I am using SL5 based ComponentOne's C1FlexGrid and binding data to the control at runtime. For two columns, I am populating lookup data as dropdowns in the first and second column of the control. In the first column, I am binding company information and in the second column, I am binding department information by default. There is a 1-N relation between Company and Department entities in my model (that is, for every company, there are N no of departments associated to it).
In edit mode, I want to filter out departments in the second column of the control for the selected company in the first column (that is, when I select "company 1" in the dropdown, I want to bind only those departments associated to company 1 in the second dropdown). Is
this achievable?
I have achieved this by following the suggestion mentioned in the forum post Different drop down list/combo box in the same column? .

I currently have these options set in a combo box:
This box will show the projectIDs that a current company has which is set with the criteria. I just want to show the name of the project as people will not know just by the id. If I remove the check box for the projectID it will just remove that field completly and not show anything. I have debugged what companyBox.Value is and it is indeed a number for a company and if taken this id and replaced it with the following query which is built from the picture and it returns the results I want. I just cant get the values to show in the combo box.
SELECT projects.projectName
FROM companys INNER JOIN projects ON companys.companyID = projects.companyID
WHERE (((companys.companyID)=7));
Gives me all the projectNames where the companyID is 7
And as seen below that same query just gives me blank spaces instead of the names:
Ok, if you have say a query, then as noted, then you can use a "join" to pull in the other table (based on that "projectID").
So, for a general report etc., then your approach of using the query you have is correct.
HOWEVER!!!
For a combo box? They have this feature and ability built in. In other words you do NOT in general need a join.
The combo box has two parts:
A sql query that "drives" or "fills" the combo box. This can (and will be) of course based on the Projects table.
VERY important:
Our combo box is to save, store, put, use the project ID into a column in our CURRENT form. That form of course is based on a differnt table (the forms current table). So, keep in mind the two concpets:
Combo box can be driven by any table to display data.
Combo box will/can use a column from that "other" table to SAVE into a current column on the current form.
Now of course the Project "id" is the VALUE we want, but we sure as don't want to display that "project id" value, since as you note, humans want the nice looking text.
First Rule:
ALWAYS, but ALWAYS make sure the FIRST column of the combo box "sql query" is the column we WANT to save into the current form, but ALSO the column we are going to HIDE AND NOT show to the user.
So, a combo box can with great ease HIDE the first column. You can hide other columns, but as a general rule a VERY HIGH number of my combo boxs will have two columns. So, you might need company "id", but would want to display company name as nice text to the user, but store/save/use the "id" of company for this purpose.
So, in your case? Change the order of your columns.
You want:
ProjectID, ProjectName, and you ALSO can continue to have a filter based on company.
So, once you get above setup, and you WILL NOT need a sql join. Remember, the combo box has it own "whole sql statement" based on table projects.
So, the combo box will:
Save/store/use the ProjectID when you select a project.
And it will display the project name, but behind the scenes it will use + save ProjectID.
So, just make sure that you set the length of the first column in the combo box to 0 (to hide that projectID from display).
Next, make sure you set WHICH column value from the query the combo box is to save.
That column will be the FIRST column, so you want to set that to 1
Your combo settings will look something like this:
In above, the CONTROL source is your CURRENT form and table.
So, I want to get a Hotel "ID" from the table hotels, but I am going to save the results of the combo box selection INTO a column called Hotel_ID
And note VERY careful - I set the bound column = 1 (that is the FIRST value from the query that drives the combo box.
Next up:
We want to hide the first column value, so you need this setting in format tab of the property sheet for the combo box:
NOTE VERY close in above. I set the FIRST column width = 0. this is HOW you hide the "ID" of hotels - I only want the user to see the nice hotel name. (or in your case Project name).
But, the 2nd column, I have a width for the Hotel name (or in your case project name).
So, make your first column in the query for the combo box the "id" of project id. Set the width of the first column = 0.
So, the query that drives the combo box? It is based on the ONE table, but you need to ensure that the "id" that you going to use is the first column, and simple hide it from display.
So, a combo box has a sql query that drives the combo box, and that query in most cases will NOT be the current table.
So, you have to set BOTH settings (the column the combo sql query will use - but to avoid confusing, then just adopt the habit of making the 1st column the "id" or value you want from that sql.
But, after setting above, you STILL have to set what column to shove/put that column into on the current form. (that setting is the control source).
In effect, a combo box is a kind of look-up into the other table, and it can display nice user friendly text columns, but still use + store the ID.
So, your query should look more like this:
SELECT ID, projectName
FROM projects
WHERE (((companys.companyID)=7));
I don't know if your first column of Projects table is "ID" (or is it ProjectID), but as you can see, the combo box ONLY needs to be based on the one table, and with our new rule - we always use the first column of the query the "id" value we want.
Now, of course the above is "hard coded" for company, and your original query that drives the combo box was fine - just that the order of the columns display was incorrect.
I have a tbl_ProjectList that includes the project's Name and End Date.
A qry_cboProject queries this table to only display projects in a combobox on Subform A where the End Date is after the selected date on Subform B, both on Mainform C.
On Subform A, a macro copies (INSERT INTO SQL) projects from Subform B's previous months into the new months. However, if an out-of-date project gets copied over to a new month, the combobox field would be empty for that record, even though the Key exists on the back-end.
I've tried playing with the combobox's properties on Subform A by changing the Bound Column, Column Count, Column Widths, and Limit To List, but am only able to get the out-of-date project to display by its Key, rather than its Name.
The front-end reasoning for this macro is that employees do not have to repetitively select the same projects for each month, and employees already working on out-of-date projects may still need to put in some hours to close out the project.
Does anyone have any suggestions? Thank you in advance!
The order in which fields show up in you combo box depends on how the control source is querying the information i.e. to get name and not the key to show up in a combobox using the a control source query like the following:
SELECT Key, Name FROM tbl_ProjectList
You would need to set the following attributes:
Column Count: 2
Column Width: 0"; 2"
Bound Column: 1
It sounds like you may need to requery the control source as well. This should cause all the information to update.
#Parfait - apologies for not describing my problem in more detail. There are multiple subforms on one main form to allow the user to select a date in one subform, which populates projects on a second subform and responsibilities on a third subform.
Jeffrey's suggestion made me realize that the underlying query to the combobox should be adjusted for projects that are carried over into new months, where a foreign key exists in the underlying tbl_ProjectUserEntry
Therefore, I added a WHERE criteria to the query, which uses a DLookUp function to see if the foreign key exists:
DLookUp("[DateID]","tbl_ProjectUserEntry","[DateID] =" & Forms.frm_UserEntry.tbDateID) IS NOT NULL
frm_UserEntry is the main form..
Again, apologies for my brief description to a complex problem.
Guys!
I'm working on a project with Bizagi Suite - Version 11.1. I'm new to it and I will really appreciate your help, because I'm having a hard time creating a dynamic combobox control.
So my case is the following:
Data Model: 3 master tables: Program, Order and Order-Program (m-m relationship). In table Program users fill out year, positions and amounts for each position. In table Order, they fill out info about the order and they have to specify from which program they want to take the money out for the order. The Program itself has a lot of records with different positions and amount. And I want when the users fill out the order to select the year, the position and the amount they want to take out of the program. So I need to have a dynamic combobox for the field 'position' which loads when user select year.
In other words I need to load combobox with filtered records of master table.
Do you have any ideas how I can do that?
Thank you in advance!
Best regards,
A.Mincheva
You must define your combobox with the full content of the master table.
Then ,you can define a Filter expression to dynamically filter the combobox content.
In the filter expression, you need to retreive the value of selected Year with XPath and use this value to filter the records.
In the form designer, you go to "Actions & Validations" to define the following action :
When "Year" changes <=The display name of the input field
Then Refresh "Program" <=The display name of your dynamic combobox
I'm using a linked view in Access from the SQL server.
That view contains an employee_name column and many other columns (like equipment , parking, room, date etc). There is a row for each new entry (for example an employee got a new phone at a date and then at another date he got another phone), therefore there are multiple rows for the same employee name.
What I need to achieve is having all the entries in a form from an employee.
What I have tried so far is creating a form based on that view and adding a combobox with the option "find a record on my form based on the value I selected in my combo box active". The problem was that I was seeing users multiple times due to the new enteries mentioned above. I fixed this by doing a select distinct on the employee name in the row source tab.
But now I'm getting only the first entry for an user, what I want is to get all the enteries (maybe in auto-generated textboxes, or anything which will be easy to export to excel, since that would be my next step - to have a button which can generate a report based on the user with all the corresponding entries) like I would have written SQL code like below:
select * from schemaName.viewName
where employee_name = '/*here use the selected name in the combobox'
Thank you for your help, I am a complete beginner to forms in Access and all of these great things one can achieve.
I am trying to make a simple form that 'registers' users into a meeting. I'm trying to get the form to submit the meeting 'id' into the database but I wish to display a different value for the user (so that they do not stumble through meeting id's). I've added two columns to the query (meeting id and meeting information) but I am unsure how I would get the form to submit the meeting ID but display the meeting information for the current user.
EDIT: I've tried your method Chris but it doesn't seem to work.

You need a rowsource query with TWO values because you have two columns. For example:
SELECT meeting_id, meeting_name
FROM meetings
In this case the 'bound column' property would be '1' because in the example you first select the meeting_id.
In the 'column width' property you then type "0cm;4cm". 0cm means that the first column (the IDs) will not be shown.
go to design view of the form and change the bound column to the number that represents the column you desire to have displayed. eg.
You can add the query at the Row Source as in the image a query builder will appear and you just create the query and save it.
