if to clear a text box is txtfname.text = "" then how about the combobox and the datetimepicker in vb.net?

cboPackage.items.clear it works but how to make the items in combo ox fill again.

推荐答案

组合框有几种.你在说哪一个?

我将从ComboBox.SelectedItem = null或类似的内容开始.想象一下，您可以使用DateTimePicker做类似的事情.当然，您可以通过快速的Google搜索找到所有答案.

There are several kinds of comboboxes. Which one are you talking about?

I would start with ComboBox.SelectedItem = null or something like that. I Imagine you can do something similar with the DateTimePicker. Of course, you could probably find all your answers with a quick google search.

组合框-objCombo.items.Clear()
日期选择器-请参见此处 [

Combobox - objCombo.items.Clear()
Datepicker - see here[^].

如果不是数据绑定控件，请调用ComboBox1.Items.Clear组合框
我不确定Datetimepicker是否具有这样的属性.也许您可以设置选定的日期而不是清除它.

If it is not a databound control call ComboBox1.Items.Clear for Combobox
I am not sure whether Datetimepicker has such a property. May be you can set the selected date instead of clearing it.
