Is there a way to highlight an item in a VB.Net listbox without allowing the user to change selection?
When I set the selection Mode to "NONE" I canīt select an item in the code.
Same when I disable the listbox.
When we left click a grid cell, or list item, it highlights. Left click outside it and the selection jumps to the new place.
I can RIGHT click anywhere in the grid without disturbing an existing highlight, but I want it to work more like windows explorer would in terms of file selection..
i.e. if I right click inside the range, the range stays, if I right click outside the range, the range moves to a new single cell that I just right flicked.
Try it now on this page. Select some text, right click on the selection and it stays. Right click outside the selection and it goes. In datagrid (for example), the selection can only be modified with a left click.
How can we change this so the selection behaviour of a datagrid/list is more like this text pane?
On a related note. If I left click in a textbox I can drag a selection out. If i wanted to right click and drag the selection out, would it be the same process? (It's for a custom string manipulation picker control..)
I've got my first ever program and it's working. Having tested it a bit it would be helpful for the user to be able to copy the results printed in a listbox into an email or text doc. Just somewhere where they can make a note of it really.Is there something I need to do to enable it? All the google results I found were referring more to doing this in code. I literally want to be able to support Ctrl+A, the Ctrl+C straight out of the program to wherever the user wants.
View 4 RepliesSo - I have some text in an RTF control. I want the user to be able to highlight text and apply an attribute. The following code is placed into a button called BOLD and seems to work nicely:
If rtfText.SelectedText.Length > 0 Then
rtfText.SelectionFont = New Font(rtfText.SelectionFont, FontStyle.Bold)
End If
The code above will turn the selected text bold.
But then the user selects the Same text and with the following code placed into a button called ITALIC it removes the bold attribute and replaces it with italics.
If rtfText.SelectedText.Length > 0 Then
rtfText.SelectionFont = New Font(rtfText.SelectionFont, FontStyle.Italic)
End If
Since the users actions are separate - I can not know that they want BOLD and ITALIC, so how do I make sure I keep the existing attribute on the selected text (which, by the way could be part bold and part not-bold) and add italic?
Somehow I need to add the italic attribute to the selected text, not simply replace all attributes with italic.
I am new to vb and I am having so much trouble with this. What I need to do is this: I have a form application for winter sports equipment rental.I have a listbox filled with the equipment for the user to choose from then I have a combobox for the user to select the duration they would like to rent it. The book that I am using has no examples I can refrence and i have had no luck online either. I am posting what I have so far. However, i think I am going in the wrong direction. I have been working on this for so long that I think I have over thought it and made a mess of it. I am thinking that I need to add a new class for rentalRates then use enum of durationType and equipmentType but I am unsure how to move that way. That is using a enum, a 2d array and a parallel array? [code]

I have a combo box that has multiple options, when the user selects one of the options (world wide city destinations) a specific value is assigned to a variable. For example if "New York" is selected the variable "x" is assigned the number 155. What I want to do is output the destination that has been selected ie "New York" in a label called "lblOutput1", do I need to store the destination as a seperate variable to be able to produce it in this label as I cannot seem to get it to work:
At the moment I am using:
lblOutput1.Text = "bla bla bla " + cmbDestination.SelectedText + " bla bla bla " + Today()
I am using visual studio vb 2005 and I searched the forums for an answer to this but didn't find exactly what I was looking for. I am using the following code to populate a list box. What I want is to have a datagrid view show the results of a dataset that is generated when a user selects something from the list box. I know how to generate the dataset, but I'm not sure how to bind that to a datagrid view and I'm not sure what event I should use from the list box.[code]

I have a combobox on a form with the dropdownstyle set to drop down. Users can either salect a value from the list, or type in any value they wish. This all works fine. However, when one particular item in the list is selected I wish to set a different value. Unfortunately I don't appear to be able to set the combobox Text property from within any of the events that fire when the selected item is changed.

I'd like to force a user to make a selection from a combobox.I've tried to test it by Combobox.SelectedText = String.empty as well as another version similar to this but a little different.When I test it, it will tell me that it is still unselected/blank even when I selected something.

In my program I've got several comboboxes that all have the same comboboxitems and when the user makes a selection in one of the comboboxes the selected comboboxitem gets disabled in the other comboboxes. (i.e. If the user has selected the comboboxitem with value 'a' in combobox #1 and selected the comboboxitem with value 'b' in combobox #2 then in remaining comboboxes both the comboboxitems with values 'a' and 'b' are disabled)
View 1 RepliesI seem to be having issues with the selected index on a list box.
The list box is having various items inserted depending on the user selection. An example would be:
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "Item1")
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "AND")
[CODE]......................
This all work and displays without a problem. The issue I have is if I select the second of the two AND's. If I click the second "AND" in the list and then a button to fire a method, the selected index is always the index of the first "AND". Dim listIndex as integer = ListBox1.SelectedIndex
I can't work out why, the listbox itself will always show the second one as selected, but the action will happen against the first one.
I have just realised that ComboBoxes don't have a Change event. I have a combobox filled with a few items, eg. Bakery, Deli, Fruit & Veg, etc. Choose one of these items, all the related items show in the dgv. However, when I blank the text in the Combobox (press Delete key whilst Combobox has the focus), what event fires so I can blank the dgv? The combobox does not contain a Blank item. Even if it does, the Blank item only fires the ComboBox1_SelectedIndexChanged when the user scrolls down to, or clicks on, the blank value.
I want to clear the dgv when the user blanks the combobox without necessarily changing the selection index.

I have a program I'm trying to put together to allow my employees to submit shift reports. I'm doing this simply to make my life a little easier as this way, they will all be formatted the same. Instead of spending a large chunk of my afternoon thumbing through a bunch of differently formatted reports.
One feature that I need to figure out requires that one listbox can see what another is doing. Here, let me try to explain..
I have one list box that keeps track of EVERY action the employee does on a customers account. (cancel, upgrade, downgrade) and then a hidden listbox that JUST tracks "cancel" actions..one for "upgrade" actions and one for "downgrade" actions.
The reason behind that is that in the shift report, the all need to be listed separately. This way, I can just add each list to it's own array and list them where I need to.
The problem I've run into... If an employee handles an "upgrade" action at the beginning of the day..and then later on the upgrade is canceled, I can easily remove it from the main listbox that shows everything, however, I can't figure out how to find it in it's own listbox. The "Upgrade" box.

So unfortunately, on the shift report, it's still there even though it's gone in the program as far as the employee can see.The item in the main listbox doesn't have the same index as the item in each individual list boxes so I can't just tell it to remove the item at the same index..
