Set A Row READONLY?
Oct 25, 2010
I am trying to set the an entire row readonly if one of the fields is set to true. I have a checkbox on column 6 which is either ticked or not. Therefore, if the checkbox is ticked i.e., set to TRUE then the entire row should be READONLY.
Dim irowDatePaid As Integer
For irowDatePaid = 0 To DgvReturns.Rows.Count - 1
If GetBool((Me.DgvReturns.Rows(irowDatePaid).Cells(7).Value) = True Then
[code].....
The row is set to readonly fine. However, in 3 columns I have checkboxes which are not set to readonly. Is it possible to set enable = false for these checkboxes..

I 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.

I 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.

What ever happened to the readonly method in the ComboBox? So i thought if MS did not have that option let me code around it. 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)"

How 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.

I 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?

It seems that VB.NET and C# readonly keyword have some differences... Say, a ReadOnly property in C# can be assigned in some conditions, but in VB.NET - never?

I 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:

I 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.

Is 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.

how to make DataRows in a DataTable ReadOnly? You can set DataColumns ReadOnly, but not DataRows?
I'd like to bind a DataRow ReadOnly property to my DataGridViewRow ReadOnly property. So when my DataGridView displays the underlying DataTable, if the DataRow is ReadOnly then the DataGridViewRow would automatically be ReadOnly as well. how to do this other than the way I do it below?
For Each r As DataGridViewRow In Me.dgvCurrent.Rows
If r.Cells("curAnalyteID").Value <> Me.cbxAnalyte.SelectedValue Then
Me.dgvCurrent.Rows(r.Index).ReadOnly = True

It seems that in the following example, TestProperty() and TestDouble() are functionally equivalent. Is the case? I usually use Property/Get when I have a single line "Return Variable_" type of "function", and Function when I have a more involved thing going on. Is that reasonable?
