如何使用文本框过滤datagridview并在C＃中单击按钮？

我找到了一个解决方案但我无法弄清楚最终的代码。有人可以帮帮我吗？我想在单击没有数据库的按钮后按TextBox值过滤我的dataridView。所以一个非常简单的过滤器。



谢谢！



我的尝试：

I have found a solution but I can't figure out the final code. Anybody please can help me out? I want to filter my dataridView by TextBox value after clicking on the button without database. So a very simple Filter.

Thank you!

What I have tried:

private void FilterButton_Click(object sender, EventArgs e)
{
    DataTable dt = ((DataTable)DataGridView2.DataSource);
    foreach (DataGridViewRow row in DataGridView2.Rows)
    {
        // Test if the first column of the current row equals
        // the value in the text box
        if ((String)row.Cells["Month"].Value == birthdayMonth.Text)
        {
            // we have a match
            row.Selected = true;
        }
        else
        {
            row.Selected = false;

        }
    }
}
