所以我通过一个存储过程访问一个数据库,并且能够将我想要的数据拉到一个弹出框中。现在的问题是,无论我点击哪一行,相同的数据都会不断填充我的字段。我怎么能选择一个特定的行,并从数据库中提取该特定行的数据?谢谢你的帮助
表格1
public partial class DSC_Mon : Form
{
DSCU_SvcConsumer.MTCaller Caller;
DataSet dsZA;
DataSet dsOut;
public DSC_Mon()
{
InitializeComponent();
Caller = new DSCU_SvcConsumer.MTCaller();
dsZA = new DataSet();
dsOut = new DataSet();
}
private void DSC_Mon_Load(object sender, EventArgs e)
{
timer1.Enabled = true;
}
private void LoadData()
{
if (!dsZA.Tables.Contains("Query"))
{
DataTable dtZA = dsZA.Tables.Add("Query");
dtZA.Columns.Add("str");
dtZA.Rows.Add(string.Format(@"exec MON_GetStatus"));
}
//dtZA.Rows.Add(string.Format(@"select * from am_company"));
dsOut.Clear();
dsOut.Merge(Caller.CallRequest("ZuluAction", dsZA));
if (gridEXMon.DataSource == null)
{
gridEXMon.DataSource = dsOut;
gridEXMon.DataMember = "Table";
}
//gridEXMon.RetrieveStructure();
}
private void timer1_Tick(object sender, EventArgs e)
{
timer1.Enabled = false;
LoadData();
timer1.Enabled = true;
}
private void gridEXMon_DoubleClick(object sender, EventArgs e)
{
ReportInfo report = new ReportInfo();
report.ShowDialog();
}
}
我将私有 void gridEXMon_DoubleClick 替换为:
private void gridEXMon_RowDoubleClick(object sender, Janus.Windows.GridEX.RowActionEventArgs e)
{
if (e.Row.RowIndex < 0)
return;
int rowIndex = Convert.ToInt32(e.Row.RowIndex);
ReportInfo report = new ReportInfo(rowIndex);
report.ShowDialog();
}
弹出对话框
public partial class ReportInfo : Form
{
public ReportInfo()
{
InitializeComponent();
DSCU_SvcConsumer.MTCaller caller = new DSCU_SvcConsumer.MTCaller();
DataSet dsZA = new DataSet();
DataSet dsOut = new DataSet();
if (!dsZA.Tables.Contains("Query"))
{
DataTable dtZA = dsZA.Tables.Add("Query");
dtZA.Columns.Add("str");
dtZA.Rows.Add(string.Format(@"MON_ReportInfo"));
}
dsOut.Clear();
dsOut.Merge(caller.CallRequest("ZuluAction", dsZA));
DataTable dt = dsOut.Tables["Table"];
DataRow dr = dt.Rows[0];
if (dt != null)
{
systemNameTextBox.Text = dr["System"].ToString();
contactName1TextBox.Text = dr["Manager"].ToString();
functionNameTextBox.Text = dr["Function"].ToString();
durationMSTextBox.Text = dr["Speed"].ToString();
}
}
然后我将 rowIndex 发送到弹出窗口:
DataTable dt = dsOut.Tables["Table"];
DataRow dr = dt.Rows[rowIndex];
systemNameTextBox.Text = dr["System"].ToString();
contactName1TextBox.Text = dr["Manager"].ToString();
functionNameTextBox.Text = dr["Function"].ToString();
durationMSTextBox.Text = dr["Speed"].ToString();
}
