VS 2010 Refreshing A Datagrid When Add - Deleted Or Edit A Row Via Another Form
Apr 5, 2011
so I am a little confused. I am trying to refresh my datagrid when I have either add, deleted or edit a row via another form. I have it so my main form shows the datagridview, I have bound my controls to the database and I see all rows, no problem. I also have it setup to double click a row and it brings it up in another form to edit that record. This works. but it doesn't refresh the datagrid when saved. I am trying to follow this thread, specifically this post Refresh Datagridview - Post 2 Here is how I am loading the datagridview in main form

The gist of the program is to:
- Read a CSV file into an array
- Get this visible in a list box, so the values can be:
- Sorted
- Edited
- Deleted
- Added
- Finally save these manipulated values back to the text file

Basically I have two forms - Form1 has a DataGrid on it (Infragistics) and in the double-click row event it creates an instance of the EditForm and passes along the UniqueId for editing. Once the user saves the changes (if they make changes) - I want the DataGrid on Form1 to refresh. Here is how I thought I could get this to work ... I create a public property called RefreshRequired as boolean. Before unloading the EditForm it sets this property to true. Then Unloads. This continues the code in Form1 (which showed the EditForm as modal) but RefreshRequired is still showing as False? Why isn't my EditForm able to set the property?
FORM 1
Private Sub grdList_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdList.DoubleClick

I had issues in refreshing a form that is bound to different tables in a database. Various forms allow the user to change and add and update information on the form via the database. I had created a public sub in that form that the other forms could call, after saving the data, that was supposed to refresh the data on the main form. This was not working so I researched the problem. I came across this page which pertains to Form.Activated: [url]
I placed all of the table adapter fills into this event, instead of in Form_Load, and it seems to work now, when the form first loads, and when other forms update data. My question is does anyone have experience using this and what are the consequences, if any, in using this to reload/refresh the data showing on the form?

I have an application that saves details to then be viewed in a datagridview on another form. Clicking on an entry in the datagrid (I want to make this double-click, but haven't bothered to try yet) highlights the row, and loads the values to a new form, in read-only text boxes. Clicking Edit changes the read-only value of these text boxes and allows you to edit (obviously) the contents. I have another button, Save which I want to click to commit the changes to the loaded items in the datagrid.

I have sub routine that is called via events like so.
Private Sub dgvQA_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvQA.RowEnter
The problem is, is that it only fires correctly once.The e event variable keeps the same row even though I have now clicked on a new row.Meaning the next time an event occurs it has the same values as the previous event, when they should be different.How do I make it return the correct rows value when called the next time?The sub, depending on what row is select, creates a new form like the following
Dim NewForm As QA
NewForm = New QA
NewForm.UseParm = 1
NewForm.ShowDialog(Me)
Which is then worked with and closed, there after the sub continues normally.The sub also calls a different sub which may alter text fields within the datagrid view refreshing the data to reflect the work within the form that was created and used.

So I have my main form (Form1) and I have a module called globalMod. On start up, Form1 loads, and globalMod contains functions and global variables (using Friend). I need to be able to have a function inside of globalMod edit a label/text box/etc in Form1. I tired Form1.object.Text = "content" and it doesn't do anything, even if I update / refresh the form.

I am working on supplier maintenance file. From mainmenu, opening first form shows records on datagridview through databinding. Clicking add new record, i fired a second form as my data entry with detail view through databinding, minus navigational buttons. I left the delete and save button only. Once through data entry, i save it on server. My problem is, how can i reflect the added record on the first form while i am on my second form? I prefer the new record be added only to the first form. I don't want the idea of retrieving the records again from my server.

I am trying to refresh a datagridview from a second form to display newly written data. I have read the posts on this topic and can't figure mine out. My first form opens and you input data into text fields, etc. and then you need to select items from one table to copy and write to a new table. The datgridview on the first form shows the new table, and I have a new form that pops up to select the line items to add. Everything works perfectly except when I close the selection form after selecting lines, I would like the datgridview on the first form to refresh to show that the lines have been selected and displayed in the datagrid.
My data is loaded into the datagridview as so;
Public
Sub ShowVoucherLines()

I've been working on this game the past few days, a simple game where two people control different tanks, and shoot each other, very basic so far.The problem I have is when one player is dead. I have the form recognizing each players death by using this code (It's within a timer subroutine)
'Player One Dead
If intPlayerOneHealth <= 0 Then
btnReplay.Visible = True
End If
[code]....
and that code is replicated for every key pressed (Arrow keys, WASD, e, and end). Those booleans are handled in a timer subroutine, where if the boolean is true, they will move/shoot. (Turning the booleans to false is done in the 'Private Sub KeysUp' subroutine)
TL;DR How do I get the game to restart itself when a player dies and hits the replay button?
P.S. I've tried 'Me.Refresh()' as well, and that didn't do anything

It uses a Drawmap() sub with map data to create the map on the game load, but I can't seem to get it to refresh, and then re-draw the map based on player location. For example, if the player walks into a door, then it refreshes the map to show them in a building. Any advice on this? Code below:
Imports System.Drawing
Imports System.Windows.Forms
Public Class Form1

I am in need of a method to refresh a webbrowser object's IP address. Until now, I've just change the value in the Registry. However, the webbrowser only gets the IP when it is first instantiated (when it first navigates to a web page). So, it will not update every time I change the registry. I know there is a way to simply change the IP of the webbrowser itself, so that it will update the IP every time the command is run in VB6, however I have no idea how to do this in VB.NET.

i have a form with 6 tabs on 3 of which have controls, spent a lot of time putting it all together, set it up to link to a SQL DB, all working fine,Until....at the bottom of the form (in design mode) you have the icons that say BindingSource1 and CustomerDataSet1 etc.Well i accidently deleted some, now when i run the form i got an error saying that it couldnt load, i see the code is there but the form is just the blank form you get when you start(the form is still the same name and if i click view code all the code is there, but on the form are no controls, no tabs ... its all gone....(i only deleted a binding source ) i dont understand where its all gone.
when you click on the undo it didnt put the deleted items back (and i am not sure which one there were) now that the form has gone back to normal there are no Binding sources at the bottom I opened the designer code, i see the names of all the missing items, e.g. CustomersDataSet1 and TblCustomers1BindingSource1 e.t.c do i just re add those back to the bottom of the form and then the main controls will re appear?
I have looked through the code and re added the binding sources and adapters that are referenced in the code along with the Binding navigator, if i run it the form is still blank.I have tried to add the controls back and when i do it adds it as e.gTblCustomers1BindingSource2 if i try to rename them to the name they should be ie. TblCustomers1BindingSource1 it says it already existsI am using VB 2008 Pro?
