如何从文本框在非空网格视图中添加更多数据. [英] How to add more data in a non empty grid view from a text box....

问题描述

亲爱的朋友，快乐洒红节

朋友，我有2个文本框，1个按钮和1个网格视图，

我已经使用以下代码从文本框(第一次网格视图为空)输入了一些记录到datagridview中..

Dear Friends Happy holi

friends i have 2 Text box, 1 button and 1 grid view ,

i have enter some record into datagridview from text box (first time grid view is empty)using the following code..

DataTable MyTable = new DataTable();
                DataColumn values = new DataColumn("Column1");
                DataColumn values1 = new DataColumn("Column2");
               
                MyTable.Columns.Add(values);
                MyTable.Columns.Add(values1);
               

                DataRow rd = MyTable.NewRow();
                rd[0] = textBox1.Text;
                rd[1] = textBox2.Text;
                MyTable.Rows.Add(rd);
                dataGridView1.DataSource = MyTable;

但是，当我尝试添加更多记录时，例如单击确定"按钮g，然后在网格视图上添加记录，并且文本框为空，然后在文本中输入一些内容，然后单击确定"按钮，然后将新记录追加到旧记录下.但是当我使用此代码时，数据将被覆盖.

我想在网格视图不为空时每次都向网格视图中添加新行...

请通过在此处提供代码来提供帮助.在此先感谢....

推荐答案

您需要先将列添加到表中，然后才能添加行.

you need to add the columns to the table before you can add rows.

        DataTable dt = new DataTable();
        DataColumn dc = new DataColumn("name");
        dt.Columns.Add(dc);
        dc = new DataColumn("field");
        dt.Columns.Add(dc);
//Now your table has defined columns
// you can add rows...
 
        DataRow dr = dt.NewRow();
        dr["Name"] = TextBox1.Text;
        dr["field"] = TextBox2.Text;
 
        GridView1.DataSource = dt;
        GridView1.DataBind();
