VS 2010 - Update Data Source When Database Field Definition Change

Nov 11, 2010

I'm using a MS Access 2007 database. I modified the field definition of one of the fields in a table, it a text field and I change the maximum length from 40 to 150. I have a data source in my app that contains this table and many others. I refreshed the data source but the change didn't take affect. I went through configure option but the change still didn't take affect. It gives me this error,
The value violates the MaxLength limit of this column.
If I add/delete a database field the data source is updated when I go through the configure process. I finally just deleted the table from my data source and then added it back.

VS 2010 - How To Detect Field Level Data Change

Sep 26, 2011

I have a question about event handling. Is it possible to detect field level data change in vb.net? i don't want my codes to be dependent on the the bound control's event to detect the change on the field value. I'm thinking there must be a better way (coming from a Delphi background). For example: a change on the Qty field will automatically trigger the event to compute the invoice detail Amount - (pseudo-case sample: Amount = Qty * UnitPrice).
In Delphi, every field is treated as an object with its own properties and events. So it's very easy to associate an event with it.

Example:
procedure TfrmInvoice.qryInvDetQtyChange(Sender: TField);
begin
inherited;
qryInvDetAmount.value := qryInvDetQty.AsInteger * qryInvDetUnitPrice.AsCurrency;
end;
How can I achieve the same using vb.net?

Make Gridview Checkbox Field Update Boolean Field In Database?

Feb 7, 2011

There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)

I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.

I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...

is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

Asp.net - A Field Or Property With The Name Was Not Found On The Selected Data Source

Apr 15, 2011

I have an Entity Data Model with two entities in it "Roles" and "Users". There is a navigation property from I have a EntityDataSource and a GridView. The EntityDataSource points to the Users entity and has an Include="Roles" parameter.I've added a BoundField in the GridView that points to RoleName, a property of the entity Roles. However, when I execute the code I get the above error.I have used very similar code successfully in another application. Any ideas why this isn't working?

Here is my EntityDataSource:

<asp:EntityDataSource ID="EntityDataSource1" runat="server"
ConnectionString="name=pbu_checklistEntities"
DefaultContainerName="pbu_checklistEntities" EnableDelete="True"
EnableFlattening="False" EnableUpdate="True" EntitySetName="Users" Include="Role">
</asp:EntityDataSource>

And here is the BoundField:

<asp:BoundField DataField="RoleName" HeaderText="Role" SortExpression="RoleName" />

Update Source Database - Access?

Nov 23, 2009

I am developing a VB.Net windows application to replace a legacy Access database. I started with the legacy database (.mdb) and made changed to tables (like deleting unused columns) and changing anniversaries from 3 columns (day, month, and year) to DataTime etc recognized the need to import data from the legacy system at the time when the new one goes live and wrote an import dialog to do this. And this is where my problem is. The importer correctly imports the data and writes new tables, but each time I restart the application I have the old data back.

This is the approach I took:
In the load event I fill each tableadapter in the new (target) dataset as follows:
Me.ClientInfoTableAdapter1.Fill(Me.DataSet1.ClientInfo)

Update Row In Database But Skip One Field?

May 13, 2009

I have written this set of code that will update an Access Database row: (Total_RAM, Model, etc are just string variables)

Dim Record As InventoryDataSet.InventoryRow
Record = frmMain.InventoryDataSet.Inventory(0)
Record.BeginEdit()
Record.Total_RAM = Total_RAM
Record.Model = Model

[code]....

My problem is the fact that one specific record called "Record.Asset_Tag" exists in the database, but I don't want to programically alter it. That will need to be typed in manually. However, even if I don't put in the line "Record.Asset_Tag = ...", it will overwrite anything in the field with a blank.How do I keep whatever is in the database unaltered in the Asset_Tag column?

Change Data Source For Forms?

Jan 27, 2009

I have a two forms with about 25 bound controls on each in the same solution. All of the data for both forms is in the same SQL table. I need to filter the data and only get the data appropriate to the called form. I consulted an University VB professor and he would only say "it won't be easy".

I tried removing all of the bindings and rebinding them to the new datasource but there were still some remnants (probably from the navigator) that proved illusive.

Is the only solution to recreate the VB forms and bind them to the new datasource?

(using Visual Studio 2008 Professional)
