SharePoint Post back to work after clicking on export documents

For use below code in .ascx page automatically post back document download link

<script type="text/javascript" language="javascript">
    //sharepoint postback to work after clicking on export to pdf
    if (typeof (_spBodyOnLoadFunctionNames) != 'undefined' && _spBodyOnLoadFunctionNames != null) {
        _spBodyOnLoadFunctionNames.push("supressSubmitWraper");
    }
    function supressSubmitWraper() {
        _spSuppressFormOnSubmitWrapper = true;
    }
</script>

Generate .ascx.g.cs file manually for visual webpart

Here are the steps:

Ensure the Project’s, not the Solution’s, “Site URL” is set to a valid SharePoint URL. (Impressive dependency, to regenerate your designer code locally, you need to have a valid working reachable SharePoint url)

Right click on .ascx file, select Properties, and update the property “Custom Tool” to “SharePointWebPartCodeGenerator”.

Right click on the .ascx file and click Run Custom Tool. At this point, if the “SampleWebPart1.ascx.g.cs” is regenerated, your frustration is acceptable.

Open the project.csproj file in Notepad++ or other editor, find the line SampleWebPart1.ascx.g.cs
You should see something like this:

<Content Include=”SampleWebPart\SampleWebPart.ascx”>
<Generator>SharePointWebPartCodeGenerator</Generator><LastGenOutput>SampleWebPart1.ascx.g.cs</LastGenOutput>
</Content>

Change the LastGenOutput value to SampleWebPart.ascx.g.cs

Go back to Visual Studio 2012 and it asks to Reload the project (or Discard). 

Reload the project.

Right click on .ascx file and Run Custom Tool again.

Voila, the 1 is gone and the file should be now called SampleWebPart.ascx.g.cs.

In this Code I have Used one list "Employees"

In this List I have Created below fields

Full Name

Manager  ----Look-up of "Full Name"

Job Roles --- Look-up with another list

Org Unit --- Look-up with another list

After Creating List You can Deploy and add  web-part in Site-Page.

It will come  as below

Creating a custom WCF REST service for SharePoint 2013 without a Visual Studio template

• Create a new SharePoint 2013 Empty Project as a Farm Solution

• Add a WCF Service Application project to your solution

• Add the ISAPI mapped folder to your SharePoint project

• Drag the Service1.svc and Service1.svc.cs files from the WCF project to the SharePoint project under the ISAPI mapped folder

• Drag the IService1.cs file from the WCF project to the SharePoint project

• Add the WCF references to your SharePoint project

1. System.Runtime.Serialization
2. System.ServiceModel
3. System.ServiceModel.Web

• Change the namespace from MyService to your assembly's namespace (e.g., MyRestService) in Service1.svc.cs and IService1.cs

• Remove a WCF Service Application project to your solution

• Build your project

• Using the Visual Studio Command Prompt, go to the project output folder of the SharePoint project

sn -T MyRestService.dll

• In Service1.svc, change the Service attribute on the ServiceHost directive to be in the following format:

<%@ ServiceHost Language="C#" Debug="true" Service="{NameSpace}.{ServiceName}, {AssemblyName}, Version=1.0.0.0, Culture=Neutral, PublicKeyToken={PublicKeyToken}" CodeBehind="Service1.svc.cs" %>

Replace the tokens here, represented by {Token} with the appropriate values for your project. e.g.,

<%@ ServiceHost Language="C#" Debug="true" Service="MyRestService.Service1, MyRestService, Version=1.0.0.0, Culture=Neutral, PublicKeyToken=099213f2a077836f" CodeBehind="Service1.svc.cs" %>



• Deploy your solution
• Verify the service loads
• Note: see below for troubleshooting a common error.
• Add a HelloWorld operation to your contract, IService1.cs that is set up for REST.

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "HelloWorld")]
string HelloWorld();

• Implement the operation in Service1.svc.cs

public string HelloWorld()
{
    return "Hello World";

}

• Update web.config with the appropriate info for your service

 <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceServiceBehavior">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true">
          </serviceMetadata>
          <serviceDebug includeExceptionDetailInFaults="true">
          </serviceDebug>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="jsonBehaviour">
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <services>
      <service name="MyRestService.Service1" behaviorConfiguration="MyServiceServiceBehavior">
        <endpoint address="" binding="webHttpBinding" behaviorConfiguration="jsonBehaviour" contract="MyRestService.IService1">
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange">
        </endpoint>
      </service>
    </services>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true">
    </serviceHostingEnvironment>
  </system.serviceModel>

Test your HelloWorld operation and you should see the following:

http://win-0n4jtsv8137/_vti_bin/Service1.svc/HelloWorld

If you want to use multiple services for same solution you can add Service Details in web config file like below

<services> <service name="LeaveManagementSystem.LMSService" behaviorConfiguration="LMSServiceServiceBehavior"> <endpoint address="" binding="webHttpBinding" behaviorConfiguration="jsonBehaviour" contract="LeaveManagementSystem.LMSIService"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"> </endpoint> </service> <service name="MyRestService.Service1" behaviorConfiguration="LMSServiceServiceBehavior"> <endpoint address="" binding="webHttpBinding" behaviorConfiguration="jsonBehaviour" contract="MyRestService.IService1"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"> </endpoint> </service> </services>

• If you want to pass values through WCF Service

you can write Below code in IService.cs

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "Types")]

List<Types> Types();


[DataContract]
    public class Types
    {
        [DataMember]
        public int ID { get; set; }

        [DataMember]
        public string Title { get; set; }

    }

you can write Below code in Service.svc.cs

List<Types> IService.Types()
        {
            var resultTypes = new List<Types>();
            DataTable dtType = objLMS.GetType();

            resultLeaveTypes = (from DataRow row in dtType.Rows
                                select new Types
                                {
                                    ID = Convert.ToInt32(row["ID"]),
                                    Title = Convert.ToString(row["Title"])

                                }).ToList();

            return resultTypes;

        }

• If you want to get values From WCF Service

you can write Below code in IService.cs

[OperationContract]

[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "ApplyforLeave?Leavetype={Leavetype}&FromDate={FromDate}&ToDate={ToDate}&Duration={Duration}&PhoneNumber={PhoneNumber}&Reason={Reason}")]

void ApplyforLeave(Int32 Leavetype, DateTime FromDate, DateTime ToDate, Int32 Duration, String PhoneNumber, String Reason);

you can write Below code in Service.svc.cs

public void ApplyforLeave(int Leavetype, DateTime FromDate, DateTime ToDate, int Duration, string PhoneNumber, string Reason) {

return "Your value is " + Convert.ToString(Leavetype) + " FromDate is " + Convert.ToString(FromDate) + " ToDate is " + Convert.ToString(ToDate) + " Duration is " + Convert.ToString(Duration) + " PhoneNumber is " + PhoneNumber + " Reason is " + Reason;

}
