Error - Cannot Bind To The Property Or Column ALERT_NAME_NEW On The DataSource

Jan 14, 2012

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."

C# - Cannot Bind To The Property Or Column Site On The DataSource.{10}Parameter Name: DataMember

Sep 18, 2010

When I try to use the following line of code:

I get the following exception:

EXCEPTION : Cannot bind to the property or column Site on the DataSource.{10}Parameter name: dataMember

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.

Feb 28, 2011

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

VS 2010 Dynamically Bind Datasource To ReportViewer

Jan 19, 2011

I have a ReportViewer showing a report that is bound to a dataset. The dataset gets its data from a Access database backend. I have a separate form that allows the user to add/update/delete data. My problem is when the user makes changes to the data using the data entry form, the report does not reflect those changes.

.net - Bind To The Enabled Property Of A ToolStripMenuItem

May 31, 2012

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?

.net - Why Does This Code Not Bind SelectedItem To A Property

Oct 7, 2010

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.

Wpf - Bind The SelectedValue Of A ComboBox To A Property?

Sep 27, 2010

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)...

VS 2008 Items Collection Cannot Be Modified When The DataSource Property Is Set

Feb 13, 2010

I have two tables "Person" and "Alias" in a one to many relationship. I have a DGV for "Person" and want to use a combobox for the Aliases. I also have a textbox and a button for the user to type the alias name and click the button to add the alias name to the combobox and update the dataset. I keep getting the "Items collection cannot be modified when the DataSource property is set." Error. But if i use a DGV instead of a combobox for aliases, I have no errors and everything works fine. If I remove the datasource property for the combobox it will not get populated with the data already entered, so how, or can I, set it up where the combobox gets populated when the form loads and able to add items to the combobox????
