如何使用数据读取器在ASP.NET中为buuton添加commandname和commandargument值 [英] How to add commandname and commandargument value for buuton in ASP.NET using data reader

问题描述

<％MySqlCommand cmd = new MySqlCommand（sql，conn）;

MySqlDataReader read = cmd.ExecuteReader（）;

while（read.Read（））

{％>

 <   asp：按钮    ID   =  btnsubmit    OnClick   =  btnsubmitonclick   < span class =code-attribute> class   =  btn btn-primary < span class =code-attribute>     runat   =  server    tabindex   =  4 < span class =code-attribute>  文本  = 立即升级    /   >  

我尝试过：



上面的按钮我需要使用read [0] value

解决方案

添加commandname和commandargument值可能你的意思是这个（转到View代码）：

 受保护  void  Page_Load （ object  sender，EventArgs e）
 {
 btnsubmit.CommandName =  < span class =code-string> BlaBlaBla; 
 btnsubmit.CommandArgument =   Hehehe; 
} 

 <  < span class =code-leadattribute> asp：按钮    ID   =  btnsubmit    OnClick   =  btnsubmitonclick    class   =  btn btn-primary      runat   =  server    tabindex   =  4   文本  = 立即升级    CommandName   =  BlaBlaBla    CommandArgument   =  HeHeHe  /  >  

<% MySqlCommand cmd = new MySqlCommand(sql, conn);
MySqlDataReader read = cmd.ExecuteReader();
while(read.Read())
{%>

<asp:Button ID="btnsubmit" OnClick="btnsubmitonclick" class="btn btn-primary"  runat="server" tabindex="4" Text="Upgrade Now" />

What I have tried:

for the above button i need to add commandname and commandargument value using read[0] value

解决方案

Probably you mean this (go to View Code):

protected void Page_Load(object sender, EventArgs e)
{
  btnsubmit.CommandName = "BlaBlaBla";
  btnsubmit.CommandArgument = "Hehehe";
}

<asp:Button ID="btnsubmit" OnClick="btnsubmitonclick" class="btn btn-primary"  runat="server" tabindex="4" Text="Upgrade Now" CommandName="BlaBlaBla" CommandArgument="HeHeHe"/>
