How to remeber row selection during paging

[Shannnon]

I am using RadGrid for AJAX, I cannot reserve row selection and status during paging, selected rows are deselected after leaving current page, the sample online has the same issue with both client-side and server-side selection. I am using client-side selection by the way. Any suggestions?

Thanks in advance!

Hello Shannon,

You can refer the following documentation which shows how to persist the selected rows on paging.
Persisting the selected rows client-side on sorting/paging/filtering/grouping

Thank you, it almost works, except the gridHeader is always undefined, so the childNodes are null all the time too. I think

var

 

 

gridHeader = masterTable.get_element().getElementsByTagName("th")[0], is trying to find following "th"

 

   

<th scope="col" class="rgHeader rgExpandCol"> </th><th scope="col" class="rgHeader rgCheck" style="text-align:center;">
<input id="RadGrid1_ctl00_ctl02_ctl02_ClientSelectColumnSelectCheckBox" type="checkbox" name="RadGrid1$ctl00$ctl02$ctl02$ClientSelectColumnSelectCheckBox" onclick="$find("RadGrid1")._selectAllRows("RadGrid1_ctl00", "", event);" /></th>
<th scope="col" class="rgHeader">ID</th><th scope="col" class="rgHeader">column1</th>
<th scope="col" class="rgHeader" style="display:none;">column2</th>............

  but it cannot, please help me.

Thanks!!

Hello Shannnon,

You can try debugging and see what masterTable.get_element() returns.
However, if the grid grid has scrolling enabled, I would suggest that you use the below method to get reference to the header:
