.net中使用DatagridView的增删改方法

核心提示：//更新记录string sql = string.Format("delete dbo.GroupType_Demo where num={0}", Num);try{int i = SqlHelper.ExecuteNonQuery(SqlHelper.GetConnSting(), Comma

//更新记录
string sql = string.Format("delete dbo.GroupType_Demo where num={0}", Num);
try
{
int i = SqlHelper.ExecuteNonQuery(SqlHelper.GetConnSting(), CommandType.Text, sql);
if (i > 0)
{
ClientScript.RegisterStartupScript(ClientScript.GetType(), "myscript", "<script language='javascript'>alert('删除成功！')</script>");
}
else
{
ClientScript.RegisterStartupScript(ClientScript.GetType(), "myscript", "<script language='javascript'>alert('删除失败！')</script>");
}
}
catch (Exception ex)
{
ClientScript.RegisterStartupScript(ClientScript.GetType(), "myscript", "<script language='javascript'>alert('操作无效！')</script>");
}
GridView1.EditIndex = -1;
GridViewBind();
}
/// <summary>
/// 添加按钮
/// </summary>
protected void btnAdd_Click(object sender, EventArgs e)
{
Response.Redirect("~/Default_Add.aspx");
}
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
//行号
int i = e.NewSelectedIndex;
GridViewRow row = GridView1.Rows[e.NewSelectedIndex];

btnAdd.Text = "你选中了第" + (i+1) + "行。";
}
}
}
执行后的页面效果：
