Allow customisation of the bool filter in grids.  I.E. implement the UI property that works for other non-checked columns.  The current filter is too wide, does not allow fontawesome characters, etc.

I was working with Sencha ExtJS and they have to option to make components "stateful" (http://docs.sencha.com/extjs/6.2.0/classic/Ext.state.Provider.html). This will safe user modified settings in browser (defaults to cookie but you can provide your own implementation).

Example (for grid):
* we specify width=100 for first colum
* we allow users to resize columns
* If a users resizes a column the new width will be stored in state
* ... if the user later opens the page again, values from state will overwrite "defaults" from code.

If we use this for column width, visibility and order we've a perfect customizable grid view.

It would be nice to have the possibility of using own template for the exported data, as some data may be obtained from own functions.
Something like this:
            columns: [
                {
                    field: "ProductName",
                    title: "Product Name",
                    aggregates: ["count"],
                    footerTemplate: "Total Count: #=count#",
                    groupFooterTemplate: "Count: #=count#"
                },
                {
                    field: "UnitPrice",
                    title: "Unit Price",
                    template: '<div style="text-align: right; font-weight: bold;">#= kendo.toString(UnitPrice, "n2") #</div>',
                    exportTemplate: '#= kendo.toString(UnitPrice, "n4") #',
                    aggregates: ["sum"]
                }
            ]

When scrolling data in a grid using the virtualization scrolling option, the query to fetch the next section of data will occur twice. It does not happen for every query, but it does happen all the time regardless of scrolling fast or slow.

We are needing the virtual scrolling to work for our project and also need the detail rows working. The explaination of the problem was described on the forums here:
http://www.kendoui.com/forums/ui/grid/hidden-detail-row-when-using-detail-template-and-virtual-scrolling.aspx

When you configure a grid date-column with a custom format, the value configured in 'format' is parsed using JSON.parse. This requires the use of double quotes for both keys and values.

var a = "{0:dd/MMMM/yyyy}";    // example from docs
JSON.parse(a);    // SyntaxError: JSON.parse: expected property name or '}'

var b = '{"0":"dd-MM-yyyy"}';
JSON.parse(b);    // jey! 

However, if you use the latter, the generated template goes fubar with the message:

"Invalid template:' ... <td>${kendo.format("{"0":"dd-MM-yyyy"\}",theDataField)}</td> ... "

This makes sense when you look at the quote mismatch..

When I bind a change event to the grid it will fire each time I click on the row, even if it is the same row.  So the selected row is not actually changing, but the event keeps firing anyways.  The same thing happens if I programmatically select the row using the select method.

I would rather the change event only fire when when the selection has actually changed rather than on every re-selection.

Otherwise, you might as well call the event "onSelect" rather than "change".

For extra points, it would be cool if the event received a reference to the previous row that was selected.

Add the ability to display the Show/Hide Column menu by right clicking the Column Header instead of going through the "Column Menu".

It would also be nice if you could access the Filter directly instead of going through the "Column Menu"

The current Column Menu unnecessarily hides functionality in a menu  that should be more easily accessible.

It would be great to have support for all wildcards while filtering.

Have a simple Boolean option that tells the filter to either use or ignore the time portion of a filter on type 'date'. Filtering 'exactly' on date and time is almost useless, whereas filtering on a day provides useful information.

Currently, Kendo Grid has a "column.values" option that accepts an array of key/value pairs.  These values are used to render human-readable text for fields that are foreign keys.  Depending on how the grid is used, this array of "available values" could be dynamic.  Currently, there is no way to update these arrays without calling "setOptions" manually with the new, correct column definitions.

To fix this, Kendo Grid should track changes to the "column.value" array (via some sort of observable or something - I'm not sure exactly how things work under the hood).  Alternatively, "column.values" could also accept a function.  This function would return the up-to-date values array (Kendo Grid would have to be smart enough to execute the function whenever necessary).

Note:  this is the same functionality that has been requested by http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback/suggestions/13355043-kendogrid-allow-updating-columns-values-array-nee

showColumn() and hideColumn() is great, but it would be nice if we could pass multiple columns to the methods (maybe as an array).

It's extremely slow if I create a loop and call show/hideColumns(x) multiple times.

This would ideally apply to any grid component (Kendo Grid and TreeList).

My users ask for this in almost every application.  When a grid is grouped, the users want to see the groups in an order that indicates some ranking by an aggregate value. For example, If SALES-DETAIL table is grouped by SALESPERSON, the default alphabetic order of the groups might be AMELIA, BARBARA, CARLOS, DAVID, HARRY, THOMAS, ZELDA. But users want to see the groupings in descending order by the salesperson's TotalSales, which might be HARRY, ZELDA, AMELIA, THOMAS...etc. So we need a way to specify a custom-group-sortorder. And to be perfectly clear, that is the sequence of groups with respect to each other, not the order of detail data inside the group. The detail records might be sorted chronologically by SalesDate regardless of the order of the group relative to each other. In SQL the equivalent would be  ... GROUP BY SALESPERSON ORDER BY SUM(TotalSales) DESC(ending). This feature would work hand-in-glove with another requested feature, showing the group footer when the group is collapsed.

Introduce an expression builder for specifying filtering the grid by custom rules. Similar to the RadGrid for Silverlight: http://demos.telerik.com/silverlight/#ExpressionEditor/FilteringGridView

Current filter control for a date column only shows a date picker, if the data that's bound to the column also contains the time part then the filters don't work properly. Adding a date time picker would solve the problem.

We want events for expand/collapse groups in Grid, similar to the existing events for details.
This events will helps us for personalize some funcionalitys.

Thanks.

It would be nice to be able to configure the grid in a way that when I collapse a group, the lines it was occupying are then filled up by the results from the following pages.

Kendo Grid currently only minimizes the results of the current page. It ignores the pageSize config we have set, not bringing more items to occupy the number of lines we have configured.

Here are some screenshots I took from the DevExpress grid. There you can see that the column year is grouped and initially the years 90 and 91 are expanded. When I collapse the year 90, the results from the year 91 fill up the space the other group was not using anymore.

Please provide functionality for transposing a grid out of the box. My team has many members who need this functionality. For the moment, everone is transposing the data and then binding it to the grid. Please let me know when we can get to see this functionality. Thanks!

Let's say we have an grid with incell editing and navigation enabled. But also there may be some column which are readonly (non editable ).  Currently when I press the tab from an editable cell it focus on non editable cell's ,which is no needed. I'll prefer to have a navigation which is stopping only at the editable cells when I press the tab.  And also I would like to add new row when I press the tab form last editable cell in the last row.

Possibility for the user created conditional formatting in the kendo grid. Column background color, text color, line background color, icon, etc, with user condition. There is an example https://jsfiddle.net/magomes/ptwbh0ec/11/, I didn´t work on the dialog layout, but that is the idea and maybe an initial solution.
