Check Combo in Matrix

Hi,
How do I check whether a combo is selected? The combo is bind to the matrix using screen painter.
I have tried this but it is not working:
oMatrix.Columns("ColName").Cells.Item(i).Specific.Selected.Value = ""
I am using VB and 2004B. Help appreciated.

Hi,
If ((pVal.EventType = SAPbouiCOM.BoEventTypes.et_GOT_FOCUS And pVal.ItemUID = "Matrix1" And pVal.ColUID = "ColumnID" And pVal.Before_Action = False)) Then
                    oCombo = oMatrix.Columns.Item(pVal.ColUID).Cells.Item(pVal.Row).Specific
                    If oCombo.Selected Is Nothing Then
                        oCombo.Select(0, SAPbouiCOM.BoSearchKey.psk_Index)
                    Else
                        SBO_Application.MessageBox("Combo selected")
                    End If
                End If
This event gives me a selection even before losing the focus of combobox item.
Hope it may be of use to u.
Cheers

Checking status of matrix row

Greetings All,
Does anyone know how i can check if a matrix row is enabled or disabled prior to updating the field? I need to know because my add on is throwing an exception stating invalid form item if the matrix row is disabled.
Any ideas?

Hi Curtis
I'm not aware if you can make a row enabled or disabled...never seen it. I know you can make a whole matrix enabled or disabled. Also if you want an extra line in the matrix you add a extra one and that then becomes available. When you say disabled is this when you haven't said you want an extra row and it doesn't allow to add the row details?
Well, to check if a matrix is enabled you do something like
Dim item As SAPbouiCOM.Item
item = oForm.Items.Item("matrixID")
If item.Enabled = False Then item.Enabled = True
Then to see how many records are in your matrix use
oMatrix.RowCount
It will return the number of records in the matrix. But remeber if its your own matrix you should always add a line omatrix.addrow before specifying the row contents.
Hope this helps

Check box in matrix column bind correctly but doesn't appear check sign

Dear Sirs,
I have a check box in a matrix column (the matrix is placed i an extra folder in the item master data form).
The column is bound to a DBDataSource related to the user defined table @IIT_ITM1 as reported in the following code. The table field bound to the check box column is alphanumeric of size 1.
I use the following code:
                oCln = oMtx.Columns.Add("Per_coll", SAPbouiCOM.BoFormItemTypes.it_CHECK_BOX);
                oCln.DisplayDesc = true;
                oCln.Description = "For test";
                oCln.TitleObject.Caption = "For test";
                oCln.ValOn = "Y";
                oCln.ValOff = "N";
                oCln.Width = 60;
                oCln.DataBind.SetBound(true, "@IIT_ITM1", "U_IIT_PerColl");
                oCln.Editable = true;
The problem is: the binding to the database work (if I click on the check box and save the data, then the database content change accordingly) but I CANNOT LET THE USER SIGN APPEAR on the check box control!
Does anyone have the solution?
Thank you for help

Populate Combo in matrix

Hi,
     I have a Matrix.
     In Each row i want like to populate matrix with values based on the row.
     My problem is once a combo gets populated in one row, the same value
     gets populated for other rows also(inspite of changing values)
     This is my code

            Loop
     Pls help.

The design of the matrix implies that all row-comboboxes have the same data, you cannot change that.
Maybe use the double click event to popup a form and show the different possible values depending on the row

Combo box Matrix

Hi,
How can I populate a combo box in a matrix with different values?
The combobox will have a dynamic data coming from a table for each description.
Supposed, if I my matrix would look like the following.
Description                          Option(combobox)
ABC                                      Yes/No
DEF                                      Excellent/Good/Poor
GHI                                       High/Medium/Low
How would I do it?
Thanks,

Hi jaun,
you write the code in Key_Down Event Of Description field
'Assuming clCombo as Combobox column,DESCUID as Description field ColUID and it is Edit Text
If Description field is also combo box then you add this code in Combo_Select in before action false
if pVal.ColUid="DESCUID" and Pval.Row>0 then
dim objCombo as SAPbobsUICOM.ComboBox
dim i as integer
objCombo =objMatrix.Columns.Item("clCombo").Cells.Item(Pval.Row).Specific
for int=0 to objCombo.ValidValues.Count-1
objCombo.ValidValues.Remove(0)
Next
if objMatrix.Columns.Item("DESCUID").Cells.Item(Pval.Row).Specific.Value="ABC" then
objCombo.ValidValues.ADD("Y","YES")
objCombo.ValidValues.ADD("N","NO")
end if
if objMatrix.Columns.Item("DESCUID").Cells.Item(Pval.Row).Specific.Value="ABC" then

Add combo in matrix

How to add combo in system matrix ? I am adding a column in the matrix of A/R invoice.I am using the following code-

        Dim ddlAP As SAPbouiCOM.ComboBox
objForm = SBO_Application.Forms.ActiveForm
            If objForm.DataSources.UserDataSources.Count = 228 Then
                objForm.DataSources.UserDataSources.Add("ddlAP", SAPbouiCOM.BoDataType.dt_LONG_TEXT, 50)

            ddlAP = matMatrix.Columns.Item("AP").Cells.Item(0).Specific
            objForm.Refresh()
But the combo is note getting displayed.

Hi Dilip,
You cannot change (add or modify) a system matrix via SDK. If you need to add a ComboBox in a system matrix you need to create a UserField with ValidValue or connected to a User Table.

Insertar combo en matrix

Hola a todos.... el problema que tengo y espero me puedan ayudar es que tengo un matrix de sap, pero nesesito que una de las columnas de ese matrix en ves de mostrar texto me muestre un combo con informnacion de los turnos de una empresa ....alguien me puede ayudar .. este es el codigo que estoy ocupando:
   For Li_Fila = 0 To Lo_Personal.TotalFilas - 1
            Lo_Personal.Fila = Li_Fila
            Lo_UserDataSource = Mo_Forma.DataSources.UserDataSources.Item(MatrixCambiaTurnosNumero)
            Lo_UserDataSource.Value = Lo_Personal.Empleado
            Lo_UserDataSource = Mo_Forma.DataSources.UserDataSources.Item(MatrixCambiaTurnosOriginal)
            Lo_UserDataSource.Value = Lo_Personal.TurnoDescripcion
''En esta columna es en la que deseo mostrar el combo.....
            __Lo_UserDataSource = Mo_Forma.DataSources.UserDataSources.Item(MatrixCambiaTurnosCambio)__
            __Lo_UserDataSource.Value =Lo_cboTunos.Selected.Description__

Asi como lo tengo ahora me muestra la forma de combo con un valor pero al darle click no me despliega el resto de los valores....
alguien sabe como puedo solucionar esto
De antemano les agradesco ....

Jorge Luis
Sobre el punto que mencionas te puedo decir lo siguiente:
           ' Creando los UserDataSources para la columna tipo combo
           oMyForm.DataSources.UserDataSources.Add("udsColumna", SAPbouiCOM.BoDataType.dt_SHORT_TEXT)
            oMatrix = oMyForm.Items.Item(MyMatrix).Specific
            oColumns = oMatrix.Columns
             ' Asignando el UserDataSources a la columna tipo combo
             oColumns.Item("c_Columna").DataBind.SetBound(True, "", "udsColumna")
            oMatrix = oMyForm.Items.Item(MyMatrix).Specific
            oColumns = oMatrix.Columns
            ' Agregando valores al combo de la columna tipo combo
            oColumns.Item("c_Columna").ValidValues.Add("M", "Mañana")
            oColumns.Item("c_Columna").ValidValues.Add("T", "Tarde")
            oColumns.Item("c_Columna").ValidValues.Add("N", "Noche")
            oColumns.Item("c_Columna").DisplayDesc = True
           oRecordSet.DoQuery("SELECT CODE, NAME FROM [@TABLE]")
            Dim index As Integer = 1
            ' Cargando valores a las filas de la matrix
            oMatrix = oMyForm.Items.Item(MyMatrix).Specific
            While Not oRecordSet.EoF
                oMatrix.AddRow(1)
                oMatrix.GetLineData(index)
                oUserDataSource = oMyForm.DataSources.UserDataSources.Item("udsColumna")
                oUserDataSource.Value = oRecordSet.Fields.Item("CODE").Value.ToString.Trim
                oMatrix.SetLineData(index)
                index += 1
                oRecordSet.MoveNext()
            End While
Si revisas bien este codigo primero llenas la columna que es tipo combo con sus valores posibles, puedes usar un oRecordSet para llenarla si es que los datos los tienes en una tabla y pueden varias.
Al usar UserDataSource en una matrix debes usar las funciones GetLineData(index) y SetLineData(index).
Bueno espero que esto aclare tus dudas, si todo sale bien seria bueno que lo comentes.
Saludos

Matrix Empty row Binding Problem

Hi ,
i created one matrix using screen painter.. all my columns are binded
with user defined fields.(Doc Rows Table). if my total row count is 5.
and i deleted 2 rows using rightclick deleterow event. after adding if i see the same document it display the 2 empty rows and 3 rows with my details.. actually its showing that deleted row also.my UDT also having empty row details..
how to resolve this?
Regards,
Ganesh K

Hi Geetha,
i think you misunderstood my scenario. while adding no empty rows
are displayed, even if i deleted some added row details.After adding,
while retriving the same document the problem occurs.if am not clear let me know..
As you told, beforeAction = false of Add will be new form with Add mode.so not possible to check that old matrix. otherwise we can delete the empty details from database using query..in beforeaction false pval.actionsucess true part...
regards,
Ganesh k.

LoadBatchActions to Populate a Matrix

We have managed to work out some XML that can be passed to LoadBatchActions to populate a matrix in a single call (With performance being the goal), however it doesn't seem possible to populate combo box columns using this mechanism. Is there a way to populate combo box matrix cells with data using LoadBatchActions? What we have so far is something like this, but the LnType2 column is causing the operation to fail because it is a combo box column:
<?xml version="1.0" encoding="UTF-16"?>
<Application>
<forms>
    <action type="update">
      <form appformnumber="2000071350" uid="FSE_0000000">
        <items>
          <action type="update">
            <Item uid="Matrix">
              <Specific>
                <rows>
                  <action type="add">
                    <row index="0" />
                    <row index="0" />
                  </action>
                  <action type="update">
                    <row index="1">
                      <column uid="Um2" string="EA" />
                      <column uid="LnType2" string="P" />
                    </row>
                    <row index="2">
                      <column uid="Um2" string="EA" />
                      <column uid="LnType2" string="P" />
                    </row>
                </rows>
              </Specific>
            </Item>
          </action>
        </items>
      </form>
    </action>
</forms>
</Application>

Hi Benjamin,
In the Business One UI API 2004 help file you could find an issue named "Adding Forms with XML" where it is explained the file format.
Moreless, you should use the valid values property under ItemSpecific tag to set the possible options, and then add some datasources to link the controls on the matrix with the tables in the DB.

Help with sparse matrix

I need to create a sparse matrix implementation. Only allocate space for non-zero matrix elements. Implement methods for addition, subtraction, multiplication and determinant. Here is how I want to implement it:

Please help. The code runs just fine. The only thing is I need to link the nodes together (for each row) into a linked list and then put each linked list into an array. I need help with setEntry. The details of creating a node, attaching it to the list representing a row, etc. need to be in setEntry. Please help.
For the following matrix:
1 4 5
4 2 5
2 1 2
There is an array of three linked lists.
LinkedListsArray[0] = Entry(value=1, column=0)->Entry(value=4, column=1)->Entry(value=5, column=2)
LinkedListsArray[1] = Entry(value=4, column=0)->Entry(value=2, column=1)->Entry(value=5, column=2)
LinkedListsArray[2] = .....
Each entry is a node in the linked list.
The last twist is that if any values are zero, they shouldn't have nodes associated with them. Don't allocate nodes for zero valued entries.

Failed pre install check for 11i

Hi, newbie to 11i and am trying to install 11i on my 250GB external HD but failed pre-install checks in 3 areas
1) system utilities check (!)
2) operating system check (!)
3) file space check (x) talked about mount points in error message
Quite frustrating as i had installed the mks and mvs files on my c:\ as instructed. also i was`advised to certain tests thru the cmd prompt by entering these files; link, gnumake and cc. i got responses for link ad gnumake but no respnses for cc.
guys out there, any solutions please

Saw the same post at other place too..
While running rapid install did you give the mount points for Data_top ora_top and Appl_top to correct values
For system utils check for the PATH env variable is it pointing to right place.
For OS check .. I am not sure. (you should have checked the certiifcation matrix for this .. or may be some required patches are missing for this OS)
