Asp.net - Make Enum Bindable To Datagridview
Dec 10, 2009
I have an object which contains a number of string properties and an enum property called CRAction.
I have another object which represents a collection of the above object.
When I bind the collection object to something like a gridview, all of the string properties bind fine, but the enum doesn't appear.
I have added another string property which returns CRAction.ToString, but is there a better way to make an enum bindable to a control as part of an object?
It all seems a little hackish to have another property for the same thing purely for data binding!

I have a URL lets say . some time i need to send HTTP and some time i need to send it to HTTPS for that i created a enum:
Private _protocol As Protocol
Enum Protocol
HTTP
HTTPS

public Enum ClaimStatus
Ongoing = 0
Completed = 1
[Code]....
With code above, how do I assign the value to the combobox while retrieving data from the table so that it point to the corresponding combobox item. For example, if the value of status_ID is 1 then the combobox should show "completed" in the datagridview.

I would like to make an enum of strings. There are several masks for text boxes that I would like to standardize in our system.For simplicity lets say there are 2 masks:
"PhoneNumber" which is "(999)000-0000"
"Zip Code" which is "00000-9999"
I would like to be able to reference these through out the entire program in a manner such as:
DefaultMasks.ZipCode or DefaultMasks.PhoneNumber
Since enums can not be of string type, what would your best suggestions be as to how I could do this. I had thought about a class with constants in it but I was not sure how to implement that properly.

I cannot get Bindable LINQ to work with VB.NET for the life of me. How do I get the .AsBindable extention to appear?
[code]...
Imagine I magically come up with a collection full of items. I'll stry something like the following
DataContext = From G In TheList.AsBindable Order By G.Name
But I get an error on .AsBindable that "AsBindable is not a member of TestList"

I'm trying to declare an enumeration and one of the names I'd like to use for an item is not usable apparently. Where I am declaring 'STEP = 3', I get this error message in visual studio: "Statement cannot appear within an Enum body. End of statement expected." Is it possible to use STEP as an item name somehow? [Code]

As a coding exercise, I would like to know if it is possible to build a bindable data structure that would have a dynamic collection of field objects, in which each field not only would have a specific data type, but also would hold the value for that field. That is, is not like a DataTable where you can have many rows, I only want to manage a single collection of values.

Our shop primarily use "ADO objects" (I'm referring to DataSet, DataTable, and DataRow) for marshaling around data and manipulating it on forms and in grids. We are experimenting with creating shop-flavored counterparts to the native ADO objects so that we can impose our in-house standards on top of them. Implementing this is straightforward with one exception: I want our objects to be bindable to controls.
I'm aware of IList, IBindingList, BindingSource, etc. and have looked at and experimented with these, but I am falling short when it comes to making a class with no hard property names bindable. The native ADO objects are not strongly typed by default. You have column values that you access via the Item property (e.g. row("Age") or row.Item("Age")). The binding examples I've found online deal with strong-typed objects (e.g. row.Age). Essentially, we want to create custom ADO objects (not inherited from the native ones) that still retain their ability to bind to controls. In a grid I would expect to see columns Name, Age and Occupation from a row where these properties are exposed via row("Name"), row("Age") and row("Occupation"). This must be doable as this is exactly what the native DataTable and DataRow provide.

Which is better, using a nullable enum or adding the value None=0 to your enum list?Using nullables requires more code, but I kind of like it since it forces me to think about the possibility. Otherwise I'm liable to forget about the None enum and fail to account for it being a special case.

I am using VS2008 and I have a form which has a datagridview. This is for an invoice where I already have the user select the customer from a details view and want to have the items in the datagridview change based on what the customer selected. Then when the item is selected I want to have the price change accordingly.
So far I have the customer selction as well as the item combobox(not limited to cust items yet) appear, but I cannot figure out how to get the join of the 2 items (cust+item as the price varies from cust to cust) to change the price. Question is, is it possible to do this in the same datagridview, or should i try to just break this down some other way?

More for interest than actual need.is it possible to have an automatically decreasing enum in C# or VB.NET?
public enum testEnum
{
this = -1,
that,
other,
}
So that that = -2 and other = -3.I'm pretty sure the only way to do it is to specifically assign "that" and "other", but I wondered if there was an automatic way of doing it.
Edit To be clear, I'm simply talking about the automatic assignment of the value, not the actual value of the enum decreasing.

I'm using vb but still learning it. Here is the question, I have following ENUM created so that i can use it all the form. I created this Enum on my main form (startup form) and want to use in another form.
Enum MyStatus
Good = 1
Bad = 2
Normal = 3
End Enum
Now from other form I'm using it like frmMainmenu.MyStatus.red. I was wondering how i can make it public or create it in a way so that i don't need to give the prefix frmmainmenu before using its value.

How do I do this C# statement in VB.Net (2005):MainMap.MapType =(MapType)comboBoxMapType.SelectedValue;MainMap only accepts Types so passing the Integer value of the type is not possible. The combo contains a list of strings:comboBoxMapType.DataSource = Enum.GetValues(typeof(MapType));In my case I need to limit the list to less than 100% of the Enum values so code similar to .Datasource= code will not work.So in general I need a way to return an enum given the name of the enum.Maybe I should just do a Collection of Enums (if that is even possible) and use the name as the Key?

I have a DataType (text, numeric, date, boolean, money) enum and I need to put that in a file. How should I call the file and where in my DataAccessLayer.Generic namespace should I put the file into? Right now the file is called enum.vb and is in theDataAccessLayer.Generic.DataTypes namespace. The Result is ataAccessLayer.Generic.DataTypes.DataType, but it is misleading because the file is called enum.vb

In vb.net, I got an Enum defined As Integer:
Enum enUtilityTypeDetailStudentEntryWorkflow As Integer
enUTDSEW_Default = 379
[code].....
This works but it adds a lot of noise to the code and it seems like the Enum is already defined as an Integer, making me think, why do I have to assign it again?

i have a list as an enum and when I want to select values as following, what is the best way to approach it
Public Enum ScanLocations
station1 = 1
station2 = 2
station3 = 3
station4 = 4
end enum
So if i have "station2" as a value in a textbox etc, and I click a button 'next' then it will give me "station3"if i click 'previous' then it will give me "station1"

I have a DataGridView control and I want to know if the user has changed any data in the row when they leave one row and go to another row. Here's what I've done...
In the Form Class I defined a Before and After row image as follows:
Dim rwBefRow As New DataGridViewRow 'Before row image
Dim rwAftRow As New DataGridViewRow 'After row image
[code]....
At this point, when I look at rwBefRow, it contains the data in the row AFTER I make them.It's like when the RowLeave event fires, it also fires the RowEnter. I put a breakpoint at the RowEnter event and it gets control only when a row is entered, as you would expect

I know this is a proper enum:
Private Enum Months
JANUARY = 1
FEBRUARY = 2
...
End Enum
However, I want to have an enum where the string will solely be integers.
Example:
Private Enum ColumnCounts
01 = 5
02 = 4
03 = 40[code].....
Essentially, I didn't want to put the f in there, just wanted to do 01. The way this will be called is:
Select Case (nRecordType)
Case "01"
...
Case "02"[code].....
Because I'm not making an instance of it and not calling a constructor, there's no way to autopopulate a Dictionary.And I don't want to convert to integer so I'm not going to do an array. That is just in case eventually the value gets above 99 and the next value would be A0.I'm trying to think of easy future changes to this and backwards compatability.If you need more explanations, let me know.
Edit 2:This is what I've done now and I think it should work:
Public Class Part
Private Shared columnCounts As Dictionary(Of String, Integer) = New Dictionary(Of String, Integer)
Public Shared Function ValidateColumns(ByRef lstFiels As List(Of String)) As Boolean[code]....
I can't verify that it's going to do what I want to, but it doesn't give me an error when I build it so I'm crossing my fingers.
