Set Borderstyle Of A Datagridview Column At Runtime (.Net Framework 4.0)?

Dec 15, 2011

Before binding the datagridview to the datasource, I'm writing something like mentioned below but it's taking no effect. Assume the column in question is named DisplayName.

Populating DataGridView ComboBox Column During Runtime?

Nov 16, 2009

I've got a window with multiple datagridviews. Each with data from a separate dataTable. All of which are part of the same DataSet. There are a couple of places where one DataTable has a field joined with the lookup dataTable from the dataset. For example a lookup table for LugSizes has a field called LugSize that is also it's primary key. Another table called Device Terminations has a field called LugSize to which the user can only select those values from the LugSize lookup table. I thought it would be as simple as using the Items.Add method for the combobox column whenever a new lookup table row was added to its own datagridview. Unfortunately, when I try to initially clear the items list, the data error event is triggered for every row.

Here's a sample of my code if it helps:

HTML

Private Sub FillLugSizeComboBox()
Try
If colDTLugSize.Items.Count > 0 Then colDTLugSize.Items.Clear()

Putting A Value In A Cell Via The Column Name When The Column Is Added At Runtime?

Apr 25, 2010

I'm trying to create a datagridviewrow and add data to it at runtime. I want the row to have the cells correspond to the columns in a datagridview, so that when I add data to the cells i can call the column name (the columns are likely to change around, so i think the name is better to use then the index).I create the row using the following code:

Dim row As New DataGridViewRow
row.CreateCells(Datagrid)

and the column using the following code:

Dim col As New DataGridViewComboBoxColumn
col.HeaderText = "Reference"
col.Name = "Reference"
datagrid.Columns.Insert(0, col)

I would like to add data to the row via the following code (or something similar that uses the column name instead of the index:

arow.Cells("Reference").Value = Detail.Reference

However at runtime I get the exception Column named Reference cannot be found. Parameter name: columnName I have a sneaking suspicion that the cells cannot be accessed with the column name because the row isnt really attached to columns yet (the row hasnt been added to the datagridview yet. (I tried cloning the cells of a row and then adding them to the row but no success)?

C# - Column Sequence And The Entity Framework?

Dec 28, 2009

So, when you bind a collection of Entity objects to a grid component, the grid displays those fields in the sequential order they are found in the SQL Table they came from. This shows that the ordinal position of the fields are associated with their corresponding entity properties... somehow or other.

So here is the question: How can I obtain the table field ordinal position by reflecting over an Entity Framework Entity's properties? Let me tell you what I know and what I have tried. Apparently, each data field property in an EF Entity is decorated with a System.Runtime.Serialization.DataMemberAttribute. This attribute appears to have an Order property. However, I have discovered that this property does not contain what I am looking for. The value for all Data Properties in an Entity seems to be -1. What ever order is, it isn't ordinal position.

C# - Entity Framework Looking For Wrong Column

Mar 12, 2011

I'm brand new to the Entity Framework and trying to learn all it can offer. I'm currently working my way through the MVC Music Store tutorial which includes the following code:

public ActionResult Browse(string genre) {
// Retrieve Genre and its Associated Albums from database
var genreModel = storeDB.Genres.Include("Albums")
.Single(g => g.Name == genre);
return View(genreModel);
[Code] .....

The problem is I'm getting the following exception:
Invalid column name 'GenreGenreId'.
Which I know is true, but I can't for the life of my work out where it's getting 'GenreGenreId' from.

Here is the source for my classes:
Album.vb
Public Class Album
Private _title As String
Private _genre As Genre
Private _AlbumId As Int32

Datagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?

Feb 13, 2012

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?

Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

Show Bit Column As A Checkbox Column In Unbound Datagridview

May 14, 2010

Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp

Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.

I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.

how can i change this in code at runtime

Upgrade The Framework On The Server - When Run The .exe File From The Server,get A Runtime Error?

Jun 29, 2009

I have several programs that I wrote in Visual Basic.net 2003 that I run from a server at work. We upgraded to Visual Studio 2008 recently and I converted my code to that version. I rebuilt the .exes and tried to run it from the server. It said I needed to upgrade the framework on the server, which I did. Now when I run the .exe file from the server I get a runtime error:

Runtime Error!
Program: d:...
This application has requested the Runtime to terminate it in an unusual way. Please contact the applicaiton's support team for more information.

These programs are very important to the day-to-day operations of the company I work for. I did backup the software before converting it, so we're running normally right now, but there are modifications and upgrades I need to make as soon as possible, but cannot due to the programs crashing when I run the on the server.
