C＃ - 如何在消息框中显示textbox.text？ [英] C# - how do I display textbox.text inside a messagebox?

问题描述

我正在尝试在MessageBox中显示textBox的文本。根本没有错误消息。 TextBox的内容根本没有出现在MessageBox中（代码中的第一个MessageBox）。你能看看它并告诉我出了什么问题吗？对此，我真的非常感激。谢谢！最好的祝福。 :)



我的尝试：

I am trying to display the text of a textBox inside a MessageBox. There are no error messages at all. The contents of the TextBox simply don't appear in the MessageBox (first MessageBox in the code). Can you please take a look at it and tell me what's wrong? I really appreciate it. Thank you! Best regards. :)

What I have tried:

private void bindingNavigatorDeleteItem_Click(object sender, EventArgs e)
{
    if (MessageBox.Show("Tem certeza que deseja excluir o pagamento " + cod_caixaTextBox.Text, "Atenção", MessageBoxButtons.OKCancel) == System.Windows.Forms.DialogResult.OK)
    {
        this.caixaBindingSource.EndEdit();
        this.tableAdapterManager.UpdateAll(this.bremingtonBackEndDataSet);
        MessageBox.Show("Pagamento excluido com sucesso!", "Pronto ...", MessageBoxButtons.OK);
    }
    else
    {
        caixaBindingSource.CancelEdit();
        this.caixaTableAdapter.Fill(this.bremingtonBackEndDataSet.caixa);
    }
}

推荐答案

我发现问题是什么：TextBox内容的原因是什么MessageBox中没有显示的是因为当我单击BindingNavigatorDeleteItem时，它会删除记录而不进行确认，因此MessageBox无法显示TextBox.Text，因为它已被删除。现在我必须找到一种方法来在BindingNavigatorDeleteItem删除记录之前添加确认。有什么想法吗？

I found what the problems is: the reason why the contents of the TextBox are not displayed in the MessageBox is because when I click on the BindingNavigatorDeleteItem, it deletes the record without confirmation, thus the MessageBox can't display the TextBox.Text because it has been deleted. Now I have to find a way to add the confirmation BEFORE the BindingNavigatorDeleteItem deletes the record. Any ideas?

SUCCESS !!!我需要做的就是将绑定导航器的DeleteItem属性设置为NONE，这样我就可以手动处理事件了。

SUCCESS!!! All I needed to do was set the DeleteItem property of the binding navigator no NONE so I could handle the event manually.
