I am new to asp.net and I have created an attendance system where I can a list of employees from the DB and when I click a button "In" it save a timestamp for when that employee came in.
So far, I have a normal table list of employees with the buttons in a separate column and I would like to change the design to look somewhat like the one in the attached image.
However, I do not know the what to use to be able to create that. Employee List ItemList

I have a Google App Maker project where I have a Many-To-Many Relation between 2 tables A and B.
I can build a page for table A where I have a table of related B records and add new ones using a dialog.
However, this approach enables me to create new B records and associate them to an A record but how can I make the user able to select an existing B record and associate it to an A record via UI?
I will need to have it work both ways (Select A records from B record page as well).
UPDATE:
I was to accomplish this by creating a separate dialog for selecting existing records which would show all available B records in a table widget with a SELECT button on each row. clicking the button will add the record to the B related records of the A record. However, I know there has to be an automatic way built by Google that will be less work and better design.
Thanks and I appreciate your help.
Your solution is a good one, another solution, depending on the number of existing records, is to use the multi-select widget. (You can bind the items to B's datasource, and values to the relation on a record in A. But as I mentioned, this only works well if the number of items in B is small.)
Making this easier is something we've been looking in to, the main challenge is the correct UI in this case depends a lot on the kind of app you're writing.
It took me a while to figure out the bindings for a multi-select but I think I am right in saying that they are
MultiSelect
Datasource: inherited: A
Values: #datasource.item.B
Option: #datasource.B.items
With this that Values are/is what you are updating in A(ie. A.B), but the Options you are updating it with are listed in B(ie. B.items).
Devin Taylor is right in his assertion that if you have a lot of records it may not work so well.
I am looking for the best way to store information that is entered within an Oracle ApEx app that is sectioned off like a wizard.
Basically there are a number of fields on the screen, i.e. text box, text area, select list, checkboxes as well as radiogroup buttons but are not attached to any particular database tables.
What I would like to do is basically have the user enter required answers say on one pane, which might have 5 items in total, i.e., 2 textfields, 1 radiogroup, 1 selectlist and 1 checkbox and when they press the "Next>" button before going to the next pane, store these answers into a ApEx Collection against a particular Id and perform the same process on the following pane of answers entered.
I am using Oracle ApEx 4.1.2. Basically want to store away values on the fly and reuse at a later stage.
As I mentioned in my last comment above, Plouf came through with the goods. I didn't require an ApEx Collection after all - regular items did the trick.
Basically I have a news page which stores headlines, stories, and a unique story identifier in a SQL database. I want to be able to create a hyperlink on a webpage to the pictures.
so when someone selects a news story from a drop down menu (which uses the headline) and presses submit I want to pass the storyID, which is a unique identifier, to a spot in a hyperlink. so if it was story 134 then then link would look like:
I know the SQL statement would look like:
SELECT StoryID from db.News
Where Headline = {The headline selected in the dropdown menu}
the dropdown menu is called NewsDrop
this would be an ASPX page written with a VB code base
SO I guess I need help passing the variables along to the search string and the hyperlink.
Not even sure if this is even possible.
There are a number of options available to achieve this, the most common would be to using a query string in the hyperlinks in your drop down menu to send a parameter to a SQL stored procedure which would use it in a variable in your select statement. So basically the hyperlinks you have in the drop down menu would be appended with ?storyID=<uniquestoryid> and on the far end SELECT StoryID from db.News Where StoryID = #StoryID it would be less efficient to use the headline from the link as a query string and variable in the where clause as you have shown but if that is your only option it could be done.
However you should proceed carefully when using query strings here is a link to a good basic article about query strings and another link about best practices.
I am having some difficulty trying to use checkboxes as the selectedIndex in a view based table.
There is good documentation on view based table here:
[View Based Tables ]
However, I after searching and looking on Stackoverflow I can't seem to get my implementation for doing the following.
My view is a table that makes a callout to Yahoo Finance. The table is view based constructed with bindings.
When the table is populated I want to have a check box against each row so that when the user clicks the check box, that row will be updated from Yahoo. Currently this works using multi or single selection using the table view and an observer.. I want to do this with the checkboxes and a button that gets all the checked rows.
The IB setup is as follows:
What is the best way to get the rows where the checkbox is selected? Should I use the array controller or do I need to do something with the table?
Assuming that you use a NSArray of NSDictionaries as your data model, why not add a key/value pair to each "stock" dictionary as a flag? Then in your button action method, just iterate through the data model and trigger an update when the flag is set. Bindings do the rest!
Using the ASP.NET grid view. It displays 3 columns with 1 row for each, displaying an integer saved in the database. I would like to have a text input one for each column, so the user can add a new row of integers to the database. (The table only displays the last row updated, that part seems to be working OK)
Here is the code I have that displays data but without the input option I would like.
What is the way this is done in ASP.NET (3.5)? Are there more options in the control or do I need to manually bring in text input controls and give each one manual code to update the database? Any help is appreciated.
Thank You.
Do you know the asp.net website? There are a lot of tutorials, e.g. about data access. You might find the information you need, e.g An Overview of Inserting, Updating, and Deleting Data.
Also check out the ASP.NET Dynamic Data section on the same page.
