I have a combobox on a datagridview. I am able to populate the values of the combobox, but what I am failing to do is to populate the data base value into the combobox "text" when the datagridview is loading.
I hope this makes sense. Basically I just want the data returned to reflect in the combobox Display.
Your assistance will be highly appreciated.
Dim cbo As DataGridViewComboBoxColumn
If GlobalVariables.UsrSite = 0 Then
SQL.ReadQuery("Select LogsReason as [Logs Update], IncNo as [Number], SiteName As [Site Name], FleetNo As [Fleet No], FleetType As [Fleet Type], Location,
SMR as [Hours], TimeDown As [Down Time], EstTimeUp as [Est Repair], DateDiff(d, TimeDown, GetDate()) as [Days Down]
from UDOData where status = 'Down' order by [Days Down] Desc")
Else
SQL.ReadQuery("Select LogsReason as [Logs Update], IncNo as [Number], SiteName As [Site Name], FleetNo As [Fleet No], FleetType As [Fleet Type], Location,
SMR as [Hours], TimeDown As [Down Time], EstTimeUp as [Est Repair], DateDiff(d, TimeDown, GetDate()) as [Days Down] from UDOData
Where SiteID = " & GlobalVariables.UsrSite & " and Status = 'Down' order by [Days Down] Desc")
End If
dgvUDO.DataSource = SQL.SQLDS.Tables(0)
cbo.DataSource = SQL.SQLDS.Tables(0)
cbo.DisplayMember = "Logs Update"
cbo.ValueMember = "Logs Update"
cbo.DataPropertyName = "Logs Update"
I get exception error saying "logs Update" does not exist, but it loads in the datagridview.
I ended up doing this, which worked for me.
Dim cbo As DataGridViewComboBoxColumn
cbo = dgvUDO.Columns("cboLogsUDO")
Dim AltDb As New DataTable
SQL.ReadQuery("Select Descrip from dbo.UDOLogs")
AltDb = SQL.SQLDS.Tables(0)
'LOAD DATA GRID VIEW DATA
If GlobalVariables.UsrSite = 0 Then
SQL.ReadQuery("Select ID, LogsReason as [Logs Update], IncNo as [Number], SiteName As [Site Name], FleetNo As [Fleet No], FleetType As [Fleet Type], Location,
SMR as [Hours], TimeDown As [Down Time], EstTimeUp as [Est Repair], DateDiff(d, TimeDown, GetDate()) as [Days Down]
from UDOData where status = 'Down' order by [Days Down] Desc")
Else
SQL.ReadQuery("Select ID, LogsReason as [Logs Update], IncNo as [Number], SiteName As [Site Name], FleetNo As [Fleet No], FleetType As [Fleet Type], Location,
SMR as [Hours], TimeDown As [Down Time], EstTimeUp as [Est Repair], DateDiff(d, TimeDown, GetDate()) as [Days Down] from UDOData
Where SiteID = " & GlobalVariables.UsrSite & " and Status = 'Down' order by [Days Down] Desc")
End If
'SET DATA GRIDVIEW DATA SOURCE
dt = SQL.SQLDS.Tables(0)
dgvUDO.DataSource = dt
dgvUDO.Rows(0).Selected = True
'LOAD UPDATE COMMAND FOR DATA GRIDVIEW CHANGES
SQL.SQLDA.UpdateCommand = New SqlClient.SqlCommandBuilder(SQL.SQLDA).GetUpdateCommand
'HIDE UNWANTED COLUMNS
dgvUDO.Columns("Logs Update").Visible = False
dgvUDO.Columns("ID").Visible = False
'SET COMBOBOX ATTRIBUTES
cbo.DataSource = AltDb
cbo.DisplayMember = "Descrip"
cbo.ValueMember = "Descrip"
cbo.DataPropertyName = "Logs Update"
This gives me the ability to call the value in the returned db for the datagridview as the combobox "text" value, but show the drop down items as the items in another table.
