Hi, I have a simple mobile site with a splitview and a main view. The split view has a list of categories and the main view displays a number of charts using d3.js.

The functionality works fine, but it is very slow when selecting a new category in the split view. Looking at a profile in chrome developer tools shows that 80% of the time is spent removing the children in the svg/g nodes of the d3 charts. Obviously there are a lot of these children as the charts have a lot of points and it seems that each one traverses the history list via a kendo observer pattern.

Is there a way to speed this up? Can I use a bit of java-script before the navigation happens to destroy the d3 svg elements without triggering all of the expensive kendo calls?

Thanks,

Ian

Hi,

 In my project I need to dynamically zoom in or out on a region or country.

e.g. I select a country or some countries of a region, and it gets a close-up of that country or region.

And when I deselect the countries, it zooms out. (Preferably animated).

I was wondering if you could let me know if Kendo GeoJSON Map has this functionality.

Thanks

$("#categories").kendoDropDownList({
    optionLabel: "Select category...",
    dataTextField: "CategoryName",
    dataValueField: "CategoryID",
    dataSource: {
        type: "odata",
        serverFiltering: true,
        transport: {
            read: "http://demos.kendoui.com/service/Northwind.svc/Categories"
        }
    },
    change: function () {
        var value = this.value();
        if (value) {
            productsDataSource.filter({
                field: "CategoryID",
                operator: "eq",
                value: parseInt(value)
            });
            products.enable();
        } else {
            products.enable(false);
        }
        products.select(0);
        orders.select(0);
        orders.enable(false); <--- BREAK HERE
    }
}); 

We have set up a simple line chart to show temperatures. It looks OK in the browser. When it is exported as an image, the degree signs are changed to the character code. See the attached image. Can anyone help with fixing this?

Thanks in advance,

I have a weird problem with the grid columns name when I use frozen columns. 

For example I have : column 1, column​ 2, column​ 3, column​4 and column 5 :

If I set the column 3 and column 5 to be frozen, the grid will have in the "k-grid-content-locked" the right content for column 3 and column 5. 

 In "k-grid-header-locked" I do NOT have the right columns name, I now have column 3 and column 1.  ( the problem is only for the name, the content of the grid has the right data displayed ) 

And for the unfrozen part, the content is displayed correctly, but where should be column 1, I now have column 5 .

Any help or idea will be appreciated.

Thank you!

Hello,

I am currently using a grid with virtual scrolling feature and I would like to add a line to the bottom of the grid. My problem is that even using GridInsertRowPosition.Bottom the line gets added at the bottom of the current "virtual" page. Also, after the lines gets added if I keep scrolling it exits edit mode and my grid will keep an empty line. 

Does anyone know a workaround for this? Even disabling scrolling on the grid during edition will be fine for me as long as the line gets added at the bottom.

Thanks in advance,

Marcos

Hi,

I have a problem with the behaviour of kendo components in face of a back button action.
Currently I have a page that changes a lot according with the user's choice (visibility of inputs and panels, values of inputs and result on grids). However, if the user navigate to another page and press back button on the browser, all these changes will be lost.

My question is, if there is a generic solution provided by Telerik for situations like this.

Thank you in advance.

For some reason the element that displays the down arrow on the kendo dropdownlist always has the inner text set to "select" so the letters "se" appear hovering over that dropdown button arrow. I'm not sure why this is happening, but the quickest and most global way for me was to get rid of it was to override the element's css and set the text color to transparant like so:

.k-dropdown-wrap > .k-select > span {
        color:transparent;
    }

Is there somewhere else that I can just remove the "select" inner text of this element? It really shouldn't be there.

I'm on the latest kendo ui.

Thanks,

Michael
