c#devexpress gridview选择行计数错误 我想从另一个表格(gridcontrol)获取行,我尝试了form.gridview.selected.row.count但它不起作用。得到这个数字我能写些什么?从其他形式的钱,我想打印标签来收集这个表格。 ""
gridView1.Columns["money"].SummaryItem.SummaryType = DevExpress.Data.SummaryItemType.Sum;
gridView1.Columns["money"].SummaryItem.DisplayFormat = "Toplam:{0:n2}";
gridView1.OptionsView.ShowFooter = true;
"" 我尝试这个代码工作但在gridview但我想在标签中写其他形式。

form1有gridView1。
form2有label2。 label2显示来自gridView1的总和。
form1必须将form2作为其字段或属性。
form2必须有方法public void SetSum(money sum)
才能为label2设置总和。
每个计数总和(例如通过点击按钮)调用form2.SetSum(sum)
MainForm.cs - 主机form1和form2
public partial class MainForm : Form
{
private Form1 _form1;
private Form2 _form2;
public MainForm()
{
InitializeComponent();
_form2 = new Form2();
_form1 = new Form1(_form2);
}
private void btnForm1_Click(object sender, EventArgs e)
{
_form1.Show(this);
}
private void btnForm2_Click(object sender, EventArgs e)
{
_form2.Show(this);
}
}
Form1.cs的
public partial class Form1 : Form
{
private Form2 _receivedForm;
public Form1()
{
InitializeComponent();
}
public Form1(Form2 receivedForm) : this()
{
_receivedForm = receivedForm;
}
private void btnSend_Click(object sender, EventArgs e)
{
_receivedForm.SetSum(txtSum.Text);
}
}
Form2.cs:
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
public void SetSum(string sum)
{
lblSum.Text = sum;
}
}
希望这有帮助。 :d

ı确实使用此代码现在正在工作。谢谢你的回答
DataBaseDataContext db = new DataBaseDataContext();
var sum = (from ord in db.safes select ord.money).Sum();
lbl_safein.Text = sum.ToString();
