如何创建复选框运行时

问题描述

大家好我在运行时在gridview中创建复选框。

但我遇到的一个问题是我使用复选框，当我检查复选框然后datagridview填充数据并自动创建一个复选框行。

问题是

当我取消选中chekbox然后datagrid视图数据源是空的，当我再次选中复选框时，它会创建两个复选框，每行内有一行网格视图....

当我再次取消选中复选框并再次选中复选框，然后在网格视图中创建三个复选框任何一个帮助我如何停止多重检查在网格视图中创建的框。

---------------------------------- -------------------------------------------

我只想要一个包含所有行的复选框



我试试这个代码

当复选框检查状态改变时运行此代码



我尝试过：

私人无效isacti veOffercheckBox_CheckedChanged（object sender，EventArgs e）
 {
 if（isactiveOffercheckBox.Checked == true）
 {
 OfferdataGridView.DataSource = null; 
 OfferdataGridView.DataSource = GetofferfromDb（）; 
 DataGridViewCheckBoxColumn chekbox = new DataGridViewCheckBoxColumn（）; 
 chekbox.HeaderText =chekbox; 
 chekbox.Name =chekbox; 
 OfferdataGridView.Columns.Add（chekbox）; 
 OfferdataGridView.Enabled = true; 
 OfferdataGridView.Height = 146; 
} 
其他
 {
 OfferdataGridView.DataSource = null; 
 OfferdataGridView.Enabled = false; 
} 
}
