Description
Hi, Today I am going to explain about assigning multiple users to a workflow task in SharePoint. Our requirement is dynamically create the tasks and assign to multiple users in SharePoint visual studio workflows.
Step 1:
To create an Empty SharePoint Project
Click Next Button
Select Target List and Task List name , then Click Next Button and Then Finish Button
After Click finish button We will get screen like This
Step 2:
Go to the Toolbox Select Replicator and drag , by using replicator we will loop the assign users list
Then select Sequence activity and drag inside the Replicator
Next Select the Create Task and drag the inside sequence activity for creating each user items inside the task list
Step 3:
Select the Replicator activity and right click then select properties .Select InitialChildData then click the ellipsis button (…).
In the Choose the type of member to create option list, click Create Field. Click OK.
Check ExecutionType and then Select Parallel(Based on Requirement)
Enter the Initilized Method Name
Next Select the UntilCondition Column as a Code Condition
And then write the CodeCondition Method Name
Select the Create Task activity and right click then select properties. Write the CorelationToken Name
Select The OwerActivity Name
Select the TaskId And Task Properties
And then Write Method Invoking Method name
Step 4:
Go to the Toolbox Select While Activity and drag
Select the While activity and right click then select properties.And then Check condition and Select code Condition Method
Go to the Toolbox Select OntaskChange Activity and drag
Select theOnTaskChange activity and right click then select properties and Select Corelation Token and Task Id
Next Select The AfterProperties
And then write the Invoked method
Select the OnWorkflow Activity and Duble Click
Step 5:
Total Code Here
[c-sharp]
public sealed partial class CreateMultiUserTask : SequentialWorkflowActivity
{
public CreateMultiUserTask()
{
InitializeComponent();
}
public Guid workflowId = default(System.Guid);
public SPWorkflowActivationProperties workflowProperties = new SPWorkflowActivationProperties();
public Guid createTask1_TaskId1 = default(System.Guid);
public SPWorkflowTaskProperties createTask1_TaskProperties1 = new Microsoft.SharePoint.Workflow.SPWorkflowTaskProperties();
public int count = 0;
//For craete the Multiple Tasks
private void CreateTaskMethod(object sender, EventArgs e)
{
createTask1_TaskId1 = Guid.NewGuid();
createTask1_TaskProperties1.Title = "Relipcator";
createTask1_TaskProperties1.AssignedTo = replicatorActivity1.InitialChildData[count].ToString();
count++;
}
public bool isfin = false;
// Check the on task chenge Condition
private void IfMultiUserApprove(object sender, ConditionalEventArgs e)
{
if (onTaskChanged1_AfterProperties1.PercentComplete == 1.0)
{
e.Result = true;
}
else
{
e.Result = false;
}
}
public SPWorkflowTaskProperties onTaskChanged1_AfterProperties1 = new Microsoft.SharePoint.Workflow.SPWorkflowTaskProperties();
private void OnTaskChange(object sender, ExternalDataEventArgs e)
{
onTaskChanged1_AfterProperties1 = onTaskChanged1.AfterProperties;
}
// end of the task chenge Condition
public IList replicatorActivity1_InitialChildData1 = default(System.Collections.IList);
public IList assignees = default(System.Collections.IList);
//replecator Method
private void ReplecatorMethod(object sender, EventArgs e)
{
replicatorActivity1.InitialChildData = assignees;
}
private void ReplicatorCodition(object sender, ConditionalEventArgs e)
{
e.Result = !(count < assignees.Count);
}
// End of the replecator
//workflow Acctivity method
private void onWorkflowActivated1_Invoked(object sender, ExternalDataEventArgs e)
{
workflowId = new Guid();
assignees = new ArrayList();
string assigner = string.Empty;
string multiusers = string.Empty;
string user = string.Empty;
char[] to_splitter = { ';' };
string to_list = Convert.ToString(workflowProperties.Item["TR_Assigndto"]); // Reads value stored in SPList. (i.e., "Domain\User1; Domain\User2")
string[] arr = to_list.Split(to_splitter);
ArrayList entityArrayList = new ArrayList();
for (int i = 0; i < arr.Length; i++)
{
if (i != 0 && (i % 2) == 0)
{
user = arr[i].Substring(arr[i].IndexOf("#") + 1);
assignees.Add(workflowProperties.Web.SiteUsers.GetByID(int.Parse(user)).LoginName);
}
else if (i == 0)
{
user = arr[i];
assignees.Add(workflowProperties.Web.SiteUsers.GetByID(int.Parse(user)).LoginName);
}
}
count = 0;
}
// end of the workflow Acctivity method
}

And then Deploy the solution
Step 6:
Go to the sharepoint site and add the item into the sharepoint list
Now Go to the task list to check the How many tasks are created based on previous enter users snap
- Start Visual Studio 2012 in administrator mode.
- On the File menu, point to New, and then click Project. If Visual Studio is set to use Visual c# development,settings, on the File menu, click New Project.
- In the New Project dialog box, select the SharePoint Soluction node.
- In the Templates pane, select Empty SharePoint Project.
- Then in that soluction Add new item Select Sequential Work Flow For the name of the project, type CreteMultiuserTask, and then click OK.
