Readonly ComboBox
Mar 6, 2010How do I make it to where you cannot type into a combobox, but you can choose items through the drop down? I tried Readonly, but it makes it so you can't type AND can't drop down select.

So i made a code here that checks if the user inputs something else then what i want him to input.If it something else is found it returns the text back to "Hours(s)"

View 4 RepliesVS 2010 ReadOnly Combobox Without Making It A DropDownList?
May 10, 2010i have an app that has many suggest append comboboxes in the style of just straight dropdown.
I also clear the text in all of these draopdowns via resettext() in a loop when my user clicks a 'New' button
is there any way to either A:
make the combobox read only (without selecting dropdownlist)
or B:
allow suggest append to fire on all keystrokes instead of only when it sees a match in the combobox....
example: combobox1 contains the following items:
- apples
- oranges
- bananas
as of right now, if my user types in "pears" it won't see any 'P' and won't suggest anything else or even drop down the combobox and allow "Pears" to be entered and because my app does processing only on the items in the list, "pears" then throws an exception....I'm trying to force them to choose only the items in the list and not be allowed to enter anything else while still enjoying the clean look of a resettext() on a combobox

.net - Setting ReadOnly Property In PropertyGrid Sets All Properties Readonly?
Jun 12, 2012I am using a PropertyGrid control to edit my class properties and I am trying to set certain properties read-only depending on other property settings.This is the code of my class:
Imports System.ComponentModel
Imports System.Reflection
Public Class PropertyClass[code].....
This is the code I am using to edit the values:
Dim c As New PropertyClass
PropertyGrid1.SelectedObject = c
The problem is that when I set SomeProperty to True, nothing happens and when I then set it to False again it sets all properties Read-Only.

View 4 RepliesName A Property 'ReadOnly'?
Oct 20, 2009I have a user control and I'd like to give it a custom property named ReadOnly. I get "Keyword is not valid as an identifier", as it thinks I'm writing a ReadOnly Property named something.
so really I can call mine 'Read_Only', but I'm just curious if there's an easy way to get the other name in there, since then my control will be similar to the visual controls that have ReadOnly in the designer.

View 6 Replies.net - Backcolor Of Readonly Richtextbox?
Sep 23, 2010I have a winforms app with a series of textboxes and one rich textbox. Upon a button click I would like to set all the fields to being readonly. The only issue with this is that the background color of a readonly richtextbox is white as opposed to the grey used by the textboxes.
I have tried setting the backcolor property of the richtextbox to being Color.LightGrey but this is not the same grey used by the textboxes. I have also tried setting the back color to being the backcolor of one of the readonly textboxes but this does not work either. what is the best way to get a readonly rich text box that looks like a readonly text box?

View 2 RepliesCannot Update The Database Because Is Readonly?
Jan 24, 2011I had created a simple program that uses a MDF file as Database, this includes in the project 2 files: mgcdb.mdf and mgcdb_log.ldf, the program installs in C:Program Files(x86)CompanyNameProgramName, then when I try to update the database I get an error "Failed to update database because is read-only".
During testing on VB I had no problems, since the database was being use by "Authenticated Users group", but on Deployment the Users group don't have enough access to work with these files. So far I know or at least I think that what I need to do is to ADD access to the user, right? Since I didn't know how to do this I found this address [URL].. where it shows you an example on how to add/remove access to a file. I changed the module to this:

Datagridview Readonly Not Working?
Oct 30, 2009I have a form with a button and a tabcontrol that has 2 tabs, on each tab I have 1 datagridview in them
both datagridviews are bound in the load event to a different bindingsource each.
When I click the button I fill the datatables programatically, and set some cells and columns on the datagridview to readonly.
The columns are set to readonly on both grids, but the cells are not. Only the cells in the first datagridview are being set to readonly and the cell on the second grid are not.
Further info:
If before clicking the button i switch to the second tabpage on the tabcontrol, and click the second grid on a column, and then go back to the first tabpage, the readonly cells are set fine when I click the button
If I press the button a second time, the readonly cells are set on both grids are set fine.
It seems to me that this error is presented on non-active (in lack of a better name) datagridviews.
I have tried, to call update, refresh, focus, endedit, etc etc on the click event of the button for the second grid but nothing seems to make it work.

Make Non-TextBoxes Appear ReadOnly?
Mar 23, 2011Is there any way of making controls that aren't textboxes into readonly controls? Specifically I have a date time picker (but I have the problem occasionally with other controls), that I want to make ReadOnly as opposed to disabled so that the user can see clearly what is in the control but cannot edit it. Making a control like this disabled makes it hard to read and furthermore, gives the impression to the user that they are to ignore the field, which defeats the object.
I'm sure a suggestion will also be to stick the information into a text box, however there are other date time picker controls that CAN be edited in the same window, and it would make life a lot easier if the layout of each was exactly the same.
