I think, you have enabled AutoPostback property. As you populated the DropDownList using AJAX, it difficult to maintain the ViewState after the Page postbacks.

assume your file upload control is FileUpload1

if (FileUpload1.HasFile)
    string fileExtension = System.IO.Path.GetExtension(FileUpload1.PostedFile.FileName)

Hope it helps

Hi Guffa , Navaneeth,
I posted this query earlier.But not getting , how to overcome the problem .

i have a java script funciton and a button server control in aspx page, which i am invoking at the form closing.Now the problem is , the same function is executing on button click as well as on the form closing button.

i was told by Guffa in this link and in this link
by setting the variable in onclick of the button, and check the value of the variable in the abc function.

My question is how i should declare the global variable , and how i should check it's value in the funciton

Hi Guffa , Navaneeth,

Please don't address the question to specific member(s). This might prevent others replying to your pos. As Guffa said in his post, you can declare a variable inside a script and outside a function. This will be treated as public variable. See the example below

<script language='JavaScript'>
<!--
var Submitted = false;
function window_onbeforeunload(e) { //This will be your unload function attached in body
	if (!Submitted) {
		    return(confirm("Are you sure to exit"));
        }
}
</script>

When any button is clicked, make this Submitted=true, which will avoid displaying the message.

Hope it helps

When you are writing make Submitted=true, which will stop the message from appearing. This value we are checking in the unload function, and message is displayed when this is false. So make it true, and message won't be displayed.

Strange

, why do you want this without file upload control ? ASP.NET won't get permission to access any files from the client system. So there is no other way. In worst case you can write an activex control and do it, But I am not sure on this.

Write a windows application that opens this file and send it as binary to a webservice, which stores the file on server. ASP.NET can't do what you are expecting.

Hi All,

I am adding conrols at runtime something like this:

//Label For Showing Symbol Text
Label lblSymbol = new Label();
lblSymbol.ID = "lblSymbol";
lblSymbol.Text = "Symbol";
lblSymbol.CssClass = "text";
tab1.Controls.Add(lblSymbol);

Panel PopupMenu = new Panel();
PopupMenu.ID = "newPanel";

//Div Tag
HtmlGenericControl watch = new HtmlGenericControl();
watch.Style.Value = "background-color:#FBFBFB ;border:1px solid Blue;width:40%";

StringBuilder strPOPUPCompanyMenu = new StringBuilder("");
strPOPUPCompanyMenu.Append("<table width='700px' border='1' cellpadding='0' cellspacing='0'>");
strPOPUPCompanyMenu.Append("<tr><td> </td><td class='text' width='500px' align='left'>Country</td>");
strPOPUPCompanyMenu.Append("<td align='left' width='250px'>");

//CascadingDropDown For Country
AjaxControlToolkit.CascadingDropDown CascadingDropDown10 = new AjaxControlToolkit.CascadingDropDown();
CascadingDropDown10.ID = "CascadingDropDown10";
CascadingDropDown10.TargetControlID = "ddlcountry";
CascadingDropDown10.Category = "Country";
CascadingDropDown10.PromptText = "Select a Country";
CascadingDropDown10.ServicePath = "AutoComplete_WatchList.asmx";
CascadingDropDown10.ServiceMethod = "GetCountry";

watch.Controls.Add(CascadingDropDown10);

//DropDownList For Country
DropDownList ddlcountry = new DropDownList();
ddlcountry.ID = "ddlcountry";
ddlcountry.CssClass = "text";
ddlcountry.Width = 250;
watch.Controls.Add(ddlcountry);

strPOPUPCompanyMenu.Append("</td><td> </td></tr>");
strPOPUPCompanyMenu.Append("<tr><td> </td><td align='left' class='text'>Sector</td><td> </td></tr></table>");

watch.InnerHtml = strPOPUPCompanyMenu.ToString();

//Add div Tag to Panel
PopupMenu.Controls.Add(watch);

//PopupControlExtender For Showing Company Panel
AjaxControlToolkit.PopupControlExtender PopupControlExtender14 = new AjaxControlToolkit.PopupControlExtender();
PopupControlExtender14.ID = "PopupControlExtender14";
PopupControlExtender14.TargetControlID = "lblSymbol";
PopupControlExtender14.PopupControlID = "newPanel";
