I have griview which i have child gridview which open on linkbutton click. and in child gridview i hav dispatch button.onclick of that the data is being saved in databse. after the data is being saved i want to close the nested gridview by making tr.visible=false but not able to do...
and also whenever i click on linkbutton of parent gridview it should check whether child gridview is open in any of the row..if its open then it should be closed and after that on which row it was clicked it should open the child gridview for that particular row.
