GridBehavior

Hello,

how can i prevent to go in the edit mode if i click on a cell (not the current cell) in the current row with the mouse? i have tried to override OnMouseDownLeft:

protected override bool OnMouseDownLeft(MouseEventArgs e)
        {
            GridCellElement cell = this.GetCellAtPoint(e.Location);

            if (cell != null)
            {
                GridRowElement row = this.GetRowAtPoint(e.Location);
                if (row.RowInfo == this.GridControl.CurrentRow && cell != this.GridControl.CurrentCell
                    && e.Clicks == 1)
                {
                         this.GridControl.CurrentRow = null;
                }
            }

            return base.OnMouseDownLeft(e);
        }

This implementations unfortunately works with a restriction: the horizontal scrollbar jumps always completely to the left.

Thomas

[Solved] Missing FormClosing and FormClosed in RadDock

Hi,

a RadForm assigned to the RadDock is not sending the FormClosing or FormClosed event when i close the tab.

RadDock1.DockControl(form, UI.Docking.DockPosition.Fill, UI.Docking.DockType.Document)

Sometimes a have a lengthy operation and it is still running in the background when i already have closed the tab. Is there a good way to see from within the form if it was closed from outside? There is this TransactionCommitted event that gives me a RemovedWindow list when tabs are closed, but i don't know how to get back to the form itself. Is there a specific reason why the close events are not fired?

Thank you!

AllowAddNewRow when bound to LINQ datasource

private Unit u = new Unit();

u.setUnitContext();

IObjectScope context = u.context;

var q = from d in context.Extent<TblUnitType>()

select new { d.UnitType, d.Abbreviation };

radGridView1.DataSource = q.ToList();

When setting the grid.MasterTemplate.AllowAddNewRow = true; and upong adding a new row to the grid it throws an ArgumentOutOfRangeException... If a bind to a datatable everything works fine...

The question is how do I add a new row to the rows collection when the grid is bound to a "linq query".

Inconsistent built in Themes

Default themes are not listed in the Themes property of a few objects. I'm saying "few" because I'm only used Telerik for a couple of hours, so this is a pretty obvious problem if I was able to discover it this fast

-RadDock is missing Aqua, Vista, Telerik, Vista Black & Breeze at the very least
-RadMenu is missing Office2007Blue at the very least

How do I get all of the Themes added to the controls so users have a consistent set of colors?

Thanks

:)

Customized controls embedded in GridView

I try to embed RadCheckBoxElement to GridView in CellFormating event. My scenario is to show a RadCheckBoxElement in row "caption0". My Telerik controls version is Q1 2010.

    
                    void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)  
        
                    {  
        
                        if (e.CellElement.ColumnInfo is GridViewDataColumn && ((GridViewDataColumn)e.CellElement.ColumnInfo).FieldName == "Caption")  
        
                        {  
        
                            if (!(e.CellElement.RowElement is GridTableHeaderRowElement))  
        
                            {  
        
                                if (e.CellElement.Text.Equals("caption0"))  
        
                                {  
        
                                    if (e.CellElement.RowInfo.Cells["Value"].CellElement.Children.Count > 0)  
        
                                        return;  
        
                                    RadCheckBoxElement element = new RadCheckBoxElement();  
        
                                    e.CellElement.RowInfo.Cells["Value"].CellElement.Children.Add(element);  
        
                                }  
        
                            }  
        
                        }  
        
                    }

It seems that everything works fine without scrollbar.

However, if I scroll the scrollbar, a strange issue will happen. The RadCheckBoxElement will be embedded not only in row "caption0" but also in other rows. If I scroll the scrollbar several times, more and more RadCheckBoxElement will be shown in different rows.

Please refer to the attached images.

Could anybody help me? Thank you.

Changing Position in Grid after ObjectProvider.CancelAll

Hello,

I've a radGridView with an objectView as dataSource.
When the grid is sorted by a column, then, after executing the following command-lines, the objectView.position is changed. It doesn't matter, whether before there was changes in the data or not.

this.BindingContext[objectView1].CancelCurrentEdit();

this.objectProvider1.CancelAll();

This happens with the radGridView-Version 2010_Q2. In 2010_Q1 it was ok.
As a workaround i can store the postion-value before the CancelAll-method and set the old value after it. But i didn't need this to do in the last version of WinForms.

Regards

Roland
