how can i used the web cache in dropdown box..i have 2 dropdownbox, dropdown1 w/ 5 list item. (autopostback=true)<asp:listitem>1<asp:listitem>2</asp:listitem>etc.in dropdown2, value will be depending on the item that will be selected on dropdwn1.sample;if i select in dropdown1 the "1", it will query all records with no. "1" then it will be post in dropdown2..and vice versa when i select the "2", my problem is when i select again the "1", it will query again the records in the dbase, and it really takes a long time to load the page again...how can i use the cache to past the of records with "1" in the cache, and then use it again when i need..it will a lot easier to load the page cause the data is already in the memory rather than getting it from database again and againthnx

here's my code://page name: mypage.aspxif(!IsPostBack){ //my select query===// if(d.GetCompanyNameLookup(ref dsCompanyName, ref strErrorDescription)) { cboAltCompany.DataSource = dsCompanyName.Tables[0]; thiscboAltCompany.DataTextField="INSTITUTE"; cboAltCompany.DataBind(); } //end//}//code when i submit//private void ImageButton2_Click(object sender, System.Web.UI.ImageClickEventArgs e) { if(objResume.AddEducation(lngResumeId, strDegree, strInstitute)) { Response.Redirect("mypage.aspx"); } }//my problem is when the page redirect, even if i used the ispostback, it also takes too long to load againor even if i had another dropdown with autopostback value="true" it is still reading my query that is why it takes time to load the page//is ASP.NET Caching capable for storing multiple records like all the value in the dropdown
