Richard Mace | I'm having an issue, manually adding items to a TButtonComboBox. As you can see from the first image, this is what I get when I add to the combo at run time. If I then click on it again, it displays correctly.
Any ideas? Attachments: 20170816_154512.jpg |

Another thing that might be worth mentioning, is that I have my own ShowModalX for passing parameters in, and then I call ShowModal to display the form. Richard |

Walter Matte Tactical Business Corporation | What is the variable AllAgents - what is it defined as? Understood - combobox.add.item - we know the method used to add the items - I think Tim's question was more along the lines of timing - when are you doing this - what event or function call is invoking the item.add ? More code around the flow is needed. FYI I use Application not Nil when creating forms in runtime. TfrmJobProperties.Create(nil) -> TfrmJobProperties.Create(Application) Just another thought - instead of your own ShowModalX - have property variables. - Create the Form - Set the properties - then in the setter you can initialize the comboboxes - Call Show or ShwoModal Walter |

And why not just have the form set with Visible = false in the IDE so you don't have to manually hide it? > and then in the JobFormProperties form, in the ShowModal, I have some code that retrieves some "Agents" from the EDB, and then on the returned event That will be the problem - the return is not happening properly - either you are doing it too early, or not calling it. FWIW, I use a DebugReport("message") routine which puts the messages into a multi-line edit which is normally invisible. This allows me to see the sequence of what is happening and when. (If you get into it, use a TStringList and then update occasionally from that, but I'm getting ahead of myself.) -- Matthew Jones |

If you're trying to load these after loading a dataset, then make sure that you've defined an event handler for the correct AfterLoad event for the dataset in question and make sure to call your drop-down loading code from there.
