<LayoutSettings  AllowSelectColumns="Yes" AllowColumnMove="Yes" >

 <ClientSideEvents   OnColumnMove="WebGrid1_OnColumnMove"  />


</LayoutSettings>

//Get  the column which you are moving
  function WebGrid1_OnColumnMove(controlId, tblName, sourceIndex, targetIndex, sourceColumn, targetColumn) {
       alert("the Move Column Name is：" + sourceColumn.Name);
        }

May be, the Way you will use later

Do you want this ?:
Js Code:

    <script type="text/javascript">
        function setForColor() {

            var grid = ISGetObject("WebGrid1");

            for (var i = 0; i < grid.TotalRows; i++) {

                var row = grid.RootTable.GetRow(i);
                var rowElement = row.GetElement();
                rowElement.style.color = "red";
           
            }      
   
        }
    </script>

C# code:

//Set webgrid BackColor 
      protected void Button1_Click(object sender, EventArgs e)
    {
        WebGrid1.LayoutSettings.AlternatingColors = false;
        WebGrid1.RootTable.RowStyle.BackColor = Color.Red;
