DateTimePicker wont update till it loses focus.

Using VB.NET new win form, drop a DateTimePicker Rad control on the form.

Run the app.

Click the dropdown and the calendar appears. Select any date and the calendar disapears but the value in the control is not updated.

If you then click another control on the form the value will update.

Using version 2010.1.10.308 of the RadDateTimePicker control.

It doesnt perform like a standard DateTimePicker control where once a date is selected it populates the controls text field with the selected date.

I am having the same exact problem with the RadSpinEditor control.

Hierarchical radgridview two way databinding

Hi, Having alot of troubles with this and hope you guys can give me some pointers how to resolve this.

I have a DTO that implements INotifyPropertyChanged that fires when a bool is changed. Ex:

                    private class IssueMessageGridView : INotifyPropertyChanged         
                    {         
                                 
            
                    
                        private bool _marked;         
                        public bool Marked         
                        {         
                            get         
                            {         
                                return _marked;         
                            }         
                            set{         
                     
                                _marked = value;         
                     
                                if (PropertyChanged != null)         
                                {         
                                    PropertyChanged( this, new PropertyChangedEventArgs("Marked"));         
                                }         
                                         
                            }         
                        }         
                        public event PropertyChangedEventHandler PropertyChanged;         
                    }         
                     

This bool is databinded to a checkboxcolumn.

This I will use to multiselect rows from child grids. So when the user click on a child grid row, is will get marked. And then selects a row from another child grid view, this will get selected also. This is not supported in the radgridview.multiselect property.

I updated the Marked property on the IssueMessageGridView in a selection changed event fired method. But when the selection to another child grid view, the unselected grid is not updated even when the PropertyChanged event is fired on that object.

How do I update a child grid view thats not selected..?

Regard Harald

Custom context menu replaces filter menu

Hello,

if I use a custom context menu it replaces filter custom menu, too. But I want to use default filter menu and custom grid menu togther. In my opinion there should be a distinction between grid context menus.

There should be 4 different context menus:

- row menu
- column header menu
- row header menu
- filter context menu

I use custom context menu to define actions on databound grid item ( open / copy / delete... )

I use 2009.3.10.108

Regards,

Markus

Cannot use tab to move away from Textbox when the texbox is in TabStrip

Hi,

I'm using Telerik RadControls for WinForms Q3 2009 SP1,.net 2.0 and Visual Studio 2005. I have a windows application which contains a form with a RadTabStrip containing several RadTextBox. Whenever I press "Tab" in a textbox I heard a beeping sound and the focus does not leave the textbox. "Tabbing" behaves normally (move control to another control on the form) whenever the textbox is not within a RadTabStrip. Any idea?

Thank you.
Celia

Grouping/Sorting changes GridView row number, but not DataSource's

I've got an app that does the following:

1) Load a DataTable with info
2) Attach the DataTable to the RadGridView
3) Runs a threaded, long process using a BackgroundWorker object.
4) Since it's using a separate thread, I update the rows with new information via the DataTable object using the row number as my identifier to know which row needs updating.

This is all fine until the GridView is grouped. If I group, then run the same process, the row number for the GridView has changed, but not for the DataTable object. How can I get them the same so I know which row to update?

// this.colorForm.SelectedHslColor = (HslColor)currentTheme.ThemeProperties["BaseColor"];

// return;

//}

HslColor baseColor = HslColor.FromColor(Color.FromArgb(250, 0, 0));

//this.colorForm.SelectedHslColor = baseColor;

currentTheme.AddColorBlend(

"BaseColor", baseColor);

}

Issue with combobox in AutoCompleteMode Append

Hello
I added a RadComboBox to a WinForm with AutoCompleteMode = AutoCompleteMode.Append. In the SelectedIndexChanged Event I have this Code:

    
            Console.WriteLine(radComboBox1.SelectedValue);

In the Form_Load method I have this:

    
            IList<MyObject> orte = new List<MyObject>();     
        
            orte.Add(new MyObject(1, "aaa"));     
        
            orte.Add(new MyObject(2, "bbb"));     
        
            orte.Add(new MyObject(3, "bbb"));     
        
            radComboBox1.DisplayMember = "Ort";     
        
            radComboBox1.ValueMember = "Id";     
        
            radComboBox1.DataSource = orte;

I start the application, then I select the second bbb entry with the mouse. Then I press the tabulator key. The combobox then will select the first bbb (SelectedValue is 2). In AutoCompleteMode None it works fine.
Is there a workaround for this?
Thank you
