Automatically Create Hierarchy from Item Data

Hello,

I'm trying to bind a treeview to a list(of CustomClass) where the custom class has "StartTime" and "Group" properties.

Is there some way I could group (into a node hierarchy) by the date parts of the start time? So, at the top level would be "StartTime.Date", that would expand to show all values of "StartTime.Time" for that Date, then those would expand to show all values of "Group" for that start date and time - that kind of thing?

Thanks,

Mike

RadGrid inside a FormView: Saving Data to DB with EF

Hi, here's the situation:

I have an asp:FormView w/ its corresponding ObjectDataSource and a bunch of fields. One of these fields is a usercontrol which contains a RadGrid and an associated ObjectDataSource. On the backend, I'm using entity framework 4.1.

Let's say I'm display a project in the formview. This project has several clients. The RadGrid is displaying the clients associated to the project and their information.

I have a save button at the top of the page to save all the information when I am in edit mode on the formview. In addition, when the formview is in edit mode, the RadGrid is also in edit mode.

When I click on save, I call the FormView.UpdateItem method. This calls the updatemethod of the ObjectDataSource associated with the FormView, allowing me to save the data specified in the regular fields.

Now this does not allow me to save the information that is specified in the RadGrid.

I tried manually firing the Update command of the radgird, thinking it will call the UpdateMethod of the ObjectDataSource associated to it, but that didn't work.
I thought that a possible solution would be to add a Parameter of type "Object" to the Formview's ObjectDataSource, and then sending a datatable or similar in the ObjectDataSource_Updating event, but I'm not sure how efficient that is, or if it's the best solution (or if it's even possible).

So my question: Does anyone know how I can save the information in the RadGrid which is within the formview when I press the Save button?

Thank you.

Issue with page content type

Hi,

We were asked to perform functional test using QTP on an internally developed application. Currently, we are facing difficult time with the content type for return page. QTP consultant told us the issue we are facing was due to the wrong content type in the return page from the Telerik controller used in the code.

We are using the AJAX controls and Telerik always return content type of text/javascript for page with mixture of html and javascript. Someone told us the the correct content type should be text/html for this scenario.

Is this a bug of Telerik? What we should do in order to get the correct content type?

"SQL" Like Where Clause FROM RadFilter

I remember a few releases ago I was able to get an "SQL" where clause from the filter criteria. Has this functionality been moved? I see the save settings option but I don't think my users will understand base64. I would love to be able to use the filter do generate custom reports.

Telerik error on Dotnetnuke website

Hi,
When trying to access my site I am getting the error below.
From what I can find it seems to be related to a Telerik version mismatch.

Following previous examples, they suggested I look for <add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler, Telerik.Web.UI, Version=2007.2.1107.0, Culture=neutral, PublicKeyToken=121fae78165ba3d4"
        validate="false" />
      <add path="Telerik.Web.UI.SpellCheckHandler.axd" verb="*" type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI, Version=2007.2.1107.0, Culture=neutral, PublicKeyToken=121fae78165ba3d4"
        validate="false" /> in my web.config file although these two entries do not exist.
I tried adding them into my web.config file but it didn't make any difference.

Could someone please point me in the right direction?
I really need to get this site back up and running.

Thanks!
Shaun

RadGrid Filtering EnableLinqExpressions

We upgraded to 4.0 and now none of our filtering works correctly. I've set EnableLinqExpressions="false" on one page and solved the problems on that page/grid. Will we have to through our whole app and add & set this tag to every grid or is there a work around???? Additionally, there now seems to be issues with Grid formatting and conflicts with css??? Any clues? Thank you.

Ajax Panel and styles on a mobile device

I have some buttons that update a database and I have them in an ajax panel. When a user clicks the button it inserts a value in the database and then returns to change the command argument from the button as well as the style associated with the button. Basically an on off button but the style is not changing after the update on a mobile device.

Are there any issues with the ajax panel being able to update the style on a mobile device?

DataNavigateURLfields in Configuration Manager

G'Day Guys,

When I try to type a field into the DataNavigateURLfields in the Configuration Manager it does not persist, yet it adds it to the source code. Makes it difficult to rely upon the Configuration Manager when values that it puts in the source code are not reflected in the Configuration Manager itself. Even happens on a fresh project with one page and one RadGrid.

Here is a short YouTube clip to show what the problem is.

Expand video to full size and it is viewable.
