It would be helpful if you show atleast some sample code. Thanks, Rajdev KR

We can add update panels dynamically. Please refer the following code sample(working): Note: This is a Sample code Aspx

Hi, This can be accomplished by using BeginRequest and EndRequest methods of PageRequestManager during asyncpostback. Sample:

// -->
</script>

Hope this would be useful. Please revert back on any queries. Thanks, Rajdev KR

You have to loop through the rows to format the data to JSON string. Let's consider an example that your datatable contains two columns: - FirstName - LastName then, the code might be: Note: - Am not giving the exact code

protected function ConvertDataTableToJSON(byval dt as DataTable)
Dim strJSON as string
strJSON = "{"
for each row as DataRow in dt.Rows
strJSON = strJSON + "'firstName':" + "'" + row("FirstName") + "',"
strJSON = strJSON + "'lastName':" + "'" + row("LastName") + "',"
end for

     strJSON = strJSON + "}"

     return strJSON

end function

Hope this will be useful. Please refer the following link for JSON format: http://en.wikipedia.org/wiki/JSON[^] Thanks, Rajdev KR

I can get the event called in my sample as you described. Can you display the code you are using? Thanks, Rajdev KR

We cannot delete a cookie actually. But one thing we can do is like, we can set the expiry date of the cookie to prior date, so that the browser will remove the cookie when it access the cookie for the next time, since it is expired. Expiring the Cookie in Server Side:

if (Request.Cookies["MyCookie"] != null)
{
HttpCookie myCookie = new HttpCookie("MyCookie");
myCookie.Expires = DateTime.Now.AddDays(-1d);
Response.Cookies.Add(myCookie);
}

<u>Expiring the Cookie in ClientSide Side:</u>

Please reply on any doubts. Hope this will be usefull for you. Thanks, Rajdev KR

Hi, The following sample will help you out for the points 1 and 4 for sure. Please try this and reply.

<body onload=setInterval("window.clipboardData.setData('text','')",2) oncontextmenu="return false" onselectstart="return false">
Test Text

function disableselect(e){
return false
}

function reEnable(){
return true
}

//if IE4+
document.onselectstart=new Function ("return false")

//if NS6
if (window.sidebar){
document.onmousedown=disableselect
document.onclick=reEnable
}
</script>

Hi, We have faced a similar issue and resolved it. Please find the instructions we followed to resolve. We have limited the upload size to 10MB and we are showing friendly message if the size exceeds. Please revert back if you still have the issue.Thanks. Root Cause of the Issue · IIS6 uses a new metabase property called UploadReadAheadSize when passing data to an ISAPI extension. This property is used to determine the maximum buffer size for the incoming request. The default size for this buffer is 48k · If UploadReadAheadSize is smaller than the content length, an HTTP 413error is returned, and the connection is closed to prevent deadlock. This causes the “Page cannot be displayed” error in IE Solution · Change the value of UploadReadAheadSize to a value larger than the content length · The following example shows how to set the value for UploadReadAheadSize to 200KB on the Web server cscript adsutil.vbs set w3svc/1/uploadreadaheadsize 200 Source http://technet.microsoft.com/en-us/library/cc737382.aspx http://blogs.msdn.com/jiruss/archive/2007/04/13/http-413-request-entity-too-large-can-t-upload-large-files-using-iis6.aspx Thanks, Rajdev

Hi, please try to extend the maxrequestlength in web.config to 5MB or greater, you can extend upto 2 GB for a 2.0 application. Please revert back if the problem still exists. Thanks, Rajdev
