Empty textbox in grid showing square brackets
<p>We have a scenario wherein we have a editable gridview. Users enter data and submit. On submission we send the grid data as html in an email. The issue we are facing is that if a textbox is left empty it shows [    ] square brackets. These look very annoying. Kindly see screenshot the last bottom box is highlighted in red.</p>

<p>Kindly let know how we can make that square brackets gp away / donot show up.<a href="https://i.stack.imgur.com/fP2Kw.png" rel="nofollow"><img src="https://i.stack.imgur.com/fP2Kw.png" alt="enter image description here"></a></p>
