You can't check the file size using Javascript, you can't access the file system of the client computer.
Experience is the sum of all the mistakes you have done.

I can something else. I can onchange event of the FileUpload object display the selected image on image object (all of this in client side) and then check the size of the object. The problem is that I am not succeed to display the picture. What is the prblem?
See my code:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<script type="text/javascript">
function upload() {
var oThumbnail = document.getElementById("imgThumbnail");
filename = document.getElementById('myfile').value;
oThumbnail.src = "file:///" + escape(filename).replace(/%5C/gi,'/').replace(/%3A/gi,':');
oThumbnail = null;
}
function getSize(oImg)
{
if (oImg.fileSize >-1) {
document.getElementById('sizespan').innerHTML = oImg.fileSize;
}
}
</script>
</head>
<body>
<form id="form1" runat="server">
File: <input id="myfile" name="datafile" type="file" size="40" onchange="upload();" />
</form>
<div id="sizespan"></div>
<div id="thumbnail">
<img id="imgThumbnail" src="" alt="place holder" width="50" height="50" onload="getSize(this);"/>
</div>
</body>
</html>
What 's wrong?
Thanks

You'll need to use something like this[^] or this[^]. Both work on the server side.

In order to ajaxify the website ,I firstly , invoked a master page, then an another page and selected the same master page for that.Now in the page in inserted the table control and in the first row , I drag dropped the Script Manager control.then in souce file, it was showing the following error.
Element Script Manager is not a Known Element.This can occur if there is a compilation error in the website
There is no problem in the script manager tag , if i don;t select the master page for any web page.
Any idea?

Hello Friends,
I want to display image(s) in the datagrid. I'm storing images name in a field and a folder name into another field
c:\Images\1.jpg
for example "Images" is the folder name and 1.jpg is the image name .............
And also i've done it if i store Foldername with Filename in the same field. But i don't want to use this method because of some probs.
So plz suggest me the way .................

What problems are you having storing the folder name and file name in the same field?
Are the \ characters causing the problems?
If so you can escape the \ character like so:
string a = @"c:\Images\1.jpg";<br />
string a = "c:\\Images\\1.jpg";
Storing the separate path values in separate fields will cause you more problems if you create nested folders.

You will need to keep the DataTable in session and when the user selects a value from the dropdown list do a postback.
Then in the ItemDataBound event you can get the selected value for a particular row index and compare it to the value in the DataTable at the same row index.
If they are equal you can set the selected state of the checkbox to true.

Hi Bright thanks for ur reply:
see i did like the following code,but its comparing with the datatable last value only,
whats wrong in my code?
For Each gvr1 As DataGridItem In SubGRD.Items
Dim pno As Integer = Val(gvr1.Cells(0).Text)
Dim cb As CheckBox = CType(gvr1.FindControl("chk1"), CheckBox)
For Each dr As DataRow In dt.Rows
If (dr("pageno").Equals(pno)) Then
cb.Checked = True
Else
cb.Checked = False
End If
Next
Next
Help me
Thanks & Regards,

You should be comparing the selected value against the DataRow with the same RowIndex rather than checking against each DataRow. This is the reason you see it comparing against the last value only.

web.Config file or some external XML file ? If it is in web.config, you can fetch it using ConfigurationManager.AppSetting. If it is external XML file, use XMLTextReader/XMLDocument etc.

hi,
hw do i create a drop down menu using asp.net with VB? for example, i want a file, edit etc kind of tool bar / drop down menu.
does anyone have any sugeestions or example code for this and maybe the functionality of such features like how to open a file, cut copy and paste.
thanks

Buy a book on ASP.NET, you obviously have no idea how it works. You can do menus in javascript ( but not in VB, that runs on the server ), but you can't open files, cut, copy or paste within a web app.
