Hi I have following tree structure with checkboxes. I wanted to read the child notes selected or unselected and based on that I want to update a string which store those values

Tree structure

Parent1 ((checked))
         --Child11   
         --Child12 (checked)
         --Child13 (checked)

Parent2(checked)
         --Child21 (checked)
         --Child22
         --Child23

Parent3 (checked)
         --Child31
         --Child32 (checked)
         --Child33

Dim ParentsNodes as string

Dim ChildNodes as string

I want to loop through entire node with any check or uncheck event and update my ParentNodes string and ChildNodes string so that it says

ParentsNodes = "Parent1, Parent2, Parent3"

ChildNodes = "Child12, Child13, Child21, Child32"

How do I loop through my nodes in RadTreeView using VB.NET and in what event should I put this loop so that any check or uncheck updates my strings. Please help

Thank you!

Actually current i am working on a project that needs to import /export/manage a very large word document in Rich Text Editor. 

In this project user imports a word document of approx. 50 pages and then make some changes and the it saved to sql server database.

Now user can load it from database and further make some changes and again saved to database.

On importing the large word document it successfully imported in Rich Text Editor but after making some changes,

when i export it to a file then got the error "object reference not set to an instance of object".

Export functionality is working fine for small documents(approx 10 pages).

I am using this code.

Dim pathSource As String = Application.StartupPath & "\FileName.docx"
Using fsSource As Stream = New FileStream(pathSource, FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite, Int32.MaxValue, True)
                        provider.Export(document, fsSource):  '(error raised after executing this line of code.)
                        Dim docByte As Byte() = New Byte(fsSource.Length - 1) {}
                        fsSource.Read(docByte, 0, System.Convert.ToInt32(fsSource.Length))
                        fsSource.Close()
                        SaveFileToDatabase(docByte)
End Using

Please help....

Hello,

RadGridView supports self referencing hierarchy mode to mimic multi-column TreeList behavior. Is it possible to do the same with VirtualGrid?

Hi,

I need a control like windows TabControl for my project. For the radRibbon, I cannot make it dock to the whole layout and have full page tab containers where I can put all of my contents. I need same functionality like TabControl.

Medical App is providing the same functionality of tab which I need.

Thanks

I would hide a column before copy selected items.

Generally I use first column as Icon, but I have to remove it before copying.

How can I do?

Is exists a specific event to use before call Copy method?

radDock Position = Fill, Top, Bottom......

I want the loaded form will be in floatting mode without drag and drop it in the radDok.

I tried with the below code but I am not satisfied:

Hi, 

I've used your demo solution to understand how cell border color errors works.

I've found a bug if you populate your gridview with enough data to have a vertical scrollbar.

When you scroll down enough to hide first rows, when you scroll up to see the rows, it seems there's a glitch on some cells like you see in the screenshot.
