Hi,
I am trying to populate a combobox from 2 string arrays, the first array contains the name of the item and te second one contains the value of the item:
string[] RangeName;
string[] RangeValue;

RangeName = (new string[] { "Uni10Volts", "Uni5Volts", "Uni2Pt5Volts", "Uni2Volts"});
RangeValue = (new string[] { "100", "101", "102","103"});

so, when the user selects i.e Uni10Volts from the combobox, I want to be able to retrieve the value 100 when using the SelectedValue property. what do I need to add to the following code:
int i;
for (i = 0; i < RangeName.Length; i++)
   {
        this.cmbScanRange.Items.Add(RangeName[i]);  //This will add the array to the combobox

        // what do I need to add here
   }

It was really easy in vb with the DataFieldValue and DataFieldText but I don't have such an options.

does anyone know how to accomplish this task?

thanks

Are you talking about WinForms or ASP.NET?

WinForms ComboBox has DisplayMember and ValueMember.

WinForms ComboBox
I tried DisplayMember and ValueMember but I was getting always the last value added to the combobox

Try this:

DictionaryEntry[] items = {new DictionaryEntry("Uni10Volts", "100"), new DictionaryEntry("Uni5Volts", "101"), new DictionaryEntry("Uni2Pt5Volts", "102"), new DictionaryEntry("Uni2Volts", "103")};

this.cmbScanRange.DataSource = items;
this.cmbScanRange.DisplayMember = "Key";
this.cmbScanRange.ValueMember = "Value";
