推荐答案

GridView需要绑定到某种类型的数据源；数据表，列表或任何可枚举的对象.从文本框中获取值，将其放置在列表中并绑定到gridview.

The GridView needs to be bound to some type of datasource; a datatable, list, or any enumerable object. Take the values from the textboxes, place them in a list and bind to the gridview.

试试这个

Hi ,
try this

protected void Button1_Click(object sender, EventArgs e)
    {
        DataTable dt = new DataTable();
        if (GridView2.Rows.Count == 0)
        {
            dt = MakeTable();
            
        }
        else
        {
            dt =(DataTable) ViewState["dt"];
        }   
        DataRow dr = dt.NewRow();
        dr[0] = TextBox2.Text;
        dr[1] = TextBox3.Text;
        dr[2] = TextBox4.Text;
        dt.Rows.Add(dr);
        GridView2.DataSource = null;
        GridView2.DataSource = dt;
        GridView2.DataBind();
        ViewState.Add("dt", dt);
    }
    DataTable MakeTable()
    {
        DataTable Mydt = new DataTable();
        DataColumn col1 = new DataColumn("col");
        col1.DataType = System.Type.GetType("System.String");
        Mydt.Columns.Add(col1);

        DataColumn col2 = new DataColumn("col2");
        col1.DataType = System.Type.GetType("System.String");
        Mydt.Columns.Add(col2);


        DataColumn col3 = new DataColumn("col3");
        col1.DataType = System.Type.GetType("System.String");
        Mydt.Columns.Add(col3);
        return Mydt;
    }

或

OR

protected void Button2_Click(object sender, EventArgs e)
{
     string[] xx = new string[3];
    xx[0] = TextBox2.Text;
    xx[1] = TextBox3.Text;
    xx[2] = TextBox4.Text;
    GridView2.DataSource= xx.ToList();
    GridView2.DataBind();

}

<div>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<br />
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>
<asp:GridView ID="GridView2" runat="server">
</asp:GridView>
<br />
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />

</div>
