In trying to create this my client noticed that it is harder to report a problem than to to try and use your product

[Lloyd Sheen]

FIrst off this forum is not easy to use.

The problem is with the sfDataGrid.  The clients question and a legitimate one, is why in a thing like a GridTextColumn is there no way to change the font size.  I could not answer that so I suggested using a GridTemplateColumn.  That went further south.  When I did I got the following error:

System.ArgumentNullException: 'Value cannot be null.

Parameter name: key'

Now since "key" is not a property in anything I see in this type of column I am ready to throw my hands in the air and declare your product gone.  Another question I cannot answer is why you put error messages that the developer has no idea what it means.

I spent about a couple of hours with your development team and I either need to talk with them again or I will have to accept that your product is just not of good enough quality for them to use.

Hi Lloyd, 

Regarding “Font Size for GridTextColumn”. This can be achieved by using the CellTextSize property of the GridColumn to set the Font size of the GridTextColumn. Please refer below code snippets for CellTextSize property. 

Code Snippet: 

<sfgrid:SfDataGrid.Columns> 

                <sfgrid:GridTextColumn MappingName="OrderID" CellTextSize="12" /> 

                <sfgrid:GridTextColumn MappingName="CustomerID" CellTextSize="20"/> 

                <sfgrid:GridTextColumn MappingName="ShipCountry" /> 

                <sfgrid:GridTextColumn MappingName="Customer" /> 

… 

</sfgrid:SfDataGrid.Columns> 

 

Please refer our User Guidelines documentation regarding CellTextSize property in below link. 

UG link: https://help.syncfusion.com/xamarin/datagrid/column-types#celltextsize 

Regarding “System.ArgumentNullException: 'Value cannot be null.” Exception. We are unclear about the reported issue; could you please share more information about it, including code snippets? It will be more helpful for us to proceed further on this. 

Regards, 

Suja
