[Code]....
Lastly, the albumID and photoID will pass to the photopage.aspx to display the image
[Code]....
But when i wanted to view the image in photopage.aspx, it shows a blank page. No error and nothing comes out.
In the main code, I just have a panel inside a DataList control. I'm attempting to adjust change the visibility to true or false in the code behind, but it's not having any affect on the panel.
I'm using a jquery plugin called uploadify to upload images to my database. I'd like my datalist to be auto-rebind after the images' been uploaded so people could see the changes immediately. Also because this is a feature for admin there is a delete button in the datalist. I used updatePanel for this.
I put __doPostBack('" + upnlUploaded.ClientID + "','') to the javascript so when Images have been uploaded the update panel will postback.
I also have the following two lines to make it working...
I am having a button inside a datagrid and in the button content i have placed a image.I tried to change the souce of the image from datagrid list but the image is not binding. I used MVVM Model .
My observation so far in the output rendered by a datalist (when I use this user control inside it) is that the value for the name attribute is the same.I want to use this control inside a datalist/repeater such that I'd want a unique value for the input element's name attribute when the datalist/repeater renders. How is this done?
EDIT: My bad obversation. Actually the names are unique. However, when I try to post the page to another web page which outputs the key & value of all the items in Request.Form I don't see the input elements...
I am trying to place a datalist inside datalist. I managed to place a datalist inside gridview but not datalist inside datalist.
Below is the code I am using to bind the datalist into the master gridview, I am trying to change this code in such way it will be right for datalist inside datalist but so far I did not succeed.

Click Me in a UserControl. I downloaded the sample attached there and its working fine but i am trying to create UserControl out of it. No rows are getting loaded on scrolling down. I modified the code to look like this..
var lastProductId = $("#<%=Test1.GridView1.ClientID %> tr:last").children("td:first").html(); //get last table row in order to append the new products var lastRow = $("#<%=Test1.GridView1.ClientID %> tr:last"); AND,
function GetRowsCount() { //Count no. of rows except header row in the grid. var rowCount = $('#<%=Test1.GridView1.ClientID %> tr').length - 1; return rowCount;
Its giving me error: The name 'Test1' does not exist in the current context. Test1 is the Id of my USerControl. Test1 is the ID of UserControl. I found your tutorial on similar issue but i did not use it because i am not using stored procedure and i know nothing about XML. At this point i just want to make the sample attached in that article(one i provided) to work as a UserControl.
