.net - Datagrid Update Checkbox IsChecked On DataGrid.Refresh()?
Mar 20, 2012
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 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 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 an DatagridTemplate Column containing an Checkbox which through an converter gets checked when a property on my ItemSource is "J" and unchecked when the property is "N".This works, but now I want the property to be set to "J" if I select the checkbox or "N" when I deselect it.
My Column:
<local:JNConverter x:Key="JNConverter" />
<DataGridTemplateColumn Header="">

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 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'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?

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 working with Vb.net. See the code below; I have the following problem - when I click the checkbox (Cells(3)) the value remains 0.00 in Cells(4) unless I click another checkbox is when Cell(4) gets populated with the value from Cells (5).
What I want it to do is when cells(3) is checked, Cells(4) should be populated instantly with the value from Cells(5). Rather than still show 0.00 until another checkbox is clicked. I think th eproblem is in the eventhandler as highlighted

I am limited to using ASP .NET 1.1, as for this environment I cannot upgrade to 2.0 or beyond Essentially, I have a very simple datagrid that has a checkbox in one of the columns, which is a template column...the code for the datagrid is this:
<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
[code]....
Now, my issue is that when I set cbStaticRolling to the CheckBox control through FindControl on the e argument, it seems to set the variable okay, but doesn't seem to be setting the right one, or setting it properly, because "Checked" property is false regardless of whether I check the box or not?

I have a tbl called tblProjectpatients which also has 2 fields Yes and No (these have the data type - Bit).
These two fields have been populated with false and true values.
On my form, I have a datagridview which is populated with various values from tblProjectpatients.
The problem am facing is that the checkbox's for Yes and No on the datagridview are empty at runtime eventhough at the backend they have either False or True values.
I am expecting the checkbox showing on the datagridview to be either checked or Not Checked depending on the True or false values.

I haven't seen a related thread (yet)I have a VB windows application that uses a datagrid to display a text column and a checkbox column. Only one row in the display can have a checkbox entry = true. If a checkbox is selected, the app is to search the rows and all other checkbox entries are to be set to false.My event handler is: Private Sub dgMember_CellContentClick(ByVal sender As System.Object, ByVal e As ystem.Windows.Forms.DataGridViewCellEventArgs) Handles dgMember.CellValueChangedI first had to have this handler code check a flag and exit if true (when initializing the display) because it was called for each row during initialization.

Interesting problem. I have a datagrid with several columns which are bound to an Access database. Here's the situation...I'm concerned with the 3rd column.This is what I'd like to happen... when the 3rd column(is a checkbox) is checked then column 4(TIME_USER) would be populated with the current time
Basically, this application is meant to keep track of tasks that the user has to do at a certain time of the day. When the user checks the checkbox it would record the time in the database for that task as to when they did it. I found some code from a forum that i changed to fit my needs, but it's not working.

I'm writing an Windows Form Application and need to add an unbound checkbox to a datagrid.The datagrid displays the fields of an Access 2007 table and I need the checkbox to give the user the option to select/deselect any of the records shown in the datagrid. After the user clicks on a button, the application must read the whole datagrid to detect what records were chosen by the user and process each one accordingly.I tried using TableStyles but as this new column is not part of the database, it won't work.
