Problem with ColumnChanging in the BeginInit()

I am adding some field validation throught column changing with partial
classes. I am debugging it and when it hits

this.ColumnChan ging += ValidateColumn;

It never goes to the method

void ValidateColumn( object sender, DataColumnChang eEventArgs e)

Any ideas why? Code is below!

Public partial class Bassco

{

public partial class bcr_price_range sDataTable

{

public override void BeginInit()

{

this.ColumnChan ging += ValidateColumn;

}

void ValidateColumn( object sender, DataColumnChang eEventArgs e)

{

if (e.Column.Equal s(this.MinColum n))

{

if((decimal)(e. ProposedValue) 5)

{

throw new ArgumentExcepti on("Min cannot be less than zero", "MIN");

}

}

}

}

}

User enters values into an asp.net form and clicks a button. Retrieve dataset from...

I currently use the datatable.ColumnChanging event to call my data validation method in a bound datagrid (Windows not Web). This is causing me problems since the user must click away from the datagrid or select another cell to run the validation. Is there another way to call the validate of a bound datagrid that begins when the user first starts to type rather than when the cell is changed or the datagrid loses focus?

Also I get lots of member not found errors, these however don't stop me from...

Hello, I'm using typed dataset for databinding to windows controls and I'm having some problems. I'm trying to move all business logic to datatable column_changing events and the problem that I'm having is when I change some other column, control value doesn't update immediately until I call endcurrentedit on bindingmanager which doesnt happen until user click update button.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

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,...
