Hi,

I have a series that is based on the following:

x (horizontal) axis:  12 months for current year.

y (vertical) axis:  inches of rain that fell in that month (units is inch)

 Now, I have my series data and all charts well. 

The one thing I also have is the starting point (pt A) and end point (pt B) for a simple linear regression line that I need to draw a straight line from pt A to pt B to show the trend over time.  Point A will reside in the first column (January) and point B will reside in the last column (December).  ( I am using canvas for the charting).

I would prefer to do this with the 2 end points I already have as opposed to determining each point for each month to create a different chart series based on these points where due to rounding et al - which could result in this new curve not being perfectly perfectly straight.

So I guess in short, is it possible to draw a straight line from month 1 to month 12 on a chart knowing only 2 points where the line would be inserted via svg et al at dynamically?

 Thanks,

 Rene.

Hi, 

I am using the Kendo Grid with the datasource but for some reason the grid doesn't render properly during Visual Studio's Debugging option. 

However, when I go and publish it to an IIS server, it will load up everything just fine.

 I noticed that during the localhost instance, I am getting an "Uncaught ReferenceError: Kendo is not defined.

 Is there somethign I am missing that is causing this as published, the grid works fine, but using the localhost instance through Visual Studio, the grid is showing up with errors?

I've got a Grid with a cell that has an editor template that contains an auto complete object.

When the edit for this cell is complete, the grid displays the data as "[object Object]".

If the user goes back and uses the auto complete to select a field, the correct string is passed back to the Grid from the Editor template, however the auto complete functionality becomes buggy. (no javascript errors are thrown)

Hi

We are using the grid getOptions/setOptions to persist the users filters, column settings etc to a cookie

An issue we now have is it seems to persist everything including the datasource urls for read/update. This is an issue for us as we use custom MVC routes which look something like this: /jobs/1234/deliverable so the id is embedded into the url. When this is persisted the grid ends up querying data for a previously used Id.

What is the best way to prevent persisting the datasource url information and always use the URL as defined in the html page?

We have managed to get it working by doing this:

Is there a better way to do this and is there anything else we should be preventing (e.g. update, delete) if this were to be a generic function for the entire project?

One other strange we noticed is the object stored from getOptions is a slightly different structure to that directly on the grid.

E.g. the Grid has dataSource.transport.options.read but the getOptions stores dataSource.transport.read

Thanks

Hi,

I have a few columns defined that I don't want the user to change.

When they click a button, it calls a service which returns data. I want to update the columns with this data.

The problem is, if they're set to read-only, I can't change them, and the databound event never fires

.Events(e => e.DataBound("dataBound")) 

.DataSource(dataSource => dataSource
.Ajax()
.Batch(true)
.Events(events => events.Error("error_handler"))
.Model(model =>
{
model.Id(p => p.SnapshotDefinitionID);
                //model.Field(p => p.NextSnapshotQueueID).Editable(false);
                //model.Field(p => p.NextSnapshotQueueTime).Editable(false);
                model.Field(p => p.LastSnapshotQueueID).Editable(false);
                model.Field(p => p.LastSnapshotQueueTime).Editable(false);

                model.Field(p => p.NextScheduleID).Editable(false);
                model.Field(p => p.NextScheduleTime).Editable(false);
                model.Field(p => p.LastScheduleID).Editable(false);
                model.Field(p => p.LastScheduleTime).Editable(false);

model.Field(p => p.SnapshotQueueCount).Editable(false);
model.Field(p => p.ScheduleCount).Editable(false);


//model.Field(p => p.Client).DefaultValue(
//    ViewData["defaultClient"] as DropDownListViewModel);
})
.Create(update => update.Action("BulkCreate", "SnapshotDefinition"))
.Read(read => read.Action("BulkRead", "SnapshotDefinition", new { clientId = @Request["ClientID"], snapshotDefinitionID = @Request["SnapshotDefinitionID"] }))
.Update(update => update.Action("BulkUpdate", "SnapshotDefinition"))
.Destroy(update => update.Action("BulkDestroy", "SnapshotDefinition"))

 
    function createSnapshot(e) {
        window.grid = $("#grid").data("kendoGrid");
        window.dataItem = window.grid.dataItem($(event.srcElement).closest("tr"));
        //alert(grid);

        if (dataItem.NextSnapshotQueueID && dataItem.NextSnapshotQueueID != 0 && dataItem.CurrentPercentageComplete == 0) {
            $.ajax({
                url: "/SnapshotQueue/CancelSnapshotQueue",
                //send current record ID to the server
                data: { SnapshotQueueID: dataItem.NextSnapshotQueueID },
                success: function (data) {
                    //update the current dataItem with the received data from the server

                    window.dataItem.set('NextSnapshotQueueID', '0');
                    window.dataItem.set('NextSnapshotQueueTime', '');
                    
                }
            });
        } else {
            if (dataItem.CurrentPercentageComplete == 0) {
                $.ajax({
                    url: "/SnapshotDefinition/CreateSnapshot",
                    //send current record ID to the server
                    data: { SnapshotDefinitionID: window.dataItem.SnapshotDefinitionID },
                    success: function (data) {
                        //update the current dataItem with the received data from the server

                        if (data['NextSnapshotQueueID']) {
                            window.dataItem.set('NextSnapshotQueueID', data['NextSnapshotQueueID']);
                            window.dataItem.set('NextSnapshotQueueTime', kendo.parseDate(data['NextSnapshotQueueTime']));
                        }
                        //for (var property in data) {
                        //    dataItem.set(property, data[property]);
                        //}
                    }
                });
            }
        }

    }


    function dataBound(e) {
        var rows = this.table.find("tr[role='row']");

        for (var i = 0; i < rows.length; i++) {
            var model = this.dataItem(rows[i]);
            if (model.NextSnapshotQueueID != 0 && model.CurrentPercentageComplete == 0) {
                $(rows[i]).find(".k-grid-CreateSnapshot").contents().last()[0].textContent = 'Cancel Queued Snapshot';
            }
            if (model.NextSnapshotQueueID != 0 && model.CurrentPercentageComplete != 0) {
                $(rows[i]).find(".k-grid-CreateSnapshot").contents().last()[0].textContent = '';
                $(rows[i]).find(".k-grid-CreateSnapshot").width(100);
                $(rows[i]).find(".k-grid-CreateSnapshot").removeClass('k-button');
                $(rows[i]).find(".k-grid-CreateSnapshot").kendoProgressBar({
                    value: model.CurrentPercentageComplete,
                    max: 100
                });
            }
        }
    }

When a user selects a row in my grid, I can get the dataItem from a button click as follows:

$("#viewApplicationBtn").on("click", function () {
        var grid = $("#Grid").data("kendoGrid");
        var gridData = grid.dataItem(grid.select());

What I would like to do from this point is post this back to my controller, let the MVC model binder map to my ViewModel, and then redirect to another view which is of that model type.

The roadblock I'm facing is that an ajax post won't accomplish this and I can't pass the properties in a Url.Action helper because there are too many

here is my ajax:

$.ajax({
            type: "POST",
            url: "@Url.Action("ValidateModel")",
            datatype: "json",
            contentType: "application/json",
            data: JSON.stringify(gridData),
            success: function(data) {
                window.location.href = @Url.Action("Details", "GridController");
            },
            error: function(data) {
                console.log("post failed");
            }
        });

So how can I use my grid selection to post to another view with a Model?
