BindingSource Get Current Row

Question

I cannot get current row value. How can i do?

bindingSource1.DataSource = LData; (LData is Generic List)

public DataRow currentRow
    {
        get
        {
            int position = this.BindingContext[bindingSource1].Position;
            if (position > -1)
            {
                return ((DataRowView)bindingSource1.Current).Row;
            }
            else
            {
                return null;
            }
        }
    }

I cannot get current row with :

    MessageBox.Show(currentRow["NAME"].ToString());

Getting Err: InvalidCastException, how can i do? Thanks.

You can't expect to have DataRow objects in bindingSource1.Current if you're setting DataSource to a List<T> instead of to a DataTable. In your case bindingSource1.Current will contain an instance of the generic type.

I suppose you're initializing LData like this:

LData = new List<T>();

The property should then look like this:

public T currentRow
{
    get
    {
        int position = this.BindingContext[bindingSource1].Position;
        if (position > -1)
        {
            return (T)bindingSource1.Current;
        }
        else
        {
            return null;
        }
    }
}

And you could read the value like this (assuming Name is a property of T):

MessageBox.Show(currentRow.Name);

Not tested of course, but something like this should work. Use the debugger in the following line to see what the contents of the Current property are actually like:

return (T)bindingSource1.Current;
