Grid Inline Editing not working when datatable is bound

[Ciprian Daniel]

Hi everyone,

I have binded a datatable to my grid and the Edit Mode was set to Inline. In an Editor template I have added for example TelerikNumericTextBox like this:

<TelerikNumericTextBox Arrows="@false"
                                                                   Value="@((decimal)dataRow[col.ColumnName])"
                                                                   ValueChanged="@((decimal value) => { OnDecimalCellValueChange(col.ColumnName, value); })" />

No when I want to edit the value this error appears

System.InvalidOperationException: Telerik.Blazor.Components.TelerikTextBox requires a value for the 'ValueExpression' ValueExpression is provided automatically when using 'bind-Value'.See more at https://docs.telerik.com/blazor-ui/knowledge-base/requires-valueexpression

I have read the details from that link but it doesn't seam to work, I don't have a model but a datatable binded to my grid.

Is there in this situation a solution?

Best regards,

Cipri

I've changed the implementation suggested here: https://feedback.telerik.com/blazor/1418456-bind-to-datatable

To this implementation: https://demos.telerik.com/blazor-ui/grid/data-table

And then I found the answer in this post: https://www.telerik.com/forums/call-setstate-on-a-grid-that-has-an-onread-handler

It was an issue regarding the call of the method .SetState() followed by OnRead

 

Thank you,

Cipri
