Question

我在下面的链接中检查了问题： This causes two bindings in the collection to bind to the same property. Parameter name: binding error in c#?

我按照给出的答案。错误消失但有一个新问题：

有一个DGV，当我点击它的单元格时，一些文本框绑定到所选行。当我点击之后的其他行时，它会清除DGV中的第一行。

代码：

                    this.SupportPersonnelIDtxt.DataBindings.Clear();
                    this.SupportCallingPersontxt.DataBindings.Clear();
                    this.SupportCustomerProductIDtxt.DataBindings.Clear();
                    this.SupportIssuetxt.DataBindings.Clear();
                    this.SupportServicetxt.DataBindings.Clear();
                    this.SupportResulttxt.DataBindings.Clear();
                    this.SupportDescriptiontxt.DataBindings.Clear();
                    this.SupportdatePicker.DataBindings.Clear();

                    this.SupportPersonnelIDtxt.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.supportTblBindingSource, "Operator", true));
                    this.SupportCallingPersontxt.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.supportTblBindingSource, "CallingPerson", true));
                    this.SupportCustomerProductIDtxt.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.supportTblBindingSource, "Product", true));
                    this.SupportIssuetxt.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.supportTblBindingSource, "Issue", true));
                    this.SupportServicetxt.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.supportTblBindingSource, "Service", true));
                    this.SupportResulttxt.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.supportTblBindingSource, "Description", true));
                    this.SupportDescriptiontxt.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.supportTblBindingSource, "Result", true));
                    this.SupportdatePicker.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.supportTblBindingSource, "Date", true));

我尝试了更好的方法。这就是我用DGV中所选行的值填充文本框的方法。

代码：

SupportPersonnelIDtxt.Text = dataGridView7.Rows[e.RowIndex].Cells[0].Value.ToString();

将文本框绑定到DGV并清除它？
