Hello Tony,

I'm trying to delete the rows selected by the user.

However, I've tryied almost all combinations ofthe following loop, without achieving that after it "getGridParam('selarrrow')" eguals zero.

How should I do it ?

Here my code ...

Thanks in advance

	var filas = jQuery("#tabla").getGridParam('selarrrow');
	if (filas == null) {
		return false;
	} 
	for(var i=filas.length-1; i>=0; i--) {
		alert(filas+'(length='+filas.length+') current: '+filas[i]);
		jQuery("#tabla").delRowData(filas[i]);
		jQuery("#tabla").setSelection(filas[i]);
	}
	alert(jQuery("#tabla").getGridParam('selarrrow'));

Please tell me what is wrong here - you can not catch the selected rows or you can not delete them?

For professional UI suites for Java Script and PHP visit us at our commercial products site - guriddo.net - by the very same guys that created jqGrid.

I have a custom button, which status toggles on (un)selecting a rows. Therefor, if the user intends to delete some rows, the selection should remain empty in the end.

But the fact is that if I first delete the rows, then I can't unselect them, and they stay available in the selarrow. (I should have mention that I use multiselect)

On the other side, if I first unselect the rows, they are correctly removed from the selarrow, which makes deletion impossible …

A workaround is to copy the array while unselecting the rows, and to loop another time for deletion…

 var filas = jQuery("#tabla").getGridParam('selarrrow');
 	if (filas == null) {
 		return false;
 	}
 	 
	var filas_delete = [];
 	var filas_select = filas;
 	
 	for(var i=filas_select.length-1; i>=0; i–) {
 		filas_delete[i] = filas_select[i];
 		alert(filas_select+'(length='+filas_select.length+') current: '+filas_select[i]+
 			'\\n my new array: '+filas_delete
 		);
 		jQuery(”#tabla”).setSelection(filas_select[i]);
 	}
 	for(var i=filas_delete.length-1; i>=0; i–) {
 		alert(filas_delete+'(length='+filas_delete.length+') current: '+filas_delete[i]);
 		jQuery(”#tabla”).delRowData(filas_delete[i]);
 	}

Hello Tony,

I'm so sorry : i just seen the resetSelection() function ....

Then my problem is just solved : the following code makes all the work :

	var filas = jQuery("#tabla").getGridParam('selarrrow');
	if (filas == null) {
		return false;
	}
	for(var i=filas.length-1; i>=0; i--) {
		jQuery("#tabla").delRowData(filas[i]);
	}
	jQuery("#tabla").resetSelection();

Thank you very much for this plugin and for you atention !

greetings !
