Javascript call

[AB7771]

Hi Guys, i am a bit new to ASP .net web development. I have created a user control and placed some radio buttons, now i want to call a javascript function on the OnCheckedChanged event of the radio button. I googled but to no use. Also on my web page if i try to call a javascript it gives me error. Can anyone please tell me the correct way to call javascript in both the cases. Thanks in advance,

Thanks & Regards, Pramod "Everyone is a genius at least once a year"

Solution for OnCheckedChanged event of the radio button. check with ClientScript.RegisterClientScriptBlock e.g.[ some pseudo code]

public void ShowMessage(string input) {
string strScript = String.Empty;
strScript =@"<script language=javascript> ";
strScript = strScript + "alert('"+input+"')";
strScript = strScript + @"</script>";
RegisterClientScriptBlock("clientScript", strScript);
}

protected void rdButton_OnCheckedChanged(object sender, EventArgs e)
{
ShowMessage("Niladri Showed a way to solve the problem");
}

Check for the next part, add <pre><script language="javascript" type="text/javascript"></pre> If not you are making any mistake it is guarented to work. Vote please :)

OnCheckedChanged is a server side event and fires only when AutoPostBack is turned on. So hooking a JS function from here is pointless. I guess you want to call a JS function when someone clicks on the CheckBox, right? Use the Attributes[^] property to add a onClick attribute. Something like YourCheckBox.Attributes.Add("onClick","JsFunction();") Do this on the page load, so that your checkbox renders with this attribute and JsFunction() will get called when user clicks on the checkbox. :)
