By default multiselection is enabled and ng-grid displays checkboxes on the left side. How to keep multiselection but get rid of the checkboxes?
Set enableRowHeaderSelection to false.
$scope.gridOptions = {
...
enableRowHeaderSelection: false
...
};

I have a form in which fields are setting up in dropdown menu onChange handler: change() form fields.
Form submit button disabled: pristine || !valid || submitting.
I can try to set up value of dropdown menu field in initialValues in onChange. Is there any other way to ignore field pristinity?
I think you can :
To keep dirty form values when it reinitializes, you can set
keepDirtyOnReinitialize to true
from http://redux-form.com/6.6.3/examples/initializeFromState/
so when you are using
export default reduxForm({
// ...
keepDirtyOnReinitialize: true
})(MyForm);
I have a scenario where I have a Kendo dropdown, Kendo Datepicker as couple of columns in the grid.
On Add new record, the dropdown should be editable, on Edit mode, this drop down should be non Editable.
I have declared Grid to be Editable in declaration using
.Editable()
model.Field(p => p.CountryName).Editable(true); // where CountryName is kendo dropdown
I am trying to do on Edit this way,
function OnEdit(e) {
if (e.model.isNew() == false) {
e.model.fields["CountryName"].editable = false
}
THe behaviour I observe is Initially on load, Editable is set to true (due to cshtml declaration). When I click on Edit too, the drop down is Editable because of the page load flag that is set.
Even though OnEditmethod is executed and editable is set to false, the grid seems to have loaded before this code execution, hence editable =false is not reflected.
If I click on Edit second time, now the editable is set to false due to the previous call, Hence the dropdown is non editable as expected.
In Summary, the flag setting is not effective for the current action, but for the immediate next action. I am not sure if I have made it clear. Can you guys help?
Update - The other option I tried, during databind to the grid, I tried explicitly settign editable to false to all the grid data. My assumption here was only the loaded rows will have this field set to false. But in this case even the add new record takes Editable false.
var grid2 = $("#Gridprepayment").data("kendoGrid").dataSource.data(requiredData);
$.each(requiredData, function (i, row) {
var model = $("#Gridprepayment").data("kendoGrid").dataSource.at(i);
if (model) {
model.fields["CountryName"].editable = false;
}
});
The best way is to make the column editable .
e.g.
model.Field(d => d.CountryName).Editable(true);
and Onedit function, replace the inner html like mentioned below, for just to display it as label.
function OnEdit(e) {
e.container[0].childNodes['0'].innerHTML = e.model.CountryName;
}
Try disabling the kendo dropdown in the following manner:
function OnEdit(e) {
if (e.model.isNew() == false) {
$("#CountryName").data("kendoDropDownList").enable(false);
}
}
You can try this if you want to show the dropdownList as label in edit mode
function OnEdit(e) {
if(e.container.find("input").attr("id") === 'CountryName') {
this.closeCell();
}
}
Note: The above code was written considering "CountryName" as the id of the dropdown. Please change if the id is different.
I tried this which worked.
It's only a work around :
function OnEdit(e) {
if (e.model.isNew() == false) {
if (e.container.find("input").attr("id") === 'CountryName') {
e.container.find("td:eq(0)").html($("#CountryName").val());
}
}
}
Hello a have a simple question I have defined columns with property resizable: true.
How do I manage to let user re-size column with their mouse, like they will do in most grid control?
Columns are resizable by default, but you have to activate resizing on the whole grid by setting enableColumnResize to true in the grid options. See this Plunker.
$scope.gridOptions = {
data: 'myData',
enableColumnResize: true
};
Is there a way to toggle the multiselect option of a grid?
Changing the multiselect parameter of the grid and calling for a reload has the side-effect of leaving the header behind when disabling or not creating the header column if multiselect was not TRUE upon the grid creation.
The closest I have come is setting multiselect to TRUE upon grid creation and using showCol and hideCol to toggle: $('#grid').showCol("cb").trigger('reloadGrid');
This has a side effect of changing the grid width when toggled. It appears the cb column width is reserved when it is not hidden.
Basically I'm attempting to create a grid with an "edit/cancel" button to toggle the multiselect -- very similar to how the iPhone/iPad handles deleting multiple mail or text messages.
Thank you in advance.
I full agree with Justin that jqGrid don't support toggling of multiselect parameter dynamically. So +1 to his answer in any way. I agree, that the simplest and the only supported way to toggle multiselect parameter will be connected with re-initialize (re-creating) the grid.
So if you need to change the value of multiselect parameter of jqGrid you need first change multiselect parameter with respect of respect setGridParam and then re-creating the grid with respect of GridUnload method for example. See the demo from the answer.
Nevertheless I find your question very interesting (+1 for you too). It's a little sport task at least to try to implement the behavior.
Some remarks for the understanding the complexity of the problem. During filling of the body of the grid jqGrid code calculate positions of the cells based on the value of multiselect parameter (see setting of gi value here and usage it later, here for example). So if you will hide the column 'cb', which hold the checkboxes, the cell position will be calculated wrong. The grid will be filled correctly only if either the column 'cb' not exists at all or if you have multiselect: true. So you have to set multiselect: true before paging or sorting of the grid if the column 'cb' exist in the grid. Even for hidden column 'cb' you have to set multiselect to true. On the other side you have to set multiselect to the value which corresponds the real behavior which you need directly after filling of the grid (for example in the loadComplete).
I hope I express me clear inspite of my bad English. To be sure that all understand me correctly I repeat the same one more time. If you want try to toggle multiselect dynamically you have to do the following steps:
create grid in any way with multiselect: true to have 'cb' column
set multiselect: false and hide 'cb' column in the loadComplete if you want to have single select behavior
set multiselect: true always before refreshing the grid: before paging, sorting, filtering, reloading and so on.
I created the demo which seems to work. It has the button which can be used to toggle multiselect parameter:
In the demo I used the trick with subclassing (overwriting of the original event handle) of reloadGrid event which I described the old answer.
The most important parts of the code from the demo you will find below:
var events, originalReloadGrid, $grid = $("#list"), multiselect = false,
enableMultiselect = function (isEnable) {
$(this).jqGrid('setGridParam', {multiselect: (isEnable ? true : false)});
};
$grid.jqGrid({
// ... some parameters
multiselect: true,
onPaging: function () {
enableMultiselect.call(this, true);
},
onSortCol: function () {
enableMultiselect.call(this, true);
},
loadComplete: function () {
if (!multiselect) {
$(this).jqGrid('hideCol', 'cb');
} else {
$(this).jqGrid('showCol', 'cb');
}
enableMultiselect.call(this, multiselect);
}
});
$grid.jqGrid('navGrid', '#pager', {add: false, edit: false, del: false}, {}, {}, {},
{multipleSearch: true, multipleGroup: true, closeOnEscape: true, showQuery: true, closeAfterSearch: true});
events = $grid.data("events"); // read all events bound to
// Verify that one reloadGrid event hanler is set. It should be set
if (events && events.reloadGrid && events.reloadGrid.length === 1) {
originalReloadGrid = events.reloadGrid[0].handler; // save old
$grid.unbind('reloadGrid');
$grid.bind('reloadGrid', function (e, opts) {
enableMultiselect.call(this, true);
originalReloadGrid.call(this, e, opts);
});
}
$("#multi").button().click(function () {
var $this = $(this);
multiselect = $this.is(":checked");
$this.button("option", "label", multiselect ?
"To use single select click here" :
"To use multiselect click here");
enableMultiselect.call($grid[0], true);
$grid.trigger("reloadGrid");
});
UPDATED: In case of usage jQuery in version 1.8 or higher one have to change the line events = $grid.data("events"); to events = $._data($grid[0], "events");. One can find the modified demo here.
I really like what you are trying to do here, and think it would be a great enhancement for jqGrid, but unfortunately this is not officially supported. In the jqGrid documentation under Documentation | Options | multiselect you can see the Can be changed? column for multiselect reads:
No. see HOWTO
It would be nice if there was a link or more information about that HOWTO. Anyway, this is probably why you are running into all of the weird behavior. You may be able to work around it if you try hard enough - if so, please consider posting your solution here.
Alternatively, perhaps you could re-initialize the grid in place and change it from/to a multi-select grid? Not an ideal solution because the user will have to wait longer for the grid to be set up, but this is probably the quickest solution.
A simpler answer:
<input type="button" value="Multiselect" onclick="toggle_multiselect()">
<script>
function toggle_multiselect()
{
if ($('#list1 .cbox:visible').length > 0)
{
$('#list1').jqGrid('hideCol', 'cb');
jQuery('.jqgrow').click(function(){ jQuery('#list1').jqGrid('resetSelection'); this.checked = true; });
}
else
{
$('#list1').jqGrid('showCol', 'cb');
jQuery('.jqgrow').unbind('click');
}
}
</script>
Where list1 is from <table id="list1"></table>.
Good morning, I'm working on a jqGrid that have the multiselection active.
I need to limit the selection of the row only using the multisel box, not by clicking everywhere on the row.
Thats's because I need to do some action by clicking links on some cells and I won't alter the active multiselection.
I tried to set the multiboxonly property, but it's not what I need.
I didn't find anything else to customize this function of the grid.
You can control on which click the row will be selected with respect of your custom beforeSelectRow event handler. If the handler return true, the row will be selected. If you return false the row will be not selected.
The second parameter of beforeSelectRow is event object, e.target is the DOM element which was clicked. You can get the cell (<td>) in which the click done with $(e.target).closest('td'). Then you can use $.jgrid.getCellIndex to get the index of the cell insido of the row. The index in the colModel should point to the 'cb' column which contain the checkboxes. So the code could be the following:
beforeSelectRow: function (rowid, e) {
var $myGrid = $(this),
i = $.jgrid.getCellIndex($(e.target).closest('td')[0]),
cm = $myGrid.jqGrid('getGridParam', 'colModel');
return (cm[i].name === 'cb');
}
The corresponding demo you can see here.
I would like to suggest easier solution:
beforeSelectRow: function(rowid, e) {
return $(e.target).is('input[type=checkbox]');
},
When multiselect is set to true, clicking anywhere on a row selects that row; when multiboxonly is also set to true, the multiselection is done only when the checkbox is clicked.
So the answer would be:
multiboxonly: true
