DataBindingComplete被多次调用

问题描述

我在c＃中创建一个Windows应用程序，

我有1个Datagridview，在我设置它的DataSource之后，它应该有3行。

我已将2个事件Habdlers附加到Datagrdview

  void dgvProductList_RowsAdded（object sender，DataGridViewRowsAddedEventArgs e） < br> 
 {
 //这被称为4次
} 
 
 private void dgvProductList_DataBindingComplete（object sender，DataGridViewBindingCompleteEventArgs e）
 {
 //被叫2次。 
} 
  

为什么这会发生，我该如何解决？

感谢提前...

解决方案

例如如果您分配Datasource，然后添加3行 - > 4次事件触发

I am creating a windows application in c#,

I have 1 Datagridview and after I set it's DataSource it should have 3 Rows.

I have attached 2 Event Habdlers to the Datagrdview

void dgvProductList_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)<br>
{
     //this gets called 4 times
}

private void dgvProductList_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
    //gets called 2 times.
}

Why does this Happen and how would I fix it?

Thanks In Advance...

解决方案

From msdn online DataBindingComplete Event

E.g. If you are assigning Datasource, and then adding 3 rows --> 4 times event fired
