推荐答案

请尝试如下。



注意：这只是一个示例。请根据您的具体情况进行更改。

Please try is as below.

Note : This is just a sample.Change it according to your situation.

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

       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();
   }

在按钮上向GridView添加新行在ASP.Net中单击

绑定到网格的数据表，假设数据表是dtGrid。将其保存在ViewState / Session中

下面我提供了一个示例代码。我希望这给你一个构思的基础......

这段代码将添加空行...

The datatable bound to the grid, assume the datatable is dtGrid. Save that in a ViewState/Session
Below I have provided a sample code. I hope this gives you an idea to build on...
This code will add empty row...

OnAddNew_Click()
{
dtGrid=(DataTable)ViewState["dt"];
DataRow dr = dtGrid.NewRow();
dr[0]=""
dr[1]=""
dr[2]=""
dr[3]=""
dr[4]=""
dtGrid.Rows.Add(dr);
gridView.DataSource=dtGrid;
gridView.DataBind();
}

希望这有帮助
