This is because you referred to cell-0 only.

You need to loop to get all the column headers.
Try:

JavaScript

function readgrid() {
    var grid = document.getElementById('<%= GrdDynamic.ClientID %>');

    alert("Header 1:" + grid.rows[0].cells[0].innerHTML);
    alert("Header 2:" + grid.rows[0].cells[1].innerHTML);
    alert("Header 3:" + grid.rows[0].cells[2].innerHTML);
    alert("Header 4:" + grid.rows[0].cells[3].innerHTML);
    alert("Header 5:" + grid.rows[0].cells[4].innerHTML);
    alert("Header 6:" + grid.rows[0].cells[5].innerHTML);
    alert("Header 7:" + grid.rows[0].cells[6].innerHTML);
    alert("Header 8:" + grid.rows[0].cells[7].innerHTML);
}

You can have a for loop and get it:
