How do i perform the same with only one hit from sql.?

Answer 1

You can do the following:

Use a stored procedure to return two results set for the following queries

SELECT DISTINCT StudentCode, studentname FROM StudentInfo

SELECT StudentCode, student name, Asset Details

Create a DataSet for the results with 2 tables. You can name the first table "Student" and the second table "StudentInfo"

Create a relationship for the tables (please use the intellisense for syntax)

DataSet.Relationships.Add("RelationshipName",Table1.StudentCode,Table2.StudentCode)

Bind the GridView with the DataSet

Create a Template column for Asset Details and insert a repeater or Gridview for that column.

On the ItemDataBound event of the GridView.

DataRowView drv = (DataRowView)e.ItemData;
Repeater.DataSource = dv.CreateChildView();
