Ajax Loading Panel not showing on the page

We have a rather peculiar issue going on with the ajax loading panel.

First, the changes we did:

We have upgraded from Telerik Q3 2010 to Q3 2011
We have updated the solution from VS 2008 to VS 2010
We have also updated the project to use the .Net Framework version 4.0 from 2.0
The project is being published to a separate machine running on IIS 7 (previously was on IIS 6 on the same separate machine)
We are using a 64 bit application pool with integrated mode (previously was 32 bit classic mode)

When we run the aspx site from within Visual Studio, it works fine and the loading panel shows up as expected.

However when we publish to the other machine, that's when it looks odd. The loading panel doesn't show at all (although the processing of the aspx page still appears to work). Checking with fiddler also shows that the loading panel doesn't work (nothing is sent/received).

We have the following code in the aspx page:




<telerik:RadAjaxManager id="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="btnValidate">
                             <UpdatedControls>
                                   <telerik:AjaxUpdatedControl ControlID="divAll" LoadingPanelID="RadAjaxLoadingPanel1"></telerik:AjaxUpdatedControl>
                               </UpdatedControls>
                </telerik:AjaxSetting>
           </AjaxSettings>
</telerik:RadAjaxManager>
 
 
<telerik:radAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" mindisplay="5000" ZIndex="10000">
     <asp:Image ID="Image2" runat="server" ImageUrl="../images/Loading3.gif" alt="loading..."  />
</telerik:radAjaxLoadingPanel>

We are not sure what else we might be missing?

Closing a radwindow which has generated a non-HTML content to response stream

I have a page and clicking of a button opens a small RadWindow. Here the user makes some selections and clicks 'Generate' button. Now the server will start to stream a PDF file. Now radWindow.VisibleOnPageLoad = false does not work because the response stream is now PDF and not normal content type text/html

Is there a way to close the RadWindow in this case or is it a bug/limitation with Telerik RadWindow?

ToolTipManager + Anchor Tag + AjaxUpdate

Is the above possible ?

Essentially, i've got a collection of html anchor tags. I've set them to runat server and added their i'd to the target controls of the RadToolTipManager.

What i want to do is have each of these anchor tags cause an ajaxupdate request of the tooltipmanager and show the tooltip.
Each of the anchor tags has an id, which relates to an id in my database. I therefore want to query the database with this ID and pull out the appropiate information associated with the anchor tag.

The anchor tag enscapsulates an image, so if there's an easier way in which i should use a different control/element let me know.

Regards,

Alan

match the text of radgrid field to dropwdownlist

What I am trying to do is match the text of my grid field to my dropdownlsit field text, but it always gives me the follwoing error even though the text is in the item is in the dropdown list in the grid. I am trying to match computer make and models that come up from and existing table to a new database. for example.

Optiplex 755
Optiplex 760
Precision 2000
latitude 2400

In my dropdown inside my radgird these are all in there but when the match tries to happen it tells me they are not, it should nto be a case issue.

<telerik:GridBoundColumn DataField="strSN" HeaderText="SN" />
                                <telerik:GridBoundColumn DataField="strComputername" HeaderText="NETWORK NAME" />
                                <telerik:GridBoundColumn DataField="strBrand" HeaderText="EXIST_MODEL" />
                                <telerik:GridTemplateColumn HeaderText="DB_Model">
                                    <ItemTemplate>
                                        <asp:DropDownList ID="ddlModel" runat="server" CausesValidation="false"></asp:DropDownList>
                                    </ItemTemplate>
                                </telerik:GridTemplateColumn>

Code to fill grid dropdown

Protected Sub myRadGrid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles myRadGrid.ItemDataBound

If (TypeOf e.Item Is GridDataItem) Then

Dim item As GridDataItem = CType(e.Item, GridDataItem)

Dim options As DropDownList = DirectCast(item.FindControl("ddlModel"), DropDownList)

Dim field As String = e.Item.Cells(5).Text.ToString.ToLower

sql = "Select dm.intModelId, m.strmake + ' ' + dm.strModel Model from Drat_Model dm INNER JOIN Drat_Make m on m.intMakeId = dm.intMakeId Order by strModel"

buildDD(sql, options)

'options.SelectedItem.Text = DirectCast(DataBinder.Eval(e.Item.DataItem, field).ToString(), String)

End If

End Sub

Error

DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'optiplex 760'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'optiplex 760'.

Source Error:

Line 95:

Line 96: buildDD(sql, options)

Line 97:             options.SelectedItem.Text = DirectCast(DataBinder.Eval(e.Item.DataItem, field).ToString(), String)

Line 98: End If

Line 99: End Sub

but if I comment out and then populate it works and the Optiplex 760 is in the dropdownlist and is also the same as the field Exist_Model.

RadGrid & RadToolBar - Object Reference Not Set To An Instance Of An Object

I have a grid that is by default grouped into 1 grouping upon page load. This is accomplished in the Page_Load event as in the following code. I had to do this because if using the client-side settings for grouping, when exporting, the group names do not show up in an exported ExcelML format.

If Not IsPostBack Then

rgWeightBreaks.MasterTableView.Columns(2).Visible = False

rgWeightBreaks.MasterTableView.GroupByExpressions.Add(New Telerik.Web.UI.GridGroupByExpression(rgWeightBreaks.MasterTableView.Columns(2)))

...

I have a toolbar that changes the grouping of the grid. If I don't do anything in the grid such as expand a group, these buttons work flawlessly. However, if I expand a group and then try to use one of the buttons, I get "Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object."

Here is my client-side code:

<telerik:RadScriptManager ID="rsmWeightBreaks" runat="server" />

<telerik:RadSkinManager ID="rskmWeightBreaks" runat="server" ShowChooser="false" />

<telerik:RadScriptBlock runat="server" ID="rsbWeightBreaks">

<script type="text/javascript">

args.set_enableAjax(false);

bExporting = false;

}

Migrating from ASP.NET to ASP.NET AJAX

Hi,

Im doing migration from ASP.NET Q3 2008 to ASP.NET AJAX Q1 2012 (both 4.0 Framework). How can I convert it? Does the dragging of RadScriptManager to existing page will convert it to ASP.NET AJAX? It did change some items on my web config but it looks like it doesnt run as ASP.NET AJAX. The Live samples has some port # in localhost when it is run, but my existing project has same localhost as before. And comparing their web config, has a huge difference. Any step by step info for dummies like me would be a great help.. What will happen to old rad dll? Thanks in advance..

adjusting radtextbox height when expanding radwindow

I have a radtextbox in a radwindow and I want to be able to expand the height of the textbox as the user resizes the radwindow. I have the textbox set up like so:

<telerik:RadTextBox runat="server" ID="configData" TextMode="MultiLine" Width="100%" Height="300px"/>

When I adjust the width of the window the width of the textbox will also expand so my first thought was to set the height to a percentage value however this did not work.

Is there a way to achieve this functionality?

Thanks
