其實我正在開發模板使用asp.net和c#。
我使用的ListView在我的ascx頁面,我的ItemTemplate中是如下:如何在代碼隱藏中更改listview中的標籤值?
<ItemTemplate>
<tr style="background-color:#FFF8DC;color: #000000;">
<td>
<asp:Button ID="DeleteButton" runat="server" CommandName="Delete" Text="Delete" CausesValidation="false" OnClientClick="return confirm('Are you sure you want to delete this Product Details?');" />
<asp:Button ID="EditButton" runat="server" CommandName="Edit" Text="Edit" CausesValidation="True" />
</td>
<td>
<asp:Label ID="EmpIDLabel" runat="server" Text='<%# Eval("EmpID") %>' />
</td>
<td>
<asp:Label ID="EmpNameLabel" runat="server" Text='<%# Eval("EmpName") %>' />
</td>
<td>
<asp:Label ID="DepartmentLabel" runat="server" Text='<%# Eval("Department") %>' />
</td>
<td>
<asp:Label ID="AgeLabel" runat="server" Text='<%# Eval("Age") %>' />
</td>
<td>
<asp:Label ID="AddressLabel" runat="server" Text='<%# Eval("Address") %>' />
</td>
</tr>
</ItemTemplate>
,我從數據庫中檢索的數據ASCX後面的代碼波紋管:
public DataTable GetEmployee(string query)
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString);
SqlDataAdapter ada = new SqlDataAdapter(query, con);
DataTable dtEmp = new DataTable();
ada.Fill(dtEmp);
return dtEmp;
}
,也是我綁定在ASCX代碼背後的數據如下:
private void BindLVP(string SortExpression)
{
string UpdateQuery = "Select * from Employee" + SortExpression;
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString);
hid_UpdateQTP.Value = UpdateQuery;
lvProduct.Items.Clear();
lvProduct.DataSource = GetEmployee(UpdateQuery);
lvProduct.DataBind();
}
我的問題是我怎麼能刪除<%# Eval("EmpID") %>
和所有其他的標籤文字像這在ItemTemplate中,並從後面的代碼中更改ItemTemplate中的label.text,我的意思是將數據庫的數據從後面的代碼傳遞到這些標籤。
感謝您的考慮。
