How to use the selectedITem or SelectedValue when selecting an item from a combobox?

[Frans vd Heuvel]

I have the following problem

How do you select an item from a combobox when this combobox receives data from a SQL database.

private void cmbMDCTestRequirements_SelectedValueChanged(object sender, EventArgs e)

Object selectedRequirement = cmbMDCTestRequirements.selectedItem;

Now this Object should be changed into an integer.

How should this be done ?

The cmbMDCTestRequi rements firs tis filled with data uysing the following code:

        private void FillDataInApplicationRequirementComboBox()
        {
            cmbMDCTestRequirements.DataSource = null;
            ApplicationSettings appSettings = new ApplicationSettings();
            dataset = appSettings.getApplicationRequirements();
            dsView = dataset.DefaultViewManager;
            cmbMDCTestRequirements.ValueMember = "ApplicationRequirements.Id";
            cmbMDCTestRequirements.DisplayMember = "ApplicationRequirements.RequirementDescription";
            cmbMDCTestRequirements.DataSource = dsView;

            totalCustomerRequirements = cmbMDCTestRequirements.Items.Count;
            txtTotalCustomerRequirements.Text = totalCustomerRequirements.ToString();
        }

Can you use SelectedIndex, perhaps?

Hi Gary, thanks for you answer, but no i don't like to use the SelectedIndex, because it gives the position in the combobox and not in the table of the database. but in the meantime i already have found the answer.

The answer is using the

DataRowView selectedRequirementItem = cmbMDCTestRequirements.SelectedItem as DataRowView;
if (selectedRequirementItem != null)
  {
     SelectedValue = selectedRequirementItem.Row.ItemArray[0].ToString();
  }

Now you really select the Id of a record of the database.

Thanks for your quick answer
