Assigning an object to a DataGridViewColumn.HeaderCell

Question

Hi Guys,

These is really confusing me.
I need to store a DateTime object to the column header of a DataGridView so I can refer to the object later.

Look at this code.

C#

DataGridViewColumn s = new DataGridViewColumn()

s.HeaderCell.Value = new DateTime.Now;

I am expecting the column header caption to have the value of the ToString() method of the date time object but instead its blank.

Now if I set s.HeaderText with a string value. It overwrites the object I assigned to HeaderCell to the string value.

Any idea where I went wrong?

Does that code compile?

I do think you cannot assign a DateTime object to a HeaderCell object.
What you can do is to assign the DateTime value to the HeaderCell value like this

C#

s.HeaderCell.Value = DateTime.Now.ToString();

If you want to retrieve the information you can use

C#

DateTime headerTime = DateTime.Parse(s.HeaderCell.Value);

hi, thanks for the reply and for editing the code. yes sorry it is HeaderCell.Value.. It accepts an object so it does compile and properly store the DateTime object. But it does not display it as caption. where as any other function that accepts an object automatically takes the ToString() returned value.. or maybe I'm approaching it the wrong way?

If I do it as you suggested then the value will be a string and not a datetime object. i need to store a datetime object cause later in the code i need to be able to get the object it holds.

As far as I can determine this is not possible.

But as I suggested you can parse back the date when you need to use the DateTime object.
