I have a requirement to show the validation message for language checkbox if no language is selected. I have used below code. It shows the alert message box but closes the workflow window. Is there a way to show alert message on top of the Worflow window?
class ValidateItem
{
public void Process(WorkflowPipelineArgs args)
{
Assert.ArgumentNotNull(args, "args");
if (args.DataItem == null)
return;
using (new SecurityDisabler())
{
//check if a valid option is selected in the dropdown
if (args.CommentFields["Select Items"] != null && args.CommentFields["Select Items"].Equals(""))
{
SheerResponse.Alert("Please select a valid option in the 'Select Items' field");
args.AbortPipeline();
return;
}
if (args.CommentFields["Languages"] != null && args.CommentFields["Languages"].Equals(""))
{
SheerResponse.Confirm("Please select at least one language");
SheerResponse.SetReturnValue("failed");
args.AbortPipeline();
return;
}
//Don't do validation for child items in case of branch and artilce approval
foreach (var obj in args.Parameters)
{
var type = obj.GetType();
if (type == typeof(Dictionary<string, string>))
{
var dictionary = (Dictionary<string, string>)obj;
string doValidation;
dictionary.TryGetValue("DoValidation", out doValidation);
if (doValidation == "false") return;
}
}
//check if item is not already locked by someone other than the current user.
//ID for list item 'Single Item' in the dropdown
//added null check for CommentFields in case workflow is executed through SRM
if (args.CommentFields["Select Items"] != null && !args.CommentFields["Select Items"].Equals(ItemIds.MaginetPublishingWF.ApprovalOption.SingleItemApproval)
&& args.DataItem.Locking.IsLocked() && args.DataItem.Locking.GetOwner().ToLowerInvariant() != Sitecore.Context.User.DisplayName.ToLowerInvariant())
{
SheerResponse.Alert("Cannot fast approve '" + args.DataItem.DisplayName + "' as it is locked by another user(" + args.DataItem.Locking.GetOwnerWithoutDomain() + ").", new string[0]);
args.AbortPipeline();
return;
}
//Read item presentation details, validation for related data source content item with at least one version in approve state
if (!args.CommentFields["Select Items"].Equals(ItemIds.MaginetPublishingWF.ApprovalOption.BranchApproval))
{
var renderings = ItemUtils.GetItemRenderings(args.DataItem);
bool relatedDSInDraft = true;
foreach (var rd in renderings)
{
Item dataSource = ItemUtils.GetDataSourceItem(rd.Datasource, args.DataItem);
if (dataSource != null && dataSource.IsBasedOnTemplate(TemplateIds.PageTemplate))
{
foreach (var versionItem in dataSource.Versions.GetVersions())
{
IWorkflow versionItemWorkflow = versionItem.Database.WorkflowProvider.GetWorkflow(versionItem);
if (versionItemWorkflow != null)
{
WorkflowState parentWorkflowState = versionItemWorkflow.GetState(versionItem);
if (parentWorkflowState.StateID == ItemIds.MaginetPublishingWF.State.ApprovedState)
{
relatedDSInDraft = false;
break;
}
}
else
{
relatedDSInDraft = false;
}
}
if (relatedDSInDraft)
{
SheerResponse.Alert("Cannot fast approve '" + args.DataItem.DisplayName + "' becasue for '" + dataSource.Paths.FullPath + "' data source item there is no approved item version'", new string[0]);
args.AbortPipeline();
return;
}
}
}
}
if (args.DataItem.Paths.IsContentItem)
{
//validation for parent item
Item parentItem = args.DataItem.Parent;
if (parentItem != null)
{
IWorkflow argsWorkflow = args.DataItem.Database.WorkflowProvider.GetWorkflow(args.DataItem);
if (argsWorkflow != null)
{
WorkflowState argsWorkflowState = argsWorkflow.GetState(args.DataItem);
while (parentItem.TemplateID != TemplateIds.Site)
{
IWorkflow parentWorkflow = parentItem.Database.WorkflowProvider.GetWorkflow(parentItem);
if (parentWorkflow != null && parentItem.Fields[FieldIDs.DefaultWorkflow].Value == ItemIds.MaginetPublishingWF.WorkflowID)
{
WorkflowState parentWorkflowState = parentWorkflow.GetState(parentItem);
if (parentItem.Versions.Count == 1 && parentWorkflowState.StateID == argsWorkflowState.StateID)
{
SheerResponse.Alert("Cannot fast approve '" + args.DataItem.DisplayName + "' as '" + parentItem.DisplayName + "' is not approved", new string[0]);
args.AbortPipeline();
return;
}
}
parentItem = parentItem.Parent;
}
}
}
}
}
}
}
}
