Hi.

I made tool window to floating. 

private void MakeDefaultToolWidow(string title, RadForm from)
        {
            ToolWindow newTool = new ToolWindow();

            newTool.Text = title;
            newTool.CloseAction = DockWindowCloseAction.Close;

            from.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
            from.TopLevel = false;
            from.Dock = DockStyle.Fill;

            newTool.Controls.Add(from);
            newTool.DefaultFloatingSize = from.Size;

            CurrentDock.FloatWindow(newTool);
            CurrentDock.ActiveWindow = newTool;

            from.Show();
        }


And, I docked this toolwindow to top(or anywhere).

At this time
CurrentDock.FloatingWindows.Count is 1.

And I Undock that toolwindow.
CurrentDock.FloatingWindows Count is 2.

Now Some button click and run belows.

foreach (FloatingWindow floating in CurrentDock.FloatingWindows)
                {
                    floating.Hide();
                }

foreach (FloatingWindow floating in CurrentDock.FloatingWindows)
                {
                    floating.Show();
                }


Dummy FloatingWindow shown.
Dummy is will be diappear when I move it.



I think when toolwindow is docked, FloatingWindows.Count should be decreased.
and Floating again. it will be increase.


I want Hide/Show all FloatingWindows.


check it please.
Thank you.

Hello

I have made a Hierarchy radGridView (radGridView with a Template set) and it worked pretty well , but after upgrading Telerik to v.2014.3.1021 , A problem appears in using "MouseDown" and "Expand/Collapse"  rows.
I have set drag n drop commands in MouseDown event on the grid to drag a row and drop it...
Before upgrade , It was possible "expand a row by clicking on it" and "Drag n Drop" both.
but after upgrade , Expanding is not possible ; clicking on the rows calls MouseDown method , and will not expands the row.
Is there a solution to solve it?
(VS2010-Telerik 2014.3.1021)

Kind Regards

Hi Telerik,

Is there a way to consult the "old What is New" webpage for older release of Telerik ?

The full log in release is history is really complete.

But if you have jumped one or two version (or when you update an old project) and just want to have a quick look to the new functionality the What's New is faster.   

Hello,

I'm trying to figure out how to use the Telerik.WinControls.Data.ObservableCollection.CollectionChanging event to detect when a user moves columns in the grid.  How can you do this in Visual Basic.NET?  I need to do this so I can detect if we need to save the layout for that user to the database or not.

Kind regards,

David

Hello,

I'm using a GridViewComboBoxColumn with DropDownStyle = DropDown, but the underlaying RadDropDownListEditor don't assing the typed text from text area into cell value. Only entries from the list are placed in cell value. Datasource behind the combobox is a List<string>. I want do two things:

a) Get the editor working to assing also value not placed in list to cell value
b) Get text from editor text area to be able checking agains data list and adding to list for next use of editor

How can I do this whit RadGridView:

For i = 0 To DataGridView.Rows.Count() - 1
    DataGridView.Rows(i).Cells(18).ToolTipText = "Target: " & DataGridView.Rows(i).Cells(24).Value
Next

With the latest release of the telerik controls the Radbutton has a weird UI glitch when the TerliekMetroBlue theme is applied.

Image 1 and Image 2 has the Button enabled at design time and is working as expected.

Image 3 and Image 4 has the Button disabled at design time and is not working as expected.

I just upgraded to Telerik UI for WinForms 2014 from 2010.

I have an application with about 40 grids we build dynamically that have checkbox columns. Many of the tables feeding these grids have NULL values for the bit column. When applying a filter to a grid that has NULL values in the CheckBox column I get an error. If I modify my query using ISNULL(fieldname, 0) AS fieldname I am able to filter, but I can no longer update the bit field for that CheckBox column because it is now aliased.

Before the upgrade the filtering worked even if there were NULL values. What can I do to get both filtering and update capability on CheckBox columns that reference a bit column that contains NULL values. The underlying data cannot be changed to eliminate NULL values because a NULL represents a state other than true or false when handling data in our stored procedures.

This is the code used to create the CheckBox columns:

ElseIf objTab.Columns(i).DataType.Name = "Boolean" Then
Dim col As GridViewCheckBoxColumn = New GridViewCheckBoxColumn
col.Name = colname
col.FieldName = colname
col.HeaderText = colname
col.ReadOnly = Not (pCanWrite)
objGrd.Columns.Add(col)
