This is my first experience with Slickgrid and I have configured slickgrid treeview example5 in my org. Unfortunately could not make collapsing work. After debugging one thing I noticed is onRowCountChanged event is not called.
Can anyone please help me her. Thanks in advance...
I wired the event on page as --
$(function () {
Visualforce.remoting.Manager.invokeAction(
'{!$RemoteAction.QuoteHandler_c.getQuoteItems}','{!quote.id}',
function(result, event) {
quoteItems = result;
prepateData();
// initialize the model
dataView = new Slick.Data.DataView({ inlineFilters: true });
dataView.beginUpdate();
dataView.setItems(data);
dataView.setFilter(myFilter);
dataView.endUpdate();
// initialize the grid
grid = new Slick.Grid("#myGrid", dataView, columns, options);
grid.onClick.subscribe(function (e, args) {
if ($(e.target).hasClass("toggle")) {
var item = dataView.getItem(args.row);
if (item) {
if (!item._collapsed) {
item._collapsed = true;
} else {
item._collapsed = false;
}
dataView.updateItem(item.id, item);
}
e.stopImmediatePropagation();
}
});
// wire up model events to drive the grid
dataView.onRowCountChanged.subscribe(function (e, args) {
grid.updateRowCount();
grid.render();
});
dataView.onRowsChanged.subscribe(function (e, args) {
grid.invalidateRows(args.rows);
grid.render();
});
var h_runfilters = null;
// wire up the slider to apply the filter to the model
$("#pcSlider").slider({
"range": "min",
"slide": function (event, ui) {
Slick.GlobalEditorLock.cancelCurrentEdit();
if (percentCompleteThreshold != ui.value) {
window.clearTimeout(h_runfilters);
h_runfilters = window.setTimeout(dataView.refresh, 10);
percentCompleteThreshold = ui.value;
}
}
});
// wire up the search textbox to apply the filter to the model
$("#txtSearch").keyup(function (e) {
Slick.GlobalEditorLock.cancelCurrentEdit();
// clear on Esc
if (e.which == 27) {
this.value = "";
}
searchString = this.value;
dataView.refresh();
})
}
);
})
Thanks for your help...
I figured it out. The error was with myFilter function. Because of which the number of rows always returned same hence onRowsCountChanged not called.

I am trying to handle the server error when creating/updating/deleting item from kendo grid. But when a error is thrown, the kendo grid closes no matter what.
function kendo_error_handler(e) {
if (e.errors) {
var message = "Errors:\n";
$.each(e.errors, function (key, value) {
if ('errors' in value) {
$.each(value.errors, function () {
message += this + "\n";
});
}
showErrorMessages(key, message);
});
//this does not work
var grid = this;
gird.one("dataBinding", function (e) {
e.preventDefault();
});
}
}
Does anybody have any other solution? e.preventDefault() doesn't work either.
This worked for me. Just in case anybody needs this.
function kendo_error_handler(gridName) {
return function (e) {
if (e.errors) {
var grid = $('#'+gridName).data("kendoGrid");
grid.one("dataBinding", function (ev) {
ev.preventDefault();
var message = "Errors:\n";
$.each(e.errors, function (key, value) {
if ('errors' in value) {
$.each(value.errors, function () {
message += this + "\n";
});
}
showErrorMessages(key, message);
});
});
}
else {
$("#errorContainer").text("");
}
}
}
is it cause it says " gird.one(" instead of "grid.one("
I have checkbox in Kendo grid. Once i click on Checkbox it always focus the top cell in Kendo Grid. Below is code for Kendo grid that I am binding to checkbox value on checkbox click event in Kendo Grid
$("#contactgrid").on('click', '.chkbx', function () {
var checked = $(this).is(':checked');
var grid = $('#contactgrid').data().kendoGrid;
var rowIdx = $("tr", grid.tbody).index(row);
var colIdx = $("td", row).index(this);
// grid.tbody.find("tr").eq(rowIndex).foucs(); This doesn't work
var dataItem = grid.dataItem($(this).closest('tr'));
dataItem.set('IsSelected', checked);
});
I can get the row index and cell Index in click event but I was not able to figure out to focus the specific cell.
Thanks!
When you want to edit Grid with checkbox then I would suggest you to use the approach from this code library. No matter it uses the MVC extensions open Views/Home/Index.cshtml and see how the template is defined and the javascript used after initializing the Grid.
Here it is
Column template:
columns.Template(#<text></text>).ClientTemplate("<input type='checkbox' #= IsAdmin ? checked='checked':'' # class='chkbx' />")
.HeaderTemplate("<input type='checkbox' id='masterCheckBox' onclick='checkAll(this)'/>").Width(200);
<script type="text/javascript">
$(function () {
$('#persons').on('click', '.chkbx', function () {
var checked = $(this).is(':checked');
var grid = $('#persons').data().kendoGrid;
var dataItem = grid.dataItem($(this).closest('tr'));
dataItem.set('IsAdmin', checked);
})
})
function checkAll(ele) {
var state = $(ele).is(':checked');
var grid = $('#persons').data().kendoGrid;
$.each(grid.dataSource.view(), function () {
if (this['IsAdmin'] != state)
this.dirty=true;
this['IsAdmin'] = state;
});
grid.refresh();
}
</script>
I struggled with this. I essential refocused the cell as shown below. There's plenty of room for improvement in the Kendo grid client-side API. Hopefully my helper methods below will help people out.
var $row = getRowForDataItem(this);
var $current = getCurrentCell($row);
var currentCellIndex = $row.find(">td").index($current);
this.set('PriceFromDateTime', resultFromDate);
$row = getRowForDataItem(this);
var grid = getContainingGrid($row);
//select the previously selected cell by it's index(offset) within the td tags
if (currentCellIndex >= 0) {
grid.current($row.find(">td").eq(currentCellIndex));
}
//Kendo grid helpers
function getColumn(grid, columnName) {
return $.grep(grid.columns, function (item) {
return item.field === columnName;
})[0];
}
function getRowForDataItem(dataItem) {
return $("tr[data-uid='" + dataItem.uid + "']");
}
function getCurrentCell($elem) {
return getContainingGrid($elem).current();
}
function getContainingDataItem($elem) {
return getDataItemForRow(getContainingRow($elem));
}
function getContainingCell($elem) {
return $elem.closest("td[role='gridcell']");
}
function getContainingRow($elem) {
return $elem.closest("tr[role='row']");
}
function getContainingGrid($elem) {
return $elem.closest("div[data-role='grid']").data("kendoGrid");
}
function getGridForDataItem(dataItem) {
return getContainingGrid(getRowForDataItem(dataItem));
}
function getDataItemForRow($row, $grid) {
if (!$grid) $grid = getContainingGrid($row);
return $grid.dataItem($row);
}
function getMasterRow($element) {
return $element.closest("tr.k-detail-row").prev();
}
function getChildGridForDataItem(dataItem) {
return getRowForDataItem(dataItem).next().find("div.k-grid").data("kendoGrid");
}
function getMasterRowDataItem($element) {
var $row = getMasterRow($element);
return getDataItemForRow($row);
}
I'm using this demo to display text and dropdown list filters in the columns of a JqGrid. The grid has a remote data source and with each sort, filter, or page view etc, it grabs the data from the remote source.
The problem I am having is that when the new data arrives, the grid is refreshed, and the filters revert to default. I've looked at a few examples by Dr Oleg but I can't get it to work with remote data and persistence. Any setting of datatype to "local" or loadonce to true breaks the remote datasource.
Does anyone have any ideas of how to get this to work?
I've tried the following, but as I said, this stops the JqGrid from making API requests:
loadComplete: function () {
var $this = $(this);
var postfilt = $this.jqGrid('getGridParam', 'postData').filters;
var postsord = $this.jqGrid('getGridParam', 'postData').sord;
var postsort = $this.jqGrid('getGridParam', 'postData').sidx;
var postpage = $this.jqGrid('getGridParam', 'postData').page;
console.log(postfilt);
console.log(postsord);
console.log(postsort);
console.log(postsort);*/
if ($this.jqGrid("getGridParam", "datatype") === "json") {
setTimeout(function () {
$this.jqGrid("setGridParam", {
datatype: "local",
postData: { filters: postfilt, sord: postsord, sidx: postsort },
search: true
});
$this.trigger("reloadGrid", [{ page: postpage}]);
}, 25);
}
}
I think the issue has something to do with the select2 dropdown menus. Here you can see it destroys the filter menu and recreates it.
var options = colModelOptions, p, needRecreateSearchingToolbar = false;
if (options != null) {
for (p in options) {
if (options.hasOwnProperty(p)) {
if (options[p].edittype === "select") {
options[p].editoptions.dataInit = initSelect2;
}
if (options[p].stype === "select") {
options[p].searchoptions.dataInit = initSelect2;
}
$grid.jqGrid("setColProp", p, options[p]);
if (this.ftoolbar) { // filter toolbar exist
needRecreateSearchingToolbar = true;
}
}
}
if (needRecreateSearchingToolbar) {
$grid.jqGrid("destroyFilterToolbar");
$grid.jqGrid("filterToolbar", filterToolbarOptions);
}
}
If there was a way this could be done just once per JqGrid load rather than per every request, then that may be a step in the right direction.
The answer to this was quite simple, it just didn't present itself to me until the next morning. I simply wrapped the code that built the search bar in a boolean check, so that it only loaded once.
// somewhere in the class
var gridLoaded = false;
// and in the JqGrid initialization
loadComplete: function (response) {
if (!gridLoaded) {
var options = colModelOptions, p, needRecreateSearchingToolbar = false;
if (options != null) {
for (p in options) {
console.log(p);
if (options.hasOwnProperty(p)) {
if (options[p].edittype === "select") {
options[p].editoptions.dataInit = initSelect2;
}
if (options[p].stype === "select") {
options[p].searchoptions.dataInit = initSelect2;
}
$(this).jqGrid("setColProp", p, options[p]);
if (this.ftoolbar) { // filter toolbar exist
needRecreateSearchingToolbar = true;
}
}
}
if (needRecreateSearchingToolbar) {
$(this).jqGrid("destroyFilterToolbar");
$(this).jqGrid("filterToolbar", filterToolbarOptions);
}
}
gridLoaded = true;
}
}
Thanks again to Dr Oleg for the help.
I have this in grid settings:
var gridLayoutRepository = new GridLayoutRepository();
settings.ClientLayout = (s, e) =>
{
Debug.Write(e.LayoutData);
if (e.LayoutMode == ClientLayoutMode.Loading)
{
e.LayoutData = gridLayoutRepository.Load();
}
else
{
gridLayoutRepository.Save(e.LayoutData);
}
};
I want to have one button for saving gridstate in database and one button for resetting it. Can you help me?
This is possible this way. In grid settings must save grid state:
settings.ClientLayout = (s, e) =>
{
if (e.LayoutMode == ClientLayoutMode.Loading)
{
if (Session["myGridState"] != null)
e.LayoutData = (string)Session["myGridState"];
}
else
Session["myGridState"] = e.LayoutData;
};
Then on button click you should save grid state like this:
<script type="text/javascript">
function SaveLayoutData() {
$.getJSON("#Url.Action("SaveLayoutData", "MyController" })", null,
function (result) {
if(result == 'success') {
alert("Layout save success");
}
});
}
</script>
In Controller:
public JsonResult SaveLayoutData()
{
_gridStateRepository.Save(Session["myGridState"]);
return Json("success", JsonRequestBehavior.AllowGet);
}
When you are loading grid you should load grid state from database and write it in Session["myGridState"]
ok so im having a hard time hiding some layout sections (divs in my layout page and im using mvc3).
I have this js fragment which is basically the main logic:
$('.contentExpand').bind('click', function () {
$.cookie('right_container_visible', "false");
});
//Cookies Functions========================================================
//Cookie for showing the right container
if ($.cookie('right_container_visible') === 'false') {
if ($('#RightContainer:visible')) {
$('#RightContainer').hide();
}
$.cookie('right_container_visible', null);
} else {
if ($('#RightContainer:hidden')) {
$('#RightContainer').show();
}
}
as you can see, im hidding the container whenever i click into some links that have a specific css. This seems to work fine for simple tests. But when i start testing it like
.contentExpand click --> detail button click --> .contentExpand click --> [here unexpected issue: the line $.cookie('right_container_visible', null); is read but it doesnt set the vaule to null as if its ignoring it]
Im trying to understand whats the right logic to implement this. Anyone knows how i can solve this?
The simpliest solution is to create variable outside delegate of bind.
For example:
var rightContVisibility = $.cookie('right_container_visible');
$('.contentExpand').bind('click', function () {
$.cookie('right_container_visible', "false");
rightContVisibility = "false";
});
if (rightContVisibility === 'false') {
...
}
The best thing that worked for me was to create an event that can catch the resize of an element. I got this from another post but I dont remember which one. Anyway here is the code for the event:
//Event to catch rezising============================================================================
(function () {
var interval;
jQuery.event.special.contentchange = {
setup: function () {
var self = this,
$this = $(this),
$originalContent = $this.text();
interval = setInterval(function () {
if ($originalContent != $this.text()) {
$originalContent = $this.text();
jQuery.event.handle.call(self, { type: 'contentchange' });
}
}, 100);
},
teardown: function () {
clearInterval(interval);
}
};
})();
//=========================================================================================
//Function to resize the right container============================================================
(function ($) {
$.fn.fixRightContainer = function () {
this.each(function () {
var width = $(this).width();
var parentWidth = $(this).offsetParent().width();
var percent = Math.round(100 * width / parentWidth);
if (percent > 62) {
$('#RightContainer').remove();
}
});
};
})(jQuery);
//===================================================================================================
