Lightning mainly focuses on the user experience on the web and mobile interfaces. So, most of the scenarios we should need to know the information of the browser to align the design with respect to the device browser. In this post, I would like to discuss, how we can detect the browsing device information in a lightning component.
I have uploaded an attachment (salesfiorce_migration_guide.pdf) to an opportunity record from classic salesforce. The uploaded document record has the following actions where ‘view’ action is a link to download the file.
Next, uploading another file (router-sample.pdf) to the same opportunity record using upload file functionality in lightning. The uploaded files in the above and current scenario are shown below.
This implementation requires two components. The server communication is modularized into an abstracted component which is then extended to the second component as needed. Continue reading →
In lightning, we have developed multiple components for different functionalities. All custom components include a lot of boilerplate code and we will have to exclude most of the redundant code by building generic function in the helper part of aura bundle. However, it wouldn’t be the perfect solution to avoid the redundancy as we will have to do the same for other components as well. For example, Communication between an apex controller and a component is written separately for each custom component, even if the components are related to each other. Are there any mechanisms available in lightning for abstracting the boilerplate into one component for others to make use of it?
From my experience, this can be solved by Inheritance as it makes the code more structured and flexible. The Salesforce Apex framework supports inheritance similar to what we see in object-oriented programming languages like Java and others. Is Aura framework built to support inheritance?
I was trying to place a quick action button to display custom lightning component to show a PDF. The quick action popup is coming with a default header and footer. The footer has only one cancel action button but, we need to have 3 action buttons, to perform savePDF, emailPDF and cancel.
To achieve this I have created a custom header, body and footer using SLDS styling. But the content is displayed on the modal popup’s body, with some padding and margin.
How to remove the extra padding and margin in the action popup from the component?
I tried multiple workarounds to achieve this.
Included the CSS style to remove the margin or padding in the .css part of the aura bundle of my component. But, it is not possible to change the parent popup’s style from the child component due to THIS keyword in CSS.
Included an external stylesheet into the component as a static resource (using ltng:require). It was working fine but the style will be applied to all the quick action popups in the application.
HTML style tag cannot be used inside a component as it throws an error on saving.
