我在 VB.net 中编程。我正在尝试通过针对我的数据库搜索电子邮件地址来填充 2 个 gridview 表。当用户单击搜索按钮时，我希望我的程序从文本框中获取值，根据我的数据库搜索电子邮件地址，然后在我的“ScrumMaster”表和“开发人员”表中显示用户配置文件。我不知道如何在一个“btnSearchEmail_Click”方法中实现所有这些。目前我拥有的代码是

 Protected Sub btnSearchEmail_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearchEmail.Click

End Sub


Protected Sub ScrumMastersDataSource_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LinqDataSourceSelectEventArgs) Handles ScrumMastersDataSource.Selecting
    Dim db As New AgileClassesDataContext()

    Dim enteredEmail = txtEnteredEmail.Text

    Dim scrumMasters = (From u In db.Users
                      Join ur In db.UserRoles On u.UserId Equals ur.UserId
                      Join r In db.Roles On ur.RoleId Equals r.RoleId
                      Where r.RoleId = 2 And u.Email = enteredEmail
                      Select u).Distinct

    e.Result = scrumMasters
End Sub


Protected Sub DevelopersDataSource_Selecting(sender As Object, e As System.Web.UI.WebControls.LinqDataSourceSelectEventArgs) Handles DevelopersDataSource.Selecting
    Dim db As New AgileClassesDataContext()

    Dim enteredEmail = txtEnteredEmail.Text

    Dim developers = (From u In db.Users
                      Join ur In db.UserRoles On u.UserId Equals ur.UserId
                      Join r In db.Roles On ur.RoleId Equals r.RoleId
                      Where r.RoleId = 3 And u.Email = enteredEmail
                      Select u).Distinct

    e.Result = developers
End Sub

如您所见，这里有 3 种方法。我想将“ScrumMastersDataSource_Selecting”和“DevelopersDataSource_Selecting”放在“btnSearchEmail_Click”事件中，以便在单击“btnSearchEmail”时它们都运行。由于电子邮件地址可能与开发人员和 Scrum Master 角色相关联，因此重复不是问题。任何的建议都受欢迎。我希望这个问题有意义

尝试这样的事情（这是 C#/VB.NET 的混合）：

private void RefreshGrids()
{
    ScrumMastersDataSource.DataSource = GetListScrum(txtEnteredEmail.Text);
    ScrumMastersDataSource.DataBind();
    DevelopersDataSource.DataSource = GetListDev(txtEnteredEmail.Text);
    DevelopersDataSource.DataBind();
}

Protected Sub btnSearchEmail_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearchEmail.Click

    RefreshGrids();

End Sub
