I am adding a click function to a column containing a button like so

            .Columns(columns =>
            {
                columns.Command(command =>
                {
                    command.Custom("customedit").Click("openScanLines").Text("").HtmlAttributes(new { title = "View Scan Details"});
                }).Width(75);
            })

We have an option to save the grid options to be loaded a later point.  So we use $("MyGrid").data("kendoGrid").getOptions() to get the options on the grid, Stringify it, and save it to a database  Then we pull that JSON string from the database and use $("MyGrid").data("kendoGrid").setOptions(options) to load them. The problem is the "Click" function is always missing from the $("MyGrid").data("kendoGrid").getOptions(), resulting in the Click function no longer working when the option are then set.  What's the deal?  How can I retain the click function for these columns?

Hello.

we are testing the kendo ComboBox as part of our widget system , in order to integrate with angular we included kendo.directive modules.

the Original issue i wanted to solve was how to disable the angular binding on key press up and down .

Our directives are ES6 Classes and we using the kendo combo box directive , the problem here is its seems that the combo-box create another input element on the page and don't copy other attributes we added like angular ng-keydown , when  i used the post compile method to find the new kendo input element then adding the missing properties and then $recompile the input the browser was unresponsive.

 Using the kendo auto-complete directive was good because it's don't replace the original object.

   _getElementHtml() {
                var mapper = this.mapper;
                var item = mapper ? 'item' : 'item.key';
                var mdId = this.$attrs.mdId + (this.listIndex ? "-" + this.listIndex : "");
                var html = [];

                html.push("<div class='idi-combo-box'>");
                html.push("<span ng-show='$this.filterText'>{{$this.filterText}}</span>");
                var kendoType = this.isServerAutoComplete() ? 'auto-complete' : 'combo-box';

                html.push("<input kendo-" + kendoType + " k-on-open='onOpen(kendoEvent)'  k-options='comboConfig'  k-data-source='comboList'  k-on-select='onSelection(kendoEvent)' ");
                html.push(" type='text' ng-show='!$this.filterText' id='" + mdId + "'");
                html.push(" ng-model='kendoInput' ");
                html.push(" tooltip-placement='bottom' ");
                html.push(" tooltip='{{$this.tooltip}}' ");
                html.push(" ng-keydown='$this._onKeyDown($event)'");
                html.push(" ng-keypress='$this._onKeyPress($event,$this)'");
                html.push(" ui-mask='{{::$this.mask}}'");

                html.push((this.$attrs.readOnly ? 'readonly="readonly" ' : ''));

                html.push("/>");
                html.push("</div>");

                return html.join('');
            }

thanks in advance,

                        e.preventDefault();
                    });
                }
            });
        }

I know this question has been asked many times but I was unable to find an answer, please help.
1. I need to update a value of the column "ProductName" that is not editable. I need to do it when I change (select) value in the dropdown Category

2. Keep the grid row in edit mode because I will change other fields in the row

3.  And then click Update button to update the grid row. Or cancel - to restore the original values in the row

Thank you!

Hi,

I would like to validate the dropdown list dataSource in resouces:

Hello,

Is it possible to change the series background color when it is below some value for example 0.

I am trying to achieve something like the attached image.

Using Angular 4.

Thank you!

Hi,

I've been working with the async upload and have a requirement to get the chunk version working as per the example at http://demos.telerik.com/kendo-ui/upload/chunkupload

I've got this working as per the demo and uploading to a local file system and I can step through the code to see how this works. However the file storage is SQL Server Filestream (which I have working with the standard async version) and it needs to handle much larger files (2+ GB) so I need to chunk upload to prevent it timing out and to give the user an indication of progress.

So, based on the demo included above I need to implement the SQL calls to upload the chunks in the foreach loop in the ChunkSave method but I'm not sure how to acheive this taking into account I need to wrap the chunks in a transaction so that I know if it's succeeded or failed. In addition I need to save additional values against each file so I'm not sure how I would acheive this (have a check in the foreach loop to see if these values have already been set maybe?).

I've not been able to find any examples using the Kendo control so if anyone could offer some advice or point me to some examples that would be very much appreciated.

Thanks,

Mark
