DataTable sorting

Sort a DataTable is a very simple activity:

[VB.Net]

dt.DefaultView.Sort = "ColumnName"  'normal DataTable 

ds.Tables("TableName").DefaultView.Sort = "ColumnName"  'DataTable in DataSet

[C#]

dt.DefaultView.Sort = "ColumnName"  'normal DataTable

ds.Tables["TableName"].DefaultView.Sort = "ColumnName"  'DataTable in DataSet

With this snippet you don't "physically" order the content of the DataTable but it's default view. But for data visualization purpose and other the result is the same.

Using this DataTable, for example, as datasource for a GridView the list will be sorted based of the used criteria (ColumName).

UpdateProgress dinamically centered

<script language="JavaScript" type="text/javascript">

        function adjustDivs() {           

            internal= document.getElementById('divCalculateInt');

            external= document.getElementById('divCalculate');

            dfs = interno.style;

           

            dfs.left = (external.innerWidth - internal.offsetWidth) / 2;

        }

        window.onload = adjustDivs;

        window.onresize = adjustDivs;

        window.onscroll = adjustDivs;
