebForms.PageRequestManager is null or not an object

Here is the page code:

<

telerik:RadScriptManager ID="RadScriptManager1" runat="server" />

<

telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1">

Player Name:

 <telerik:RadTextBox ID="radtxtAddPlayer" MaxLength="110" runat="server" /><asp:Button ID="btnAddPlayer" OnClick="btnAddPlayer_Click" Text="Add Player" runat="server" />

<

telerik:RadListBox ID="radlstPlayerPosition"

runat="server" height="300px" width="150px"

DataTextField="PlayerName" DataValueField="nPlayerID" AllowDelete="true"

AllowReorder="true" AllowTransfer="false" AutoPostBack="True">

</telerik:RadListBox>

</

telerik:RadAjaxPanel>

Any ideas why I would get this error? adding a player works even with the error there???

RadGrid and RowClick

Hello,

I have a RadGrid:

<tel:RadGrid ID="MG" runat="server">
   <MasterTableView DataKeyNames="Key" AutoGenerateColumns="false"
       Width="450px">
       <Columns>
           <tel:GridTemplateColumn HeaderText="Subject">
               <ItemTemplate>
                   <a href='<%# Url.Action("Select", "Messages", new { message = DataBinder.Eval(Container.DataItem, "Key") }) %>'><%# Eval("Subject") %></a>
               </ItemTemplate>
           </tel:GridTemplateColumn>
           <tel:GridBoundColumn HeaderText="Subject" DataField="Subject" />
           <tel:GridBoundColumn HeaderText="Sent" DataField="CreatedDate" DataFormatString="{0:MM/dd/yyyy}" />
           <tel:GridBoundColumn HeaderText="Last Reply" DataField="LastReply" />
           <tel:GridBoundColumn HeaderText="Reply Date" DataField="ReplyDate" />
       </Columns>
   </MasterTableView>
   <ClientSettings EnableRowHoverStyle="true">
       <ClientEvents OnRowClick="MG_RowClick" />
       <Selecting AllowRowSelect="true" />
   </ClientSettings>
</tel:RadGrid>

The MG_RowClick event never fires in my MVC view. The script is in the same place as my MVC view...   SelectedIndexChanged doesn't fire either.

How do I get that to work?

Thanks.

Recursively expand groups

Hello,

I have a grid setup with multiple groups. The groups are year, month and day. By default, all groups should be closed except the one of todays date, that one should be expanded.

I've got the code to retrieve the GridGroupHeaderItem object for the group which matches todays date (year-month-day), and I can expand that. But I need all of the above groups (year, month) to be expanded as well. What is a good way of traversing up the group hierarchy to expand all groups above? I would like to make this function recursive so I can use it again some other time, so it ideally shouldn't be fixed to a number of parent levels.

Adding a ProgressArea

Hi Folks,

Is it me or should this be simple? I just want to add a progressarea like in the Telerik examples. When I first added it to my project I got the error about it not being registered in the config file, so I put these lines in:

    
            <httpHandlers> 
        
                    <add path="Telerik.RadUploadProgressHandler.ashx" validate="false" verb="*" type="Telerik.Web.UI.RadUploadProgressHandler"/> 
        
                  </httpHandlers> 
        
                  <httpModules> 
        
                    <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule"/> 
        
                  </httpModules>

Now it doesn't throw any error but doesn't actually do anything when I upload a document! Is there a step-by-step guide of how to add a progressarea properly?

Thanks,
IW

RadTextBox button

Hi,

I just started developing using RadControls for ASP.NET AJAX since last week and I'm stuck with RadTextBox column inside a RadGrid....

I have a RadGrid with parts that look like this:

//------------------------------------------------------------------------

<telerik:RadGrid ID="RadGrid1" .......>

....

<MasterTableView....>

<telerik:GridTemplateColumn UniqueName="D1">

<telerik:RadTextBox ID="tb_D1" runat="server" ShowButton="true"...>

</telerik:RadTextBox>

</EditItemTemplate>

....

</telerik:GridTemplateColumn>
</Columns>

</MasterTableView>

</telerik:RadGrid>

//------------------------------------------------------------------------

I need to either do processing at RadTextBoxButton_OnClick() at server side

OR

pass an integer to a RadWindow form to let user enter a String input and then pass the result back to this grid page for processing.

<buttontemplate> doesn't work for this RadTextBox column inside the grid... so how do I find the button ID of the RadTextBox's button??

and with <buttontemplate> not working, I can't change the appearance of this button right??

Any help will be greatly appreciated.

Thanks

Ryan

RadToolTip and ManualClose property

I am using RadToolTip in my application to show the help. I have set the property "ManualClose" to TRUE, but I want to display the text right beside the close button, so that when user clicks either text or the button, tooltip gets closed. How can I put the text "Close" beside close button and code it so that desired functionality is achieved.

RadUpload (progress bar) require full trust

I wanted to know if RadUpload (RadProgressBar) still required Full Trust in the latest 2009 Q3 release. I realize my question is answered in the release notes:

http://www.telerik.com/products/aspnet-ajax/whats-new/release-history/q3-2009-version-2009-3-1103.aspx

Fixed: RadUploadHttpModule should not throw an exception when an attempt is made to use it in medium trust

I would like to understand more details. Is there functionality difference between Full and Medium Trust?

Thanks!

[Solved] RadWindow not displaying in dual monitors

Hi there!

I have a link that displays a RadWindow, but when I tried to extend it to display in my extension monitor it doesn't show up, it somewhat extending the page horizontally in the primary monitor.

Is there a way to change its properties or a script to make it display in the extension monitor?

Hope I can find a solution for this topic.

Here's my script in my sample webproj:

markup:

        <telerik:RadWindowManager ID="WindowManager" runat="server">
            <Windows>
                <telerik:RadWindow ID="RadWindow1" NavigateUrl="Default2.aspx" runat="server" />
            </Windows>
        </telerik:RadWindowManager>
        <a href="javascript: openWindow();">RadWindow</a>

        <script type="text/javascript">

            function openWindow() {
                radopen('<%= ResolveUrl("~/Default2.aspx") %>', "RadWindow1");

            }
         </script>

Regards,

Reynald.

How to bind for insert via VB
