Hi guys,

I have the following code

                cmbColHeader1.Items.Clear();
                cmbColHeader1.ItemsSource = lst; 

Open in new window


However I have 25 comboboxes, all with the same name and just a different number on the end, there must be a better way than having to do...

                cmbColHeader2.Items.Clear();
                cmbColHeader2.ItemsSource = lst;

                cmbColHeader3.Items.Clear();
                cmbColHeader3.ItemsSource = lst;

                cmbColHeader4.Items.Clear();
                cmbColHeader4.ItemsSource = lst;

etc etc.

Thanks,
Dean

Loop all combo boxes easily with below code.

foreach (var comboBox in myForm.Controls.OfType<ComboBox>())
{

  if(comboBox.Name.IndexOf("cmbColHeader") != -1)

   {
    comboBox.Items.Clear();
    comboBox.ItemsSource = lst; 

  }
}

Open in new window

Looks good but this is a WPF project so myForm throws an error?

int Newcount = VisualTreeHelper.GetChildrenCount(gpbColumnHeaders_grid);
                System.Windows.MessageBox.Show(Newcount.ToString());
                for (int i = 0; i < Newcount; i++)
                {
                    Visual childVisual = (Visual)VisualTreeHelper.GetChild(gpbColumnHeaders_grid, i);
                    if (childVisual is System.Windows.Controls.ComboBox)
                    {
                        
                    }
                }

Open in new window


The message box in the above returns the correct number of combo boxes, how do I assign the same data sources to them? I cannot get ..

System.Windows.Controls.ComboBox.ItemsSource

It only allows me to have ItemSourceProperty?

Thanks,
Dean
