Scroll to first selected row in v-data-table

Question

I have a v-data-table that I highlight a selected row by adding a selectedRow class to the table row. After an update in another component the v-data-table is refreshed. I want it to automatically scroll back to the selected row. I'm getting an error that the element cannot be found. It seems to not be finding the CSS selector I am trying to pass as the target.

  mounted: function () {
    eventBus.$on("refreshVendors", () => {
      this.getVendors();
      // add scrollTo first selected vendor
      this.$vuetify.goTo(".selectedRow");
    });

    this.clearSelectedVendors();
    this.getVendors();
  },

I've tried using next tick but same error occurs.

Answer 1

For current version=v2.3.6 now, The CSS class for selected row is v-data-table__selected, so changes that line to this.$nextTick(() => this.$vuetify.goTo('.v-data-table__selected')).

Below is one demo based on the snippet in official site:

PS: hit 'Goto' button at the end of the fiddle then you will see the effect.

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  methods: {
    gotoSelectedRow: function () {
      this.desserts[1].selected = false
      this.desserts[0].selected = true
      this.$nextTick(() => this.$vuetify.goTo('.selectedRow'))
    }
  },
  data () {
    return {
      headers: [
        {
          text: 'Dessert (100g serving)',
          align: 'start',
          sortable: false,
          value: 'name',
        },
        { text: 'Calories', value: 'calories' },
        { text: 'Fat (g)', value: 'fat' },
