Populating A Datagrid View With Tables?

May 7, 2010

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.

Populating A DataGridView On-the-fly?

Nov 16, 2009

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.

Dynamic DataGrid - Dynamically "transform" DataGrid To Display The Selected Search Template

May 23, 2011

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.

DataGridView1 Not Populating On Load?

Feb 28, 2011

I am using VB 2008

I created a simple form which has two tableadapters to a Access database. On the form I have a combobox that uses the Category TableAdapter and it populates on load fine. the other control is a DataGridView1 which is popluated by the Message Table Adapter based on which Category is selected. It does NOT populate on LOAD and thats my problem.

So the result I'm looking for is when you run the app and my first form loads it

A. Chooses the frist Category in the list (and it does that fine)

B. Populates the DataGridView1 based on the first Category (this is my problem)
The DataGridView1 does Populate after I re-select the Category in the combobox1.

Here is my code below.

Manually Populating A Datagridview?

Jun 10, 2009

Historically I used Tek-Tips for stuff like this but I can no longer access my account there and they do not respond to form based mail. Maybe they got tired of the questions too :-)

I am not a student. I manage a 'large' network. Every now and then I need to roll up something for a specific task. Most of the stuff I write only sees my desktop so neatness and originality are not an issue.My current 'project' is throttling back a few of my users disk storage. I am not allowed to implement Quota's (Server 2003 infrastructure) so I thought the next best thing would be a duplicate file report. I purchased Folder Sized 4 which is a beautiful product (I have used it since it's humble beginnings as Bullet Proof Folders). The end users claim that the filename and date checks are not enough to prove a duplicate. Enter my idea.

I have cobbled together a MD5 hash generator from a function found out on the web. Now I want to send the results to a datagridview instead of my current disk files.I has thought that I could access the rows & columns like dgv.row(x).column(x) = "strFile", dgv.row(x).column(y) = "strMD5"Nope, hunting through the available properties did not point me to any likely candidates.

Again, if this is not the place for questions of this nature please let me know. I am not a programmer, nor am I in training to be one. I just toss little things like this together when needed. Importing a CSV file into Excell is working, but it seems rather lame to be taking so many steps.
