Passing data from MudDialog back to parent

[DoubleD82]

Hi,

I am struggling to find an example of what I need to achieve. If anyone would be so kind as to point me in the right direction, it would be greatly appreciated.

On my page, I have a button that opens a MudDialog which renders a MudTable with some data.
What I need to do is to then select an item in the table and then on double click or button click, send the selected row data back to the parent page and populate the necessary fields with said data.

This is what I use to pass parameters, launch and receive an object back from a dialog

private async Task OpenDialog()
{
    var parameters = new DialogParameters { ["DialogParameter"] = objectToPassThrough};
    var dialog = dialogService.Show<NameOfYourDialog>("Title of the dialog", parameters);
    var result = await dialog.Result;

    if (!result.Cancelled)
    {
          result.Data //This will be your received object
          //Do what ever you need to with the received object
    }
}

Then from your table within your dialog you can add a button to the row or a on row click event (not sure about double click) to run what ever code you need and then close the dialog with this:

MudDialog.Close(DialogResult.Ok(ObjectToPassBack));

I am by no means and expect and new to C# and Blazor so take this as you will. Hope it helps!

Thank you very much. I have been dealing with this problem for a long time.

FYI result.Cancelled is obsolete, use Canceled

I would also add that it's better to use ShowAsync otherwise the IDialogReference will be null in case you need it before the dialog result.
