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.

I am trying to filter a subform based off a value selected in a listbox.
My list box is called cboCurrentListName and this is populated using a select query
The subform is called Form_subform_ListContents
For the change event for the list box I have the following code, however no filters are applied when its executed.
Me.Form_subform_ListContents.Form.Filter = "[ListName]=" & Me.cboCurrentListName.Value
Me.Form_subform_ListContents.Form.Filter = True
I have also tried using Master/Child links to execute this using the following steps, but this caused an input box to pop up when the fom loaded:
first I set the 'link child fields' option in the properties of the subform to 'ListName' (this is the field name that populates the list box and is present in the subform
then I set the 'link master fields' option in the properties of the subform to 'cboCurrentListName' (the listbox name)
then in the listbox properties I set the control source to 'cboCurrentListName'
The above steps cased an input box to pop up on opening the form (the value typed in here does filter the subform). However I don't want an input box in order to do this, I want to use the listbox.
I have googled this and fried different methods but have had no luck. I am pretty new to access and of the control source sections aren't a strong point of mine, which is why I tried to use the VBA on the event change instead
Any help would be appricaited, I tried a few things and had no luck.
EDIT: When trying the master/hild option I also get an error 'Can'y build a link between unbound forms' if I click the 3 dots in the poperties. SO for the above steps I had to manually type in the otpions.
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?
Listbox 1 contains names of hairdressers and Listbox 2 contains services provided by all of them then in Listbox 3 both the selected hairdresser(only 1 allowed) and and selected services are contained. There is a remove button which removes items from Listbox 3. I want a code for the button that if a hairdresser is removed all services also get removed otherwise only services are removed.
For Each str As String In Hairdresser.lstHairdresser.Items
If Not lstHairdresserAndServices.Items.Contains(str) Then
lstHairdresserAndServices.Items.Clear()
Else
'more code here but above statement never gets true
End If
Next
If the hairdresser is always the first item in the 3rd listbox, all you have to do is check if the selectedindex equals 0. If so, clear the listbox. Otherwise just remove the selected item.
Alternatively, you could search the the 1st listbox for the selected string. If found clear the listbox otherwise remove the selected item.
It is also possible to mark the listbox items when you add then to the listbox. Set the tag property to something like "hairdresser" or "service" and when the remove button is clicked all you have to do is check the tag property.
Finally I would recommend a different approach: Instead of adding the items to the listbox, fill a data structure with the hairdresser's name and services, display this structure in the listbox and when the remove button is clicked compare the selected item to the structure to find out what was selected.
I have a combobox that is filled with Site names. When an item is selected, the user is able to edit the site information. If they modify the name of the site, I want to update this in the combobox list. I have seen that I can remove the item, and re-add it, but I don't want to change the order, I only want to change the text of the selected item.
Is there an accesseser that allows the text in a combobox list item to be modified?
I am using telerik's rad combo boxes (dropdowns) on my aspx page. there are 3 rad combo boxes and they are cascading dropdowns. the items in the final dropdown is dependent on the selection of the 2nd dropdown.
Now, i had to insert a "select all" option in the final dropdown. this being a static value, i added it using "appenddatabounditems" property of the rad combo box, setting it to be true. I can now see the select all option, but the items in the dropdown list are repeated. I have used the distinct keyword in the query. Also, when i make another selection in the 2nd dropdown box, the values in the third dropdown are appended i.e they show "Select all" + items of the previously selected 2nd dropdown option + values of the currently selected dropdown selection.
Am i missing something in the query? or there is something wrong with the telerik controls? or the ajax manager?
PLease help.
Thanks,
ghanshyam.
Are you using the EnableLoadOnDemand="true" setting to perform the cascade? The combo box does not clear the old items out automatically. Two things you can do:
Delete the old items OR
Bind the entire list to the combo box and hide the invalid ones. This has worked for us when the list is relatively small.
HTH.
