ASP.NET - Almost complete use of Datagrid

I was on a need of creating datagrid object on my page with sorting, filtering, updating needs. You could make use of below example for some complex cases (Dropdown, Date selector update columns for relational data table updates, filters, multiple update queries)

    <table border="0" cellspacing="0">
        <tbody>
<tr>
        <th>Owner_Name</th>
        <th>OS</th>
        <th>Type</th>
        <th>Status</th>
        <th>Action Type</th>
        </tr>
<tr>
        <td><asp:dropdownlist appenddatabounditems="true" autopostback="true" datasourceid="dsPopulateOwner_Name" datatextfield="UNAME" datavaluefield="UID" font-size="11px" id="ddlOwner_Name" runat="server" width="130px">

VBScript for URL link creation

We had a need to create URL link of our project on users's desktop using a script.

MySQL Dump cronjob on linux server

No spaces, unless its required. in between -u and user name, there is a space, but no space between -p and password. As per the usage of system, we can decide on which interval the cronjob could be set. normally the format of a crontab entry is like the following. * * * * * /apps/scripts/scheduled_job.sh >> /dev/null 2>...
