RadGrid - Export to Excel with Custom Currency Format

A couple days ago, I had a requirement from client that is they want to export to excel from RadGrid with the currency format is "$ xxx.xx USD" (may be it's negative value), moreover, in that excel file, they can calculate their fields. After googling on 2-day I had no result although I tried to ask the question on telerik forum at here and also stackoverflow.
Luckily, based on some suggestions on both 2 site, I solved this problem (phew, God bless me)

Below is all steps to get it (I assumed we can format "$ xxx.xx USD" on grid)

Step 1:
Register the ExcelExportCellFormatting event for grid

protected void grid_ExcelExportCellFormatting(object source, ExcelExportCellFormattingEventArgs e)
{
     var item = e.Cell.Parent as GridDataItem;
     var hdfCurrency = item.FindControl("hdfCurrency") as HiddenField;

     var format = FormatCurrencyWhenExportToExcel(hdfCurrency.Value);

     switch (e.FormattedColumn.UniqueName)
     {
          case "TotalPrice":
              var hdfTotalPrice = item.FindControl("hdfTotalPrice") as HiddenField;

              // Assumption the hdfTotalPrice.Value = "25.00" or "-25.00";

              e.Cell.Text = hdfTotalPrice.Value;
              e.Cell.Style["mso-number-format"] = format;
              break;
     }
}

Step 2:
Write the FormatCurrencyWhenExportToExcel function

public static string FormatCurrencyWhenExportToExcel(string currency)
{
       var regionInfo = new System.Globalization.RegionInfo(Globals.GetCurrencyCulture(currency).Name);
       var format = @"\0022" + regionInfo.CurrencySymbol + @"\0022\#\,\#\#0\.00\ \0022" + regionInfo.ISOCurrencySymbol + @"\0022";
       return format;
}

That's all.

Enjoy your code.

Searching special character (e.g. %,_) with .NET and Stored Procedure

Today, I spent 2 hours to searching the way to search with "%,_" characters. When my QC fill these characters on search textbox, it has shown all items. How a stupid I am!! :D

Finally, I found the way to fix it. It's quite simple. Below is the steps

Assumption, your text search is "%" (I named it is searchText variable)

          searchText = searchText .Replace("%","[%]"); //same with "_" character

It works right way....

For more information you can see "WildCard Characters" section in this page

LIKE '5[%]' = 5%
LIKE '[_]n' = _n
LIKE '[a-cdf]' = a, b, c, d, or f
LIKE '[-acdf]' = -, a, c, d, or f
LIKE '[ [ ]' = [
LIKE ']' = ]
LIKE 'abc[_]d%' = abc_d and abc_de
LIKE 'abc[def]' = abcd, abce, and abcf

How to add a Uninstall option in Visual Studio Setup project without writing code

1) In the Setup Project –> File System windows –> Right Click “File System on Target machine” –> add a Special Folder, select System Folder;

2) Into this system folder Add a file. Browse for msiexec.exe from local System32 folder and add it. Override default properties of this file as follows:

Condition:=Not Installed (make sure you put ‘Not Installed’ exactly like that, same case and everything), Permanent:=True, System:=True, Transitive:=True, Vital:=False.

3) Create a new shortcut under the ‘Users Program Menu’, Set Target to the System Folder which you created in the step 1. and point it’s at the msiexec.exe. Rename the shortcut to ‘Uninstall Your Application’. Set the Arguments property to /x{space}[ProductCode].

4) Build the project, ignore warning about the fact that msiexec should be excluded, DONT exclude it or the setup project wont build.

The ‘Not Installed’ condition and Permananet:=True ensure that the msiexec.exe is only placed into the system folder as part of the install IF it doesn’t aready exist, and it is not removed on an uninstall - therefore it;s pretty safe to ignore that warning and just go for it.

Solving RAW issue with WCF and content-type

A couple days ago, I faced an issue when posting content with content-type:text/xml. The error which I received is "The expected body format value is 'RAW'". Around the google I found some topic discuss my issue. Follow by these posts, I solved my issue. Thanks God, it take me 3 hours.

1 - WCF "RAW" programming model (Web) - receiving arbitrary data

2 - WebContentFormat.Raw in your WCF config file

In the 1st link, it just tell me how to implement the WebContentFormat extension. Beside, the 2nd link tell me how to config it in Web.config

Below is my implement (have some differences)

1 - I defined the new class which was named RawContentTypeMapper inherit from WebContentTypeMapper. This class will change the any content-type to RAW

1 using System.ServiceModel.Channels;

2

3 namespace AtlanticGateway.GatewayComponent

4 {

5 public class RawContentTypeMapper : WebContentTypeMapper

6 {

7 public override WebContentFormat GetMessageFormatForContentType(string contentType)

8 {

9 if (contentType.Contains("text/xml") || contentType.Contains("application/xml"))

10 {

11 return WebContentFormat.Raw;

12 }

13 else

14 {

15 return WebContentFormat.Default;

16 }

17 }

18 }

19 }

2 - Reference this new WebContentTypeMapper in your config file in customBinding:

25 <service behaviorConfiguration="NotificationServiceBehavior"

26 name="AtlanticGateway.GatewayComponent.Services.NotificationService">

27 <endpoint behaviorConfiguration="web" binding="customBinding" bindingConfiguration="RawReceiveCapable"

28 contract="AtlanticGateway.GatewayComponent.Message.INotificationService" />

29

74 <bindings>

75 <customBinding>

76 <binding name="RawReceiveCapable">

77

78 <webMessageEncoding webContentTypeMapperType=

79 "AtlanticGateway.GatewayComponent.RawContentTypeMapper, AtlanticGateway.GatewayComponent,

80 Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />

81 <httpTransport manualAddressing="true" maxReceivedMessageSize="524288000"

82 transferMode="Streamed" />

83

84

That's all.

Thanks David and CarlosFigueira
