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主键***
我已经建立了一个矩阵，该矩阵显示所有员工和所有课程.由于我有三门课程，每门课程需要三张桌子，因此我需要为每门课程提供一张桌子.我开发了此矩阵，以便在Repeater控件中使用GridView查看信息.另外，我再次开发了使用C#中的HTMLTable输入数据的方法.一切正常.我现在需要给每个组指定特定的颜色.例如，具有蓝色的Group#1和具有黄色的Group#2，依此类推.我现在正在用C#进行此操作.
**那么有人可以帮我解决这个问题吗?**
我在ASP.NET和C#中的代码如下:
ASP.NET:
I have the following database design:
> Employee Table: Username, name, Job... etc
>
> Course Table: CourseID, CourseName, GroupID
>
> Employee_Courses Table: EmployeeID, CourseID
>
> Group Table: GroupID, GroupName
***NOTE: The first attribute in each table is the primary key***
I have developed a matrix that shows all employees and all courses. Since I have three groups of courses three, I need to have one table for each group of courses. I developed this matrix to view the information using GridView inside a Repeater control. Also, I developed again for entering data using the HTMLTable in C#. Everything works fine. What I need now is to give each group specific color. For example, Group#1 with Blue color and Group#2 with Yellow color and so on. I am struggling now with doing this in C#.
**So could anyone please help me with this issue?**
My code in ASP.NET and C# is as following:
ASP.NET:
<asp:PlaceHolder ID="PlaceHolder1" runat="server" />
<%--This SqlDataSource is for retrieving the GroupID--%>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:testConnectionString %>"
SelectCommand="SELECT [ID] FROM [groups]"></asp:SqlDataSource>
<%--This SqlDataSource is for retrieving the information of the employees and the safety training coruses--%>
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:testConnectionString %>"
SelectCommandType="StoredProcedure" SelectCommand="kbiReport" FilterExpression="[DivisionName] like ''{0}%''">
<SelectParameters>
<asp:Parameter Name="GroupID"/>
</SelectParameters>
<FilterParameters>
<asp:ControlParameter ControlID="ddlDivision" Name="DivisionName"
PropertyName="SelectedValue" Type="String" />
</FilterParameters>
</asp:SqlDataSource>
<%--Filtering by Division--%>
<asp:SqlDataSource ID="sqlDataSourceDivision" runat="server"
ConnectionString="<%$ ConnectionStrings:testConnectionString %>"
SelectCommand="SELECT [DivisionName] FROM [Divisions]"></asp:SqlDataSource>
<asp:Button ID="updateButton" runat="server" OnClick="updateButton_Click" Text="Update" />
**注意:**组ID将从SqlDataSource1中检索，然后将在SqlDataSource2中使用
C#:
**NOTE:** GroupID will be retrived from SqlDataSource1, and then will be used in SqlDataSource2
C#:
protected void Page_Load(object sender, EventArgs e)
{
DataView dv2 = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty);
foreach (DataRowView group in dv2)
{
SqlDataSource2.SelectParameters[0].DefaultValue = group[0].ToString();
//create a new HtmlTable object
HtmlTable table = new HtmlTable();
DataView dv = (DataView)SqlDataSource2.Select(DataSourceSelectArguments.Empty);
int columns = dv.Table.Columns.Count;
int rows = dv.Count;
//table's formating-related properties
table.Border = 2;
table.CellPadding = 3;
table.CellSpacing = 3;
table.Width = "900px";
//to get the css style
table.Attributes["class"] = "mGrid";
//create a new HtmlTableRow and HtmlTableCell objects
HtmlTableRow row;
HtmlTableRow header = new HtmlTableRow();
HtmlTableCell cell;
//for adding the headers to the table
foreach (DataColumn column in dv.Table.Columns)
{
HtmlTableCell headerCell = new HtmlTableCell("th");
headerCell.InnerText = column.Caption;
//I need to specify the color for each group here
header.Cells.Add(headerCell);
}
table.Rows.Add(header);
//loop for adding rows to the table
foreach (DataRowView datarow in dv)
{
row = new HtmlTableRow();
row.BgColor = "yellow";
//loop for adding cells
for (int j = 0; j < columns; j++)
{
cell = new HtmlTableCell();
if (j < 4)
{
cell.InnerText = datarow[j].ToString();
}
else
{
CheckBox checkbox = new CheckBox();
int checkBoxColumns = dv.Table.Columns.Count - 5;
string fieldvalue = datarow[j].ToString();
string yes = fieldvalue.Split(new string[] { ", " }, StringSplitOptions.RemoveEmptyEntries)[1];
string courseid = fieldvalue.Split(new string[] { ", " }, StringSplitOptions.RemoveEmptyEntries)[0];
checkbox.ID = row.Cells[3].InnerText + "," + courseid.Trim();
checkbox.Checked = yes.Equals("Yes");
cell.Controls.Add(checkbox);
}
//add the cell to the current row
row.Cells.Add(cell);
}
//add the row to the table
table.Rows.Add(row);
}
//add the table to the page
PlaceHolder1.Controls.Add(table);
}
}
