Edit mass Calculation field

DavidAshton

I have the editing tools (editor widget) up and running but I've been looking into a providing my end users a way to select several features (via spatial selection or attribute query) and do a mass attribute calculation.  I have the selection tools in place now I'm looking for examples, directions, and/or thoughts on how to allow my end users to assign a value to a certain field for all the selected features. 

Thanks

I think you nailed it. I'm just unsure how to

Something like:

void MassChange(IEnumerable<Graphic> graphics, string attName, object newValue)
{
  foreach(var g in graphics)
    g.Attributes[attName] = newValue;
}

then you can call MassChange either with the selected graphics of the layer:
               MassChange(graphicsLayer.SelectedGraphics, attName, newValue);
or with the selected graphics in the datagrid:
               MassChange(featureDataGrid.SelectedGraphics, attName, newValue);
or any list you populated by code:
               MassChange(myListOfGraphic, attName, newValue);
