}

Literal Control

protected void Button1_Click(object sender, EventArgs e)
{
Literal1.Text = "Welcome to ASP.NET 2.0";
}

Label Control

Source Code is:

protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text = "Label Text changed";
Label1.BorderStyle = BorderStyle.Dotted;
Label1.BackColor = System.Drawing.Color.Aqua;
}
protected void Button2_Click(object sender, EventArgs e)
{
Label1.Visible =!(Label1.Visible);
}

HiddenField Control

Html Code is:

asp:HiddenField ID="HiddenField1" runat="Server" Value="Welcome to ASP.NET 2.0"
Visible="False"

Source Code is:


protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text = HiddenField1.Value;
}

File Upload Control

Source Code:

protected void Button1_Click(object sender, EventArgs e)
{
if( FileUpload1.HasFile)
{

FileUpload1.SaveAs("C:/projects/" + FileUpload1.FileName);
Label2.Text = "File Uploaded";
}
else
Label2.Text = "No uploaded file";

}

Databound Schedule controls for Project Management

These are two free controls, ScheduleCalendar and ScheduleGeneral, designed to show scheduled events in the form of a table. They are simple versions of the so-called Gantt chart. They don't have advanced features such as dependencies and milestones, but on the other hand, they use templated databinding, so it's up to you, the developer, what you want to show.

The controls can be used for a broad variety of applications: time tables, resource usage planners, calendars, event schedulers, activities, reservations, sequences, project management, etc... See the demos for some examples.

Sending Mails using AOSMTPLib

Firstly Install ansmptp.exe :

Source Code:

using AOSMTPLib;

AOSMTPLib.MailClass oSmtp = new AOSMTPLib.MailClass();


oSmtp.FromAddr = "sunichand2000@yahoo.co.in";
oSmtp.AddRecipient("Support Team", "sunichand2000@gmail.com", 0);

oSmtp.Subject = "Test";
oSmtp.BodyText = "Hello, this is a test....";

if (oSmtp.SendMail() == 0)
{
Response.Write("Message delivered!");
}
else
{
Response.Write(oSmtp.GetLastErrDescription());
}

Conversion of datetime to 24 hour format

String militaryTimeFormat = "HH:mm";

String input = DateTime.Now.ToString(militaryTimeFormat);

DateTime time = DateTime.ParseExact(input, militaryTimeFormat, null);

string militaryTime = "06/12/2008 20:30";

IFormatProvider culture = new System.Globalization.CultureInfo("en-US", true);
DateTime militaryDate =DateTime.Parse(militaryTime, culture, System.Globalization.DateTimeStyles.NoCurrentDateDefault);


string g=DateTime.Now.ToString("dd/MM/yyyy HH:mm");
string h = DateTime.Now.ToString("HH:mm");

Dynamic Creation of Controls

Output:












Firstly add a panel control ,a textbox and a button to design page .when we enter a number in textbox at run time ,the same number controls are created at runtime.


Source Code:

protected void btninsert_Click(object sender, EventArgs e)
{
int count =Convert.ToInt32(TextBox1.Text);
Panel1.Controls.Clear();
Table tb = new Table();
tb.GridLines = GridLines.Both;
for (int i = 0; i < count; i++)
{

TableCell c1 = new TableCell();
TableRow rw = new TableRow();
TextBox tx = new TextBox();
c1.Controls.Add(tx);
rw.Cells.Add(c1);
tb.Rows.Add(rw);
}
Panel1.Controls.Add(tb);
}
