Double-click DataGridView row?
提问by Alex
I am using vb.net and DataGridView on a winform.
我在 winform 上使用 vb.net 和 DataGridView。
When a user double-clicks on a row I want to do something with this row. But how can I know whether user clicked on a row or just anywhere in the grid? If I use DataGridView.CurrentRowthen if a row is selected and user clicked anywhere on the grid the current row will show the selected and not where the user clicked (which in this case would be not on a row and I would want to ignore it).
当用户双击一行时，我想对这一行做一些事情。但是我怎么知道用户是点击了一行还是只是在网格中的任何地方？如果我使用，DataGridView.CurrentRow那么如果选择了一行并且用户单击了网格上的任意位置，当前行将显示选定的而不是用户单击的位置（在这种情况下不会在一行上，我想忽略它）。

Try the CellMouseDoubleClickevent...
试试CellMouseDoubleClick活动...
Private Sub DataGridView1_CellMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.CellMouseDoubleClick
If e.RowIndex >= 0 AndAlso e.ColumnIndex >= 0 Then
Dim selectedRow = DataGridView1.Rows(e.RowIndex)
End If
End Sub
This will only fire if the user is actually over a cell in the grid. The Ifcheck filters out double clicks on the row selectors and headers.
这只会在用户实际位于网格中的单元格上方时触发。该If检查筛选出的行选择和头双击。

Use Datagridview DoubleClick Evenet and then Datagrdiview1.selectedrows[0].cell["CellName"] to get value and process.
使用 Datagridview DoubleClick Eventet 和 Datagrdiview1.selectedrows[0].cell["CellName"] 获取值并进行处理。
Below example shows clients record upon double click on selected row.
下面的示例显示了双击选定行时的客户记录。
private void dgvClientsUsage_DoubleClick(object sender, EventArgs e) {
私有无效 dgvClientsUsage_DoubleClick（对象发送者，EventArgs e）{
if (dgvClientsUsage.SelectedRows.Count < 1)
{
MessageBox.Show("Please select a client");
return;
}
else
{
string clientName = dgvClientsUsage.SelectedRows[0].Cells["ClientName"].Value.ToString();
// show selected client Details
ClientDetails clients = new ClientDetails(clientName);
clients.ShowDialog();
}
}

Use DataGridView.HitTestin the double-click handler to find out where the click happened.
在双击处理程序中使用DataGridView.HitTest找出单击发生的位置。

You can try this:
你可以试试这个：
Private Sub grdview_CellDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles grdview.CellDoubleClick
For index As Integer = 0 To grdview.Rows.Count - 1
If e.RowIndex = index AndAlso e.ColumnIndex = 1 AndAlso grdview.Rows(index).Cells(1).Value = "" Then
MsgBox("Double Click Message")
End If
Next
End Sub

I would use the DoubleClickevent of the DataGridView. This will at least only fire when the user double clicks in the data grid - you can use the MousePosition to determine what row (if any) the user double clicked on.
我会使用DataGridView的DoubleClick事件。这至少只会在用户双击数据网格时触发 - 您可以使用 MousePosition 来确定用户双击了哪一行（如果有）。

You could try something like this.
你可以尝试这样的事情。
Private Sub DataGridView1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGridView1.DoubleClick
For index As Integer = 0 To DataGridView1.Rows.Count
If DataGridView1.Rows(index).Selected = True Then
'it is selected
Else
'is is not selected
End If
Next
End Sub
Keep in mind i could not test this because i diddent have any data to populate my DataGridView.
请记住，我无法对此进行测试，因为我没有任何数据来填充我的 DataGridView。
