when i try to resize one column in the grid every other column is resizing too
i've set ColumnWidth parameter in RadzenDataGrid and Width for every RadzenDataGridColumn.

You might need at least one column without width.

doesnt work
this is my code now, i removed ColumnWidth and now doesnt flicker when try to resize but continues to resize every column

<RadzenDataGrid Style="height:calc(100vh - 130px);" @ref="gridItems" AllowFiltering="true" AllowPaging="true" ShowPagingSummary="true" PageSizeOptions=@(new int[]{ 50, 100, 500}) AllowSorting="true" Data="@vItem" TItem="vItem" SelectionMode="DataGridSelectionMode.Single" RowSelect="@RowSelectItem" PageSize="50" AllowColumnResize="true" AllowColumnReorder="true">
    <HeaderTemplate>
         <RadzenRow>
             <RadzenColumn Size="2">
                 <RadzenStack AlignItems="AlignItems.Start">
                     <RadzenColumn>
                         <RadzenButton Icon="Refresh" Click="@gridItems.Reload" Variant="Radzen.Variant.Filled" Style="padding-bottom: 8px" ButtonStyle="Radzen.ButtonStyle.Secondary" Shade="Radzen.Shade.Default" />
                     </RadzenColumn>
                 </RadzenStack>
             </RadzenColumn>
             <RadzenColumn Size="10">
                 <RadzenStack AlignItems="AlignItems.End">
                     <RadzenColumn>
                         <RadzenButton Icon="add_box" Text=@L["Items.Add"] Click="@AddItemClick" Variant="Radzen.Variant.Filled" Style="padding-bottom: 8px" ButtonStyle="Radzen.ButtonStyle.Secondary" Shade="Radzen.Shade.Default" />
                         <RadzenButton Icon="edit_square" Text=@L["Items.Edit"] Click="@EditItemClick" Variant="Radzen.Variant.Filled" Style="padding-bottom: 8px" ButtonStyle="Radzen.ButtonStyle.Secondary" Shade="Radzen.Shade.Default" />
                     </RadzenColumn>
                 </RadzenStack>
             </RadzenColumn>
         </RadzenRow>
     </HeaderTemplate>
     <Columns>
         <RadzenDataGridColumn TItem="vItem" Property="I_Code" Title=@L["Items.Code"] Width="50px"/>
         <RadzenDataGridColumn TItem="vItem" Property="I_Name" Title=@L["Items.Name"] />
         <RadzenDataGridColumn TItem="Item" Property="I_Revision" Title=@L["Items.Revision"] />

PS
i was with version 5.2.6 and upated to 5.2.8

Check our forum FAQ on how to improve your post - it's impossible to read anything nor to test it.

sorry i didnt fount how to add code block
how is now?

Here is an example base on your code that works:

@using RadzenBlazorDemos.Data
@using RadzenBlazorDemos.Models.Northwind
@using Microsoft.EntityFrameworkCore

@inherits DbContextPage

<RadzenDataGrid Data="@employees" TItem="Employee" AllowFiltering="true" AllowPaging="true" AllowSorting="true" 
    AllowColumnResize="true" AllowColumnReorder="true" ColumnWidth="300px">
     <Columns>
         <RadzenDataGridColumn TItem="Employee" Property="EmployeeID" Title="EmployeeID" Width="50px"/>
         <RadzenDataGridColumn TItem="Employee" Property="FirstName" Title="FirstName" />
         <RadzenDataGridColumn TItem="Employee" Property="LastName" Title="LastName" />
    </Columns>
</RadzenDataGrid>

<EventConsole @ref=@console />

@code {
    IEnumerable<Employee> employees;
    EventConsole console;

    void OnColumnResized(DataGridColumnResizedEventArgs<Employee> args)
    {
        console.Log($"Resized {args.Column.Title} to {args.Width} pixels");
    }

    protected override async Task OnInitializedAsync()
    {
        await base.OnInitializedAsync();

        employees = dbContext.Employees;
    }
}

You can test it in our demos - they are editable.

Tested in your demos as you suggested, but the effect was the same :frowning:
Animation

Here is what I see:

I think i spot the problem/difference
When the browser is maximized my problem occurs,
but when i unmaximize it works as you showed
so the problem is i dont have enough columns for my space?

What's your browser? I'm using Chrome and there are no differences if the window is maximized or not.

i use vivaldi as daily driver, but have chrome, edge and firefox.
the grid is working the same everywhere
Here is a demo with chrome
Animation3

so to fix my problem i have to set really high value for ColumnWidth and set the desired values for the columns expect 1 that will be stretch to the max
