How to Create Nested Gridview in Asp.net ~ Asp .Net Solution Kirit Kapupara

Description:-

What is Nested Gridview :-

Gridview Contain more than one other Gridview inside in it. It’s Called a nested Gridview.this type of Facility is provided by asp.net and are very useful to store All Detail in it.

For Example:-

            Suppose we have to Display student personal information and student Education Detail at that time one gridview can not capable of Displaying All information of student like personal and Education because of each contain more Field like Name,Age etc .. in personal information and Degree,Year,Result etc.. in Educational information so that type of information one Gridview can not Display in a proper manner because of screen Width. Due to this problem we are create a Nested Gridview in which parent Gridview contain student personal information and Child Gridview contain Educational Detail so all different type of information are store in proper way.

   in this Example we use the JQuery for Expand and Collapse the Gridview.in which there are two image plus.png and minus.png when click on plus.png the Gridview row is Expand and when click on the minus.png the Gridview row is Collapse.this is the code for Jquery are as Follow

For Ex:-

<script src="MenuScript.js" type="text/javascript"></script>

<script type="text/javascript">

$("[src*=plus]").live("click", function () {

$(this).closest("tr").after("<tr><td></td><td colspan = '999'>" + $(this).next().html() + "</td></tr>")

$(this).attr("src", "../0_Images/minus.png");

});

$("[src*=minus]").live("click", function () {

$(this).attr("src", "../0_Images/plus.png");

$(this).closest("tr").next().remove();

});

</script>

So main Advantage of this Example is that we can Display our data in a Proper way so our Website user can easily Understand and we can make a user Friendlly Website through this type of example.
