Hello Friends

I have radgrid(rgphase). In this radgrid's formtemplate, I have a another grid(rgLabor).

I am using rowlick of rgphase with EnablePostBackOnRowClick="true" and AllowRowSelect="true". Now if i edit a row in my radgrid(rgphase) then rglabor grid shows.in rglabor,i didn't use anything for rowclick.problem is When i click on rowclick of rglabor then it fires rowclick(itemcommand) of rgphase and opens rgphase in view mode. I want to restrict this.There should not fire rowclick event of rgphase when i click row of rglabor.

I appreciate your any solution.
