textbox event

Hello @Carlos there are two method for this

either using "onchange" event of java script or text changed event of textbox

private void  TextBox1_TextChanged(object sender, EventArgs e)

//Write Your Code here

Text box contain a textchanged event , you can use it

private void  TextBox1_TextChanged(object sender, EventArgs e)

//you can write here

You can use these concept :

1)

onkeypress="document.getElementById('Label1').innerHTML=this.value;" />

2)

You can set the AutoPostBack property to True just like this:

AutoPostBack="True"

Will going to work better if you put the textbox inside an updatepanel from AJAX =)

In your html code:

ontextchanged="TextBox1_TextChanged">

private void  TextBox1_TextChanged(object sender, EventArgs e)

//you can write here

if works kindly accept this solution

You can use 'onchange' event in javascript which is Client side event

or You can use 'OnTextChanged' event in C# which is Server side event
