Original Pull Request: https://github.com/radzenhq/radzen-blazor/pull/1550

State: closed
Merged: Yes

Creates a more elegant solution for #1543.

Adds an IsInEditMode Func on RadzenDataGridColumn that allows you to override when to show the EditTemplate, with a default Func that evaluates to false so the previous behavior can proceed as expected.
Enhances the proper codepath in RadzenDataGrid to evaluate whether the EditTemplate should be rendered.
Enhances the InCellEditMode demo with a structure that would be more in line with customer expectations, including:
- comments on things to pay attention to when making changes
- comments on where to make changes for your own custom behaviors
- some minor variable name fixes
All unit tests pass

Simple example:

        <RadzenDataGridColumn TItem="Order" Property="ShipName" Title="Ship Name" IsInEditMode="@IsEditing">
            <Template Context="order">
                <RadzenText Text="@(order.ShipName)" />
            </Template>
            <EditTemplate Context="order">
                <RadzenTextBox @bind-Value="order.ShipName" Style="width:200px; display: block" Name="ShipName" aria-label="Enter ship name" />
                <RadzenRequiredValidator Text="ShipName is required" Component="ShipName" Popup="true" />
            </EditTemplate>
        </RadzenDataGridColumn>
