问题描述
我有一个Form，它正在计算和显示我正在使用的TexBox es中的数据，用于进一步计算，现在在保存Button Click上，我有这段书面代码:
I have a Form which is calculating and displaying data in TexBoxes which I''m using for further calculation, now on Save Button Click I have this written code:
DataTable dt = new DataTable();
DataRow drow = dt.NewRow();
DataColumn dc = new DataColumn("X", typeof(System.String));
DataColumn dc1 = new DataColumn("Y", typeof(System.String));
DataColumn dc2 = new DataColumn("Z", typeof(System.String));
dt.Columns.Add(dc);
dt.Columns.Add(dc1);
dt.Columns.Add(dc2);
string[] rows = { "" + textBox10.Text, "" + textBox11.Text, "" + textBox12.Text };
dt.Rows.Add(rows);
dataGridView1.DataSource = dt;
一切正常，只是我希望每次将值保存到新行时都保存而不覆盖先前的行，如:
r1 11 111 111
r2 22 11 1111
...
etc
It is working fine except that I want on save each time value gets saved to new row without overwriting the previous like:
r1 11 111 111
r2 22 11 1111
...
etc
推荐答案
string[] rows = { "" + textBox10.Text, "" + textBox11.Text, "" + textBox12.Text };
dt.Rows.Add(rows);
BindGrd();
4. BindGrid()
公共无效dataGridView1.DataSource = dt;
BindGrd();
4. BindGrid()
public void dataGridView1.DataSource = dt;
