I searched and only found how to sort combobox variables through the Properties sidebar. This will not work for what I'm trying to do.
I have a textbox where the user will type in a name. They click the Add button, and the name is added to the combobox options. Let's say I add "Bob" then "Andy" then "Carl". In the combobox it would list them in that order.
I need to use a button that will sort these names alphabetically. How would I do that?
Instead of changing the "Sorted" in properties to true, I set it so that when you click the button, it would do this. So the "Sort" button code would look like this:
ComboBox1.Sorted = True
Put them in an array and use Array.Sort then back into the combobox

In my form,i have a list of employees in a combo box and i need to map some employees to particular department.I need to change the combo-box to List box.Scenario is as follows,
1. List A contains all employees.
2. If i click 'Add' button the selected employees must move to list B
and list A must contain remaining employees
.
I searched for List box but i couldn't find in extjs4.
Is there any example or link for multiselect listbox in ext-js4?
Thanks
There is no built-in ListBox widget in ExtJs4. However, Ext.view.View may become an listbox after some manipulations.
Here is an example of such a tuned View. Demos may be found here, here and here (this one looks like just what you need).
You can create two such listboxes and the "add" button. Then assign handler to button which would remove selected item from the first listbox's store and add it to the second's store.
is there a method of setting up my datagridview to show me textboxcolumns until editmode is entered? At which time I will swap some textboxcolumns for bound comboboxcolumns. And at the end of validation/exit edit mode I can swap back?
If there's a method of doing this please share some links to examples.
I wouldn't try to switch DataGridView ColumnTypes like that. Sounds like a bad time.
Is your goal to have a DataGridViewComboBoxColumn that does not display the ComboBox dropdown button when it's not being edited? If so, there are two options:
Set the column's DataGridViewComboBoxColumn.DisplayStyleForCurrentCellOnly property to True.
Create your own DGV column based on the ComboBox by extending DataGridViewTextBoxCell. MSDN has a great article for doing this with the Calendar control here.
Of course you can. In the properties of the datagridview you can drill down to the column proprieties and switch the datatype to combo box. Very straight forward and easy.
I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.
Thanks a lot!
Take a look at SelectedValueChanged. You can subscrive to this event on your first combobox, then when the event is raised, you can combo2.Items.Clear () the 2nd collection, then add your items.
i have created a dynamic table through vb.net, so htmltable, htmltablerow, htmltablecell.
I have added all style and properties in there. so eg.
dim td as htmltablecell
td.style.add("width","100px")
td.style.add("color","blue")
now what i want to do is add the tag to each row. this is because the first td of every row is a checkbox. and then textboxes follow. So when anyone clicks on the textbox, i want to checkbox to get checked.
Any idea how I can do this?
Your question is near incomprehensible, consider revising?
td.style.add("color","blue") now what i want to do is add the tag to each row
Since your table is dynamic, to add more styles and properties onto htmltablerow, you would do just as you did with your htmltablecells.
So when anyone clicks on the textbox, i want to checkbox to get checked. Any idea how I can do this?
You're looking for what is called the on_click event for the textbox. Programatically, when this event is triggered, you check your checkbox. Here's an example with a on_click in a textbox.
I have a CheckedListBox with a few items and I want to allow user to select more than one using arrows keys or mouse clicks combined with shift and ctrl keys so I set SelectionMode property to MultiExtended.
In design time it is not possible I get an error:
value property is not valid.
and if I set it in runtime by doing:
clbEmployees.SelectionMode = SelectionMode.MultiSimple
I get an error too:
CheckedListBox is not compatible with multiple selection.
How could I do this?
It's not supported for the CheckedListBox.
However, I'm fairly sure that you could mimic that functionality in a ListView. Just look at the CheckBoxes and MultiSelect properties of the Listview. As far as I can tell from the documenation those are compatible.
This might be too late, but I just put my solution here; Works perfect for me:
1- Just leave the CheckedListBox Selection mode as "ONE' in property sheet.
2- in your code, loop thru the checked item in your checked Box using the checked item property as following:
For each XX as 'DataTpe' in CheckedListBox.CheckedItems
'Here you assign each checked item to wherever you want to direct to'
