EDIT: Sorry, as I typed this I got the answer...

Hi *,

I have a Webpage that contains a RadOrgChart and RadToolTip-Manager. The Content of the ToolTip is based on the ID given from the RadOrgChart. It works fine until... the session times out.

The Response as soon as the Session times out is:
RadToolTipManager response error: Exception=Sys.WebForms.PageRequestManagerServerErrorException: Value cannot be null. Parameter name: source

I've already added an check that the control should not load then the Value is null.



There are no MS AJAX update panels on the side - I use the RadAjaxManager instead. The GroupItemDataBound-Event is added in the Page_Load and the UserControl loads the Content based on the ID (it loads nothing if no ID is available).
It is no big deal if the Session times out and the ToolTip-Content is not correctly loaded but I need to get rid of the error message and somehow I can't manage that.

Any help would be appreciated. I don't want to hack a 'Session-Keep-alive' or something.

Regards,
Gaby

Hi,

   I am looking for a control like asp:Repeater but with right to left support.

   Currently, in all such controls (Repeater, DataList etc)  the first item comes on the top left, and then on the right side (or first in second row), but i want it to have first item appear on the rop right side and then on the left of it. and so on.

    So basically, it should render items in reverse orders. Is that possible? Does any telerik control support such thing?

     thanks,
     Sameers

Hi,
I tried to use the RadAjaxManager with the wizard control but there are some things I do not really understand.
1. Does the configuration dialog for the AjaxManager only work in the currently selected WizardStep?
2. If you declare some new AjaxSettings for controls in other wizard steps is it possible that those controls are not rendered correctly because the AjaxManager creates Panels around them which do not have the same settings as the controls?

Would help me a lot to know that.

Best regards
Ferdinand

This issue is fixed in Q1 2013 SP1.

In Q3 2013 Firefox and Chrome freeze when a container with a select element is made visible with JavaScript and RadFormDecorator is present on the page. You can follow the issue's progress here.

The issue will be fixed for the upcoming Q3 2013 SP1. For the time being possible workarounds are:

• Setting the ControlsToSkip property of the RadFormDecorator to "Select".
• OR placing the provided JavaScript code from the attached archive below the declaration of the RadFormDecorator.

Sample scenarios that reproduce the issue are:

• Expanding an inner item from a RadPanelBar. The RadPanelBar has multiple Items that contain select elements and a RadFormDecorator is present on the page.
• JavaScript is used to set the display property of a container with a select element to "block" for example, multiple containers with select elements are present on the page and RadFormDecorator is used. For example:

JavaScript:

ASPX:

I am using a RadGrid that uses an EditForm for editing and adding items to the grid. The EditForm is a pop-up, template, and has the modal property set to true. I’m using Internet Explorer 9 and the pop-up works fine with the background grayed out, but when I switch to compatibility mode the background and the pop-up are both grayed out. The user can’t click or input anything at that point. I'm using .Net 3.5.

Any ideas of what could be going wrong?

It seems to me the user story below would have been done before many times by others so I am just trying to see if anyone knows of an example or such before I start down this road.. so I can save time...


User Story
1. A user will be uploading an excel workbook to our server.
2. We will then bind this workbooks data to a radgrid (number of columns will vary)
3.The user will then need to map each column in the radgrid to a set of corresponding data columns in our database.
4. Once the user has selected a mapping for each column (it is possible to ignore some) they will submit to our system for validation and import.
Now in step 3 I will need to provide a means to provide a combo dropdown in the header row that contains all of the database mappings for this import process... 
For example they could be (Ignore, First Name, Middle Name, Last Name, Cell Phone, Address 1, Address 2, City, State, Zip, Custom 1, Custom 2 and etc...) then the user would map each column in the radgrid to a column

Has anyone done something similar that they can point me to so I can read about it.. I just don't want to reinvent the wheel.....

NOTE:  It would be nice to include the header row in the excel workbook (if provided - user will select top row is a header row) in the radgrid with the dropdown also...
