Our organization has an app that we're porting from .NET/WPF to React. We have several grids, that utilize this:

```

using System;
using System.Collections.Generic;
using System.Data;
using System.Drawing;
using System.Windows.Forms;
using Telerik.WinControls;
using System.Configuration;
using System.Data.SqlClient;
using Telerik.WinControls.UI;
using Telerik.WinControls.Data;
using System.Data.OleDb;
using System.Linq;
using System.Threading.Tasks;
using System.Web.UI.WebControls;

using System.ComponentModel;

```

Instead, I'd like to use KendoReact.

Before I rewrite the entire thing in NextJS/KendoReact, are there some tools and techniques that I could use to save time?

I'm trying to make my gridview box column show the dropdown tick without having to click

<telerik:GridViewComboBoxColumn Header="Active" DataMemberBinding="{Binding EnableCase}" UniqueName="Active" ItemsSource="{Binding Activeops}" DisplayMemberPath="Describe" SelectedValueMemberPath="ID" />

The Dropdown only shows up when i click on the header

I would like to indicate/emphasize cells selected for the action.

Example scenario:

1. select 2 cells in the grid;

2. perform some action after pushing separate button "Process selection";

3. now i need to show those previously selected 2 cells despite of clicks on other grid cells or loosing focus on the grid.

There is another button "View All" which will reset grid and clear all "permanently" selected cells.

Looking for suggestions to implement such behavior. Thinking about changing background color, making cell text bold, disabling cells. Any ideas?

CellStyleSelector sample from xaml_sdk demonstrates a static custom cell selection in columns overriding xaml styles. I need to make it dynamic: select cell, perform action, mark cell as processed, select another cell, process it, unmark previous cell, mark new one as processed.

Thank you,

Gennady

RadGridView has slow performance if grid with hierarchical data has huge children capacity (e.g. 2000 children for each node).
I'm waiting a lot of time for expand node, very slow scroll, application brings up a lot of memory.

This is odd, I am using the latest SP1 libraries and have followed all the steps and only see this in the WPF application. The Activities column should look like a drop-down combo box when the green checkbox is showing. Obviously, I am missing something, but not sure what it is. I hope I can look at it fresh in the morning and figure it out, but if there are tips, please let me know.

My XAML has this definition for the column:

<telerik:GridViewComboBoxColumn Header="Activities"
                                Width = "271" 
                                DataMemberBinding = "{Binding Description}" 
                                SelectedValueMemberPath = "SicCodeValue"
                                DisplayMemberPath = "SicCodeDescription" IsLightweightModeEnabled="true" IsComboBoxEditable="True">
</telerik:GridViewComboBoxColumn>

and I set up my itemssource via code using the following line on data load:

(this.myList.Columns[2] as GridViewComboBoxColumn).ItemsSource = (ViewModel as MyViewModel).SicCodes;

Hello.

I'm making it using MVVM.

Thanks.
