I have used BindingSource to bind DataGrid in my window 6.5 application. But problem is that I want to change the text of a column from Int to string while grid is binding.
If you look at below code I am binding DataGrid with Designation which value is 502 but I need to display "SE" instead, I cant take that value in my Candidate object so I need to modify DataGrid at runtime. I dont know how can I achieve this. Please help . Thanks
cand.Add(new Candidate { ID = 10, Name = "Andrew", Designation =501 ,DCode="SSE" });
cand.Add(new Candidate { ID = 11, Name = "Peter", Designation = 502 , DCode="SE"});
DataGridTableStyle myDataGridTableStyle = new DataGridTableStyle();
myDataGridTableStyle.MappingName = "Candidate";
DataGridTextBoxColumn colA = new DataGridTextBoxColumn();
colA.MappingName = "Name";
colA.HeaderText = "Field A";
colA.Width = 50;
DataGridTextBoxColumn colB = new DataGridTextBoxColumn();
colB.MappingName = "Designation";
colB.HeaderText = "Position Holding";
colB.Width = 100;
//dataGrid1.CurrentCell.ColumnNumber.
DataGridTextBoxColumn colC = new DataGridTextBoxColumn();
colC.MappingName = "DCode";
colC.HeaderText = "Code Position";
colC.Width = 50;
myDataGridTableStyle.GridColumnStyles.Add(colA);
myDataGridTableStyle.GridColumnStyles.Add(colB);
myDataGridTableStyle.GridColumnStyles.Add(colC);
myBindingSource.DataSource = cand.ToBindingList();
myDataGridTableStyle.MappingName = myBindingSource.GetListName(null);
dataGrid1.TableStyles.Clear(); // Recommended on MSDN in the code examples.
dataGrid1.TableStyles.Add(myDataGridTableStyle);
dataGrid1.DataSource = myBindingSource;
Why don't you make the DCode property a slave to your Designation property so that:
Canidate c = new Candidate();
c.Designation = 501;
print(c.DCode);//outputs "SSE"
then you can bind to DCode when you just want the string interpretation of Designation.

I have the following code that I cannot make it work.
I am new using Linq and Entity framework.
I attach the code sample, and also, and image with the error.
What I am trying to do, is a piece of code where I can add "Where"s dynamically.
Imports System.Linq
Private cntx As New attmanager_bdEntities()
Dim query = (From persona In cntx.tblperson
Select
ATT_TYPE = persona.att_type,
ATT_RECOG = persona.att_recog,
APELLIDO = persona.surname,
NOMBRE = persona.name,
PERSONA_ID = persona.id,
DNI = persona.identification,
DIRECCION = persona.address,
PIN = persona.att_pin,
TIPOASISTENCIA = persona.att_type,
EMAIL = persona.email,
EXTRA = persona.extra,
TELEFONO = persona.phone,
FECHANACIMIENTO = persona.birth,
SEXO = persona.sex,
DELETED = persona.deleted,
AREA_ID = persona.tblarea.id,
AREA = persona.tblarea.name,
CIUDAD = persona.tblcity.name,
CIUDAD_ID = persona.tblcity_id,
PROVINCIA = persona.tblcity.tblstate.name,
PAIS = persona.tblcity.tblstate.tblcountry.name
Where (DELETED = 0))
query = query.Where(Function(a) a.AREA_ID = 1)
'Here I should put another "Where"s
dbgrid_listado.DataSource = query.ToList()
Error translation:
Unexpected exception trying to load "personas"
Details:
Could not invoke the method because could not call a 'Public Function Where ..........
......
......
......
...... with those arguments.
The parameter 'predicate' of the argument could not be converted to VB$AnonymousDelegate_0(Of Object,Object)' into 'String'
Why not this?
Dim query = (From persona In cntx.tblperson
Where persona.DELETED = 0
Select persona)
Now your type is "persona" instead of an anonymous type of 21 random properties.
query = query.Where(Function(a) a.AREA_ID = 1)
Working with anonymous types is always tricky. Also, I always put the select last...
You could always list out the properties in an anonymous type like this:
Dim query = (From persona In cntx.tblperson
Where persona.DELETED = 0
Select New With {
ATT_TYPE = persona.att_type,
ATT_RECOG = persona.att_recog,
APELLIDO = persona.surname,
NOMBRE = persona.name,
PERSONA_ID = persona.id,
DNI = persona.identification,
DIRECCION = persona.address,
PIN = persona.att_pin,
TIPOASISTENCIA = persona.att_type,
EMAIL = persona.email,
EXTRA = persona.extra,
TELEFONO = persona.phone,
FECHANACIMIENTO = persona.birth,
SEXO = persona.sex,
DELETED = persona.deleted,
AREA_ID = persona.tblarea.id,
AREA = persona.tblarea.name,
CIUDAD = persona.tblcity.name,
CIUDAD_ID = persona.tblcity_id,
PROVINCIA = persona.tblcity.tblstate.name,
PAIS = persona.tblcity.tblstate.tblcountry.name
})
Maybe the where clause using the anon type is messing it up and using persona.DELETED = 0 would help?
I got it ....
I created a new project
I migrate all the resources (images for example) from the old project to this new one.
Opened the NuGet package manager, and installed EF6
Also installed MySQL.Data and MySQL EF6 provider.
I imported the forms, from the original project to the new one.
Now I can do what you guys suggested.
The Problem ??? .... The version on .Net framework, and the EF I was using.
I had t update everything.
I have a stacked column report and i need to show the label value inside each of the series, is this possible. here is the code i have so far. It does look like barcharts have this option, not sure if i need to convert report to that type.
chart.Title.Text = "Total Pipeline - Initiative Count by Release";
chart.Title.Font.Size = 8;
chart.SetPosition(45, 0, 3, 0);
chart.SetSize(400, 300);
chart.Legend.Add();
chart.YAxis.MajorUnit = 10;
var series1 = chart.Series.Add(Chartsheet.Cells["L23:Q23"], Chartsheet.Cells["L22:Q22"]);
series1.HeaderAddress = new ExcelAddress("'Graphs'!K23");
var series2 = chart.Series.Add(Chartsheet.Cells["L24:Q24"], Chartsheet.Cells["L22:Q22"]);
series2.HeaderAddress = new ExcelAddress("'Graphs'!K24");
chart.Legend.Position = eLegendPosition.Bottom;
chart.YAxis.LabelPosition = eTickLabelPosition.NextTo;
chart.XAxis.MajorTickMark = eAxisTickMark.Out;
chart.XAxis.MinorTickMark = eAxisTickMark.None;
chart.ShowDataLabelsOverMaximum = true;
so i just forced a format of a barchart and i have the label option
var chart = (OfficeOpenXml.Drawing.Chart.ExcelBarChart) Chartsheet.Drawings.AddChart("chart", eChartType.ColumnStacked);
How to set Custom Menu Field values in Rightnow API of Oracle ?
I have a Custom field of data type Menu like :
Custom field Name : user type
Data Type : Menu
Value can be : Free, Paid or Premium
Can any one send me the java code by solving this problem?
Thanks in Advance
The following link is from the Oracle Service Cloud developer documentation. It has an example of setting a contact custom field using Java and Axis2, which would likely give you most of the information that you need in order to set your custom field.
At a high level, you must create an Incident object and specific the ID of the incident that you want to update. Then, you must create the custom field object structure using generic objects (because each site can have its own unique custom fields). Ultimately, your SOAP envelope will contain the node structure that you build through your java code. Since you're trying to set a menu, the end result is that your custom field is a NamedID object. You'll set the lookup name of the menu to one of the three values that you give above.
I'm a C# guy myself, so my example is in C#, but it should be easy to port to Java using the link above as an example too.
public static void SetMenuTest()
{
Incident incident = new Incident();
incident.ID = new ID();
incident.ID.id = 1234;
incident.ID.idSpecified = true;
GenericField customField = new GenericField();
customField.name = "user_type";
customField.dataType = DataTypeEnum.NAMED_ID;
customField.dataTypeSpecified = true;
customField.DataValue = new DataValue();
customField.DataValue.Items = new object[1];
customField.DataValue.ItemsElementName = new ItemsChoiceType[18]; //18 is a named ID value. Inspect ItemChoiceTypes for values.
customField.DataValue.Items[0] = "Free"; //Or Paid, or Premium
customField.DataValue.ItemsElementName[0] = ItemsChoiceType.NamedIDValue;
GenericObject customFieldsc = new GenericObject();
customFieldsc.GenericFields = new GenericField[1];
customFieldsc.GenericFields[0] = customField;
customFieldsc.ObjectType = new RNObjectType();
customFieldsc.ObjectType.TypeName = "IncidentCustomFieldsc";
GenericField cField = new GenericField();
cField.name = "c";
cField.dataType = DataTypeEnum.OBJECT;
cField.dataTypeSpecified = true;
cField.DataValue = new DataValue();
cField.DataValue.Items = new object[1];
cField.DataValue.Items[0] = customFieldsc;
cField.DataValue.ItemsElementName = new ItemsChoiceType[1];
cField.DataValue.ItemsElementName[0] = ItemsChoiceType.ObjectValue;
incident.CustomFields = new GenericObject();
incident.CustomFields.GenericFields = new GenericField[1];
incident.CustomFields.GenericFields[0] = cField;
incident.CustomFields.ObjectType = new RNObjectType();
incident.CustomFields.ObjectType.TypeName = "IncidentCustomFields";

Example i want to set city picklist to "istanbul"
can i use a picklistproperty ?
Here is a similar question asked in SO: Setting BusinessEntity picklist value using CRM 4.0 webservice
Please note that to set a picklist property on an entity, you need to know the value of the picklist item you wish to choose. This value property is of type integer. You may need to look at the attribute schema from within CRM to get this value. Or alternatively if this customization is going to be installed in multiple organizations and you believe this value might change, then you may need to retrieve the attribute metadata and determine the correct item programmatically based on the name. (This 2nd solution is not ideal as the picklist 'name' could be updated and would therefore break your code).
PicklistProperty city = new PicklistProperty();
city.Name = "new_city";
city.Value = 23; // City Picklist Value for 'istanbul';
Prop.Add(city);
PicklistProperty city = new PicklistProperty();
city.Name = "new_city";
city.Value = new Picklist();
city.Value.Value = 23; // City Picklist Value for 'istanbul';
Then you can use 'city' to set your picklist.
in my database there are 3 tables
CustomerType
CusID
EventType
EventTypeID
CustomerEventType
CusID
EventTypeID
alt text http://img706.imageshack.us/img706/8806/inserevent.jpg
Dim db = new CustomerEventDataContext
Dim newEvent = new EventType
newEvent.EventTypeID = txtEventID.text
db.EventType.InsertOnSubmit(newEvent)
db.SubmitChanges()
'To select the last ID of event'
Dim lastEventID = (from e in db.EventType Select e.EventTypeID Order By EventTypeID Descending).first()
Dim chkbx As CheckBoxList = CType(form1.FindControl("CheckBoxList1"), CheckBoxList)
Dim newCustomerEventType = New CustomerEventType
Dim i As Integer
For i = 0 To chkbx.Items.Count - 1 Step i + 1
If (chkbx.Items(i).Selected) Then
newCustomerEventType.INTEVENTTYPEID = lastEventID
newCustomerEventType.INTSTUDENTTYPEID = chkbxStudentType.Items(i).Value
db.CustomerEventType.InsertOnSubmit(newCustomerEventType)
db.SubmitChanges()
End If
Next
It works fine when I checked only 1 Single ID of CustomerEventType from CheckBoxList1. It inserts data into EventType with ID 1 and CustomerEventType ID 1. However, when I checked both of them, the error message said
Cannot add an entity that already exists.
Any suggestions please? Thx in advance.
Did you change the EventID before you pressed the button again. To me it looks as you did not. This would result that the code tries to insert the event with the ID 1 into the database, although, it is already there.
Maybe try increasing the event ID automatically or check whether the event is alreay present before trying to insert it.
Edit:
OK, here is what I think you want to do ... if I understood it correctly (it's in C# as I am more fluent in that language - however you should be able to easily convert the algorithm to VB - so just take it as pseudo code):
var db = new CustomerEventDataContext();
var newEvent = db.EventTypeSingleOrDefault(x => x.EventTypeId == txtEventID.Text);
if (newEvent != null) {
newEvent = new EventType();
newEvent.EventTypeId = txtEventID.Text;
db.EventType.InsertOnSubmit();
}
var chkbx = (CheckBoxList) form1.FindControl("CheckBoxList1");
for (int i = 0; i < chkbx.Items.Count; i++) {
var value = chkbxStudentType.Items(i).Value;
if (db.CustomerEventTypes.SingleOrDefault(x => x.EventTypeId == newEvent.EventTypeId) != null) {
// item already exists
} else {
var newCustomerEventType = new CustomerEventType();
newCustomerEventType.INTEVENTTYPEID = newEvent.EventTypeId;
newCustomerEventType.INTSTUDENTTYPEID = value;
db.CustomerEventType.InsertOnSubmit(newCustomerEventType);
}
}
db.SubmitChanges();
Two things I noticed:
You were adding the new EventType and then selecting the last event type based upon the id. This may not result in the item you just added.
You do not have to call SubmitChanges after each InsertOnSubmit. The DataBaseContext implementaton holds the inserted objects for you and you can reference them. Then you do a single submit to commit all changes. Note, however, in some complex circumstances a separate SubmitChanges is necessary, but this is rarely the case.
