How to make a personalized filter for DataGridPro while looping through a collection of items?

edit

To create a personalized filter for DataGridPro while looping through a collection of items, you can follow these steps:

1. Create an array or object to store all the filters you want to apply to your DataGridPro component. For example, you can create an object with keys that correspond to the fields in your DataGridPro component and values that correspond to the filter function for each field.

2. Loop through each item in your data collection.

3. For each item, you can apply the filters from step 1 to determine if the item should be displayed in the DataGridPro component.

4. To apply each filter, you can use the filterModel prop of the DataGridPro component. You can set the filter for a specific field using the columns prop, which is an array of objects that describe each column in the DataGridPro component.

5. Once you have set the filter for each field, you can use the onFilterModelChange prop to update the filter model whenever a filter is changed, so that the DataGridPro component displays only the filtered items.

Here's an example of how you can create a personalized filter for a DataGridPro component while looping through a collection of items:

const filters = {
  name: (value, item) => item.name.toLowerCase().includes(value.toLowerCase()),
  age: (value, item) => item.age >= value,
  email: (value, item) => item.email.toLowerCase().includes(value.toLowerCase())
}

const columns = [
  { field: 'name', headerName: 'Name', width: 150 },
  { field: 'age', headerName: 'Age', width: 70 },
  { field: 'email', headerName: 'Email', width: 250 },
]

const data = [
  { id: 1, name: 'John', age: 25, email: 'john@example.com' },
  { id: 2, name: 'Jane', age: 30, email: 'jane@example.com' },
  { id: 3, name: 'Bob', age: 40, email: 'bob@example.com' },
]

// Apply filters to data
const filteredData = data.filter((item) => {
  return Object.keys(filters).every((key) => {
    const filterFn = filters[key]
    const filterValue = filterModel[key]?.value

    // Apply filter for current field
    return !filterValue || filterFn(filterValue, item)
  })
})

// Render DataGridPro component with filters
<DataGridPro
  rows={filteredData}
  columns={columns}
  filterMode="server"
  filterModel={filterModel}
  onFilterModelChange={(event) => setFilterModel(event.detail)}
/>

In this example, we define an object filters that contains the different filter functions for each field in our DataGridPro component. We also define an array columns that describes each column in the DataGridPro component.

We then loop through each item in our data array and filter it using the filters from filters. We use the filterModel prop to set the filter for each field, and the onFilterModelChange prop to update the filter model whenever a filter is changed.

Finally, we render the DataGridPro component with the filtered data and the defined filters. The filterMode prop is set to 'server' to indicate that we want to apply the filters on the server side.
