ASP.NET ships with 45 built in Server Controls. These controls are capable of exposing an object model containing properties, methods, and events. ASP.NET developers can use this object model to cleanly modify and interact with the page.
This code with respect to one of the queries in the newsgroup. Normally we get the data displayed in the following manner :
Header1
Header2
Header3
Data
Data
Data
Data
Data
Data
Header1
Data
Data
Header2
Data
Data
Header3
Data
Data
Let's try to achieve this. The control that would be appropriate to display such a kind of page would be Table Control.
The following code is to access the data:
Dim
mycn As SqlConnectionDim myda As SqlDataAdapter
Dim ds As DataSet
mycn = NewSqlConnection
"server=localhost;uid=sa;password=;database=northwind")
myda = New SqlDataAdapter("Select Employeeid, FirstName , LastName from employees", mycn)
ds = New DataSet()
myda.Fill(ds, "Employees")
To display the data in the desired manner the code is as follows.
Dim
dc As DataColumnDim dr As DataRow
For Each dc In ds.Tables(0).Columns
Dim trow As New TableRow
Dim tcellcolname As New TableCell
'To Display the Column Names
For Each dr In ds.Tables(0).Rows
tcellcolname.Text = dc.ColumnName
trow.BackColor = System.Drawing.Color.Beige
tcellcolname.BackColor = System.Drawing.Color.AliceBlue
'Populate the TableCell with the Column Name
tcellcolname.Controls.Add(New LiteralControl(dc.ColumnName.ToString))
Next
trow.Cells.Add(tcellcolname)
'To Display the Column Data
For Each dr In ds.Tables(0).Rows
Dim tcellcoldata As New TableCell
'Populate the TableCell with the Column Data
tcellcoldata.Controls.Add(New LiteralControl(dr(dc.ColumnName).ToString)) trow.Cells.Add(tcellcoldata)
Next
Table1.Rows.Add(trow)
Next
So the output that we get is as follows:
Employeeid
1
2
3
4
5
6
7
8
9
FirstName
Nancy
Andraw
Janet
Margreat
stevan
Micheal
Robart
Laura
Anne
LastName
Davlivo
Fuller
Leavring
Peacock
Bucchan
Suyama
King
Callahan
