Store checked items from CheckComboBox in a string array

TAN WhoAMI

From the Extended WPF Toolkit, we have the CheckComboBox.
in a ItemsSelectionChanged event, I wish to store those checked items in a string array, is that possible?
I try below:

it does not work according to my needs:
say "abc" and "def" items were checked.
it gives me selectedCostCenter[0]=abc,def
what I need is:
selectedCostCenter[0]=abc
selectedCostCenter[1]=def

how do I modify the code for my needs?
thanks.

Code below:

    private void CheckComboBox_CostCenter_ItemSelectionChanged(object sender, Xceed.Wpf.Toolkit.Primitives.ItemSelectionChangedEventArgs e)
        {
            int SelectedItemsTotal = CheckComboBox_CostCenter.SelectedItems.Count;
            string[] selectedCostCenter = new string[SelectedItemsTotal];
           
            for (i = 0; i < SelectedItemsTotal; i++)
            {
                selectedCostCenter[i] = CheckComboBox_CostCenter.SelectedValue.ToString();
            }
         }

from my first discussion, I mentioned that I am using Extended WPF Toolkit. Normal window application does not allow us to have CheckComboBox, just the normal ComboBox.

I have no idea that you are using xceed WPF toolkit I gave solution for normal windows application

here is your code
private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            string[] CostCenterName = { "Analog", "Digital", "EMS", "INT1", "INT2", "INT3", "Photo", "QA", "SMT1", "SMT2", "US-PF", "US-PXS" };
            CheckComboBox_CostCenter.ItemsSource = CostCenterName.ToList();
            CheckComboBox_CostCenter.SelectedItem= "Analog";
        }

Error 1 'Xceed.Wpf.Toolkit.CheckComboBox' does not contain a definition for 'SetItemChecked' and no extension method 'SetItemChecked' accepting a first argument of type 'Xceed.Wpf.Toolkit.CheckComboBox' could be found (are you missing a using directive or an assembly reference?) C:\DriveD\TESTS4WORK\TestSystemUtilisation\MainWindow.xaml.cs 73 38 TestSystemUtilisation

no need to expose that method that's an info

I have modified your code use this
private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            string[] CostCenterName = { "Analog", "Digital", "EMS", "INT1", "INT2", "INT3", "Photo", "QA", "SMT1", "SMT2", "US-PF", "US-PXS" };
            CheckComboBox_CostCenter.ItemsSource = CostCenterName.ToList();
            //CheckComboBox_CostCenter.SelectedItems.Add("Analog");
CheckComboBox_CostCenter.SetItemChecked(0, true);
        }

hope it helps

what should be inside the function for
SetItemChecked(int index, bool isChecked)?
Biswa Pujarini Mohapatra12y ago
use this
CheckComboBox_CostCenter.SetItemChecked(0, true);

Exposed the SetItemChecked(int index, bool isChecked) method so that you can programmatically set an item as checked

            string[] CostCenterName = { "Analog", "Digital", "EMS", "INT1", "INT2", "INT3", "Photo", "QA", "SMT1", "SMT2", "US-PF", "US-PXS" };
            CheckComboBox_CostCenter.ItemsSource = CostCenterName.ToList();
            CheckComboBox_CostCenter.SelectedItems.Add("Analog");
        }

modify your code to

private void CheckComboBox_CostCenter_ItemSelectionChanged(object sender, Xceed.Wpf.Toolkit.Primitives.ItemSelectionChangedEventArgs e)
        {
            int SelectedItemsTotal = CheckComboBox_CostCenter.SelectedItems.Count;
            string[] selectedCostCenter = new string[SelectedItemsTotal];

            for (i = 0; i < SelectedItemsTotal; i++)
            {
                selectedCostCenter[i] = CheckComboBox_CostCenter.Items[i].ToString();
            }
         }
