I create a table and a form out of the table. However, after I change the property of the item in a table, (say, make it from direct text input to a yes/no list), the same item in form does not update automatically for that. Is there a way to make MS Access to do this job?

So I have a database where I have a list of defined terms that get added to a record.
I have it set up so a combo box displays the terms and these get added to a field.
What I would like is the definition field for the term to appear in a text box next to the combo box.
So far I can get it to display the term by simply referring to it by having the control source be "=[Term]". But what I want is to refer to a column within the query used to get the terms in the combo box.
How would I do this? Is there a way of getting the value from one of the hidden columns of a combo box to appear in another place? Even as hover text would be good...
You would use:
=[Term].[Column](n)
where n is the zero-based index of the column to retrieve.
what i am trying to achieve is to have data populate a datagrid from a query, this part works fine. but once the data has been populated i want to add an additional row which the user will be able to type into. so for example the grid will have 5 pre populated rows and then the 6th row will be empty cells which the user can edit. the final column of this row will either be a button or an image with the click property set. this will be used to run an update query to update the dataprovider of the datagrid.
This is pretty easy. Just add a new object in your List that is bound to the datagrid. For the final column you will need an item renderer.
Ex:
dataGrid.dataProvider = someList;
//later when it is populated
someList.addItem(new Item());
After this you can set the focus to the desired column and the last row to show its input time.
You can also remove the last added item from the list to simulate a cancel action.
You will also need to set the 'editable' property of the grid to true. Set the selectionMode property to 'singleRow' Each column also has an individual 'editable' property so you can limit users to only changing certain properties.
As long as the data is simple text the default item editor (which is a textInput) will work fine. If you use an advancedDataGrid you can also include things like checkBoxes for Boolean data.
I want to create a sale order form. For which the form should allow insertion of line items. I dont want to restrict the number of line items. I decided to display 4 empty records in which user is allowed to type line items. If he wants to type the 5th line item then i have to make the 5th empty row visible to the user. using a scroll bar he should be able to see the first record also.
How to do this in oracle forms 10g.
Any help will be appreciated.
Set the Number of Records Displayed property of the line item block to 4 and the Show Scrollbar property to Yes.
add text item based on your table (in the proprety
database-yes ,and write ehich table the item base)
on the property of the block do the scrollbar property to yes.
add simple button to the forms and wrie commit_form.
try it
I have two tables: Parent and Child. The child records pre-exist in the table. I want to create a form for Parent with a subform with collection of Children, and want to a child. New children should never be created here. Selected children will have the FK-attribute set to the PK of the parent.
Is this possible in MS Access 2010?
Thanks...
One way would be to create the form and subform and set the Allow Additions property of the subform to No, this will prevent children being created. Next, add a button to the row called, let us say, Assign, the Click event of this button would then update the FK for children to the PK for parents, say:
Me.txtParentID = Me.Parent.txtID
Human nature being what it is, you will probably need a form or button that allows parents to be removed when they are mistakenly assigned.
You may wish to exclude assigned children from your form.
There are, of course, several other ways to do this.
Edit
Presumably you have some field in the child table that indicates a parent, so you can use that to filter the unassigned children. The record source of you pop-up form would be something like:
SELECT ID, Something FROM Children WHERE ParentID Is Null
You can still have the assign buttom which could use an OpenArg from the main form with a message box to confirm, the ID directly from the main form, or an additional small form to select a parent.
I do not recommend a pop-up. Unless you make it application modal, it is possible that the user will move the main form record without paying sufficient attention and if you do make it application modal it will be a nuisance.
A subform of assigned children would be safer or an assign form listing only unassigned children that includes a combobox based on the child table parent id foreign key to select a parent. This could be a continuous form.
in Access 2007 how can I display text fields in drop down list while bundling to an ID? not while selecting (we can do this by plying with the width field. but what I need after selecting?
Do we create a hidden field that stores the ID?
Your description of how a combo box works is correct. Keep in mind that while you're setting the first column and display length to zero, that means the combo box will then search by the second text column. The combo box will display by that second text column after you select a value. In fact in all cases for typing in a value, even partial matching as you type, a simple select of a value will ALL BE done by the displayed text column but in ALL CASES it will save the actual ID (the first column) into the table that the form is bound to.
So no additional coding or anything if need be done on your part to achieve the above goal and in fact this is pretty much the default as to how combo boxes work inside of ms access.
What makes the combo box is somewhat unique inside of Access is you can have more then 2 columns. And, in the combo box settins you can choose what column is to be selected and saved into the table. And, the combo box has both before update (with a cancel), and after update and also a Not in List event that fires in the case of a user tyring to type in a value that not in the list.
So, the Access combo box is quite flexible. The source for the list or members displayed in the combo box can be based on a table, on a query, or you can even type in a value list that is saved inside of the property sheet. And, another option is to fill the combo box is by using call backs (so, again quite a few ways to fill out the list of memebers for selectiogn).
So, keep in mind there is two aspects to the combo box. There's a so called row data source or how you feed the members that will display in the combo box. Then there is the underlying column (field) that you bind that control to when you select a value. That is in the case when the combo box is bound.
As mentioned, the bound column setting is another property in terms of inside the combo box, and you don't need to write any additional code to achieve that above goal in your question.
Albert Thank you for this excellent explanation.
I found out that the bound column has no effect. Acces take the first visible field and bound to it regardless of what you have in the bound column property.
All good thanks
