Satya,

You just use setSymbol again on that feature again and apply the normal symbol. I would normally set a global var for the current selected symbol that way you know which one to apply the normal symbol to.

Satya,

check out this example: ArcGIS API for JavaScript Sandbox

they use a mouse-over event, first they clear all graphics and then they add a highlight graphic.

Hi,

this is my code

initially set the symbol

symbol321 = new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_SQUARE, 0.1, null, new Color([255, 255, 0, 0.5]));

function onRowClickHandler(evt){

var FindDeceasedName = grid.getItem(evt.rowIndex).FID;

var SelectedFindDeceasedName;

dojo.forEach(map.graphics.graphics,function(graphic){

if((graphic.attributes) && graphic.attributes.FID === FindDeceasedName){

SelectedFindDeceasedName = graphic;

SelectedFindDeceasedName.setSymbol(symbol321);

return;

}

});

var FindDeceasedNameExtent = SelectedFindDeceasedName.geometry;

SelectedFindDeceasedName.setSymbol(highlightSymbol);

var factor = 0.1;

var extent;

extent = new esri.geometry.Extent({ "xmin": FindDeceasedNameExtent.x - factor, "ymin": FindDeceasedNameExtent.y - factor, "xmax": FindDeceasedNameExtent.x + factor, "ymax": FindDeceasedNameExtent.y + factor, "spatialReference": { "wkid": 3857} });

map.setExtent(extent);

}

still previously highlighted is not cleared.

Regds,

Satya

Satya,

So if the symbol321 is the NORMAL symbol then you need to apply that symbol to each other graphic.

        dojo.forEach(map.graphics.graphics,function(graphic){
          //deselect all graphics first
          SelectedFindDeceasedName.setSymbol(symbol321);
          if((graphic.attributes) && graphic.attributes.FID === FindDeceasedName){
            SelectedFindDeceasedName = graphic;
            //Apply the highlight symbol to only the one that matches
            SelectedFindDeceasedName.setSymbol(highlightSymbol);
            return;
          }
        });

Hi Robert,

dojo.forEach(map.graphics.graphics,function(graphic){
//deselect all graphics first
graphic.setSymbol(symbol321);
if((graphic.attributes) && graphic.attributes.FID === FindDeceasedName){
SelectedFindDeceasedName = graphic;
//Apply the highlight symbol to only the one that matches
SelectedFindDeceasedName.setSymbol(highlightSymbol);
return;
}
});

Thanks,

Satya.
