我需要显示混合“硬编码”字符串和来自数据库的数据的数据。具体来说,每个偶数列都包含不是来自数据库的字符串值,每个奇数列都包含数据。因此,例如,第 1 列将包含数据库中的值 1 到 12,因此前两列看起来像这样(并且相同的模式重复多次):

00:00    BoundVal1
00:15    BoundVal2
. . .
02:45    BoundVal12

这可能吗?

现在我正在为此使用 TableLayoutPanel,但它的编码有点花哨(不是 Steely Dan 参考)。

您可以只构建一个 DataTable 对象并将其设置为 DataGridView 的 DataSource。

我终于得到了这个工作,基于来自http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/ca89a857-6e17-44a7-8cdb-90d64a0a7bbe的 Mohamed Mansour 的代码

int RowCount = 12; 
Dictionary<int, string> PlatypusPairs;

. . .

private void button3_Click(object sender, EventArgs e) {
    // Retrieve data as dictionary 
    PlatypusPairs = InterpSchedData.GetAvailableForPlatypusAndDate(oracleConnectionTestForm, 42, DateTime.Today.Date);
    int ColumnCount = 16;
    // Add the needed columns
    for (int i = 0; i < ColumnCount; i++) {
        string colName = string.Format("Column{0}", i + 1);
        dataGridView1.Columns.Add(colName, colName); 
    }

    for (int row = 0; row < RowCount; row++) {
        // Save each row as an array
        string[] currentRowContents = new string[ColumnCount];
        // Add each column to the currentColumn
        for (int col = 0; col < ColumnCount; col++) {
            currentRowContents[col] = GetValForCell(row, col);
        }
        // Add the row to the DGV
        dataGridView1.Rows.Add(currentRowContents);
    }
}

private string GetValForCell(int Row, int Col) {
    string retVal;

    if (Col % 2 == 0) {
        retVal = GetTimeStringForCell(Row, Col);
    } else {
        retVal = GetPlatypusStringForCell(Row, Col);
    }
    return retVal;
}

private string GetTimeStringForCell(int Row, int Col) {
    const int TIME_INCREMENT_STEP = 15;
    var dt = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 0, 0, 0);
    dt = dt.AddMinutes(((Col * (RowCount / 2)) + Row) * TIME_INCREMENT_STEP);
    return dt.ToString("HH:mm");
}

private string GetPlatypusStringForCell(int Row, int Col) {
    int multiplicand = Col / 2;
    string val = string.Empty;
    int ValToSearchFor = (multiplicand * RowCount) + (Row + 1);
    if (PlatypusPairs.ContainsKey(ValToSearchFor)) {
        PlatypusPairs.TryGetValue(ValToSearchFor, out val);
        if (val.Equals(0)) {
            val = string.Empty;
        }
    }
    return val;
}
