Hi Team,

We have done migration from 10.2 to 11.2.1 angular for multiple widgets. In new version of angular application multiple customized widgets.

Please see below design page for customizable dashboard. we have added two customized widgets. it's showing same result.

we have added two properties uniqueWidgetId and customAccountNumber in gridInformation.

on the basis of these properties we need to initialise the customized widgets. we want to send uniqueWidgetId and customAccountNumber to the customized widgets component from customizable dashboard component. how to send these id's to customized widgets ?.

    Hi @aslam.loni

    It is not passing uniqe id to the widget in your version. It is implemented here https://github.com/aspnetzero/aspnet-zero-core/pull/4488/files#diff-4193057d53f587480db3ccfd1a5ed167d0b46371461c12ac9782e0012768b809R174.

    Hi @musa.demir

    I tried to implement code from above github link but it is not working as expected. Do you have any other solution or code to refer?

    Hi @musa.demir

    I have github access to this URL. I have read that code and implimented in our sourc code. It's not working as we want in our application. Do you have any other solution. Our release is stuck due to this issue. Looking forward to hear from you as soon as possible.

    Please see below error during execution

    Hi @aslam.loni It seems like you forgot to add some part of code. Can you please verify that you implemented those:

    Hi @musa.demir,

    Essentially we would like to pass Widget.SomeProperty ( here Widget refers to the Widget Class defined in service-proxies.ts ) from customizable-dashboard.component.html to widget-{WidgetName}.component.ts

    Can you please explain the steps needed to achieve this? We are not able to understand the relationship between the code shared above and what we need to implement exactly.

    Hi @aslam.loni

    I think this is not supported at the moment. You can create a base widget and create different implementations of the base widget with the parameter you want to pass for now. For example, you may have BaseSaleWidget and CarSaleWidget and ServiceSaleWidget etc...

    Hi @ismcagdas,

    Unfortunately this would not work for us since we want to add the same widget multiple times to the dashboard and bind each instance to a specific value. We want to then retrieve the data for the widget from the database using this specific value.

    Can you please suggest any alternative way to implement same or similar functionality?

    Hi @aslam.loni

    Could you share how you area planning to add those widgets to page ? Could you share the real life usage scenario ? If I can understand it better, maybe I can offer you another option.

    Hi @ismcagdas,

    We are building an Accounting and Financial Modelling related system. Hence, on the dashboard we have widgets that can be mapped to specific accounts selected by the user. The widgets will then show data with various filters such as Monthly, Quarterly, Yearly, under different budgets, scenarios, etc. Here, it is important to note that every user may want to add different accounts on their dashboard depending upon their role in the organization, type of the organization, organizational goals etc.

    Hence, we need to create a Custom Account Widget that can be mapped by the users to any account of their choice. Since there can be multiple accounts being watched, it would be useful to have multiple instances of this widget bound to different Account Numbers.
