I have got a database with a bunch of tables in it. So far, i can query that database and get the names of all the tables into a listbox. this is sweet.
What i need to do now is to enable the user to click on a table name thats listed in the listbox (which were put there using the
GetOleDbSchemaTable method)
and when they do, i need to populate the Datagridview with the relevant data thats sitting in the table that is listed in the listbox.
I've tried a couple things to get the tables themselves to populate the DGV(which kind of works now), but not the Data thats sitting in the individual table.

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.
I have a form which the datagridview will be built manually by reading in certain data from a text file (this is because the data in the text file will change periodically)The code is correctly adding the proper amount of rows but it is NOT putting the required values in the cells. Any thoughts?

I am working on a weboage that will display questions and answers (maybe 5 at one time, maybe 7 at another time) returned from a database table. The questions will each be displayed in a div and the related answers displayed in another div. The question will have an icon "Show Answer / Hide Answer"
How can I go about creating a div and then populating it with values from a table?
The general problem is that I can't get the foreign key in one of my child tables to populate the primary key from the parent table. I have a parent table named "ISSUES" and a child table named "ISSDESC". The primary key for ISSUES is ISS_ID which is an autonumber. The foreign key is ISS_ID in the ISSDESC table which is just a number. I'm using MS Access and an OLEDBConnection as the method. I've created the relationship in MS Access and also created the datarelation in the VB.NET code.

I have a DataGridView which reads data from a custom (CSLA) list object. The dataset might have 100,000 records, and obviously I don't want to show them all at once because, for one, it would take ages to load.I think it would be nice if I could read the first (for instance) 20 records, and make it so upon scrolling to the end of the list, it reads the next 20 and adds them to the DataGridView.
I have experimented with various ways of doing this, mostly using a custom class inheriting from DataGridView to capture scroll events and raising an event which adds new records. I will include the code below:
Public Class TestDGV
Inherits DataGridView
Public Sub New()
[code]....
Though this (sort of) works, it can be buggy. The biggest problem was that if you used the mouse to scroll the DataGrid, it would get stuck in a loop as it process the scrollbar's ValueChanged event after the data was added. That's why I added ScrollbarOff and ScrollbarOn - I call them before and after getting new records, which disables the scrollbar temporarily.
The problem with that is that after the scrollbar is re-enabled, it doesn't keep track of the current mouse state, so if you hold down the 'Down' button with the mouse (or click on part of the scrollbar) it stops scrolling after it has added the new records, and you have to click it again.
i have a datagridviewcomboboxcolumn that i am trying to populate. i set up the DataSource property using the wizard, there after i selected the DisplayMember from a corresponding drop down of fields from the table set up in the DataSource and then lastly i selected a field to be the ValueMember. problem is when i run my program datagridviewcomboboxcolumn is not populated.there is no drop down at all. what should i do to see my drop down or perhaps i need to set up in code.

red purple pink black neon

I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
what are the differences between the WPF Datagrid included in the .NET Framework 4.0 versus the Datagrid included in the out-of-band WPF Toolkit? I understand that the toolkit version was released first, and targets the .NET Framework 3.5 SP1.
I needed a WPF datagrid quick and have utilized the toolkit version in my applications. I'm considering moving the application to .NET 4.0 and am wondering what the pros/cons will be in changing out my existing datagrids for the new ones.
