'this.get_element().style' is null or not an object

It seems that you are trying to access the style before the element is initialized.
Can you debug by putting some alert in Javascript?
Do not know if this helps you much.

This is a Javascript error, where the element returns null.

I think if you set the autopostback of the Dropdownlist to false, the problem will be cured.
Or you can paste your designer code here to help you. Rose | [Rose]

I am not sure what you exactly mean by "sending SQL Query to a my local machine".
But in general ADO.NET provides all the features using which websites generally interact with SQL Server.
You can take a look into this[^] (still I am sure you are not looking for this simple thing Smile | :)

).
Anyway,let me know if you need something more.

Hello all,

I am dynamically creating DropDownList in my application.
While running application, when i select some value in DropDownList it is showing fine, but if i click some other button then DropDownList is always showing its first item.
I heard this happens because of PostBack.
I tried by setting AutoPostBack property to both true and false, but still same problem occuring both time.
Can anyone help me?

Thanks,
Nagendra.

Check that you are not rebinding the dropdownlist when the button click causes the postback.

only two letters away from being an asset

When did you create those Dynamic control. You have to create the dynamic control before page_load(), other wise that control will not be able to maintain viewstate and Postback datra, cause LoadViewState() and LoadPostbackData() called juts before page_load().

IF you created control before page_load,

Try to do this in

Page_Load()

if( ! Page.IsPostBack)

   {

      // Bind Data With Dropdownlist
   }

problems with variables

Hi,

I have some problem with using variables, I am making a form in C#?asp.net .

Now in my web application form I am having two controls on web page (dropdown, button); depending on the selection in the dropdown I have changed some value in a integer variable.

PROBLEM: the variable retains this value until the event ends.

after that I am using this value to do some processing; it is here that I find that the int value has changed back to 0(its default value). How can I prevent this as I need the value of the int?

I have tried my code both by declaring the int variable as global to that form and also by declaring it inside that particular event.

can someone please help me?

thank You
