I've installed visual studio c# express, .net SDK 2.0, SQL Server
Express, created a table in the SQL database and filled this with some
data-rows. I dragged the database-table from Data Source-pane to the
Form-designer to created a datagridview-form. When I then build and
run the program the datagridview is nicely filled with database-data.
But when I add or modify the data inside the datagridview in the
running program the database...

I had a SQL server 2005 table in which I noticed I mispelled a column name.
I changed the column name in the sql server table but after that, in the UI
fortm using the table, the dataset control bound via a binding source and a
table adapter to a datagridview no longer recognized the changed column name
and kept giving me an error on that column, evidentlty I expect that is
normal.
But only way I found to fix and see my changed column was...

We have been noticing that questions on vs.2005/2.0 don't appear to get much
in answers so I'm reposting some questions posted by some of the programmers
here in our organization that never got answered...
In 1.1 we always did our own myDataAdapter.fills and we liked that control
for lots of good reasons. Now the new DataSource (or is it a
TableAdapter:Dataset) automatically fills the Gridview. How can we control
that fill?

Hi,
I am struggling with two way databinding in WinForms and the DataGridView.
I am binding to business object classes (rather than datatables). If I
have a collection of these business objects that is the datasource of a
DataBinding that is bound to a DataGridView (WinForms) then I was expecting
that any change to the data would be reflected in the DataGridView (in other
words I was expecting the 2 way databinding to actually...

Hi all,
I have a DataGridView control in my Windows Forms application. I am
binding it to a DataTable in another assembly. The name of the assembly is
ActivityListDALC. I want to bind my grid to
ActivityListDataSet.ActivityListDataTable in this assembly. I selected this
DataTable in the grid's Properties window and it added a component called
ScheduledCallDataTableBindingSource to my form. I can also see the column
names in my grid. But...

I have a DataGridView displaying data from a DataSet. To the right of that
I have a custom user control which displays one of the data set fields.
The custom user control is bound to the data set object and displays the
data correctly when I move from row to row.
The problem I am having is the data set always reads the data back and
considers it change even when it's not. I am looking for how to change the
following code so the...

Hi,
My problem:
When the cursor is on a given row in the DataGridView, the data in the row
has to be shown in TextBoxes underneath the DataGridView. the user must be
able to edit in the Datagridview, or in the textboxes. The text in these
textboxes and the datagridview has to be synchronsied at all time. So if the
user types "a" in the Name-Column, the "a" has to appear immediately in the
Textbox etc.

Please help me with this databinding scenario:
Suppose I have a "Person" class, and that users populate Person objects in a BindingList collection through a datagridview. Users save the Person objects to the database when they click the save button.
When the user starts the app, a person datagridview is populated with Person objects in the BindingList. The user subsequenly deletes one of the rows in the table, deletes the Person object. ...

I have set up a datagrid on my form with six columns. I want to capture the
data from six textboxes on the form and add them to the datagrid. All the
info I can find about this is with datatables and databinding. I don't want
to databind this, this is only a repository for data until the user clicks
the save button. Then I will iterate through the grid rows and insert the
data. Does anyone have code to populate a gridview from...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
