I am experiencing the follow problem with the MultiColumn ComboBox control.
First I setup the MultiColumn ComboBox as follows:

    
            CategoryRadMultiColumnComboBox.DataSource = _categoriesBindingSource; 
        
            CategoryRadMultiColumnComboBox.DisplayMember = "CategoryName"; 
        
            CategoryRadMultiColumnComboBox.ValueMember = "CategoryId"; 
        
            CategoryRadMultiColumnComboBox.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList; 
        
            RadMultiColumnComboBoxElement categoriesElement = CategoryRadMultiColumnComboBox.MultiColumnComboBoxElement;           

            categoriesElement.EditorControl.MasterGridViewTemplate.AutoGenerateColumns = false;        

            categoriesElement.EditorControl.MasterGridViewTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;            

            categoriesElement.EditorControl.MasterGridViewTemplate.Columns.Clear(); 
        
            categoriesElement.Columns.Add(CreateGridViewDataColumn("StandardId")); 
        
            categoriesElement.Columns.Add(CreateGridViewDataColumn("CategoryId")); 
        
            categoriesElement.Columns.Add(CreateGridViewTextBoxColumn("#", "CategoryNumber", 30, 30)); 
        
            categoriesElement.Columns.Add(CreateGridViewTextBoxColumn("Name", "CategoryName", 100));

On the SelectedIndexChange event of another ComboBox I set the filter for the datasource as follows:

    
            private void StandardRadMultiColumnComboBox_SelectedIndexChanged(object sender, EventArgs e) 
        
            { 
        
                        RadMultiColumnComboBox cbo = (RadMultiColumnComboBox)sender; 
        
                        _categoriesBindingSource.Filter = String.Format("StandardId = '{0}'", cbo.SelectedValue.ToString()); 
        
                        RadMultiColumnComboBoxElement categoriesElement = CategoryRadMultiColumnComboBox.MultiColumnComboBoxElement; 
        
                        if (categoriesElement.Rows != null && categoriesElement.Rows.Count == 0 && CategoryRadMultiColumnComboBox.SelectedItem != null) 
        
                        { 
        
                            CategoryRadMultiColumnComboBox.SelectedItem = null; 
        
                            CategoryRadMultiColumnComboBox.SelectedValue = null; 
        
                            CategoryRadMultiColumnComboBox.Text = " "; 
        
                        }             
        
            }

Now when the filtering results in 0 rows in the DataSource the Text property retains the previous value and I can not seem to clear it not matter what properties I change.

You see that the above xml is more complex than the xml file which supported the treeview (XMLSerialization demo).
So, I'm asking you as new developer of winforms to help me step by step in order to insert, update and delete records from the above xml.

If the treeview is not intended for supporing such xml files, Please, guide me how to achieve the requirement using another control.

It is appreciated to send me a code with an explaination.

Regards,
Bader

Telerik Theme works after mouse hover

Hi,
I have encountered some problems:
First, I change my grid's theme to Telerik, at runtime Column Headers's theme still remains unchanged but other parts are effected.
and the user have to hover mouse over the header to see the theme's effect on grid. this happens only one time, at form load.

Second, In a comboobox column the cell doesn't show the correspond value of combobox.

Third, While I have handled DataError, CellValidating, RowValidation Events, why still NoNullAllowedException and DupplicatePrimaryKeyException throws by the application? this happen when I click somewhere on the Form or Grid (this really happens just test it).

Fourth, Do I have to write code to change combobox column' Right To Left property for each Grid of My App?

And more unsolved problems in the near future,
Special thanks to Telerik Team, for lots of time you pay to me.

Parent Child with 2 Grids

Using the gridview controls is there a way to create a parent child relationship and all the grids to handle the table design that they are populated with. For instance if someone adds a row to the parent and that violates the constraints of the table will the grid display that or do I have to handle all of that on my own? When the user changes rows in the parent the child grid should automatically on it's own query the table and repopulate. Is this possible with telerik? My boss thinks the grids should act like the oracle forms or Access forms with the underlying datasource. Will that functionality work with Telerik Winform controls?

Thank You

RadMenu Item can't fully display in Win7

I use RadMenu in my Windows Application. If the application run in WinXP, the text in the menu item can be displayed completely.
However, in Win7, only part of the text is displayed (e.g. only "Men" is displayed instead of "Menu Item"). When the mouse over the menu item, it can be displayed (e.g. "Menu Item").

Is it a bug in Win7 or if there is any setting?

Emily
