something like OnDisplayValue

[Michael]

Hi!

DisplayBinding is called (as I've understand) only one time for record.
Does SfDataGrid have event something like OnDisplayValue (for calling each time after repainting).

Sincerely,
Michael

Hi Michael,

Thank you for using Syncfusion products.

We have analyzed your queries and please find the responses for your queries as below,

Query 1: (DisplayBinding is called (as I've understand) only one time for record)

If we give a MappingName alone in a Column the values are displayed based on the MappingName otherwise if we want to display the value based on other data ,we can use DisplayBinding.

Query 2: (Does SfDataGrid have event something like OnDisplayValue (for calling each time after repainting)

Yes, the SfDataGrid has the CurrentCellValueChanged event which will be triggered when we change the cell values.

I'd like to show cell value (displayed value) depends on value in previous row.
Data in previous row can be changed.

Hi Michael,

Thank you for your update.

We have analyzed your requirement. You can change the value of next row based on previous cell value in the CurrentCellEndEdit event as shown below,

Code Example:

public MainWindow()

        {

            InitializeComponent();           

            this.datagrid.CurrentCellEndEdit += datagrid_CurrentCellEndEdit;

        }

        void datagrid_CurrentCellEndEdit(object sender, CurrentCellEndEditEventArgs args)

        {

            var currentRowIndex = args.RowColumnIndex.RowIndex;

            var rowData = this.datagrid.GetRecordAtRowIndex(currentRowIndex + 1);

            (rowData as BusinessObjects).EmployeeName = "Peter";
        }
