How to set the row index of the dynamically created ROW ( add another row just below the selected add button))
Hai folks,
I have a table with 7 rows.
The last column of each row has action buttons [add] and [delete]
Now when i click on add button of the first row, new row should get created below it. Now with the following code, new row is getting created at the end of all 7 row's. i.e. it is getting created as 8th row.
Any workaround??

}
You can add one row by passing rowindex from page to contoller and use below mentioned code:
public void addRow()
{
if(rowindex+1 < attendeeList.size())
attendeeList[rowindex + 1] = new Contact(AccountId = accounts.Id);
else
attendeeList.add(new Conact(AccountId = accounts.Id));
}

My code already does the action of add and delete. My requirement is,
When i click on the add button of the first row, Now row should be added in the secode row.
That is new row should have the index value 1.
You can add one row by passing rowindex from page to contoller and use below mentioned code:
public void addRow()
{
if(rowindex+1 < attendeeList.size())
attendeeList[rowindex + 1] = new Contact(AccountId = accounts.Id);
else
attendeeList.add(new Conact(AccountId = accounts.Id));
}
When i add the following code, it is giving me the NULL Pointer Exception
EXCEPTION
System.NullPointerException: Argument cannot be null.
Error is in expression '{!addRow}' in component <apex:commandButton> in page addrowsdynamicallynew: Class.workestimationDetailsNew.addRow: line 55, column 1
Class.workestimationDetailsNew.addRow: line 55, column 1
public void addRow(){ //addattendeeList = new List<Contact>(); // attendeeList.add(new Contact(AccountId = '00128000002rnbM')); rowIndex = Integer.valueOf(ApexPages.currentPage().getParameters().get('rowIndex')); if(rowindex+1 < attendeeList.size()) attendeeList[rowindex + 1] = new Contact(AccountId = '00128000002rnbM'); else attendeeList.add(new Contact(AccountId = '00128000002rnbM')); }Can you place assignTo attribute at line no.29 in vf page:
<apex:param name="rowIndex" value="{!rowNumber}" assignTo="{!rowIndex}"/>
Then use this value in function.
