问题描述

IN Cs

IN Cs

protected void Page_Load(object sender, EventArgs e)
   {
       if (!IsPostBack)
       {
           TextBox1.Focus();
           gvbind();
       }
   }
       private void gvbind()
       {
           obj.type=0;
           ds = obj.DataSet();
           GridView1.DataSource = ds;
           GridView1.DataBind();}

在Sql server中

In Sql server

if @type=0
select * from app

推荐答案

尝试像这样的BindGrid



private void BindGrid（）

{

DataSet ds = new DataSet（）;

SqlConnection Conn = new SqlConnection（con）;

{

Conn.Open（）;

SqlCommand cmd = new SqlCommand（Select * from ProductInfo，Conn）;

SqlDataAdapter da = new SqlDataAdapter（cmd）;

da.Fill（ds）;

Conn.Close（）;

gvDetails.DataSource = ds;

gvDetails.DataBind（）;



}

}

Try BindGrid Like This

private void BindGrid()
{
DataSet ds = new DataSet();
SqlConnection Conn = new SqlConnection(con);
{
Conn.Open();
SqlCommand cmd = new SqlCommand("Select * from ProductInfo",Conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
Conn.Close();
gvDetails.DataSource = ds;
gvDetails.DataBind();

}
}

你好，



立即postba ck响应按钮点击你没有调用gvBind（）所以它看起来你无法获得并看到gridview控件。你需要调用gvBind（），如下所示，每次回发或非回发意味着首先加载你应该能够绑定数据看看网格控件。你可以尝试如下 -

Hi,

On immediate postback in response to button click you are not calling gvBind() so it looks you are not able to get and see gridview control. You need to call gvBind() as below so on every postback or non-postback means first load you should be able to bind data see grid control. Can you try as below -

protected void Page_Load(object sender, EventArgs e)
{
   if (!IsPostBack)
   {
      TextBox1.Focus();
   }
   gvbind(); // on every page load it will bind data to grid control.
}
