RadGridView复选框控件始终为false

本文关键字：false 复选框 控件 RadGridView | 更新日期: 2023-09-27 18:20:24

每当我单击复选框并查看单元格值更改事件时，如果最初未选中复选框，则该值始终为false，如果最初选中复选框则始终为true。。。

更新：所以，当我选中这个框时——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？我该如何避开？

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

更新：

填充GridView

public void PopulateEvents(User user)
        {
            if (user.EventSubscriptions.Count < 1)
                AddDefaultEvents(user);
            var query = user.EventSubscriptions.Join(sp.Events, r => r.EventId, p => p.EventId, (r, p) =>
                new { r.UserId, r.EventSubscriptionId, p.EventType, p.EventAction, r.IsAlert, r.IsEmail, r.AlertLevel })
                .Where(pr => pr.UserId == user.ID);
            BindingSource temp = new BindingSource() { DataSource = query };
            RGVAlerts.DataSource = temp; 
            //RGVAlerts.DataSource = query;
            foreach (var column in RGVAlerts.Columns)
            {
                switch (column.HeaderText)
                {
                    case "EventType":

RadGridView复选框控件始终为false

RadGridView中的复选框编辑器是一个永久编辑器，只有当您更改当前单元格时，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();
    }
}
