清除除一个以外的所有文本框。 [英] clear all textboxes except one.

问题描述

我的表单上有一个列表框和多个文本框。当选择列表框项目时，我能够从数据库检索数据到texboxes但是当在列表框中插入新项目时，我使用以下功能清除所有文本框... < br $>

I have a listbox and mulitiple textboxes on my form.When listbox item is selected i am able to retrieve data from database to texboxes But when new item is inserted in listbox i am using following function to clear all textboxs ...

private void ClearTextBoxes(Control.ControlCollection cc)
       {
           foreach (Control ctrl in cc)
           {
               TextBox tb = ctrl as TextBox;
               if (tb != null)
                   tb.Clear();
               else
                   ClearTextBoxes(ctrl.Controls);
           }
       }

我想要的是将selectitem名称（尚未存储在数据库中）放入文本框中，但由于此功能，文本框显示清晰..
