I am creating a database for Employees. In that I have some issues.I am trying to bind my data using data source. In the list box properties I set
lstemp.Datasource = Employeedatabase
lstemp.Displaymember = "EmplyeeName"

View 1 RepliesI need to create a new tree view, that is linked to a particular table.
Each row in the table has a parent id that links back to the table's primary key, and that defines the node hierarchy. So that relationship needs to be indicated in the databinding.
Am I able to use the standard treeview control in Visual Studio 2008, or do I need something extra to make this work?
Resources: Visual Studio 2008 Pro (currently in 90 days trial)
Platform: OS - Vista Home Prem 64-Bit
Language : Visual Basic
I'd like to bind my textbox into two (column)from different table is it possible to do this? I already know how to bind (one-to-one) controls and table.
Here's a part of XAML of the application I'm working on:
<ListView Name="lsvCustomerDetails" ItemsSource="{Binding myDataTable}">
<ListView.View>
<GridView>
[Code].....
Is this code correct to fill this table? If not, why? Honestly, I've found several perspectives on how to do this sort of thing, some of which are linked below:

I have a query that will go away an and find data
Dim HSNs As String = String.Join(",", ListOfHSNs.Cast(Of String)().ToArray())
Dim query As String = "SELECT VALUE O FROM v_BillData AS O WHERE O.HSNumber IN {'" & HSNs & "'}"
Dim hs As New ObjectQuery(Of v_BillData)(query, CType(Session("ObjectCon"), ObjectContext))
What I now wish to do is to use the results of this query to databind to a EntityDataSource?
I have created a form with three comboboxes. means
FirstNameComboBox
MiddleNameComboBox
LastNameComboBox
All fields are select ( name ) from a "CustomerName" table. "CustomerName" table is have more than ten thousand records. I am use three binding sources its worked great but it is very slow bcz three comboboxes are filled data on form loading time. I am using visual studio 2010 (visual basic).
I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

Modifying data with the ListView's EditItemTemplate by programmatically settings its DataSource property and calling its DataBind method. I don't have option to use data source control for ListView. All ListViews are bound with data from code-behind. So, I have to handle the Edit/Update mode of ListView manually. [Code]
View 2 RepliesI'm trying to connect a VB application (2010) to an MS Access DB by adding a data source from the data menu but I receive this error message "The connection you selected uses a local data file that is not in the current project.Would you like to copy the file to your project and modify the connection ?
If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)
If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB
how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.
I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

can data reader be used as a data source for a grid control?
View 5 RepliesI have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.

I have a bit of code that reaches out and grabs a series of rows from SQL Server DB. I perform an inner join to get some related table data. In the process I get returned the user id of the creator of the data. I then want to pass this into a query to get back a full name. I am having no luck figuring out how to do just that.
