In an Access combobox CB I place in CB.value Clt, a string known to be in the dropdown list. Not by typing but by VBA code assignment.
I want to ensure than the dropdown list is on the same value.
I've tried CB.recordset.movenext in a loop until I hit Clt, but this does not move the dropdown list. I've also tried CB.Recordset.FindFirst using an SQL like clause. This also does not move the dropdown list.
How can I do this?
Thanks for any insight.

When user select master checkbox all values must be push to array. Value must splice from array when user unselect specific checkbox and push again to array if select again. Here is my sample code in stackblitz. Thank you in advance.
There were a few mistakes in your code, notably that you didn't check for the correct property on the MatCheckboxChange event. You checked for the check property, when it is actually called checked, see here.
Also you tried to use splice with a string (the name property of the current row) and number argument, when in fact it takes number, number.
A proper IDE would notify you of these mistakes and help you solve them.

I have a combobox which has an array of Strings such as "Alice", "Bob",and "Charlie". After user presses the ok button I want to remove all the elements in the combobox. How do I do this during run time ? All I know is to manually right click on the combobox and remove its element one by one.
Thanks.
Settings String[] to an empty array will clear the strings stored in the Combobox, but will not clear the active value visible on the front panel terminal. To clear that as well, use the "Value" property with a blank string.
Here's a snippet:
After having tried many ways this does clear elements but the first element is not removed completely.
We are using slickgrid in our angular directive.
And we would like to use another list directive (simple select element with input) in a cell/column of Slickgrid.
I want the list element to be visible when the grid is available, so user knows there is a list. Therefor I am using the list directive as formatter. It Is visible when the grid is rendered.
The Problem:
When the cell that holds list element is clicked, the editor mode is never fired because of the list element click event.
We thought to use an image of list that user knows there is a list, and when clicked open the list.
Is there a better way to do it?
We have managed to get it done using list directive as our rendere/formatter as well as editor.
We made our list directive as ReadOnly so it does not fire click event. And now one sees a list element when grid is rendered. And when one clicks on the cell with list, the list is automatically opened via code. The only problem we have now with this solution is that how to copy selected Item from editor to formatter (if anyone knows, please share).
Any better solution is also welcomed.
I have a question to ask you.
I want to make a menu updatable using a value of a int variable (If the value of the variable changes are also modified the menu items). I know the possibility to update the string of a single menu item when its is clicked (by the creation of a function in signal connect() that update the single string of the menu item), but for the first case i don't have find nothing in internet for now!
Thank you!
Just do it.
You don't need to wrap a simple integer in all the GTK+ object and event machinery; if you know when the value changes, you can just compute a new label text for the menu item and set it (using gtk_menu_item_set_label()).
I have a Source ComboBox to populate source fields (25-30 items) shown below in first page
"A"
"B"
...
"Z"
I have selected last item from ComboBox as shown below
"Z"
and when traversing to the next page after saving, i need to make the source combo selection blank, so i have return the below code to reset the Source combobox to point to first item (to reset the display to start from top of dropdown list for user selection)
// my first value in source List is empty space - “”
sourceComboBox.setValue("");
even if you use below code snippets like
sourceComboBox.getSelectionModel().selectFirst();
sourceComboBox.getItems().clear();
sourceComboBox.getSelectionModel().clearAndSelect(0);
but when i click open the combobox dropdown it still shows dropdown display from bottom as shown below
...
"X"
"Y"
"Z"
I am unable to post images for representing combobox values, so has put in above examples.
This looks like a graphics bug to me or am I doing something wrong?
I have seen similar issue reported in below question but no work around suggested so far
Combobox clearing value issue
If you want to simply "reset" the combo box, I think all you have to do is set the value to null, like so:
sourceComboBox.setValue(null);
I ran into nearly the exact same situation and came across your question while looking for a solution. Fortunately, I came up with a workaround that forces the ComboBoxes to reset. When you reset the data on your pane, instead of doing something like:
sourceComboBox.getSelectionModel().clearSelection();
sourceComboBox.getItems.clear();
do something like this...
parentNode.getChildren().remove(sourceComboBox);
sourceComboBox= new ComboBox(); // do whatever else you need to format your ComboBox
parentNode.add(sourceComboBox);
You'll also need to do a setItems() again on your ComboBox so the new one will be populated. This is not an ideal solution but it seems to be working as I expect the provided clearSelection() method would.
Below is the code you're looking for. It will reset it to whatever index you give in within the parenthesis.
sourceComboBox.setSelectedIndex(0);
Goodluck
Most of the things were giving me an error when I tried them. What worked best for me was to use this
comboBox.getSelectionModel.clearSelection();
This will essentially set the value of your ComboBox to null. Because of this, if you are referring to the value of the ComboBox in another place, it becomes important to check for whether the value of the ComboBox is null using this
if(comboBox.getValue() != null)
//Code segment here
The ComboBox control has not a method like scrollTo(index) of the ListView. So it seems hard to workaround that behavior. You can issue a feature request at JavaFX Jira.
