Changing properties of textbox in visual studio 2010

Changing properties of textbox in visual studio 2010

To change the properties of the textbox at run time we need a textbox whose properties we will be changed 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.

Label1           

            ID: lbl_Name

            Backcolor: Aqua

            BorderColor: #660066

BorderStyle: Double

BorderWidth: 5px

Font:

            Bold: True

            Italic: True

            Name: Book Antiqua

            ForeColor: Red

            Text: Name

ToolTip: Enter Your First Name

Textbox1

ID: txt_name

Accesskey: n

Button1

            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.

And in this window you can write the following code.

protected void btn_click_Click(object sender, EventArgs e)

        {

            txt_name.TextMode = TextBoxMode.MultiLine;

            txt_name.Text="My name is Meetu ";

        }

This will change the mode of the textbox to multiline and the text as well.

The following code will be executed when the text of the textbox will be changed but here is a catch if you will not change the autopostback property of the textbox to true this event wont execute and the default value for autopostback is false as in most of the cases we do not prefer a textbox to call the code form the server side.

        protected void txt_name_TextChanged(object sender, EventArgs e)

        {

            lbl_Name.Text = "event called";

        }

Now you can run the program and check these properties and events and can try changing more properties.

Textbox Properties

Textbox Properties

 

In this article I will be talking about the few most commonly used properties of the textbox control. Some of the properties are similar as the label control which you can find here or on the mirror link

Rest of the properties I will deal in this article

 

Property              Purpose

ID                            to change the name of the control which we use in code file

AccessKey           the shortcut key used with the combination of alt to access the control at runtime

Columns              to set how many charters will be displayed in the textbox

Rows                     to set how many lines will be displayed in the textbox

Enabled                                true or false to set whether the control can be accessed by the user at runtime or not

MaxLenght         to define how many characters can be entered in the textbox if it is 0 that means no limit is set

ReadOnly            true or false to set that the value of control is not changed at runtime by the user

                                If true user can't change the value

TextMode           Single: user can enter value in one line

                                Multiline: user can use the enter key to insert new line and type in the new line

                                Password: acts like a password field the actual characters will not be displayed
