How To Refresh Form
Oct 7, 2011
I have a form, with a datagridview. I can see the data and the related records in the DGV.I have another form that this one calls to add a new record. I need that because there are some specific parameters i need to control. But when the focus returns to the original form, I can't see the new record, even though it is there (I see it in the database).If I close the form and enter again I can see it, that is not what i want.How can I refresh the tables after the other process adds data to them?

I have a parent form that has a combobox. Whn the form loads I get the data from the db and bind to the combobox. that works fine and here is the code I use in form load to cause this to happen: [code] Now if there is not an Account Type, I have a button that will pull up a small form to allow the addition of an account type. The popup form adds the data back to the database just fine, but I am now trying to get the combobox to refresh its data. So I call a public Sub that is located in the parent form to from the popup form to accomplish this task and I have walked the code and the sub is called and appears to work correctly, but the new data never appears in the combobox. Here is my public sub that i call to try and refresh the combobox on the parent form. [code] But when I go back to the parent form, the combobox is not updated with the new account. How can i get the combobox to refresh from the database with the new data?

I am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters.
Here is the code that calls the sub form.
Code:
where ds is the dataset to fill the datagridview and rb is the string from a radio button on this form.
Here is the code in the sub form.
Code:
Now, I need to refresh this sub form every -- minutes, depending on how the user wants it to be. For this I have given a NumericUpDown control to select the mins. All this works fine. But how do I refresh the dataset and the datagridview?

I have created a simple VB.NET application with one form and a few modules. When a user clicks on a run button of the form the application starts and goes through differet cycle, while updating the user on status bar, runs for less than four hours.
The application works fine, it gives desired result. However, it is not able to refresh the user form, meaning status bar remains same after some time (it suppose to increment). Even when I take mouse on the form it shows timer symbole instead of default one.
My application commands another device using GPIB. Basically, PC running my application commands the device. If I look the display of device it gives correct information.

I'm using Mysql database and Visual Studio 2005. I've got a form with datagridview, After making the changes in the data, it is saved in the database. The data gets saved in the database, but the modified data does not get displayed in the datagridview. Only if I close the form and open it again, the changes are displayed. I want to provide a button (refresh-button), which on clicking will refresh the datagridview, so that the modified data is displayed without closing the form.

Been playing around with this and simply can't get it to work
I've got a form and I've created a button called refresh. The button is meant to do exactly that. What happens is that when the form loads, it checks the database for values. If it finds values, it creates a dynamic edit box related to the value.
I open the form and it paints accordingly and as I expect it. If I delete a value from the database then click the refresh button, it should re-draw the form and paint the background grey. The logic definitely works because I trapped the bit of code and it does hit the part where it's meant to set the background grey.
Now, I'm not sure I'm refreshing the form properly because all I'm doing within this sub is calling the form on load event: formLRQuadrantSchedule_Load(Me, New System.EventArgs)
This seems to work logic wise, just not doing what I want. So, I tried this (amongst several other things):
Dim dynTextBox As New TextBox()
Me.Controls.Add(dynTextBox)
With dynTextBox
[Code]....

I'm having an application which has to perform exporting and importing data. At the moment he runs those functions, I want a form to popup with an animated gif, so my client sees that the application is still running.But the animated gif stops sometimes, because he is busy doing stuff (like copying files, etc...)Is there a way to tell the form to refresh automatically every 0.1 sec, so the image runs fluidly. I tried to put a timer in my form, and start the timer as from the form is shown...the timer_tick says he has to refresh, but he doesn't want to do that.

I have an app that opens up 3 forms. 2 forms have a datagrid the other form has book lending details. The datagrid forms are for books in the library and books that have been borrowed.
Both datagrid forms will be open as shown in the attachment, how do I refresh the "Borrowed Books" datagrid form from inside the form that has the "Book in Library" datagrid.
So far I've been able to update the "Books in Library" datagrid because control comes back to that form after the details form closes but since the "Borrowed Books" form is still opened up, we would like to refresh the datagrid on that form.

I am trying to update my form once the delete button is clicked. There are several fields like Name, Date, Date of Birth and so on. Once I delete record I want the form to automatically load with new / updated data. This form fetches data from MS Access using OLEDB. Once when I close the application and reopen then form will be updated with new values. But I want this to happen once the form loads after deleting.[code]

got question on using windows forms in visual
what i have going on is on one form i have a calendar that is for the month of may. when you click on may 1...it opens a form with some combo boxes and a gridview that displays the choices from the combo boxes.
my question is this..
can I just link all of the other 30 days in may to go to the same form or do I have to make 30 duplicate forms LOL...i know it is a kinda silly question but I really dont know.
It would be a travesty if the user were to click on may 2...and get a form all filled out from may 1...*blush*
Secondly if i were to have a calendar control on the form that may 1 is pointing to (at the moment I dont) how do I get the calendar contol to reflect that it is may 2 and not may 1??
this is not for a web site it is for a tire shop here in town, and it is the first project that I am doing..so it is kind of important to me.

I'm trying to figure out how to make a dynamically scaling/resizing 2d chart on a form as my 1st trip into graphics. Most 3rd party addons/DLLs are of no use to me as the bank I work for is unlikely to allow any of those to be used in my projects.

I want to have a button on my form that will close the form itself and then reopen itself essentially refreshing the form. i have read several posts about this topic and most people say use the hide and show functions but i don't want to hide the form i want to close it. I have also tried to use the form1.refresh thing and that doesn't work either.

I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmColProcessing as shown below, but it doesnt Refresh FrmPracDetails form.

My environment: VS2008/VB using Data Sources (datasets, binding sources, table adapters) to interact with MS Access 2007 database.
My application: A Master form displaying a 4-level hierarchy of data using listboxes instead of grids. Data source for each listbox is a query containing child table data and a stub (foreign key provided by a cross-reference table) to parent record.
Processing: User double clicks Listbox on the Master form to call a popup form bound to child table (to enable data entry). When popup SAVE is clicked, new data is saved to Child table and a new cross-reference record is created to enable future Parent-Child connections. Changes are posted directly to the underlying Access 2007 database.
Problem: On return to Master form, impacted Listbox does not refresh even though I've done another tableadapter.fill on the control. I have been unsuccessful over the last week in finding ANY way to refresh the set of queries that supply data to the Master form or the form itself. When I close/reopen the Master form, Listbox includes the new record.
Need: a way to refresh the Master table without closing/reopening.

I have a Main form (a window form) in VB.NET which has a Combo Box to display a list of countries. A sub form activated from a "Button" on the Main form allows users to add Countries to their list. But After Adding a new entry the Combo Box on the Main form does not show the update (while it is still open). I have to exit the main form and relaunch it to see the update.
The populate function in shown below. I call this method after adding new countries but still; not good. I have used Invalidate function of combo box but of no use as well.
Public Sub PopulateCountry()
Dim rsLocal As New ADODB.Recordset

I have a form that remains open while running an application. The user can open multiple instances of a form to edit customer information. After editing and exiting an instance of the Customer form I want the form with the buttons to refresh and show the changes. Basically the form show the availability of storage units, green rented, yellow available and red is late payment. Right now I am acheiving this by closing and opening the button form when I exit the Customer form. This works but there must be a better way to do this.
