I have got a dataset.

C#

DataSet dataSet2 = new DataSet();

            SqlConnection conStr2 = new SqlConnection(ConStr);

            string queryString = "Select * FROM JoinTable";

            SqlDataAdapter daGlobalClass2 = new SqlDataAdapter(queryString, conStr2);

            conStr2.Open();

            daGlobalClass2.Fill(dataSet2, "myDataTable");

            conStr2.Close();

Mytable has 5 columns. One of them are TableA. Now I want to sort the dataset on the basis of column TableA. If the value of TableA is "mostusedtable" then those row will come first.

In the following way I can sort dataset.

C#

datatables1.DefaultView.Sort = "TableA";

But how can I sort this dataset on the basis of the value of column TableA ?

Solution 2

If you want to sort the data table:

C#

DataView view = datatables1.DefaultView;
view.Sort = "TableA";
DataTable sortedTable = view.ToTable();

If you want to sort de datagrid:

C#

    dataGrid1.Sort(dataGrid1.Colums[<index>]);
</index>

Hi,

You Need to add Another calculated Column in Select Query

like

SQL

string queryString = "
select (SELECT p.[Rows] FROM sys.tables t INNER JOIN   sys.indexes i ON t.OBJECT_ID = i.object_id INNER JOIN sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id WHERE t.NAME = tblRes.TableA AND i.OBJECT_ID > 255 AND i.index_id <= 1 ) as RowCount, tblRes.* from JoinTable as tblRes "

Then Sort That Data Table By RowCount Column

SQL

datatables1.DefaultView.Sort = "RowCount";

Thanks

Try This Code

DataView dv = ft.DefaultView;
dv.Sort = "occr desc";
DataTable sortedDT = dv.ToTable();
