I have a grid with a column format {0:d} when passing in a null value its returning 12/31/1969.

<GridColumn

key= {"InvoiceDate"}
title= {"Inv Date"}
width= {85},
show= {true}
format= {"{0:d}"}
}

Any suggestions? 

I copied the window component from the example(https://www.telerik.com/kendo-react-ui/components/dialogs/window/) and wanted to build a form on top of the window component. The drop down list of values is showing behind the window. I tried adjusting the z-index but was unsuccessful. I have attached an example of what i'm seeing. The only additional code I added to the example is shown below. "values" is an array of values from 1-20.

We have applied a custom style to grid cells as below,

<Column key={groupArray[0]} title={currentTabColumns[groupArray[0]]} width="148px" field={groupArray[0]} cell = {RerValue} />

the extended class is as below,

export default class RerValue extends GridCell {
render() {

const style = {
backgroundColor: 'red'
};

return <td style={style}> {data} </td>;

}

but now the editing stops. If we remove the custom style the editing works.

Please guide us on how to make this work.

I need to offer the user a "Reset Grid" Button that they can use to reset the grids column widths back to their original values where all columns neatly fit in the viewable area.

I'm doing this in React and Redux based app and we have one column that doesn't have a width, call it the flex column, as we want the grid columns to sick to the edges of the grid and have the flex column adjust in size so all the columns fit perfectly. This works great on initial load. However if the user adjust columns so the width is wider than the grids viewable area and the grid shows a horizontal scroll bar then when the user clicks "Reset Grid" and we give the grid the original column configuration (same one we gave it originally which worked at that time with the flex column not having a width) the grid is fit to the width of the horizontal scrollable area and not of the viewable area meaning we still have horizontal scroll bars and the columns aren't all in view.

How do we accomplish reset like in the older grid and shown here: https://plnkr.co/edit/htk7JcHcWn4Vq8ok4T8l?p=preview

I've run into an issue when using both grouping and a custom cell with a react grid. A new column seems to be created in the grouping row, and the other rows are pushed to the left, which causes the headers to no longer line up.

Here's a link to a fork of the grouping example from the docs, with a custom cell added that shows this: https://stackblitz.com/edit/react-t9ce44?file=app%2Fmain.js

Did I miss something, or is it bugged?

Hello,

In a react grid, i have an editable text field. I discovered that the whole grid was re-rendered after each keystroke. Depending on the size of the grid and its complexity, this may slow down the cell edition.   

Is it possible to only re-render the edited cell ? How can I speed up cell edition ?

Regards,

Jean-Pierre

Step to reproduce:

Case 1:
1. Go to documentation page: https://www.telerik.com/kendo-react-ui/components/dropdowns/multiselect/filtering/
2. Type “ar” symbols

Actual result: Focused element is Bulgaria instead Armenia

Expected result: The first element in list focused - Armenia

Case 2:

1. Go to documentation page: https://www.telerik.com/kendo-react-ui/components/dropdowns/multiselect/filtering/
2. Type “ary” - Hungary is suggested

3. Remove "y" to search "ar"

Actual result: There is no selected element
Expected result: The first element in list focused - Armenia

Is there a way to fix this behaviour?

Hi,

Do we have any combine control for datetime picker? I checked in website and found that there are two different controls one for date and one for time i.e. datepicker and timepicker.

But in my case, I want only one control where I can add date and time manually as well as through calender and time selector.

Regards,

Parag

I am working with a kendo react grid, and i need to implement to open a menu by right clicking on any cell.  By using onContextMenu on the cell render, I am able to open a popup:

cellRender(tdElement, cellProps) {
        const dataItem = cellProps.dataItem;
        const field = cellProps.field;
        const additionalProps = (cellProps.dataItem[this.editFieldName] && (cellProps.field === cellProps.dataItem[this.editFieldName])) ?
            {
                ref: (td) => {
                    const input = td && td.querySelector('input');
                    if (!input || (input === document.activeElement)) { return; }
                    if (input.type === 'checkbox') {
                        input.focus();
                    } else {
                        input.select();
                    }
                }
            } : {
                onClick: () => { this.enterEdit(dataItem, field); },
                onContextMenu: (e) => { e.preventDefault(); this.onContextMenu(e, dataItem, field); }
            };
        return React.cloneElement(tdElement, { ...tdElement.props, ...additionalProps }, tdElement.props.children);
    }

...

Is it possible for a Popup to detect that it has lost the focus, and then set show property to false ?

Best regards.

PS: Maybe there is a better solution to implement a context menu ?

I have seen a real time chart demo for Kendo UI for Jquery

https://www.telerik.com/forums/redraw-in-real-time

https://demos.telerik.com/kendo-ui/chart-api/benchmark

Is there a similar example of a real time chart for the Kendo Components for React?
