In FillDataGrid() is where I'm doing he binding - datagridview1.datasource = BindingSource1 - and adjusting the columns size, row colors, etc. What is happening is the following: the last item added to BetsL is being repeated in the datagridview, the other items doesn't appear. If I have 4 items to display on it, it only shows the last item repeated 8 times
I'm converting one of my projects with Option Strict On, but I get a failure which I can't seem to solve.
Option Strict On doesn't allow late binding:I'm loading a combobox with a particular field from a .sdf. When I select a value from the combobox it loads other values from the sdf, but I get the error when Option strict on.

I want to use property bindings under application settings to store settings for my program. However I have run into a problem. For some reason the checked property is not binding to drop down menu item's checked state. The binding works for text boxes and other controls. I have tried to bind both using the checked property, and checked state property. Auto check on click for the menu items are set to true.
Anyone have any recommendations in getting the app-settings property binding to work without the need to manually set that info and manually run My.Settings.Save?

I don't know what's wrong, i can only move the 1st item but the second and so on doesn't make any changes. It remains in a listbox.
I've come across some strange behavior. I have a control that binds to a property like so:
<HyperlinkButton x:Name="ProjectBeheerLink"
Visibility="{Binding IsBeheerder, Converter={StaticResource VisibilityConverter}}"/>
In my viewmodel I have the property implemented like this:
Public ReadOnly Property IsBeheerder As Boolean
Get
Return iwtApp.AllMyFunctieRollen.Any(Function(x) x.Rol.Equals(Constants.RoleBeheerder))
End Get
End Property
Then when I raise my PropertyChanged event in my callback method
Private Sub GetMyPersonCompleted(ByVal lo As LoadOperation(Of FunctieRol))
'Init FunctieRollen ect. ...
RaisePropertyChanged(Function() Me.IsBeheerder)
End Sub
my binding does not update. However! If I implement a backend field like this:
_isBeheerder = iwtApp.AllMyFunctieRollen.Any(Function(x) x.Rol.Equals(Constants.RoleBeheerder))
RaisePropertyChanged(Function() Me.IsBeheerder)
And change my property like this:
Public ReadOnly Property IsBeheerder As Boolean
Get
Return _isBeheerder
End Get
End Property
Everything works fine...
I have a VB 2008 application with multiple DataPicker fields. The data is binded to SQL database. On the form load I set the checkBox for each date to false if there is no date in the field. Noticed that if I make changes to some dates for record 1 in the table, save it and scroll to the next record - I see the date that I just changed for record 1 - also on records 2 and 3. Why is it happening? I don't have that problem if I use text fields to display the dates. I had encountered the same problem with different project and just switched to text boxes. With this new project?

So i have that code in my xaml and the button gets filed with a list of string. Depending on what the users chooses on previous Usercontrol that item will be filed with differents items. The problem is if the user select one option at the first run the button will be filled correctly but if the user go back and select the other option the control doenst update and shows the same as before.. My english is not the best but i think i could made me understand! PS: the bindind on Button is to a readOnly property so i cant define it to Mode="TwoWay".. i took a look on the debug and the property ExportFormat gets updates with the new items but the usercontrol still displays the first option!!

VS2008 targeting .Net 3.5x. I have a combobox with a datasource and display member set, and when I run the project, I see the items. I am also binding the selected item to another object which contains the item upon which I want to select. I have verified that both the bound object and its underlying data contain the value I expect. The problem is that I cannot get it to select the correct item - it only ever selects the first item in the list.

I've bound a collection with public properties that are of type double to a datagridview control. If, in the datagrid, the user enters a value that is a string I get an error thrown, and I can't seem to find the method to handle it.
The only way I've been able to fix this is to make all public items in my bound collection of type string, and in the get/set make the private variables double.
This is a huge pain; is there any way to do this in a more elegant fashion?
2nd question is there a way to make the default header text something other than the public property name? (I know I can manually change this in the code later, I was wondering if there was a way to automatically have it something else)
(below is example code; I've changed the P property to reflect that change I had to make)
Public Class clsPIDElement
Private _P As Double
Private _I As Double

I have a grid populated from a list. Now there are particular properties in this list that I don't want displayed on the grid. It displays all of the columns perfectly, then adds 2 others I didn't originally have on the grid when I constructed it in designer mode. I have removed them after the binding with DataGridView.Columns.Remove("ColumName"). However, is there a way to prevent it from adding these beforehand, or is this the only way?
View 4 RepliesI have a datagridview with a column made of comboboxes. Is it possible to bind them to the result of a query? I've been able to do that, but I need to bind each combobox to a different query, or better to the same query which is called with a different parameter.
So, I have column1 which is made of combos. The user selects an item, and in column2, which is made of combos as well, I get some items which are taken from a query where the parameter is the value the user selected in column1. After that, I have column3, made of combos, in which each combo is populated with values resulting from a query with 2 parameters: one is the value selected in column1 and the second from column2. And this should be for each row.
I've been able only to bind the combos of column1, which are all populated using the same query. I thought I could use an array of tables where the i-th element of the array has the table (populated by my query using the table adapter) which contains the element of the combo in row i. Is it possible to bind the combo in column_j and row_i to that table?
I have a bit of code which loads data from a stored procedure in MS SQL Server and then loads the data to a datagridview, which works fine.

I developed a windows forms app, using VisualBasic in VS 2010. In my form, first I declared a variable as DataTable (Dim VarTable as New DataTable).
Second, changed the DataSource property of my DataGridView (DataGridView1.Datasource=VarTable)
Third, I filled the VarTable in this way: using a resulset from SqlDataReader, i added row by row.
Dim Result As SqlDataReader=CommandSQL.ExecuteReader
Do While Result.Read()
Dim RowToAdd As DataRow
RowToAdd=VarTable.NewRow()
RowToAdd("Code")=Result("Code")
RowToAdd("Name")=Result("Name")
VarTable.Rows.Add(RowToAdd)
Loop
Fourth, after the user changed data in datagridview, I saved the data back to SQL, cleared VarTable (VarTable.Rows.Clear()), and back to top of form to accept a new code. But here, problems begin. When I execute again the whole code described, the datagridview dont show the entire rows, and sometimes crashed with different errors. Solution? Dont fill VarTable row by row. Use VarTable.Load(Result) to populate the VarTable. I don't know why now works, But just I wanted to share this information.
