将文本框绑定到 DGV 并清除它？

Question

我检查了以下链接中的问题： This causes two bindings in the collection to bind to the same property. Parameter name: binding error in c#?

我遵循了给定的答案。错误消失了，但出现了新问题：

有一个 DGV，当我单击它的单元格时，一些文本框会绑定到选定的行。当我点击其他行之后，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));

我尝试了一个更好的方法。这就是我用 DGV 中所选行的值填充文本框的方式。

代码：

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