DataGridView SelectionChanged事件被触发3次 [英] DataGridView SelectionChanged event fired 3 times

问题描述

您好，我在使用datagridview时遇到了一些问题。
所以这样...
我有这个代码：

private void frmOwners_Load（object sender，System.EventArgs e ）








完成后，还有2个SelectionChanged事件被激活



void void FillGrid（）
{
DataTable myDt = new DataTable（）;

myDt = DBEngine.GetAllRecords（）; //它是我自己获取数据的方法...

myDt.Columns [0] .Column.ColumnMapping = MappingType.Hidden;
myDt.Columns .Column.ColumnMapping = MappingType.Hidden;
myDt.Columns [7] .Column.ColumnMapping = MappingType.Hidden ;
myDataGrid.DataSource = myDt; //这会触发第一个selectionChanged方法...
}

void void myDataGrid_SelectionChanged（object sender，EventArgs e）
{
//这里是一些代码，但它被触发了3次



代码中的最后一行触发了selectionchanged方法，但是，它被逐个激发了3次...
有谁知道为什么???
是不是因为3列映射

Hi there,I've some problem using datagridview..
So like this...
I've this code:

private void frmOwners_Load(object sender, System.EventArgs e)
{
this.FillGrid();
//after this is done, there are fired 2 more SelectionChanged events
}

private void FillGrid()
{
DataTable myDt = new DataTable();

myDt = DBEngine.GetAllRecords(); //its my own method for getting data...

myDt.Columns[0].Column.ColumnMapping = MappingType.Hidden;
myDt.Columns.Column.ColumnMapping = MappingType.Hidden;
myDt.Columns[7].Column.ColumnMapping = MappingType.Hidden;
myDataGrid.DataSource = myDt; //This fires the first selectionChanged method...
}

private void myDataGrid_SelectionChanged(object sender, EventArgs e)
{
//here is some code, but it's fired 3 times
}

The last row from code fires the selectionchanged method, but, it's fired 3times one by one...
Does anyone know why???
Is it because the 3 columnmappings?

hi metaller

我已经尝试了你的代码，它运行正常。我不知道代码中的最后一行，哪行代码。你能准确提供吗。

I've tried your code, it works fine. I don't know your last row from code,  which line code. Can you provide it exactly.

谢谢。
