設定した ValueMember 値を取得しようとして問題が発生しています。コンボボックスを使用して Windows フォーム レポートを選択しようとしています。名前は取得できますが、RptValue は取得できません。これが私のコードです：
private class Data
{
public string Name { get; set; }
public string RptValue { get; set; }
}
private void BaseForm_Load(object sender, EventArgs e)
{
this.rvDoctorReportViewer.RefreshReport();
comboBox1.Items.Add(new Data { Name="Select", RptValue="Select"});
comboBox1.Items.Add(new Data { Name = "All Food Values", RptValue = "AllFoodValues.rdlc" });
comboBox1.Items.Add(new Data { Name = "All Readings", RptValue = "AllReadings.rdlc" });
comboBox1.Items.Add(new Data { Name = "Avg Food Values by Date", RptValue = "AvgFoodValuesByDate.rdlc" });
comboBox1.Items.Add(new Data { Name = "Avg Food Values by Meal", RptValue = "AvgFoodValuesByMeal.rdlc" });
comboBox1.Items.Add(new Data { Name = "Avg Readings by Date", RptValue = "AvgReadingsByDate.rdlc" });
comboBox1.Items.Add(new Data { Name = "Avg Readings by Time", RptValue = "AvgReadingsByTime.rdlc" });
comboBox1.Items.Add(new Data { Name = "Avg Readings by Event", RptValue = "AvgReadingsByEvent.rdlc" });
comboBox1.Items.Add(new Data { Name = "Blood Pressure Chart", RptValue = "BPChart.rdlc" });
comboBox1.Items.Add(new Data { Name = "Blood Pressure Report", RptValue = "BPReport.rdlc" });
comboBox1.Items.Add(new Data { Name = "Detail Food Values by Meal", RptValue = "DetailFoodValuesByMeal.rdlc" });
comboBox1.Items.Add(new Data { Name = "Doctor Detail Report", RptValue = "DoctorDetailReport.rdlc" });
comboBox1.Items.Add(new Data { Name = "Food Chart", RptValue = "FoodChart.rdlc" });
comboBox1.Items.Add(new Data { Name = "Pumper Detail Report", RptValue = "PumperDetailReport.rdlc" });
comboBox1.Items.Add(new Data { Name = "Reading Charts", RptValue = "ReadingCharts.rdlc" });
comboBox1.Items.Add(new Data { Name = "Total Daily Food Intake", RptValue = "TotalIntakeDailyFood.rdlc" });
comboBox1.DisplayMember = "Name"; // This works fine
comboBox1.ValueMember = "RptValue"; // This is the problem. It renders as RptValue instead of the value
comboBox1.SelectedIndex = 0;
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
if (comboBox1.SelectedIndex > 0)
{
string strReport;
strReport = "ReportViewer." + comboBox1.ValueMember.ToString();
rvDoctorReportViewer.Reset();
rvDoctorReportViewer.LocalReport.ReportEmbeddedResource = strReport;
this.rvDoctorReportViewer.RefreshReport();
}
}
