In your managelabels_productlabel_form.xml file

Check and update field

<field name="your_field_id">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="disabled" xsi:type="boolean">true</item>
            <item name="class" xsi:type="string">{Vendorname}\{Modulename}\Ui\Component\Form\Element\Input</item>
            <item name="dataType" xsi:type="string">text</item>
            <item name="label" translate="true" xsi:type="string">Name label</item>
            <item name="formElement" xsi:type="string">input</item>
            <item name="source" xsi:type="string">[source_here]</item>
            <item name="required" xsi:type="boolean">true</item>
            <item name="dataScope" xsi:type="string">your_field_id</item>
        </item>
    </argument>
</field>

There are two way to get data value in field 

1. Using UI component

You can get data from custom ui component file

Create file In {Vendorname}\{Modulename}\Ui\Component\Form\Element\DataProvider.php

<?php

namespace {Vendorname}\{Modulename}\Ui\Component\Form\Element;

class DataProvider extends \Magento\Ui\Component\Form\Element\Input
{
  /**
     * Prepare component configuration
     *
     * @return void
     */
    public function prepare()
    {
      parent::prepare();

      $customValue = {Get Custom value};

      $config = $this->getData('config');

      if(isset($config['dataScope']) && $config['dataScope']=='your_field_id'){
        $config['default']= $customValue;
        $this->setData('config', (array)$config);
      }
    }
}

2. Get collection data from model

{Vendorname}\{Modulename}\Model\Classname using toOptionArray() method.

In Classname.php file,

<?php

namespace {Vendorname}\{Modulename}\Model\Path;

class Classname extends \Magento\Ui\DataProvider\AbstractDataProvider
{

    public function __construct(        
        \Magento\Framework\App\RequestInterface $request        
    ) {
        $this->_request = $request;
    }

    public function getData()
    {
        if (isset($this->loadedData)) {
            return $this->loadedData;
        }
        
        $itemId = $this->_request->getParam('page_id');

        if ( !empty($itemId) ) {
        $items = $this->collection->getItems();
        foreach ($items as $item) {
            $this->loadedData[$item->getId()] = $item->getData();
        }

        $data = $this->dataPersistor->get('form_item');

        if (!empty($data)) {
           //Do something
           $this->loadedData[$item->getId()] = $item->getData();
        } 
        return $this->loadedData;
    }
}

Hello @Patel_Chirag ,

Make sure you have followed this kind of code to create a new grid in admin if not then check what is missing in your code.

Thanks

How does this answer the question? What should [source] be set to and why? You've done nothing in your dataprovider that's different to what the OP did, just a little differently.

I know its been late now but might someone get help from this as i was stuck with this and found solution after 2 hours. So i am posting it here.

This might be happen when you change layout from one column to 2-column left for admin form and using tab for form.

in this case we have to change DataProvider class to meet the expectation for filling form.

Here is the change 

foreach ($items as $page) {
$formData['general'] = $page->getData(); /* general parameter is from fieldset name. */
            $this->loadedData[$page->getId()] = $formData;
            $ruleId = $page->getId();
        }

<fieldset name="general"> /* general parameter is from fieldset name. */
