How do I remove or hide the data value not required from table in birt tool?
I tried with the values it works in some places but now in groups which has multiple values.
I need to filter some of the values which should not be displayed in the data tab of the table.
I have a column which does not have any value that I need to filter out (But its not an empty value because when I check I got to know that it has some blank spaces). It should display only the columns with non-blank value.
How can I remove those columns from the data set.
You can of course try scripting the data source query but you can also run a script on the table when it is created to hide the empty column.
Try this script in the table's onCreate event:
var mycolumnCount = this.getRowData().getColumnCount();
var DisNull = false;
for(i=1;i<mycolumnCount;i++) {
var temp = this.getRowData().getColumnValue(i)
if(this.getRowData().getColumnValue(i) == "") {
DisNull = true;
}else{
DisNull = false;
i = mycolumnCount+1;
}
}
if(DisNull == true) {
this.getStyle().display = "none"
}

My Interactive Grid has column caled "EMPL_STAT1".
I use the code below to get the return value of the select list from selected record.
Works fine but I was wondering how to change that code to get the return value of the select list from each record (not selected only) in "EMPL_STAT1" column?
Could you give me any advice?
var reg = apex.region('ig_emp').widget();
var grid = reg.interactiveGrid("getViews","grid");
var model = reg.interactiveGrid("getViews","grid").model;
var selectedRecords = grid.getSelectedRecords();
for (i = 0; i < selectedRecords.length; i++)
{
record = model.getRecord(selectedRecords[i][0]);
itemcodeField = model.getFieldKey("EMPL_STAT1");
alert(record[itemcodeField].v);
}
The Javascript you shared, gets the selected row records only.
Let's say my IG's static ID is igTest
var model = apex.region("igTest").widget().interactiveGrid("getViews", "grid").model;
model.forEach(function(igrow) {
console.log(igrow[model.getFieldKey("FIRST_NAME")]);
});
This will loop through all the records in the IG.
I have a simple function that I'd like to run on the values in a column, resulting in another column.
let
ThisIsNotNull = (input) => if (input = null) then false else true,
Source = ...
eventually there is a text column with Nulls in it, let's call it TextColumn.
I'd like to add another column alongside it with a value of =ThisIsNotNull(TextColumn).
Add column... Custom column with formula
= ThisIsNotNull([NameOfColumnToTest])
But really you can skip the function and just use
= if [NameOfColumnToTest] = null then false else true
I have multiple values for one parameter i want to fetch data for each query for every value of parameter in Birt report. i'm getting data only for one value of parameter not all. m using Scripted data source.Open and fetch methods.Thanks
Open in DataSet
importPackage(Packages.com.abc.test.events);
var TlantNo = params["tlant"].value;
var reqNo = params["Number"].value;
poreEvents = new StdPoreReqEvents();
poreEvents.setReqNo(reqNo);
poreEvents.setTlantNo(TlantNo);
poreEvents.open();
fetch
var poreRO = poreEvents.fetch();
if (poreRO == null) {
return false;
} else
{
row["REQ_NO"] = poreRO.getReqNo();
row["REQ_DATE"] = poreRO.getReqDate();
return true;
}
A report parameter with multiple values is an array, we have to iterate on it through the scripted dataset.
In open event of the dataset, we only have to initialize a global index:
i=0;
In fetch event, process each iteration with something such the script below. Pay a special attention how we get the value of reqNo:
importPackage(Packages.com.abc.test.events);
if (params["Number"].value!=null && i<params["Number"].value.length){
var TlantNo = params["tlant"].value;
var reqNo = params["Number"].value[i];
//ETC. do here your stuff with porevents, declare poreRO, check if result is null
row["REQ_NO"] = poreRO.getReqNo();
row["REQ_DATE"] = poreRO.getReqDate();
i++; //Important: increment this even if poreRO is null, otherwise infinite loop
return true; //should return true even if poreRO was null, to process next rows
}else{
return false;
}
The other approach is to do this problem is by defining a dataset having output column which is the multiple value parameter Fetch that column by IN query of the multiple value parameter then pass that value means(output column value) to the other datasets as a Input/output parameter and give binding to parameter.
It resolved my problem :)
I'm trying to work with a LINQ result set of 4 tables retrieved with html agility pack. I'd like to process each one slightly differently by setting a variable for each (switch statement below), and then processing the rows within the table. The variable would ideally be the index for each of the tables in the set, 0 to 3, and would be used in the switch statement and to select the rows. I haven't been able to locate the index property, but I see it used in situations such as SelectChildNode.
My question is can I refer to items within a LINQ result set by index? My "ideal scenario" is the last commented out line. Thanks in advance.
var ratingsChgs = from table in htmlDoc.DocumentNode
.SelectNodes("//table[#class='calendar-table']")
.Cast<HtmlNode>()
select table;
String rtgChgType;
for (int ratingsChgTbl = 0; ratingsChgTbl < 4; ratingsChgTbl++)
{
switch (ratingsChgTbl)
{
case 0:
rtgChgType = "Upgrades";
break;
case 1:
rtgChgType = "Downgrades";
break;
case 2:
rtgChgType = "Coverage Initiated";
break;
case 3:
rtgChgType = "Coverage Reit/ Price Tgt Changed";
break;
//This is what I'd like to do.
var tblRowsByChgType = from row in ratingsChgs[ratingsChgTbl]
.SelectNodes("tr")
select row;
//Processing of returned rows.
}
}
ElementAt does what you're asking for. I don't recommend using it in your example, though, because each time you call it, your initial LINQ query will be executed. The easy fix is to have ratingsChgs be a List or Array.
You can also refactor out the switch statement. It is overkill when you only need to iterate through a list of items. Here is a possible solution:
var ratingsChgs = from table in htmlDoc.DocumentNode
.SelectNodes("//table[#class='calendar-table']")
.Cast<HtmlNode>()
select table;
var rtgChgTypeNames = new List
{
"Upgrades",
"Downgrades",
"Coverage Initiated",
"Coverage Reit/ Price Tgt Changed"
};
var changeTypes = ratingsChgs.Zip(rtgChgTypeNames, (changeType, name) => new
{
Name = name,
Rows = changeType.SelectNodes("tr")
});
foreach( var changeType in changeTypes)
{
var name = changeType.Name;
var rows = changeType.Rows;
//Processing of returned rows.
}
Also, why not store your rating change types in the HTML doc? It seems odd to have table information defined in the business logic.
I have local data in a grid. How can I get all of the rows or IDs that are not removed after a user uses the filter toolbar? I need to get all filtered rows, regardless of pagination.
For example, say I begin with 50 rows in the grid. The user uses the filter toolbar and the set of rows decreases to 10 rows. How can I get those ten rows?
There are no direct way to get the information which you need. Internally jqGrid uses $.jgrid.from to filter local data. The main code which uses $.jgrid.from in inside of addLocalData. To get results which you need without studying all the code I suggest to use the fact that all filtered data will be returned by select method of $.jgrid.from (see the line of code). My suggestion is to catch the data before the data will be cut to the page size.
To do this I suggest to use sub-classing: overwriting of the method select method of $.jgrid.from. I demonstrate the technique in the examples created for the answer and this one.
In your case the code will be
var oldFrom = $.jgrid.from,
lastSelected;
$.jgrid.from = function (source, initalQuery) {
var result = oldFrom.call(this, source, initalQuery),
old_select = result.select;
result.select = function (f) {
lastSelected = old_select.call(this, f);
return lastSelected;
};
return result;
};
Now the variable lastSelected will save the array of elements which are results of the last sorting or filtering operation. Because $.jgrid.from is global the data are not connected to the grid. If you have more as one grid on the page it will be uncomfortable. One can fix the small disadvantage with the following line in the code of loadComplate of every grid:
loadComplete: function () {
this.p.lastSelected = lastSelected; // set this.p.lastSelected
}
In the way we introduce new jqGrid parameter lastSelected which will have close structure as data parameter, but will hold only last filtered data.
The following code will display the ids of filtered data in alert message
$("#getIds").click(function () {
var filteredData = $grid.jqGrid('getGridParam', 'lastSelected'), i, n, ids = [],
idName = $grid.jqGrid('getGridParam', 'localReader').id;
if (filteredData) {
for (i = 0, n = filteredData.length; i < n; i++) {
ids.push(filteredData[i][idName]);
}
alert("tolal number of filtered data: " + n + "\n" +
"ids of filtered data:\n" + ids.join(', '));
}
});
I used localReader.id parameter because property name used for local data are typically id or _id_. The _id_ will be used in case of data loaded from the server if one uses loadonce: true option.
The demo demonstrate the approach. If one filter for example only the data from FedEx and then clicks on "Show Ids" button one will see information about all filtered and not only about the data displayed on the current page:
UPDATED: free jqGrid provides new lastSelectedData option. See the demo in the list of demos.
You colud use afterSearch option of the search toolbar:
var filteredIDs = new Array(); //Global variable
$("#"+gridId).jqGrid("filterToolbar", { stringResult:true, searchOnEnter:false,
afterSearch:function(){
filteredIDs = $("#"+gridId).getDataIDs();
}
});
If you want to get the filtered rows instead the filtered IDs, use getRowData() instead of getDataIDs().
All, I found another answer which is far easier to include
loadComplete: function (gridData) {
var isSearchPerformed = $grid.getGridParam("postData")._search;
if (isSearchPerformed) {
$("#spanFilterTotal").text(gridData.records);
}
All you want is below:
$.each($grid.getRowData(), function( index, value ) {
a.push(value["COLUMN_NAME"]); //Get the selected data you want
});
