CRUD operations don't work with EntityDataSource

Hi all, I upgraded my webpages to NET 4 and i'm using the EntityFramework abilities, I working with Mysql database, cause i develop on php and .NET and using the Mysql .NET connector v 6.4.4 for Visual Studio 2010.
I tried to bind RadGrid (v 2012.1) with the EntityDataSource, it reads whole rows but CRUD operations on RadGrid didn't work, my surprise was CRUD works on original ASP.NET GridView with EntityDS. here is my default.aspx code.

For this example i created a database called entity_test and one table with 3 columns (test1,test2,test3) on my Mysql 5.5 server

I would like to use RadControls cause i have worked with them for 3 years.
Thanks all.

Server-side data binding with nested RadListView

I went through the demo of hierarchical RadListView, is there a way to do databinding in server-side instead of using SqlDataSource control?

Thanks.

Tooltip not working after page navigation

I have a Radscheduler and RadToolTipManager in an ASPUpdate panel. I set up my tooltip using the demo here http://demos.telerik.com/aspnet-ajax/scheduler/examples/radtooltip/defaultcs.aspx?product=tooltip . Everything works fine on initial page load. The data displayed can be filtered by using a dropdown box. When the data refreshes, the tooltips no longer work. If I navigate to another day using the calendar controls, the tooltips no longer work. On tracing the flow, I no longer seem to get to the AjaxUpdate method for the RadToolTipManager if I change the data from the initial page load. I cannot see the disconnect. Please speak real slow as i am very new to this. Thanks.

Postback RadWindow and refresh ajax panels in parent page. How to???

Hi all, I've red many thread about similar problems but I'm still quite confused...

I have a page with 2 ajax panels in a master-detail classic configuration. In the left one I have a RagGrid with the list of my users. When I click on a row, in the other ajax panel (on the right) I show the detail information of the clicked RadGrid row.

Now, I have 2 buttons in this page:

a button that opens a "Add new user" RadWindow to add a new user
another button inside the detail ajax panel and opens another RadWindow to add/modify detail information about the specific clicked row

What I need is:

when I click on the first button to insert a new user I would, on finish, close RadWindow and refresh both ajax panel in parent page to show the added user in the RadGrid
when I click on the second button to add/modify detail information about a clicked row, on finish, I would refresh only the right side ajax panel with the detail informations of clicked row

How can I managed this scenarious?
Which are the fondametal elements I need in both parent page and RadWindow page to get it works fine?

Thanks very much!

Feature Request - Reorder Columns on Server Side

Hello,

I think that it would be very helpful to have a .Reorder method for the RadGrid to enable column reordering on the server side. I know that there is a .SwapColumns method, but this doesn't provide the functionality desired, unless you loop through all of the columns and add swap the column position with every column until the column you want is at the end.

If I have a RadGrid with AutoGenerateColumns, and I have a TemplateColumn I want to display at the beginning of the RadGrid, and another TemplateColumn I want to display at the end, I have to add both columns to the RadGrid in the page load, and then in the PreRender I have to use the SwapColumns method to swap the column with each column next to it, until it is at the end. It would be so much easier if there was a .Reorder method where I could just pass the index of the column I want to move, and the new index where I want to column to move to.

Something like the following:

RadGrid1.MasterTableView.Reorder(RadGrid1.MasterTableView.GetColumnSafe("TemplateCol2").OrderIndex,

RadGrid1.MasterTableView.RenderColumns.Length - 1);

I would think that this would be more practical than using the SwapColumns method, since SwapColumns would just switch the TemplateCol2 column with whatever column was the last column of the RadGrid.

Thanks!
Casey

For Each rowItem As GridDataItem In rgNewTemplate.Items

RouteID = rowItem(

"RouteID").Text

[Solved] Changing success/fail image (red and green circles)

How can these images be changed? They used to be an x and a check box in older versions (a lot better) but are now just circles which causes accessibility issues for color blind users... how can we change the images to something else? I can't find a property and can't seem to overwrite the css.

Thanks in advance,
MS
