How do I open the entity history change modal from my index page in blazor?

I tried:

@inject EntityChangeHistoryModal EntityHistoryModal;

await EntityHistoryModal.OpenAsync(EntityFullName, entityId.ToString());

I get a Null reference exception.

    Hi,

    You can try this:

    .razor file

    <EntityChangeHistoryModal @ref="EntityChangeHistoryModal"/>

    .razor.cs file

    protected EntityChangeHistoryModal EntityChangeHistoryModal;

public async Task OpenEntityChangeHistoryModal(Guid id)
{
  await EntityChangeHistoryModal.OpenAsync(EntityTypeFullName, id.ToString())
}

    That worked - thank you!

    Is there any way to modify the contents of the modal?

    Hi,

    You have to replace the component: https://docs.abp.io/en/abp/latest/UI/Blazor/Customization-Overriding-Components?UI=Blazor
