如何使用C＃2010中的删除按钮删除无界DataGridView中的选定行和整行？ [英] How to Delete selected rows and Entire rows in a Unbounded DataGridView using a Delete Button in C# 2010?

问题描述

在我的项目中我正在使用无界DataGridView。其中我使用标题复选框将第一行作为CheckBoxColumn。我提供了我的最终用户在DataGridView中选择单行或多行或整行，并且可以在需要时删除它。但真正的问题是，当我选择所有行并单击删除时，它会删除整行，而当我选择一行时，它会执行相同的操作。



以下是我的删除按钮代码。

In My Project I''m Using a Unbounded DataGridView . In Which I made First Row as CheckBoxColumn With Header Check Box . I Provided My End User to select a single row or multiple row or Entire rows in DataGridView and can delete it if they need it . But the real Problem is When I Select all rows and click delete it deletes Entire rows and while i select a single row it performs the same action.

Below is my delete Button code .

private void BtnDcDelete_Click(object sender, EventArgs e)
    {
        do
        {
            foreach (DataGridViewRow row in dataGridViewEx1.Rows)
            {
                try
                {
                    dataGridViewEx1.Rows.Remove(row);
                }
                catch (Exception) { }
            }
        } while (dataGridViewEx1.Rows.Count > 1);
    }

推荐答案

如果您只想删除选定的行，则需要使用SelectedRows属性：

If you want to delete just the selected rows, then you need to use the SelectedRows property:

foreach (DataGridViewRow row in myDataGridView.SelectedRows)
    {
    myDataGridView.Rows.Remove(row);
    }
