问题描述

当单击下面的链接按钮时，我想在绑定后向 gridview 添加一个新的空白行，如图所示.如果在其中输入了任何数据，则 gridview 内的文本框应保持不变.只想添加一行.请帮我.提前致谢.

I want to add a new blank row to the gridview after binding as seen in the picture when clicking the link button below. The textboxes inside the gridview should remain the same if there is any data entered in it. just want to add one row. please help me. Thanks in advance.

推荐答案

可以试试下面的代码

protected void Button1_Click(object sender, EventArgs e)
   {
       DataTable dt = new DataTable();

       if (dt.Columns.Count == 0)
       {
           dt.Columns.Add("PayScale", typeof(string));
           dt.Columns.Add("IncrementAmt", typeof(string));
           dt.Columns.Add("Period", typeof(string));
       }

       DataRow NewRow = dt.NewRow();
       NewRow[0] = TextBox1.Text;
       NewRow[1] = TextBox2.Text;
       dt.Rows.Add(NewRow); 
       GridView1.DataSource = dt;
       GridViewl.DataBind();
   }

这里的payscale、incrementamt 和 period 是数据库字段名.

here payscale,incrementamt and period are database field name.
