How to make columns in a table dynamic

Hi,
I want to make the columns of a table dynamic.
At design time I dont know how many columns will be required.
Rows are made dynamic by using the bean concept.
Please help me in this reference(columns).
Thanks
Pooja

Hi, i don't know how you create the rows dynamically but
have you tried to use a forEach?
<af:table ...>
<af:forEach items="..." var="...">
<af:column headerText="...">
<af:outputText value="..."/>
</af:column>
</af:forEach>
</af:table>
here there is an example of a dynamic panelList:
<af:panelList rows="3" maxColumns="6">
<af:forEach items="#{bindings.ContratosView1.rangeSet}" var="li">
<af:commandLink text="#{li.Codigo}" action="Edit"/>
</af:forEach>
</af:panelList>

doc.SetPageSize(new iTextSharp.text.Rectangle(iTextSharp.text.PageSize.LETTER.Width, iTextSharp.text.PageSize.LETTER.Height));

else if (MessageBox.Show("Do you want to save changes to AssignedDialyzer.pdf before closing?", "DRRS", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Exclamation) == DialogResult.No)
this.Close();
The above code executes well with no problem at all!
As you can see the file to which i create and save and open my pdf report is
AssignedDialyzer.pdf.
The column headers of table in pdf report from c# windows forms using iTextSharp are
"Reprocessing Date","Patient Name","Dialyzer(Manufacturer,Size)","No.of Reuse","Verification" and
"DialyzerID".
However the problem i am facing is after execution and opening of document is my
column headers in table in pdf report from
c# and datas in it all appear in bold.
I have browsed through net regarding to solve this problem but with no success.
What i want is my pdf report from c# should be similar to following format which i was able to accomplish in vb6,adodb with MS access using iTextSharp.:
Given below is report which i have achieved from vb6,adodb with MS access using iTextSharp
I know that there has to be another way to solve my problem.I have browsed many articles in net regarding exporting sql datas to above format but with no success!
Is there is any another way to solve to my problem on exporting sql datas from c# windows forms using iTextSharp to above format given in the picture/image above?!
If so Then Can anyone tell me what modifications must i do in my c# code given above so that my pdf report from c# windows forms using iTextSharp will look similar to image/picture(pdf report) which i was able to accomplish from
vb6,adodb with ms access using iTextSharp?
I have approached Sound Forge.Net for help but with no success.
I hope anyone/someone truly understands what i am trying to ask!
I know i have to do lot of modifications in my c# code to achieve this level of perfection but i dont know how to do it.
Can anyone help me please! Any help/guidance in solving this problem would be greatly appreciated.
I hope i get a reply in terms of solving this problem.

How to add columns for existing table dynamically?

Hi,
I created table structure only. I want to add columns for this existing table. Columns are not fixed, according to the user choice i need to write code.
Plz give me reply asap.
Thanks
Shirisha

Hi Shirisha,
I think the following code snippet will help you.
int l_no_cols = 0;
//Get the number of columns in this variable, something like the following
//l_no_cols = wdContext().currentContextElement().get<Context_attribute_name>;
IWDTable l_tab;
IWDTransparentContainer l_tbl_cont = (IWDTransparentContainer)view.getElement("TableDataCont");//ID of Container
l_tab = (IWDTable)view.getElement("TableData");//ID of Table
l_tab.setVisible(WDVisibility.VISIBLE);
l_tab.bindDataSource(wdContext.nodeTable_Data().getNodeInfo());
for(int a = 1; a <=l_no_cols; a++)
//Creating the column
IWDTableColumn l_tab_col = (IWDTableColumn)view.createElement(IWDTableColumn.class,"COL"+a);
//Creating Caption for Column Header
IWDCaption l_tab_cap = (IWDCaption)view.createElement(IWDCaption.class,"Caption"+a);
l_tab_cap.setText("Col"+i);
l_tab_col.setHeader(l_tab_cap);
//Creating Table Cell Editor for column
IWDInputField l_tab_cell = (IWDInputField)view.createElement(IWDInputField.class,"CellEditor"+a);
//creating context node attribute for the column dynamically
wdContext.nodeTable_Data().getNodeInfo().addAttribute("Col"+i,"com.sap.dictionary.String");
l_tab_cell.bindValue(wdContext.nodeTable_Data().getNodeInfo().getAttribute("Col"+i));
l_tab_col.setTableCellEditor(l_tab_cell);
l_tab.addColumn(l_tab_col);
l_tbl_cont.addChild(l_tab);

regards!
when I try to make the range I have error.
Syntax error [nQSError: 26012] . (HY000)
SQL Issued: SELECT CASE WHEN "CUBO_DEEE_TAB"."CANTIDAD" BETWEEN 1 AND 9 THEN 1 a 9 ELSE "CUBO_DEEE_TAB"."CANTIDAD" END FROM "DM_DEEE"

You cannot add columns dynamically. But you can define a maximum number of numbers and then hide unused columns in your form useing SET_ITEM_PROPERTY(..,VISIBLE, PROPERTY_FALSE);

How to make columns in the select list dynamic

Hi
I need to make columns in the select query dynamic.I have three tables.Table 1 contains master information lets say name of group(A group consists of members of various skill sets) and its period(A group is of specific period lets say for 18 months).Table 2 contains different skill sets corresponding to a group i.e there is one to many relationship between table 1 and table 2.Table 3 contains months information of skill sets.For example if skill set 1 is required for 5 months then there will be 5 rows(for each month) in table 3 corresponding to a skill set i.e there is again one to many relationship between table 2 and table 3.Tabale 3 will also contain man month value for perticular month.I need to show all the periods of a group and its sum of man month value for all skill sets.
If group1 is of 6 months (starts nov2006 and ends Apr2007) and has 5 skill sets then there will be one entry in table 1 and 5 entry in table 2(For skill set).For each entry in table 2 there will be 6 entry in table 3(for each month).I need to write a query which would display
Group name nov2006 dec2006 jan2007 feb2007 mar2007 apr2007
Gr1 10 15 21 17 18 22--These are sum of man month of all skill set for a particular groupIf Gr 2 is of 9 months then it would disply all the information in respective months.i.e for group 2 nine months information and group 1 six months information
Pls help
Thanks in advance

How to make the fields of table clickable?

Hi Experts,
I have created one RFC based WD program. We are displaying data in a table. Now I have to make some of the fields of table clickable.
When the user will click on some of the fields, another RFC should be called.
How I can do so?
Regards,
Gary

hi
when you try to select the attributes of the table that has to be populated
you may have to right click on the rootuicontainer and select apply template and select table
and select the attributes from the node that has to be populated in the table and click next
and you can find the attributes name and textview which is by default that would be shown inthe table
instead you can change the textview and select from the dropdown select the linktoaction and linktourl
and or you can go other way as add a new column to the table and select buttons to the table .
and for each each row and on click of the button you can call the RFC .
Thanks
