Does anyone have any sample code how to integrate image copy/paste with the Upload component?  Or would we just use a different component entirely (jQuery plugin) to support this feature?  We want to allow a user the option to paste an image from clipboard in addition to the other methods like file drag drop and selecting files/directories.

Thanks!

Hi

I have a grid where I get my data from the server.
In my pager Im showing this page sizes [25,50,100,"All"] which works fine. 

But now,when we have more than 10000 items in the totalResults I want to remove the "All" option. 
How can I change the pagesizes of the pager?

But I only want to change the selectbox without reloading (and fetching the data) the grid again.

I tried it in the Databound event like this

dataBound(e) {
   var grid = e.sender;
   var pageSizes = self.totalResults < 10000
                ? [self.gridPageSize, self.gridPageSize * 2, self.gridPageSize * 4, "all"]
                : [self.gridPageSize, self.gridPageSize * 2, self.gridPageSize * 4];

   grid.setOptions({ pageable: { pageSizes: pageSizes  } });

}

This leads me in a endless loop because the setOptions refrehes the grid.
Because the query can take some time, I dont want to load the data again.
I also played around with hidding the "ALL" option via css. But this, I also didn't get to work.

Than I tried to bind the options and change them directly like this.

    <div kendo-grid="grid" id="grid"
         k-options="mainGridOptions"
         k-rebind="mainGridOptions">
    </div>

self.mainGridOptions.pageable.pageSizes = pageSizes;
This works, but also does a refresh of the grid (and does another api call to the backoffice)

So, is there a way to change the pagesizes without refreshing the data of the grid.

Thanks.

Here is a link to reproduce an issue - https://dojo.telerik.com/@WA_PMak/uNEVisOT

inPlaceSort property setted to true brakes sort if it used together with filter in virtualization mode.
Steps to reproduce:

1. Set inPlaceSort=true, turn virtualiztion on.
2. Set filter of City column to "not equals to "qwerty".
3. Set First Name column order to asc.
4. Set Last Name column order to asc.
5. Scroll till grid loads next virtual page.
   
   Actual result: setted sorting and filtering brakes - data in unordered state
   Expected result: data keeps it order and filtering states. 

Hi.

I change the type of the input element to "number" from "text" because I want to display a numeric input keyboard with a smart device.

However, I noticed that I can not enter negative values more than 10 digits from the PC keyboard..

Can I enter a negative value?

I have a spreadsheet with a remote datasource, linked via the .read() function of the datasource.

I would like to add a formula to a specific cell on each row (over 5000 rows).The cell config is called "pageWeightValue". The datasource.data() method is an array on my objects, where each object has an attribute called pageWeightValue. Is there a way to set the value in the array to the formula. The column is set to type string, but the formula is not applied as a formula, but rather an actual string. Ie for each record in my array I do object.pageWeightValue = '=sum(A1:A4)' (the letter changes dependant on the row number). However in the cell I set the exact string, rather than the formula result.

Thanks!

I have a ASP.NET WebAPI service that returns a list of resources 50 at a time.  I have over a million records and cannot return all rows at once.  I would like to use the Kendo UI Grid (latest jQuery version) with virtual scrolling enabled.  I do not want people to have to hit next, next, next in order to see more data. 

I am stuck at how to implement this.  Is there an example of virtual scrolling with a server-paged datasource?  I believe I need a custom transport method and could really use an example to get me started.

Thank you,
Alex

Hello,
I use the following code to format the text if it is too long.

function createShape(options) {
    var shapeOptions = {
        editable: false,
        selectable: false,
        id: options.id,
        x: options.positionX || 0,
        y: options.positionY || 0,
        width: options.width || 200,
        height: options.height || 50,
        type: options.type,
        path: options.path || undefined,
        content: {
            text: options.textData || undefined,
            color: '#fff',
            fontSize: 15
        },
        fill: options.fillColor || '#0088CC',
        stroke: options.strokeColor || '#0088CC',
    };
   
    var shape = new kendo.dataviz.diagram.Shape(shapeOptions);
    var texts = options.textData.split(" ");
    for (var i = 0; i < texts.length; i++) {
        shape.visual.append(new kendo.dataviz.diagram.TextBlock({
            text: texts[i],
            color: "#fff"
        }));
    }
    shape.visual.reflow();
    
    return shape;
}

I would like to be able to use the method : reflow() afterwards; so that the words of the text place this correctly.  Can you tell me how to do that? Thank you for your help.

Hello,

I have a treeview that implements load on demand which is working fine for me. I use the treeview.append() method to append children of the given node.

But strangely, in some scenarios the checkbox behaviour is not proper. I have set checkChildren: true in my code.

A scenario to reproduce this is,

check a node in the root level of the tree.

Expand two levels down in the tree.

Uncheck the root level node.

Expand some other node at level two belonging to the root level node unchecked in previous step,

the nodes still seem to be checked even though their parent node is unchecked.

Any help in this regard would be higly appreciated.

Thanks,

Niranjan
