Is there a way to trigger a GridView rebind from an html markup page using jQuery or jscript?
I have an ActiveX download control which passes all events via jscript.
So, a have a download complete event on the markup page but not the code behind.
Thank you,
James
Here is the main aspx page:
<script type="text/javascript">

//The file list is going to be downloaded - "2 = About to Start"
if (Step == 2){
//Dynamically build the filelist for the downloader
getFileDownloader("FileDownloader").setFileList("GetFileList.aspx");
}
//The user has confirmed the download - "6 = File Download About to Start"
if (Step == 6){
//Perform the initialization updates to the first file only
var xmlhttp;
if (typeof XMLHttpRequest != 'undefined') {
xmlhttp = new XMLHttpRequest();
}
if (!xmlhttp) {
throw "Browser doesn't support XMLHttpRequest.";
}
var data = "";
xmlhttp.open("POST", "UpdateVideoInitiated.aspx", true);
//Send the proper header information along with the request
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
//xmlhttp.setRequestHeader("Content-length", data.length);
xmlhttp.setRequestHeader("Connection", "close");
xmlhttp.send(data);
}
}
function onDownloadItemComplete(Result, ErrorPage, Url, FileName, ContentType, FileSize){
var xmlhttp;
var data;
//The handler will display the error description or updates as noted
switch (Result){
