We have prepared the sample using the provided scenario ,code example and we could able to reproduce the reported issue. This issue occurs when you tried to bind the property in DoubleTextBox using the
Text property. To bind the value in DoubleTextBox, the
Value property should be used. Now the value in the DoubleTextBox would get correctly updated in the SfDataGrid. Please download the sample from the following location:
