View 4 RepliesBind Combobox To A New Query?
Dec 2, 2009I have a combobox on a form. It works but I want to filter it with a constant value. I don't want to change the query in the dataset because that would affect other programs. So I click on the little arrow on the combobox in the form design view and then click on Add Query and make my new query which I preview and it's okay. The problem is I can't find any way to make the combobox reference the new query. In the properties for the combobox the Data Source is just the binding source. How do I specify a specific query?

Bind To A ComboBox In A DataTemplate?
May 14, 2010I have a listbox that is bound to an observable collection of Audio (custom class).The Audio class has two properties, DisplayText (string) and a property called TarpIds (Observable Collection of Integer).I need to allow the user to change the TarpID in the combo box for each list item displayed and catch the selection change.I created a DataTemplate that styles the DisplayText property from the Audio object and adds a ComboBox to display the available TarpIDs for this audio (These are dynamic and unique to each Audio).The DisplayText works great, but I can not get the TarpIDs to display in the ComboBox.FYI I set the ItemSource at run time that binds the ListUploadAudio to the Observable Collection of Audio.[code]

Bind Combobox Similar To Datagridview?
Mar 26, 2010I have combobox in a form. The combobox is bound to a table and displays the list of values as expected. What I want to do is also bind the combox to another field in a different table similar to the way the datagridview with combobox works. That is the dgv is bound to the combobox column but the dgv's bound value sets/reflects the value selected by the combobox. I can't figure out if this is possible with a standalone combobox.

[2008] Bind To Just TEXT For A COMBOBOX?
Jan 27, 2009I've got a combobox - style DropDownList.

This appears to be working fine - but I'm a bit confused about the purpose of SELECTEDVALUE in all this. I'm not binding to that.
Bind Generic List Data To Combobox?
Jan 21, 2011Please forgive, I'm new to Silverlight and am still trying to wrap my head around data binding...
I have a generic list obtained from a class using LINQ. The list has 4 objects, each object consisting of a Letter property (string - A, B, C and D) and a corresponding Number property (integer - 1, 2, 3, and 4).
In Silverlight, I have a combobox control and a text block. I'm trying to figure out how to:

Winforms - Bind A ComboBox To Related Tables?
May 14, 2012I am developing a Windows Form Application against a SQL Server relational database. An example of the database schema is:
TableA
------------------
PK A_ID uniqueidentifier
A_NAME varchar(254)
[code]....
In the form I have a ComboBox (cboA_ID) to select the TableA record (DataSource = TableA, DisplayMember = A_NAME, ValueMember = A_ID) and a TabControl where controls on each tab are bound to fields in either TableB or TableC.My question is, is it possible to bind cboA_ID to TableB.A_ID and TableC.A_ID?This is my first database application so if there is a better way to do this I'm all ears. I have set everything up using the wizards in Visual Studio 2010, so I'm still not 100% familiar with what all the various TableAdapters and DataSets do.

[2008] Bind The Combobox To It's Record But Also Display All The Possibilities?
Jan 17, 2009this code
Me.vendorLookup.DataSource = vendorBAL_C.vendorTable
Me.vendorLookup.DisplayMember = "SimpleId"

Makes the combobox have a list of Names (simpleid) and PK (vendorid)
How do you make the combobox also be bound to a specific row of a record in an "case management" table? I've already used the datasource for a table of vendors - right?Or is this where I put two tables into a DATASET and make that be the DATASOURCE?
Bind Combobox To Datatable And Object Property Causing Duplicate Bindings
Aug 19, 2011I'm trying to populate the list of a combobox by binding it to a datatable. Also, I want the selected value of the combobox to be bound to an object property so that when the selected value changes, it's automatically updating the object. However it's causing an error at runtime: "This causes two bindings in the collection to bind to the same property.
Parameter name: binding" I thought binding the dropdown list to a datatable and the selected value to an object were different properties but obviously I'm not getting it right.

View 1 RepliesBind Database To Objects?
Mar 2, 2012I don't know if this is even the correct terminology but I was wondering if it is possible to bind a row (of data) from a database to an object. I am working on a school project and we have decided to create this application to track a user's BMI/BMR and compare it to the amount of calories they have input. The program doesn't go too in depth so it does not store the calories consumed in the database.
So here is my problem. I have a row in my database:
First_Name -- Last_Name -- Height_Inches -- Weight_Pounds
And I guess what I am thinking I want my program to do is if I have an object with properties for FirstName, LastName, HeightInches, WeightPounds, is to somehow query the database for one row and put the values into the object. All we have learned so far is binding the data with controls which doesn't really help in my case since the work is going to be done behind the scenes.
Bind Combo Box To Access Database?
Dec 26, 2010I'm trying to bind a combo box to a Access database field. I'm trying to do this with code instead of using the data sources wizard as I was told that this would be more flexible and better if distributing the finished program to other computers.
The result is that the form runs, but nothing is in the combo box.
I have also not used a dataset in my code, only a data table. Am I correct in thinking that this is plausible?

Bind TWO Different Database Tables To ONE Textbox In VB?
Mar 20, 2011I was wondering if there is any way to bind TWO different database tables to ONE textbox in VB? I've spent the whole day going through tutorials and different webpages and I've found nothing at all on this...
Well let me try to explain what I want to do exactly: basically I have multiple buttons on 'Form 1' and a textbox on 'Form 2' asking the user to insert a value which will then go to an Access database. But here is where it gets tricky for me: IF the user presses Button 1, the Value inserted on Form 2 will go to a field in the database whereas if the user presses Button 2 to open Form 2, then the value will go to somewhere else and so on.
This would be easy to do if I was to create multiple forms or multiple textboxes, 1 for each button but what I really need is 1 form/1 textbox that would work for all of them... [URL]
