pass "calendar.selectedvalue" in querystring from gridview

I wanted to pass "calendar1.Selecteddate" in a query string from gridview in one page to another gridview (I have written sqlquery in that gridview) in another page. As seen in the below code I tried passing it but this did not work. Can anyone tell me how to pass the selected date from calendar in query string

      <asp:HyperLinkField DataNavigateUrlFields="LocalIP" 
                DataNavigateUrlFormatString="DailyResults.aspx?
           Terms={0}&column=LocalIP&    
               startdate=Calendar1.SelectedDate.Date.Date.ToShortDateString()
                DataTextField="LocalIP" HeaderText="User" />

From stackoverflow

• In the example you've provided it would treat that calendar part of the string as a literal and pass the exact value you have typed. In order to obtain the data using you would need to do something similar to:

  <asp:HyperLinkField DataNavigateUrlFormatString="<%=GetSelectedDate()%>....
  

  where this is a method on the code behind class (or you could use a property) that creates the string you intend, including the {0} placeholder for the LocalIP bound data field.

• I am assuming the calendar selected value has not changed since the gridview was rendered.

  <asp:HyperLinkField DataNavigateUrlFields="LocalIP" 
       DataNavigateUrlFormatString='<%# "DailyResults.aspx?Terms={0}&column=LocalIP&startdate=" + Calendar1.SelectedDate.Date.Date.ToShortDateString() %> DataTextField="LocalIP" HeaderText="User" />
  

• HectorMac,

  Ur code did not work. Its giving me the following error:

  Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

  Parser Error Message: Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.HyperLinkField does not have a DataBinding event.

• One solution is to build your URL string in the code-behind, instead of building it in the markup.

  Override the RowDataBound method on the GridView and build the hyperlink programmatically:

  protected override gv1_RowDataBound(object sender, GridViewRowEventArgs e)
  {
    HyperLink hl = new Hyperlink();
    hl.NavigateUrl = string.Format("DailyResults.aspx?Terms={0}&column=LocalIP&startdate={1}", localIp, Calendar1.SelectedDate.Date.Date.ToShortDateString());
    .. set other hyperlink fields ..
    e.Row.Cells[1].Controls.Add(hl);
  }
  

  Hope that helps!
