Cannot Bind The Property To The Column
Jun 12, 2012
I'm trying to display the serial number of the 'recipient' you selected in a textbox but I get this error:
System.ArgumentException: Cannot bind to the property or column RecipientSNo on the DataSource.
I did this to another textbox with a different query (same codes, just changed the column name from 'recipient' to 'issuer') just to debug and it works! I tried it again to the 'recipient' but it still doesn;t work.My code:
query("SELECT RecipientSNo FROM Recipient WHERE CONCAT(FirstName, ' ', MI, '. ', LastName) = '" & ReceiverName.Text & "';")
Try
adapter = New MySqlDataAdapter(CommandText, ServerString)
table = New DataTable
[code]....
I just coped this code and changed the textbox and column names and it did not work already.. What seems to be the problem? I double checked my table and column names already.

I have the following code on a form:
Public Sub Init(ByVal SelectedItems As List(Of Cheque))
Items = New BindingList(Of Cheque)(SelectedItems )
BindingSource1.DataSource = Items
[code]....
This code gets called like so:
...
fmEdit.Init(myList)
fmEdit.Show()
All variables are populated etc, it seems to go through the DataBindings.Add ok but when the form appears I get the error about unable to bind to a property or column called Id. I tried replacing the DataBindings.Add code to use the BindingSource1 instead of Items but I get a similar error.The names of the properties in the class match that of the name in the Databindings.Add code.
UPDATE: Here is my class:
Public Class Cheque
Public Id As String
Public Status As Byte
[code]....

I created a master - detail form . I changed the name of one datacolumn in the dataset (not the source) from "alert_name" to "alert_name_new" and i saved all files.I checked the file <dataset>.xsd in the directory and i found the change was made... as expected.When i try to run the application the following error message appears: "Cannot bind to the property or column ALERT_NAME_NEW on the DataSource."
Note: I use vb 2010 express edition

When I try to use the following line of code:
cboSite.DataBindings.Add("Text", _dtSite.Select("Site <> 'ALL'"), "Site")
I get the following exception:
EXCEPTION : Cannot bind to the property or column Site on the DataSource.{10}Parameter name: dataMember
details I am connecting to an Access database and using .net 3.5 and writing the code in VB. In this database I have a table named Sites with a column named Site and when I try to use the line of code above I get the exception noted. I was under the impression that I could explicitly name the column that I need to use in my control (combo box).

I'm trying to do the following for asp.net combobox:
Text='<%# IIf(Eval("Name").ToString().Equals(""), Bind("Other"), Bind("Name") %>'
What I'm trying to do is if the "Name" column is empty then bind to "Other" column, otherwise bind to "Name" column.

I'm trying to do MVP where I have a view specific model that the presenter manipulates and the view binds to. There is no other connection between the presenter and view (the view fires off commands to the domain model via a gateway type pattern).
As you can guess, this makes the ability to bind to any property of any object really important.
I'm having trouble finding the correct way to bind to the Enabled property of a ToolStripMenuItem. Most controls have a .DataBindings property, but this one seems to lack it. I haven't found much info online about how to do this. Is it even possible?

I'untangle a particularly malodorous collection of spaghetti code. Anyway, I have the following XAML code:
<UserControl.Resources>
<CollectionViewSource x:Key="XMLObjectGroups" Source="{Binding Path=XMLObjectList}">
<CollectionViewSource.GroupDescriptions>
<PropertyGroupDescription PropertyName="IsDateType"/>
[code].....
On the second line XMLObjectList is a readonly property of a ViewModel class, returning a Collections.ObjectModel.ReadOnlyObservableCollection(Of MyOrder).On the final line SelectedOrder is a property of the same ViewModel class, which allows setting and getting of a MyOrder object.
I have confirmed that XMLObjectList is being correctly referenced by renaming the property, mistyping the string, breakpoints, etc. XMLObjectList definitely references the XMLObjectList property of this particular ViewModel class.The SelectedOrder property, however, is never accessed at runtime, meaning that it isn't properly hooked up to the SelectedItem of this ListView.

I've got a ComboBox with an ItemsSource which I've bound to a List(Of String).What I'd like to do is have the XAML update a String property when the SelectedValue of the ComboBox changes. I've seen a whole bunch of examples for TextBoxes which use
Text="{Binding Path=MyString}"sort of stuff, but I don't really think that'll be the way to go if, in future, I need to change the ItemsSource to a List(Of ObscureObject)...

I would like to know if its possible to bind the property LOCATION of an object like button.[code]So that, every time I move either the hscrollbar1 or vscrollbar1 the button1.location will change or moves the object to the location of hscrollbar1.value and vscrollbar1.value. It should happen without setting its value using the SCROLL EVENT.

But I'm having a problem with showing the right info in a gridview.
Basically I've got a maintenance tool for an application. And I want to make it multi language.
This is a check for the language:
'setting the column name where to get the text resource from
Dim comment As String = "comment"
If (licentie.getlanguage() = "NL") Then
[Code]....
So far this works. But in my template I've got the following code in the gridview:
<asp:Label ID="LabelType" runat="server" Text='<%# Bind("Comment") %>' />
How do I set the column 'comment_NL' when the language is set 'NL' in the bind?

There are issue with using WebBrowser late bind calls related to object/property names generation.For example:
WebBrowser1.Document.DomDocument.Forms.Myform.mycontrol.Value = "test"
will fail with more than one instance of the WebBrowser control.what actually happen is that mycontrol object become Mycontrol and compiled vb.net application will fail with error
Member not found. (Exception from HRESULT: 0x80020003 (DISP_E_MEMBERNOTFOUND))
at Microsoft.VisualBasic.CompilerServices.LateBinding.LateGet(Object o, Type objType,
String name, Object[] args, String[] paramnames, Boolean[] CopyBack)[code].....
Same code will work with vb6 app with multiple WebBrowser controls
Edit: This code is comipled with: Option Strict Off

VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

I have a Datagridview with a bound datatable in it. Then I add a check box column to it.
When I click the headder of the DGV, it sorts the bound columns, and clears all checked checkboxes in the checkbox column.
How do I bind the checkboxcolumn to the rest of the table?

In the control template for the custom control, the control is wrapped in a border that's background is a RadialGradientBrush with gradient stops. one gradient stop's color is bound to StartColor and the other's is bound to EndColor. I have this WORKING in XAML, but I need to convert it to VB code. The border element of the control template in XAML is done with the following code:

it's possibly to bind the values in a combobox to a column in a dataset? If so, how would I go about doing it? For example, If I have a column named 'Names' in a DataSet, each comboBox item would be a name from that column.(There will only me at maximum, 10 entries)

I'm trying to populate the list of a combobox by binding it to a datatable. Also, I want the selected value of the combobox to be bound to an object property so that when the selected value changes, it's automatically updating the object. However it's causing an error at runtime: "This causes two bindings in the collection to bind to the same property.
Parameter name: binding" I thought binding the dropdown list to a datatable and the selected value to an object were different properties but obviously I'm not getting it right.
Code:
Private Sub PopulateSiteSelect()
With Me.PlanSiteSelect
If _Plan.PlanID <> Nothing And _User.UserID <> Nothing And _Plan.Category <> Nothing Then
