以前学习ASP.NET MVC时，学习与应用，操作过数据显示，添加，编辑，更新和删除等功能。
很多方法是相通的，看自己是怎样来进行方便，快捷，高效率。
今天Insus.NET写的练习，是直接对绑定在Table的数据进行更新，删除。
在项目中，创建一个实体，也就是说，对数据库时行通信，对数据进行操作：
public IEnumerable<ToolLocation> GetAllToolLocations()
{
sp.ConnectionString = DB.ConnectionString;
sp.Parameters = null;
sp.ProcedureName = "usp_ToolLocation_GetAll";
DataTable dt = sp.ExecuteDataSet().Tables[0];
return dt.ToList<ToolLocation>();
}
public void Update(ToolLocation tl)
{
List<Parameter> param = new List<Parameter>() {
new Parameter("@ToolLocation_nbr", SqlDbType.SmallInt, 2, tl.ToolLocation_nbr),
new Parameter("@LocationName",SqlDbType.NVarChar,-1,tl.LocationName),
new Parameter("@Description",SqlDbType.NVarChar,-1,tl.Description),
new Parameter("@IsActive",SqlDbType.Bit,1,tl.IsActive)
};
sp.ConnectionString = DB.ConnectionString;
sp.Parameters = param;
sp.ProcedureName = "usp_ToolLocation_Update";
sp.Execute();
}
public void Delete(ToolLocation tl)
{
List<Parameter> param = new List<Parameter>() {
new Parameter("@ToolLocation_nbr", SqlDbType.SmallInt, 2, tl.ToolLocation_nbr)
};
sp.ConnectionString = DB.ConnectionString;
sp.Parameters = param;
sp.ProcedureName = "usp_ToolLocation_Delete";
sp.Execute();
}
创建视图，并绑定数据：
@using Insus.NET.Models;
@model IEnumerable<ToolLocation>
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Edit</title>
<link href="~/Content/css/table.css" rel="stylesheet" />
<script class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original="~/Scripts/jquery-2.2.1.js"></script>
</head>
<body>
<div>
<table>
<tr>
<td>ToolLocation_nbr</td>
<td>LocationName</td>
<td>Description</td>
<td>IsActive</td>
<td></td>
</tr>
@foreach (var tl in Model)
{
<tr>
<td>@tl.ToolLocation_nbr<input id="Hidden1" type="hidden" value="@tl.ToolLocation_nbr" /></td>
<td>@Html.TextBox("LocationName", tl.LocationName)</td>
<td>@Html.TextBox("Description", tl.Description) </td>
<td>@Html.CheckBox("IsActive", tl.IsActive)</td>
<td>
<input class="Update" type="button" title="Update" value="Update" />
</td>
</tr>
}
</table>
</div>
</body>
</html>对数据进行更新的功能，下面的实现，是对Table内的数据删除。
@using Insus.NET.Models;
@model IEnumerable<ToolLocation>
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Delete</title>
<link href="~/Content/css/table.css" rel="stylesheet" />
<script class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original="~/Scripts/jquery-2.2.1.js"></script>
</head>
<body>
<div>
<table>
<tr>
<td>ToolLocation_nbr</td>
<td>LocationName</td>
<td>Description</td>
<td>IsActive</td>
<td></td>
</tr>
@foreach (var tl in Model)
{
<tr>
<td>@tl.ToolLocation_nbr<input id="Hidden1" type="hidden" value="@tl.ToolLocation_nbr" /></td>
<td>@tl.LocationName</td>
<td>@tl.Description</td>
<td>@Html.CheckBox("IsActive", tl.IsActive, new { disabled = "disabled" })</td>
<td>
<input class="Delete" type="button" title="Delete" value="Delete" />
</td>
</tr>
}
</table>
</div>
</body>
</html>
