Help needed regarding grid with grouping and paging toolbar
Dear All ,
I have a problem with my grid. I have a grid that contains Grouping and at
the same time paging . My problem is that my datas are not displayed
correctly . I have datas that display as Top 20 countries in each month . ie
for january,top20 countries will dispaly,for february top 20 countries will
display like that . Datas are displaying ,But problem is while displaying
for eg,for january it will display first six countries( 1 to 6 ),then in
next page again january 7 to 12 Countries ,then next page 13 to 19 countries
then in fourth page remaining 20th country . Like that for every month .
What i need to display is first top 20 countries for january,Then Top 20
countries for february etc.
For eg, Datas in the first page.see feb 2009
Order : Country
Feb 2009
1 : usa
2 : china
3 : Britain
4 : france
5 : italy
6 : russia

Below is my code for the grid.
RecordDef recordDef = new RecordDef(createfieldDefs());
final GroupingStore store = new GroupingStore(new
GWTProxyImpl(), new ArrayReader(recordDef), true);
//store.setBaseParams(new UrlParam[]{new UrlParam("paramName",
"paramValue")});
store.setSortInfo(new SortState("order_num", SortDir.ASC));
store.setGroupField("up_to");
GroupingView gridView = new GroupingView();
gridView.setForceFit(true);
gridView.setGroupTextTpl("{text} ({[values.rs.length]}
{[values.rs.length > 1 ? \"Items\" : \"Item\"]})");
GridPanel grid = new GridPanel(store, createColModel());
grid.setView(gridView);
grid.setWidth(650);
grid.setHeight(600);
grid.setLoadMask(true);
grid.stripeRows(true);
grid.setCollapsible(true);
grid.setAnimCollapse(false);
grid.setTitle("Report Title");
final PagingToolbar pagingToolbar = new PagingToolbar(store);
pagingToolbar.setPageSize(60);
pagingToolbar.setDisplayInfo(true);
pagingToolbar.setDisplayMsg("Displaying records {0} - {1} of

pagingToolbar.setEmptyMsg("No records to display");

pageSizeField.addListener(new FieldListenerAdapter() {
public void onSpecialKey(Field field, EventObject e) {
if (e.getKey() == EventObject.ENTER) {
int pageSize =

Re: Regarding an Uncaught Exception Displaying
Hi,
Thanks for your reply.
I am pretty new to GWT . Please dont harsh on me if i asked any foolish
question.
I am not using an Absolute Panel . I am using
Panel(com.gwtext.client.widgets.Panel) .
I am using a similar application like http://www.gwt-ext.com/demo/ .
There they are using Panel.

Re: Regarding an Uncaught Exception Displaying
Panel;
}
*
Here *ChartServletNew* is a Servlet which is used to create the xml of
fusion chart. Inside this *ChartServletNew *there is a link attrubute in
which will call a javascript function which in turn will call the Servlet
again.
This is done in this manner
*xStreamWriter2.writeAttribute("link","JavaScript:updateFusionChart(\""+newCondQuery+"\",\""+funcNameList.get(k)+"\",\""+statusNameList.get(k)+"\",\""+DrillDownKPI+"\"
);");
*
Below is my javascript function
*function updateFusionChart(condQuery,Mngmnt,stutus,kpi,serviceID){
if ( !serviceID){
var strURL = "ChartServletNew?GM=" + Mngmnt + "&status=" +stutus
+ "&kpi=" +kpi+ "&condQuery=" +condQuery;
strURL = escape(strURL);
var chart_CityDetails = new
FusionCharts('FusionCharts/StackedBar3D.swf?ChartNoDataText=Click right
chart to view Services Details',
'ServDetails', '550', '450', '0', '1');
chart_CityDetails.setDataURL(strURL);
chart_CityDetails.render(Mngmnt+kpi+"ServDetailsDiv");
}
else if (serviceID){
var strURL = "ChartServletNew?GM=" + Mngmnt + "&status=" +stutus
+ "&serviceID=" +serviceID + "&kpi=" +kpi+"&condQuery="+condQuery;
//URLEncode it - NECESSARY.
strURL = escape(strURL);
var chart_CityDetails = new
FusionCharts('FusionCharts/StackedBar3D.swf?ChartNoDataText=Click right
chart to view Services Details',
'SubServDetails', '800', '450', '0', '1');
chart_CityDetails.setDataURL(strURL);
chart_CityDetails.render(Mngmnt+kpi+"SubServDetailsDiv");
}
else {
//Show error
alert("Please wait for the charts to load.");
return;
}
}
*
So like this it will again call the GWT fusion chart calling method and
give the appropriate chart.
So according to my issue if i loaded a page with a fusion chart and clicked
on the link attribute on the fusion chart,then the second time i am loading
another page with

So what may be the reason it is working perfectly in mozilla firefox and not in IE. Whether Mozilla firefox already have this OOPHM plugin . Could any one give me more informations regarding OOPHM with respect to my issue.?

Re: How to call a servlet from GWT
In my GWT class i was calling the servlet "ChartServlet" in the below manner Map parameters = new HashMap(); String chartName = "StackedColumn3D"; String dataUrl = GWT.getModuleBaseURL() + "*ChartServlet*"; FusionChart fusionChart = new FusionChart(chartUrl, 450, 400, dataUrl, parmParametersProvider) ; So my requirement is to pass a method along with the Servlet call Instead of String dataUrl = GWT.getModuleBaseURL() + "*ChartServlet*"; is it possible like this String dataUrl = GWT.getModuleBaseURL() + "*ChartServlet?* "+this.getParams(parameters); getParams will return a String value. But in the Fusion Chart it is showing " Invalid XML Date " Chart is not displaying. Or is there any better way to do this. Please help to solve this issue.

How to Reload or Refresh the page
Dear All,
I am very new to GWT.
I have a doubt.
I have a page that contains a Grid and a Chart.The Grid has a button
that can filter the values of the grid according to the Date what i am
giving in FromDate and ToDate field.
In the same page i have a FusionChart which is gererated from a
servlet.
Currently if i am filtering the Grid, Grid is getting filtered,But
chart will be the previous chart that i loaded before.
My requirement is when i am clicking on the filter button the changes
that i got in grid page shold be reflected in Chart also.
this is what i am doing currently when clicked on Filter button,
ButtonListenerAdapter listener = new ButtonListenerAdapter() {
public void onClick(Button button, EventObject e) {
button.setText("Filter");
store.reload();
}
};
where store is a ' GroupingStore '.
Currently Chart is loaded along with the Grid in the first time. But when i
cahnged the Date that changes is reflecting only on Grid.I want to reflect
these changes to Chart also.
My Grid is working perfectly.
As i am new to GWT i dont know it is a simple or a difficult quesion.
Please Help ...
