I have a hierarchical (rows + children rows) RadGridView. I'm already using the ViewCellFormatting event in order to display my own [+] and [-] images.

Is there a way to know if a "parent" row has no children rows the event handler, so I can set an empty image in the first place? That way the user has a visual clue that the row doesn't need to be expanded.

Hi,

I found a bug when adding a few input controls like textboxes etc on a form, in combination with the raddropdownlist (DropDownStyle = DropDownList). When pressing the tab key to focus the next control, everything works normally with the textboxes, but when the dropdownlist gets focus, there is no visual feedback to see which control has the focus. After manually clicking the dropdownlist, the tab key focus works as it should do.

Tested with the winforms product, version 2013.1 321 (mar. 21, 2013) on a Windows 7 machine 64 bit, with the VisualStudio2012Light theme.

PS, I wanted to add this bug in your tracking system, but the RadDropDownList is not in the selection where you should choose the bug-related control. This list could also be sorted alphabetically, which makes finding the right control much easier ;)

Hello,

i am having a treeview. and adding the nodes manually.
For Each ct In ChecklistTemplate
  
                newChecklistTypeNode = New RadTreeNode(ct.ChecklistTypeName, False)
                newChecklistTypeNode.Tag = ct.CheckistTypeID
                newChecklistTypeNode.LoadedOnDemand = True
  
                If (Not tvChecklists.Nodes.Contains(newChecklistTypeNode)) Then
                    tvChecklists.Nodes.Add(newChecklistTypeNode)
                End If
Next

i am checking whether the node is already present in the treeview.
suppose following nodes are already added in treeview
1. abc
2. xyz
3. pqr

if i now add xyz node in treeview the condition tvChecklists.Nodes.Contains(newChecklistTypeNode) returns FALSE.

Please suggest.

Thanks
Sachin

Hello,

I am trying to create an image reviewer where an image is displayed and reviewed.  Right now the image is displayed in a radDiagram as a radDiagramShape.

What I am trying to do is create a feature where a box can be moved over the original image and the portion of the image that the box is over be displayed in a separate shape object.  That way the user can have a "zoomed" look over the original image without needing to zoom and pan over the original image.

Can this be done?

Thanks for any suggestions!

I have a RadTreeView that has nodes listing directories and files from a certain location in the file system. Now if I were to go into Windows Explorer and manipulate one of the files, how can I update the RadTreeView automicatically to the user's action? Say if I were to delete the file, how can I refresh the RadTreeView to show that once they do it from Windows Explorer? Is there a way?

I created some columns, some with decimal values and some with Boolean values.

When I do the bind, every field is fine except the the one with Decimal and Boolean. All my Boolean values are checked, yet after the bind, they show as unchecked. As for the Decimal columns, they are not showing anything at all.

Hello Team,

We are currently building a POS app with winforms and we are wondering if the image attached (Solely the cart list, excluding the headers) can be reproduced?

If yes, how? Any help will be appreciated.

     Hello, 

i'm binding an observable collection of expando objects to a radgridview, each object is supposed to contain a boolean but since i'm constructing my expando object from a <string, object> dictionary the bool property is an object(bool), so when these are displayed with autogeneratingcolumns true i just get a text column with true or false 

 

how can i display them as checkbox ? 

 

Thanks by advance.
