    <p>Ok, the issue is with how your accessing the information, try getting at it through the sizer:</p> <pre><code>self.tc_all = [] for child in self.inputsizer.GetChildren(): self.tc_all.append(child.GetWindow().GetValue()) self.tc_all = sorted(self.tc_all) for child,item in zip(self.inputsizer.GetChildren(),self.tc_all): child.GetWindow().SetValue(item) self.inputsizer.Layout() </code></pre> <p>So here's whats going on here. Every sizer has children called "sizer items" (documentation <a href="http://www.wxpython.org/docs/api/wx.SizerItem-class.html" rel="nofollow">here</a>) which are representations of your items on the GUI. Calling <code>GetChildren()</code> on any sizer will return a list of all of that sizer's sizer items. Note that these are note the items themselves, so you need to take one more step, and that is the <code>GetWindow()</code> function. The result of <code>GetWindow()</code> on a sizer item is to return the actual item (or widget) that the sizer item represents, in the case a <code>TextCtrl</code> item. Once you have that, you can treat is as you normally would. </p> <p><em><strong>BE CAREFUL</em></strong> when using the <code>GetChildren()</code> function on a sizer that contains multiple items, as it returns <strong>all</strong> the children. So your code will break if you try to call <code>SetValue()</code> on something which does not support that method, such at <code>StaticText</code></p> <p>Hope this helps</p> <p><strong>EDIT:</strong> The actual answer was an issue with sizers resulting from nesting panels. Editing the sizers in the nested panel caused the strange behavior noted in the question.</p>

    1. COthank you! But it still doesn't work. At first, in your last line it has to be *str(item)* instead of *item*. But that's not the problem. The TextCtrls still (or again) change into the old value on mouse hover.

    2. CObtw: in my example *self.tc_all* is a list with all my TextCtrls, not the list with the values of them. And I get the values with a normal loop *values.append(self.tc_all[i].GetValue())* instead of using your first three lines - but this isn't the problem because in both cases we get a list with the (sorted) values of all TextCtrls.

    3. COYeah, I figured it would be easier to use ```self.tc_all``` as a list of values, since you can store that as a sorted list. In regards to your first comment, you shouldn't need ```str(item)``` since the list is of the values (which all should be strings anyways). What type of value is it giving you? Also, I added a line to my answer

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
