I downloaded and studied the example for implementing a DBContentProvider for the RadFileExplorer. Afterwards I decided to try my hand at it but have run into an issue that has me at a loss. When I add a subfolder to my root the file editor throws a generic windows.alert error messasge that simply displays the subfolder path. After dismissing the alert the file editor will refresh with the subfolder appearing in the right-hand grid...but it does not appear as a child node of the root in the treeview. If I click the 'refresh' button then everything is fine...the subfolder appears in both the treeview, as a child node of the root, and in the grid.

I opened both the example and my project in VS and set a breakpoints in the 'ResolveRootDirectoryAsTree' method of each. Running the repro steps I discovered that in my implementation the breakpoint is hit twice...once before the alert message box and a second after dismissing. Both times the path argument is 'Root/'. The same operation on the example code has the breakpoint being hit four times...
'Root/'
'Root/NewFolder/'
'Root/'
'Root/'

A close look at the 'DirectoryItem' generated in the method shows no differences...the full path and location properties of both the parent and it's child are the same for both my code and Teleriks. Tracing through the code shows nothing different either. So my question is this...where in the telerik code-base is this alert message being generated and what error condition is it intended to convey??

it is a standard window.alert message box with a title of "Message from webpage" and a subject of "Root/NewFolder/"...that's it, no error message, just the full path of the newly added subfolder.

BTW: to setup for debugging the issue I deleted all the example 'Items' but the root folder. Also my implementation uses LinqToSql to manage two tables...dbo.Directory and dbo.Content, rather than a single 'Items' table as the example does. For that reason posting code with this thread would be pointless.

Has anyone else seen this error dialog being thrown when adding a folder?? If so, any suggestions as to where to look??

Hi All,

I am using RadGrid control and creating one grid column programmatically but the problem is that when I use filter of that column it gives me an error radgrid is neither a DataColumn nor a DataRelation for table. I can view that column but when I try to filter the records using the date filter then it produces an error.

Also, how can I set the index of that column as I want to set the position of that column as number three because before that I have two more columns edit and delete.

Any help would be greatly appreciated.

Thanks in advance.


 

Hi team,
Language : vb.net
I tried search in your forum and all the examples given. Most of them, only show in c# not in vb.net.
And the function for onclick is not available ..except oncheckedchanged.
My problem is.

One more case :
If i use GridClientSelectColumn, how to add a function like on checkedchanged.

Can somebody guide me.

Hello!
I would like to show the full list search when clicked within the control RadSearchbox, is it possible?
Without having to type anything ...

I also wonder if the use ButtonCommand I could create different searches. Example: Clicking the Globe Button I would use the criterion X.
To Favorites I would use the criterion Y.
Using the functionality I asked above. Clicking already carry automatically, without the need to type anything ...

Hi guys

Using any tweak, can I open a Radwindow in another browser view? The scenario is I need to open a radwindow on clicking a link button, but the radwindow should be opened independently (it should not open in the current page containing my link button)

Thanks
