DisplayName DataAnnotations Not Working In WinForms 3.5 DataGridView?
Sep 7, 2011
I've used DataAnnotations attribute DisplayName successfully using MVC model binding, and even with WPF/Silverlight model binding and of course it works just fine, but now I'm on a project that I'm forced to use VB.NET 3.5 WinForms.
I have a Linq2Sql model and I created a partial class for one of my classes and included a MetadataType attribute to point to a metadata class. I added a DisplayName attribute to a property in the metadata class. I then bind my datagridview with an IQueryable(Of mydatatype), but the column name in the grid is the Property's name and not the DisplayName.
Am I missing something? Is there something else I need to do to get the datagridview to use the DisplayName?
In my Model class:
Imports System.ComponentModel
Imports System.ComponentModel.DataAnnotations
<MetadataType(GetType(vwREVIEW_ECRMetadata))> _

I have installed the same service multiple times with different ServiceNames and DisplayNames. OnStart I want to parse the ServiceName and/or the DisplayName and use that to set a configuration for the specific service iteration. The point of this is to be able to have many services using the same code in the same directory, but connecting to different databases. Then I update one exe, one place and it gets all services up to date. Problem is, I can't find a way to get these details out of the system.

I am trying to enumerate the
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall
registry key and check the displayname & displayversion registry value for all the sub keys under the uninstall key then compare the displayname & displayversion value with a if statement.
For example if one of the the displayname = "Adobe Flash Player 10 ActiveX" & displayversion = "10.1.82.76" then textbox.text = "Your adobe flash is up to date"
This is the code I been using to check a specific registry value to see if quicktime 7.67.75.0 is installed i figured it would be best to enumerate the subkeys and check the displayname & displayversion because im checking like 6 programs to see if the version is current.
Dim quicktime As String
quicktime = My.Computer.Registry.GetValue _
("HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall{EB900AF8-CC61-4E15-871B-98D1EA3E8025}", "DisplayVersion", Nothing)

i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...
that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below.

I have a vb.net function which uses oledb to create a spreadsheet, then treat it like a database, creating tables and inserting values. The function takes in a filename and a dataset, and returns the filename if it worked. The function works beautifully on my dev machine, but not other PCs. Below is my function, is there anything wrong with the code? EDIT: There are no errors being thrown, the resulting file doesn't contain any data.

Alright I have a DataGridView, where the user can click on the column headers to sort. When they add a new row while a sort is applied, the record isn't created until the moment they validate the row(which they cannot do till they exit the newRow). How can I make the row be selected once it is sorted?The DataGridView is databound.The selection mode for the grid is full row.I'm using VB.NET with SQLite database backend.I suspect I need to use the RowsAdded event, or DataBindingComplete events. The records in question do have a unique GUID attached but it is NOT visible in the DataGridView.

I have a few classes, one is a form, the other is the source of the datagridview. I want to be able to sort the columns of the datagridview by clicking on the header. Here are the classes that I am dealing with:
Imports DiscoveryByte.AddTools.Misc_Tools
Public Class ViewDiscoveryFlashCards
Private DBBindingSource As New BindingSource

I have a WinForms app that has a DGV that's bound to a BindingSource and when the user clicks on the new row line @ the bottom I would like it to fill in two columns values automatically but I'm not sure which event is fired when that row is switches to user editing mode.

I have a Windows Form VS2010 .NET 4 project with a standard DataGridView bound to a datasource on a form.
The grid has a text column that I want to be a point and edit at the character clicked to. Like normal textbox/editors when you click on the character you want to adjust. If possible I would also like to use the UP/DOWN keys to move between rows but would like the cursor to move to the same character position obviously in the same column without selecting the entire text.
I have tried a few things:
DataGridView1.ClearSelection()
DataGridView1.BeginEdit(False)
The BeginEdit just puts the cursor at the end of the text, which means another click to point to the character position for editing.
I know a Commercial grid like DevExpress defaults to editing in which you can click to the correct character position with one click but obviously costs money.
I have tried in the DataGridView1_EditingControlShowing event
If TypeOf e.Control Is System.Windows.Forms.DataGridViewTextBoxEditingControl Then
Dim tb As TextBox = e.Control
tb.SelectionStart = 5
[Code]....
I am just trying to remove the two or three clicks to get to the character position that needs adjustment.

I'm using a DataGridView in VB.Net in VS 2005. The issue is, when there are rows that exceed the width of the DataGridView, the horizontal scroll bar doesn't appear (the ScrollBars property is set to "Both"), but an ellipsis appears at the end of each row that is too long. I don't want the ellipsis, but the horizontal scroll bar. The vertical scroll bar works as expected when the number of rows exceed the height of the DataGridView.
I have tried setting numerous related properties (changing the AutoSizing property of the DataGridView, Resizability of the Row Template, made sure that no Columns were Frozen) to no avail.

I have a windows form with a DataGridView control.I bound it into an attached DB file (.mdf).I perform insertion by generating a dynamic Insert statement. I then pump this sql statement into a SqlCommand object and perform ExecuteNonQuery() method. All of these is performed by handling a Button click event. The button and the gridview is located on the same form.
Public Sub InsertRow(ByVal param1 As String, ByVal param2 As String, ByVal param3 As String)
Dim strConn As String = (the connection string)
Dim sqlConn As New SqlConnection(strConn)
[code]....
After the code execution, the DataGridView is not updating (remains intact). I have to exit the form and reload it to have the updated gridview.For certain reasons, I can't use DataTable object.But I would like to have this gridview updated everytime I run the insertion.

I have a DGV I am working on, and I have many columns.
For example I have Columns colIsDayOff (Checkbox), colStartTime(Time), colEndTime(Time)
What I need to do is if when my DGV loads the data if colIsDayOff is checked, then make the value of the Start and End time columns blank, invisible, or something.

I can edit values on the DataGridView and as long as the program is running it is there exit the program and restart the program and return to the DataGridView and all changes are gone. I know there has been a lot of posts on this subject and I have read many of them but nobody seems to be using SqlClientCE for the data base and I need instructions of how to make a table adapter say like the following do the trick.[code]...

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.

I have an unbound checkbox in my datagrid view along with other bound fields from a dataset. I do not need to send back the checkbox status to my dataset or the DB. Instead I will loop though the DGV and look for those checked and do another process with them after its done being loaded. The problem is this. When I check a checkbox, then check another, the first one goes back to unchecked and so forth, back and forth. There is no add, update or deletes needed for this DGV.

i have a windows forms app which displays a bunch of records from my sql database. when i modify records in the grid and click on save, all changes are saved EXCEPT the changes made to the currently highlighted row. they aren't written out the database until i exit the actual program, despite clicking on my save button.so for example, if i change 5 different records in the grid, and click on save, and then click on refresh to reload the data from the database, 4 out of the 5 are saved correctly, but the row that is currently highlighted (meaning, the last row i changed) still has the old data.My code for the save button look like:

I'm using vb 2005, seems sorting is not working if I change the data by code. For example, if I have a simple form with only one datagridview and one button, grid was sorted on column 1, then I press the button to randomly change data in column 2, then use column 2 to sort, the display order is not correct, but after the button click, if I click on a cell, the grid will re-sort by itself, and get the right list. I know DataGridView is not for Editing data...

But if CurrentCell is on new row and I click to delete row - it's deleting that row that is standing before current selected cell. It means that dgv.CurrentRow.IsNewRow is not showing is realy currentRow new or not! But why? Old VB version? I am using VB Professional 2008

Basically this code works for the first column of the DataGridView. It sort of stops iterating after the last calculation of the row is performed and doesn't change the cc value at all. Meaning the loop gets stuck after the first iteration.

I have some code written by another developer(no, really). The datagridview has the AllowUserToResizeColumns property set to true, but at runtime the grid will not allow column resizing. I've checked the code to see if the property is being set in code and I can't find anything. Is there some other grid property that, if set to a certain value, will disable column resizing?
