I'm new to lightswitch and i searched lot, but couldn't find proper solution for this simple question. I need to add items to combo box, based on user selection. ( not from existing table)
For example if user select country ,following towns must add to combo box.
USA - Texas, New York etc
UK - London , Surrey
How can i do this? i'm using vb.net as my back end. i found this article How to create an unbound combobox as useful one. but couldn't able work according to my scenario.
what is the way to add items to combo box?
In Lightswitch, if you want to have a dynamic set of data bound to a control, that data must be in a table. You then need to create a query that filters the data in that table based on the user's selection and bind your control to that query.
Here is a pair of articles that describes implementing a situation that is similar to yours:
Nested AutoCompleteBox for data entry
Nested AutoCompleteBox for data entry Part 2
We can't directly assign our own values to combo box. we have to use either data table ( as mentioned by embedded.kyle ) or we have to create custom control to assign values.
i have used custom User Control for above scenario. detail step that i followed can be found in following Link
Adding a record that doesn't already exist in a bound table is a very common scenario. Unfortunately, there's no out-of-the-box way to do this in LightSwitch, you simply have to write code to achieve it, like in this blog post.
Add non existent records using AutoCompleteBox
Or, of course as was also suggested, you could create a custom control to do the job.

How to query combo box of only current record/row in Access data entry form?

Closed 1 year ago.
I am trying to make a dependent drop down work with my database here but it is giving me a hard time for different reasons that I will explain.
This is what I have:
A form called "tblOTS" (split form based on an actual "tblOTS" table):
As well as a table called "tblAlphaCode":
When looking at the property sheet for the "Alpha Code" combobox (actually called "strOTSAlphaCode") on my tblOTS form, this is what I have:
The current SQL statement under "Row Source" for this strOTSAlphaCode is:
SELECT tblAlphaCode.strAlphaCode, tblAlphaCode.strCategory,
tblAlphaCode.ID, tblAlphaCode.numSortingOrder
FROM tblAlphaCode
ORDER BY tblAlphaCode.strCategory, tblAlphaCode.numSortingOrder;
Basically, when user select an Alpha code in the drop down from "tblOTS" form, it adds the ID of the tblAlphaCodes into the actual tblOTS record.
My goal is to have the user select first a "Category" (here FASTENERS/HARDWARE ...) when adding/modifying an OTS record, and then have the "Alpha Code" drop down dependent on what category was just selected.
I first tried to changed the SQL statement using a WHERE condition on the category field, based on the form category field itself:
SELECT tblAlphaCode.strAlphaCode, tblAlphaCode.strCategory, tblAlphaCode.ID, tblAlphaCode.numSortingOrder
FROM tblAlphaCode
WHERE (((tblAlphaCode.strCategory)=[Forms]![tblOTS]![strOTSCategory]))
ORDER BY tblAlphaCode.strCategory, tblAlphaCode.numSortingOrder;
And created a strOTSAlphaCode.requery in my Form_Current event to update it everytime.
However, it affects the whole form itself as my control source is directly affected by my Row Source in this instance, and the form looks like this:
You can see that the drop down is working beautifully, however, all the fields that do not have the same category as the current record that I work on (FASTENER <> HARDWARE here), are missing their Alpha code (the second record is missing "O-RING" compared to the first picture from this post); this behavior is problematic!
I tried to find workarounds by changing strOTSAlphaCode into a simple text box only containing the Alpha Code ID, added an unbound text box on top with dlookup function to find the actual alpha code related to this ID, and an unbound combobox in between with the exact same SQL statement inside the Row Source Property, that would update the strOTSAlphaCode with some VBA ... not ideal right?? Ahaha. This is why I believe there is a simpler way that I am not aware of, but also I would like to use a "search as you type" code for this combobox later on and this solution was making it very difficult.
How can I make this work? I believe the answer is a simple/different SQL statement to put in my Row Source property, that is probably something related to some type of JOIN statement? Or something else? I expect to write some VBA code to make all of this work flawlessly, but I want to make sure that I have the right SQL statement first.
Thank you June7;
Yes, the link you gave me ( this link ) states 2 solutions, and the second one is the one that I talked about when describing my problem:
for forms in Continuous or Datasheet view, include lookup table in form RecordSource, bind a textbox to descriptive field from lookup
table, position textbox on top of combobox, set textbox as Locked Yes
and TabStop No
So I guess, the answer is that I MUST have a textbox with dlookup setup for my case; I put it on "locked" so that if the user wants to change it by typing in it, he will first have to select the arrow. This will work with what I wanted to do
Cheers,
I am currently building a MS Access database as a project #Work.
The Database is fed with a huge, not sorted Table DataQueryExport, and the objective is to create a GUI that makes that huge table workable.
Now to the question:
I have a textfield Comment that is supposed to show a comment to a specific data entry WorkID. The WorkID Is stored in a seperate table called WorkID_Comments which is filled via SQL query. The Table WorkID_Commentshas 2 columns, WorkIDand Comment.
The GUI has a ComboBox WorkID_Combo, where you can select a specific WorkID from the main Table DataQueryExport. This exact value is what is supposed to be used as a reference to show the comment for that WorkID.
TL:DR; I need the Comment Box to show and store the Text I wrote for that Value selected in the ComboBox. How do I get the Textfield to show the Value from the Table WorkID_Comments.Comments where the Value in WorkID_Combo(View ComboBox) is the same as WorkID_Comments.WorkID
I apologize beforehand for any weird capitalizations, I am used to it, German is my main language.
Thank you for reading, I am thankful for any response.
Build a query in the query designer with your needed columns (If I understood it correctly: ID and the Comment).
Then go to your combobox and chose under properties recordsource table/query and your designed query.
Now you can specify which colums should be shown and use the ID as the value in the background.
Then bind another query to your form (here is the text you wrote as column) which is linked to the ID from the combox. Put a textbox in the form and use the column as source.
I need to create a drop-down box so that an employee can select a pre-set reason in the "RE:" field of a Report. There are only two selections that need to be in the box: "personal events" and "lack of adequate notice".
The report itself is already made and there are a number of fields that link back to the database - name, address, specific dates, etc that are already in the report. I've figured out how to make the drop-down box using the combo box function in a form but is there any way I can merge the combo box into the report?
I'm a beginner, by the way so I'm still figuring things out.
Currently your report sits on a query (query get relevant data from the table)
Steps to follow:-
Change the table by adding a column with the two options you just
mentioned above
Add combobox to Form with items as the two options
Adjust your query to use these options as a criteria to change
results returned by the query
Show the results in the report as you are showing right now.
If you have a code already, please post that snippet. So we can help you accordingly.
Some reference for you to get ideas
BUT I HAVE A DOUBT, ARE YOU TRYING TO SAY YOU WANT TO SWTICH BETWEEN TWO REPORTS BASED ON THE USER CHOICE SELECTED IN COMBOBOX?
I'm using a data view to display a list (Sharepoint 2010) that has several columns including one that has a Name column. I've provided the user with a text filter on the page to send values to filter the Name column in this list. The problem I'm facing is that the filter only works for exact matches and not partial matches.
I tried to overcome this problem by using Sharepoint Designer to:
create a parameter that uses the textbox control value.
Filtering the Name column with this parameter and setting the comparison to "Contains"
Unfortunately if the default value of the Parameter is blank, the list does not display any data. If the default value of the parameter is set to part of a name in the list, the list displays names that contain that string. However, when changing the value in the text box and searching, the list does not return results. Please let me know if you guys know how to fix this. Any help is much appreciated and let me know if you need any additional information. Thanks!
Managed to find a solution to my problem. I used a custom javascript solution designed by jvossers (http://instantlistfilter.codeplex.com) that involves the list being filtered instantly much like Google's search!
The only downside of this solution is that it only filters the items currently displayed on the screen. Therefore, if you have a data view web part which limits the amount of items displayed on the page, this solution won't help you. In order to facilitate this solution, display all the row items on the page (by increasing the item limit per page to a larger number than your total list rows) and then add this code into a content editor web part on the same page. Worked brilliantly for me. '
By the way if you are using jQuery 1.3.x or higher, you should modify the script a little as described in the disscussion here: http://instantlistfilter.codeplex.com/Thread/View.aspx?ThreadId=49123
I am trying to populate one column in an Access table using two check boxes - one for 0, one for 10. How do I make it so that on click or after update, whichever check box is checked populates the cell with the associated number?
Any assistance (if there's a better way to choose from two values?) would be much appreciated.
Regards,
Steve
A check box does not seem to me appropriate for selecting between 0 and 10, since
you cannot bind it as such to field in your table
it is a control commonly associated with Yes/No values
I would rather go here with an Option group (if you have enough space) or with a combo box (drop down list).
You did not mention if the field is Required nor the type of field. If field is not Required (meaning it must handle Null value), go for the Combo.
A toggle button is probably more what you're looking for. A drop down list would work as well.
