C# - DataGridView WinForms Auto Reload/Update/Refresh?
Feb 16, 2012I have a windows form with a DataGridView control.I bound it into an attached DB file (.mdf).I perform insertion by generating a dynamic Insert statement. I then pump this sql statement into a SqlCommand object and perform ExecuteNonQuery() method. All of these is performed by handling a Button click event. The button and the gridview is located on the same form.
Public Sub InsertRow(ByVal param1 As String, ByVal param2 As String, ByVal param3 As String)
Dim strConn As String = (the connection string)
Dim sqlConn As New SqlConnection(strConn)
[code]....
After the code execution, the DataGridView is not updating (remains intact). I have to exit the form and reload it to have the updated gridview.For certain reasons, I can't use DataTable object.But I would like to have this gridview updated everytime I run the insertion.
DataGridView Does Not Refresh After Dataset Update?
Apr 13, 2012I have a vb.net form with a dataGridView
The dataGridView data source is the dgvTableAdapter with this sql statement
SELECT membres.ID, membres.refere_par, bands.titre,
membres_1.prenom & ' ' & membres_1.nom AS reference_nom
FROM ((bands INNER JOIN membres ON bands.ID = membres.[band])
INNER JOIN membres membres_1 ON membres.refere_par = membres_1.ID)
[Code]....
I know the delete statement works because I saw the changes in the database. If I close the form and reopen it, the dataGridView is up to date.
The membres table is an access table
I'm running the app in visual 2010 debug mode.
DataGridView - VS 20008 - Automatically Update Database, Refresh Grid On Initial Window

Once I hit a save bottom on the second form how can I automatically update the database, refresh the grid on the initial window but remain on the same row on form1 that I double clicked on in the first place. Currently I am re-loading the datagrid on the initial form with all the data once I close the second window down.

View 6 RepliesForm Don't Auto Refresh When Change Certain Values
Dec 23, 2010i am currently making a project which is to make a cinema screen booking system. My main problem is that although i have most of what is working i need to find a formula to give the full result (overall price) in a label. My other problem is the fact that when i interact with my form certain things dont auto refresh when i change certain values e.g i change number of seats but it doesn't auto refresh the price or anything OR i click one discount then another but nothing changes and it keeps the old value.
Okay in my menu i have a CombBox (ComboBoxScreen) for choosing the film and there are 3 films to choose from in the drop menu each with their own price. I also have a Textbox (NumberSeats) for inputting a number of seats you want to book for chosen film. And lastly there are 3 radio buttons each with different discounts. e.g No discount, 10% off and 25% off. A formula to work out the overall price uses all three functions/tools above. [Code]

View 3 RepliesStop Webbrowser Objects From Stealing Focus If Auto-refresh Header Is In Use?
Jul 12, 2010I have a VB.net form which has two webpages embedded. The webpages have a 5 second auto refresh built into the HTML header as the information is constantly changing.
The problem I have is when I pull up a secondary form, I lose focus to the 'Main' form everytime the webpage refreshes.
Is there any way to stop the webpages autorefreshing in the form and I will build in a refresh command into a timer I already have in place and then I can start and stop the refresh at will.
Unfortunatly I cannot amend the source code of the HTML as this is required for a different process elsewhere.
VS 2005 "refresh" The Sql Update Commands After Every Tableadapter.update?
Jun 15, 2012Environment = VB.NET 2005 & Pervasive SQL 9.5 ADO.NET In a simplified example, I have single database table (customers) with the columns "customer_code_PK" and "customer_name" This table is presented in VB.NET 2005 as a single form datagrid (bindingsource/dataset). In this example, the database table is populated with the following data
customer_code_PK customer_name
SHELLShell Oil
BPBritish Petrolium
MOBMobile
In very simplified terms, code does the following;
sub on form load
fill dataset with database records (select * from customers)
[code]....
The datagridview loads the records correctly.Here is the sequence of operations that produces the bizzar behaviour.In the editable datagrid;
1.remove the row with PK = MOB -> save_button -> Database correctly updates
2.add a new row with PK = KFC -> save_button -> Database correctly updates
3.remove row with PK = SHELL -> save_button -> Database exception occurs
On this last command, the row SHELL is INSERTED!!, not removed.However, If I change ths save_button routine to this
save_button
call generate_custom_updateinsertdeletecommands
bindingsource endedit
[code]....
It works correctly !Is it correct that you would need to "refresh" the sql update commands after every tableadapter.update?
Refresh Datagrid After An Update?
Jul 30, 2009I have a main form with player information (it's a sports application). To add or edit a player the user presses a button which opens another form. They either add or edit from this point. When they click 'OK', it saves the data to the database table then goes back to the main form. The amended or new info doesn't appear. If they close the application, then reopen, the new info appears in the datagrid now.
how I can get the datagrid to refresh once I press 'OK' on the input form?

View 1 RepliesGDI+: Update Or Refresh Only Certain Parts Of The Screen ?
Jan 30, 2010I'm making a game using vb.net and GDI+. I've been encountering frame rate problems and one solution that was suggested to me was to only refresh certain parts of the screen. I was also told one way to make this happen was to use rectangle or region structures and since I already have these as hitboxes it seems like a perfect way to efficiently reduce the drop in frame rate.
The only problem is that I have no idea how this would work and so far my google searches have been fruitless. Yet again I turn to this very helpful forum, can anyone help me? By the way I've set doublebuffered to true on my form to get rid of the annoying flicker.
Questions. How do I update or refresh only certain parts of the screen?
I'm using a timer set to tick every millisecond to run everything and it refreshes the screen every 2 milliseconds simply using me.invalidate; each time it ticks things move a little bit and stuff happens that triggers other events etc. The problem is that when the framerate supposedly "drops" things start to change. "Bullets" and projectiles appear to travel many times faster and much less smoothly than they do when there a less objects moving on the screen, it's almost as if the timer runs faster... What's the reason for this? Is there a way I can change this? I remember hearing about a "stopwatch" or something that someone used in their game that was more consistent or something.
Also I'm aware that vb.net with GDI+ isn't exactly the best language to make a video game in but it's for a school project and I have no choice in the matter.

View 2 RepliesRefresh/update Tab Pages To Reflect Changes?
Aug 6, 2009For some reason my tab pages won't update their data when I change the data contained in them.

But if I have one of the tabs as the one in focus when I change my company, it is updated correctly.
