Datagridview Is Moving From A Tabcontrol Onto The Main Form
Sep 18, 2010
Problem: My datagridview is moving from a tabcontrol onto the main form when I execute the below code. I desire it to stay in the original position. Details:
1) I created a MAIN datagridview1 for my master on tab 2 (OK) - this is for editing, deleting etc.
2) I created datagridview3 on tab 1 for implementing 2 textbox filters (OK)
3) The actual filter code fires on changing of values in two text boxes
The above works perfect except when the code below is executed, datagridview3 moves from tab1 of my tabcontrol to my main form. How do I keep it from moving (desired) or at the least move it back to control tab 1?

I'd like to keep all my SQL data related code in a separate class and only have UI related code in my main form. However, the TableAdapters are automatically placed on the main form and, of course, the auto-generated code placed in the Form_Load event.
Obviously, it's easier to keep it like that but is it possible to move them to a different class?

I have a project with a form in which I have a tabcontrol with several tab pages. In each tabpage I have a datagridview and some textboxes and some comboboxes. I managed to refresh one datagridview but it stopped working. - I don't know why. Here's what I did:
Public Sub RefreshGRD()
Me.Adapter.Fill(Me.DataSet,"table")
End SUb
And I called this fnction before closing the connection for each button that adds or deletes or updates. Before calling it I cleared the dataset.

I have a form where the user will choose multiple clients from a subform that has a DGV.Each row has a checkbox indicating that it has been selected.When the user is finished selecting the clients, I need to store the selected clients ID Number, Name, and Program Number either in a temp table or another method to only handle about 30 records.After that part is done, I need to create a new tab for each client which has a UserControl on the tab. I have the new tab thing working but I need to learn to apply the client to the first new tab/user control then create another and so on.
Private Sub frmCaseNts_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I have a tool window that I want to stay above the main application form, but not stay on top of all windows forms. Similar to the floating properties window for visual studio - it always stays on top of the main VS window, but if I select another program, like internet explorer, the floating properties window will be behind internet explorer.
What I have is an application that has several forms that may be displayed at the same time. I have a Messages form that displays messages generated by the code in the form, that gives the status of the application. Obviously, the user would not normally be working on this form, but they may want it to be visible to see the status messages from the program (File saved confirmations, etc). So, my two options right now are I can set the form to be on top of all other windows forms or, when the user clicks on the main application form, the messages form would be hidden by the main form.

I have a form created which an unbound datagridview that has three columns. "Position", "ID", "Name". The data is being added at runtime into a database upon the forms completion. (I don't want to add unnecessary rows to the database in the event a person clicks Cancel.) What I need to do is on the deletion of a row in the datagridview, search through the rows "Position" for a "HJ" value. If it's not found, change the "Position" value of the first row to be "HJ".

I have a button 'Next' which performs navigation, but at the end I want to move to the next row in a datagridview to show the user what record they have moved to. I expected this to be easy, using the following
Dim x As Integer
x = dg.CurrentRow.Index
dg.CurrentCell = dg.Rows(x + 1).Cells(0)
At end of last record it show Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index + visual basic 2008

I have a datagrid control on my form that receives data from a device on the COM port. I strip out the data I need and put it into the currently selected cell. When I load the grid, I find the first empty cell and set the focus so each load presents the user with an empty cell to start receiving data. Once I get the measurement, I need to move to the next cell down (like hitting enter in the grid). This will allow the user to do measurements with the external device without having to move to the next cell.

I have a main form with datagridview containing a list of contacts:
VB
Public Class Form1
Private Db As New DataClasses1DataContext
Private Sub Form1_Load
[Code]....
After saving, I get the correct message ("Saved"), and the DataGridView in the first form gets updated in real time.
But... when I take look at the data (or close and reopen the forms) the data in the database (SQL server) have not changed! What happens!

How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow()
Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize it?is there any way to make it Movable while it loads?

[Code] I want like to check if a file exist on main form, if not: force open settings form. And then when the user is closing the form with exit button = check if the file exist again. If it doesn't exist, close application. It's a huge application and I need optimized on most parts. Also, the settings form is asking the closing question two times.

How can I update and get values in a Windows Forms application while moving one form to other form (like cookies)?
I need to update the values to some variable and again I am going to refer stored values and need to do some calculations.
I have used cookies in ASP.NET but I am not able to find out the same concept in .NET Windows Forms (C#).
How can these issues be resolves?

I'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.
I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.
My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.
In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.
I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.
Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox form ):

I have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.

I want to create an IMAGELIST in a main form and add to it then have it accessible within a child form. I found several MS examples on database shared access but this is NOT the concept I am after. Straight forward:
Child_Form.<function_to_execute_in_child_form>(The_Passed_Imagelist)
So, within the child form it want to do whatever I like to the IMAGELIST! I have tried passing the object by reference and anything I could think of.

When I open my child form,
frm_Analogs.ShowDialog()
It opens up the new form, but now I can not interact with my main form. It will not accept focus or allow me to interact with it.
Do I need to change the form type?
