Specify A Custom Select Query For A Datatable Fill Method?

Dec 17, 2009

VB.Net 2005 SQL server 2005

I have a project I have a dataset that contains tables In the dataset designer, each table has a defaiult FILL command set. I have draged and droped my table as a grid onto my form VB automatically sets up the table adapter, and binding source to make it all work.

in my code, is placed in the form load routine, a tableadapter.fill(dataset.datatable)

Here is my dilemma. The data in my table may have 100's of thousands or rows.

I have presented the user with a front end that allows for filterring and selecting based on several columns. reguardless of how many rows the result set contains, there will always be the same columns in the dataset.

Because there are so many combinations of select query, i do not want to make 20 or 30 custom fillby's in the dataset. I want to make an addhoc select query and have the binding source and table adapters work as expected. I have created a query called "FillByCustom" in the dataset designer attached to the DataTable Adapter section.

My question is this.

If i build a select query that returns the desired rows, how do i place it into the adapter in place of the FILLBYCUSTOM select command, such that it all works as expected?

Datagrid Control - Fill And Use Each Datagrid Indepentent From Each Other?

Jul 22, 2009

I have on my form two datagridviews that correspond to the same table. They are both databound. They have been created automatically through dragging them from the datasources windows.One is datagridview and the other datagridview1. When ever I navigate through a datagrid the corresponding row on the other grid changes as well. I do not want this. Also I want to be able to fill and use each datagrid indepentent from each other. To fill a datagridview on load I use this code

Me.AllServicesTableAdapter.workstation(Me.Database2DataSet.AllServices)This code does not let me choose which datagrid to fill.

Avoid Closing Of A Custom Combo Box Popup Window In A Custom Datagrid?

Jan 31, 2012

I was trying to block the closing of a custom combo box popup window in my custom DataGrid. The popup window comes by pressing F4 or ALT+DOWN keys in my datagrid which is getting closed if I press the down arrow for the first time, after showing the first value in the combo box as selected. Next time onwards, if I press the F4 key and down arrow, I can move to any item in the popup window and select the item using keyboard and in that case, the popup window is not getting closed till I press the ENTER key or selection using the Mouse. Is there any specific reason for this behaviour or something is missing in my code part? [code]...

Fill Combobox With Database Query?

Apr 28, 2010

I am having a problem with filling a combobox with unique values.Im not very good at vb either so I will explain what I have done so far.

1. I added a combobox to my form called Combobox1

2. I clicked the little triangle widget thing on the ComboBox1 set the dataset to MyDATASETDataSet1

3. Display Member: CurrencyCountry, Value Member: FCode, Selected Value = None

4. I fill MyDATASETDataSet1 when the form loads using:

PricesTableAdapter.ComboBoxQuery(CurrencY_DATABASEDataSet1.Prices)
ComboBoxQuery =
SELECT DISTINCT [CurrencyCountry], [FCode] FROM [Prices]

The form does not load, i get the error: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.If I replace ComboQuery with Fill Query (which is the default fill command) it displays results....but not unique results, i see the same items being repeated throughout the list in the combobox.I guess my questions are:

1. when you fill a dataset do you need to select all the fields when you are creating your query?

2. if i simply wanted to perform the following lookup:

SELECT DISTINCT [CurrencyCountry], [FCode] FROM [Prices]and set the combobox Display Member: CurrencyCountry, Value Member: FCode how would I do this in the code?

3. how can i change my query to display only unique values, distinct doesnt seem to be working?

Sql Server - ExecuteScalar And SqlDataAdapter.Fill Behave Different For Same Query?

Jul 8, 2011

I have a big stored procedure that I run. At the end its supposed to select a singe value to say if it succeeded or not, so I run the query as

Dim Command As New SqlCommand(SqlString, Conn)
Return Command.ExecuteScalar()

Which works. However there is an error in my stored procedure. I know its causing an error because the logic in the stored procedure rolls back the transactions, and after the Execute Scalar call, my transaction count is down to 0 and the my data hasn't changed. However no SQL exception was generated.

The strange part is, I changed the code to grab all the result sets from the SP to see if I could get more information. So I called the same SP like this,

Dim DAObj As SqlDataAdapter = New SqlDataAdapter
Dim CommandObj As SqlCommand = New SqlCommand(SQLString, Conn)
DAObj.SelectCommand = CommandObj
Dim DS As New DataSet()
DAObj.Fill(DS)

When I run this, with the exact same sql as before, executing the exact same stored procedure, this time I get an SQL exception because one of my nested SP calls was missing required parameters. So what could cause this? Why would running it one way produce an error and the other way have the error but not report it? Is the difference on purpose, or some kind of obscure bug in ADO.Net?

Table Adapter FIll Causing Error With Combo Box (Query)?

Jun 2, 2009

I have the following query that executes when my form loads. It's the rowsource for my combo box. The query is fine and populates the combo perfect, however, when i click into the combo box I cannot click out of it or even close the form. I have tried taking out the line of code that fills the form via table adapter on load and it works fine (opening the form unbound by the main table). Has anyone run into this before? I have another combo box on the form setup the exact same way and this is not happening. I've experimented with different datatypes etc....

code to populate combo box:

Public Shared Function LoadCallSource() As String
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and Settingsdiw07My DocumentsDaily Backupsphone memo backend.mdb"

[code]....

If I take out the line

Me.MemoTableAdapter.Fill(Me.Table_Memo.Tables("Memo"), intMemoID)

The Combo boxes do not act up or "Lock"

Datagrid And Query : How To Use AND Statement

Nov 30, 2010

In my Form1 i have a datagrid with coulmns: CarName , CarModel , CarColor , CarOwner (there are a lot of data).

I added queries (textboxes that the user writes in text) that can "filter" data when the user want to choose specific CarName or specific CarModel.

textbox1 = CarName
textbox2 = CarModel
textbox3 = CarColor
textbox4 = CarOwner

If the user writes text in TextBox1 then the data shown in the DataGrid is filtered.What if the user want to choose also (!) a carOwner? I know how to use AND statements, but if the user didn't specified a carOwner non of the data is shown although there are this kind of data.

VS 2010 - DataGrid Custom Class Array

May 14, 2012

I am working on a project which lets the user edit the students in a certain group using a datagrid. First I created a class called student and then I created a student-array. Displaying the students in a datagrid works fine. On form-load, I change the datagridview.datasource to the student-array. The datagrid has 20 rows by default (Public dbstudebt(0 To 19) As student). When I edit an existing student everything works fine but when I fill something in in an empty cell and press enter or tab to confirm and add a new student, it just clears the cell and nothing happens. So basically, editing existing studs in the datagrid works fine, making new student doesn't work at all as those cells are always cleared immediately.

Datagrid Inside MdiChildren NOT Applying Custom Format?

May 24, 2012

I have a datagridview (windows forms) that is inside an mdiChild form. The custom format is given by a "for" instance, something like this:

For row As Integer = 0 To .Rows.Count - 1
If .Rows(row).Cells("someNumber").Value = 0 Then
.Rows(row).DefaultCellStyle.BackColor = Color.DarkSeaGreen
End If
Next

So, for every row in the grid that you find, if ther value in the "somenumber" =0 paint the whole row green. Problem is, if I put the form OUTSIDE of the MDIParent - just put frmMyform.show() in my btn that calls the form-, the grid WILL apply the format; If I call it like frmMyform.mdiparent = frmMdi, then frmMyform.show, the grid WILL NOT apply the format.
