You can use DefaultView.RowFilter also

myDataTable.DefaultView.RowFilter = "ID = 2"

So how can i get the value in column 5 after the
myDataTable.DefaultView.Ro
myDataTable.DefaultView.Ro
DataRow[]Rows = DataTable.Select("ID = 2","");
Rows[0][5] would give the value in column five in row 0.
Rows[0][5] would give the value in column five in row 0.
using DataColumn Expression you can do something like
DataSet1.Tables("Orders").
look at: http://msdn.microsoft.com/en-us/library/system.data.datacolumn.expression.aspx
DataSet1.Tables("Orders").

When i tried entering
DataRow[]Rows = DataTable.Select("ID = 2","");
the . Select is not in the list...the list consist of only Equals and ReferenceEquals
DataRow[]Rows = DataTable.Select("ID = 2","");
the . Select is not in the list...the list consist of only Equals and ReferenceEquals
try:
DataSet1.Tables("TableName
DataSet1.Tables("TableName
Change DataTable to your DataTable object, don't just use the class name:
DataRow[] Rows = myDataTable.Select("ID = 2","");
DataRow[] Rows = myDataTable.Select("ID = 2","");

i tried
DataRow[] Rows = ordt.Select("ID = 2", "");
comboBox1.Text = ordt.Rows[0][5].ToString()
but again the same error came out" there is now row at position 0"
DataRow[] Rows = ordt.Select("ID = 2", "");
comboBox1.Text = ordt.Rows[0][5].ToString()
but again the same error came out" there is now row at position 0"
