How to automatically refresh the page where the iframe is located after the .aspx page in ifame is submitted through Button_Click. _html/css_WEB-ITnose

iframe, iframe button

There is a treeview plus an iframe in default.aspx

<asp:TreeView ID="TreeView1" runat="server" >                  <Nodes>           <asp:TreeNode Text="物资管理" Value="物资管理" SelectAction="Expand">       </Nodes>                </asp:TreeView><iframe id="iframe1"  width="100%" height="100%"  runat="server"></iframe>

The nodes of this treeview can be bound through background data reading, and the node value is single The Src that controls the iframe. When the Button_Click of a page in the iframe is submitted, the order number in the menu is also increased. The question now is how to refresh the node number in the treeview of this data-bound treeview in the Button_Click event.
Note: It would be best if you can use Ajiax’s UpdatePanel to update asynchronously

In fact, it is submission of the sub-page, refreshing the parent page is

Write a js function on the parent page, for example, the function is called reload (), write a js for page refresh, window.location.href=xxxxxx or the like;
After the sub-page is submitted successfully, just call parent.reload().

Missed. . .

After the sub-page is submitted successfully, call window.parent.reload();

No, the method is wrong
