Vb updating combobox value
In this tutorial, we'll look at how the Excel Combo Box code works.First, we'll create VBA code for a single column Combo Box list, and then we'll create Excel VBA code for a Combo Box with two columns.I mean, it should be obvious that setting the Display Member on a List Control that already has a current data source is going to invalidate the control and require it to refresh to display the new values in the list. The fact that the IDE can prompt you with known properties of the type provided by the binding source appears to be some extra IDE sugar that Microsoft has decided to bestow on us. If the same holds true for the Value Member, then it would also follow that changing both of those properties on a List Control with a datasource is going to result in two updates (if it worked as you expected), which then leads us to the question of why would one want to do it that way to start with? So, I think we just need to resign ourselves to the fact that we should set the Data Source to null before setting either or both of the other related properties, and then set it back to a valid datasource afterwards, to avoid redundant refreshes, if for nothing else. So, if this is about the fact that the documentation doesn't make any of that crystal clear, then you're going to be doing a lot of writing about deficient documentation in the future , because it's quite common for behavior like this to not be clearly or formally documented, and often can only be found in the comments accompanying code samples. This article is highlighting the inconsistencies when databinding the combobox from code. It doesn't because it doesn't require a datasource to set those properties, so I really don't have the slightest idea what you're getting at, other than it being just your way of saying that you were not aware that it was possible to do what I just suggested. No, I agree with everything you said in your second post. The designer will only show the names of the available fields for the Display Member and the Value Member combos if you first populate the Data Source combo, and that this 'suggests' that the Data Source should be populated first. Data Source = this.animal Binding Source; this.combo Box3.
You might chronologically set the Display Member and Value Member properties before you set the Data Source property in the MS Designer, but if you look at the *.
Yes, it does that when it has a Data Source, but my point was that it is not required that you set a Data Source before setting Display Member or Value Member.
If you set either of those to an invalid member name, you get the error when you set the datasource.
Data Source = this.animal Binding Source; this.combo Box2.
In this video, you'll see the code that fills the items in the combo boxes on the Excel User Form that was created in this tutorial: Create a User Form The written explanation of the code is shown below the video.
