Answer 1

protected void showNewsData_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "imgbutAlterDate")//编辑数据   
{
//我想在这里得到鼠标当前在哪一行，是指在GridView第几行数据
Control control = e.CommandSource as Control;
GridViewRow row = control.NamingContainer as GridViewRow;
Response.Write(row.RowIndex);
}
}

Answer 2

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ImageButton ibtn = e.Row.FindControl("ibtn") as ImageButton;
            if (ibtn != null)
            {
                ibtn.CommandArgument = e.Row.RowIndex.ToString();
            }
            
        }
    }
protected void ibtn_Click(object sender, ImageClickEventArgs e)
    {
        string str;
        ImageButton ibtn = sender as ImageButton;
        if (ibtn != null)
        {
            str=ibtn.CommandArgument;
        }             
    }
