Hi Yatendra,<br> <br>layer.close(); , here layer is the base layer. The code that I have provided is used to colour features in the layer (You can change the entire layer color also). The layer has many features, which can be retrieved using<br>
shapeObj shape = layer.getFeature(shapeInd, -1);<br>"shapeInd" is the index of the shape.<br><br>This is the shape that i use to add into the temporary layer created<br>oTempLayer.addFeature(shape);<br>So, once I add the shape that I want to color to the temporary layer, I close the base layer using layer.close();<br>
<br>I hope this helps.<br><br>Regards,<br>Sucharita<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"></blockquote><br><br><br><div class="gmail_quote">

Dear Sucharita,<br>
I have one more question. U have used<br>
"oTempLayer.addFeature(shape);"<br>
<br>
How to get shape?<br>
<br>
Which layers shape are you talking about? Please clarify my doubt.<br>
I am newbie to <a href="http://asp.net" target="_blank">asp.net</a> mapserver.<br>
