I'm using SmartGWT 2.5.
I have a main grid that has its expandable rows in order to display subgrids.
I simply want to display the main grid with all its rows expanded from the start.
I tried to add a listener containing the following code:
ListGridRecord[] records = getRecords();
for (ListGridRecord rec : records) {
expandRecord(rec);
}
I tried with DataArrivedHandler and DrawAreaChangedHandler, but I just get javascript errors client-side or only parts of the rows are expanded. How can I fix this?
If you are talking about Grid Grouping, then you can use the following:
grid.setGroupStartOpen(GroupStartOpen.ALL);
listGrid.addDataArrivedHandler(new DataArrivedHandler() {
#Override
public void onDataArrived(DataArrivedEvent event) {
for (ListGridRecord rec : listGrid.getRecords()) {
listGrid.expandRecord(rec);
}
}
});
Should work (worked with previous versions..)
What error do you get?
Ok finally, I've put a timer of 100 ms within each handler.
The issue was that there was a delay before the full creation of the components (what I want to display is quite complex), and so when the handler was called, not everything was in place yet...

I have 2 CustomTables with same column names. They are created using expandratio width.
I added resizecolumnlisteners to them so when user column in table1 resize also table2 and vice versa. Problem is when resizing with
List<Values> list;// list of objects in table;
table1.addresizeColumnListener(new resizeColumnListener(){
private void resizeColumn(Event)
{
for(int i=0; i<list.size(); i++)
{
table2.setColumnWidth(list.get(i), table1.getColumnWidth(list.get(i)));
}
}
in table changes only column where listener is fired all others dont change, only when i click any column again all column's widths in table2 is set from table1.
I have too low stackoverflow reputation level to add a comment - so I'm writing this answer.
First of all: Which version of Vaadin do you use? I can't find the function which you used:
table1.addresizeColumnListener(...)
In Vaadin latest documentation is addColumnResizeListener.
And I have doubt why you want change size of all column after notification that one column has been changed? I imagine that after each column size change the Table.ColumnResizeEvent should be emit.
I think the problem you are facing is that when you re-size something in the browser, it will not get sent to the server straight away. The update to the server is sent to the server along with the next update request. That is why you get the delayed update to the UI (if I understood it correctly).
To fix this you can try the code below. Notice the setImmediate(true). This will basically tells Vaadin that you want any update to the table to be sent to the server immediately when the user modifies the table properties.
Try this:
table1.setImmediate(true);
table1.addColumnResizeListener(new ColumnResizeListener(){
#Override
public void columnResize(ColumnResizeEvent event) {
table2.setColumnWidth(event.getPropertyId(), event.getCurrentWidth());
}
});
table2.setImmediate(true);
table2.addColumnResizeListener(new ColumnResizeListener(){
#Override
public void columnResize(ColumnResizeEvent event) {
table1.setColumnWidth(event.getPropertyId(), event.getCurrentWidth());
}
});
In my application I have a <p:datatable> with rowExpansion column. I have a requirement to open a single row at a time. If anyone tries to expand second row, remaining first row expanded then one message will be generated saying First close the expanded row and then open another row.
How this can be implemented ? Any pointer will be very helpful to me. Thanks
As of 2015, and this question is first in Google search results, I want to add that for PrimeFaces 5.1, there is dataTable attribute rowExpandMode, when set to single - allows only one row to be shown. Example:
<p:dataTable var="line" value="#{bean.lines}" rowExpandMode="single">
It's not exactly what was asked, but I hope that it'll help to others.
You can use (I have tested it in mojarra 2.1.20 and Primefaces 3.5 and it works fine) the following solution which calls a JavaScript function when the row is expanded. When clicking on a second row, and there is another expanded row, it will trigger a click event, which will in turn collapse the previously opened row.
xhtml:
<p:ajax event="rowToggle" onstart="test();"/>
Javascript:
<script type="text/javascript">
function test(){
var i = $('.ui-row-toggler.ui-icon-circle-triangle-s').length;
if(i == 1){return;}
$('.ui-row-toggler.ui-icon-circle-triangle-s').trigger('click');
}
</script>
Check out the datatable.js file in Primefaces here. There is a javascript function called toggleExpansion.
Maybe you can override this function and call the original one when no row is expanded and show a message when another row is already expanded (and not call the original one).
Just an idea...
you can achieve this with the help of this custom method.
give 'togglerClass' this class like
<pou:column styleClass="togglerClass" style="width:16px">
<pou:rowToggler/>
</pou:column>
JavaScript code here;
function prodsToggler() {
$('.togglerClass div').click(function () {
var currentTr = $(this).closest("tr");
var $trs = $('.togglerClass').closest("tr").not(currentTr);
$trs.each(function (index, el) {
var $this = $(el),
$next = $this.next(".ui-expanded-row-content");
$this.removeClass("ui-expanded-row");
$next.remove();
$this.find(".ui-row-toggler").removeClass("ui-icon-circle-triangle-s");
});
});
}
call this method in windows ready.
I have a problem with JQuery table sorter pager plugin.
I am trying to use paging with AJAX call. It seems to work OK for most cases, but I am unable to get the sorting working.
The problem is that when the request is made it always looks like (assuming the code from example here):
http:/mydatabase.com?page=0&size=100&{sortList:col}
just like the last parameter {sortList:col} is never actually replaced with proper sorting column.
If I'm reading the example correctly the request for sortList = [[2,0],[3,0]] should actually look like:
http:/mydatabase.com?page=0&size=100&col[2]=0&col[3]=0
But in my case it never is. Also when I click on the header the sorting is performed, but no request is made.
Is there anything I am missing in the linked example?
EDIT
The first part of my problem has been solved by replacing the plugin with the newest version.
For the second part, I still cannot get a request when clicking (sorting) columns. The ajaxProcessing function is almost exactly the same as in the example here, only headers variable is renamed.
As Mottie sugested I am posting an example result from AJAX call (MS MVC JsonResult):
{
"total_rows":1,
"headers":["Id.","Date","User name","File name","status","Hash","Link"],
"rows":[
{
"Id":"21",
"ReceiveDate":"02.12.2012",
"UserName":"John Doe",
"FileName":"test.txt",
"Status":"",
"Hash":"4A71FD2E12F7E04ED0C04E17476BD1BC5F823C8F",
"FileNameLink":"\u003ca style=\"padding-left:10px\" href=\"GetFile?Id=21&fileName=test.txt\"\u003eSave\u003c/a\u003e"
}]
}

I apologize, but I didn't get a chance to thoroughly test the latest changes to the pager. Some of the code was written by someone else, so I might have missed something obvious.
Anyway, this might be the bug that is causing you problems. It resets the table to the first page after each sort... I'll have fixed in the next update.
In the pager plugin, lines 460-470 is this code:
.bind('filterEnd.pager sortEnd.pager', function() {
//Prevent infinite event loops from occuring by setting this in all moveToPage calls and catching it here.
if ($.data(table, 'pagerUpdateTriggered')) {
$.data(table, 'pagerUpdateTriggered', false);
return;
}
c.page = 0;
updatePageDisplay(table, c);
moveToPage(table, c);
changeHeight(table, c);
})
Just change the c.page = 0 to this:
if (e.type === 'filterEnd') { c.page = 0; }
and add an e to the function(e).
I'm trying to dynamically populate a select tag at load time (latest jQM version) using a custom template filling function.
If the fn is called in the "pagebeforechange" event, the select tag is properly initialized. Since this event is called on every page transition, I thought of moving the fn to the 'pageinit' event. This does not work, presumably because the DOM is not yet fully available. How can I coerce jQM to inject content in a page only once? Currently, I am using a kludge. There surely must be a smarter way. Thanks for any suggestions.
$(document).bind('pageinit', function () {
InitSelTagTest("#selActTag", "tplTag"); // Does not work.
});
$(document).bind("pagebeforechange", function (e, data) {
if ($("#selActTag").children().size() === 0) {
InitSelTagTest("#selActTag", "tplTag"); // Kludge, but it works
}
});
function InitSelTagTest(el,tpl) { // Append all tags to element el
var lstAllTags = JSON.parse($("#hidTag").val()); // Create tag array
// Retrieve html content from template.
var cbeg = "//<![" + "CDATA[", cend = "//]" + "]>";
var rslt = tmpl(tpl, { ddd: lstAllTags }).replace(cbeg, ").replace(cend,");
$(el).html(rslt).trigger("create"); // Add to DOM.
}
EDIT
In response to Shenaniganz' comment, it seems that the "pagebeforecreate" event could do the trick ie.
$("#pgAct").live("pagebeforecreate", function () {
// Populate tag select. Works. Traversed only once.
InitSelTag("#selActTag", "tplTag");
});
I'm not sure I fully understand your question but I'll throw a few things out there and you let me know if I can extend further.
To make something trigger only once on page load you can try to implement a regular JQuery $(document).ready(function(){}) aka $(function(){}) for the exact reason why JQuery Mobile users are told not to use it. It triggers only once on DOM load. Further pages don't trigger it because they're being switched via Ajax.
Other than that, on regular dynamic content loading you take a look at the following example I put together for someone else earlier:

I have a webpage with multiple jqgrids each with inline editing enabled, "action" column (edit icons) enabled and pager disabled. I need to handle the delete event for each row so that I can process the delete without reloading server-side data. I've looked at the approach mentioned in jqGrid Delete a Row and it's very helpful except I have two questions that are stumping me -
Are there more details around the rp_ge parameter in the delOptions.onClickSubmit event?
My column has the delOptions set as this -
delOptions: {onclickSubmit: function(rp_ge, rowid) {return onRowDelete(rp_ge,rowid);}},processing:true }},
Is there a way to get the grid id from within that event? I'd like to have a generic function that I can use to handle delete events from all the grids on the page. The rp_ge parameter has a gbox which sometimes contains the grid id appended? But I have no idea what it is since i'm not able to figure out when it's populated, when it's not.
function onRowDelete(rp_ge, rowid) {
//hardcoded grid id.. don't like it.
var gridid = '#Grid_X';
//what is this gbox?? can i get grid id predictable from it?
//var gridid = rp_ge.gbox.replace("#gbox_", "");
var grid = $('#Grid_X');
rp_ge.processing = true;
var result = grid.delRowData(rowid);
if (result) {
$("#delmod" + grid[0].id).hide();
}
return true;
}
In the jqGrid Delete a Row approach, the code $("#delmod"+grid[0].id).hide(); is hiding the popup delete confirmation dialog manually. What I noticed is that when the dialog pops-up, jqgrid de-emphasizes the background page (makes it light greyish). But after the popup is manually closed (hidden actually?), the background remains de-emphasized. So it looks like the page doesn't have focus (or even disabled). Any way this can be fixed? This can also be seen on the demo that Oleg wrote.
Any help would be appreciated.
(PS - I would've commented on the same post but I don't have enough points to comment on someone else's answer yet.)
In answer to your second point.
Several examples by Oleg such as this one have the following modification.
$("#delmod" + grid[0].id).hide();
is replaced with
$.jgrid.hideModal(
"#delmod"+grid_id,
{gb:"#gbox_"+grid_id,jqm:rp_ge.jqModal,onClose:rp_ge.onClose}
);
This will return focus after the delete operation.
