Hi,
Does anyone know a way to limit the row number for a grid? Normally, users may enter as many rows as they wish, but what if they are expected to enter no more than 5 rows for instance? How can we accomplish that requirement?
I tried, controlling the maximum rows in a javascript function, which I assigned to grid's onaddrow event. But it was no success, because the function fires after the row has been added.
Any clues?
Regards.

Problem solved. I've controlled the maximum number of lines in a function. After this maximum number has been reached, overwriting the addGridRow function of the grid with another function does the job.
Below is a sample code.

Code: Select all

function gridMaxRowsAlert(){
	alert("You've reached the maximum number of lines for this grid.");

}

function onAddNewRow(){
	var MAXROWS=8;
	var totalRows = Number_Rows_Grid("ItemList", "Amount");
	if (totalRows>=MAXROWS){
		getObject("ItemList").addGridRow=gridMaxRowsAlert;
		return false;
	}
	return true;
}

grid_ItemList.onaddrow=onAddNewRow;

Where are you placing this code to limit the # of rows in a Grid?

grid_ItemList.onaddrow=onAddNewRow;

Is it possible for you to explain the variable used in this above code. even code.

Hi,
Use the above code for limiting the grid rows.
Where we get number of rows from grid using getNumberRows.

Code: Select all

$('#grid_variable').onAddRow(function(){
	var MAXIMUMROWS=10;
	var  countOfRows=$('#grid_variable').getNumberRows();

               if(countOfRows>MAXIMUMROWS)
              {
	                  alert("You have reached the maximum lines");
                           $('#grid_variable').deleteRow();
                }
	});
