Hi José,
Thanks for contacting Syncfusion support.
We have checked your query and the cause of the issue is due to not enabling the IsPrimaryKey property in grid. When editing the rows in grid it is must to enable IsPrimaryKey property.
Please refer the documentation link
Please refer the code example
|
<ej:Grid ID="FlatGrid" runat="server" AllowPaging="True">
<EditSettings AllowEditing="True" AllowAdding="True" AllowDeleting="True"></EditSettings>
<ToolbarSettings ShowToolbar="True" ToolbarItems="add,edit,delete,update,cancel"></ToolbarSettings>
<Columns>
<ej:Column Field="OrderID" IsPrimaryKey="true"/>
<ej:Column Field="CustomerID" />
...
</Columns>
</ej:Grid> |
Please let us know if you need further assistance.
