Changing Label Properties at run time

Changing Label Properties at run time

To change the properties of the label at run time we need a label whose properties we will change and an event on which we can see the changes that we have made are applied so to solve the purpose of an event I have taken a command button or button whose click event will work for as the triggering event.

A Design view is shown here.
There are three controls:
And following changes are made to their properties.

            ID: lbl_Name
            Backcolor: Aqua
            BorderColor: #660066
BorderStyle: Double
BorderWidth: 5px
            Bold: True
            Italic: True
            Name: Book Antiqua
            ForeColor: Red
            Text: Name
ToolTip: Enter Your First Name

ID: lbl_result
            ID : btn_click
Text: Click

Then you can either double click on the button in the Default.aspx page or you can double click on the combobox in the properties window under events in front of click event in order to generate the click event.
Once you will do that you will see the following window.

Add the following code to the event and run the project
Now the event will look like

protected void btn_click_Click(object sender, EventArgs e)
            //lbl_Name.Text = "Meetu Choudhary";
            lbl_Name.BackColor = System.Drawing.Color.Blue;
            lbl_Name.ForeColor = Color.Red;
            lbl_Name.Font.Bold = false;
            lbl_Name.Font.Italic = false;
            lbl_Name.Font.Underline = true;
            lbl_Name.BorderColor = Color.Black;
            lbl_Name.BorderStyle = BorderStyle.Solid;
            lbl_result.Text = lbl_Name.Text;

To use the following line
            lbl_Name.ForeColor = Color.Red;

You need to add
using System.Drawing;

In the using section.
Now you can run the project and when you will click the button at run time you will see the changes.
