I have a list view with two columns and I'd like to be able to save the value of the leftmost column for the selected row, or even better make it so that once the user clicks on either the right or left column of any given row, the entire row selects and not only the field that was clicked.
However I'm struggling to get the field saved which is more crucial than the row highlighting.
In a list box it would be
string = listbox1.selecteditem.tostring
However this doesn't seem to work for the list view. It won't even let me put "Selecteditem" and instead requires I put selecteditems, however this doesn't seem to do what I want either.
When I use the code:
string = ListView1.SelectedItems.ToString
I get the result of
string = "System.Windows.Forms.ListView+SelectedListViewItemCollection"
Despite the selected field actually being "EGG".
I need to have two columns so can't switch to using a listbox, although that seems like it would be the easier solution.
When I tried googling this question I could only find things for C#
Set FullRowSelect on to get the entire row to select.
SelectedItems.ToString refers to the collection of selected items.
SelectedItems(0).Text refers to the first selected item's text property.

I have an MS ACCESS Combo Box and I wish to change the value of one of the columns in a particular row. I get error "object required" when I run this line:
Me.ComboName.Column(12, intUseRow) = myVar
(If I am unable to use the above syntax then you should also know that the row I am trying to change is always going to be the "current" visible row so there may be another way of solving the problem due to this fact).
Thanks!
If you have a recordset that is bound to a Table/Query, you will need to change the underlying data then requery the combobox to see changes.
If you load it manually (like in the form load event) and have the comboBox Row Source Type to "Value List" - you should be able to update it like this:
Copy all the data from the selected row into variables.
Combobox.RemoveItem (selected index)
change the required variable to the new value.
construct the semicolon separated string for the value list entry
combobox.AddItem new-string.
a bit messy, but it works correctly!
is it possible to create listbox with multiple checkboxes in one row (Excel VBA)?
Thanks

I'm not sure I understood your question fully, but I'll elaborate on ListBoxes as much as I can.
First things first: Checkboxes and ListBoxes are different objects in Excel Userforms. The first is the little box that returns a "true/false". The second is a list of items which can be chosen. Clicking in a Checkbox will make the tick mark appear/disappear (or fade if tristate is enabled), while clicking a Listbox row will turn the listbox row "blue"/"white" (or whatever color is being used for the selected rows). In both elements, clicking is a way to toggle between True and False.
While a checkbox only allows for a single information to be marked as True or False, a Listbox allows you to select entries out of a list. That list may be inserted through code (.AddItem method) or passed from a range (.RowSource property)
ListBox objects allow for multiple columns of data to be attributed to one row element, but each row is an entire element (which means you cannot pick the element on row 3, column 2 - only all of row 3). The number of columns is established using the ColumnCount property.
By changing the value of the MultiSelect property, you'll allow the user to select multiple or single row elements simultaneously on your Listbox. Using the Selected( RowIndex ) property, you can check whether or not an item is currently selected (returns True/False). Remember that row indexes start at 0.
Finally, if you're using the MultiSelect property set to fmMultiSelectSingle and have a single column (as far as I know), the Text property can be used to return the selected item's value.
An easy example of a listbox is in Excel can be found at File > Options > Customize Ribbon (or something like that). There are two listboxes, one (on the left) with the visible items and another with the available items. A pair of command buttons is used to move items between boxes. That's a simple application you can likely find already setup online.
Am I on track to answer your question?
I have a datagridview which displays row numbers in the rowheaders on the left. One of the users has asked for them to be on the right instead. The display of row numbers is fine, it's the location of the rowheaders that's the issue here.
I have looked through various properties and can't find anything that switches the row header over to the other side.
I realise I could add another column to the right and format it to look like the rowheaders, but that seems like a clumsy workaround.
How about setting the RightToLeft property of the datagridview?
Me.DataGridView1.RightToLeft = Windows.Forms.RightToLeft.Yes
Bear in mind that this reverses the display order of the columns, which you would have to manage as well, if you want to give the appearance that the only thing to change is the position of the rowheader.
My query returns location_cd(string) and item_count(int). I only need certain rows from the result however and I need them to display in specific places in my layout so I don't think the table solution is going to work. Can I determine where I place the value for a particular row of the result set?
I am using a grid to display values for a number of fields. I cannot seem to be able to get the values from the results to show. The grid is bound to the result set. I even tried binding the cells to the result set but that didn't work either.
I checked in the query editor and there is a result set shown in the Preview so I know the query works. The complete and correct result set shows if I put a table on the page.
I tried inserting a Dynamic Text or Data object in a cell and used the expression:
dataSetRow["location_cd"]=="3SD"?dataSetRow["item_count"]:""
This returns a blank and does not seem to evaluate. I tested it with :
dataSetRow["location_cd"]=="3SD"?dataSetRow["item_count"]:"BLANK"
and got 'BLANK' to appear in that cell.
dataSetRow["location_cd"] and dataSetRow["item_count"] will display the location_cd and item_count from the first row of the result set. row.outer[] did the same thing. Obviously I am just hacking at this report at this point.
A co-worker suggested that she uses a JAVA if-statement in places like this but I could not get that to work either.
Any ideas or suggestions that will get me on the right road??
Thanks
An elegant option would be to use a HashMap storing the result of the dataset.
Declare a report variable named "values", with a new hashmap as default value (see image below)
Fill values in the onFetch script of the dataset: vars["values"].put(row["location_cd"],row["item_count"]);
Insert new data elements at any place of the report with expressions such: vars["values"].get("myFavoriteLocationCD");
Though it is important to note the dataset should be triggered by the report before these data elements.
The particular row you want to display you specify in a "Text" field inside your grid. Just drag and drop a "Text" field inside your grid. If you bound the fields you want to display to your grid, the "Text" field inside the grid inherits the bindings of its parent (the grid), so you can access the bindings automatically in the "Text" field.
You could try following steps, maybe that works.
Don't use "Dynamic Text" field, instead use a regular "Text" field
Ensure the fields of your query which you use, are bound to the grid (you sayed you already did)
Open the "Text" field
Change preselected pull-down entry "Auto" into "HTML"
Change preselected pull-down entry "Formatting" into "Dynamic Text"
Wrap your code in <value-of format="HTML"> your code goes here... </value-of>
Note: You should check in the "Expression Builder" of your "Text" field if you are able to access the fields you bound to the grid. If they are not available sth. went wrong with your binding. Avoid binding query records to cells this will drive you crazy.
If you want to display a list, ensure you didn't set a constant height in the row of your grid. Set the height to 100% than the row takes its height dynamically.
What about the idea to optimize your query, that only get the results you want are displayed, than you don’t need to filter them with java script? If you don’t need the filtered results in another place this would be the cleaner solution in my opinion.
I have a standard form in MS-Access which lists a bunch of orders, and each row contains order no, customer, etc fields + a button to view notes and attached document files.
On request from our customer we should gray out the button btnAnm (or check or uncheck a checkbox) depending on a calculation from two queries to two other tables (a SELECT COUNT WHERE and a check if a text field is empty).
I've tried btnAnm_BeforeUpdate(...) and btnAnm_BeforeRender(...) and put breakpoints in the subs, but none of them trigger. The same if I use the control Ordernr instead of btnAnm.
I'd like a function in the Detail VBA code to be triggered for each "Me." (row) so to speak, and set the row's control's properties in that sub.
What do I do? I've looked at the help file and searched here.
*Edit: So I want to do something that "isn't made to work that way"? Ie. events are not triggered in Details.
As an alternative, could I base the value of a checkbox on each line on a query based on the 'Ordernr' field of the current row and the result of a SELECT COUNT from another table and empty field check?
Do I do this in the query the list is based on, or can I bind the extra checkbox field to a query?
A description of how to do this (combine a COUNT and a WHERE "not empty" to yes/no checkbox value) would be perfectly acceptable, I think! :)*
You cannot do much with an unbound control in a continuous form, anything you do will only apply to the current record. You can use a bound control with a click event so that it acts like a button.
Presumably the related documents have a reference to the order number that appears on your form, which means that you can create a control, let us call it CountOrders, with a ControlSource like so:
=DCount("OrderID","QueryName","OrderID=" & [OrderID])
The control can be hidden, or you can set it up to return true or False for use with a textbox, you can also use it for Conditional Formatting, but sadly, not for command buttons.
Expression Is [CountOrders]>0
You can also hide the contents and add a click event so that is acts in place of the command button. Conditional Formatting will allow you to enable or disable a textbox.
As I understand your question, you have a continuous form with as command button that appears on each row - and you'd like to enable/disable the button conditionally depending on the contents of the row.
Unfortunately you can't do that. It seems that you can't reference the individual command buttons separately.
Having wanted to do something similar in the past I came up with two alternate ways of setting up my interface.
Put a trap into the onClick code for the Button. Which is icky, because it is counter intuitive to the user. But it gets you that functionality now.
Move the command button (and editable fields) up into the form header, and make the rows read only. Your users then interact with the record only in the header, and select the record they want work with in the list below. As I recall this is known a Master-Detail interface.
