Paging 2.5

Alex

I have used the following code bit from you to develop paging in 2.02, it worked nice, but in 2.5 setRowOffset(x) start in the x row, meaning that the grid seams empty on page 2.

The reason why i can see this is offset is 32 but there is space enough to see 34, so page 2 only shows 2 rows in row 33 and 34.

Try your own example in version 2.5 and you will se the problem.

var obj = new AW.UI.Grid;
obj.setCellData(function(col, row){return col + "." + row});
obj.setHeaderText("header");

obj.setColumnCount(10);
obj.setRowCount(10);

document.write(obj);

document.write("<br>");

var button = new AW.UI.Button;
button.setControlText("Next");
document.write(button);

button.onControlClicked = function(){
var x = obj.getRowOffset();
obj.setRowOffset(x+10);
obj.refresh();
}

Armit,
The new (and fast) rendering engine in version 2.5 requires to do little changes to Alex's paging-offset sample:
- disable VirtualMode
- use rowsTemplate refresh instead of a full-grid refresh.

var obj = new AW.UI.Grid; 
obj.setCellData(function(col, row){return col + "." + row}); 
obj.setHeaderText("header"); 

obj.setColumnCount(10); 
obj.setRowCount(1000); //real rows

var totalrows = obj.getRowCount();
obj.setRowCount(10); //paged rows

obj.setVirtualMode(false);
document.write(obj); 

document.write("<br>"); 

var button = new AW.UI.Button; 
button.setControlText("Next"); 
document.write(button); 

button.onControlClicked = function(){ 
var x = obj.getRowOffset(); 
if ( x < totalrows ){ 
obj.setRowOffset(x+10);
obj.getRowsTemplate().refresh();
} 
}

Carlos,

Thanks for the answer, where do you find this information about changes from 2.02 to 2.5, so that i don't have to bother people on this board whit questions i can find my self, or there are solutions to all the workarounds in my code.

Thanks

Sorry to say, I don't keep any magical book , it's all based on search the forum, Docs, Alex's postings, and also my own experience doing loooots of testing & experimenting things for a private app plus a personal proyect that someday...... ;-)
Anyway its not that difficult to reach a mid "level" after learning some "thricks", but I agree that takes it's time, and mostly doing "search & test" - what else - it is S*ftw*r* - :-(

Sorry, I did not publish the list of all changes yet (still working on it). Should be ready in 2-3 days.

The problem with rowOffset is now fixed in AW 2.5.1
