    <p>I think the answer can be found in my first comment to your question. Let's look at this code:</p> <pre><code>procedure TFRelatiebeheer.SaveCancel(Sender: TObject); begin if (DRelatiebeheer.CID.State in [dsEdit, dsInsert]) then DRelatiebeheer.CID.Post; DRelatiebeheer.AID.Post; if DRelatiebeheer.CID.Post = Action then KJSMDBGrid1.RefreshData; KJPanel4.Visible := true; end; </code></pre> <p>The indentation is off. You think that you are setting <code>KJPanel4.Visible</code> inside the <code>if</code>, but you are not. Let's correct the indentation:</p> <pre><code>procedure TFRelatiebeheer.SaveCancel(Sender: TObject); begin if (DRelatiebeheer.CID.State in [dsEdit, dsInsert]) then DRelatiebeheer.CID.Post; DRelatiebeheer.AID.Post; if DRelatiebeheer.CID.Post = Action then KJSMDBGrid1.RefreshData; KJPanel4.Visible := true; end; </code></pre> <p>Do you see what has happened?</p> <p>Correct this with <code>begin/end</code>:</p> <pre><code>procedure TFRelatiebeheer.SaveCancel(Sender: TObject); begin if (DRelatiebeheer.CID.State in [dsEdit, dsInsert]) then DRelatiebeheer.CID.Post; DRelatiebeheer.AID.Post; if DRelatiebeheer.CID.Post = Action then begin KJSMDBGrid1.RefreshData; KJPanel4.Visible := true; end; end; </code></pre> <p>For what it is worth, where I work, our coding standard demands the use of <a href="http://docwiki.embarcadero.com/RADStudio/XE5/en/Declarations_and_Statements#Compound_Statements" rel="nofollow">compound statements</a>, with <code>begin/end</code>, and forbids the use of the single statement variant. In the past 15 years since we introduced this rule, we have not once encountered this mistake. Niklas Wirth knew that he had got it wrong and corrected the mistake in Modula-2. But it's simple enough to avoid the problem yourself just by forsaking single statement syntax.</p> <hr> <p>Update, as you and others point out, <code>if DRelatiebeheer.CID.Post = Action then</code> looks dubious. I honestly don't know enough about the classes that you are using to recommend a solution to that problem.</p>

    3. COI'm not sure about that. I don't actually know the types of any of the variables in the code.

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.
