Data Bind A Drop Down List In A Gridview From A Database Table Using VB?
Dec 4, 2009So in this gridview, there is a column for status and I want to have a drop down list with Pass, Pending, Fail appear when the edit button is clicked. These values are already in a table, so I need to somehow bind from this table to each ddl for every row.Here is the column from the gridview. As you can see, I would like to just have a label showing when not in edit mode, and a ddl when the edit button is pressed
<asp:TemplateField HeaderText="During Production Status" SortExpression="DuringProductionStatus">
<EditItemTemplate>

Getting System.Data.DataRowView In Drop Down List As Opposed To Values From Database
Sep 30, 2010I'm populating a custom dropdown list control on the fly that's tied to data grid using VB .NET 2008. The form will display all the manufactures when the edit button on the data grid is selected.
The dropdown I created works fine. However, when I try to populate the drop down with the respected manufacture values from the database, I only get a value of "System.Data.DataRowView" that being populated in the dropdown list as opposed to my values from the database.
Here's the basic code I use to first create and populate the drop down control:
<asp:DropDownList ID="Manufacturedd" Runat="server" DataSource='<%# m_ItrackerData.Tables("Misc_Manufacture") %>' SelectedIndex='<%# getSelectedManufacture(DataBinder.Eval(Container, "DataItem.Manufacture"))
%>'></asp:DropDownList>

Drop Down Lists Connecting To An Access Database?
Dec 1, 2010I have a couple drop down lists connecting to an Access database. I can get the first drop down list to populate with the departments I have listed under "dept" in my access file. After someone selected a "dept" i want the second drop down list to populate with the names ("name"). Right now the second dropdown list is showing up but isn't poplulating. What am I doing wrong?!? I would like to include a third dropdown list for another selection with a button to then show things from the specific selections. Right now, I just need to figure out how to populate a list upon another lists' selections.

View 22 RepliesPopulate A Drop Down List With State Information From A Database?
Jun 7, 2011Background - I'm trying to populate a drop down list with state information from a database. I'd like the full state name to be the option and the state abbreviation to be the value. Example:
<option value="AL">ALABAMA</option>
Current Progress - The full state names and abbreviations already exist in the DB. I've successfully populated the DDL with full state names from the DB. Here's the code I've used to do this (minus stuff I've deemed irrelevant).Model Context (generated from template):
Partial Public Class BrokerCRMEntities
Public Property States() As DbSet(Of State)
End Class
State Model (generated from template):
Partial Public Class State
[Code]...
Question - In addition to populating full state names like I've done above, I'd also like to populate the value of the select options in the same DDL with the state abbreviations in my DB/model. How is this done?
Update Database With Drag&drop-produced DataGridView?
Apr 29, 2010I am putting together two programs... basically one to enter data into a sql server 2000 database, and one to view the entered data and modify some fields. The data-entry part works well, but the second part is giving me some problems.ince the second part should really be a simple program, I created a DataGridView of my sql server table via drag&drop (just pulled the table from the data sources). Now I need to save back any changes to the DB. The part giving me problems is the OleDBCommandBuilder:

Trim String Of Drop Down Menu Text Coming From Database?

and my second question, I have a string being sent into a drop down menu that gets the data pulled from an access database using a data source control. How do I format it so say, it only shows the first 100 characters of that string in the dropdown?
Checking For Text Data When Doing Drag And Drop?
Nov 1, 2009I'm doing drag and drop from a list view. In my starting list view's ItemDrag event handler, I say (amomgst other things):
data.SetFileDropList(coll)
data.SetText(CurrentFolder, TextDataFormat.Text)
sender.DoDragDrop(data, DragDropEffects.Copy Or DragDropEffects.Move)
CurrentFolder being a string that holds the name of the folder represented by the list view. In the target control's DragDrop event handler, CType(e.Data, DataObject).GetText evaluates to what CurrentFolder was when ItemDrag was executed.But: e.Data.GetDataPresent(TextDataFormat.Text) always evaluates to FALSE.If I replace "TextDataFormat.Text" by "DataFormats.Text" (in both places) the result is the same. I am asking this although my code does what I want, because I feel that I should not call CType(e.Data, DataObject).GetText before I have established that TextData is actually present. So how do I properly check for the presence of the text data.
Filter Data Based On The Drop Down Filters?
Jul 27, 2011I am looking to find the best way to do the following: Filter data based on the drop down filters, as long as I am within the same product category (e.g. toys, puzzles, etc...), but in different web forms (product grid and product detail).So if I select toys under $25, I need the filter to the toys in a grid format, but if I click to view the detail I need the filter information so I can filter the related items display.Display certain filters depending on the product category.Right now I believe that if I build a user control and session variables that I should be able to accomplish this.
EDIT: Right now I am using the page_load event to update the data and would like to avoid AJAX for right now.

Allows The User To Drag And Drop A Xls File Onto The Form And A DataGridView Fills With The Xls Sheet Data?
Mar 25, 2010I have a VB .NET (VS 2008) application which allows the user to drag and drop a xls file onto the form and a DataGridView fills with the xls sheet data. The user than can apply changes to the data or add entries. Data integrity is checked during the load into the DataGridView (duplicates are removed and invalid entries are filtered out). After doing all this the user can click a button and the data is uploaded to a SQL server (2008) DB. I have a primary key set up (row number) and I have a compound key in the SQL table.
It is all working beautifully. Now here is my question:
I want to check for duplicate entries (between SQL server and DataGridView data) before the data is uploaded and commited to the table. What would be the most efficient way to that?

When I call up different records on the same panel the drop downs immediately "set to the position" of that rows language in the list. But when I call up another panel - tied to another database table - I see that language in the drop down.

View 6 RepliesSQL Data Access: VB2008 / VB2010 - WinForms - Create A Datasourse And Drag / Drop Fields Or Tables On A Form To Create A Grid
Oct 22, 2010I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.

Jun 22, 2010I am sitting with a situation that I have to combined (3 years) for 26 site of 29000 database files where there is 1 table in each data base called RECDATA, I need to combined all that data Into one database file called RECDATA.
For example there is a database called DB1 with a REDATA table inside it, and then DB2 with a RECDATA table inside it, DB3 with a RECDATA table inside it est. So I need to put all the Recdata into 1 Database file, or to copy all the RECDATA from all the database files to 1 RECDATA they all have the same columns All I need is to get all that data into 1 RECDATA table.
The program where this database comes from is a voicerecording system creating a new database every day. There is 1 database just for indexing (to view the recordings) and then the daily database is where the recording lies in, that Colum is called RECFILE. I will give you a example of the 2 database.
IDE :: Failed To Retrieve Data From The Database, Database Vendor Code 9421?
Jan 17, 2011I have a report made in Crystal Reports XI. The report is generated and exported to PDF in visual basic script using COM interface. Generally everything is running smoothly, but in one case generation breaks with error: Failed to retrieve data from the database. Details: [Database Vendor Code 9421]
Database used is MSSQL 2005 connected over ODBC to CR XI. When I am opening report with exactly the same parameters in Designer, everything works fine.It looks like it is data related, but it is hard to trace since the whole report is pretty sophisticated. Anyway I spent half a day on crawling over Dr. Google and it seems that he has no clue what might be an issue.
