Microsoft access dynamic subforms

Is this about the direction you want to go? Hans, many many many thanks! Imb, thanks for your input. The following table defines some of the terminology that is associated with subforms. Access will handle most of the details if you use the procedures in this article, but it is helpful to know what is occurring behind the scenes if you need to make modifications later.

The control that embeds a form into a form. You can think of the subform control as a "view" of another object in your database, whether it is another form, a table, or a query. The subform control provides properties which allow you to link the data displayed in the control to the data on the main form.

A simple display of data in rows and columns, much like a spreadsheet. The subform control displays a datasheet when its source object is a table or query, or when its source object is a form whose Default View property is set to Datasheet. In these cases, the subform is sometimes referred to as a datasheet or subdatasheet instead of as a subform. The property of the subform control that specifies which field or fields in the subform link the subform to the main form.

The property of the subform control that specifies which field or fields on the main form link the main form to the subform. For best results, establish table relationships before following the procedures in this article. This enables Access to automatically create the links between subforms and main forms. When a subform control has a form as its source object, it contains the fields that you place on the form, and it can be viewed as a single form, continuous form, or datasheet.

You can insert a datasheet or pivot view into a form by creating a subform control whose source object is a table or query. For more information, see the section Add related data to a form without creating a subform. You want Access to create both a main form and a subform, and to link the subform to the main form. You want to use an existing form as the main form, but you want Access to create a new subform and add it to the main form.

Add one or more subforms to an existing form by using the Subform Wizard. You want to use an existing form as the main form, and you want to add one or more existing forms to that form as subforms. This procedure creates a new form and subform combination by using the Form Wizard. This is also the quickest way to get started if you have not already created the forms that you want to use as the main form or the subform.

On the Create tab, in the Forms group, click Form Wizard. For this example, to create an Employees form that displays orders for each employee in a subform, we will select Table: Employees the "one" side of the one-to-many relationship. Note: It does not matter which table or query you choose first. For this example, we will select the Orders table the "many" side of the one-to-many relationship.

When you click Next , assuming that you set up the relationships correctly before you started the wizard, the wizard asks How do you want to view your data? Select the table on the "one" side of the one-to-many relationship. For this example, to create the Employees form, we will click by Employees.

The wizard displays a small diagram of a form. The page should resemble the following illustration:. Note: If the wizard does not ask How do you want to view your data?

The wizard will continue, but Access will not add a subform to the form. You might want to click Cancel and examine your table relationships before you continue. At the bottom of the wizard page, select Form with subform s , and then click Next. On the What layout would you like for your subform?

Both layout styles arrange the subform data in rows and columns, but a tabular layout is more customizable. You can add color, graphics, and other formatting elements to a tabular subform, whereas a datasheet is more compact, like the datasheet view of a table. On the next page of the wizard, select a formatting style for the form, and then click Next.

If you chose Tabular on the previous page, the formatting style you choose will also be applied to the subform. On the last page of the wizard, type the titles that you want for the forms. Access names the forms based on the titles that you type, and labels the subform based on the title that you type for the subform.

And to top it off, I can not even get into the subforms. I've even shut the form down completely and re-opened it. Clients with data appear fine, but clients without data in the subforms have blank subforms. Given that the subforms function fine as long as there is data, I have to believe that the linkages are set up right but that there is a property that I am not setting correctly.

Well, it turns out this is not the case. I've inspected the database you sent, and it's quite clear what's wrong; in fact, it's the very first thing I asked about. I said:. The simplest reason for being unable to add new records to a form is that the form's AllowAdditions property is set to False. I'm talking about your subform, in this case. Check that, but it's not likely to be the case because you probably would not have set the form up that way. But in fact in your subforms, all of the "Allow So the subforms are entirely uneditable.

Not only can you not add new records, but you can't edit or delete existing records. I asked if you could edit existing records on the subform, and you said you could. But you can't in the database you sent me.

Were you confused as to which form I was asking about? Maybe you looked at the parent form, which in this case is your form called "frmSubClientContacts", and not the subforms which are having the problem.

I don't know how these forms got their "Allow If you had intentionally set them that way, I would have thought you intended the forms to be read-only, and would have recognized that as the cause of the problem when I described its effects. Forms and subforms are blank like that when two conditions are true: 1 there are no existing records to be displayed, and 2 it is not possible to add a new record.

We know that 1 is true for a new client, so we have to investigate why 2 is true. The most common reason for being unable to add records to a form when you didn't intend it to be that way is that the form's RecordSource query is not updatable. Not all queries are updatable, and some are only partially updatable.
