问题描述
我需要显示混合硬编码字符串和数据库中的数据的数据。具体来说,每个偶数列都包含非数据库的字符串值,每个奇数列都包含数据。因此,列1例如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几次):
I need to display data that will be hybrid "hard-coded" strings and data from a database. Specifically, every even-numbered column contains string values that are NOT from the database, and every odd-numbered column contains data. So column 1, for example, will contain values 1 through 12 from the database, so that the first two columns look something like this (and the same pattern repeats several times):
00:00 BoundVal1
00:15 BoundVal2
. . .
02:45 BoundVal12
这可能吗?
现在我正在使用一个TableLayoutPanel,但是它的编码有点小巧(不是Steely Dan参考)。
Right now I'm using a TableLayoutPanel for this, but the coding for that is a little pretzly (not a Steely Dan reference).
推荐答案
我终于得到了这个工作,根据Mohamed Mansour的代码
I finally got this working, based on code from Mohamed Mansour at http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/ca89a857-6e17-44a7-8cdb-90d64a0a7bbe
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)) {

}
return val;
