Questions on UI for ASP.NET AJAX Forum

I am using Telerik ajax controls in VS2010 asp.net web project.
I am only targetting IE v8 browser.

When I encounter server side code exception, I get an error dialog box "There was an error in the call back."

When I click okay, nothing happens at the server side and code stops executing.

In this web application, there is no try catch exception handling any where. All the exception bubble up to Application_Error in global.asax.
In this specific case, how can I bubble up the exception to Global.asax?

Please help.

Thanks

Font formatting not being applied FONT tag vs SPAN tag in Design/HTML view

Hi All,

After installing the new version of editor (Telerik.Web.UI, Version=2012.2.912.40) hoping to fix some of the formatting issues I seem to have introduced more formatting issues. The problem is that if I type some text and try to change the font it does not change at all. When switching to HTML view I see following which appears to be properly formatted and all:

<span style="font-family: Courier New;">dfasdf asdf asdf asdf</span>

I have defined the editor as following:

<telerik:RadEditor runat="server" ID="richText" EditModes="Design" ToolsFile="EditorTools.xml" ContentAreaMode="Div" ContentFilters="ConvertFontToSpan,ConvertToXhtml,ConvertCharactersToEntities,IndentHTMLContent" StripFormattingOptions="All" Width="935px">

</telerik:RadEditor>

When inspecting html code using F12 Developer Tools I noticed that the content is still using FONT tag:

<FONT face="Courier New">dfasdf asdf asdf asdf</FONT>

Can anyone advise on this behavior? Has anything changed or have I missed anything?

Thanks

PS: I am on Win7 and IE9. Also see code discrepancy in the screenshot of the F12 tools

Crtical Suggestion : Gauge Ranges Naming

HI Support Team,

I Have Implemented The following gauge. I have Intialised the Gauge Ranges and there is no property to name the gauge range so that i can give from and to values from code behind. there is no online demo too for the alternative.

<div class="GuageBGImage">
<telerik:RadRadialGauge runat="server" ID="radTestDesign" CssClass="GuagePosition">
<Pointer Value="0" Color="#000000">
</Pointer>
<Scale Min="0" Max="100" MajorUnit="20" MinorUnit="5">
<MajorTicks Size="5" Color="#777777" />
<MinorTicks Size="2" Color="#777777" />
<Labels Position="Outside" Color="#000000" Font="bold 11px Arial,Verdana,Tahoma" />
<Ranges>
<telerik:GaugeRange />
<telerik:GaugeRange />
<telerik:GaugeRange />
</Ranges>
</Scale>
</telerik:RadRadialGauge>
</div>

I have set the values programatically as :
GuageName.Scale.Ranges[GaugeRangeSeries].From = value

But as there are around 28 gauges its really difficult to maintain in that way. Please give me suggestion to name Scale Tag and Range Tag.

Thanks,
Mady.

Rad grid Edit form Template not opening on first time initinsert event

Hi,

I have a user control with update panel, which I am opening in a popup from my page. This popup has a Rad grid which is again in another nested Update Panel. I have Edit Form in this grid.
Normal Scenario: The popup will open and on click of Add new record in the radgrid I am getting Edit form. In this scenario it works fine.

Second Scenario: When the pop up is opened, it has values and the controls are disabled, I have to enable the controls on server side side with the Asynch Postback. Now once i try to Click on Add new record button in the grid, it fires the event but does nothing but if we click the same button again, it will again fire the event and this time it will open the Edit form but closes the popup. I dont want the popup to be closed.
Please suggest.

Thanks,
Gagan

Export Not working

Scenario:

Grid in Conditional Update Panel
Within a UserControl
On a SiteFinity Page
Custom Export Buttons within the PagerTemplate.

Events are not firing on the server side as I cannot declaratively add the Event Triggers.
Cannot use script mananger as it's on the SiteFinity Page not in this control

Events fire on the Client Side but do nothing when executed.

Clinet code is straightforward enough but does not error or work

function onClientExcelExportCommand(sender, eventArgs) {

var tableView = $find("<%= TransactionListGrid.ClientID %>").get_masterTableView();

tableView.exportToExcel();

}

Help is required.

Many thanks

Binding the RadGrid dynamically with RadEditor in javascript

Hello,

I have a RadGrid with 4 template columns.
1. ASP:TextBox
2. RadEditor
3. ASP:LinkButton (ADD)
4. ASP:LinkButton. (DELETE)

When we click on "ADD" button we are adding a new row next to the selected row. Same way we are deleting the selected row on click of "DELETE" button. This we are doing in postback by rebinding the RadGrid. We need to avoid the postback and Add/Delete rows dynamically in javascript. Please provide the solution. Please find herewith the sample code that we are doing in code behind.

FYI: we are using net framework 4.0 and the Telerik.Web.UI.dll version is v. 2011.2.915.40

RadGrid - Show Group Panel

Hi,
I am trying to use the show group panel, allowing a user to drag the column names into it, however it keeps throwing an error:

"Error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid group by expression: 'Group By' clause missing"

However if I define an item in the configuration manager it works, properly, So why can't I drag and Drop? :(
