The GridView has an AutogenerateColums-property for this purpose.
You could also generate the Columns on the fly, for example:
VB.NET
Dim tbl As New DataTable
tbl.Columns.Add("ID", GetType(Int32))
tbl.Columns.Add("Name", GetType(String))
tbl.Columns.Add("Birthday", GetType(Date))
Dim pers As DataRow = tbl.NewRow
pers("ID") = 1
pers("Name") = "Tim"
pers("Birthday") = New Date(1973, 6, 9)
use AutoGenerateColumns
to let grid generate the column itself:
Me.GridView1.AutoGenerateColumns = True
Me.GridView1.DataSource = tbl
Me.GridView1.DataBind()
or generate the columns dynamically
For Each col As DataColumn In tbl.Columns
Dim field As New BoundField
field.DataField = col.ColumnName
field.HeaderText = col.ColumnName
GridView1.Columns.Add(field)
Next
C#
foreach (DataColumn col in dt.Columns)
{
BoundField field = new BoundField();
field.DataField = col.ColumnName;
field.HeaderText = col.ColumnName;
GridView1.Columns.Add(field);
}
