@sanketsahusoft Take a look on this, plz

[sanketsahu]

@NazarYablonskiy Do you have a use-case example for the same?

[nyablo]

@sanketsahusoft I'm sorry. I don't understand your question. What do you mean?

In my app I need to change a tab programmatically. I made a small changes to make it possible to do that.

@NazarYablonskiy How do you use this feature? I am asking for an example so that we can document this.

@sanketsahusoft

import React, {Component} from 'react';
import {Tabs, Text, View} from 'native-base';

export default class MyComponentWithTabs extends Component {

  someEventHnadler() {
    this._tabs.goToPage(0);
  }

  ...

  render() {
    ...
    return (
      ...
      <Tabs ref={(c) => {this._tabs = c;}}>
        <View tabLabel="Tab 1">
          <Text>Tab 1</Text>
        </View>
        <View tabLabel="Tab 2">
          <Text>Tab 2</Text>
        </View>
      </Tabs>
      ...
    );
  }
}

Thanks for this, but i have a rather different case though, the above code works when the button link to navigate is in the same component as the tab, but i have a button link inside another component called from the main tab component. Please how do i bind this to work. thanks
