RowHeight

Hello Syncfusion-Team,

I tried to set the RowHeight according to documentation, but got errors. It took me some time to find out what the root cause is.

Using "RowHeight" together with "EnableVirtualization="true"" brings up this error:
    
blazor.server.js:19 [2021-04-26T04:18:02.130Z] Error: System.FormatException: Input string was not in a correct format.
   at System.Number.ThrowOverflowOrFormatException(ParsingStatus status, TypeCode type)
   at System.Number.ParseInt32(ReadOnlySpan`1 value, NumberStyles styles, NumberFormatInfo info)
   at System.Convert.ToInt32(String value)
   at Syncfusion.Blazor.Grids.Internal.VirtualScroll`1.RemovePx(String WidthOrHeight)
   at Syncfusion.Blazor.Grids.Internal.VirtualScroll`1.EnsurePageSize()

   at Syncfusion.Blazor.Grids.Internal.EventAggregator.<>c__DisplayClass2_0.<Notify>b__0(Action`1 handler)
   at System.Collections.Generic.List`1.ForEach(Action`1 action)

   at Syncfusion.Blazor.Grids.Internal.Preloader`1.OnParametersSetAsync()
   at Microsoft.AspNetCore.Components.ComponentBase.CallStateHasChangedOnAsyncCompletion(Task task)

Please have a look at the issue.

Best regards
Michael

Hi Jeevakanth,

your example is working indeed. But it fails as soon as Height="600" is removed from:
<SfGrid DataSource="@GridData" Height="600" EnableVirtualization="true" RowHeight="40" AllowGrouping="true">

Best regards
Michael

Hi Michael, 

We have checked your query and we would like to inform you that when you are using virtualization then you have to set the grid’s height using the Height property. Please refer the below documentation for your reference.

Hi Jeevakanth,

ok, I will do that. Thank you for your help!

Maybe you check the code and add a meaningful exception message for the next developer stumbling over this issue.

Best regards
Michael
