Passing Multiple Records from one form to another through Args in Dynamics Ax 2012

In my last post, i posted on how to pass Record from one Form to another Form. Now i will pass multiple Record from one Form to another through Args.

The Scenario is when I select multiple grids in Form A, those records will be passed to FormB and there FormB will received the all those records and filter it and will show.

Step 1: Make one SampleTable which has three fields named (SIno, name, AddressCity).
Step 2: Make FormA with datasource as SampleTable and drag the datasource fields into the design Grid.
Step 3: Drag one button and override the click method and write the following code.
step 4: Make one Display menuitem of FormB.

void clicked()
{

int recordsCount;
SampleTable _sampleTable;
container con;
Args args;
str multiSelectString;
;

args = new Args();
recordsCount = SampleTable_ds.recordsMarked().lastIndex(); // gets the total records selected
_sampleTable = SampleTable_ds.getFirst(1);

while (_sampleTable)
{
// storing recid of selected field in container
con = conIns(con,1,_sampleTable.RecId);

// converting container to string with comma separated
multiSelectString = con2Str(con,’,’);

_sampleTable = SampleTable_ds.getNext(); // moves to next record
}
// passing string
args.parm(multiSelectString);
// calling menu item
new MenuFunction(menuitemDisplayStr(FormBMenuItem), MenuItemType::Display).run(args);
}

step 5: Make FormB with datasource as same table for which you take for Form A i.e., SampleTable and drag the fields in to the
Grid of design part.
step 7: write the following code in to the init method of FormB.

public void init()
{
container con;
int i;
str multipleRecords;
super();
// getting string value from caller
multipleRecords = element.args().parm();

// string to container
con = str2con(multipleRecords,”,”);

// for sorting
for(i = 1;i<= conLen(con) ;i++)
{
SampleTbl_ds.query().dataSourceTable(Tablenum(SampleTbl)).addRange(fieldNum(SampleTbl,RecId)).value(SysQuery::value(conPeek(con,i)));
}

}
Please select button property multiselect to “yes”

thanks and your feedback will be appreciated.
