Preserve all items after selecting with multiselect widget - streamlit

I want to preserve all items after selecting from multiselect widget. For example, with this code:
values = ['a', 'b', 'c']
st.multiselect('test: ', tuple(values), key='1')
after I select ‘a’, the option left to select is ‘b’ and ‘c’. Is it possible to preserve all items (‘a’, ‘b’, ‘c’), after selecting one?

I want to add data below the last value of row a. (pygsheet)

sh[9].append(values=[claststr], start='a8')
This code adds a column.
I want to add a value to the next column with the last value of row 'a' or 'b'.

you can use
wks.append_table(["claststr", None, None, None])
Or you can use
wks.update_value( (1,len(wks[0])), "classstr")

Filtering table via Query builder - null value not selecting all

When my drop-down "filter" has no value selected, my table displays zero records. I need it to select all values.
The table is tied to Datasource1 containing fields:Name, Status, Team1, and Team2. I have a second Datasource called Teams that contains team names. I setup query builder for Datasource1 to change based on a radio button(status) and a dropdown(teamFilter).
Datasource1 - Query Builder:
status= :status and (team1 = :teamFilter or team2 = :teamFilter)
Selecting a value in the drop-down properly filters the table. The issue is when no value is selected, or if I select the null option.

Dynamically update SQLite row based on column values

Is it possible for SQLite to dynamically insert/update values in the row of a table based on other columns within that row? Best illustrated with a simple example
CREATE TABLE family(first TEXT, last TEXT, full TEXT *magical specification);
INSERT INTO family (first,last) VALUES ('foo','bar')
And have the table automatically fill in the third column with a combination of the other two:
first last full
--------- ------------ -----------
foo bar foo bar

You could use a trigger:
CREATE TRIGGER family_full
AFTER INSERT ON family
FOR EACH ROW
WHEN NEW.full IS NULL
BEGIN
UPDATE family
SET full = first || ' ' || last
WHERE rowid = NEW.rowid;
END;

A GridColumn having columnEdit set as RepositoryItemComboBox , on changing SelectedItem, Old Item persists

A gridCoumn is defined in a Devex Xtra GridControl(winform type).
This column has two properties set :
FieldName --> a field name of a column in dataSource. OptionType
ColumnEdit --> as a RepositoryItemCombobox object , this object's 'Items' properties is having two value : Option1 , option2 & option3.
When data is set at runtime , the GridColumn shows the respective values in 'OptionType' column.
But now i cant change the values in any combobox of this column to other option by using the dropDown.
What am i missing ?????

Asp.Net MVC 3 ListBox will not select initial values

I am trying to set the initial values for a list box using asp.net mvc 3. It does fill in the options, but doesn't select them.
Here is my code. This attempt uses a hardcoded set of values
#Html.ListBoxFor(Function(model) model.PageTags, New MultiSelectList(Model.PageTags, "ID", "TagEn", New Integer(){1,2})
I have also tried an example that I would expect would select all the values.
#Html.ListBoxFor(Function(model) model.PageTags, New MultiSelectList(Model.PageTags, "ID", "TagEn", Model.PageTags)

You have to pass the selected values as an enumerable of "values" (and not an enumerable of the original "items"). In your case this should be a list of IDs. E.g. to select all try to pass the selected values like this: Model.PageTags.Select(i => i.ID)
