Server-side button click - client side implementation

Recently, I had to override the server-side button OnClick function for a button but unfortunately and I hope you do NOT come across this scenario, but the source code file, the C# file went MISSING.

Yes, I could have use DotNet Reflector to recover the code but I was under a very quick deadline, so here is my approach.

Use jQuery!

What you have to do is to assign a unique CssClass name for the button, which can still be done with just the .aspx file.

And include jQuery as per normal the crucial part is when you declare the jQuery document.ready function, include the following within the document.ready function.

That way, you override the ASP.Net page life cycle, thus when you click the button, this code snippet runs first.

$("input.[insert_unique_css_class_here]").click(function() {
//Validate some other controls. You will have to implement the validateChkBox and validateDdl functions.
var postBackRequired = false;
var postBackIfCbChecked = validateChkBox();
var postBackIfDdl = validateDdl();

if (postBackIfCbChecked && postBackIfDdl) {
postBackRequired = true;
}

return postBackRequired;
});

Repeater Paging - Paged Data Source

Recently I was experimenting with paging and repeaters and managed to solve it with a PagedDataSource object.

There are certain rule that come with this, however.

After instantiating a PagedDataSource object, it is PIVOTAL to set the DataSource property directly after it, before using other properties of the PagedDataSource class.

The way I implemented it was as follows.

Have 1 repeater that will contain the list of data that would like to display.

Also, I've used a repeater approach to implement the paging numbers rather than having just the 1 page number and having 2 links that will go forward and backward.

I've also maintained the page number using a public property with ViewState holding the value of the current page.
