View 5 RepliesWhen 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 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
I had a program that was working, then the underlying access database was changed and a few of the field types were changed from double to Decime. I went to the table adapter and tried to reconfigure the the table and adapters, but the underlying code that is generated by VB did not changed and cept the fields ad doubles and I was getting a null error.
I then deleated the table and added the table again using the same sql statements
I now can not view the desing view of the form and get the following error.
"DataMember property 'Specification_SPCUrethane' cannot be found on the DataSource."
How do I remove the binding sourse and detaset from the form so that it will display so I can fix the problem?
error in binding
Dadapter = New SqlDataAdapter(dat, conn)
Me.Dadapter.Fill(Me.Table)
bs.DataSource = Me.Table
DgvTire.DataSource = bs
txtserial.DataBindings.Add("text", Table, "serialn")
error: This causes two bindings in the collection to bind to the same property. Parameter name: binding
what should i do with this error?
i have two forms. first one is main form, and 2nd is product form. there's a button in the main form which, when clicked, product form should appear. the code is as follows
productForm.Show()
Me.hide()
then this error come:
" Cannot Bind to the property or column product_name on the DataSource. Parameter name: dataMember "
I did was add another table to an existing datasource so I could use one instead of two separate sources. Now I get this error.System.InvalidOperationException was unhandled Message="An error occurred creating the form. See Exception.InnerException for details.

but now i have another problem in datasource property that is i want to binding more than one table so that all table's data rows can be displayed in datagridveiw control. suppose i have two table as per order no..

In silverlight, can you bind to a property that contains parameter? For example, the following doesnt seem to work. Am I missing something or is this not possible?
C#
private System.Collections.Generic.Dictionary<string, string> ValuesField = new System.Collections.Generic.Dictionary<string, string>();

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 used the select disctinct statement with 2 fields from my sql database table. Here is my code.
myCommand = New SqlCommand("SELECT DISTINCT Author FROM tblBook UNION SELECT DISTINCT BookCode FROM tblBook",myConnection)
myAdapter = New SqlDataAdapter(myCommand)
myAdapter.Fill(myDataSet, "tblBook")
cboAuthor.DataSource = myDataSet.Tables(0)
cboAuthor.DisplayMember = "Author"
cboAuthor.DisplayValue = "BookCode"
and it generates error : cannot bind to the new member. Parameter name:value.

View 1 RepliesI 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

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. I have to close the entire program and reopen it before the changes take effect on my report. This piece is used to bound the report to the dataset

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?
