gridcontrol | Networked Process Manager to execute functions

Shortly,

Here's a schema

User Table

Category Table

1. A user have a categoryID
2. All I need to populate a GridControl with User_ID, CategoryID, CategoryName
3. Note that CategoryName is only belongs to second table (Category Table)

What I do Is:

Create Models (User, Category) Note that primary key is composite so it must be structure https://supportcenter.devexpress.com/ticket/details/a2615/xpo-how-to-map-persistent-objects-to-database-tables-with-compound-or-composite-multi#

I have a C# usercontrol with a DevExpress GridControl in it. When I use a style for the GridColumns in the local xaml file like below, everything works

Winform has 2 grids. I display related tables from the SQL Server database to them.

Here is the code:

I have a .net, C# Windows Form project. I'm using DevExpress 19.1. On my GridControl, I have conditional formatting for when a column is less than 0. I want the cell to be highlighted red when the value is less than 0, but it's not working. I've tried using an expression, a condition and value, applying to just a column, applying to the whole role, but I never get the highlighting to work. Can someone tell me what I'm doing wrong?

Here is how the rule looks liked in code:

I have a folder with multiple text files in it, each text files has about 14 lines of text. I would like to add all text files in that folder to a gridcontrol/gridview in vb.net.

My current code only adds 1 text file instead of adding all. any help would be greatly appreciated.

I have an object "User" which contains ICollection "Phone". I want to display them on TableView-GridController of DevExpress in one column as given below:

So i create popup Edit form, and i want to display connected rows in this popup also. For this i use Repeater with datasource and update datasource select comand each time when user opens Edit form:

Init of edit form:

I want to use LiveBindings to connect a database table to a StringGrid, but I don't want to use the LiveBindings Designer, I want to do it manually via code. The documentation is in my opinion nearly not existing, which makes it more complicated than it should be.

I created a FMX application with my Delphi 10.3 and this is the code I wrote to do all I need:

I am using a WPF Devexpress GridControl with dynamic columns generated. UI Rendered all columns one column per month from years(let say 2020 to 2070). So I am trying copy values for a row from excel which has values from 2020 to 2061 which is approximately 500 values/cells. But the default TableView.OnPaste() only copies 242 cells. I tried various ways to figure out why is that? But no use.

I disabled virtualization, tried to scroll all the way to make sure columns are rendered everything is there and another interesting thing is:

TableView Evnent: ClipboardRowCellValuePasting=void OnClipboardRowCellValuePasting(object sender, ClipboardRowCellValuePastingEventArgs e)

this event is called for all 500 cells but after 242 cells the values are blanked. So its definitely in the paste implementation it is setting values to null after certain limit.

So can anyone suggest how to fix this?
