DataGridViewCheckBoxColumn:如何在属性更改而不是验证时更新绑定数据源

问题描述

我已经绑定了一个 BindingList 作为 DataGridView 的数据源；TSource 属性之一绑定到 DataGridViewCheckBoxColumn，但数据源不是在单击复选框时更新，而是在复选框本身失去焦点时更新.

I've got a BindingList binded as the data source of a DataGridView; one of the TSource properties is binded to a DataGridViewCheckBoxColumn, but the data source is updated not when a click on the checkbox occurs, but when the focus on the checkbox itself is lost.

我知道当 DataSourceUpdateMode 为OnValidation"而不是OnPropertyChanged"时，标准 WindowsForms 绑定上会发生类似的事情，但是如何使用 DataGridViewCheckBoxColumn 获得相同的结果?

I know that something similar happens on a standard WindowsForms binding when the DataSourceUpdateMode is "OnValidation" instead of "OnPropertyChanged", but how can I have the same results with a DataGridViewCheckBoxColumn?

列定义如下:

            DataGridViewCheckBoxColumn column = new DataGridViewCheckBoxColumn();
            column.DataPropertyName = "MyProperty";
            column.HeaderText = "Title";

            dataGridView.Columns.Add(column);

推荐答案

您可以通过处理 DataGridView 的 CurrentCellDirtyStateChanged 事件来做到这一点.

You can do this by handling the CurrentCellDirtyStateChanged event of the DataGridView.

void dataGridView1_CurrentCellDirtyStateChanged(object sender,EventArgs e)
{
    if (dataGridView1.IsCurrentCellDirty)
    {
        dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
    }
}
