Hi,
how can I create a cutom data table for gridview where row increases automatically and first row displays when user click on add button that is outside from grid?

推荐答案

创建数据表首先，然后将表格绑定到您的gridview上
DataTable dtAddGridView = new DataTable("TestTable");
受保护的void Add_Click(对象发送者，EventArgs e)
{

Create a datatable first and then bind the table on your gridview
DataTable dtAddGridView = new DataTable("TestTable");
protected void Add_Click(object sender, EventArgs e)
{

if (dtAddGridView.Rows.Count != 0)
        {
            if (dtAddGridView.Columns.Count != 0)
            {
                dtAddGridView.Columns.Add("Name", typeof(string));
                dtAddGridView.Columns.Add("ID", typeof(int));
                dtAddGridView.Columns.Add("Date", typeof(DateTime));
            }

}
DataRow dr = dtAddGridView.NewRow();

dr ["Name"] ="test";
dr ["ID"] = 100;
dr ["Date"] = DateTime.Now;

dtAddGridView.Rows.Add(dr);
GridView1.DataSource = dtAddGridView;
GridView1.DataBind();
}

}
DataRow dr = dtAddGridView.NewRow();

dr["Name"] = "test";
dr["ID"] = 100;
dr["Date"] = DateTime.Now;

dtAddGridView.Rows.Add(dr);
GridView1.DataSource = dtAddGridView;
GridView1.DataBind();
}
