这是代码.单击保存按钮时，组合框至少运行 3 次

this is the code. While clicking save button the combo box runs minimum 3 times

保存代码是

Me.validate
Me.tbl_Table1.bindingsource.EndEdit()
Me.tbl_table1tableadapter.UpdateAll(Me.Dataset1)

推荐答案

属性的赋值顺序必须是这样的.

DCNoComboBox.ValueMember = "ID"
DCNoComboBox.DataSource = Me.TableBindingSource
