My linq expression:

 

returns an iterator like this:

System.Linq.Enumerable.WhereSelectArrayIterator<P0300_DAL.Data.AnyObject,<>f__AnonymousType0<string,string,string,string,string,string,string>>

If I bind this as datasource to a radgrid everything works fine. But when I bind it to an radtreelist, the columns were generated but the content is empty.

Do I have to do more than: 
?
Here is my treelist declaration:

hi,  i'm using a physical path with radexplorer, as mentioned in the kb article.
how is it possible that the radexplorer has permissions to access the folder even if i don't set any special permissions to the folder?

Hi,

We are trying to create a link button that will be used in a telerik grids edit template to launch a document that is stored in the database as a binary object. The issue is we have an encountered an error when the linkbutton is fired and runs the command in the item_command for the radgrid it errors out. We narrowed this down to being an issue with the response.Write so we were going to try the methods that were recommend in previous posts on this issue.

When we registered the control as a postbackcontrol with the scriptmanager it will not fire the command in the radgrids item_command method. The control is created in a seperate c# file from the radgrid and we need to know the datarow in order to pull the appropriate binary data for displaying the document.

Any help would be greatly appreciated,
Jonathan

I have a date input where a user can choose to enter a date and time, or they can click on a button to load the current date and time.  I would prefer to set the value with client-side code if they click the button, but I cannot get it to work.  It will enter the current date, but not the time.  My control looks like:


If I click on the button, the results will have the right date but not the time.  For example, if I run it right now I get "02/11/2011 00:00" inserted in the raddateinput field, while the alert shows "toDay = Fri Feb 11 15:56:36 CST 2011".

If I remove the OnClientClick parameter from the button, it will execute the server-side code that I have coded for the button.  It looks like:


The results are now '02/11/2011 15:57".

How do I need to code the client-side code so that it properly loads both the date and the time in the control?

Thank you!

Hello,

I have what is most likely a common scenario and I'm sure there's a solution lingering in these forums that I can't find.  I have a RadTabStrip and corresponding RadPageViews.  The content of each PageView is a UserControl on which is a RadGrid.  Each RadGrid has a RadToolBar within the CommandItemTemplate.  Here's my use case.  On tab A, user selects a bunch of rows on the grid and clicks the toolbar button "Move to Trash".  This in turn removes these items from the RadGrid on tab A and moves them into the RadGrid on tab B.  I would like to use the RadAjaxManager and specify that the grid on Tab A should update the grid on Tab B.  Given that these controls are logically seperated using UserControls, the RadAjaxManager does not see the other grid as an updatable control.

It's extremely important that these grids remain on seperate user controls so their corresponding code is logically seperated from each other.  I also do not want to update the entire TabStrip as that will cause huge performance issues.  Is there a solution to this?

Thanks,
Chris

Telerik Team,

Hi,

I am trying to add a dropdown column in the edit form of a RadGrid that is bound to an ObjectDatasource and populated by a WCF Service and using the Entity Framework for Data Access.

Sample: Item has a Item Type Foreign Key.

I can display the text of the foreign key in the RadGrid by using the GridTemplateColumn and Eval("{ForeignKeyEntity}.{DisplayValue}"). I can also display the dropdown column in the edit form but as soon as I change the selected item and I update the row I get a script error where the selected value cannot be converted to a EntitySet.

Can someone please help me with a sample of the proper way to edit the Foreign Key items on an entity using a object datasource.

Thank you,
