Drag and Drop from GridView to TreeView

I need to be able to drag a row from a gridview over onto a tree view. I see an example but it's pretty old. I was wondering if there are any newer examples or better ways of doing it?

TIA - Jeff.

Inconsistent Behavior for ActiveWindowChanging event

I noticed that RadDock's (2010.2.10.914) ActiveWindowChanging event has some inconsistent behaviors:

        private void mainDock_ActiveWindowChanging(object sender, DockWindowCancelEventArgs e)
        {
            //Current: radDock1.ActiveWindow
            //Changing To: e.DockWindow
            if (radDock1.ActiveWindow != e.DockWindow)
            {
                //There are at least 2 documents in radDock1
            }
            else
            {
                //There is none or only 1 document in radDock1
            }
        }

It would be nice if DockWindowCancelEventArgs class would have both the current and the changing-to DockWindows information.
This is useful when you have a situation where a MDI application and documents having their own RadDock components. In this scenario, when switching between documents, it would be a good idea to hide any floating windows in the existing document before switching to the changing-to document. I don't think RadDock currently has anything for this purpose.

Solution for Horizontal Scroll Bar and Column Fill mode problem

Problem: You want the grid to fill up entirely so you use Column Fill mode so no empty space would be showing in the right side of the columns. In doing that, you loose the horizontal scroll bar when the grid's size is smaller than the sum of the column's width. There has been suggestion of using a scrollable panel to host the grid. But that solution is not ideal.

Solution: It is very simple. Just turn off the Column Fill mode so the horizontal scroll bar would be available when needed. Then we just have to do what the Column Fill mode is doing manually

Below is the code that I came up with: Subscribe to the grid's gridView_Resize() event so it would call FillWidth() when there is a resize event. Where ever in your code when you show the grid the first time, just call to FillWidth() so it would look right in the case that that gridView_Resize() event does not fire.

public void FillWidth()

{

if (gridView.ColumnCount == 0)

return;

var width = CalcColumnsWidth();

if (width < gridView.ClientSize.Width)

{

// get the remain empty space in grid

width = gridView.ClientSize.Width - width;

int extraWidthPerColumn = width / gridView.ColumnCount;

int i, limit = gridView.ColumnCount - 1; // stop before the last column

for (i = 0; i < limit; i++)

{

if (gridView.Columns[i].MaxWidth > 0 && gridView.Columns[i].Width + extraWidthPerColumn > gridView.Columns[i].MaxWidth)

{

// do calculation before we lost the original width

width -= (gridView.Columns[i].MaxWidth - gridView.Columns[i].Width);

gridView.Columns[i].Width = gridView.Columns[i].MaxWidth;

}

else

{

gridView.Columns[i].Width += extraWidthPerColumn;

width -= extraWidthPerColumn;

}

// the last column get any remaining width

gridView.Columns[i].Width += width;

// This only add to the last column

//gridView.Columns[gridView.ColumnCount - 1].Width += gridView.ClientSize.Width - width;

}

private int CalcColumnsWidth()

{

int width = 0;

foreach (var column in gridView.Columns)

width += column.Width;

return width + gridView.ColumnCount + 15; //take into the vertical lines between columns and vertical scrollbar

}

private void gridView_Resize(object sender, EventArgs e)

{

gridView.MasterTemplate.BestFitColumns();

FillWidth();

}

.

ShowUpDown on an GridViewDateTimeColumn

Hi,

I followed an example i found on this forum with this code:

RadDateTimeEditor editor = this.radGridView1.ActiveEditor as RadDateTimeEditor;

if (editor != null)

{

RadDateTimeEditorElement editorElement = (RadDateTimeEditorElement)editor.EditorElement;

editorElement.ShowUpDown = true;

}

This code are inserted into the event CellBeginEdit.
The problem is when i'm editing the cell. Since i have bounded this grid to a datasource i expect the value (Time) from the datasource to show up in this cell when i'm editing as well as when i'm not editing it.
But instead of showing the value, the value presented is 00:00:00.

The second question is, how can i modify this editorElement to only show hh:mm (ex. 11:30) when editing?

Regards
Svein Thomas

RadDateTimeEditor editor = this.radGridView1.ActiveEditor as RadDateTimeEditor;

if (editor != null)

{

RadDateTimeEditorElement editorElement = (RadDateTimeEditorElement)editor.EditorElement;

editorElement.ShowUpDown = true;

}I

Issue with custom XAxis labels

Hi,

I've got a RadChart that I'm building on the fly from a filtered binding source. It shows some values on the Y Axis and along the X Axis it shows the month number that the data corresponds to:

For example
20
15
10
5
1 2 3 4 5 6 7 8 9 10 11 12

Where 1 = january and so on.

Because I am not binding this to a datasource, but I am building the series and data on the fly, I cannot use the

Me

.RadChart.PlotArea.XAxis.DataLabelsColumn as far as I know.

However, I want to replace the X Axis labels with meaningful names I.e Jan Feb Mar etc...

I have tried adding this in during the loop and the labels show, but once the labels show, the data doesn't.

Please can you advise an easy way to get the X Axis labels to be set to a custom value

Thanks

Richard

RowIndex issue

Hello!

Was the meaning of GridCellElement.RowIndex property changed since 2009-Q3?

Please see the following code snippet:

01.public Form1()

02.{

03. InitializeComponent();

04.

05. radGridView1.Columns.Add(new GridViewTextBoxColumn("Group"));

06. radGridView1.Columns.Add(new GridViewTextBoxColumn("RowIndex"));

07.

08. for (int i = 0; i < 3; i++)

09. radGridView1.Rows.Add("Group 1");

10. for (int i = 0; i < 3; i++)

11. radGridView1.Rows.Add("Group 2");

12.

13. radGridView1.MasterTemplate.GroupDescriptors.Add(new GroupDescriptor("Group"));

14.}

15.

16.private void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)

17.{

18. if (e.CellElement.ColumnInfo.Name == "RowIndex")

19. e.CellElement.Value = e.CellElement.RowIndex.ToString();

20.}

I expect the following result:

Group 1

0

1

2

Group 2

3

4

5

But the result is:

Group 1

0

1

2

Group 2

0

1

2

It seems that the RowIndex is an index inside the group but not the entire grid. Could you please confirm this?

Is the following workaround correct?

1.int rowIndex = radGridView1.Rows.IndexOf(e.CellElement.RowInfo);

Thank you.
