Introduction
Sometimes you want to create a Task Item in SharePoint for a Client Event in a process. The functionality of having a Client Event with a matching SharePoint Server Task List Item is currently only available in the InfoPath wizards. This article describes how to combine a Default Client event and a SharePoint 2003 List event.
Configuring SharePointConfigure an SPS list by adding a Hyperlink column called Task Link. This Task Link column will be used in K2 to point to the Client Event web page. Configuring K2.net Studio | |
| 1. | Add an Activity to your process |
| 2. | Set up a Destination Rule for the new activity |
| 3. | Add an Integer data field on the process level called ListItemID This data field will be used to store the newly created list item identifier so that it can be removed again. |
| 4. | Insert a Default Client event into this activity |
| 5. | Open the Event Item property page for Default Client |
| 6. | Uncheck Client Side Code, and click Ok on the warning message |
| 7. | Check Internet and configure it to point to your ASP page |
| 8. | Check SMTP Notification and configure it with a message for the user |
| 9. | Click Generate Code and click Ok on the warning message |
| 10. | Select Use Code |
| 11. | Click Edit Code |
| 12. | The client event code window will now open in the main view |
| 13. | Download the zip file and open the SPSListFunction_VB.txt for VB.NET or SPSListFunction_CS.txt for CSharp file |
| 14. | Insert -== A ==- at the top of the Sub Main function |
| try { SPSListFunction(K2); } catch (System.Exception ex) { throw new System.Exception(ex.Message); } | |
| 15. | Append -== B ==- at the end of the client side code |
| private void SPSListFunction(ClientEventContext K2) { // Set up variables string Temp, ErrorMessage = ""; System.Int32 TempInt = 0; System.Int32 ListItemId = 0; //-=1=- Replace with your Client Event Page string strURL = "http://localhost/Samples/ClientEvent.aspx?sn={SERIALNO}"; strURL = strURL.Replace("{SERIALNO}",K2.SerialNumber); //-=2=- Replace with your SPS Server string Server = "http://w2003:8080"; if (! (Server.EndsWith("/"))) Server + = "/"; //-=3=- Replace with your site name string Site = "sites/SPS"; if (! (Site.EndsWith("/") && Site.Trim() != "")) Site += "/"; //-=3.2=- Replace with your task list name string ListName = "Tasks"; //-=4=- Replace with your domain. // This would be the domain that you specify when signing on // e.g. DomainUsername string Domain = "YourDomain"; K2SPSList SpsList = new K2SPSList(); // Set Url for Web Service SpsList.Url = Server + "_vti_bin/K2SpsList.asmx"; // Set Credentials SourceCode.K2SPUtilities.SPSUtilities SpsUtils = new SourceCode.K2SPUtilities.SPSUtilities(); SpsList.Credentials = SpsUtils.GetCredentials(Server); // Field Values object[] Field = new object[4]; // FieldDesc used for URL Fields object[] FieldDesc = new object[4]; for (int i = 0; i < = 3; i++) { Field[i] = ""; FieldDesc[i] = ""; } //-=5=- Replace these values with your values. //Look at the field mapping in the strXML assignment //You can add more fields by increasing/descreasing the //size of the array and adding to the //xml list. Field[0] = "Document Approval"; Field[1] = Domain + "\" + K2.ActivityInstanceDestination.User; Field[2] = "This is a description for your task item"; Field[3] = strURL; FieldDesc[3] = "Task Link"; // Build the Xml string strXml; strXml = ""; strXml += "" + Field[0].ToString() + ""; strXml += "" + Field[1].ToString() + ""; strXml += "" + Field[2].ToString() + ""; strXml += "" + Field[3].ToString() + " "; strXml += " "; // Call Web Service to check out Document ErrorMessage = ""; if (!(SpsList.CreateListItem(Site, ListName, strXml, ref ListItemId, ref ErrorMessage) )) { // Error Occurred in CreateListItem - Raise Error throw new System.Exception(ErrorMessage); } // Store the return value for the newly created ListItem K2.ProcessInstance.DataFields["ListItemID"].Value = ListItemId.ToString(); } | |
| 16. | Follow step -=1=- to -=5=- inside the SPSListFunction function |
| 17. | Save the code, export and test the process |
| Further SuggestionsYou could create a code module and call this shared function where ever you need to integrate a client event with a SPS task list | |
