Hi, could anyone give me example on how to maintain TabControl in ASP.Net?
Here's the problem :
- I have TabControl with many of Tabs
- Each of Tab contain various kins of object, i.e DataGrid.
- Each of DataGrid containing data from database with request query comes from textBox (say it txtCari).
- When I click SEARCH button,the value on txtCari become parameter for querying database.
- The reslt keept in DataGRid on each tab (each datagrid contain difeerent data) 
- But guess what?. It's need more than 6 seconds to load..
Can anyone give me the way how to makeitfaster?'
With xample please..

Hi,
Few tips to maintain the tabcontrol performance:
1.Do not drag drop many objects on to each tab.Instead used the user control and gives instances on each tab.
2.Check if you are loading data in all tabs each time a tab is clicked.(Page Posting back?).
3.Which tab control are you using ? asp.net or ajax? (put the tab control in ajax update panel to reduce the post backs)
Hope this helps to figure out where it is taking more time to load.

you can do that by using session or by sending data as paramter in the request
1-in first page
Session["Name"]=<any variable>;
Session["ID"]=<any variable>;
2- in other page
string x=Session["Name"].ToString();
other Soluation
1- in first page
Response.redirect("Default2.aspx?Name="+<any Variable>+"&id="+<anyVarible>);
2-in last Page
request.Get("Name");
request.Get("ID");

passing values in query string is a wrong practice as it will be exposed to other users .try delegates and events.you will find lots of article regarding thin in google

Hi,
another method is here to send data on page to another page though cookies.
Response.Cookies["UserName"].Value = "Erhan";
Response.Cookies["UserName"].Expires = DateTime.Now.AddDays(7);
string username = string.Empty;
if(Request.Cookies["UserName"] != null)
{
username = Server.HtmlEncode(Request.Cookies["UserName"].Value);
}

Hi,
As this is my first project, I really do not have much idea to debug this. I have a listview. I am writing code manually to populate listview. As the listview is very large, I have a search button where user enters a search string. I am trying to build a sql string from here and populate the listview. Everything works fine but when I click on next page, it does not include the search string. I think it is just populating the 2nd page without the search criteria. If I remove the data pager control, it works fine. I am not able to put proper code datapger_PagePropertiesChanging. I appreciate if someone can help me with this.
Here is my list view markup:
<div class="topcontent">
<asp:TextBox ID="txtSearch" runat="server" cssClass="txt"></asp:TextBox>
<cc1:TextBoxWatermarkExtender ID="tbwatermarkSearch" runat="server" TargetControlID="txtSearch" WatermarkText="Search Contractor..">

Is it possible,To remove session when user close his browser.
if yes , how?
|
|
|
|
|
|
It is for restoring Session not for deleting.
|
|
|
|
|
try this:
1. First create a page LogOut.aspx and in Page_Load event write this code:-
protected void Page_Load(object sender, EventArgs e)
{
Session.Abandon();
}
2. Then add following JavaScript code in your page or Master Page:-
<script type="text/javascript">
var clicked = false;
function CheckBrowser()
{
if (clicked == false)
{
}
else
{
clicked = false;
}
}
function bodyUnload()
{
if (clicked == false)
{
var request = GetRequest();
request.open ("GET", "AutoLogOut.aspx", true);
request.send();
}
}
function GetRequest()
{
var request = null;
if (window.XMLHttpRequest)
{
request = new XMLHttpRequest();
}
else
{
request = new ActiveXObject('MSXML2.XMLHTTP.3.0');
}
return request;
}
3. Add the following code in the body tag of master page.
<body onunload="bodyUnload();" Onclick="clicked=true;">
Finally the code in Master page like this:-
<script language="javascript" type="text/javascript">
var clicked = false;
function CheckBrowser() {
if (clicked == false) {
}
else {
clicked = false;
}
}
function bodyUnload() {
if (clicked == false)
{
var request = GetRequest();
request.open("GET", "LogOut.aspx", true);
request.send();
}
}
function GetRequest() {
var request = null;
if (window.XMLHttpRequest) {
request = new XMLHttpRequest();
}
else {
request = new ActiveXObject('MSXML2.XMLHTTP.3.0');
}
return request;
}
</script>
<body onunload="bodyUnload();" onclick="clicked=true;">
<form id="form1" runat="server">

You start by studying and doing the research necessary to give you the understanding so you will know where to start. In any case, there are numerous tutorials here and via Google that would help if you can be bothered to do your own work.

Not entirely sure what your problem is. You can certainly reference the jquery script file in your master page and, in fact, should do so. What error are you getting? Perhaps the path to the script is incorrect.
