Unable to render UI controls in grid after upgrading to lates telerik

Hi,

We are using radgrid and in itemdatabound we are using below code to get the text but when we are trying to read values we are getting "&nbsp". This started happening after we upgraded to latest telerik dll. we were able to read values with the old telerik dll. Is this a known issues if so what options do we have in reading the values of GridDataItem in ItemDataBound event.

Dim lblColumnName As Label = DirectCast(item.FindControl("lblColumnName"), Label)

lblColumnName.Text = item.Item("ColumnName").Text

Checkboxes - select all when paging is on

I want to create a databound RadGrid that with checkboxes in a column and enable a user to check/uncheck all boxes in the dataset, not just what's displayed on in the current paged dataset. So, if I have 6000 records but only 50 are displayed, I want to be able to Check/Uncheck All and have it check or uncheck all records, not just the 50 displayed. Then I want to submit this back to the database to update the records.

Javascript injection attack?

Is there a way to prevent a maliciously-named file from causing a Javascript injection? If you use a Mac (so that you're not bound by Windows filename conventions) and name a file with javascript in the file name, it's possible to cause the page to fire that javascript. I've already disabled the 'show filename' option, but it still is firing when I test this.

how to maintain the insertion point when I am loading a picture from a script fired from a custom control on the toolbar?

I am using Radeditor and have this scenarion where I upload picutres and insert them in my radeditor document.

I have a cusom button on the rad editor toolbar which fires the upload operation all in javascript on the client.
the picture uploads without postback, and in my script I try to insert it at the point where the insertion point was when the user clicked on the custom button that fired the whole operation.

The problem is that the picture is always, always inserted at the very begining of the document.

is there a way that I can maintain the insert position when I insert my picture?

this is very basic, in Radeditor i have a custom button deined and then it calls a javascript function:

<

script type="text/javascript">

Telerik.Web.UI.Editor.CommandList[

"Custom1"] = function(commandName, editor, args)

{

DoLoadNewPhoto();

};

</

script>

and then when my file uploads returns i insert it in the editor also with javscript like this:

var

str = '<img id="Tempdivphoto{1}" alt="" src="/BCW_Web/PhotoFeeders/GetNewTempForumPostPhotoThumbNail.aspx?ForumPostTempPhotoIndex={2}"/>'

var tempstr = String.format(str, temvt.get_Title(), indexcount, TempPhotoArrayIndex);

temvt.set_ObjectString(tempstr);

$find(Posteditor).setFocus();

$find(Posteditor).pasteHtml(tempstr);

but always it inserts at the top instead of where the insertion point originally was.

Dynamic Steps based on user input

I have a step in my wizard that collects basic information for the user AND the user's spouse but only if the user chose Include Spouse in a previous step.

One way I've thought of resolving this is by duplicating the step called Personal Details in the first one having the input controls for only the user and in the duplicate have input controls for both the user and the spouse. Then if the user chooses to include Spouse we can just hide/remove the unecessary step?

There doesn't seem to be anything in the API that allows you to affectively Switch Off steps and by that I mean they should dissappear out of the navigation and progress bars and the next button should know to skip them if they are switched off.

WizardStep.hide - just hides the content of the step
WizardSteps.remove - throws exception "TypeError: c.unselect is not a function" (Javascript)
WizardSteps.removeAt - same as previous exception

Create steps depending on user input in first step

Hi! I am trying to create HelpDesk functionality using RadWizard to create new incident.

On first step user selects incident category from RadComboBox (hardware problems, software etc)

Then i dynamically create 2 new steps with a different markup depending on combobox selected value.

Everything works fine until user goes back to first step and selects new RadComboBox value.

Functionality allows to do such thing. And i have to delete next steps and create new ones with other markup.

I found simple solution to disable RadComboBox, but it seems to be uncorrect solution. Can you help me?

Here is my code
