Troubleshooting

This article provides solutions for issues you might encounter while working with the Kendo UI Grid for Angular.

Handling of Dates

Dates are not properly formatted. During sorting, filtering, or editing, dates are treated as strings.

When the Grid data contains dates, they need to be instances of the JavaScript Date object. This ensures that dates are handled correctly during formatting, sorting, filtering, and editing.

Solution

If the data is coming serialized from a remote server or for an unspecified reasons the data contains string representations of dates instead of actual JavaScript Date objects, map the data so that each "date" property has a JavaScript date as value.

protected fetch(tableName: string, state: any): Observable<GridDataResult> {
       const queryStr = `${toODataString(state)}&$count=true`;

       return this.http
           .get(`${this.BASE_URL}${tableName}?${queryStr}`)
           .pipe(
               map(response => (<GridDataResult>{
                   data: response['value'].map(item => {
                       item.dateField = new Date(item.dateField);
                       return item;
                   }),
                   total: parseInt(response['@odata.count'], 10)
               }))
           );
   }
