问题描述
我有问题。什么是C#Windows应用程序相当于UpdateSourceTrigger?
公共静态无效绑定(组合框中巴,ComboVAlidationRule VLD)
{
结合bndControl =新的绑定(的DataBind);
bndControl.Source = VLD;
bndControl.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
bndControl.ValidationRules.Add(VLD);
cmb.SetBinding(ComboBox.SelectedItemProperty,bndControl);
}
解决方案
Binding.DataSourceUpdateMode
是你要找的东西。
使用System.Windows.Forms的;// ... 约束力181 =新的绑定(文本,this.personBindingSource,姓名);
binding.DataSourceUpdateMode = DataSourceUpdateMode.OnPropertyChanged; this.nameTextBox.DataBindings.Add(绑定);
I have question. what is equivalent UpdateSourceTrigger in C# windows application?
public static void Bind(ComboBox cmb, ComboVAlidationRule vld)
{
Binding bndControl = new Binding("DataBind");
bndControl.Source = vld;
bndControl.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
bndControl.ValidationRules.Add(vld);
cmb.SetBinding(ComboBox.SelectedItemProperty, bndControl);
}
解决方案
Binding.DataSourceUpdateMode
is what you're looking for.
using System.Windows.Forms;
// ...
Binding binding = new Binding("Text", this.personBindingSource, "Name");
binding.DataSourceUpdateMode = DataSourceUpdateMode.OnPropertyChanged;
this.nameTextBox.DataBindings.Add(binding);
