I have a dropdownlist on the Add Record template on a detail Grid.  I need to pass details of the parent model with the read method of the dropdownlist datasource.  Here is my code:

  $scope.detailGridOptions = function (dataItem) {
      return {
          dataSource: {
              type: 'aspnetmvc-ajax',
              transport: {
                  read: "/SSQV4/SSQV5/Operator/GetTaggedContractorsByMajor"
                  ,
                  create: "/SSQV4/SSQV5/Operator/AddContractorToTag"
              },
              serverPaging: true,
              serverSorting: true,
              serverFiltering: true,
              schema: {
                  data: "Data",
                  total: "Total",
                  model: {
                    id: "CompanyID",
                    fields: {
                        CompanyID: { editable: true, nullable: false, type: "number" },
                        TagID: { editable: true, nullable: true, type: "number" },
                        vchCompanyName: { editable: false, nullable: false, type: "string"},
                        Date: { editable: false, nullable: false, type: "date" },
                        AddedBy: { editable: false, nullable: false, type: "string" }
              }
          }
              },
              pageSize: 5,
              filter: { field: "TagID", operator: "eq", value: dataItem.TagID }
          },
          scrollable: false,
          sortable: true,
          pageable: true,
          editable: "popup",
          edit: function (e) {
              var grid = $scope.tagsGrid;
              var uid = e.model.uid;
              var selector = kendo.format("tr[data-uid='{0}']", uid);
              var currentGridElement = $(selector).closest("[data-role=grid]");
              var parentRow = currentGridElement.closest(".k-detail-row").prev();
              var parentModel = grid.dataItem(parentRow);
              e.model.TagID = parentModel.TagID;
          },
          toolbar: ["create"],
          columns: [
          {
              field: "TagID"
            , hidden: true
          }
          ,
              {
                  field: "CompanyID",
                  title: "CompanyID"
                  , editor: companyDropDownEditor
              }
          ,
            {
                field: "vchCompanyName",
                title: "Company Name"
            }
            ,
              {
                  field: "Date",
                  title: "Date Added"
              }
              ,
              {
                  field: "AddedBy",
                  title: "Added By"
              }
          ]

      };
  };

  function companyDropDownEditor(container, options) {
      var grid = $scope.tagsGrid;
      var uid = options.model.uid;
      var selector = kendo.format("tr[data-uid='{0}']", uid);
      var currentGridElement = $(selector).closest("[data-role=grid]");
      var parentRow = currentGridElement.closest(".k-detail-row").prev();
      var parentModel = grid.dataItem(parentRow);
     
      

      $('<input required name="' + options.field + '"/>')
          .appendTo(container)
          .kendoDropDownList({
              autoBind: true,
              dataTextField: "CompanyName",
              dataValueField: "CompanyID",
              template:  "#=CompanyName#",
              dataSource: {
                  transport: {
                      read: "/SSQV4/SSQV5/Operator/GetUntaggedContractors",
                      data: {contractor: parentModel}
                  }
              }
              
          });
  }

Here is my MVC Action Method:

        public async Task<ActionResult> GetUntaggedContractors([DataSourceRequest] DataSourceRequest request,
            ContractorTagModel contractor)
        {
            majorId = UserInfo.intMajorID;
            var tagId = contractor.TagID;
            var contractors = await CompanyClient.GetUntaggedContractors(majorId, tagId);
            return Json(contractors, JsonRequestBehavior.AllowGet);
        }

When the Action Method is hit, the model is always empty.  I actually don't need the entire model, just the TagID, but I don't get anything but zeros in my model.  Any assistance is greatly appreciated!

 

Hi there guys, its me again. I have a tab-strip that calls a details page for a Person,House, and Car tab. These tabs display the data just fine. On each detail page, i have an edit button, when i click the edit button, right now, when i click the edit button,  i am re-directed to the edit page outside of the tab-strip which isn't what i want. How do i make it load up the edit page within the tab-strip and ultimately when i click save, how to i make  re-load the details page again within the tab-strip.

Index.cshtml- from the InfoController

 

Here is the InfoController.cs

 

Here is my Detail.cshtml - for the Person tab

 

And here is my Edit.cshtml for  the - Person tab

 

And Finally here is my PersonController.cs

 

I have attached images to help explain what i am seeing. Thanks for your help.

I have a form that has a couple of textboxes and the Kendo Upload control.  I also haven event on the submit button to ensure the textboxes have appropriate values in it, but how do I validate the upload?  Or IOW, how do I validate the user has actually selected a file before submitting the form?

I have a treelist bound to server data that i need to open to the same branch after refresh.

The refresh is done with a separate button that reloads the data from the database, and returns the path to the last selected tree node as list of the node's id's. Problem is that the tree is set to load data only when needed, so the loop this function runs attempting to expand the tree works too fast, and tries to expand nodes that the tree hasn't loaded yet.

Function code is following

The above works if the user dismisses the "opening tree" alert after the tree has loaded and opened the tree branch, but is it possible to make the function wait for the data to be loaded without manual control, or is there some other way to perform this function?

Hi,

I have a RadGrid in Edit Mode, with a checkbox that when it is checked, a DropDownList's Enabled state should be True. When the checkbox is unchecked, the DropDownList's Enabled state should be False. Unfortunately I cannot get the Enabled state set after using the following code:

 

 

 

I have a tab strip with three tabs, each containing a text box  and a save button, for users to enter some comments in.
Depending on the selection of a drop-down list, I need to hide one tab, and rename another one.

The best I can do is disable one tab.  I don't want to have to destroy and recreate the tabs, as I'm already loading data via ajax into each of the text boxes, on the drop-down list change.

How can I change a tab's title, and hide / unhide one.
I can disable one tab, but not hide it

Is this possible? I can't see anything in the API about this.

Hi,

Im launching a modal from a kendo grid button, using kendo window.

It opens and displays its content fine, but when I click close, the overlay over the parent remains and I cant do anything.

Heres my code -

Parent View where grid exists -

Script -

 

 

The view that displays in the modal is a partial view -

 

 

Any ideas on why the overlay remains when the modal closes?

Thanks.

If you look at the filters on http://demos.telerik.com/aspnet-mvc/grid/filter-menu-customization you will see the attached image. The text at the top of the filter popup says "Show items with value that:" This string's contents can be changed with:

.Messages(m => m.Info("my text"))

and that works as expected. What I can't understand is why the Filter button shows the same text as a tool tip if you hover on it. Worse yet, the Clear button shows the exact same text, which makes no sense. Hover on the Filter and Clear buttons on that page and you will see what I'm talking about.

Is there a way to set the text at the top of the popup without also setting the Filter and Clear button tool tips?

Or is there a way to set the tool tips to say something else?

Thanks.

This is strange because I am pretty sure this had been working in the past...

Have a ComboBox using ComboBoxFor with a model property.  Pretty basic config with server filtering.

On form the model property is being set to the DataTextField of the ComboBox. Shouldn't it be the DataValueField? The value is being set correctly when I add an alert to the onSelect event of the ComboBox and output the Value field.

I developed an Editor template which is displayed as a modal/pop-up form used to update row data
values on a grid.  I need to show/hide sections on the form based on the values set on the
dropdownlist.  The show/hide functionality works when the dropdownlist value changes. 

However,  I need to set which sections/panels are hidden when the form initially loads before the page is rendered.
I’ve tried retrieving the selected option value in the $(document).ready() function as illustrated in the
source code I’ve included. However, the value/text is either null or undefined when the ready function is invoked.
After the  $(document).ready() function execution completes,  dropdownlist fields display the data from the grid correctly.

How would I go about retrieving the initial value of the dropdown lists before form is rendered in order to process the logic needed to
show / hide the appropriate sections on the form?
