Hi Himmat, 

 

We would like to inform you that this is the current behavior of Gantt.  

Even for manually scheduled tasks, the date will get validated based on DayWorkingTime. Validation is restricted only for weekends, holidays. 

To render the tasks as given in the data source please set the working time as like below code example. 

 

 

<e-gantt-dayworkingtimecollection> 

      <e-gantt-dayworkingtime from="0" to="24"></e-gantt-dayworkingtime> 

</e-gantt-dayworkingtimecollection> 

 

Please get back to us if you need more information on this.

Hi Himmat, 

  

The reported problem can be resolved by setting the timezone property for Gantt. Please refer below documentation link for more details. 

https://ej2.syncfusion.com/aspnetcore/documentation/gantt/timezone/  

  

Also to restrict time conversion in server side, we can include the below code snippet in startup.cs file 

  

services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1) 

.AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver()) 

.AddJsonOptions(opt => opt.SerializerSettings.DateFormatHandling = Newtonsoft.Json.DateFormatHandling.MicrosoftDateFormat) 

.AddJsonOptions(opt => opt.SerializerSettings.DateTimeZoneHandling = Newtonsoft.Json.DateTimeZoneHandling.Local); 

  

  

Please get back to us if you need more details on this.

Hi Himmat,

Hi Himmat, 

 

Thank you for sharing a sample. 

 

However, we were unable to replicate the issues regarding the dates you reported in the sample you shared. Please find the screenshot of the output we received through the sample you shared with us. 

 

   

 

In the above image, we can see that the tasks are rendered in their proper dates as provided in the data. If you feel that the end dates of the tasks are not rendered based on the dates provided in the data, that is because you have also mapped the duration field in your taskfields collection. When both the duration and end date fields are mapped, then the priority is given to the duration field. You can remove the duration field mapping to render the end dates of the tasks exactly as given in the data source.  

 

We would also like to schedule a meeting with you so that we can check your application in live. Please get back to us with your available timings if you are interested in scheduling a meeting. 

 

Regards, 

Monisha.
