BindingSource.Find (Multiple Columns)
Oct 1, 2006
I have a bindingsource that is connected to a table where tho fields determine uniqueness. During a refresh I would like to return to the row that the user was on when he clicked the refresh button. BindingSource.find only supports one column in so far as i have been able to infer. So how doi do it. Altering the table is out of the question. Besides searching on multiple fields is a common event. Like for example first and lastname or perhaps company and journal number.

For a WinForms VB.Net application, I use the Bindingsource's filtering capacity to filter data, which is seen in a DataGridview. The BindingSource is from a DataSet, created using the Designer, and the data comes from a Access DB, using JetEngine and .Net 3.5. So basically:
Datagridview.Datasource = xxBindingSource
xxBindingsource.Filter = "[extended filter string with multiple columns]"
This filtering works fine, however, now I included some extra columns in the DataGridView, which I'd like to filter on, too. Of course, when I feed the manually added columns to the Filter of the BindingSource, this doesn't work out.I've done some research, and was not able to find any way to use the BindingSource's filtering syntax on the DataGridview. I'd like to use this syntax though, as I designed quite a nice UserControl and class around it, to provide smooth, fast and simple filtering capabilities.

All fields from my class objects are added to the columns collection of DataGridViews, when the forms or custom controls that contain them are viewed within the VS 2005 designer. I haven't been able to figure out how to stop the designer from auto-adding all of the fields found within the bindingsource object.

I'm trying to use the bindingsource.find method to match a datarow column with a user entered text. I know that using BindingSource1.find("columnName", searchString) will work when the user enters the exact string. What I would like to know is how to find a row that is close to the string using a wildcard search... a good example I guess is:dim searchString as string = textbox1.text 'lets say the user enter "se"dim index as integer = myBindingSource.find("columnName", searchString) 'I would like to find the firs record that starts with "se"I can achieve the idea using the bindingsource.filter method but this will interfere with other parts of my application if the bindingsource is changed.

In my application, I have a single table. Two of the fields in the table are COUNTY and CATNUM. Both are string.
I want to perform a FIND on both fields. I have no problem doing the search on CATNUM alone IF I set a FILTER first. Due to the size of the table, it takes a few seconds to set the filter. Once the filter is set, .FIND works quickly.
The customer has the option of setting a filter to work on one COUNTRY at a time. If they choose to do so, no problem.
If they don't have a filter set and they are using the entire table, then when the customer wants to search for a COUNTRY & CATNUM, I present a list of COUNTRIES in the table and a textbox for them to input the CATNUM.
Now I have the COUNRTY and CATNUM - how do I do the FIND? I already know that I can FILTER the table by COUNTRY then do the find but as I said before, it takes too long for the filter to be set (in my mind anyway!).

So I got this DB and I have these values
Hash | Value
abcd | "test"
efgh | "test2"
I want to search my db for the value abcd, so I wrote this Private Sub Button1_Click_2(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click MessageBox.Show(Me.Table_0BindingSource.Find("Hash", "abcd"))
End Sub
but I keep getting -1 even if there is no data that matches what I want to search.
How can I do a search using Data Sources?

I've got a databound query in my application which is querying the "Customers" table in our database.I've created this directly from the ComboBox's datasource creator in the Design view.Various bits of code created in the designer include:
Me.CustomerBindingSource.DataSource = Me.CustomerDataSet
Me.ComboBox_Customers.DataSource = Me.CustomerBindingSource
What I've done in the first stage of developing this feature is to show my users a ComboBox showing a specific subset of the customer list by applying a filter to the BindingSource.
Me.CustomerBindingSource.Filter = "someColumn = 3"
What I want to do on a second pass is to allow the users to type a specific bit of information into a textbox and check whether it appears in Me.CustomerDataSet like so:
Dim x As IEnumerable(Of CustomerDataSet.customerRow) = From cust In Me.CustomerDataSet.customer Where cust.custno.Trim = "test"
If x.Count <> 0 Then
At this point, I have a customerRow object. I want to check whether this customerRow object appears in the list presented to users in Me.ComboBox_Customers via the filtered Me.CustomerBindingSource. Me.CustomerBindingSource does not (directly) contain customerRow objects, it contains Object objects.How do I find out whether Me.CustomerBindingSource contains the customerRow object at whatever lower level?Also Once I've determined that Me.CustomerBindingSource contains the item, how do I select that entry in the ComboBox?

I have a strongly-typed datasets created using VS data designers. In this dataset I have 3 main tables:
Patients
Users (Relationship: Users.ClinicianId > Patients.ClinicianId)
SchedAppointments
Issue is I would like to filter the datasets based the user type and a few other ways. How can I filter each table(sql query) using the BindingSource that was automatically added. I thought I read that some of the functions work against the current datamember, so I tried the following code.
WAMMTPTrackerDataSet1BindingSource.DataMember = "Patients"
WAMMTPTrackerDataSet1BindingSource.Filter = "ClinicianId = " & gClinicianId
'Users
[Code].....
It appears that what I read was either very old or never worked that way. what is the best way to handle with with a typed dataset?

I'm binding a DataGridView to a BindingSource to a LINQ IEnumerable, I found that the BindingSource.Find method throws an exception because .Find isn't implemented in IEnumerable (and the BindingSource just passes the call to it's DataSource). I need to use BindingSource.Find to select/highlight a particular row in the DataGridView.
Is there a feasable way to extend my DataContext to support this behavior w/o breaking anything else? I expected to find the code out there already, but I've searched exaustively with no luck.Without it, I cannot "move" the BindingSource using .Position and that's a pretty common use of the BindingSource I think.

How can I set up my WPF datagrid to sort on multiple columns similar to having two sortable columns, clicking on the header of the first column for a primary sort and then SHIFT clicking on the header of the second column for a secondary sort. I would like the multiple column sort to happen automatically when the user clicks on the header of the first column without having to SHIFT click on the second column header. Is there a way to do this entirely in the xaml? If not how can I do this in the code behind? Currently using VB.Net but a C# snippet is acceptable if you have one.

I have 3 related tables in a DataSet - Customers, Products and Orders.I am trying to create an "editable" DataGridView which, ideally, will contain columns from all the tables. I have tried creating the joins in the TableAdapter SQL, but this results in a read-only data grid.
Customers and Orders are joined in a 1:M relationship by CUSTID.
Products and Orders are joined in a 1:M relationship by PRDID.
When the user adds a new Order record they will key the ORDERID, CUSTID, PRDID and QTY.I would like the DataGridView to display the related CUSNAM and PRDDES as soon as the user has keyed the Order record.The data must be displayed on a single data grid row. I am not interested in drill down or multiple data grids.My data looks like this:
Orders: ORDERID, CUSTID, PRDID, QTY
Products: PRDID, PRDDES
Customers: CUSTID, CUSNAM
The data grid should look like this:
ORDERID, CUSTID, CUSDES, PRDID, PRDDES, QTY
My SQL would look like this:
SELECT Orders.ORDERID, Orders.CUSTID, Customers.CUSNAME, Orders.PRDID, Products.PRDDES, Orders.QTY
FROM (ORDERS
INNER JOIN CUSTOMERS ON Orders.CUSTID = Customers.CUSTID)
INNER JOIN PRODUCTS ON Orders.PRDID = Products.PRDID;

I have put my business logic in a partial class as suggested in best practices. One of the conditions is that one of four fields of a row has have a value. Setting the errorprovider has no problems when creating a new row in the new row event. All the textboxes in the form show the error condition.
Dim ErrorString As String = "A value is needed for at least one of the " & vbCrLf & "Gallon, Fuel, Oil, or Misc fields"
e.Row.SetColumnError("Gallons", ErrorString)[code]....
The logic that sets them back to a no error condition though only sets the currently focused control in the form to no error. When the error is corrected.
MyFuelRow.SetColumnError("Gallons", "")
MyFuelRow.SetColumnError("FuelCost", "")[code]....
How can you reset multiple column errors at once?

I am making a application that manages room availability in a building.I have seen a similar function in another application that I'm trying to duplicate. I want to have a control, which I assume is the DataGridView that shows the room numbers on the left hand side, and then on the right it shows a box in that room numbers row for every day that the room is occupied. If it is occupied for more than one day, the box is joined.What control are they using? How do I link one row cell across multiple columns?
