Thanks for answer..so static variable will be maintained at server during subsequent page requests..right?

Thanks..But I tried something like this.. static int i; protected void Page_Load(object sender, EventArgs e){}protected void Button1_Click(object sender, EventArgs e) { i=i+1; TextBox1.Text=i.ToString(); } For each Button Click event, the value of "i" is incremented and displayed in the TextBox. I have clicked the button 5 times and the text box shows 5 in it. At this moment,when I opened another browse , copy - paste the same url and I tried to click the button, it shows "6" in it. Then why it working when i am opening the page in new browser window..My question is whether making it static will make it remember at server during subsequent page postbacks or not? Warm Regards, Rahul

Hi friends, If I am making my some member variable of a class as a static(say int i),then at each Page Postback i m able to manipulate(say increment) the previous value of i.My Question is whether by making member as a static are we making it to be remember by server during subsequent page requests..if so then how http is stateless.. Warm Regards, Rahul Agarwal

Thanks a lot Arun..u understood my question..and answered precisely..

Hi friends..plz go through this pseudo code I Included Requirid Namespaces Dataset ds;--------------------------------------1 //static Dataset ds;-----------------------------2 protected void page_load(parameters) { ds = function in Data acesss Layer which retrives records from database and returns dataset. populatedatagrid(); } void populatedatagrid() { if(mydropdownlist.selectedIndex=0) datagrid1.datasource=ds; else { datagrid1.Datasource= here I performed filtering action using Row Filter Property and selected Index Value } } void mydropdownlist_selectedIndexchanged(parameters) { populatedatagrid(); } I am designing a web page where by default all records will displayed.but by selecting from dropdownlist I can filter the records.Later I thought its not right to perform the fuctionalities of the page_load event at each postback(unnecessry making connection to the database)..so i used Page.Ispostback to avoid that..so first time it worked fine but when i selected from dropdwn list it throws an error "object reference not set to an instance of object".. reason for above error i understood(because in page load event i am returning dataset which does not happened at page post back)..so one of my friend commented the line no-1 and uncommented the line no-2 in above code..thus made dataset static..and it works What I am not understanding is why making the dataset static solved the task..though HTTP is static?Is making dataset ststic makes the records to be saved at server?

Warm Regards, Rahul

Tahnks a lot for clearing my doubt..
