我使用7个组合框和文本框来显示某些项目 我有DataTable中的数据。所以我将数据表绑定到组合框和文本框,如
cmbIngredient1.DataSource = dt;
cmbIngredient1.DisplayMember = "Ingredient";
cmbIngredient1.ValueMember = "Ingredient";
txtTotalIngre1.DataBindings.Clear();
txtTotalIngre1.DataBindings.Add("Text", dt, "No Of Pieces");
cmbIngredient2.DataSource = dt;
cmbIngredient2.DisplayMember = "Ingredient";
cmbIngredient2.ValueMember = "Ingredient";
txtTotalIngre2.DataBindings.Clear();
txtTotalIngre2.DataBindings.Add("Text", dt, "No Of Pieces");
//Similar code for all 7 combobox and textboxes.//
正在显示数据。但是当我改变其中的combobox1其他组合框项目也在改变..
我想要这样:当更改了combobox1项目时,只应更改textbox1 当comboxbox2项目更改时,textbox2应该更改。
我是否需要创建单独的数据表并绑定以实现此目的?
答案 0 :(得分:0)
我通过将数据表复制到另一个Datatable
实例来解决这个问题DataTable dt2 = dt;
cmbIngredient2.DataSource = dt2;
cmbIngredient2.DisplayMember = "Ingredient";
cmbIngredient2.ValueMember = "Ingredient";
txtTotalIngre2.DataBindings.Clear();
txtTotalIngre2.DataBindings.Add("Text", dt2, "No Of Pieces");
