Add an beforeOnchange event that fires to allow additional validation before the change occurs. If returns false then onChange never is fired.

Add ability to have a horizontal scrollbar in the kendoui grid that appears at both the top and bottom of the data set to ease scrolling in large data sets.

Currently in a data grid with virtual scrolling there is no way to scroll to an item. You can filter to that item, but you can't see it in the context of other data. I'm pretty sure this was available in Silverlight rad grid 7-8 years ago.

If you export your grid to Excel then you may have noticed that sometimes the columns are smaller than their content.
What I mean is, I have double click the coumn header in Excel to get the desired "auto-width".
It would be nice to have this functionality already in Telerik.
So that the column width perfectly fits its content.

Currently when using MVVM to instanciate a grid which contains columns with values arrays, those values arrays must be globally scoped.  All other things MVVM binds to are located within the View Model.

Please make it so that the kendo.bind method will allow for an MVVM grid to locate it's columns value arrays within the View Model. 

Show the text in the filterMenu formatted as the text in the column. More info here: http://www.telerik.com/forums/filtering-html-characters

Currently, when kendo grid is initialized from an  already populated html table, there is then no way to freeze columns as there is no datasource specified in kendo grid initialization.

Provide build-in support for filtering and sorting for complex columns like dropdown or Autocompelete with dropdown in grid. Bound value consists of complex objects - one for value and one for text of the dropdown. Right now, sorting is based on value and not text. Please provide options to sort based on text. Filtering doesn't work for these columns. It would be nice to have filtering support for these columns.

Hello, 

A couple feature requests...

Clear the built in search box value.

clearSearch - clears the search box

e.g.,

var grid = $("#grid").data("kendoGrid");
grid.clearSearch();

Customize validation text via schema model fields validation.

e.g.,

var grid = $("#grid").data("kendoGrid");
const dataSource = new (<any>self).kendo.data.DataSource({
                data: models,
                schema: {
                    model: {
                        id: "id",
                        fields: {
                            id: { editable: false, nullable: true },
                            modelName: { validation: { required: true, messages: {required: "Model name is a required field"} } },
                            ...

When scrolling is disabled for a grid and column resizing is enabled, resizing a column acts in a strange manner and attempts to size all columns of the grid.  I would expect that only the two columns on each side of the resize handle should have their widths altered.  Otherwise scenarios can occur where you are completely unable to resize columns.  If this would not be default functionality, I would at least suggest a flag to enable it at grid setup.

We are using kendo Datagrid where we wanted to apply pagination.

We are using pageSizes property of pageable object to set the no of items per page to render. We are also using buttonCount property to control the number of buttons.

Problem : For example I have 200 records , if I set pagesSizes=1 so technically I will have 200 paging button and if i set buttonCount to 60 than UI gets distorted. Find below is stackblitz URL where I have set pagesSizes=1 and if you set Maximum number of buttons = 70 UI will break.

URL : https://cuezkg--run.stackblitz.io/ 

Right now columnMenu is available in each column, along with that, it would be better if there is a centralised option where user can configure the columns.

As explained in this support ticket

I asked me questions about the Kendo-UI Grids toolBar that is only place at the top of datatables.

I’ve been reading on forum thread that, with javascript, we can place it elsewhere but i don’t think that it is very clean code and maintainable.

I'd like this toolbar to be adaptable according to the design I need !

So I suggest to modify/improve this component to fit more situations 
(eg.: 
 - to place it in the "page’s information zone"  for export buttons  
 - to place it at the bottom of datagrid for ending actions’ buttons because at the top is a good place to propose filters to user and way to organize datas
 - etc.) 

or 

to have the possibility to combine many situations (Toolbar & endToolbar & informationToolBar) with multiple toolbars at different places.

Bug: Column Resize Handle not showing on dynamic Grid Columns

The problems are the hidden columns. If you have a hidden column in the grid, you can't resize all other columns after the hidden column. That is a very nasty bug, so please Kendo-UI team make a fix for it.

It would be helpful to be able to format a grids content in a more straightforward manner out-of-the-box. For instance, if a Kendo grid was displaying a typical data matrix like https://en.wikipedia.org/wiki/Triangular_matrix, it would be useful to be able to format by the upper triangular region, lower triangular region, odd rows, even rows, etc.

The grid validation does not work well when the grid is part of a complex form containing simple fields and a Kendo Validator.  See this forum thread: http://www.telerik.com/forums/grid-custom-validation-not-shown

The grid validation should integrate better with a form level kendo validator so you can validate both the grid and the simple fields easily.

Right now kendo's system for alternating rows is to specify rowTemplate and altRowTemplate.  For any non-trivial row template, this makes for a big ugly DRY violation as you copypaste the entire template just to give it a different css class and leave it otherwise identical.  Any future changes to the template have to be made to both copies, and any potential template issues have to be tested on both even and odd numbered rows.

If rowTemplate received whether it's an alternate row as a template parameter, it would be easy to do common things on alternating rows without ever needing to define altRowTemplate.
