I told you, based on the information you gave us, there's not much else I can say. And, you're not really using AJAX, you're using a Microsoft library which does AJAX for you. This probably limits your access to information that allows you to do debugging or to control the process.
You can set breakpoints in your code, and you can see what code is taking that long. We sure as hell can't tell you what code is taking that long, we've not even seen your code.

OK, so this is obviously test code. What happens if you set breakpoints in this code ? I'd assume the AJAX calls count as a postback, but it's worth checking.
If you set your breakpoint in index changed event, does it fire right away, or after the 5 minutes ? This is the sort of thing you need to be doing, in order to work out where the problem lies.

when i am selecting a data the ispostback event is working properly.But when it comes to selected index changed event the code
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
TextBox1.Text = DropDownList1.SelectedItem.Text;-> this much is working fine.
but when it comes to
} here it's taking time

OK - it seems to me then that you're hitting something to do with the framework itself. It does seem odd. I don't use the MS library myself, so I really don't know what could cause this. I will say that if you wrote your own AJAX code, you'd have a lot more control over what was happening.

How to find the primary key or foreign key of a table using adapter.
VanithaVasu
|
|
|
|
|
To find the primary key
call the DataAdapter.FillSchema method on any selectcommand. you will be able to get the primary key using DataSet.Table("Name").PrimaryKey
You can't use the same approach to find the foreign keys

Hi,
I have a following code
how to upload xml file to server.
// files upload function
function btn_send.onclick()
{
// create ADO-stream Object
var ado_stream = new ActiveXObject("ADODB.Stream");
// create XML document with default header and primary node
var xml_dom = new ActiveXObject("MSXML2.DOMDocument");
xml_dom.loadXML('<?xml version="1.0" ?> <root/>');
// specify namespaces datatypes
xml_dom.documentElement.setAttribute("xmlns:dt", "urn:schemas-microsoft-com:datatypes");
// create a new node and set binary content
var l_node1 = xml_dom.createElement("file1");
l_node1.dataType = "bin.base64";
// open stream object and read source file
ado_stream.Type = 1; // 1=adTypeBinary
ado_stream.Open();
ado_stream.LoadFromFile("c:\\tmp\\myfile.doc");
// store file content into XML node
l_node1.nodeTypedValue = ado_stream.Read(-1); // -1=adReadAll
ado_stream.Close();
xml_dom.documentElement.appendChild(l_node1);
// we can create more XML nodes for multiple file upload
// send XML documento to Web server
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
xmlhttp.open("POST","./default.aspx",false);
xmlhttp.send(xml_dom);
// show server message in message-area
div_message.innerHTML = xmlhttp.ResponseText;
}

you can use file upload control that is already provided
Thanks and Regards

The only way is to use Javascript on the client side. You can add an attribute to do that to the ASP.NET control in Page_Load for example.
Assuming you have a button btnSubmit, you would do something like:
if (!IsPostBack)
{
btnSubmit.Attributes.Add("onclick","return confirm('Submit report?');");
}
The first parameter of the Attributes.Add method is the clientside event, the second parameter is any Javascript code you would like to execute.

ooops, you're right. Popping up a message box is such a common question that I thought this is what the question was. Sorry my mistake

ASP.NET can't do anything on popping up a window. It can be done by client side scripting like Javascript. Try window.open("pagename").

No,i didn't get it yet. actually i would like to open calendar control in a pop-up window when user clicks a button.

Hi All...
i have one doubt that how can we control firing server side event based on returned value of client side function...
I am building one page which have one asp.net textbox, i have added one clientside event to it in pageload by:
TextBox1.Attributes.Add("onchange", "getClient();");
// i tried below one also, but no help
TextBox1.Attributes.Add("onchange", "return getClient();");
I am returning true or false based on some logic in client side function "getClient()". now my problem is that if getClient function is returning false, i want to stop server side TextChanged event from firing for the same textbox...
but in my case it's always firing server side textchnaged event...
how to achieve it? plz help me...

I'm no expert in this matter but I'm thinking if you check the source of the page and find out what is the event of the textbox that is causing the postback for the TextChanged server side event, maybe you can reassign this event to an empty string in Javascript. For example if you have a button, you would have something like that:
<input type="submit" name="ctl00$MainContent$btnLogin" value="Log In" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$MainContent$btnLogin", "", true, "", "", false, false))" id="ctl00_MainContent_btnLogin" .....
If you can find a way to reset the btnLogin call here: new WebForm_PostBackOptions("ctl00$MainContent$btnLogin", maybe you can prevent the server side event from calling the method assigned to it.
Sorry can't be of more help.

Thanks for reply sultan...
it was something new to me. but in my case if i will do it then server side will not be fired though my javascript function is returning true and my application is all set to the conditions when server side shpuld be fired. i think i am not wrong, but if i am wrong please let me know.
actually there is a way for this, if i use below for adding event to textbox:
<asp:textbox id="TextBox1" onchange="return getClient()" runat="server" autopostback="True" ontextchanged="TextBox1_TextChanged">
this works like if onchnage event bound jscript function (getClient in my case), is returning true then only server side textxhnaged will be fired. but for me it's not firing, i think because i am not following this approach nd adding event at page load (needed as asp.net textbox not having onchange)so this approach is not working.
