I've been struggling with deleting a record from a grid view all weekend. I could really use some assistance.

Below is my code:

01.var documentDataSource = new kendo.data.DataSource({
02.    transport: {
03.        read: { url: "/api/MedicalNecessityReviewAPI/GetDocumentsByAuthID", data: function () { return []; } }
04.        , create: { url: "/api/MedicalNecessityReviewAPI/AddDocument", data: function () { return []; } }
05.        , delete: {
06.            url: '/api/MedicalNecessityReviewAPI/DeleteMedReviewDocument'
07.            , data: { DocID: $("DocID").val(), UserID: $("UserID").val() }
08.            , dataType: "jsonp"
09.            , type: "GET"
10.        }
11.        , dataType: "jsonp"
12. 
13.        , parameterMap: function (options, operation) {
14.            if (operation !== "read" && options.models) {
15.                return { models: kendo.stringify(options.models) };
16.            }
17.        }
18.    }
19.    , serverPaging: false
20.    , serverSorting: false
21.    , serverFiltering: false
22.    , pageSize: 25
23.    , schema: {
24.        // total is returned in the "total" field of the response;
25.        total: "total"
26.        , data: "results"
27.    }
28.});
29. 
30.// search results kendo grid
31.$("#documentGrid").kendoGrid({
32.    autoBind: true
33.    , height: 400
34.    , sortable: false
35.    , pageable: { buttonCount: 5 }
36.    , filterable: false
37.    , selectable: false
38.    , columnMenu: false
39.    , noRecords: { template: kendo.template($("#EmptyGridMessage").html()) }
40.    , columns: [
41.        { field: "originalFilename", title: "File Name", width: "60%" }
42.        , { field: "lastUpdatedDate", title: "Uploaded Date", template: "#= kendo.toString(kendo.parseDate(lastUpdatedDate, 'yyyy-MM-dd'), 'MM/dd/yyyy') #" }
43.        //, { field: "docId", title: "DocId" }, { field: "authId", title: "AuthId" }, { field: "docData", title: "DocData" }, { field: "docExtension", title: "DocExtension" }, { field: "deleted", title: "Deleted" }, { field: "userId", title: "UserId" }
44.        , { command: ["Delete"], title: " ", width: "100px" }
45.    ]
46.    , dataSource: documentDataSource,
47.});

Any assistance would appreciated!

Here is where I am at this point:

01.// Documents datasource
02.var documentDataSource = new kendo.data.DataSource({
03.    transport: {
04.        read: { url: "/api/MedicalNecessityReviewAPI/GetDocumentsByAuthID", data: function () { return []; } }
05.        , create: { url: "/api/MedicalNecessityReviewAPI/AddDocument", data: function () { return []; } }
06.        , destroy: {
07.            url: '/api/MedicalNecessityReviewAPI/DeleteMedReviewDocument'
08.            , data: { DocID: $("#DocID").val(), UserID: $("#UserID").val() }
09.            , dataType: "jsonp"
10.            , type: "POST"
11.        }
12.        , dataType: "jsonp"
13.        , parameterMap: function (options, operation) {
14.            if (operation !== "read" && options.models) {
15.                return { models: kendo.stringify(options.models) };
16.            }
17.        }
18.    }
19.    , serverPaging: false
20.    , serverSorting: false
21.    , serverFiltering: false
22.    , pageSize: 25
23.    , schema: {
24.        total: "total"
25.        , data: "results"
26.        , model: {
27.            docId: { editable: false, nullable: true }
28.        }
29.    }
30.});
31. 
32.// documents kendo grid
33.$("#documentGrid").kendoGrid({
34.    autoBind: true
35.    , columns: [
36.        { field: "docID", hidden: true }
37.        , { field: "originalFilename", title: "File Name", width: "60%" }
38.        , { field: "lastUpdatedDate", title: "Uploaded Date", template: "#= kendo.toString(kendo.parseDate(lastUpdatedDate, 'yyyy-MM-dd'), 'MM/dd/yyyy') #" }
39.        , { field: "docId", title: "DocId" }//, { field: "authId", title: "AuthId" }, { field: "docData", title: "DocData" }, { field: "docExtension", title: "DocExtension" }, { field: "deleted", title: "Deleted" }, { field: "userId", title: "UserId" }
40.        , { command: "destroy" }
41.        , { template: "<a href='/api/MedicalNecessityReviewAPI/DocViewer?DocID=#= docId #'>View</a>", title: " " }
42.    ]
43.    , columnMenu: false
44.    , dataSource: documentDataSource//, schema: {model: {id: "id"}}
45.    , editable: "inline"
46.    , filterable: false
47.    , height: 400
48.    //, toolbar: ["edit", "save", "cancel"]
49.    //, messages: { commands: { save: "Save changes" } }
50.    , noRecords: { template: kendo.template($("#EmptyGridMessage").html()) }
51.    , pageable: { buttonCount: 5 }
52.    , selectable: false
53.    , sortable: false
54.});

 

It is now hitting my ADD API. I read somewhere else that the cause is because the ID is not being passed so it things it is a new record and wants to process under the "create". This to me is bad Telerik logic, but I'm STILL looking for a fix.

Here is where I am at this point. When I click "delete" it is asking me to verify that I want to delete and then it is calling the "create" and hitting the API. I read somewhere that this is because there is no data being passed. Below is the code at this point:

01.// Documents datasource
02.var documentDataSource = new kendo.data.DataSource({
03.    transport: {
04.        read: { url: "/api/MedicalNecessityReviewAPI/GetDocumentsByAuthID", data: function () { return []; } }
05.        , create: { url: "/api/MedicalNecessityReviewAPI/AddDocument", data: function () { return []; } }
06.        , destroy: {
07.            url: '/api/MedicalNecessityReviewAPI/DeleteMedReviewDocument'
08.            , data: { DocID: $("#DocID").val(), UserID: $("#UserID").val() }
09.            , dataType: "jsonp"
10.            , type: "POST"
11.        }
12.        , dataType: "jsonp"
13.        , parameterMap: function (options, operation) {
14.            if (operation !== "read" && options.models) {
15.                return { models: kendo.stringify(options.models) };
16.            }
17.        }
18.    }
19.    , serverPaging: false
20.    , serverSorting: false
21.    , serverFiltering: false
22.    , pageSize: 25
23.    , schema: {
24.        total: "total"
25.        , data: "results"
26.        , model: {
27.            docId: { editable: false, nullable: true }
28.        }
29.    }
30.});
31. 
32.// documents kendo grid
33.$("#documentGrid").kendoGrid({
34.    autoBind: true
35.    , columns: [
36.        { field: "docID", hidden: true }
37.        , { field: "originalFilename", title: "File Name", width: "60%" }
38.        , { field: "lastUpdatedDate", title: "Uploaded Date", template: "#= kendo.toString(kendo.parseDate(lastUpdatedDate, 'yyyy-MM-dd'), 'MM/dd/yyyy') #" }
39.        , { field: "docId", title: "DocId" }//, { field: "authId", title: "AuthId" }, { field: "docData", title: "DocData" }, { field: "docExtension", title: "DocExtension" }, { field: "deleted", title: "Deleted" }, { field: "userId", title: "UserId" }
40.        , { command: "destroy" }
41.        , { template: "<a href='/api/MedicalNecessityReviewAPI/DocViewer?DocID=#= docId #'>View</a>", title: " " }
42.    ]
43.    , columnMenu: false
44.    , dataSource: documentDataSource//, schema: {model: {id: "id"}}
45.    , editable: "inline"
46.    , filterable: false
47.    , height: 400
48.    //, toolbar: ["edit", "save", "cancel"]
49.    //, messages: { commands: { save: "Save changes" } }
50.    , noRecords: { template: kendo.template($("#EmptyGridMessage").html()) }
51.    , pageable: { buttonCount: 5 }
52.    , selectable: false
53.    , sortable: false
54.});

 

I could really use some assistance on this.

I know that no one has touched this yet, but just so others might find some help, I'm currently getting into the destroy API but I'm not getting my values passed though. Can someone help a brother out? Here is the code as it currently stands:

01.// Documents datasource
02.var documentDataSource = new kendo.data.DataSource({
03.    transport: {
04.        read: { url: "/api/MedicalNecessityReviewAPI/GetDocumentsByAuthID", data: function () { return []; } }
05.        , create: { url: "/api/MedicalNecessityReviewAPI/AddDocument", data: function () { return []; } }
06.        , destroy: {
07.            url: '/api/MedicalNecessityReviewAPI/DeleteMedReviewDocument'
08.            , data: { docID: 8, userID: 221317 }
09.            //, data: { DocID: $("#DocID").val(), UserID: $("#UserID").val() }
10.            , dataType: "jsonp"
11.            , type: "POST"
12.        }
13.        , dataType: "jsonp"
14.        , parameterMap: function (options, operation) {
15.            if (operation !== "read" && options.models) {
16.                return { models: kendo.stringify(options.models) };
17.            }
18.        }
19.    }
20.    , serverPaging: false
21.    , serverSorting: false
22.    , serverFiltering: false
23.    , pageSize: 25
24.    , schema: {
25.        total: "total"
26.        , data: "results"
27.        , model: {
28.            id: "docId"
29.            , fields: {
30.                docId: { editable: false, nullable: true }
31.                , originalFilename: { editable: true, nullable: true }
32.                , lastUpdatedDate: { editable: false, nullable: true }
33.            }
34.        }
35.    }
36.});
37. 
38.// documents kendo grid
39.$("#documentGrid").kendoGrid({
40.    autoBind: true
41.    , columns: [
42.        { field: "docID", hidden: true }
43.        , { field: "originalFilename", title: "File Name", width: "60%" }
44.        , { field: "lastUpdatedDate", title: "Uploaded Date", template: "#= kendo.toString(kendo.parseDate(lastUpdatedDate, 'yyyy-MM-dd'), 'MM/dd/yyyy') #" }
45.        , { field: "docId", title: "DocId" }//, { field: "authId", title: "AuthId" }, { field: "docData", title: "DocData" }, { field: "docExtension", title: "DocExtension" }, { field: "deleted", title: "Deleted" }, { field: "userId", title: "UserId" }
46.        , { command: "destroy" }
47.        , { template: "<a href='/api/MedicalNecessityReviewAPI/DocViewer?DocID=#= docId #'>View</a>", title: " " }
48.    ]
49.    , columnMenu: false
50.    , dataSource: documentDataSource//, schema: {model: {id: "id"}}
51.    , editable: "inline"
52.    , filterable: false
53.    , height: 400
54.    , noRecords: { template: kendo.template($("#EmptyGridMessage").html()) }

I really hope this helps someone else because not a single person helped me! Very disappointed.

So here is how we got it to work....

url: '@Url.Action("DeleteMedReviewDocument", "MedicalNecessityReviewAPI", new { docID=8, userID=221317 })'

 

I will post my completed code, so someone else can find sanity in my insanity, when I have the other things working correctly.

Hello Michael,

I'm sorry to hear that you are disappointed by the response time.

Please have in mind that our forums do not have a set response time as the support tickets(24 hours Mon-Fri):

http://www.telerik.com/purchase/support-plans/devtools

We usually try to respond to them within 2 business days, but we had a national holiday yesterday and we worked on a smaller capacity.

I hope that in the future we will provide faster response to the questions.

Still, if the issue is urgent I can suggest submitting a support ticket as the response time is usually twice as fast as the forum posts. 

Regards,
Stefan
