c# - pivot application windows phone 8.1 navigation -
i developing windows phone application firm.
i've manually created pivot items in basic page. application working fine except button navigation. when click on button inside pivot item navigating desired page when click button navigating pivot item 1 instead of 1 click event originated.
my xaml looks this
<grid x:name="contentroot"><pivot x:name="test" title="test book" fontsize="{themeresource textstyleextralargefontsize}"> <!--pivot item one--> <pivotitem x:name="pitem1" header="item1"> <grid> <grid.rowdefinitions> <rowdefinition height="auto" /> <rowdefinition height="5*" /> <rowdefinition height="5*" /> <rowdefinition height="5*" /> </grid.rowdefinitions> <grid.columndefinitions> <columndefinition width="10*" /> <columndefinition width="*" /> <columndefinition width="10*"/> <columndefinition width="*" /> <columndefinition width="10*" /> </grid.columndefinitions> <button x:name="bt1" grid.row="1" grid.rowspan="2" grid.column="0" grid.columnspan="1" content="" horizontalalignment="stretch" verticalalignment="stretch" borderthickness="0" click="bt1_click"/> <button x:name="bt2" grid.row="2" grid.rowspan="2" grid.column="2" grid.columnspan="1" content="" horizontalalignment="stretch" verticalalignment="stretch" click="bt2_click"/> <button x:name="bt3" grid.row="3" grid.rowspan="2" grid.column="4" grid.columnspan="1" content="" horizontalalignment="stretch" verticalalignment="stretch" click="bt3_click"/> <rectangle strokethickness="0" grid.row="1" grid.rowspan="3" grid.column="0" grid.columnspan="11" stroke="#ff015c1f"> </rectangle> </grid> </pivotitem> <!--pivot item one--> <pivotitem x:name="pitem2" header="item2" > <grid> <grid.rowdefinitions> <rowdefinition height="auto" /> <rowdefinition height="5*" /> <rowdefinition height="5*" /> <rowdefinition height="5*" /> <rowdefinition height="5*" /> </grid.rowdefinitions> <grid.columndefinitions> <columndefinition width="10*" /> <columndefinition width="*" /> <columndefinition width="10*" /> </grid.columndefinitions> <button x:name="bt4" grid.row="1" content="" horizontalalignment="stretch" verticalalignment="stretch" click="bt4_click"/ > <button x:name="bt5" grid.row="1" grid.column="2" content="" horizontalalignment="stretch" verticalalignment="stretch" click="bt5_click" /> </grid> </pivotitem> <!--pivot item two--> <pivotitem x:name="pitem3" header="item3"> <grid > <grid.rowdefinitions> <rowdefinition height="auto" /> <rowdefinition height="10*" /> <rowdefinition height="10*" /> <rowdefinition height="10*" /> </grid.rowdefinitions> <grid.columndefinitions> <columndefinition width="10*" /> <columndefinition width="*" /> <columndefinition width="10*" /> </grid.columndefinitions> <button x:name="bt6" grid.row="1" content="" horizontalalignment="stretch" verticalalignment="stretch" click="bt6_click"/> <button x:name="bt7" grid.row="1" grid.column="2" content="" horizontalalignment="stretch" verticalalignment="stretch" click="bt7_click"/> <button x:name="bt8" grid.row="2" content="" horizontalalignment="stretch" verticalalignment="stretch" click="bt8_click" /> </grid> </pivotitem> for example : if click "bt7" present inside pivot item 3, navigates page , when click button navigating pivot item 1 instead of item 3.
am missing or problem have created pivot item manually?
i'm new c# , xaml. highly appreciated.
update :

your page reloaded when navigating , therefor controls in default state (e.g. pivot on first item).
you can either save/restore state in onnavigatedto , onnavigatedfrom methods, or activate page caching setting page's navigationcachemode enabled or required in constructor.
