Bind GridViewComboBoxColumn to Enum values

[Joel Palmer]

I have a simple 3 column GridView.  The 2nd column is defined as a GridViewComboBoxColumn.  I would like to bind an Enum list to that ComboBox.ItemsSource property.  How do I do this?

On a typical combobox, I could do the following:

 

 

 

cboValueType.ItemsSource = Enum.GetValues(ValueType);

Thanks for your help.

Hello,Joe Palmer


You should make the following modficiation in your code:

cboValueType.ItemsSource = Enum.GetValues(typeof(ValueType));

Hi,

You can also see our online sample. On the right there is an option to bind the combo column to enum.
There is source code available there as well.

Yes, you are correct from standpoint of syntax in binding it to a typical combobox.  I typed it in from memory so I got it wrong.

However, you failed to answer the question.  The question is about how I populate a GridViewComboBoxColumn with these values from an Enum.

Thanks for your help,
Joel

Hello Joel Palmer,

The GridViewComboBoxColumn has its own ItemsSource property which is transfered to the comboboxes.  As demonstrated in the sample I pointed out below.

Okay.  I got this to work from the example.  Evidentially, I need to turn the enum values into a list.  Thanks for your help.

 

 

List<SqlCalculator.Library.ValueType> list =
    new List<SqlCalculator.Library.ValueType>();
foreach (SqlCalculator.Library.ValueType item in
    Enum.GetValues(typeof(SqlCalculator.Library.ValueType)))
{
    list.Add(item);
}
valueTypeColumn.ItemsSource = list;

I ran across you post while looking for something completely different. The documentation for ItemSource says that it is looking for an IEnumerable. Therefor your initial code example should have worked. The fact that it needed a List<T> instead indicates that it is actually looking for List<T>, IList<T>, or perhaps even IEnumerable<T>. Here is a shorter path.

valueTypeColumn.ItemsSource = Enum.GetValues(typeof(SqlCalculator.Library.ValueType)).OfType<SqlCalculator.Library.ValueType>();

This will work if ItemSource is looking for IEnumerable<T>. If it is actually looking for List<T> or IList<T> then you would use this.

valueTypeColumn.ItemsSource = Enum.GetValues(typeof(SqlCalculator.Library.ValueType)).OfType<SqlCalculator.Library.ValueType>().ToList();

Hope this helps you or someone else.
