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.

I have a datagrid view control that is tied to a dataset. so when the Dataset is updated with a new record,It shows up in the grid. The problem is, I have to minimise the window or some how force a re-paint on that window to see the updated grid.
how to call that refresh? Form.refresh and form.grid.refresh did not work.

I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs)
Dim _CB As CheckBox = DirectCast(sender, CheckBox)
Dim _ID As Integer = _CB.Tag
Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice

I have a Silverlight Datagrid who's DataSource I refresh every 5 seconds.I would like when the grid refreshes, for the focus to be on the last row, not the first.I have tried setting the SelectedIndex property of the grid to be the last row, but it did not work.
The details:I am binding the DataGrid to an ObservalbleList(Of MyObject) property on it's ViewModel, and the SelectedIndex is also a property on the ViewModel. Both properties raise the property changed event (able to witness this working by seeing the DataGrids DataSource clearly changing, but the SelectedIndex is never set.I have read reports that setting the SelectedIndex on a DataGrid is a known issue, but have not found a work around.

I 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?

i'm having with a problem to refresh my datagrid view. I have 2forms and a database create from msaccess2010. This programme is too simple, in form1 requesting a costumer name and save button. After being saved, it'll show form2 which is database in datagrid view. Yes, in first save the name of costumer are being shown there but after i close (which is 'hide' actually,i cant use 'close' due to particular reason) and reinsert the data in form 1 and save it,the second data are not being shown in form2. So my question is,how can i make the data refresh(by form load or button refresh,any of them)?

Let's say that I have a windows application in which I have a form with some controls that are bound to a dataset. A DataAdapter or TableAdapter fills the dataset on form load with a large number of records and user can navigate and change the details for each record. This works fine ... but this app runs on a network. And let's say meanwhile you've loaded your form and you're navigating through it (for half an hour let's say whithout saving changes or reloading the dataset) another user modifes the data and updates the database but as long as you have your application running you can't see those changes !!! what is the method to know whether the database has been updated or how to refresh the datagrid view with the new changes updated by other users while the application is running?
code is

I'm trying to refresh the datagrid after using the SQL UPDATE statement. The data changes physically in the database but the datagrid is not affected. The data is changed only after i restart the program.
How can i get the datagrid to refresh or update? I have tried using, among other code, the refresh() method, but it does not work.

I have a big problem regarding MdiChild. My problem is that I have 3 forms loaded;
Form1=Mainform / mdiParent
Form2= Display the Datagrids
Form3= This is where I let the user input the necessary fields like Lastname, Firstname,Age,etc...
My problem goes like this, Form3 is the child of Form2, Form2 is the child of Form1 and I call them one by one like this:
//form1
Form2.MdiParent = this;
Form2.Show();
[code]....
I want in the Form3 to save data and refresh on my datagrid on Form2 so that every data that I encoded in Form3 will reflect in Form2. I let the Form3 close everytime there is data entered but my problem is that the data that entered doesn't reflect in my datagrid.

I am adding records to a database from a modal popup. After hiding the modal popup, the page has not been refreshed (even though I have Re-bound the controls). I have reviewed a few postings on the web about this but the solution still evades me. I have attached my code after removing some of the extra detail.
It seems I need to cause a postback, but I don't know what needs to be changed. Some posts have talked about the extender being misplaced.<asp:Content ID="Content1" ContentPlaceHolderID="Head" Runat="Server">
<div class="divBorder">
<asp:DataGrid id="dgrSessionFolders" runat="server" BorderWidth="2px"
BorderStyle="Solid" BorderColor="#C0C0FF"

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 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'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

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.
