Description
How can I prevent page navigation while in edit mode of the Kendo UI Grid for jQuery?
Solution
The following examples demonstrate how to prevent page navigation when the Grid is in a batch or inline edit mode.
Batch Edit Mode
If the Grid is in edit mode and you do not make any changes, the page navigation and sorting are prevented. Otherwise, the new value is applied and a rebinding occurs.
<div id="example">
<div id="grid"></div>
<script>
$(document).ready(function () {
var crudServiceBaseUrl = "https://demos.telerik.com/service/v2/core",
dataSource = new kendo.data.DataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/Products"
},
update: {
url: crudServiceBaseUrl + "/Products/Update",
type: "POST",
contentType: "application/json"
},
destroy: {
url: crudServiceBaseUrl + "/Products/Destroy",
type: "POST",
contentType: "application/json"
},
create: {
url: crudServiceBaseUrl + "/Products/Create",
type: "POST",
contentType: "application/json"
},
parameterMap: function(options, operation) {
if (operation !== "read" && options.models) {
return kendo.stringify(options.models);
}
}
},
batch: true,
pageSize: 10,
schema: {
model: {
id: "ProductID",
fields: {
ProductID: { editable: false, nullable: true },
ProductName: { validation: { required: true } },
UnitPrice: { type: "number", validation: { required: true, min: 1} },
Discontinued: { type: "boolean" },
UnitsInStock: { type: "number", validation: { min: 0, required: true } }
}
}
},
requestStart: function(e) { //prevent grid navigation
if (preventAction) {
e.preventDefault();
}
}
});
var preventAction = false;
$("#grid").kendoGrid({
dataSource: dataSource,
navigatable: true,
pageable: true,
sortable: true,
height: 400,
toolbar: ["create", "save", "cancel"],
columns: [
"ProductName",
{ field: "UnitPrice", title: "Unit Price", format: "{0:c}", width: 120 },
{ field: "UnitsInStock", title: "Units In Stock", width: 120 },
{ field: "Discontinued", width: 120 },
{ command: "destroy", title: " ", width: 160 }],
editable: true,
edit: function() {
preventAction = true;
},
saveChanges: function() {
preventAction = false;
},
remove: function(e) {
if (preventAction) {
e.preventDefault();
e.row.show();
}
}
});
});
</script>
</div>Inline Edit Mode
If the Grid is in edit mode, paging and sorting are prevented.
<div id="example">
<div id="grid"></div>
<script>
$(document).ready(function () {
var crudServiceBaseUrl = "https://demos.telerik.com/service/v2/core",

},

url: crudServiceBaseUrl + "/Products/Destroy",
type: "POST",
contentType: "application/json"
},
create: {
url: crudServiceBaseUrl + "/Products/Create",
type: "POST",
contentType: "application/json"
},
parameterMap: function(options, operation) {
if (operation !== "read" && options.models) {
return kendo.stringify(options.models);
}
}
},
batch: true,

}
}
},
requestStart: function(e) { //prevent grid navigation
if (preventAction) {
e.preventDefault();
}
}
});
var preventAction = false;
$("#grid").kendoGrid({

{ command: ["edit", "destroy"], title: " ", width: 280 }],
editable: "inline",
edit: function() {
preventAction = true;
},
cancel: function() {
preventAction = false;
},
dataBound: function() {
preventAction = false;
}
});
});
