Problem with ComboBox / Matrix
Hi all,
I have this problem... when I try to populate a column with comboxbox ...
Code:
Set co = lmatrix.Columns.Add("orgDist", it_COMBO_BOX)
co.TitleObject.Caption = "Dist"
co.Editable = True
co.Visible = True
co.DataBind.SetBound True, "@DIST", "Code"
Set DBSource = lfrm.DataSources.DBDataSources.Item("@DIST")
DBSource.Query
For x = 0 To DBSource.Size - 1
tp1 = Trim(DBSource.GetValue("Code", x))
tp2 = Trim(DBSource.GetValue(3, x))
co.ValidValues.Add tp1, tp2
DBSource.Offset = x
Next
- at the 'co.ValidValues.Add tp1,tp2' I receive this error
'Valid Value - The Value Exceed boundaries'
- tp1 max value is of 8 Char
- tp2 max value is of 50 Char
I've try to insert manually the value like validvalue.add "101","23123123....213" and it work correctly..
where is my error??
Bye!!
PS: Sorry for my english
Hi,
There's no problem with your code itself (however you don't need to set the DBDataSource offset, if you are only filling the ComboBox - GetValue picks the right data anyway...). It works fine (at least with 2004 PL23 + 2005 Build 119).
Looks like a problem with your data (or some "old" bug, but this would be the first time I heard about it...)?
...or did you solve it in the meantime?

Frank

Hi Guys,
I am facing a problem with the use of the matrix.
I am not able to select cells from the matrix with a click although I set the SelectMode = ms_Auto.
does someone know how to solve this problem ??
Thanks
BopHi Peter,
It depends on what selection style you want the grid to have. I usually set the selection mode to ms_None, this mode allows you to select the individual cells. The ms_Auto selection mode enables an entire row to be selected.

Custom DataGrid problems with Comboboxes
I am using a custom datagrid with comboboxes and
colorpickers. I found this code on the web and adapted it to work
with my code. The only problem is that if you pull down a combobox
and then click somewhere outside without selecting anything, it
seems to erase the data in the dataprovider arraycollection and so
'value' in the set data method becomes null.This is not a bug if I understand you properly. I believe most people would wish anything which is obtained via the tv to be backed up, which is why the content is transferred. If you want it to remain available on the tv you will need to sync it back to it.

Hi experts,
i am keeping a combobox renderer and editor in my JTable for 2 columns say 5th column and 7th column.
In renderer no Problem.
But while i am editing ,whenever i am choosing a perticular item from the drop down in the first row of table,it is affecting the remaining set of rows.,not all the rows also.
for example,next 5 rows are getting the same selected value.
next some 2 rows are getting affected.
the below 2 class are my renderer and editor.public class ComboBoxRenderer extends JComboBox implements TableCellRenderer {
public ComboBoxRenderer(String[] items) {
super(items);
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
if (isSelected) {
// Select the current value
setSelectedItem(value);
return this;
}My ComboBox editor is public class ComboBoxEditor extends DefaultCellEditor {
public ComboBoxEditor(String[] items) {
super(new JComboBox(items));
}so i am using this render and editor in my swing screen by the following codeString strSP[] = {"P", "O", "H", " "};
column5.setCellEditor(new ComboBoxEditor(strSP));
column5.setCellRenderer(new ComboBoxRenderer(strSP));I am sure like the problem with my renderer and editoronly,but i am helpless.
Please if someone help me to come out of this problem,it will be much helpful for me .
thanksHi,
Thanks for u'r reply
I tried in so many ways.
I tried with u'r editor,and sun forum examples also.
I brief what i want.
I am having table with 3 column.
The zeroth col, and the 2 col is a combo box.so i am rendering.
when i choose a one from zeroth col combo Box ,the 2nd col ComboBox value has to change into YES
when i choose a apart from one from zeroth col combo Box ,the 2nd col combo Box value has to change into NO.
Here my Problem is
When ever i am choosing the particular value from the 1st combo box,it is affecting the all the combobox values below(set of values,not all)..To solve that i kept the commented line in the renderer but it is creating the new problem.
I am very seriously working to solve this problem,if any one suggest to solve this,it will be very much helpful to me.

2007A - Problem with Combobox.Selected with an empty value
Hi all,
I 've tried to launch my add-on created with SBO 2005 SP1
on 2007 client.
I've a problem when I try to do
myCombobox.Selected.Value
when the valid value is empty.
Selected is null and I've an error.
So I must test each Combobox by doing this :
if( myCombobox.Selected is null)
But I've hundreds of this case in my code.
Does an another solution exists?
Thanksyou have the same problem in every business one version.
you first have to check if the property is not null/nothing
the only other way is that you use try / catch
value = oform.Items.Item("cmb1").Specific.selected.value()
Catch ex As Exception
value = ""
End Try
but the effort is the same for you -

Performance problems with combobox and datasource
We have a perfomance problem, when we are connecting a datatable object or something like this to a datasource property of a combobox. Below you find the source code. The SQL-Statement reads about 40000 rows and the result (all 40000) should be listed in the combobox. There is duration about 30 second before this process has finished. Any suggestions?
Dim ds As New DataSet
strSQL = "Select * from am.city"
conn = New Oracle.DataAccess.Client.OracleConnection(Configuration.ConfigurationSettings.AppSettings("conORA"))
comm = New Oracle.DataAccess.Client.OracleCommand(strSQL)
da = New Oracle.DataAccess.Client.OracleDataAdapter(strSQL, conn)
conn.Open()
da.Fill(ds)
conn.Close()
Dim dt As New DataTable
dt = ds.Tables(0)
ComboBox1.DataSource = dt
ComboBox1.ValueMember = dv.Table.Columns("id").ColumnName
ComboBox1.DisplayMember = dv.Table.Columns("city").ColumnNameBut how long does it take to fill the DataTable?
I can fill a 40000 row datatable in under 4 seconds.
DataBinding a combo box to that many rows is pretty expensive, and not normally recommended.
David
Dim strConnection As String = "Data Source=oracle;User ID=scott;Password=tiger;"
Dim conn As OracleConnection = New OracleConnection(strConnection)
conn.Open()
Dim cmd As New OracleCommand("select * from (select * from all_objects union all select * from all_objects) where rownum <= 40000", conn)
Dim ds As New DataSet()
Dim da As New OracleDataAdapter(cmd)
Dim begin As Date = Now
da.Fill(ds)
Console.WriteLine(ds.Tables(0).Rows.Count & " rows loaded in " & Now.Subtract(begin).TotalSeconds & " seconds")
outputs
40000 rows loaded in 3.734375 seconds -
I have a panel in table view. One of the fields, I have changed to a combo box. It works good except for one problem. When testing, I set the text in the field using the combo box. If I go directly to another record, in the same column, when i change that record, the one i had changed in the previous record changes also. It's like it has never lost focus of the previous record. I can click in another field in the previous record before going to the new record and it works OK. Any suggestions???
Thanks, WilliamLook in the API under combobox, there are 2 constructors there that may interest you--one for an array and another for a vector. Make your return object of either of those and you'll be fine.He's been told to use an array as the parameter several times, all to no avail. I'm beginning to lose hope for this one.Ok I'm sorry I've not got it yet but I just don't understand. Let me try again.
I have a method in my other class
private ArrayList< String > Quizbook= new ArrayList< String >(); // at the top of the program declaring it.
public ArrayList getwhole() // the method to return it
return Quizbook;
}So that method returns the Quizbook which is an Array? am I right so far?
Then in my other class I have
JComboBox Answer = new JComboBox(Vector (Q.getwhole));Q is an object in that previous class and '.getwhole' bieng the above method. that returns the array Quizbook. so surely I am using the array as the parameter?
And then I looked up the api and it says:
JComboBox
public JComboBox(Vector items)
Creates a JComboBox that contains the elements in the specified Vector. By default the first item in the vector and therefore the data model) becomes selected.
Parameters:
items - an array of vectors to insert into the combo box
See Also:
DefaultComboBoxModel
so if items is the parameter that you are saying should be an array then how come it isn't in the way I'm doing it the method I'm telling it to call getwhole which returns the array??
I know its probaly very tedious repeating things but It would help me alot if you could just go over it again explaining exactly where I'm going wrong. -
Problem with combobox.select method in 2007A
Hi,
When I'm trying to select the empty validvalue with a combo in SBO 2007 A, I've the error "Out of Range"
myCombo.Select( 0, BoSearchKey.psk_Index);
However I'm sure that the item 0 of my ValidValues is blank.
I tried to do the same thing by value or description and it's the same problem.
Can anyone help me ?
Thanks
(I'm using 2005 version of SAPboui/bobsCom.dll)Hi Julien,
i tried it as
oComboBox.ValidValues.Add("1", "Combo Value 1")
oComboBox.ValidValues.Add("", "") - as you wrote
oComboBox.ValidValues.Add("2", "Combo Value 2")
oComboBox.ValidValues.Add("3", "Combo Value 3")
oComboBox.Select("", SAPbouiCOM.BoSearchKey.psk_ByValue)
oComboBox.Select(1, SAPbouiCOM.BoSearchKey.psk_Index)
and both select method work. Are you sure that you have added this blank value?
Try to debug it as
Dim q As Integer
Dim s As String
For q = 0 To oComboBox.ValidValues.Count - 1
s = oComboBox.ValidValues.Item(q).Value
Next
maybe it helps you.

7rouzHi 7rouz,
Go into your pageDef, find the iterator on which your list is based, then change the "rangeSize" option to -1 (which means "get all entries", i assume it is set to 10 for the moment and so displays only 10 entries)
Hope that works,

//THIS IS ROW 166
cells[z]=split_temp2[z];
j++;
num_col=num_col+num_col;
}why are you adding num_col to itself? The number of columns is not changing, and this is causing z to go beyond what you've already set the cells array size to be. Arrays in Java will not grow or shrink after declaring them. If you want a larger array, you need to create a new array and then copy everything to the new array (System.arraycopy). -

int numCols = 5;
double [][] matrix = new double[numRows][];
for (int m = 0; m < numRows; ++m)

matrix[m][n] = (double)(m + n);
for (int m = 0; m < numRows; ++m)
for (int n = 0; n < numCols; ++n)
System.out.print(matrix[m][n] + " ");
System.out.println();
}Note the calls to "new". -
Problem with Matrix/Checkbox/Datasource
Hi, i have a problem with a Matrix.
There are 3 Columns on this Matrix, one of those is a Checkbox. I fill the Columns with data, the Checkboxes where just added (no Checkbox is selected), the user has to select the value (Checkbox)he want's to by hand.
After i filled the Matrix i can see all the data on the Form, it's OK, but then i loose all entries after SBO is doing some work. There where shown only the empty rows and the checkboxes.
I guess it has something to do with the databinding. My problem is that i don't have the Data for this form on a db-table. I fill in the matrix the result of some querys. It looks like i need at least a DB-Field for the checkboxes, otherwise there are not working (not selectable)
Somebody knows a solution how i can keep the Data in the Matrix after SBO is doing some work? What could be the reason that i loose the data after filling it in the Matrix? Is there an easy way?
Thanks AndreasAlmost every item on a form need a datasource... If the item reprecents some data in a table the databinding must be a dbds... If the data does not reflect any data in a table (Calulated value, user-decision, ect.) a userdatasource need to be created...
Add a userdatasource
oForm.DataSources.UserDataSources.Add(UID,type,length);
Databind to DBDS
col.DataBind.SetBound(true,TABLE,FIELD);
Databind to UDS
col.DataBind.SetBound(true,,UID);
