推荐答案

创建一个新的 DataTable 并绑定数据（列和行）从那些 ListBoxes 获取数据。



你需要实现这个逻辑。自己尝试一下。如果您在编码时遇到任何特定问题，请回到此处并添加另一个解释问题的问题，以便我们提供帮助。



继续编码。 ：）

Create a new DataTable and bind data (Columns and Rows) to that by taking data from those ListBoxes.

You need to implement this logic. Try something on your own. If you face any specific problem while coding, then come back here and add another question explaining the problem, so that we can help.

Keep coding. :)

请参阅以下链接：

在TemplateField的ItemTemplate中绑定DropDownList [ ^ ]

绑定下拉列表和列表框 [ ^ ]

将列表框值绑定到gridview [ ^ ]



这可能会有所帮助。

Refer below links:
Bind DropDownList in ItemTemplate of TemplateField[^]
Binding dropdownlist and listbox [^]
Bind the listbox values into gridview[^]

This may help.

试试这样..

Try like this..

<form id="form1" runat="server">
    <asp:ListBox ID="ListBox1" runat="server">
        <asp:ListItem Text="Ram" />
        <asp:ListItem Text="Suresh" />
        <asp:ListItem Text="Rajesh" />
    </asp:ListBox>
    <asp:ListBox ID="ListBox2" runat="server">
        <asp:ListItem Text="AFF" />
        <asp:ListItem Text="MFA" />
        <asp:ListItem Text="EFA" />
    </asp:ListBox>
    <asp:GridView ID="gridView" runat="server" AutoGenerateColumns="false">
        <Columns>
            <asp:BoundField HeaderText="Name" DataField="Name" />
            <asp:BoundField HeaderText="Branch" DataField="Branch" />
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:DropDownList ID="ddl" DataSource='<%# Bind("ddlsoruce") %>'   runat="server">
                    </asp:DropDownList>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
    </form>

public partial class WebForm2 : System.Web.UI.Page
   {



       protected void Page_Load(object sender, EventArgs e)
       {
           if (!Page.IsPostBack)
           {
               List<Entity> lstSoruce = new List<Entity>();
               if (ListBox1.Items.Count == ListBox2.Items.Count)
               {
                   for (int i = 0; i < ListBox1.Items.Count; i++)
                   {
                       lstSoruce.Add(new Entity()
                       {
                           Name = ListBox1.Items[i].Text,
                           Branch = ListBox2.Items[i].Text,
                           ddlsoruce = ListBox1.Items.OfType<ListItem>().Select(k => k.Text).ToArray()
                       });


                   }
               }

               gridView.DataSource = lstSoruce;
               gridView.DataBind();



           }
       }

       class Entity
       {
           public string Name { get; set; }
           public string Branch { get; set; }
           public string[] ddlsoruce { get; set; }
       }




   }
