Questions on UI for ASP.NET AJAX Forum

Hello,

We are essentially trying to load an ascx control per tab based on this demo: http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/loadondemand/defaultcs.aspx

The user controls load fine but on our user controls we have some CSS which creates rounded corners via JQuery and on initial page load the first tab shown and user control loaded look fine. However, when we click on the second tab to show the next user control the rounded corners are gone. This can only mean that on subsequent ajax loads it is not calling the javascript for the rounded corners properly. Why is this happening?

Further background: The CSS and Script Files that are used for the rounded corders are referenced in the master page that is referenced by the aspx page which holds the TabStrip. We have tried putting the links to these javascript files in the ascx controls directly but this has no effect.

Thanks in advance for the help.

No Xfer when AutoPostBackOnTransfer = True

RadListBox1 copies to RadListBox2 when AutoPostBackOnTransfer == false, but not if it is true - RadListBox2 remains blank. The code-behind RadListBox1_Transferring() handler fires, but there are no items in the event args. I need to intercept the value of the RadListBox1 item (a db table name) in order to populate RadListBox2 with the db table column names.

Interestingly, when I programatically populate RadListBox2 and hit RadListBox1's << xfer back button, the item text is passed to the RadListBox1_Transferring() handler.

Perhaps I am going about this a33-backwards, but I still don't get why copying (transfer) is not occuring when AutoPostBackOnTransfer is True.

Conditions:
RadAjaxManager1 EnableAjax = True
RadListBox1.AutoPostBackOnTransferring = True
RadListBox2.AutoPostBackOnTransferring = False

Invoke ItemCommand from a custom toolbar button

(Please ignore this post, since I have created a support ticket in the mean time. I will update this post, when I get a solution).

I have added a custom button to the FileExplorer toolbar (according to this help page). How can I invoke the server-side ItemCommand of the FileExplorer control when this button is clicked?

What I'd like to achieve in the end, is to load the currently selected file into a RadEditor control on the same page.

Thanks.

Performance Problems in Live Service

We are finding that the following Url is loading on every page in our live service and it is almost 1MB each time. I believe this is possibly the RadScriptManager,

Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=radScriptManager_HiddenField&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d3.5.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-GB%3a3bbfe379-348b-450d-86a7-bb22e53c1978%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2008.3.1314.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-GB%3aef502ffb-86f7-4d96-ad3a-fbb934d602ab%3a16e4e7cd%3a86526ba7%3aed16cbdc%3a11a04f7e%3a19620875%3ae330518b%3a1e771326%3ac8618e41%3ae4f8f289%3aaa288e2d%3a4cacbc31%3af7645509%3ae524c98b%3a3f6e8f3f%3a874f8ea2%3a39040b5c%3a33108d14

I include the following in our Master Page,

    
            <telerik:RadScriptManager ID="radScriptManager" runat="server"  AsyncPostBackTimeout="3600"></telerik:RadScriptManager>

Can anyone confirm this is the case and does anyone have a solution on how to prevent this problem?

I would have expected this to cache but the GUIDs must be changing in the query string causing it to download afresh each time.

We are considering adding GZIP to our ISA server but this causes issues with other services we provide so this a far from ideal.

Please help,
Kind regards

TimeSlotCreated-Event set CssClass

Hello,

for example:

If i use the following code (example from http://www.telerik.com/help/aspnet-ajax/server-side-timeslotcreated.html)

protected void RadScheduler1_TimeSlotCreated(object sender, Telerik.Web.UI.TimeSlotCreatedEventArgs e)
   {
       if (e.TimeSlot.Appointments.Count > 0)
       {
           e.TimeSlot.CssClass = "Disabled";
       } else{
           e.TimeSlot.CssClass = "Enabled";
       }
   }

The first request set this timeslot "Disabled" and the second request set this timeslot to "Enabled", the result is:
<td class=" Disabled Enabled"> </td>
(it adds the new cssClass)

If i disable viewsate, it is ok, only one cssClass there. But I need the viewstate, so what can i do?

my Version of Telerik: 2009.2.707.35

Best wishes,

Kevin

Skin Issue

Hi,

I have added a new skin file under App_Themes/Skin folder, Now I have couple of skin files one of Custom Controls and Another one for Telerik.(we can have only one register entry per skin file). Its not taking the theme like Forest or Black, I can see only default theme. Good Part is that under web.config file it is working. Since I am using ASP.NET 2X, theme should work.
I have already looked at different solution, nothing is working for me.

I appreciate your response.

Thanks,
Mihir

RadAjaxManager causing "Object doesn't support this property or method" error

I have a RadAjaxManager within my MasterPage directly below the form tag:

<telerik:RadAjaxManager ID="RadAjaxManager" runat="server"></telerik:RadAjaxManager>

I have a usercontrol where I have a RadAjaxLoadingPanel along with a RadGrid:

<

telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="75px"

Width="75px" Transparency="100">

<label runat="server">Loading...</label>

<br />

</

telerik:RadAjaxLoadingPanel>

<

telerik:RadGrid ID="grdTicket" Skin="Office2007" Width="100%" AllowSorting="True"

AllowPaging="True" PageSize="50" runat="server" AllowMultiRowSelection="true" OnItemDataBound="grdTicket_ItemDataBound"

OnNeedDataSource="grdTicket_NeedDataSource" OnColumnCreated="grdTicket_ColumnCreated" OnItemCreated="grdTicket_ItemCreated">

<telerik:GridClientSelectColumn Reorderable="False" UniqueName="ClientSelectColumn">

</telerik:GridClientSelectColumn>

<telerik:GridTemplateColumn HeaderText="WTB" DataField="wtbdt" UniqueName="WTBIndicator" Groupable="false" SortExpression="wtbdt">

<asp:Image ID="WTBIndicator" runat="server">

</asp:Image>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="wtbindicator" SortExpression="wtbindicator" Visible="false"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</ClientSettings>

</

telerik:RadGrid>

In the usercontrol Page_Load, I'm getting the RadAjaxManager from the MasterPage and then setting the AjaxSettings:

RadAjaxManager

ram = (RadAjaxManager)this.Page.Master.FindControl("RadAjaxManager");

ram.AjaxSettings.AddAjaxSetting(grdTicket, grdTicket);

ram.DefaultLoadingPanelID =

"RadAjaxLoadingPanel1";

When the usercontrol is loaded into the page and when I retrieve records for my grid, everything is fine. The problem occurs when I click on a grid header to do a sort. I get "Microsoft JScript runtime error: Object doesn't support this property or method" in the italicized code below.

Sys.UI.Control =

function Sys$UI$Control(element) {

/// <summary locid="M:J#Sys.UI.Control.#ctor" />

/// <param name="element" domElement="true"></param>

var e = Function._validateParams(arguments, [

{name:

"element", domElement: true}

]);

if (e) throw e;

if (typeof(element.control) != 'undefined') throw Error.invalidOperation(Sys.Res.controlAlreadyDefined);

Sys.UI.Control.initializeBase(

this);
