Hi all,

I have three file upload controls and i am uploading 3 different images into all in pop up,

but when i clear the value of single fileupload control it clears the all other also,

so i need a code which clear a single control at a time,

i used Java Script code and c# code also but both behaving same as it clears the all controls

I have used this type of codes...

JavaScript

function ClearFileUpload1() {
var fil = document.getElementById("file1");
fil.select();
n = fil.createTextRange();
n.execCommand('delete');
fil.focus();
}

c#

C#

fileupload1.dispose();
fileupload1.Attributes.Clear();
fileupload1=new FileUpload();

Dude if you are going to server side to clear your control then you are doing wrong as you know if you are going to server side the whole page gets refresh so you have to do it using client side.

i got the solution for this problem

i m using now java script code
<script type="text/javascript">
function fnClearFileSelection(objFileUpload) {
objFileUpload.value = "";
objFileUpload.focus();
return false;
}
</script>

and the file upload is looking like this

<asp:FileUpload ID="fuPhoto" runat="server" ClientIDMode="Static"/>

and the Clear button looks like this

<asp:LinkButton ID="lnkClear" runat="Server" OnClientClick="return fnClearFileSelection(FuPhoto);"></asp:LinkButton>
