AddChooseFromList in Matrix

Question

With this code, I create a textbox with search option. But how to do this for all the lines of a column of the Matrix? I want to be able to do this research study in each row of the matrix, Naque column.
        SAPbouiCOM.EditText oEdit = null;
        SAPbouiCOM.FormCreationParams oCP = null;
        oCP = ((SAPbouiCOM.FormCreationParams)   
       (SBO_Application.CreateObject(SAPbouiCOM.BoCreatableObjectType.cot_FormCreationParams)));
        oCP.UniqueID = "CFL1";
        oCP.FormType = "CFL1";
        oCP.BorderStyle = SAPbouiCOM.BoFormBorderStyle.fbs_Sizable;
        oForm.DataSources.UserDataSources.Add("EditDS", SAPbouiCOM.BoDataType.dt_SHORT_TEXT, 254);
        AddChooseFromList();
        //  Adding a text box
        oItem = oForm.Items.Add("EditTxt", SAPbouiCOM.BoFormItemTypes.it_EDIT);
        oItem.Left = 147;
        oItem.Top = 170;
        oItem.LinkTo = "StaticTxt";
        oEdit = ((SAPbouiCOM.EditText)(oItem.Specific));
        oEdit.DataBind.SetBound(true, "", "EditDS");
        oEdit.ChooseFromListUID = "CFL1";
        oEdit.ChooseFromListAlias = "ItemName";

Hy Harley,
I try to explain better.
Excuse me for my English.
Correct me if I made a mistake.
You want add a ChooseFromList to a Matrix Column. Right?
You also know how create a ChooseFromList. Right? There are another thread owened by you where you learn it. See in the code inside your AddChooseFromList() method.
So the steps are the following:
1) In the form you need to add a Matrix, not an EditText like the first snippet you post.
1.a) with the reference to the form oForm, access to the ItemsCollection oForm.Items and use the method .Add() in order to add the Matrix. This is shown on the first part of my snippet.
oItem = (SAPbouiCOM.Item)(oForm.Items.Add("MTX01", SAPbouiCOM.BoFormItemTypes.it_MATRIX));
oMatrix = (SAPbouiCOM.Matrix)(oItem.Specific);
2) You need to add some columns to the matrix. For example you should add the CardCode, the CardName and other information
oColumn = oMatrix.Columns.Add("CCODE", SAPbouiCOM.BoFormItemTypes.it_EDIT);
oColumn = oMatrix.Columns.Add("CNAME", SAPbouiCOM.BoFormItemTypes.it_EDIT);
2.a) So you have said: "Add two columns of Edit elements and call this columns respectively CCODE and CNAME"
3) Now you need to attach the ChooseFromList you made,  to your column (In SAP B1 you can't attach a ChooseFromList to a single cell so we can dispel you initial doubt).
3.a) Suppose you made two ChooseFromList named CFL01 and CFL02 for the Business Partner. (I suppose they were made in your AddChooseFromList() method), so we need to add just two rows of code for each matrix column.
// THE CODE WE SEEN BEFORE
oColumn = oMatrix.Columns.Add("CCODE", SAPbouiCOM.BoFormItemTypes.it_EDIT);
// THE CODE TO ATTACH THE CHOOSEFROMLIST
oColumn.ChooseFromListUID = "CFL01"; // The unique identifier of the ChooseFromList you want attach to the column
oColumn.ChooseFromListAlias = "CardCode";
// THE CODE WE SEEN BEFORE
oColumn = oMatrix.Columns.Add("CNAME", SAPbouiCOM.BoFormItemTypes.it_EDIT);
// THE CODE TO ATTACH THE CHOOSEFROMLIST
oColumn.ChooseFromListUID = "CFL02";
oColumn.ChooseFromListAlias = "CardName";
There are no difference between creation of ChooseFromList for and EditText and a ChooseFromList for a Column in a Matrix.
In your first snippet the Matrix doesn't appear, the columns didn't appears.
Then in your Item Event Handler, you need only to refers to the cell instead of the EditText.
I think to have give you the necessary code to understand the process and I hope to have well explained it to you. There are also an example on the .chm help files. Please search for the Column object and observe it's Methods and Properties.
In the case my explaination is not clear please excuse me but probably I have not well understand your real difficult.
Hope this helps.
Regards
Carmine
