client side force rebind to page 1 - page number in pager not correct

[Marcel]

Hello,

I am using the client object model. I want to force a rebind of the grid back to page 1. I am having trouble setting the page number in the pager back to 1 (if I am on page 2 before the rebind).

This code does not always rebind - typically when already on the first page, but also under other conditions.

tableView.set_currentPageIndex(0, true);

This code rebinds, but does not reset the page number in the pager to page 1 if I was on page 2.

var tableView = $find(radGridPracticesClientID).get_masterTableView();
tableView.rebind();

So I cannot use this:

if (currentPageIndex == 0) {
    tableView.rebind();
}
else {
    // buggy - does not always rebind - e.g. when new results are less than 1 page
    tableView.set_currentPageIndex(0, true);
}

Finally, this code is equivalent to tableView.rebind() it always rebinds and gets the results for page 1 but does not set the page number in the pager to 1. The page count IS correct.

            var currentPageIndex = 0;
.
.
            PageMethods.GetPracticesAndCount(currentPageIndex, pageSize,
              sortExpressions, filterExpressions, installationID,
              environmentalWeight, regulatoryWeight,
              publicPerceptionWeight, healthAndSafetyWeight,
              includeAspects, includeImpacts, checkedCommandIDs, selectedLocationIDs,
              rebindPracticeGridResult);
        }

function rebindPracticeGridResult(result) {
     var tableView = $find("ctl00_PlaceHolderMain_Practice1_RadGridPractices").get_masterTableView();
     tableView.set_dataSource(result.Practices);
     tableView.dataBind();
     tableView.set_virtualItemCount(result.PracticeCount);
}

Hi Macrel,

I would suggest you to invoke trigger page command for the grid using fireCommand from client side. The method is called for the GridTableView client instance.

Refer the following documentation for more information about using fireCommand from client side.
