Question

当用户在我的数据网格视图中选择一行时，数据网格视图外部的标签不会更新。

这是我的datagridview

正如您在Visual Studio中看到的那样，将捕获所选行的值。但是从视觉上看，它不会更新。

这是我的数据网格代码的样子。

import tkinter as tk

class MainWindow(tk.Frame):
    counter = 0
    def __init__(self, *args, **kwargs):
        tk.Frame.__init__(self, *args, **kwargs)
        self.button = tk.Button(self, text="Create new window",
                                command=self.create_window)
        self.button.grid(padx = 5, pady = 5, row = 1, column = 3)

    def create_window(self):
        height = 2
        width = 3
        numberA=0
        achievs = ["1", "2", "3", "4", "5", "6"]

        self.counter += 1
        t = tk.Toplevel(self)
        t.wm_title("Window #%s" % self.counter)
        for i in range(height): #Rows
            for j in range(width): #Columns
                gridVal = tk.Label(t, text=achievs[numberA], relief=tk.RIDGE)
                gridVal.grid(row=i, column=j)
                numberA = numberA + 1

if __name__ == "__main__":
    root = tk.Tk()
    main = MainWindow(root)
    main.grid(row=4, column=5, padx=5, pady=25)
    root.mainloop()

这是网格外部的标签代码的样子

<asp:UpdatePanel ID="uplPanel"  runat="server" >
            <ContentTemplate>
           <asp:GridView ID="gvInventario" runat="server" AutoGenerateColumns="false"  AllowSorting="true" ShowFooter="false" DataKeyNames="componente_id, ubicacion_id, proveedor_id"  PageSize="20"
                ShowHeaderWhenEmpty="true" AllowPaging="True" OnPageIndexChanging="gridView_PageIndexChanging" OnSelectedIndexChanged="OnSelectedIndexChanged" OnRowDataBound="OnRowDataBound"
                 CellPadding="3"  AllowColumResize="True" onsorting="grdDetails_Sorting" GridLines="None" CssClass="mGrid" PagerStyle-CssClass="pgr" AlternatingRowStyle-CssClass="alt">    
                <Columns>

Answer 1

检查您是否使用了正确的标签ID。因为在您的示例中，标签ID不一致。在您的活动中更新正确的标签。

我将UpdateMode =“ Conditional”更改为UpdateMode =“ Always”多亏了我在how to update a control in another updatepanel?
