如何在按钮上单击页面加载时调用方法 [英] How to Call a Method on Page Load at a Button Click in Asp.net

问题描述

我在Button中有一个方法.现在，我想在Page Load中使用此方法.
那怎么可能呢?
Mwthod name = OnlyRead();

我正在尝试吗?有一些错误吗?那是正确的吗?

代码-

I have a method in a Button. Now I want to use this metod at Page Load.
So How it is possible?
Mwthod name= OnlyRead();

I am trying this ? It havesome error? so what is right?

Code--

protected void Page_Load(object sender, EventArgs e)
    {
      Onlyread();
    {
        int rowIndex = 0;
        SqlConnection conn = new SqlConnection(connectionString);
        StringBuilder sb = new StringBuilder(string.Empty);

        try
        {
            int count = GridView2.Rows.Count;
            for (int i = 0; i < count; i++)
            {
                TextBox box11 = (TextBox)GridView2.Rows[rowIndex].Cells[0].FindControl("TextBox11");
                TextBox box13 = (TextBox)GridView2.Rows[rowIndex].Cells[1].FindControl("TextBox13");
 

                rowIndex++;
                box11.ReadOnly = true;
                box13.ReadOnly = true;
               


            }
        }
        catch (System.Data.SqlClient.SqlException ex)
        {
            string msg = "Error:";
            msg += ex.Message;
            throw new Exception(msg);

        }
           }
}
protected void BtnSave_Click(object sender, EventArgs e)
  {
OnlyRead();
}

推荐答案

protected void Page_Load(object sender, EventArgs e)
{
 if (Page.IsPostBack)
  {
     OnlyRead();
  }
}
private void Onlyread()
{
        int rowIndex = 0;
        SqlConnection conn = new SqlConnection(connectionString);
        StringBuilder sb = new StringBuilder(string.Empty);
 
        try
        {
            int count = GridView2.Rows.Count;
            for (int i = 0; i < count; i++)
            {
                TextBox box11 = (TextBox)GridView2.Rows[rowIndex].Cells[0].FindControl("TextBox11");
                TextBox box13 = (TextBox)GridView2.Rows[rowIndex].Cells[1].FindControl("TextBox13");
 
 
                rowIndex++;
                box11.ReadOnly = true;
                box13.ReadOnly = true;
               
 

            }
        }
        catch (System.Data.SqlClient.SqlException ex)
        {
            string msg = "Error:";
            msg += ex.Message;
            throw new Exception(msg);
 
        }
           }
}
protected void BtnSave_Click(object sender, EventArgs e)
  {
OnlyRead();
}

protected void Page_Load(object sender, EventArgs e)
{
 if (Page.IsPostBack)
  {
     OnlyRead();
  }
}

and write your onlyread() method and just call it from btnclick.
protected void BtnSave_Click(object sender, EventArgs e)
  {
    OnlyRead();
  }

只需编写:

Just write :

protected void Page_Load(object sender, EventArgs e)
{
   BtnSave_Click(null,null);
}

注意:但是亲爱的，如果您使用的是C#，我可以期望像这样的问题.了解有关C#的更多信息
