Hello
I have hit a major road block when it comes to building my dynamic datagrid. To make a long story short I need a dynamic datagrid because my connection string could change and I need the datagrid to handle that. First I tried to create my datagrid by leaving the auto-generate columns equal to true. This worked fine except that when my user wants to edit a line I do not want them to edit column 1, only column 2. I could not find a...

Hello
Does anyone know how to display data from a data source such as an
array or SqlDataReader or XML etc within an HTML table whose number of
columns can change according to the value of a variable ?
This is one thing that XSL is brilliant at but I can't find a nice
..Net solution
The following is how it can easily be achieved in XSL.

The following code snippet creates a DataSet on the fly which is then passed to a DataView so that the DataSet can finally be viewed in a DataGrid control:
'Create the empty DataSet
Dim objDS As New DataSet("MyDataSet")=CreateDataSet()
'Create the new table & add columns
Dim dTable As New DataTable("Users")
dTable.Columns.Add("ID",System.Type.GetType("System.Int32"))
dTable.Columns.Add("FirstName",System.Type.GetType("System.String"))...

What I am attempting to do is import an Excel Workbook and display the
worksheets in a datagrid dynamically.
I am very close to getting this to work. I have to this point
successfully imported a single worksheet into a dataset. I successfully
built a dynamic datagrid. And I did successfully bind it to the
dataset. Then I added the datagrid control to a PlaceHolder. The first
worksheet displays beautifully.
The next step is to allow...

I have been trying for the last two weeks to display a dynamic DataGrid. The
data that I'm pulling from a SQL Server DB will have whole columns that will
be either NULL or 0. I want to display only the fields that have actual data
in them and either not display or hide the columns that have NULL or 0
values. As an example, one page may need to display a total of 5 columns and
another page may need to display three columns based on the...

Greetings,
I have a gridview which is sitting on a multi view control (witin a view),
and it is bound to a dataset which I dynamically apply to the control within
asp.net page. The problem is that I can't seem to resize my dataview's
columns which are auto generated. Is there a way to do this? I have tried
several different things, but I can't seem to get at the column collection to
change the widths?

Hi
I'm having some problems getting a dynamic LINQ query to work on my DataSet. The idea is that a user selects certain criteria, and then the LINQ query filters through the dataset making the requested changes.
The table I am trying to alter is called RawData, this is defined in a DataSet but has no data columns as these aren't known until some data is imported. As part of my import routine it automatically creates the correct columns...

Hi all
I think this question was discused quite often before.
But maybe some "good-brain" has a great idea ... :-)))

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
