推荐答案

单击DataGridView的复选框时，它将处于脏状态，而单击另一个单元格或行时，数据将坚定的.在您的情况下，当您单击复选框并且不单击其他位置时，CurrentCell将处于脏状态.如下所示处理以下事件以提交数据

When a check box of DataGridView is clicked, it will be in dirty state and when another cell or row is clicked the data will be committed. In your case when you click the check box and do not click elsewhere then the CurrentCell will be in dirty state. Handle the following event as shown below to commit the data

void dataGridView1_CurrentCellDirtyStateChanged(object sender,
EventArgs e)
{
    //replace ColumnIndex == 1 in the following code with column index of your check box column
    if (dataGridView1.CurrentCell.ColumnIndex== 1 && dataGridView1.IsCurrentCellDirty)
    {
    	dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
    }
}

您好，朋友...


正如您所说的，您看不到datagridview.right的更新值.

所以您可以尝试一下，希望它能解决您的问题...


在复选框的末尾或任何会影响gridview单元格值的事件中，您需要在逻辑代码的末尾再添加一行，就像这样...

Hello freind...


As you say you cant see the updated value to your datagridview.right...

so you can try this i hope it will solve your problem...


at the end of checkbox or any event which will affect your gridview cell value you need to put one more line at the end of your logical code like this...

DataGridView1.Refresh();

我希望它对您有用....

i hope it will work for you....
