Hi Barak, 

 

Thanks for contacting Syncfusion support. 

 

You can be achieved AutoRowHeight  by handling SfDatagrid.QueryRowHeight event and SfDatagrid.GetRowHeight method. SfDatagrid.QueryRowHeight event returns the row height on demand and SfDatagrid.GetRowHeight method returns the height of the row based on the content. Please refer the below code example  

 

//Hooks QueryRowHeight event in SfDataGrid to set the row height on demand 

dataGrid.QueryRowHeight += DataGrid_QueryRowHeight; 

 

private void DataGrid_QueryRowHeight(object sender, QueryRowHeightEventArgs e) 

{ 

    if (e.RowIndex != 0) 

    { 

        //Calculates and sets the height of the row based on its content. 

        e.Height = dataGrid.GetRowHeight(e.RowIndex); 

        e.Handled = true; 

    } 

}

Hi Ashok,

I encounter runtime exception each time I call GetRowHeight() method, and I using GridTemplateColumn in my XAML. Do you have any idea why it crashed when call GetRowHeight()?

SfDataGrid version 15.3.0.33.

Error Message:

    Object reference not set to an instance of an object.

Hi Chiew, 

 

Thanks for contacting Syncfuion support. 

 

We have checked your query and prepared the SfDataGrid sample with GridTemplateColumn and set the RowHeight by handling QueryRowHeight event in SfDataGrid v15.3.0.33 and Xamarin.Forms v2.3.3.180 but we are not able to reproduced the issue, SfDataGrid loaded properly and RowHeight has been calculated based on the GridCell value. For your reference we have attached sample and Screenshot in the below location, please check it. Could you please share your SfDataGrid and Xamarin.Forms version details, SfDataGrid.Columns creation code snippet, tested device details? Otherwise please do revert us by modifying our sample to replicate the issue or share your sample along with replication procedure, that would be more helpful for us to proceed further.

Hi Ashok,

I manage to locked down the root cause of the problem.

If I compile your sample code with Mono Framework 5.4.1.6, and upgrade the Xamarin.Forms to 2.4.0.38779. The program will crashed when call the DataGrid.GetRowHeight().

(see attachment: Mono Framework 4.8.1.png.zip)

But, when I compile the sample code with Mono Framework 4.8.1 (without changing anything, Xamarin.Forms 2.3.3.180), everything work well.

(see attachment: Mono Framework 5.4.1.6.png.zip)

Therefore, when will this be fix in Xamarin.Forms 2.4.0.38779 with Mono Framework 5.4.1.6 ?

CT

Hi Chang, 

 

We are sorry for the inconvenience caused. 

 

We have checked your screenshot and you are using Xamarin.Forms v2.4.0.38779 but we have support Xamarin.Forms v2.3.3.180 to our Syncfusion controls in 2017 Vol 3 SP2 release. Xamarin.Forms v2.4 stable version has been released after we freeze the 2017 Vol 3 SP2 release so this Syncfusion version won’t support Xamarin.Forms latest version. We will provide the Xamarin.Forms v2.4.0.280 support to our Syncfusion controls in our upcoming 2017 Vol 4 main release which will be schedule for rolls out within this week.  

 

You can get the details about the Syncfusion Xamarin.Forms components compatible from the below link:  

  

https://help.syncfusion.com/xamarin/introduction/compatibility-road-map   

  

https://s3.amazonaws.com/files2.syncfusion.com/Installs/v15.3.0.33/ReadMe/Xamarin_Forms.html   

 

Note: We are able to reproduce the reported NullReferenceException with Xamarin.Forms v2.4.0.38779 and SfDataGrid v15.3.0.33 because of Xamarin.Forms version mismatch. This will be work with 2017 Vol 4 main release.
