Currently the new select column and the "selectable" setting of the grid are mutually exclusive. This seems completly counter intutive. If you you have a select column and the "selectable" mode set to "multiple", then when you drag select or ctrl click on row the checkbox to be selected. Right now it's not.
Currently, pressing the arrow keys will scroll up and down the grid. It would be good if we could also use the arrow keys to change the selected row
It would be nice to have the option to configure different column titles for the column menu. For example, when there is a multi-header Grid, you could use this functionality to add the header title to the column title. https://www.screencast.com/t/qgeK9fFMPP https://www.screencast.com/t/NRl61JFzFH
With out using the group column header(columns.columns). it is better to enable one option to keep some of the columns locking together in the grid. If you reorder one column other columns should move with it like that. When we use the columns.columns option we can't find the columns under that header using the column Index (column[index]) option.
Allow changing Grid's AutoComplete filter operator per Grid (not for each column) through a property
It seems that you would want to conditionally have clearSelection() behave differently with persistSelection enabled, as it does not clear the selection of items on other pages. At the very least offer us a clearAllSelections() method if modifying the behavior of the other method is not desirable.
Add property that defines a delay before requesting new items when scrolling. This would prevent sending multiple request when dragging the scrollbar and passing more than one page.
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.
The popup dialog used by the Grid control does not match the Dialog control. With the same theme applied, the title bar is different (height, font size, and close button), and the button bar footer layout is completely different (button shape, size, and location). By default, dialog look & feel should be consistent across controls using the same theme.
The new event should fire as soon as the grid is fully rendered und ready to take user input or focus. We need this for automated UI Testing. SetTimeout does not work reliable.
Frozen Columns is a really useful addition to the grid, but we're not able to implement it at present as we don't want to force our users to always have one column locked. We don't want to dictate which column that should be, e.g. fixing the LH column. If we could enable Frozen Columns giving the user freedom to freeze one or more columns of their choice, that would be ideal.
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.
We were interested in an option for aggregation rows on top of kendo grid groups. Now they are by default on the bottom of the group which some business users don't like.
