sorry, this code (<pre><pre lang="cs">) is not related of my code and I do not know how can I am editing my qustion
How can I upload my code?

Question editing is currently broken: the site owners have been notified, and will fix it as soon as they can - all you actually need to do when editing works is disable the "Ignore HTML..." option at the bottom. That will remove the pre tags and format your code better!

Here is how: uncheck "Ignore HTML", select radio button "allow HTML", replace angular brackets with HTML entities < >, escape everything else to be escaped.

protected void Page_Load(object sender, EventArgs e)
{

int CheckedCount = 0;
int tripNum = -1;
int BusNumber = 0;
string MyDate = "";
string MyTime = "";
foreach (GridViewRow R in GridView1.Rows)
{
CheckBox C = R.FindControl("CheckBox1") as CheckBox;
if (C != null)
{
if (C.Checked)
{
CheckedCount++;
tripNum = int.Parse(R.Cells[1].Text);
BusNumber = int.Parse(R.Cells[6].Text);
MyDate = R.Cells[4].Text;
MyTime = R.Cells[5].Text;
if (CheckedCount > 1)
{
Console.Write("Only one trip can be selected.", Response);
return;
}
}

When you say "it doesn't work", what do you mean? What is it doing that it shouldn't, or not doing that it should? Is there an error message?

dedoooo 10-Apr-11 10:02am

dedoooo 10-Apr-11 7:52am

The best place would be in the browser - something that may be simplified using jQuery.
jQuery gridview plugins[^]

Web applications split their execution/logic between browser (like FireFox or IE) and web server (like IIS).

To make anything happen server side the page has to perform some sort of communication with the server (like a postback, or calling a web service). So something (like a button) in the browser has to trigger that action.

Update
Work your way through:
http://msdn.microsoft.com/en-us/library/ms229601.aspx[^]
Then go through:
http://www.asp.net/web-forms[^]

This provides a thorough grounding on the basics of .Net development and asp.net.
