I have been looking at all the other questions similar to this one and they just don't seem to help me with my particular problem.
I am using a Combobox with the following properties:
The purpose of the Combobox is simple, it is taking all the values of an unique column in a table, and present them as options. The column's name is "nim".
Upon initialization, the combobox loaded just fine:
The problem occurs after I changed the selected item to the 2nd one in the list, and tried changing it again:
When I tried selecting System.Data.DataRowView, this error appeared:
I have been playing around with the code to no avails. I didn't write any code concerning the combobox. I just assign the DataSource, DisplayMember, and ValueMember from the properties window manually.
The only code concerning combobox is these:
private void comboNIM_SelectedIndexChanged(object sender, EventArgs e)
{
//selectedNIM = ((DataRowView)comboNIM.SelectedItem).Row["nim"] as String;
selectedNIM = comboNIM.SelectedValue.ToString();
}
Any help will be really appreciated! Thank you!
So..., I have found a solution for this particular problem.
I deleted the ComboBox, and then created a new one. Then I just assign the properties programmatically. cb.DisplayMember = 'nim'; cb.ValueMember = 'nim'; cb.DataSource = mahasiswaBindingSource;
Apparently, leaving the properties window unedited solved the problem!
