GridView使用數據庫實體篩選和篩選器

我是新來的數據庫模型，我正在嘗試篩選器輸入文本框時的gridView。GridView使用數據庫實體篩選和篩選器

我想通過一個文本框與文本框ID爲txtPatientName過濾我的網格視圖。有人可以幫我弄這個嗎？

提前致謝！我只需要簡單介紹一下如何做到這一點。

你想要在客戶端或服務器端完成此搜索嗎？因爲它可以通過兩種方式完成。 –

我已經解決了這個問題！謝謝 – Thibaut

@Thibaut如果你自己解決了這個問題，那麼你應該1）添加你的解決方案作爲這個問題的答案或2）刪除這個問題。 – user1429080

添加一個文本框即

<asp:TextBox ID="TextBoxSearch" runat="server" AutoPostBack="True"/>

和修改您的SqlDataSource類似下面。

 <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
      ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
      SelectCommand="SELECT [PatientName], [Quantity], [MedicineType],[ContactId],[MedicineTypeID],[MedicineID], [MedicineName] FROM [Patient]" FilterExpression="[PatientName] LIKE '%{0}%'" > 
      <FilterParameters> 
       <asp:ControlParameter ControlID="TextBoxSearch" DefaultValue="" Name="PatientName" PropertyName="Text" Type="String" /> 
      </FilterParameters> 
     </asp:SqlDataSource>

它被測試和完美工作。希望能幫助到你。關心！
