I need to dynamically create a GridView that contains a variable number of columns that must be bound to an underlying collection in an entity class.
These columns represent days from a specified Start Date to a specified End Date. For eg. if the user selects 01/09 and 04/09, 4 columns need to be added to the GridView.
My GridView is bound to an ObjectDataSourc e.
The ObjectDataSourc e is configured to an entity class, say, TimeSheet.
The TimeSheet entity class contains an int array, _days, which needs to be bound to the dynamically created columns in the GridView.
This is the code for the function that creates the additional GridView columns:
private void ModifyGrid()
{
int noColumnsRequir ed = DateDiffInDays( StartDate.DateV alue, EndDater.DateVa lue) + 1;
DateTime currentDate = StartDatePicker .DateValue;
for (int i = 0; (i < noColumnsRequir ed); i++)
{
// add a column to the gridview
BoundField dayField = new BoundField();
dayField.DataFi eld = "Day1"; // we need to bind to an underlying collection element!
dayField.Header Text = "Day" + i;
GridView1.Colum ns.Add(dayField );
}
}
(Day1 is an int property in the entity class which I have used to test)
My question is: How do I bind a GridView column to an underlying collection in an entity class?
