在单击按钮的窗体上运行所有验证事件 [英] Run all Validating events on the Form on button click
问题描述
我有一个带有一些文本框和组合框的小表格，每个框都有自己的验证事件，当用户移至下一个框而不输入任何内容时，它们仅填充默认值1或0(取决于框)我也想在用户直接单击提交"按钮时运行所有验证.
I have a little form with some text boxes and combo boxes, each with their own validating event which just fills the default value either 1 or 0 depending on the box when the user moves on to the next box without entering anything, however i also want to run all the validations when the user just clicks on the submit button directly.
private void Validating_Zero(object sender, CancelEventArgs e)
{
if (((TextBox_Pro)sender).Text == "")
{
((TextBox_Pro)sender).Text = "0";
}
}
private void Validating_One(object sender, CancelEventArgs e)
{
if (((TextBox_Pro)sender).Text == "")
{
((TextBox_Pro)sender).Text = "1";
}
}
private void Start_Validating(object sender, CancelEventArgs e)
{
}
推荐答案
调用 ValidateChildren() 方法，使该表单的所有子控件验证其数据.
Calling ValidateChildren() method of the form, cause all of the child controls of the form to validate their data.
You can also use the the other overload of the method which accepts a validation constraint, ValidateChildren(ValidationConstraints) to limit the validation to immediate child controls, enabled controls, tab stop controls, selectable controls, visible controls or all control.
