Hi Alexander
I use this senario for create editable RadComboBoxEditor. But I need to inheritance from two class !
please see this code :
01.namespace RadGridViewComboEditorCS
02.{
03.
04. public class MyComboBoxEditor : RadDropDownListEditor
05. {
06. protected override RadElement CreateEditorElement()
07. {
08. return new MyComboBoxEditorElement();
09. }
10. }
11. public class MyComboBoxEditorElement : RadDropDownListEditorElement
12. {
13.
14. protected override void ProcessKeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
15. {
16. if ( e.KeyCode == Keys.Enter || e.KeyCode==Keys.Tab)
17. {
18. MessageBox.Show("yes");
19. BindingList<string> stringsDataSource = (BindingList<string>)this.DataSource;
20. string currentText = this.Text;
21.
22. if (!ExistsInDataSource(currentText, stringsDataSource))
23. {
24. stringsDataSource.Add(this.Text);
25. this.SelectedIndex = this.Items.Count - 1;
26. return;
27. }
28. }
29. base.ProcessKeyDown(sender, e);
30. }
31.
32. private bool ExistsInDataSource(string currentText, BindingList<string> dataSource)
33. {
34. for (int i = 0; i < dataSource.Count; i++)
35. {
36. if (currentText == dataSource[i])
37. {
38. return true;
39. }
40. }
41.
42. return false;
43. }
44. }
45.}
in your code
1.public class CustomGridBehavior : BaseGridBehavior
so how can i inheritance from two class ( BaseGridBehavior and RadDropDownListEditorElement ) ?
BaseGridBehavior : for keys.KeyCode == Keys.Tab
RadDropDownListEditorElement for create editable RadComboBoxEditor
Thanks Telerik .
