JSRuntime.InvokeAsync not working anymore Version 20.2.0.36

[Thijs van Rijswijk]

Hi,

In my source i use the following for scrolling to a postion in the DataGrid:

var index = await LocalStorageService.GetItemAsync<double>("tripscrollindex");

await JSRuntime.InvokeAsync<object>("scroll", index);

The javascript scroll look like this and comes from your example BlazorApp1Sample1968938411:

function scroll(index) {

    try {

        var grid = document.getElementsByClassName("e-grid")[0].blazor__instance;

        var rowHeight = grid.getRowHeight();

        grid.getContent().scrollTop = (index - 1) * rowHeight;

    }

    catch (err)

    {

        var x = err

    }

}

The error:

Name	Value	Type
▶	x	TypeError: Cannot read properties of undefined (reading 'getRowHeight') at scroll (https://localhost:7092/js/sfdatagrid.js:4:30) at https://localhost:7092/_framework/blazor.server.js:1:3501 at new Promise (<anonymous>) at kt.beginInvokeJSFromDotNet (https://localhost:7092/_framework/blazor.server.js:1:3475) at https://localhost:7092/_framework/blazor.server.js:1:72001 at Array.forEach (<anonymous>) at kt._invokeClientMethod (https://localhost:7092/_framework/blazor.server.js:1:71987) at kt._processIncomingData (https://localhost:7092/_framework/blazor.server.js:1:70029) at connection.onreceive (https://localhost:7092/_framework/blazor.server.js:1:64432) at o.onmessage (https://localhost:7092/_framework/blazor.server.js:1:48766) {stack: 'TypeError: Cannot read properties of undefine…ost:7092/_framework/blazor.server.js:1:48766)', message: 'Cannot read properties of undefined (reading 'getRowHeight')'}	TypeError

In the scroll function the value of the grid = undefined.

Can you help me out please because i need the function because the DataGrid starts on the first item now.

Best regards,
