I have a need to allow the user to delete multiple rows in a grid that is unbound based on their selection. The problem is that even though the grid is set with the following attributes:

SelectionMode: FullRowSelect
MultiSelect: True

And the rows appear selected via the control key + the mouse click on the row, the row .IsSelected property does not get set to true, it is always false. However, display wise on the screen the rows selected by the user appear to be selected with the orange highlight for the row.

The code that handles the deletion looks like this, the method that calls this block is via a context menu:

           int rowSelected = radGridView.SelectedRows.Count;

            if (rowSelected > 0)
            {
                int rowCount = radGridView.Rows.Count();
                for (int x = rowCount - 1; x >= 1; x--)
                {
                    if (radGridView.Rows[x].IsSelected)
                        radGridView.Rows[x].Delete();
                }
            }    

If the rows are set programmatically via the radgridview.Rows[x].IsSelected value to true, but of course I don't know what the user is going to select or unselect prior to the code running, so that is not an option when loading of information into the grid. Is there some other event that should be called to set the row when the user clicks on the row header, if so what is the property or event that needs to be handled?

I also tried this on handling the SelectChanged event on the grid. But no matter what happens the row.IsSelected property remains false:

private void radGridView_SelectionChanged(object sender, EventArgs e)
        {
            GridViewRowInfo ri = radGridView.CurrentRow;
            int rowIndex = ri.Index;
            if (rowIndex >= 0)
            {
                bool selectedRowState = radGridView.Rows[rowIndex].IsSelected;
                bool updatedSelection = (!selectedRowState);                                                   // sanity check for value
                radGridView.Rows[rowIndex].IsSelected = updatedSelection;                            // value stays false even after setting to true?
            }
        }



Thank you.

I created a RadContextMenu and added it to my RadGridView, but the menu appears to have no theme. It doesn't look anything like the default menu and the ThemeName is blank.

I tried this but the the RootElement doesn't seem to have a ForceApplyTheme() method anymore.

Hi guys,
This is how I use this event. It worked fine in Q3 2011.

Since I started using Q3/2012, this event doesnt seem to work anymore. Any suggestion?

Hi.  I'm working with the winforms chartview and exploring what it can do.  I've noticed that If I scroll and zoom my chart with control/mouse-wheel and click/drag operations, the labels fly off the X axis and start scrolling with the chart... I've attached a pic and some code.

Ideas?

How do I get the RadTextBox to respond to the Return key by moving to the next control on the form?

I have a grid anchored on all sides in its container (radPageViewPage).

I have set 
    AutoSizeColumnsMode = Fill
    AutoSizeRows = False or True
    HorizontalScrollState = AlwaysShow or AutoHide

However, the Horizontal Scroll Bar is *never* shown.

However, when I set
    AutoSizeColumnsMode = None

The HSB is displayed. However, the behaviour is erratic when I also set 
    AutoSizeRows = True

because when I change the size of a column, the width of the grid changes.

Because some of the columns have a minimum width, the fact that the HSB *never* is displayed with
   AutoSizeColumnsMode = Fill
even when some of the columns are hidden, seems like a bug to me.

How can I sort the child nodes of a particular node?

I want my RadTextBox to undo the current changes when the user hits the Esc key.  I am using the OnKeyUp event of the RadTextBox.

However, unlike the standard Windows Forms text box, there is no Undo method on the RadTextBox.  Really???

Curiously, there is a CanUndo property on the RadTextBox...

How do I get the behavior I want?

I need to create one RadDropDownList control in which user can enter only digits but not characters.
Hope I Will get answer soon, Thanks

e.NodeElement.BackgroundImage = myImage;

See attached image. I want to place this extra icon to the right. Something like "Right-align background image!". Is this possible?
