后面的代码，但要填充detailview asp.net控件 [英] code behind but to populate detailview asp.net control

问题描述

嗨
我正在尝试填充asp.net detailview控件，但我只希望在单击按钮后显示该控件，该控件将发送ID以便从文本框中搜索记录

预先感谢您

Hi
I''m trying to populate a asp.net detailview control but I only want it to be displayed after a button click which will send the ID to search for the record from a textbox

Thank u in advance

推荐答案

首先，您需要从文本框中获取ID:-

First you need to get the Id from text box:-

int id = Convert.ToInt32(txtId.Text);

然后在button_Click上:-

Then On button_Click :-

Protected void button_Click(object sender, EventArgs e)
{
  SqlConnection con = new SqlConnection("your connection string");
  SqlCommand cmd = new SqlCommand("SELECT * FROM [table_Name] WHERE Id=@Id",con)
  cmd.Parameters.AddWithValue("@Id",id);
  //id is your value retrieved from textbox.
  SqlDataAdapter da = new SqlDataAdapter(cmd);
  DataSet ds = new DataSet();
  da.Fill(ds);
  //now bind the datasource with DetailsView Control.
  detailsView1.DataSource = ds;
  detailsView1.DataBind();
}

希望对您有帮助.
祝您好运.

Hope it will help you.
Best of luck.

我不明白您为什么坚持执行它.

步骤:
1.在aspx文件中定义一个detailView控件并将其可见性设置为false.
2.定义一个按钮控件.单击它，获取detailsView的数据，然后在后面的代码中将其Visible属性设置为true.

完毕！试试吧！

I don''t see why you are stuck in implementing it.

Steps:
1. Define a detailView control and set it''s visibility to false in your aspx file.
2. Define a button control. On click of it get data for detailsView and then set it''s Visible property to true in code behind.

Done! Try!
