How to change Column Width of GridView programically - asp.net

Question

I have GridView that is filled programically using List of Object. I can't access to Columns in GridView. I like to put Width of Columns programically?Here is the code how I fill the GridView
DataClassesDataContext dContext = new DataClassesDataContext();
var userId = (Guid)(Membership.GetUser(Membership.GetUser().UserName, false).ProviderUserKey);
var tekovenKorisnikQuery = from d in dContext.pregledIshranas
where d.UserId == userId
select new {d.datum, d.kilogrami, d.visina, d.BMI, d.kalorii};
List<PregledIshranaFormatirano> listaFormatirana = new List<PregledIshranaFormatirano>();
foreach (var d in tekovenKorisnikQuery)
{
listaFormatirana.Add(new PregledIshranaFormatirano(string.Format("{0:dd-MM-yyyy}", d.datum), d.kilogrami.ToString(), d.visina.ToString(), string.Format("{0:N2}", d.BMI), d.kalorii.ToString()));
}
gvTekovenKorisnik.DataSource = listaFormatirana;
gvTekovenKorisnik.DataBind();
I use this event handler to change header
protected void gvTekovenKorisnik_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[0].Width = new Unit("200px");
e.Row.Cells[0].Text = "Датум";
e.Row.Cells[1].Width = new Unit("200px");
e.Row.Cells[1].Text = "Килограми";
e.Row.Cells[2].Width = new Unit("200px");
e.Row.Cells[2].Text = "Висина";
e.Row.Cells[3].Width = new Unit("200px");
e.Row.Cells[3].Text = "BMI индекс";
e.Row.Cells[4].Width = new Unit("200px");
e.Row.Cells[4].Text = "Калории";
}
In this way the width isn't changed and I can't access to gridView columns.
Could somebody help me?

Answer 1

You can change column widths right after GridView DataBind() method call.
For example: gvTekovenKorisnik.Columns[0].Width = %yourvalue%;
