editR | A Rmarkdown editor with instant preview | Data Visualization library

Good morning everyone, I have a button component that controls whether or not the user wants to make something a favorite or not. Everything works like it should, as long as I don't log out or refresh the page.

I feel like I know the logic of how to implement this, but I can't seem to figure out how to do it.

I have the array of favorites saved in local storage, as well as in my database. How would I go about setting the state of the button to be clicked or not on initial render?

here is the code for my button.

I am trying to learn android and i don't know how to pass data from one activity to another

I'm trying to post a list of objects to a MVC controller via AJAX, but when it gets to the controller the editedPrices parameter is 0.

What am I doing wrong? Currently I'm not sure if the issue is with the data I'm sending or the controller.

Java Script:

i want to allow 0 and greator than 5 numbers in an input field.

Allowed Numbers: 0, 5, 10, 11, 12 ...

Not Allowed Numbers negative number, 1,2 3, 4

The cell in the DataGrid correctly updates if I change the value of the property in the code, but the value of the property does not change if I modify the value in the cell itself. In fact, if I modify the value in the cell, it immediately returns to the value it was set to before that.

I'm working on an app where you can set TV episode rating data, and I'm using this datagrid for that purpose. Here is the relevant XAML:

I'm building an edit button for my CRUD app. In this component, each individual 'rating' is mapped into one of these components. The component starts out be displaying the rating as stored in the DB, but users can press the edit button, and it turns into a form! (eventually, I'll get initial values to populate the form fields with the data displayed in the alternate render option).

Right now for the edit button, I have a custom submit handler receiving the submitted data from the two form fields as 'formProps'. However, before passing these off to the backend API, I ALSO need to figure out how to tie an id or something to the submit handler.

As seen in the component right below the form, this whole child component has access to the necessary passed down from the parent which can accessed as 'this.props.id'. Is there anyway to bundle 'this.props.id' with formProps before the handleSubmit takes it all to Redux Actions?

I have used ExpandebleListView in my code , Rows are dynamically generated on ADD Button click. Each New Row contain two EditText.

Now when i click on Clear Button, it clear list items, but when i click on add new item, its showing new with last inputed value inside EditText.

So, How to clear all contents and items Without changing activity on Button Click ?

Here's My code for clear Data

I have a Bootstrap modal that is triggered by a link that passes in a number of parameters which displays a select list for users to choose a rating between 1 and 5. This part is working well, but I now need to have the select menu display the value for the current rating instead of defaulting to 1 which is the first value in the list.

Here's my code:

I tried to add data to sqlite, but when I clicked Add Button error appear and my app closed. I don't understand, so many wasted hours for looking the solution by myself..

here is my java code, AddSampleActivity.java
