jxls collection printing order - excel

This is my excel template. Unfortunately, employee.email is ArrayList and can have more than one value.
The result becomes
Actually, aaa1.gmail.com and aaa2.gmail.com belong to AAA and similarly, bbb1.gmail.com and bbb2.gmail.com belong to BBB. The excel output is very misleading in this case.
Is it possible to get as below?
Since I am very new to jxls, any help is really appreciate.

First you need to have a POJO like below to hold the data.
public class Employee {
private int id = 0;
private String name = null;
private List<String> mails = new ArrayList<String>();
// getters & setters
}
Now create data objects that you want to display in your excel file
Employee emp1 = new Employee();
emp1.setId(1);
emp1.setName("AAA");
emp1.getMails().add("aaa1#xyz.com");
emp1.getMails().add("aaa2#xyz.com");
Employee emp2 = new Employee();
emp2.setId(2);
emp2.setName("BBB");
emp2.getMails().add("bbb1#xyz.com");
emp2.getMails().add("bbb2#xyz.com");
List<Employee> employees = new ArrayList<Employee>();
employees.add(emp1);
employees.add(emp2);
then add the data into java.util.Map
Map<String, List<Employee>> beanParams = new HashMap<String, List<Employee>>();
beanParams.put("employees", employees);
then create XLSTransformer object and set the source file, destination file and the map which is holding your data
XLSTransformer former = new XLSTransformer();
former.transformXLS(srcFilePath, beanParams, destFilePath);
you need to use two <jx:forEach> tags to iterate over the list which is in your map and then you can set the values into your result excel file.
Change your excel template file with the following
and the final result will look like

Map to hold multiple sets of key and values

I have a map1 which holds the information as
[40256942,6] [60246792,5]
Now that I want to prepare a map2 that holds information such as
itemNo, 40256942
qty, 6
itemNo, 60246792
qty, 5
to prepare final information as json
“partialArticlesInfo”: [{itemNo:”40256942”, availQty:”6”}, {itemNo:”60246792”, availQty:”5”}]
I am trying to iterate map1 to retrieve values and set that against the key. But I am getting only one entry which is last one. Is there any way , I get the new map with entries such as mentioned above
Map<String, String> partialArticlesInfo = new HashMap<String,String>();
Map<String, String> partialArticlesTempMap = null;
for (Map.Entry<String,String> entry : partialStockArticlesQtyMap.entrySet())
{
partialArticlesTempMap = new HashMap<String,String>();
partialArticlesTempMap.put("itemNo",entry.getKey());
partialArticlesTempMap.put("availQty",entry.getValue());
partialArticlesInfo.putAll(partialArticlesTempMap);
}
In Java (I'm assuming you're using Java, in the future it would be helpful to specify that) and every other language I know of, a map holds mappings between keys and values. Only one mapping is allowed per key. In your "map2", the keys are "itemNo" and "availQty". So what is happening is that your for loop sets the values for the first entry, and then is overwriting them with the data from the second entry, which is why that is the only one you see. Look at Java - Map and Map - Java 8 for more info.
I don't understand why you are trying to put the data into a map, you could just put it straight into JSON with something like this:
JSONArray partialArticlesInfo = new JSONArray();
for (Map.Entry<String,String> entry : partialStockArticlesQtyMap.entrySet()) {
JSONObject stockEntry = new JSONObject();
stockEntry.put("itemNo", entry.getKey());
stockEntry.put("availQty", entry.getValue());
partialArticlesInfo.put(stockEntry);
}
JSONObject root = new JSONObject();
root.put("partialArticlesInfo",partialArticlesInfo);
This will take "map1" (partialStockArticlesQtyMap in your code) and create a JSON object exactly like your example - no need to have map2 as an intermediate step. It loops over each entry in map1, creates a JSON object representing it and adds it to a JSON array, which is finally added to a root JSON object as "partialArticlesInfo".
The exact code may be slightly different depending on which JSON library you are using - check the docs for the specifics.
I agree with Brendan. Another solution would be otherwise to store in the Set or List objects like the following.
class Item {
Long itemNo;
int quantity;
public int hashCode() {
Long.hashCode(itemNo) + Integer.hashCode(quantity);
}
public int equals(Object other) {
other instanceOf Item && other.itemNo == this.itemNo && other.quantity = this.quantity;
}
}
}
then you can use the JsonArray method described by him to get the Json string in output
This means that adding new variables to the object won't require any more effort to generate the Json

How to add to the object of SelectManyCheckbox selected values?

I have an object of SelectManyCheckbox. For this object I set available values in the next way:
SelectManyCheckbox checkbox = new SelectManyCheckbox();
List<Double> selected = new ArrayList<Double>();//this will be used for setting selected values
List<SelectItem> items = new ArrayList<SelectItem>();//this will be used as available values
for (SomeObject av : listOfObjects)
{
SelectItem item = new SelectItem(av.getNumericValue(),
av.getValue());
items.add(item);
if (av.getDefault())
{
selected.add(av.getNumericValue());
}
}
UISelectItems uiItems = new UISelectItems();
uiItems.setValue(items);
checkbox.getChildren().add(uiItems);
checkbox.setSelectedValues(new Double[selected.size()]);
But this way of setting of selected values does not work. Maybe someone know there is the source of the problem?
Your Double[] is empty there, try converting the list to the array like this:
checkbox.setSelectedValues(selected.toArray(new Double[selected.size()]));

SharePoint 2010 - how to make multi-column a unique value

i'm implementing a sand box solution where is should have more than one column a unique key, i have to use the item adding event receiver but how to get the current adding item field values to know if this item is occurred within the list.
thanks
Create UniqueID column and make it unique.
Create an event receiver as follows:
public override void ItemAdding(SPItemEventProperties properties)
{
string Name = properties.AfterProperties["Name"].ToString();
string Title = properties.AfterProperties["Title"].ToString();
StringBuilder StringBuilder = new StringBuilder(Name);
StringBuilder.Append("-");
StringBuilder.Append(Title);
properties.AfterProperties["UniqueID0"] = StringBuilder.ToString();
base.ItemAdding(properties);
}

Creating Data Table from object array

I am not sure if I am going about this the correct way but I have a c# method which loads an excel sheet into a 2 dimentional object array. In this array item 1,1 - 1,16 contain headers, then 2-1 - 2-16 contain data that match up with those headers as do x-1 - x-16 from there on in. I would like to turn this array into a data table so ultimately I can have it in a format I will then import into an access or SQL server db depending on a clients needs. I have tried using the following code to no avail, but I have a feeling I am way off. Any help on this would be very much appreciated.
private void ProcessObjects(object[,] valueArray)
{
DataTable holdingTable = new DataTable();
DataRow holdingRow;
holdingTable.BeginLoadData();
foreach(int row in valueArray)
{
holdingRow = holdingTable.LoadDataRow(valueArray[row], true);
}
}
Any chance you're using a repository pattern (like subsonic or EF) or using LinqToSql?
You could do this (LinqToSql for simplicity):
List<SomeType> myList = valueArray.ToList().Skip([your header rows]).ConvertAll(f => Property1 = f[0] [the rest of your convert statement])
DataContext dc = new DataContext();
dc.SomeType.InsertAllOnSubmit(myList);
dc.SubmitChanges();

What is the correct way to format SPGridView values being displayed?

Problem
As we know, SharePoint saves data in database in plain text. Some fields even have concatenated strings like <id>;#<value> for user fields. Percents are saved as doubles (1.00000000000000 for 100%) and etc.
Ofcourse, I want to display data as they are displayed in lists.
What should I do?
Should I use derived SPBoundField to format values (Which I actually did and it works fine until you want to filter (probably SPBoundField won't format me values because i use ObjectDataSource not list and with reflector I saw if there are SPListItems in datasource, then it formats correctly. Not my case)

Or must I loop through all the DataTable and format each row accordingly?
What are Your techniques?
Thank you.
Here is how I solved this issue.
<asp:TemplateField HeaderText="Campaign Members">
<ItemTemplate>
<%# RemoveCharacters(Eval("CampaignMembers").ToString())%>
</ItemTemplate>
</asp:TemplateField>
// Make sure declare using System.Text.RegularExpression;
protected string RemoveCharacters(object String)
{
string s1 = String.ToString();
string newString = Regex.Replace(s1, #"#[\d-];", string.Empty);
newString = Regex.Replace(newString, "#", " ");
return newString.ToString();
}
I normaly use ItemTemplates that inherit from ITemplate. With in the ItemTemplate I use the SPFieldxxxValue classes or some custom formating code. This saves looping through the DataTable and the ItemTemplates can be reused.
The ItemTemplates are attached in Column Binding
E.G
// Normal Data Binding
SPBoundField fld = new SPBoundField();
fld.HeaderText = field.DisplayName;
fld.DataField = field.InternalName;
fld.SortExpression = field.InternalName;
grid.Columns.Add(fld);
// ItemTemplate Binding
TemplateField fld = new TemplateField();
fld.HeaderText = field.DisplayName;
fld.ItemTemplate = new CustomItemTemplateClass(field.InternalName);
fld.SortExpression = field.InternalName;
grid.Columns.Add(fld);
An example of a ItemTemplate
public class CustomItemTemplateClass : ITemplate
{
private string FieldName
{ get; set; }
public CustomItemTemplateClass(string fieldName, string formatString)
{
FieldName = fieldName;
}
#region ITemplate Members
public void InstantiateIn(Control container)
{
Literal lit = new Literal();
lit.DataBinding += new EventHandler(lit_DataBinding);
container.Controls.Add(lit);
}
#endregion
void lit_DataBinding(object sender, EventArgs e)
{
Literal lit = (Literal)sender;
SPGridViewRow container = (SPGridViewRow)lit.NamingContainer;
string fieldValue = ((DataRowView)container.DataItem)[FieldName].ToString();
//Prosses Filed value here
SPFieldLookupValue lookupValue = new SPFieldLookupValue(fieldValue);
//Display new value
lit.Text = lookupValue.LookupValue;
}
}
Here are a few options. I don't know the output of all of them (would be a good blog post) but one of them should do what you want:
SPListItem.GetFormattedValue()
SPField.GetFieldValue()
SPField.GetFieldValueAsHtml()
SPField.GetFieldValueAsText()
It may also be handy to know that if you ever want to make use of the raw values then have a look at the SPField*XYZ*Value classes. For example the form <id>;#<value> you mention is represented by the class SPFieldUserValue. You can pass the raw text to its constructor and extract the ID, value, and most usefully User very easily.
I would suggest either to format the values before binding them to the spgridview. Linq and an anonymous type is preffered or to call a code behind function on the field that needs the formatting upon binding.
DataField='<%# FormatUserField(Eval("UserFieldName")) %>'
or...maybe a templated field?
After all, i did have not know any other solution to loop through DataTable rows and format them accordingly.
If your SPGridView's data source is list, try out SPBoundField.
