#Generic WPF Form Controls Library A WPF control library, provides a set of controls which can create edit form or query control based on target entity’s annotation attributes. It can work best with Entity framework code first design, see entity below:
public class User
{
[Key]
public int UserId { set; get; }
[StringLength(10)]
[Display(Name = "登录名")]
[Required(ErrorMessage="必填")]
[Index("username_index",IsUnique=true)]
public string Username { set; get; }
[StringLength(100)]
[Display(Name = "密码")]
[UIHint("password")]
[Required(ErrorMessage = "必填")]
public string Password { set; get; }
[StringLength(10)]
[Display(Name = "姓名")]
[Required(ErrorMessage = "必填")]
public string Name { set; get; }
[StringLength(50)]
[Display(Name = "身份证")]
[Required(ErrorMessage = "必填")]
[RegularExpression(@"^(^\d{15}$|^\d{18}$|^\d{17}(\d|X|x))$",ErrorMessage="格式不正确")]
public string IdentificationNumber { set; get; }
[StringLength(20)]
[Display(Name = "电话")]
[RegularExpression(@"^[0-9]*",ErrorMessage="格式不正确")]
[Required(ErrorMessage = "必填")]
public string PhoneNumber { set; get; }
[StringLength(50)]
[Display(Name = "公司")]
public string Company { set; get; }
[StringLength(50)]
[Display(Name = "部门")]
public string Department { set; get; }
[Display(Name = "权限", Description = "用户的访问权限")]
public PermissionGroup PermissionGroup { set; get; }
[Display(Name = "备忘")]
[StringLength(5000)]
public string Memo { set; get; }
}
public enum PermissionGroup
{
[Display(Name = "冻结", Description = "没有任何权限")]
Guest = 0,
[Display(Name = "普通用户", Description = "只有查询权限")]
User = 1,
[Display(Name = "仓库管理员", Description = "管理入库出库，查询")]
Operator = 2,
[Display(Name = "系统管理员", Description = "拥有所有权限")]
Admin = 3
}
Use Form control, it will create edit view below dynamically
Use Query Control, it will create view below dynamically
##Entity Annotation attribute sheet
| Attribute | Function |
|---|---|
| [Key] | Control will not generate input row for field with this attribute |
| [Editable(AllowEdit=false)] | Control will not generate input row for field with this attribute |
| [Display(Name = "filed display name")] | Set input row’s display name |
| [UIHint("password")] | Use password input row for target field |
| All validation attribute | Validate the target field before submit |
| [UIHint("")] | Reserved for extend input controls |
##Create Edit Form See sample code below:
public Control CallUpdateUserControl(User user, Action<User> updateCallback=null)
{
var formControl = FormControlHelper.CreateFormControl();
// **make sure Username is displayed**
formControl.DetermineFieldCreationCallback = (cx, s) =>
{
switch (cx.PropertyInfo.Name)
{
case "Username":
return true;
default:
return s;
}
};
// **replace password edit control**
// **Set Username field to readonly**
formControl.CreateControlCallback = (cx, c) =>
{
if (cx.ControlType == ControlType.Editable)
{
if (cx.PropertyInfo.Name == "Password")
{
return CreateResetPwdButton(user);
}
else if (cx.PropertyInfo.Name == "Username")
{
c.IsEnabled = false;
}
}
return c;
};
// **submit callback**
formControl.SubmitCallback = (d) =>
{
using (var dbcontext = new WarehouseContext())
{
// call EF to save entity
}
};
formControl.RenderForm(user, false);
// **customize submit button**
formControl.ConfirmButton.Content = "保存设置";
return formControl;
}
##Create Query Window Check file /src/WarehouseMgr/WarehouseOperation/QueryGoods.xaml
