ComboBox - How To Resize Dropdown Area Based On Item Length

Jun 11, 2011

Since we have to resize the combo box dropdown area based on the combo box item length, used the drawstring() to add items to combo based on the item length. This gave us the below issue: On moving the cursor on the drop down area the font color and the background color are back hence the text is not readable (i.e. the whole item becomes black).

Below piece of code is used to achieve this,
Private Sub cboClient_DrawItem(ByVal
sender As
Object,
ByVal e
As System.Windows.Forms.DrawItemEventArgs)
[Code] .....

We tried changing font color and the dropdown area backcolor on selecting a particular item. How to make the text readable (i.e. the font color should change while if we scroll on the item).

VS 2008 Check To See If Item Exists In A List?

Jan 6, 2010

see if an object is already in a generic List(Of T) than the way I am currently doing it? The way I do it at the moment is like so:I have a method that I call each time I want to check to see if an object exists in the list (if it already exists I do not want to add it again) and the list to check is passed in to this method along with the item that should be added to it:

[Code]...

So as you can see this function just loops through the list that was passed in and if the DisplayName property of one of the items in the list is the same as the ProgramName argument that was passed in to the method as well then it returns True to indicate that this program is already in the list.I thought about using a Predicate with the List.Find method but cant see how I would get it to work because that predicate method will not have any way of referencing the list (its a method local list, not class level)

Mouse Cursor Is Hiding Until Item Selected From Dropdown List

Jun 8, 2012

VB.NET Winforms Application... When a user starts typing in the search box of the application it automatically populates the name list dropdown box with the valid results and sets the droppeddown value to true... Everything is working fine except the fact that the user is forced to select a value from the name list or press the esc key because without doing so the mouse cursor just disappears and you have to move the mouse all the way outside the application for it to come back and it will only do so while outside the applicaiton.. Below is the code that I am using for this and it should be noted that I am using the droppeddown value else where in the application and none of those instances have an issue its only this one..

Private Sub u_lastName_Box_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles u_lastName_Box.TextChanged
u_nameLook_Box.Items.Clear()

Removing Multiple Selected Rows From DataGridView That Is Binded To List(Of T)?

Dec 8, 2011

I have a datagridview binded to a list of objects... I have a column named Selected containing a checkbox. When these checkboxes are checked and a button is clicked, I want those particular rows to be removed. I initially set it out to iterate through the grid's rows and RemoveAt(SelectedRowIndex) but of course when it removes an object from the List of objects at the selected row (IE Row 1, 4 and 6), the list indexes change and it fails to work properly when it goes to remove the next row since Row 4 is now row 3 in the list...? What is the best way to do this?

Change List Of Combobox A Based On Item Chosen From Combobox B?

Jun 17, 2011

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.

Possible To Make List Box Item Height For Item Depending On Amount Of Lines That Item Contains?

Jan 1, 2012

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

Sql - Dynamic Dropdown Based On Radio Selection

Nov 2, 2009

We have a GUI that displays a radio selection box (3 options) that are the three sites where our hospitals are. We need to dropdown located on the form to fill with only the locations based on the selected radio option.

Here is the code behind we have so far (sorry, VB)

[Code]....

For the record the Location dropdown is currently databound but its a static SELECT statement which brings us all the locations but we'd prefer it to be cleaner if it only returned the locations based on Site. We are using Visual Basic 2008 Express Edition for development.

VS 2008 - Item Exists In Listview?

Sep 9, 2009

I am filling a listview control with a big number of items but i came across an problem, the repeated values. In those items i use .Text and .Tag so i can relate some hidden values per item.

ComoboBox DropDown Select One Item And Display Another

Apr 17, 2011

I am not sure how I could achieve this: allow the user to select a value (string) from the dropdown list of a ComboBox and display another value in the editable text. The user can modify this displayed value as well. In VB6 I had a combobox where the list property contained a two dimensional array. When the user selected a value from the dropdown list, the displayed value was set using the second dimension of the array. Something like this:

Writing To File And Selecting An Item Using A Dropdown Box?

Mar 27, 2011

My program that I'm creating is a quiz creation tool, based for teachers to create quizzes and then use them to aid with quizzing their students.I've got the whole program working in that you can create quiz, play the quiz and then see how many questions were answers correctly and how many questions their were The problem I'm having is that I don't know how I can save multiple quizzes, for example you can create one quiz, that then saves as a .txt in debug however, when you then create another quiz and click the save file the old quiz details are sitting in the .txt

Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim filename As String 'full file/path name for QuizRecords.txt
Dim index As Short 'loop control variable

[code]....

So what I'd like it to do is, when saved create another text file? Or another set of data questions, I have been looking through my Computing projects in Visual Basic . NET book as well as through online but I can't find anything that I understand as such.
