Do you have any working sample project using this dialog built using VB in VS2013 or VS2017?

I have been working on this for a couple of days but when the dialog.show is called in javascript nothing happens.

This is true in IE and Chrome.

Can you create a new project following the instructions at https://es.infragistics.com/help/aspnet/webdialogwindow-displaying-the-webdialogwindow-client-side?

one issue is that I have never been able to get this function to work as shown in the documentation.

function btnDialogWindow_onClick(){
        var dialog = $find("WebDialogWindow1");  //Find here does not return anything.
        dialog.hide();
}

But this will find the dialog

function btnDialogWindow_onClick() {

 var dialog = $('[name=WebDialogWindow1]');

  dialog.hide();

};

And this is not valid either.

<td align="center" valign="middle">
        ...
</td>

Should be

<td style="align-content:center"></td>

Thanks
