推荐答案

尝试如下

try like below

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DataTable dt =GetTable();
            GridView1.DataSource = dt;
            GridView1.DataBind();
            ViewState["Table"] = dt;
        }

    }


    protected void Button1_Click(object sender, EventArgs e)
    {
        int index = GridView1.SelectedIndex;
        //you may need to validate the index
        DataTable dt = (DataTable)ViewState["Table"];
        DataRow row = dt.NewRow();
        dt.Rows.InsertAt(row, index);
        dt.AcceptChanges();
        GridView1.DataSource = dt;
        GridView1.DataBind();
        ViewState["Table"] = dt;
    }

试用此代码：



DataTable dt = new DataTable（）;

DataRow dr = dt.NewRow（）;

dr [0] = TextBox1.Text;

dt.Rows .Add（dr）;

Gridview1.DataSource = dt;

Gridview1.DataBind（）;

Try this code:

DataTable dt = new DataTable();
DataRow dr = dt.NewRow();
dr[0] = TextBox1.Text;
dt.Rows.Add(dr);
Gridview1.DataSource = dt;
Gridview1.DataBind();
