Property Value

Type	Description
ASPxGridViewDetailRowButtonEventHandler	A delegate method that allows you to implement custom processing.

Remarks

The grid fires the DetailRowGetButtonVisibility delegate property for each data row. It allows you to hide/show the expand buttons for an individual data row. For example, you can hide expand buttons for data rows whose details have no data.

C#

settings.DetailRowGetButtonVisibility += (sender, args) =>    {  
    var detailRowHandlerGrid = (MVCxGridView)sender;  
    var value = detailRowHandlerGrid.GetRowValuesByKeyValue(args.KeyValue, "YourFieldName");  
    if (value == somevalue)  
        args.ButtonState = GridViewDetailRowButtonState.Hidden;  
};

Note

The grid does not raise the DetailRowGetButtonVisibility delegate property if the ASPxGridViewDetailSettings.ShowDetailButtons option is set to False.
