I've got a hierarchy gridView in my winform that allows the user to pick items to include. 
In the hierarchy the parent is a "category", and the child rows are "category items".
In the grid, there's 2 columns for both the parents and children: a checkbox (Include?) and a textbox ("category name" for parent rows, "item name" for child rows).

The checkbox in the parent row in the grid is equivalent to a "Select All" at the top of a grid used to check all items, but instead of checking all items in the grid, when check, only the checkbox of it's child rows should be checked.  This way the user can pick individual "items" to include, or all items in a category, by clicking one checkbox.

The primary problem I've had with this is that when a parent row checkbox item is checked, the checkboxes of that category's child rows don't get checked until a second checkbox in the grid is checked.  It's like the checkbox checking/unchecking isn't actually performed until another event fires. 

I've tried handling this in rowChanged, valueChanged, CellEndEdit, CellValueChanged, and other events, and they all seem to do what I want in debugging, but the visible checking of child row checkboxes doesn't happen when it should.

I'm opposed to posting any of the code I've tried since I've tried so many approaches and just seem to be going round and round,  but will instead put it in pseudocode format.  So here's what I'm trying to accomplish:

Private Sub gridItems_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles gridItems.ValueChanged

 

 

    'If the changed item is a parent row checkbox Then

 

 

 

        ' For each childRow in currentRow.childRows

 

 

 

            ' childRow.checkboxColumn.checkboxEditor.Value = currentRow.checkboxColumn.checkBoxEditor.Value

 

 

        ' Next

 

 

 

    'End If

 

 

 

 

End Sub

 

 

 

Thank you in advance for any suggestions and advice.
Dan

I am attempting to use the CellValidating event.  I am encountering two problems.  First e.RowIndex is coming back as a -1 on the a new first row.  The row has been added using data binding.  Question, how can I find what row I am working with.  Second, I attempt to update the value (e.Row.Cells(1).value = "99213"  in a cell to the default, and the data does not show in e.Value.

Respectfully,
Dave

Hi,

I need to have a grid which can simulate the pivoting behavior of a pivot grid. I know Telerik does not have a pivot grid in Winforms, but would like to know if such a thing can be implemented somehow.

In the snapshot attached, pivoting has been done on 2 columns "Designation" and "Age". The remaining columns can either show the count of values or the sum of values.

Hoping for your help,

Thanks and regards,

Nihar.

Hi there,

I have been looking at the RadScheduler for WinForms (Q3 2010), and noticed that there is a TimeZoneInfo class inside Telerik.WinControls.UI.

Using this class it appears I can convert between Time Zones used in the .NET Framework, which is very helpful.

However, the target framework for my project is .NET 2.0 - which normally does not have this functionality (Microsoft only introduced the ability to convert between time zones in the TimeZoneInfo class of .NET 3.5).

So, have Telerik completely re-implemented the TimeZoneInfo class of .NET 3.5 so it can be used in .NET 2.0?  

Is this class as accurate as the one in .NET 3.5?  I would just like a bit more information about it.

Regards,
Eddie

Hello guys,

I am having a problem with the shortcut control. I want to assign a shortcut key for a radbutton within a radform
so i added a radbutton and a shortcut control in the radform. 

In the shortcut control i add input bindings for the radbutton
-  Chord       == CTRL+N
-  Command == ActionCommand
-  Context     == radbutton1

so its suppose to fire the click event for the radbutton. but sadly im not getting any response.

So i tried another control which is the radtextbox doing all the same procedure as i did for the radbutton. the only difference is the
input binding command == FocusCommand. Surprisingly when i press the shortcut for focus which is (CTRL+F) the textbox was focused successfully?

Am i missing something? What are the possible solutions/workaround for this problem. i attached the source code.

BTW i am using Winforms Q3 2009


Here is my source code

How can I ensure that a Form that has been docked to an MDIForm doesn't get docked a 2nd time?  That is, I need a Form to only be visible once.  I tried making it a singleton class, but calling the DockControl of the RadDock still added a same form , though one was an empty shell.
