I want to have checkboxes in group header as shown in the below example.
Once I click on the group header checkbox, the child group headers under the clicked group header and the data rows inside it should get checked and when it is unchecked all the datarows under the group header should get unchecked.
Individually if I check and uncheck a checkbox in the datarow,the parent group header should get checked if all the datarows are checked and should get unchecked if any of the data is unchecked under that group header.
Only two specific things that I've found lacking: 1) There doesn't appear to be any functionality for Kendo UI (jQuery) that allows for easily adding new values to a multi-select, which the Telerik RadComboBox appears to have. (E.g., for an email "to" field, selecting from existing contacts or adding a new address.) 2) The responsiveness (cell-phone-friendliness) of the Kendo UI Grid is extremely lacking, specifically if allowing for multiple rows selection. (Namely, trying to scroll down the grid instead selects the rows you swipe over, so you're unable to scroll down to see rows off screen.)
I have some feedback regarding the Kendo UI Grid live demo pertaining to localStorage and the columns. I would like to request some built-in defensive approaches to help if columns are removed or added. For example, a way to detect if a column is missing from a previously saved state.
In the spreadsheet there is a way to delay repainting til bulk editing is complete. Grid does not have such a mechanism easily accessed, however with a grid with a large number of rows, inserting multiple rows takes a long time as each row insert triggers the change event. It can be worked around but would be better if it was supported like spreadsheet.
The grid does not have a auto generated Serial Number or Row number column built in. Although this functionality can be custom built, but I feel this is a basic thing and when you have to use the grid in different places in your program, then duplicating the same code for a simple functinoality sounds over killing and maintenance overhead.
The existing configuration(filterable.extra), can only support 1 or 2 input from the UI. It would be great if multiple filter criterion input from the grid UI will be supported in the coming releases.
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.
At the moment, Remote Validation on the grid does not work with incell editing. I would like to see this restriction removed. Normal validation works with incell editing; however, the remote does not. I should not have to change the appearance and functionality of the grid from incell to to inline just because the standard validation is insufficient. I appreciate that this is not an easy change, but hope you are able to give it some priority.
In the kendo grid, on setting the focus on the groupable button and pressing the enter key to change the sorting order, the focus moves to the start of the page. This is a accessibility concern for users who rely only on keyboard for navigation. They need to begin 'TAB'ing from the start again after selecting an option on the grid groupable button.
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
Right now there are two options for sorting, single and multi-column. We would very much like to use the multisort version, however our users fail to understand the functionality. We suggest a new setting, "ctrl-multisort": Single-sort when clicking and multi-sort when ctrl-clicking, similair to most desktop grid controls.
I would like to request adding RowVersion support to the Kendo UI Grid. Currently, I am using a workaround of setting it during the save event, but you guys really need to fix that.
When grouping one column on a large table, all rows (groups) are expanded by default which consumes CPU/memory. Render time grows. Please add bool property defaultCollapsed. In this case grid would not expand all rows(groups) by default. Current work around is to call collapseGroup, but performance would be a lot better if rows could be collapsed by default.
