Hello. We recently upgraded to the 2011 Q1 release and I am having some issues with the gridview.

1) The vertical scrollbar does not appear anymore.
2) Not all of the columns show in the property builder. The columns are displayed in the grid, but they are not in the list in the property builder. The ones that do not show up are custom columns.

I have a column with a RadGridView GridViewComboBoxColumn and would like that when I clicked on the line, this column will open the ComboBox.

It would be more or less doing this (radComboBox1.ShowDropDown ()) when I clicked on the line.

Telerik.WinControls.Docking and the 2011.Q1 version.

I am now going to work on a project that I haven't worked on for a year or so (my co-workers have), and that has caused some problems for me.

I have a new, fresh computer, and installed the Telerik 2011.Q1 components. My project make use of the DocumentManager and DocumentPane from the now obsolete Telerik.WinControls.Docking, so I decided to convert to RadDock, but it is easier said than done.

I cannot open my form in design mode because the Telerik.WinControls.Docking is missing. If I add a reference to the 2010.3 version of this dll (without installing the entire package) I get an error saying that Visual Studio has encountered an error and needs to close, could not load file or assembly Telerik.Wincontrols.UI version 2010.3.

In your article http://www.telerik.com/help/winforms/dock-upgrading-from-dockingmanager-to-raddock.html it says that I need to have both versions installed, but this article refers to versions older than mine. Is this the way to solve this?

Or is it a way that I can fix it in my code?

Programatically sort RadGridView and grid data

Hello There,
          I am working with RadControls for WinForms Q1 2010 from last 1 and half year.
         Now, My current requirement is that, I have remember the sorting of the single column of the grid and show it as same on next load time.
         I have able to remember the sorting settings of the particular grid column but I am unable to sort it programatically. I have tried to call events Grid_SortChanging and Grid_SortChanged by passing them the required information like following :

GridSortField field = new

GridSortField(_sortableColumn.ColumnHeading, RadSortOrder.Ascending);<br>                    ArrayList list =

new ArrayList(); ArrayList emptyList = new

ArrayList();<br>                    list.Add(field);<br>                    GridViewCollectionChangingEventArgs e =

new GridViewCollectionChangingEventArgs(this

.MasterGridViewTemplate, Telerik.WinControls.Data.NotifyCollectionChangedAction.Add, list, emptyList, 0, -1, String.Empty);<br>

this.Grid_SortChanging(this, e); void Grid_SortChanged(object sender, GridViewCollectionChangedEventArgs e) { }  void Grid_SortChanging(object sender, GridViewCollectionChangingEventArgs e) {  this.Grid_SortChanged(sender,new

GridViewCollectionChangedEventArgs(e.GridViewTemplate,e.Action,e.NewItems,e.OldItems,e.NewStartingIndex,String.Empty));<br>        }

and when I debug the code I found that When I programmatically sort the grid It able to pass the parameters to Grid_SortChanging which gets called but after that the event Grid_SortChanged doesn't gets called.
Can anyone please suggest me where I am getting it wrong. Any code may also be appreciated.

Thanks in advanced.

Regards,
Yogesh

Visual Drag Cues

Hi Guys

I have used the old fashioned MouseDown - DoDragDrop approach to allow drag and drop to occur between two treeviews in my solution. The drag operation captures the Tag of the selected node and the drop operation uses that Tag object. This is all working very well but using this method does not give me the nice visual clues I know the Teleerik treeview is capable of.

It would be great to be able to use these nice visual clues on the Treeview when dragging to show the user what was "under" the cursor but when I set Allow dragDrop on the source treeview (which gets me the nice visuals when dragging) I find that I am no longer dragging the Tag object but instead moving the entire subtree from the source to the target!

Does anyone know how to enable the nice visuals by themselves?

Regards
Ian

No Drag from a node's Image

Hi Richard

I've noticed that it is not possible to start a drag operation on a node if the mouse is used "NodeMouseDown" on the image in the node; the text of the node must be "NodeMouseDown" for the drag to start.

Do you know if this is a kown issue or is it related to the extra checkbox you helped me put onto my custom node the other day. I was speculating that the extra item in the element tree was screwing with the event somehow?

My NodeMouseDown event looks like this

private void tvAlphaWorkspace_NodeMouseDown(object sender, RadTreeViewMouseEventArgs e)

{

if (Control.MouseButtons == MouseButtons.Right)

{

workspaceContextNode = (RadCustomTreeNode)e.Node;

}

if (Control.MouseButtons.Equals(MouseButtons.Left))

{

workspaceDragNode = null;

workspaceDragNode = (RadCustomTreeNode)e.Node;

workspaceDrag = true;

if (workspaceDragNode.Text != "Executables")
