you need to use timespan function or you can also use
System.DateTime dtTodayNoon = new System.DateTime(2006, 9, 13, 12, 0, 0);
System.DateTime dtTodayMidnight = new System.DateTime(2006, 9, 13, 0, 0, 0);
System.TimeSpan diffResult = dtTodayNoon.Subtract(dtYestMidnight);

The OP was not asking for the difference between 2 datetimes, he asked for a datetime minus 2 days

Buy a basic ASP.NET book and read it. Learn to use intellisense to investigate methods on a class. Learn to use google, and the MSDN site in particular. Asking in the right forum ( this has nothing to do with ASP.NET )
The DateTime class has everything you need.

As counter-intuative as it might seem at first glance, it is totally appropriiate to supply a negative number to the AddDays[^] method on a DateTime.

I found the issue.
I had a folder named Membership. I changed the name of the folder and the inheritance of the code behind and now it works!

Hi all,
i am trying to get the text from a label that it is inside of a detailsview field. This field is in fact a template field, and inside its ItemTemplate there is the Label control (ID = "Label8") which Text property i want to read.
i tried the following without success (returns c = null):
System.Web.UI.Control c = dvCU.FindControl("Label8");
string s = ((System.Web.UI.WebControls.Label)c).Text;
can anyone help me?
Thanks in advance.

where is your code. In other words, which method is your code in.
you can not get the controls the way you are showing.
1. you need to access your details view control
2. then you need to access specific row in the control
3. then you need to do a find
protected void grdItemDetail_RowDataBound(object sender, GridViewRowEventArgs e)<br />
{<br />
Image img = (Image)e.Row.FindControl("Thumbnail");<br />
}

Hi Yusuf,
the code is located on a void arguments method, which i invoked somewhere inside the "father" gridview _SelectedIndexChanged() method :
public void BlahBla()
{
...
System.Web.UI.Control c = dvCU.FindControl("Label8");
string s = ((System.Web.UI.WebControls.Label)c).Text;
}
You are right, i think now the problem is that i need some argument that contains the detailsview control so i can access it in right way. So i went to the detailsview_DataBound() event, and did this:
protected void dvCU_DataBound(object sender, EventArgs e)
{
if (((DetailsView)sender).FindControl("lblAlcance") != null)
iAlcance.ImageUrl = "~/Recursos/Iconos/Alcance (scope)/" + ((System.Web.UI.WebControls.Label)((DetailsView)sender).FindControl("lblAlcance")).Text + ".png";
if (((DetailsView)sender).FindControl("lblNivel") != null)
iNivel.ImageUrl = "~/Recursos/Iconos/Nivel (level)/" + ((System.Web.UI.WebControls.Label)((DetailsView)sender).FindControl("lblNivel")).Text + ".png";
}
and... voila!! the thing worked as charm!!
Thanks a lot for your help.
Sorry if i explain not very good, i am very noob at asp and c#.
