Question

I have a ComboBox that is binded to a DataSet. I wanted to show the selected value whenever the ComboBox has a change in selection. I have the following code:

private void devCb1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    dv = new DataView(
        dt,
        "Device_ID = " + devCb1.SelectedIndex,
        "Data_ID ASC",
        DataViewRowState.CurrentRows);

    dataDg1.ItemsSource = dv;
    devCb1.DisplayMemberPath = "Content";
    MessageBox.Show(devCb1.SelectedValue.ToString());
}

But it only gives me

System.Data.DataRowView

I have already set the DisplayMemberPath, but it still not showing me the selected item’s content. What is wrong?

[EDITED]
I also tries the following

devCb1.SelectedValuePath = "Content";
MessageBox.Show(devCb1.SelectedValue.ToString());

But it also still gives me

System.Data.DataRowView

Doesn’t work either..

Answer 1

DataRowView has no content from what i can see. Your SelectedValuePath should point to Row i think (or if the current path correctly points to the Content of the ComboBoxItem you just need to cast at that point), and you’d still need to cast the SelectedValue being a row, to that class and from there you can get some of its content.

Set breakpoints, use the debugger, look at the data in your objects.
