ASPX页面中的样式问题

Question

I have an ASPX page that is suppose to output 5 instances of one custom control (basically a table with data grabbed from a database). I am relatively new to ASP.NET as well as JavaScript, so I am having some difficulty fixing this styling issue.

My problem is that, styling on the custom control (the table) is only being applied to the first instance of the control. I am not sure why that is. I have put my code up (I renamed a lot of things to keep this generic). How would I go about making the styling apply to all 5 instances?

    </script>

From a bit of playing around, if I commented out attachDataTablesToSomethingTable() from the JavaScript call at the bottom, then no styling was applied to any table, so I assume that is the function that applies/calls the styling. Again, I am inexperienced with ASP.NET and JavaScript, so if anyone could shed any light, that would be awesome.

Answer 1

I'll agree with @lucuma's comment to your question. So, I may suggest you to implement unique id for table of each custom control instance. This can be achieved by implementing a public property say 'TableID' in your custom control, which can be configured for each custom control instance.

The below parts go into user custom control implementation:

Code behind:

public string TableID
{
   get;
   set;
}

Markup:

<table id='<%=TableID %>'>

Configure the TableID property for each custom control instance in aspx page:

<company:Control3 ID="control3First" runat="server" meta:resourcekey="control3First" Filter=""
TableID='mytable1' />

<company:Control3 ID="control3Second" runat="server" meta:resourcekey="control3Second" Filter=""
TableID='mytable2' />

And finally, wire up jquery plug-in for each table...

mytable1 = $('#mytable1').dataTable(...);
mytable2 = $('#mytable2').dataTable(...);

Hope this helps...
