C＃（对象发送者，GridViewCommandEventArgs e）如何为第二部分做些过分的准备？

Question

I got the following Code:

protected void Name_RowCommand(object sender, GridViewCommandEventArgs e)

{
    if (e.CommandName == "TextINeed")
    {
        //Some Code
    }

    if (e.CommandName == "SomethingElse")
    {
       //Some Code
    }
}

protected void btn_someButton(object sender, EventArgs e)
{
    Name_RowCommand(sender, "TextINeed");
}

The Problem i have is with the Name_RowCommand(sender, "TextINeed"); I know that (sender, should be right, but how do i make the 2nd part right? I tried a few things but nothing worked so far.

I'm happy about any advice!

I assume this is ASP.NET due to the GridViewCommandEventArgs . You can't pass arguments to events directly. Events are triggered. In this case you have to register this event handler, for example on aspx:

<asp:gridview id="GridView1" 
  onrowcommand="Name_RowCommand"
  runat="server">

  <columns>
    <asp:buttonfield buttontype="Link" 
      commandname="TextINeed" 
      text="SomeText"/>
   .....
  </columns>

</asp:gridview>

If the user now clicks on the link-button the CommandName will be TextINeed .

If you want to call the code inside of an event handler from another one you should create a method that you can call from both event handlers.

private void MyFirstMethod()
{
    //Some Code
}

protected void Name_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "TextINeed")
    {
        MyFirstMethod();
    }
}

protected void btn_someButton(object sender, EventArgs e)
{
    MyFirstMethod();
}
