i想要输出如下;
学院名称1 2 3 4 5
Ram dropdownlist1 dropdownlist2 dropdownlist3 dropdownlist4 dropdownlist5
Sam dropdownlist1 dropdownlist2 dropdownlist3 dropdownlist4 dropdownlist5
为什么我在asp.net中使用c＃。
解决方案
DataSource 包含两行，则 GridView 和其他所有将显示两行也会出现行中的DropDownLists 。
这意味着 GridView 行是只是 DataSource 中存在的行的副本。
您可以在这样的itemtemplate中设置下拉菜单
< asp：gridview id = gv1 runat = server xmlns： asp = ＃unknown >
< 列 >
< asp：templatefield headertext = 第1列 >
< itemtemplate >
< < span class =code-leadattribute> asp：dropdownlist id = ddl1 runat = 服务器 >
< asp：listitem value = 4 text = 优秀 > < / asp：listitem >
< asp：listitem value = 1 text = 好 > < / asp：listitem >
< asp：listitem 值 = 2 text = 公平 < span class =code-keyword>> < / asp：listitem < span class =code-keyword>>
< asp：listitem value = 3 text = 差 > < / asp：listitem >
< / asp：dropdownlist >
< / itemtemplate >
< / asp：templatefield >
< asp：templatefield < span class =code-attribute> headertext = 第2列 >
< itemtemplate >
< asp：dropdownlist id = ddl2 runat = 服务器 >
< asp：listitem value = 4 text = 优秀 < span class =code-keyword>> < / asp：listitem < span class =code-keyword>>
< asp：listitem value = 1 text = 好 > < / asp：listitem >
< asp：listitem value = 2 text = < span class =code-keyword>合格 > < / asp：listitem >
< asp：listitem value = 3 文本 = 差 > < / asp：listitem >
< / asp：dropdownlist < span class =code-keyword>>
< / itemtemplate >
< / asp： templatefield >
< / columns >
< / asp：gridview >
Adding dropdownlist in gridview in asp.net using C#.

<asp:GridView ID="gvfaculty" runat="server" BackColor="LightGoldenrodYellow" BorderColor="Tan"
BorderWidth="1px" CellPadding="2" ForeColor="Black" GridLines="None" Height="124px"
Width="91px" AutoGenerateEditButton="True" AutoGenerateColumns="False">
<alternatingrowstyle backcolor="PaleGoldenrod" />

<pagerstyle backcolor="PaleGoldenrod" forecolor="DarkSlateBlue" horizontalalign="Center" />
<SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" />
<sortedascendingcellstyle backcolor="#FAFAE7" />
<sortedascendingheaderstyle backcolor="#DAC09E" />
<sorteddescendingcellstyle backcolor="#E1DB9C" />
<sorteddescendingheaderstyle backcolor="#C2A47B" />
<columns>
<asp:TemplateField HeaderText ="Faculty Name">
<asp:TemplateField HeaderText = "1">
<itemtemplate>
<asp:DropDownList id="Rating1" runat="server">

Sam dropdownlist1 dropdownlist2 dropdownlist3 dropdownlist4 dropdownlist5
for that how can i do in asp.net using c#.
解决方案
If yourDataSourcecontains two rows, then two rows will show onGridViewand all otherDropDownListsin the Row will also appear.
That meansGridViewrows are just a replica of the rows present in yourDataSource.
You can set your dropdowns in an itemtemplate like this
<asp:gridview id="gv1" runat="server" xmlns:asp="#unknown"> <columns> <asp:templatefield headertext="Column 1"> <itemtemplate> <asp:dropdownlist id="ddl1" runat="server"> <asp:listitem value="4" text="Excellent"></asp:listitem> <asp:listitem value="1" text="Good"></asp:listitem> <asp:listitem value="2" text="Fair"></asp:listitem> <asp:listitem value="3" text="Poor"></asp:listitem> </asp:dropdownlist> </itemtemplate> </asp:templatefield> <asp:templatefield headertext="Column 2"> <itemtemplate> <asp:dropdownlist id="ddl2" runat="server"> <asp:listitem value="4" text="Excellent"></asp:listitem> <asp:listitem value="1" text="Good"></asp:listitem> <asp:listitem value="2" text="Fair"></asp:listitem> <asp:listitem value="3" text="Poor"></asp:listitem> </asp:dropdownlist> </itemtemplate> </asp:templatefield> </columns> </asp:gridview>
