C# ASP.NET Ajax example

I would like to have a C# ASP.net page created that illustrates AJAX and partial page rendering and updating. This is going to be used as an example so the more clear the coding the [login to view URL] end result will be a aspx and an [login to view URL] file (or a VS 2010 or higher project with these two files in them). Specifically the page will need to contain two main controls a DataGrid at the top of the page and a 3 Tab panel at the bottom of the page. Each of the 3 tabs will have a table with data and a button in them that will cause an update to occur (in code behind). The data grid should only load its data 1 time when the page loads (from code behind) The tab pages should not have any data loaded in them initially (the data will load only when a row is clicked in the data grid) The data grid should allow each row to be selected When the data grid row is selected the first tab of the tab panel should load a set of data (in code behind) for the 1st tab only. The data grid should NOT refresh or reload any data nor should any of the other tab pages (except for the one that was just selected). When the 2nd tab button is selected the data should be loaded and displayed for the second tab (again from code behind). The data grid should NOT refresh or reload any data nor should any of the other tab pages (except for the one that was just selected). When the 3rd tab is selected the data should be loaded and displayed for the third tab only (from code behind). The data grid should NOT refresh or reload any data nor should any of the other tab pages (except for the one that was just selected). Each time a button is clicked on the tab to update the data only the data from the table should be transmitted to the server no data from the data grid or the other tabs should be transmitted to the server. Similarly only the data on that tab should be reloaded after the button click occurs. An example is attached (docx) that shows the Data grid at the top and the 3 tab page at the bottom for reference. Please know that what I am looking for may not be possible to develop to the standard requested above.
