向未绑定的datagridview添加新行
向未绑定的datagridview添加新行
提问于 2019-05-23 22:54:23
我有一个未绑定的datagridview。由于我对网格中的数据所做的各种事情，我不想绑定它。这些列是在datagridview的设置(编辑列)中预定义的。我想创建一个新行，然后用数据填充网格行。我正在尝试使用.Add.Rows方法，但失败的原因是
{“索引超出范围。必须是非负数并且小于集合的大小。”& vbCrLf &“参数名称:索引”}
下面的SQL检索数据：
USE CCAP
declare @ScheduleName as varchar(30) = 'Walk-In Center April Wk 1 2019'
Select ShiftName, ScheduleStart, ScheduleEnd, Position, ADP_ID1,
Name1,ADP_ID2, Name2, ADP_ID3, Name3, ADP_ID4, Name4, ADP_ID5,
Name5, ADP_ID6, Name6, ADP_ID7, Name7
from FormattedSchedules
where ScheduleName = @ScheduleName;并且行数大于0，所以它得到的是结果。我不明白什么索引超出范围，或者为什么集合是0代码如下：
尝试过.Rows.Add(1)、.Rows.Add()和.Rows.Add("")
Dim FSchedCmd As SqlCommand
Dim FSchedSQL As String
Dim FSchedConn As New SqlConnection()
Dim FSchedadapter As New SqlDataAdapter()
Dim i As Integer = 0
Dim rowIndex As Integer
Dim row As DataGridViewRow
AddedNewRow = 1
Dim dsFSched As New DataSet()
FSchedSQL = "Select ShiftName, ScheduleStart, ScheduleEnd, Position, ADP_ID1, Name1, ADP_ID2, Name2, ADP_ID3, Name3, ADP_ID4, Name4, ADP_ID5, Name5, ADP_ID6, Name6, ADP_ID7, Name7 from FormattedSchedules where ScheduleName = @ScheduleName;"

GlobalVariables.strConnection = "CCAPProdConnectionString"
Else
GlobalVariables.strConnection = "CCAPTestConnectionString"

FSchedConn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings(GlobalVariables.strConnection).ConnectionString
FSchedConn.Open()
FSchedCmd = New SqlCommand(FSchedSQL, FSchedConn)
FSchedCmd.Parameters.Add("@ScheduleName", SqlDbType.VarChar).Value = cboCreateScheduleName.Text
FSchedadapter.SelectCommand = FSchedCmd
FSchedadapter.Fill(dsFSched)
FSchedadapter.Dispose()
FSchedCmd.Dispose()
FSchedConn.Close()
