Can't Get Form Controls To Refresh

Jan 30, 2012

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()
With dynTextBox



Refresh A Form's Bound Controls?

May 20, 2010

I have a windows form with multiple TextBoxes that are bound to a DataSet of type XML. I load text into the textboxes using DataSet.ReadXML method in the form's load event.

I have another windows forms application which edits the XML contents in that XML file.

How do I force the textBox controls on this form to refresh once the XML datasource file items are changed?

DB/Reporting :: PopUP Form Refresh Combobox On Parent Form

May 31, 2008

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?

Form Does Not Refresh?

Jun 12, 2006

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.

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?

Refresh A Form In VB?

Jun 3, 2010

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.

Controls Not Return All The Child Controls For The Form?

Apr 15, 2010

I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.

Force Form To Refresh?

Sep 28, 2010

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.

Refresh A Datagrid From A Different Form?

May 26, 2011

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.

Once I delete record I want the form to automatically load with new / updated data. This form fetches data from MS Access using OLEDB.

Form Refresh Or Make Duplicates

Apr 29, 2010

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 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 it is kind of important to me.

Refresh Another Form On Button Click?

Aug 11, 2009

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.

Refresh Bound Form After DB Insert?

Jun 12, 2009

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.

Refresh Combo Box In Windows Form?

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.

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.

.Net WinForms Form OnPaint() Transparency Refresh?

Aug 13, 2010

I'm trying to write some toast-style popup notifications (similar to Growl) which should appear next to the system tray and stack as appropriate.I can handle the instantiation/location/etc... but I want to add a capability for non-rectangular toasts. I'd also like to have Alpha transparency so a semi-transparent background PNG on the toast form would blend with the desktop or windows behind it.

So... To get the obvious out of the way: Form.TransparencyKey is not sufficient for my needs as it's an all-or nothing transparency effect I want to get 50/50 foreground/background in some places, 0/100 in others, 100/0 in yet others etc.My initial approach is to override the OnBackgroundPaint() method, comment out the call to MyBase.OnBackgroundPaint and use the graphics object in the eventargs to draw exactly what I want to a form.This seems to work to start with - at the moment, I'm just drawing some rectangle for testing purposes so a PNG may present new difficulties but I haven't got there yet.

What I haven't been able to accomplish is updating the graphic - The first time the form is rendered, it shows perfectly as I'd expect (no border, just some rectangles floating on a desktop). If I move the windows behind the transparent window, the transparent window doesn't update/re-paintI believe that I need to be calling Me.Invalidate() to force a re-draw but am unsure when I should make the call - How do I know a window behind me has changed its' contents?

Edit: I tried putting a Me.Invalidate() inside a timer just to test how the redraw happens - it seems that it does trigger a re-draw but the re-draw opccurs OVER the existing form background - ie an area that was originally 50% opaque is now 75% opaque (50% + 50% of what was there before)So, after a couple of Invalidate()s, my form is showing as a black box - I need to clear the background of the form before re-drawing but Graphics.Clear(Color) seems to simply do a fill with the specified color - and obviously for the purposes of this question, Colors.Transparent doesn't really mean transparent - It seems to be a trick used when rendering the window to "show contents of control beneath this" which just doesn't work when we're dealing with the form itself?

Form Don't Auto Refresh When Change Certain Values

Dec 23, 2010

i 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]
