Angular Material. to highlight a table row on mouse over

Update for Newer Material Version (md --> mat):

html:

<!-- Add the highlight class in row definiton of md-table -->
<!-- Add click event to pass the selected row index -->

<mat-row *cdkRowDef="let row; columns: displayedColumns;" 
         [ngClass]="{'highlight': selectedRowIndex == row.id}"
         (click)="highlight(row)">
</mat-row>

Original Answer:

You can do it by using ngClass and a flag like selectedRowIndex. Whenever clicked row index is equal to selectedRowIndex, the class will be applied.

Plunker demo

html:

<!-- Add the highlight class in row definiton of md-table -->
<!-- Add click event to pass the selected row index -->

<md-row *cdkRowDef="let row; columns: displayedColumns;" 
         [ngClass]="{'highlight': selectedRowIndex == row.id}"
         (click)="highlight(row)">
</md-row>

css:

.highlight{
  background: #42A948; /* green */
}

ts:

selectedRowIndex = -1;

highlight(row){
    this.selectedRowIndex = row.id;
}

mdDatepicker provides method open() in order to open it manually doe developers. You can invoke it at md-input's focus event. See docs(Method of MatDatepicker).

<md-input-container>
  <input mdInput [mdDatepicker]="picker" (focus)="picker.open()" placeholder="Choose a date">
  <button mdSuffix [mdDatepickerToggle]="picker"></button>
</md-input-container>
<md-datepicker #picker></md-datepicker>
