如何用三组课程(或多个表)来开发一个表? [英] How to develop one table with three groups of courses (or tables)?
本文介绍了如何用三组课程(或多个表)来开发一个表?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我具有以下数据库设计:
>员工表:用户名，名称，工作...等
>
>课程表:CourseID，CoursName，GroupID
>
> Employee_Courses表:EmployeeID，CourseID
>
>群组表:GroupID，GroupName
***注意:每个表中的第一个属性是外键***
我有三组课程，现在我需要开发一个培训矩阵，该矩阵显示所有员工和所有课程，并给每组课程指定特定的颜色，例如:蓝色代表第1组，黄色代表第2组，橙色代表第#组3.我做了一个StoredProcedure，它负责从数据库中检索数据.另外，我可以使用以下方法设计矩阵:Repeater，并在其中放入一个带有HiddenField的GridView，用于检索每个组的ID.这样，我得到了三个表或GridViews.每组课程的表格.
我现在想要的是生成一个包含所有这些组的表，并为每组课程赋予其颜色，那么该怎么做呢?
为了简单地说明我所做的事情，这是我在ASP.NET和C#中的代码:
ASP.NET:
I have the following database design:
> Employee Table: Username, Name, Job ...etc
>
> Courses Table: CourseID, CourseName, GroupID
>
> Employee_Courses Table: EmployeeID, CourseID
>
> Group Table: GroupID, GroupName
***NOTE: the first attribute in each table is the foreign key***
I have three groups of courses and I need now to develop a training matrix that shows all employees and all courses with giving each group of courses a specific color such as: Blue for Group#1, Yellow for Group#2 and Orange for Group#3. I made a StoredProcedure that takes care for retrieving the data from the Database. Also, I could be able to design the matrix by using the following method: Repeater and I put inside it one GridView with a HiddenField for retrieving the ID for each group. By doing this, I got three tables or GridViews; Table for each group of courses.
What I want now is to generate one table that contains all of theses groups with giving each group of courses its color, so how to do that?
To give a simple idea about what I did, this is my code in ASP.NET and C#:
ASP.NET:
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:HiddenField ID="HiddenField1" runat="server" Value=''<%# Eval("GroupID")%>'' />
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:testConnectionString %>"
SelectCommandType="StoredProcedure" SelectCommand="kbiReport"
FilterExpression="[Division] like ''{0}%''">
<FilterParameters>
<asp:ControlParameter ControlID="ddlDivision" Name="DivisionShortcut"
PropertyName="SelectedValue" Type="String" />
</FilterParameters>
<SelectParameters>
<%--ControlParameter is linked to the HiddenField above to generate different GridView based on different values
of GroupID--%>
<asp:ControlParameter ControlID="HiddenField1" Name="GroupID" PropertyName="Value" />
</SelectParameters>
</asp:SqlDataSource>
<div class="grid_4">
<asp:GridView ID="GridView1" runat="server"
AllowSorting="True"
CellPadding="3"
DataSourceID="SqlDataSource1"
ClientIDMode="Static" CssClass="myTable04"
AlternatingRowStyle-CssClass="alt"
RowStyle-HorizontalAlign="Center"
OnRowDataBound="GridView1_RowDataBound" OnPreRender="GridView1_PreRender">
<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
<HeaderStyle Font-Bold = "true" ForeColor="Black" />
<Columns>
<%--<asp:CommandField ShowSelectButton="True" />--%>
</Columns>
<EditRowStyle BackColor="#999999" />
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
<RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
<SortedAscendingCellStyle BackColor="#E9E7E2" />
<SortedAscendingHeaderStyle BackColor="#506C8C" />
<SortedDescendingCellStyle BackColor="#FFFDF8" />
<SortedDescendingHeaderStyle BackColor="#6F8DAE" />
</asp:GridView>
</div>
<br /> <br /><br /> <br /><br /> <br /><br /> <br />
</ItemTemplate>
</asp:Repeater>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:testConnectionString %>"
SelectCommand="SELECT DISTINCT GroupID FROM courses">
</asp:SqlDataSource>

}
//This for deleting the showing the first column (Division) when the Filter value is ALL

{
e.Row.Cells[0].Visible = false;
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
foreach (TableCell c in e.Row.Cells)
{
// Check if the cell vlaue = Yes
// if it is Yes, the cell will be colored with Light Green
if (c.Text.Contains(", Yes"))
{
c.BackColor = System.Drawing.Color.LightGreen;
c.Text = "•";
}
else if (c.Text.Contains(", NO"))
{
c.Text = "";
}
}
}
// The following is for changing the color of headers in each GridView based on the value of the HiddenFild

protected void GridView1_PreRender(object sender, EventArgs e)
{
var gv = sender as GridView;
if (gv.Rows.Count > 0)
{
gv.UseAccessibleHeader = true;
gv.HeaderRow.TableSection = TableRowSection.TableHeader;

为创建视图会生成一个包含所有这些组的表，并为每组课程赋予其颜色
