Hi,

Perhaps someone can help me out. I am trying to do something that should be extremely easy with OpenAccess. Complex DataBinding to a textbox. I have not been able to accomplish this with OpenAccess. I have been trying this unsuccessfully for 3-4 weeks. Does anyone know how to do this? If so, could you please post some example code. I am using SQL Server Compact 3.5 and WinForms.

I can successfully add, update, and delete records from one table in a grid. Nothing else works.

Also, Telerik support has been terrible. They take many days to give an ambiguous answer. So far they are the worst support I have encountered. I regularly deal with <admin>company name removed</admin> and <admin>company name removed</admin>. Also, I have had great success with <admin>product name removed</admin> as an ORM. This product works very well however crud is painful (lots of code). This is why I was interested in OpenAccess. Telerik advertises it as great for CRUD. I'm hoping someone can help me before I throw this product in the garbage.

Hi,
How to Maintain the state(userid) of checked records  during paging in rad grid?
below is my code for reference.
and
Help needed,
Thanks

I posted this question on StackOverflow: http://stackoverflow.com/questions/26935565/cannot-read-property-length-of-null-using-sender-set-selectedtogglestateinde

It would appear that this telerik thread holds some relevance: http://www.telerik.com/forums/radbutton-javascript-error

Note this issue is in the same project as the RadCombo thread I made: http://www.telerik.com/forums/client-side-eventargs-are-mutable 

Where 'navigating' the client state (control state or view state) using either sender or the event argument is not an issue.



If you could answer this question on SO, I would be greatful, but I do have a general question for this thread post. What is the underline mechanics of how telerik uses the client functions 'get_selectedToggleStateIndex()' or 'get_toggleStates()'.. what is '_functionality' and why is it null in my implementation (i.e. nested function as a promptcallback function)?

Hi,

I'm using a GridTemplateColumn with an Image control in ItemTemplate. I'm using the ItemDataBound event to set the Image background, this all works fine. However when I click on a column to sort all the text columns are sorted correctly but the images do not move.

Here is my code:

ASPX:

NeedDataSource and ItemDataBound events:


Any sugest how I can fix that problem?

Thanks

I do not want the selected row in a grid to turn dark. How do I turn that off?

On Save, the changes made on the editor goes away leaving behind the original image loaded in rad image editor .
Secondly this works on My Local machine Very fine but when i deploy it on server the above mentioned exception occurs. i have also tried the solution posted in a thread to increase Json Limit but it does not do anything.

Hi,

I have the following situation: I have multiple self-developed Web User Controls (ascx) in my web application. The user controls are holding different logic, for example a rather complex contact form.

Every page's content on the website, is edited throud RadEditor. Now I need a flexible way to dynamically load page content including one, two, three, x of my own custom user controls....

How can i accomplish this in a neat way with the RadEditor?

My own solution is, in the RadEditor's contentarea, to insert a reference to the user control like %%control:MyFancyUserControl%%, and then at runtime search for %%control:MyFancyUserControl%% and load the control when the page is rendered.

How can I avoid the dialog box to save?
I want to save the image directly (AllowedSavingLocation="Server") without the dialog.
I'm saving my edited image to the database....
