这是我的项目,我正在使用visual studio 2010,我的编码语言是vb。我是新手,可以说我还不太了解它。
我有一个登录页面,部门负责人输入他的详细信息(员工编号,员工姓名),选择他的部门并提交信息,以便以其他网络形式查看结果,即所有在其部门下的员工所有为公司工作的员工。
因为我不知道代码,所以我得到gridview中每个部门的所有员工,而不是从下拉列表中选择部门的员工。

请告诉我流程和代码,以及放在哪里,我对这一切都不是很熟悉。这是一种紧急情况。

您可以将所选项目文本存储在onw变量中,如下所示:
dim selText as string = DropDownList1.SelectedItem.Text
点击“提交”按钮,执行所需任务,然后将页面重定向到另一个页面以及部门名称。如下面的代码:
Response.Redirect("Page2.aspx?department=" + selText)
并在第二页上,即Page2.aspx,只需在查询字符串中接收此值,使用以下代码..无论是在页面加载还是在您需要的地方都需要。
If Request.QueryString("department") <> Nothing Then
dim departmt as string = Request.QueryString("department")
End If
在数据库查询中使用上述变量的值,并将相关数据提供给在上一个表单中选择的部门。
我希望它会对你有所帮助。 :)

您还可以在会话中保存所选项目文本。之后,您可以从项目的任何页面获取此值:
Session("department") = DropDownList1.SelectedItem.Text
您也可以直接在Page2上的SqlDataSource中使用此值:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString11 %>"
ProviderName="<%$ ConnectionStrings:ConnectionString11.ProviderName %>"
SelectCommand="SELECT * FROM [employee database] WHERE Department LIKE @depart">
<SelectParameters>
<asp:SessionParameter DefaultValue="%" Name="depart" SessionField="user"
Type="string" />
</SelectParameters>
</asp:SqlDataSource>
