我有一个由4个数据表组成的数据集,并希望将它绑定到我的数据网格,但是当我查看数据网格时它是空的。 所以我所做的是:
DataSet dtsResults = myPcd.GetDimensionsDataSet();
dtgResults.DataContext = dtsResults.Tables;
--- --- ADD 以下是我如何形成数据集:
obcPcdlrnDimensionCommands.Clear();
int maxNumCommands = (pcdPartProgram.Commands.Count < MAX_NUM_COMMANDS) ? pcdPartProgram.Commands.Count : MAX_NUM_COMMANDS;
PCDLRN.Commands pcdCommands = pcdPartProgram.Commands;
//2. ciclo su tutti i comandi
int numTables = dtsDimensions.Tables.Count + 1;
dtsDimensions.Tables.Add("DATA_TABLE_" + numTables);
dtsDimensions.Tables[0].Columns.Add();
dtsDimensions.Tables[0].Columns.Add();
dtsDimensions.Tables[0].Columns.Add();
dtsDimensions.Tables[0].Columns.Add();
String CurName = string.Empty;
for (int iCommand = 1; iCommand < maxNumCommands; iCommand++)
{
PCDLRN.Command pcdCommand = pcdCommands.Item(iCommand);
if (pcdCommand.IsDimension && pcdCommand.Marked)
{
if (pcdCommand.Type == PCDLRN.OBTYPE.DIMENSION_START_LOCATION || pcdCommand.Type == PCDLRN.OBTYPE.DIMENSION_TRUE_START_POSITION)
{
CurName = pcdCommand.ID;
}
else
{
if (pcdCommand.ID != string.Empty)
CurName = pcdCommand.ID;
double approxMeasured = Math.Round(pcdCommand.DimensionCommand.Measured, 9);
dtsDimensions.Tables[0].Rows.Add(CurName, delenda_PART_NAME, pcdCommand.DimensionCommand.AxisLetter, approxMeasured);
}
}

WPF中的DataGrid只显示一个表,并告诉她绑定到多个表的DataSet,因为有两个选项:
1-将一个表绑定到ItemsSource,如下所示:
yourDatagrid.ItemsSource = yourDataSet.Tables[0]; \\or yourDataSet.Tables["TableName"]
2-绑定所有dataSet,然后告诉datagrid绑定你的特定表,如下所示:
<DataGrid ItemsSource="{Binding TableName}"/>
