Blazor - How to show a toggle switch in ListView cells

Hello,

I reviewed your code and can see that parameters are incorrectly passed to the Razor Component that you implemented. You handled the CheckedChanged event as follows:

C#
<DxCheckBox Checked="@ultimosValores.Accion" CheckedChanged="@((bool value) => CheckedChanged(value))">Silent Mode</DxCheckBox>

However, this code is never used, since the CellDisplayTemplate.Create method does not reuse this markup - it creates a new DxCheckBox item. The Create method should return the current Razor Component - CellDisplayTemplate. Here are some examples:

Implement a Property Editor Based on a Custom Component (Blazor)
Use a Custom View Item to Add a Button to a Detail View'

Please see how the Create method is implemented in these examples. As you can see, it passes the received object to the created component using the component's parameter. You can pass the received UltimosValores object to your CellDisplayTemplate component in the same way.

To bind the Accion property to the control's value, use the @bind- keyword with the Checked property, or define the CheckedChanged handler. Please refer to the following help topics for additional information:

In addition, you need to turn off the default click handler that shows the clicked object's DetailView: Xaf blazor create clickable links in list view.
