View 1 RepliesI am trying to add a checkbox column to a DataGridView in a simple window forms application.
I am pulling back some data from a database using ADO.NET, putting into a datatable, and then setting the datagridview datasource to the datatable. I then want to add a checkbox column as the second column. So far I have this code that seems to work:
' Code here to connect to database
Dim da As New SqlDataAdapter(cmd)
Dim dt As New DataTable
[Code].....
This code 'works' and I get MyDataGridView to show the data with the checkbox column in the correct position in the table.
However, for some reason, I cannot check any of the check boxes in the DataGridView? I have tried lots of things (e.g.altering the readonly state of the column) but cannot get it to work.
is my main form.and frmpayable is frmmain's child from.in the frmpayable my code is
Dim frmreleasing As frmPostap
frmreleasing = New frmPostap(Me, release_record)
frmreleasing.MdiParent = Me.MdiParent
[code].....
Can a data grid in another open form be refreshed by calling a sub routine? This app has a form with 2 data grids. When the user double click on one of the grids another form is opened that shows data details. After the user changes the details the user clicks a save button. We have placed this code in the Closing event of the the details form.
Private Sub FormParents_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
FormParentsAndStudents.RefreshDataGrids()
End Sub
[Code]...
Can you tell us what additional coding is needed to refresh this data or if we are using the incorrect place to call this code from within the details form?

Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime
I am developing a software using microsoft visual studio basic 2010. I used a datagridview control to display a list of data from product table. What I want to do (actually I am not sure how to do it, or is there a way to do it), when I choose one of the value in one of the column inside the table, I want it to open a form that contain data(details) based on that value.
How to do it? How to call the value that I pressed, so it can be used to open a new form containing the details of that value
Example of the data: (the "system" column) SYSTEM
topaz
nex1300
Nec
If I pressed "topaz" system, it will prompt me to a new form containing the details of that "topaz" system.

I've got a asp.net gridview and inside of the grid view I have a check box at the header of the grid view like so: [Code] This gives me a nice little check box at the top of the grid view, the event OnCheckedChanged calls a function called SelectAllRows that looks like this: [Code] So if I click this header checkbox it checks all of the items in the gridview, and if I uncheck it, it unchecks all the items in the gridview. This works fine...but what doesn't seem to work is if the page loads up and I check the grid view header checkbox to true and it selects all the items in the gridview, then i click a button such as a DELETE button that calls some server side code. That code simply loops through the grid view and checks if the checkbox has been checked, if it is it calls code to delete an item.
