binding and grouping OptionButtons

Mattia Ryffel

Hi,

Im trying to bind and group some Optionbuttons by code.
I usually do this by xml, and works fine. Here i've a problem with grouping and binding to the datasource.
I cant group nor databind the optionbuttons before the form add or it leads to a nullpointer exception, but if i do that after the form load nothing happens even if i reload the form...

any hint? what i'm doing wrong?

        swaForm = Form.CreateNewForm("SampleForm", "Sample" + SwissAddonFramework.Utils.UniqueStringGenerator.Next(2));
        
        //  Set form width and height
        swaForm.Height = 305;
        swaForm.Width = 600;
        swaForm.Value = "UI Grid sample";

        //  Option buttons
        //  Create a user Datasource for the option buttons
        swaUserDS = UserDatasource.CreateNew();
        swaUserDS.Length = 1;
        swaUserDS.DataSourceType = UserDatasource.DataType.ShortText;
        swaUserDS.UniqueID = "OpBtnDS";
        swaForm.AddUserDatasource(swaUserDS);

        //  No Grouping
        OptionButton optNo = OptionButton.CreateNew("optNo");
        optNo.Left = 480;
        optNo.Top = 160;
        optNo.Value = "No grouping";          
        swaForm.AddItem(optNo);

        // CardCode
        OptionButton optCard = OptionButton.CreateNew("optCard");
        optCard.Left = 480;
        optCard.Top = 180;
        optCard.Value = "Card Code";   
        swaForm.AddItem(optCard);
  
        //Load the form
        swaForm.Load();

        optNo.DataBind.SetBind(true, "OpBtnDS"); 
        optCard.GroupWith("optNo");
        optCard.DataBind.SetBind(true, "OpBtnDS");

Hello Mattia,

I think you have first to bind the OptionButton before Grouping it.

optCard.GroupWith("optNo");
optCard.DataBind.SetBind(true, "OpBtnDS");

change to:

optCard.DataBind.SetBind(true, "OpBtnDS");
optCard.GroupWith("optNo");

have you got a sample? or just specify the order of actions to follow...

create form
add buttons to form
add ds to form
form.load
bind
group

this order gives me:
Not allowed when the datasource is already loaded in SAP

i think i tried all the possible combinations of the actions listed above

Hello Mattia, this should work:

Form frm = Form.CreateNewForm("test", SwissAddonFramework.Utils.UniqueStringGenerator.Next())
frm.Value = "Test form"

Dim usdSalesPrice As UserDatasource = UserDatasource.CreateNew("usdSP")
frm.AddUserDatasource(usdSalesPrice)

OptionButton optOldSalesPrice = OptionButton.CreateNew("optOldSP")
optOldSalesPrice.Value = "Sales  price old"
optOldSalesPrice.DataBind = DataBind.CreateNew("usdSP")
optOldSalesPrice.DataBind.DataBound = True
frm.AddItem(optOldSalesPrice)

optNewSalesPrice = OptionButton.CreateNew("optNewSP")
optNewSalesPrice.Value = "Sales price"
optNewSalesPrice.DataBind = DataBind.CreateNew("usdSP")
optNewSalesPrice.DataBind.DataBound = True
frm.AddItem(optNewSalesPrice)

frm.Load()
optNewSalesPrice.GroupWith(optOldSalesPrice.UniqueID)

Attentions its VB .Net code ! But in C# its the same, only ; are missing ;)
