Restrict user to select next row in jqgrid - jqgrid

I am using jqgrid in my project.I have requirement that when user select row and click on edit button of inline toolbar control and modify any data in cell after that instead of click on Save button of inline toolbar control user click(select) any other row at that time.I want to show user message like
Wants to save/discard the modified data
if user click on Save button of message dialog then save the data otherwise discard the data.So please let me know how can I implement it.Till user don’t click on save or discard button don’t select the next row on which user click.

First of all you should use restoreAfterSelect: false option of inlineNav (if you use inlineNav). Seconds you can use beforeSelectRow to implement the required behavior and to call saveRow or restoreRow depend on the user choice.
The simplest implementation of beforeSelectRow could be the following:
beforeSelectRow: function (rowid) {
var $self = $(this),
savedRowInfos = $self.jqGrid("getGridParam", "savedRow"),
editingRowId = savedRowInfos == null || savedRowInfos.length < 1 ?
null : savedRowInfos[0].id;
if (editingRowId != null && editingRowId !== rowid) {
if (confirm("Do you want to save the changes?")) {
$self.jqGrid("saveRow", editingRowId);
} else {
$self.jqGrid("restoreRow", editingRowId);
}
}
}
I used confirm method above. You can see the working code on the demo.
Alternatively one can create asynchronous dialog using jQuery UI dialog for example. Then the code of beforeSelectRow could be the following:
beforeSelectRow: function (rowid) {
var $self = $(this),
savedRowInfos = $self.jqGrid("getGridParam", "savedRow"),
editingRowId = savedRowInfos == null || savedRowInfos.length < 1 ?
null : savedRowInfos[0].id;
if (editingRowId == null || editingRowId === rowid) {
return true; // allow selection
}
$("#dialog-confirm").dialog({
resizable: false,
height: "auto",
width: 650,
modal: true,
buttons: {
"Save the changes": function () {
$(this).dialog("close");
$self.jqGrid("saveRow", editingRowId);
$self.jqGrid("setSelection", rowid);
},
"Discard the changes": function () {
$(this).dialog("close");
$self.jqGrid("restoreRow", editingRowId);
$self.jqGrid("setSelection", rowid);
},
"Continue editing": function () {
var tr = $self.jqGrid("getGridRowById", editingRowId);
$(this).dialog("close");
setTimeout(function () {
$(tr).find("input,textarea,select,button,object,*[tabindex]")
.filter(":input:visible:not(:disabled)")
.first()
.focus();
}, 50);
}
}
});
return false; // prevent selection
}

jqGrid afterclickPgButtons skip the line where isLeaf non is TRUE?

I use jqGrid 4.9.3-pre - free jqGrid by Oleg.
I use:
contextmenu
treegrid
form Edit
multiselect: false
Code
treeGrid:true,
ExpandColumn:'name',
treedatatype:"json",
treeGridModel:"adjacency",
treeReader:{
level_field: "level",
parent_id_field: "parent",
leaf_field: "isLeaf",
expanded_field: "expanded",
loaded:true,
},
loadonce: false
How to If isLeaf is TRUE skip the line and go to the next line where isLeaf non is TRUE?
Navigation buttons of Edit form have no special interface which could allow to skip some rows, but one can use onclickPgButtons to prevent the navigation to the next/previous row and to simulate the click on the same button immediately after that. It's important to understand that jqGrid contains hidden field in the form with the id="id_g", which will be used by form editing as the rowid of the current editing row. Thus one can change the value of the hidden field before simulation of the click.
The corresponding implementation of the onclickPgButtons callback could be the following:
onclickPgButtons: function (buttonName, $form, rowid) {
var $self = $(this),
iRow = $self.jqGrid("getGridRowById", rowid).rowIndex,
isLeaf = $self.jqGrid("getGridParam", "treeReader").leaf_field,
rows = this.rows,
nRows = rows.length,
iInc = buttonName === "next" ? 1 : -1,
isNextRowVisibleLeaf = function () { // iRow - the current row
var $nextRow = $(rows[iRow + iInc]),
rowidNext = $nextRow.attr("id");
if (rowidNext != null) {
var nextItem = $self.jqGrid("getLocalRow", rowidNext);
if (nextItem != null && nextItem[isLeaf] && $nextRow.css("display") !== "none") {
return true;
}
}
return false;
},
$button = $(buttonName === "next" ? "#nData" : "#pData");
if (isNextRowVisibleLeaf()) {
return true; // nothing to do
}
// we need to fix the row, which the next row is visible leaf
while (iRow < nRows && iRow > 0) {
iRow += iInc;
if (isNextRowVisibleLeaf()) {
// set the value of hidden field of the form
// to the id of the found row and simulate the click
// on the same navigation button
$form.find("#id_g").val($(rows[iRow]).attr("id"));
setTimeout(function () {
$button.click();
}, 50);
return false;
}
}
return false;
}

MVVM-KendoNumericTextBox restore previous value without triggering 'change' twice

I'm using Kendo MVVM and I have a kendo numerictextbox bound to a kendo observable.
All I want is: when the user changes value, a confirm should pop saying something like 'are you sure?' if yes -> no problem, go on.
if no -> NOTHING should happen!
In theory it sounds simple as that... but I found 3 major issues:
1) numerictextbox only got 2 events: spin and change... so any idea of using keypress/focus/or any other event is discarded.
2) So tried using the change event... but I can't preventDefault! Another try was to save previous value and restore it back in case of 'no answer' but this brings me to trigger event change TWICE!
3) Any other model field who is 'observing' the numerictextbox will change before I even answer the confirm box... And I absolutely don't want this!
P.S. I also got a dropdownlist and a datepicker that must work in the same way!
Help please!
Provided a fast example: http://dojo.telerik.com/EyItE
Here you can see how the numericbox2 (who is observing numericbox1 and is computed) changes itself before the user answer yes/no (problem 3)
and keypress/focus/preventDefault doesn't work.
here is an answer about binding events not supported by default:
Kendo MVVM and binding or extending custom events
For preventDefault (or "reverting" the value). I tried to store the previous value as you suggested and it is does not fire twice:
var viewModel = kendo.observable({
myItem: {
// fields, etc
myNumericBox: 10,
myNumericBox2: function () {
return viewModel.get("myItem.myNumericBox")*2;
},
tmp: 10
},
onChange: function (e) {
if ( confirm("are you sure?")) {
viewModel.set("myItem.tmp", viewModel.get("myItem.myNumericBox"));
}
else {
viewModel.set("myItem.myNumericBox", viewModel.get("myItem.tmp"));
}
},
tryf: function () {
alert("hello!"); // doesn't trigger
},
tryk: function() {
alert("hello2!"); // doesn't trigger
}
});
I solved with a custom binding that ask you a confirm between html widget change -> model update.
kendo.data.binders.widget.valueConfirm = kendo.data.Binder.extend({
init: function (widget, bindings, options) { // start
kendo.data.Binder.fn.init.call(this, widget.element[0], bindings, options);
this.widget = widget;
this._change = $.proxy(this.change, this);
this.widget.bind("change", this._change); // observe
},
refresh: function () { // when model change
if (!this._initChange) {
var widget = this.widget;
var value = this.bindings.valueConfirm.get(); // value of the model
if (widget.ns == ".kendoDropDownList") { // for the dropdown i have to use select
widget.select(function (d) {
return d.id == value.id;
});
}
else widget.value(value); // update widget
}
},
change: function () { // when html item change
var widget = this.widget;
if (widget.ns == ".kendoDropDownList") var value = widget.dataItem(); // for dropdown i need dataitem
else var value = widget.value();
var old = this.bindings.valueConfirm.get();
this._initChange = true;
// I want to bypass the confirm if the value is not valid (for example after 1st load with blank values).
if (old == null || old == 'undefined' || old == 'NaN') this.bindings.valueConfirm.set(value); // Update the View-Model
else {
if (confirm("Are you sure?")) {
this.bindings.valueConfirm.set(value); // Update the View-Model
}
else {
this._initChange = false;
this.refresh(); // Reset old value
}
}
this._initChange = false;
},
destroy: function () { // dunno if this is useful
this.widget.unbind("change", this._change);
}
});

Drag rows in jqGrid

I want to implement draggable rows feature in jqGrid and it's working also using option
$('#MyGrid').jqGrid('gridDnD', {
connectWith: '#MyGrid2'});
Now, my client want to show "Drag here" text in target grid row at the position where the row will be dragged from existing to new one, how can I show this text while dragging row from source to target? Any help is appreciated...
I find your question interesting. So I modified the old demo from the answer and created the demo which demonstrates a possible implementation. The grid during dropping looks like on the picture below:
It uses the following code
$("#grid1").jqGrid("gridDnD", {
connectWith: "#grid2",
drop_opts: {
activeClass: "",
hoverClass: ""
},
onstart: function (ev, ui) {
ui.helper.addClass("ui-widget ui-widget-content")
.css({
"font-size": "11px",
"font-weight": "normal"
});
},
onstop: function (ev, ui) {
$("#dragHelper").hide();
},
droppos: "afterSelected", // "beforeSelected"
beforedrop: function (e, ui, getdata, $source, $target) {
var names = $target.jqGrid("getCol", "name2");
if ($.inArray(getdata.name2, names) >= 0) {
// prevent data for dropping
ui.helper.dropped = false;
alert("The row \"" + getdata.name2 + "\" is already in the destination grid");
}
$("#dragHelper").hide();
$("#grid2").jqGrid("setSelection", this.id, true, e);
},
ondrop: function (ev, ui, getdata) {
var selRow = $("#grid2").jqGrid("getGridParam", "selrow"),
$tr = $("#" + $.jgrid.jqID(selRow));
if ($tr.length > 0) {
$("#grid2").jqGrid("setSelection", $("#grid2")[0].rows[$tr[0].rowIndex + 1].id, true);
}
}
});
// make every row of the destination grid droppable and select row on over
$("#grid2 tr.jqgrow").droppable({
hoverClass: "ui-state-hover",
over: function (e, ui) {
$("#grid2").jqGrid("setSelection", this.id, true, e);
$("#dragHelper").show().position({my: "right center", at: "left bottom", of: $(this)});
}
});
I reserve some place for the tooltip "Drag here ↣" on the left of the grid and marked the row under the moved row additionally to make the position of the dropped row mostly clear. I used free jqGrid which have support of "afterSelected" and "beforeSelected" position of addRowData originally suggested in the answer. So I used droppos: "afterSelected". The dropped rows will be inserted after the selected row.

How to set Row data using rowid and column name in jQgrid

I've added a custom icon using below code in jqgrid Actions column. When the cutom icon is clicked, a pop up is opened with Textarea, Save and Close buttons. When I click Save button I wanted to save the text entered in textarea to a hidden field column in jQgrid. I tried 'setRowData' and 'setCell' properties but nothing works. Am I missing something here?
afterInsertRow: function (rowid, rowdata, rowelem) {
$(this).triggerHandler("afterInsertRow.jqGrid", [rowid, rowdata, rowelem]);
//...//
//Start: Code for Notes Icon in Actions column
var iCol = getColumnIndexByName(grid, 'actions');
$(this).find(">tbody>tr#" + rowid + ">td:nth-child(" + (iCol + 1) + ")")
.each(function () {
$("<div>", {
title: "Custom",
mouseover: function () {
$(this).addClass('ui-state-hover');
},
mouseout: function () {
$(this).removeClass('ui-state-hover');
},
click: function (eve) {
$("#change_dialog").dialog({
buttons: {
'Save': function () {
var selRow = $(eve.target).closest("tr.jqgrow").attr("id");
var txtNotes = $("#mytext").val();
$("#gridJQ").setRowData(selRow, { 'notesHidden': txtNotes });
$("#gridJQ").jqGrid('setCell', selRow, 'notesHidden', txtNotes);
$("#gridJQ").jqGrid('setRowData', selRow, 'notesHidden', txtNotes);
$(this).dialog("close");
},
'Close':function() {
$(this).dialog("close");
}
}
});
return false;
}
}
).css({ "margin-right": "5px", float: "left", cursor: "pointer" })
.addClass("ui-pg-div ui-inline-custom")
.append('<span class="ui-icon ui-icon-document"></span>')
.prependTo($(this).children("div"));
});
Instead of using this code to get the row
var selRow = $(eve.target).closest("tr.jqgrow").attr("id");
Try something a more direct such as
var selRow = $("#gridJQ").jqGrid('getGridParam', 'selrow');
Or even just var selRow = rowid.
Does that help at all?

Refers to: jqgrid: how to set toolbar options based on column value in row selected

my question refers to http://goo.gl/f0Boc
The code works fine for me, but now I want to enable/disable the "Edit-Button" when the value in a cell is "Yes" or "No".
In this example is written:
// you can use getCell or getRowData to examine the contain of
// the selected row to decide whether the row is editable or not
I need an explanation how I could change the code so that the code runs with jqGrid('getCell',rowid,'cellContent')?
What I need is if cellContent is "Yes" then disable "Edit-Button".
Thanks in advance for your efforts,
best regards
Stephan

I modified the referenced demo for you. The main part of the code is the following
onSelectRow: function (rowid) {
var thisId = $.jgrid.jqID(this.id),
isCompleted = $(this).jqGrid("getCell", rowid, "isCompleted");
// you can use getCell or getRowData to examine the contain of
// the selected row to decide whether the row is editable or not
if (isCompleted !== "Yes") {
// eneble the "Edit" button in the navigator
$("#edit_" + thisId).removeClass('ui-state-disabled');
$("#del_" + thisId).removeClass('ui-state-disabled');
} else {
// unselect previous selected row
// disable the "Edit" and "Del" button in the navigator
$("#edit_" + thisId).addClass('ui-state-disabled');
$("#del_" + thisId).addClass('ui-state-disabled');
}
}
You can see new demo here.
