get control id from the content page
-
hi, i have need a functionality like as soon we click the button at the moment that button will hide and after that the functionality should fire written in code behind along with that button.i am working as follows;
function check() { document.getElementById('Button1').style.visibility= "hidden"; return false; }code behind as follows:protected void Page_Load(object sender, EventArgs e) { Button1.Attributes.Add("onclick", "javascript:return check()"); } protected void Button1_Click(object sender, EventArgs e) { Response.Write("success"); }this not working properly. and i have to do this for a content page having this Button1 so the problem is the the getElementById is not working. Regards, Srinandan..When the HTML is written out to the Page, your button's ID in the HTML probably isn't "Button1". That means your javascript method will fail. To get around this, write the javascript into a String on the Server-Side and add it to the Page by using the RegisterClientScriptBlock method. When inserting the Button's ID, use MyButton.ClientID to get the correct id.

Regards, Srinandan..In order to ensure that controls have a unique id on the page, ASP.NET will rename your controls as it renders them. In order for you to retrieve the id of a server control on the client side, you will need to progratically reference the
ClientIDproperty of the button. Using theClientIDproperty, you could refactor your code into something like: Client Script:<script language="javascript" type="text/javascript">
function check(buttonId)
{
button = document.getElementById(buttonId);
if (button)
{
button.style.visibility = "hidden";
}
return false;
}
</script>
Server Code:
protected void Page_PreRender(object sender, EventArgs ea)
{
button1.Attributes.Add("onclick", String.Format("javascript:return

in the catch block you can make the button visible like the following line Button1.Visible = true;

I'm sorry, I must have misunderstood your post. If you'd like the server code to fire, simply change the javascript function to return
trueinstead.--Jesse "... the internet's just a big porn library with some useful articles stuck in." - Rob Rodi
