There is a way but you have to careful about selection of cells . If you have to do only row operations then it is ok with this. I recommend don't do this instead that put button in gridview for each row and perform operation
<pre><code> Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
 Try

 If DataGridView1.SelectedCells.Count &gt; 0 Then

'Here you can change Datagridview row selection property and get selectedrows instead of selected cells
 Dim i_rowindex As Integer = DataGridView1.SelectedCells(0).RowIndex

 Dim i_colIndex As Integer = DataGridView1.SelectedCells(0).ColumnIndex


 DataGridView1_CellMouseClick(sender, New DataGridViewCellMouseEventArgs(i_colIndex, i_rowindex, 0, 0, New MouseEventArgs(MouseButtons.Left, 1, 0, 0, 0)))
End
 Catch ex As Exception
 MessageBox.Show(ex.Message)
 End Try
 End Sub
</code></pre>

blocks|key|1100884|text|我可能遗漏了什么，但是…我不明白你为什么要强迫用户“点击”一个按钮来设置文本框。如果连接网格“SelectionChanged”事件并更新该事件中的文本框，则用户不必单击按钮或单元格。如果用户使用箭头键，输入键，Tab键，甚至“单击”单元格，文本框将自动更改，用户不必单击按钮。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1100885|Private+Sub+DataGridView1_SelectionChanged(sender+As+Object,+e+As+EventArgs)+Handles+DataGridView1.SelectionChanged
++If+(DataGridView1.CurrentRow+IsNot+Nothing)+Then
++++TextBox1.Text+=+DataGridView1.CurrentRow.Cells(0).Value.ToString()
++++TextBox2.Text+=+DataGridView1.CurrentRow.Cells(1).Value.ToString
++End+If
End+Sub|code-block|syntax|javascript|1100886|或者..。最好还是..。如果网格使用数据源，则只需将文本框“绑定”到该“相同”数据源。您将不必连接任何网格事件。|1100887|TextBox1.DataBindings.Add(New+Binding("Text",+datasource,+"datasourceColumnName1"))
TextBox2.DataBindings.Add(New+Binding("Text",+datasource,+"datasourceColumnName2"))|1100888|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

I may be missing something, however… I do not understand why you would want to force the user to “click” a button to set the text boxes. If you wire up the grids “SelectionChanged” event and update the text boxes in that event, then the user neither has to click on a button or a cell. If the user uses the Arrow keys, Enter key, Tab key or even “clicks” a cell, the text boxes will change automatically without the user having to click a button.
<pre><code>Private Sub DataGridView1_SelectionChanged(sender As Object, e As EventArgs) Handles DataGridView1.SelectionChanged
 If (DataGridView1.CurrentRow IsNot Nothing) Then
 TextBox1.Text = DataGridView1.CurrentRow.Cells(0).Value.ToString()
 TextBox2.Text = DataGridView1.CurrentRow.Cells(1).Value.ToString
 End If
End Sub
</code></pre>
Or... better yet... if the grid uses a data source, then &quot;Binding&quot; the text boxes to that &quot;same&quot; data source is all that is needed. You will not have to wire up any grid events.
<pre><code>TextBox1.DataBindings.Add(New Binding(&quot;Text&quot;, datasource, &quot;datasourceColumnName1&quot;))
TextBox2.DataBindings.Add(New Binding(&quot;Text&quot;, datasource, &quot;datasourceColumnName2&quot;))
</code></pre>

blocks|key|1100909|text|正如我可能已经提到的一两次，不要直接调用事件处理程序。将公共代码放入自己的方法中，然后酌情从每个事件处理程序中调用该方法。在这种情况下：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1100910|Private+Sub+Button1_Click(sender+As+Object,+e+As+EventArgs)+Handles+Button1.Click
++++GetRowValues(DataGridView1.CurrentRow)

Private+Sub+DataGridView1_CellMouseClick(sender+As+Object,+e+As+DataGridViewCellMouseEventArgs)+Handles+DataGridView1.CellMouseClick
++++If+e.Button+=+MouseButtons.Left+AndAlso+e.RowIndex+>=+0+Then
++++++++GetRowValues(DataGridView1.Rows(e.RowIndex))
++++End+If
End+Sub

Private+Sub+GetRowValues(row+As+DataGridViewRow)
++++TextBox1.Text+=+row.Cells(0).Value.ToString()
++++TextBox2.Text+=+row.Cells(1).Value.ToString()
End+Sub|code-block|syntax|javascript|1100911|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

As I may have mentioned once or twice, don't call event handlers directly. Put the common code in it's own method and then call that method from each event handler as appropriate. In this case:
<pre class="lang-vb prettyprint-override"><code>Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
 GetRowValues(DataGridView1.CurrentRow)
End Sub

Private Sub DataGridView1_CellMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles DataGridView1.CellMouseClick
 If e.Button = MouseButtons.Left AndAlso e.RowIndex &gt;= 0 Then
 GetRowValues(DataGridView1.Rows(e.RowIndex))
 End If
End Sub

Private Sub GetRowValues(row As DataGridViewRow)
 TextBox1.Text = row.Cells(0).Value.ToString()
 TextBox2.Text = row.Cells(1).Value.ToString()
End Sub
</code></pre>

I'm trying to trigger this command when the button is clicked
<pre><code> Private Sub ClickDataGridview(sender As Object, e As DataGridViewCellMouseEventArgs)
 If e.RowIndex &gt;= 0 Then
 Dim row As DataGridViewRow = DataGridView1.Rows(e.RowIndex)
 TextBox1.Text = row.Cells(0).Value.ToString
 TextBox2.Text = row.Cells(1).Value.ToString

 End If
End Sub
 Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
 ClickDataGridview()
 End Sub
</code></pre>
but sadly I received two error
<ol>
<li>Argument not specified for parameter 'sender' of 'Private Sub ClickDataGridview(sender As Object, e As DataGridViewCellMouseEventArgs)'.</li>
<li>Argument not specified for parameter 'e' of 'Private Sub ClickDataGridview(sender As Object, e As DataGridViewCellMouseEventArgs)'</li>
</ol>
Should I make it an if statement to work? or should I try something else to trigger this event
