I want my Kendo grid's column read-only after bind. I have a dropdownlist in my page. Depending on the selected value of the dropdownlist I want to enable editing a cell in a row selected.
Does anyone have sample code?
It is possible to achieve the desired behavior like this:
use the edit event of the Grid, check the DropDownList value() and if editing should be prevented, execute the Grid's closeCell() method to exit edit mode. If the user is trying to add a new item to the Grid (e.model.isNew()), you will also need to remove() this new item with the respective dataSource method.
use the change event of the DropDownList to hide the CRUD-related buttons in the Grid with custom CSS styles.
Another possible option is to recreate and rebind the Grid with the correct editing settings via setOptions every time the dropDownList value changes.
The example below uses the first approach described above. You can modify it, so that not only the Delete buttons are toggled, but also Add New Record.

I have following code using free-jqgrid. It loads correctly for the first time (Status is “Active” and Partner? is “Yes”). But when I do a sort or search, the values become incorrect(Status is “Retired” and Partner? is “No”).
Why the formatters are giving incorrect values? How to fix this?

UPDATE
Thanks to Oleg, working demo can be found here - Fiddle . It uses "/echo/json/" service of JSFiddle to get data from server.
It uses sorttype and additionalProperties. This can be rewritten without additionalProperties - I need to do it when I get a chance to revisit this.
The problem seems be very easy. The data returned from the server contains properties Practice, ProviderID, IsActive and IsPartner. The properties are available in rowObject during initial loading. You use additionally loadonce: true option. Thus free jqGrid will try to save some data locally, but which one? jqGrid saves by default the properties which corresponds the names of columns: Practice, ProviderID, PartnerStatusText and ActiveStatusText, but jqGrid have no information that other properties IsActive and IsPartner need be saved too.
You can solve the problem in two alternative ways:
you rename the column names PartnerStatusText and ActiveStatusText to IsActive and IsPartner.
you add the option additionalProperties: ["IsActive", "IsPartner"] to inform jqGrid to read and save locally additional properties.
Moreover, I'd recommend you to use options.rowData instead of rowObject inside of custom formatter. You can skip the 3-d parameter and to use formatter: function (cellvalue, options) {...}.
The final remark: the current code of the custom formatter is very easy. You need to replace some input values (true and false) to another text. One can use formatter: "select" for the case:
colModel: [
{ name: "Practice" },
{ name: "ProviderID" },
{
name: "IsPartner",
width: 70,
formatter: "select",
formatoptions: { value: "false:No;true:Yes" }
},
{
name: "IsActive",
width: 70,
formatter: "select",
formatoptions: { value: "false:Retired;true:Active" }
}
],

I'm new to jqgrid and jquery, can someone please help me in disabling the cell when the date is null or empty or undefined?
Actually the json for some (rows,col) date data is there and for some it is not there.
I want to disable the cell in the row for which Date data is not available.

There are exist alternative fork of jqGrid: free jqGrid, which I develop since more as one year. It has the functionality, where one can define editable property of colModel as function, which can return true or false based on the cell or the row content. See the wiki article for more details.
Check if this How to disable editing for soe cells in row editing of JQGrid
helps, it seen it is a similar thing, You just need to add into your logic.
List item
I have a page which loads a kendo TreeList by pressing a button. The data is for the moment statically defined in a variable where it stays as a basis for the Kendo TreeList datasource.
I have a datasource definition which I mostly copied from Telerik Website.
I have a treelist with a couple of requirements in terms of CRUD.
level1 - nothing
level2 - add new childnodes only
level3 - edit and delete
Edit should be doubleclick on a level3 item
CRUD command buttons need to be icon-only (no text in the buttons)
I could not achieve this with the buildin CRUD controls unfortunately so I used a Template column where the buttons are placed based on their "Type" field.
Now this has worked but after some changes which I can't undo somehow the add function does not work anymore. It works but new childnode is only visible after a edit ordelete of another node. (as if the change event is not triggered during add). The Add button in the treeList calls a function addProduct where at the end I try to pushCreate directly to the datasource. However the Transport.create is never invoked. It only gets invoked after another Crud action triggers it
Can anybody see what's wrong and couldn't this all be achieve with much easier approach?

I found the answer !!!
The datasource pagesize is set to 10 and the TreeList was set to paging: false. In all my tests I started with sample data of 10 nodes. All the time I was adding an 11th and 12th record which wasn't showing up until I deleted another node...
Do these things only happen to me?
Although I have tried several times, I could not solve trying many method.
Shortly this is the thing what I want to do : only get modified or new rows as an object or JSON string.
You should use set for changing the content of a record. Then, getting the records modified is just iterating through datasource.data() array and checking which items have dirty set to true.
var data = grid.dataSource.data();
var dirty = $.grep(data, function(item) {
return item.dirty
});
// Dirty array contains those elements modified
console.log("dirty", dirty);
The following snippet shows both that changing the data programmatically or via Grid built-in incell edition is compatible with this approach.

var crudServiceBaseUrl = "http://demos.telerik.com/kendo-ui/service",

I am trying to bind kendo UI datagrid to my azure backend mobile services table (SASA) following this tutorial.
http://ignaciofuentes.com/archive/2014/01/20/zumo-kendo/
but unfortunately for some reasons it is not working. I have tried updating the mobile services javascript sdk from 1.0.0 to 1.1.5 still with no luck.
Here is my code.. can anyone point out what am I doing wrong.. the service is returning proper JSON..

$(document).ready(function() {
var client = new WindowsAzure.MobileServiceClient("MY SERVICE URL", "MY API KEY");
var table = client.getTable("sasa");
var dataSource = new kendo.data.DataSource({
transport: {
read: function (options) {
table.includeTotalCount() //necessary for grid to paginate
.read()
.done(options.success);
},
update: function (options) {
table.update(options.data)
.done(options.success);
},
create: function (options) {
var item = options.data;
delete item.id; //ZUMO doesnt allow you to set your own ID. It gets auto generated.
table.insert(item)
.done(options.success);
},
destroy: function (options) {
table.del(options.data)
.done(options.success);
}
},
pageSize: 10,
schema: {
total: "totalCount",
model: {
id: "id",
fields: {
id: { type: "number" },
name: { type: "string" },
developer: { type: "string" },
}
}
}});
$("#grid").kendoGrid({
pageable: true,
dataSource: dataSource,
columns: [
"name",
"developer", {
command: [{
name: "edit",
text: "Edit"
}, {
name: "destroy",
text: "Delete"
}]
}],
toolbar: [{
name: "create"
}],
editable: "inline"
});
});
</script>
</div>
</body>
</html>
On a test I did a while back using a kendo datasource and a windows azure mobile service, my dataSource CRUD methods were a bit different.
create: function(options) {
delete options.data.id;
client.getTable("Customer").insert(options.data).done(function(data) {
options.success(data);
});
},
read: function(options) {
client.getTable("Customer").read().done(function(data) {
options.success(data);
});
},
update: function(options) {
client.getTable("Customer").update(options.data).done(function(data) {
options.success(data);
});
},
destroy: function(options) {
client.getTable("Customer").del(options.data).done(function(data) {
options.success(data);
});
}
And it worked properly. Perhaps try changing the .done(options.success); to
.done(function(data) {
options.success(data);
});
And see if it works ?
--edit I rebuilt my MobileService I used to test with and dug up the code, it still works properly. Here is the sample at jsbin http://jsbin.com/jirexo/2/edit
