jGrid and ASP.Net web forms

leave a comment »

Ok, so you have some fancy app and you decided to make it more fancy by using jGrid. Good idea!, but where to start ? I get to that point around week ago and took me a while to find proper resources how to do it. Here is short guide how to go straight to the point where you will be ready to use this magic component.

1. Start, by going to page Trirad download page and download entire packed by marking all checkboxes and hitting download button.

Once you get the zip file, then unpack it. We are going to need few thinks from it:


  • get all *.js files from the “js” directory and place them in your “script” folder in your visual studio project
  • get into “i18n” folder and get the file with respond to your language (or the one you want to use in your app). In my case it was “grid.locale-pl.js” for polish

this should give you something like this (for “Script” folder):


Notice : please note that there is additional file there “jquery-1.8.1-ui.min.js” with is not part of jgrid, but it is there as I’m using it in the app)

2. We need a theme for our grid. Please go to jqueryUI page , find your favorite theme in gallery and download it.

Once you get zip file then unpack it. We are going to get from it “css” folder:


Notice: Please note here that name of the “theme” folder inside “css” will be different as it depend on the theme you picked up. In my case I decided to use “redmond” theme so this is how I get “redmond” folder name.

Copy that "redmond” folder to your project:


3. Put jGrid on the aspx form

  • place all necessary link to jgrid resources:


  • put page place holders to store jgrid content


This is the place where the jGrid will be drawn by JavaScript.

  • put jgrid creation script block


here is few important peaces:

url <- this is address of our asmx web service with will feed our grid with data. How to build it to return proper format will be shown in an minute

mtype = post <- our parameters will be passed in content of the message (instead in query string)

contentType = “xml” <- this tells jGrid what will be returned format of data , so he can consume them properly. There is also option of returning json format but for some reason I didn’t manage to force asmx service to return data in that format (I believe that main reason of that is that jgrid is not sending parameters i json format with is causing that asmx do not want to use json to return data)

data <- parameters with we are sending to asmx

colNames, colModel <- defines list of columns in our gird.

4. Build asmx web service to provide data for our grid

Go and new web service to your project:


Notice : remember to change name to “Analizy.asmx” <- as this is the name of service we used in definition of jGrid URL)

remove all what is inside namespace brackets and past this peace of code:

   1:      [WebService(Namespace = "http://tempuri.org/")]
   2:      [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
   3:      [ScriptService]
   4:      public class Analizy : System.Web.Services.WebService
   5:      {
   7:          [WebMethod]
   8:          public rows GridData(string sidx, string sord, int page, int rows)
   9:          {
  11:              int pageIndex = Convert.ToInt32(page);
  12:              int pageSize = rows;
  14:              return
  15:                  new rows(20, pageIndex, 200);
  16:          }
  17:      }
  19:      public class rows
  20:      {
  21:          public int total { get; set; }
  22:          public int page { get; set; }
  23:          public int records { get; set; }
  24:          public row[] gridEntires { get; set; }
  26:          public rows() { }
  28:          public rows(int totalPages, int currentPage, int totalRecords)
  29:          {
  30:              List<row> entries = new List<row>();
  31:              for (int i = 0; i < totalRecords; i++)
  32:                  entries.Add(new row(i, DateTime.Now.ToString("yyyyMMdd") , "1", "1", "1"));
  34:              this.gridEntires = entries.ToArray();
  36:              this.total = totalPages;
  37:              this.page = currentPage;
  38:              this.records = totalRecords;
  40:          }
  41:      }
  43:      public class row
  44:      {
  45:          [XmlAttribute]        
  46:          public string id { get; set; }
  48:          [XmlElement(ElementName="cell")]
  49:          public string[] cell;
  51:          public row() {}
  53:          public row(int ID, string Data, string Zm, string Stanowisko, string Linia)
  54:          {
  55:              cell = new string[5];
  57:              this.id = ID.ToString();
  58:              cell[0] = ID.ToString();
  59:              cell[1] = Data;
  60:              cell[2] = Zm;
  61:              cell[3] = Stanowisko;
  62:              cell[4] = Linia;
  63:          }
  65:      }

.csharpcode, .csharpcode pre
font-size: small;
color: black;
font-family: consolas, “Courier New”, courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
background-color: #f4f4f4;
width: 100%;
margin: 0em;
.csharpcode .lnum { color: #606060; }

Classes “rows” and “row” create structure with once it is serialized then it conform to the xml structure required by jGrid component (line 45, 48 are quite important).

You first demo is ready! This should let you have a good starting point to tweak it up for your needs.

6648 Orphaned DTA Service Instances in {Server}.BizTalkDTADb, 1 Messages with refcount less than 0 in {Server}.BizTalkMsgBoxDb [SQLSTATE 42000] (Error 50000)

leave a comment »

My dear BizTalk 2010. I’ve just installed you and placed really simply app… why you are screaming with this nasty error ?

Actually not BizTalk itself is doing that but rather one of his SQL jobs :

Monitor BizTalk Server
Scans for any known issues with the BizTalkMgmtDb, BizTalkMsgBoxDb, and BizTalkDTADb databases. This includes orphaned instances.
Note This job is created on BizTalk Server 2010.

After digging for a while I found a good post describing what to do with that. The idea is to use special tool called “BizTalk Terminator”.

As you can find in description of mentioned post this tools is mentioned to resolve one of common database integration problem. In the old days those tasks where performed manually. Lucky now… we can just start that tool and use it.

Here are steps to use mentioned terminator:

  • Do backup of entire environment. In my case I was lucky that we are running BizTalk on VM host, so I’ve just asked to create snapshot of the entire machine
  • Determine task in “BizTalk Terminator” to run in order to resolve problem. In case of our issue the problem should be resolved by task:


  • Shutdown BizTalk instance and all his SQL jobs (make sure that they are not running)
  • Open “Terminator” , specify server name and database information
  • Check all checkboxes in order to confirm that you did backup and stop all instances and SQL jobs
  • Find task “Repair Refcounts for All Messages” and execute it (no parameters is required)



  • Find task “Repair Orphaned DTA Service Instances” and execute it (no parameters are required)



After performing above steps I did run SQL job “Monitor BizTalk Server” and confirmed that problem was resolved.

good luck…

SharePoint vs File share

leave a comment »

I’ve seen today great session around “Complete Enterprise Content Managment in Microsoft SharePoint 2010” and one quite interesting subject was around SharePoint vs File share and when to go for one of those. Here are some summary from out the guidance slide:

Use SharePoint when:

  • You need version tracking
  • There is a need for collaboration
  • You need flexible security model
  • All users have access to SharePoint
  • You need to describe the file using metadata
  • You have compliance requirements that can’t be met with file shares
  • File sizes are smaller then 75Mb

From above I would say that key points are “needs for versioning” and “needs for describing files with metadata”. In my experiences those two were the ones with help me to answer a question if migrating current “Files shares” to SharePoint is right choice. If business need to version document then SharePoint is a great answer as this saves users from changing names of the files each time they change something and prevents from two people to work on the some document at the some time.

Use a File Share when:

  • File sizes are more then 75Mb
  • You need a rigid security model
  • The File have a client-server usage profile
  • Files are archive, data dumps or backups or do not change much (option here is to go for RBS)
  • Files need to be locally available

In my experience I would say that we should go for File shares in case we can not (or shouldn’t go for SharePoint). In addition from the above list I would pick up “needs to for client-server usage” (in that case this could requires rewriting some soft to use SharePoint storage), “need to keep archive, backup files…”. Size of the file should also be taken into consideration as quite big files can quite quickly kill SharePoint storage/DB.

I really encourage you to watch this entire session as there was more pros and cons described when deploying SharePoint into organization.
