Highlighting Gridview Row on Mouse Over which does not have Alternating Row Color.

Suppose,we have a Gridview called grid_project_details as below:-

<asp:GridView ID = "grid_project_details" runat = "server" 
OnRowCreated = "grid_project_details_RowCreated">
</asp:GridView>

Now in the OnRowCreated event we have to write below code:-

protected void grid_project_details_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //On Mouse Over Highlight Row set row color to yellow
        e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='yellow'");

        //On Mouse out restore default row color i.e. white color
        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='white'");
    }
}

So,when we point our mouse on any row,color will be yellow and point out,then reset color as white.
