[jojoba2011]

Hi, i wanna to call the bellow function while the Textbox1 got focus (when user click on Textbox1 OR when user press tab and textbox1 got focus):

`Untitled Page            function Open() {             var Return;             var myObject = new Object();             myObject.TextBox1 = document.getElementById("txtFirstName").value;             if (window.showModalDialog) {                 Return = window.showModalDialog("childform.aspx", myObject, "dialogWidth:670px;dialogHeight:600px;")                 document.getElementById("txtFirstName").value = Return.firstname;                 }         }`

Write this in your code behind file:

myTextBox.Attributes.Add("onfocus","javascript: Open();");

This will add the onfocus client side event to your textbox.

In order to call the JavaScript function, Just use the Following: protected void Page_Load(object sender, EventArgs e) { TextBox1.Attributes.Add("onfocus", "Open()"); } This will bind the "onfocus" event of TextBox1 to the javascript function "Open()"

But unlike others i believe you should handle it from your client and not ASP.net. You should implement it as follow:

document.getElementById("<%= TextBox1.ClientID %>").onfocus=function(){Open();}
