【问题描述】:
我有一个简单的自定义工作项控件,可以在 VS 2013 中完美运行。我最近在我的 Windows 10 机器上安装了 VS 2015,该控件引发如下错误:
TF400939:自定义控件类型“TimSheetsControl.WITimeSheetControl”未实现 IWorkItemControl 接口或针对不同版本的 Visual Studio 编译。
这令人沮丧,因为控件确实实现了 IWorkItemControl 接口。至少据我所知,编译到 Visual Studio 版本似乎也不是一回事。
我尝试创建一个非常简单的控件(只是屏幕上的一个 ComboBox)来进行一些测试,但我得到了完全相同的错误。
我想我有几个问题:
- 我应该再在 Visual Studio 中做这种类型的自定义控件吗?或者我应该创建 Web 控件来替换曾经在 Visual Studio 中完成的操作。
- 我做错了什么导致此操作失败?
我创建的非常简单的控制代码如下,如果这些信息有用,我很乐意回答有关我的环境的问题。
感谢您的时间和关注。
用户控制代码后面(WITimeSheetControl):
namespace TimSheetsControl
{
public partial class WITimeSheetControl : UserControl, IWorkItemControl
{
private object WorkItemDataSource;
protected IServiceProvider ServiceProvider = null;
public WITimeSheetControl()
{
InitializeComponent();
}
public StringDictionary Properties{get; set;}
public bool ReadOnly { get; set; }
public object WorkItemDatasource
{
get
{
return WorkItemDataSource;
}
set
{
WorkItemDataSource = value;
}
}
public string WorkItemFieldName { get; set; }
public event EventHandler AfterUpdateDatasource;
public event EventHandler BeforeUpdateDatasource;
public void Clear()
{
}
public void FlushToDatasource()
{
}
public void InvalidateDatasource()
{
if (string.IsNullOrEmpty(WorkItemFieldName))
{
throw new ArgumentNullException("The fieldname property for the WITimeSheetControl is not set.");
}
cmbPosition.SelectedIndex = -1;
}
public void SetSite(IServiceProvider serviceProvider)
{
ServiceProvider = serviceProvider;
}
}
}
用户控件设计器代码:
namespace TimSheetsControl
{
partial class WITimeSheetControl

protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Component Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.cmbPosition = new System.Windows.Forms.ComboBox();
this.SuspendLayout();
//

this.cmbPosition.DropDownWidth = 145;
this.cmbPosition.FormattingEnabled = true;
this.cmbPosition.Items.AddRange(new object[] {
"Business Analyst",
"Programmer"});
this.cmbPosition.Location = new System.Drawing.Point(139, 23);
this.cmbPosition.MaximumSize = new System.Drawing.Size(165, 0);
this.cmbPosition.Name = "cmbPosition";
this.cmbPosition.Size = new System.Drawing.Size(151, 21);
this.cmbPosition.TabIndex = 0;
//
// WITimeSheetControl
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.Controls.Add(this.cmbPosition);
this.Name = "WITimeSheetControl";
this.Size = new System.Drawing.Size(1219, 565);
this.ResumeLayout(false);
}
#endregion
