From codebehind use search.Attributes.Add("onblur", "javascript:CheckMyConditions(this);"); where CheckMyConditions is your javascript function which checks the values. :rose:

You may want to consider using JQuery[^]. It provides a nice easy to use framework for what you are doing and more.

Hey, I think this might help you. http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=322157[^] This seems to be a bug in Visual Studio 2008 for 64Bit machines. Lets try out the workarounds.. If you can fix it.

Yes of course. Just define a function in your JS file, add that using script tag and call its function. Say you write like this :

function selectValue(obj)
{
alert(obj.value);
}

If you write txtbox.Attributes.Add("onblur", "javascript:selectValue(this);"); It will eventually produce an alert message with the value you provided in the textbox. Other than that, if you want to call like this : window.onload=initAll; The function declaration of initAll should be before the actual call. Otherwise undefined handler will be assigned to the event. :) Hope this helped you. :thumbsup:
