DataGridViewCheckBoxCell如何当窗体加载过程中设置为显示检查 [英] DataGridViewCheckBoxCell how to show checked when set during form load

问题描述

我有一个DataGridView加载数据从数据表，连同DataGridViewCheckBoxCells的绑定列。都在DataGridView的行与值的单独的数据表相比，用户已保存，并且，如果有一个匹配，该行的复选框应该检查

I have a DataGridView that loads data from a DataTable, along with an unbound column of DataGridViewCheckBoxCells. The rows in the DataGridView are compared with a separate DataTable with values the user has saved, and if there is a match, the checkbox for that row should check.

下面是code的比较值，并将复选框价值为true：

Here is the code that compares the values and sets the checkbox value to 'true':

foreach (int j in selectedObjectives)
{
    foreach (DataGridViewRow r in dgvObjectives.Rows)
    {
        if (j == Convert.ToInt32(r.Cells["ObjectiveID"].Value))
        {
            dgvObjectives.CurrentCell = r.Cells["Select"];      
            ((DataGridViewCheckBoxCell)r.Cells["Select"]).Value = true;
            //dgvObjectives.InvalidateCell(r.Cells["Select"]);
            //dgvObjectives.EndEdit();
            //dgvObjectives.CommitEdit(DataGridViewDataErrorContexts.Commit);

        }
        if (Convert.ToInt32(r.Cells["ObjectiveID"].Value) == selectedIndex)
        {
            r.Selected = true;
        }
    }
}

当我调用该方法的形式负载私人无效WQMDrill_Load（对象发件人，EventArgs五），该值是否设置正确时执行该操作，但复选框做不检查。但是，当窗体加载完成后调用，code完美的作品。不幸的是我，我绝对需要为这些在加载过程检查。

When I call the method to perform this action during the form load private void WQMDrill_Load(object sender, EventArgs e), the values are set correctly, but the checkboxes do not check. However, when called after the form is finished loading, the code works perfectly. Unfortunately for me, I absolutely need for these to check during the load process.

我希望我很清楚我的问题，在这个问题上的任何帮助将不胜AP preciated。正如你所看到的，我已经试过单独的单元格，以及整个的DataGridView控制无效。我也有

I hope I was clear with my issue, any help on this matter would be greatly appreciated. As you can see, I have tried to invalidate the cell alone, as well as the entire DataGridView control. I also have

private void dgvObjectives_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
    if (this.dgvObjectives.CurrentCell.ColumnIndex == 0)
    {
        this.dgvObjectives.CommitEdit(DataGridViewDataErrorContexts.Commit);
    }
}

这不会在这段时间火。谢谢你。

That doesn't fire during this time. Thank you.

推荐答案

您可以把您的复选框的选择和更新逻辑在DataBindingComplete事件处理程序，将显示给用户的FormLoad之后，但任何在此之前火。

You can put your checkbox selection and update logic in the DataBindingComplete eventhandler, this fires after the FormLoad but before anything is displayed to the user.
