[mapserver-users] Remove Layer based on layer Name C#

[Venkat Rao Tammineni]

Dear Sir

 

     Can you please tell me how remove specific layer or at least clear the
layer form map. I can able to clear the layer based on index.but if I click
clear layer button again it is clearing whatever the 0 position next layer.

 

     For example  my map contains  the layers called  Continents and
countries and states  that is like 

0 ,1, 2 position. If I want to remove continents (0) that is in 0 position ,
if I use MapFunction.Map.removeLayer(0); , it is working fine. If I Click
the same button again countries will be the second position then the country
layer is removing .but I want to remove single layer.

 

  protected void btnClearPointLayer_Click(object sender, EventArgs e)

        {

            if(Page.IsPostBack)

            {

                MapFunction.Map.removeLayer(0);

            }

         

        }



Is it Possible every time  same layer removable(dynamically the same layer
will be adding).

 

I am waiting for your great response.

 

Advanced Thanks

 

Regards

 

Venkat.

Hi,

How about doing this?

layer = MapFunction.Map.getLayerByName("PointLayer");

MapFunction.Map.removeLayer(layer.index);


Best regards,

Tamas
