Comboboxcolumn at design time
May 16 2012 12:08 PM
I have set up a combobox column in a datagridview at runtime, it worked well (I could change or remove rows without any problem )but when I click at "+" button (Add) I get an error: "
datagridviewcombocell is not a valid value"
.
Then I tried to set up the same column at design time, all the properties used previously in the code were entered in the Properties pane,
I wonder how to use datasource for this column, since it is related to a derived entity.
With code it is used like this:
DataSource = Entities.Customers.Execute(MergeOption.AppendOnly)
May be is there a similar instruction to be used in Form load event?
NorthwindEntities nw;
private void Form1_Load(object sender, EventArgs e)
{
nw = new NorthwindEntities();
bindingSource1.DataSource = nw.Orders;
datagridview1.columns["ComboCol"] ......... .dataSource = nw.Customers.Execute(MergeOption.AppendOnly) ???
}
Thanks in advance.
