Question

每当我单击复选框并查看单元格值更改事件时，如果最初取消选中该复选框，则该值始终为false;如果最初选中该复选框，则该值始终为true ...

更新：因此，当我检查框时 - 然后细胞失去焦点，它会变回原来的状态 - 但不知道为什么???

为什么会这样，我该如何解决这个问题？

private void CellValueChanged(object sender, GridViewCellEventArgs e)
        {
//e.Value always false or true depending on original state
}

                AddDefaultEvents(user);

RadGridView中的复选框编辑器是一个永久编辑器，只有在更改当前单元格时才会更改单元格值。要在用户选中复选框时强制更改值，您需要订阅RadGridView的ValueChanged事件并调用EndEdit方法：

void radGridView1_ValueChanged(object sender, EventArgs e)
{
    if (radGridView1.CurrentColumn.Name == "MyCheckBoxColumnName")
    {
        radGridView1.EndEdit();
    }
}

RadGridView复选框控件始终为false
