CRM 2011 Get OptionSetValue Value through Label

Sometimes we want to be able to get the OptionSetValue value from the label itself. One way is to use the metadata request and loop through it but this is a cumbersome way.

The easier way is to put those OptionSetValue data into an enum like this:
?
1
2
3
4
5
6
7
8
9
10
11
12
13
public enum Approach
{
    [Description("Value Marketing")]
    ValueMarketing = 100000000,
    [Description("Communications & Events")]
    CommEvents = 100000001,
    [Description("Investigate")]
    Investigate = 100000002,
    [Description("Key Account Management")]
    KeyAccManagement = 100000003,
    [Description("Pro-Active Price & Product")]
    ProActivePriceProduct = 100000004
}


We use Description Attribute for the Label so that it supports string format.

Then we use this helper method:
?
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
public static class EnumHelper
{
    public static T GetValueFromDescription<t>(string description)
    {
        var type = typeof(T);
        if (!type.IsEnum) throw new InvalidOperationException();
        foreach (var field in type.GetFields())
        {
            var attribute = Attribute.GetCustomAttribute(field,
                typeof(DescriptionAttribute)) as DescriptionAttribute;
            if (attribute != null)
            {
                if (attribute.Description == description)
                    return (T)field.GetValue(null);
            }
            else
            {
                if (field.Name == description)
                    return (T)field.GetValue(null);
            }
        }
        throw new ArgumentException("Not found.", "description");
    }
}


And there you go. You can easily get the value like this:

?
1
2
3
new_entity entity = new new_entity();
 
entity.new_approach = new OptionSetValue((int)EnumHelper.GetValueFromDescription<OptionSet.Approach>("Value Marketing"));


Hope this helps,
Andreas

SharePoint 2013 anonymous access add attachments to list item

Image
Hi, Sometimes you want to enable anonymous access to be able to add a list item but at the same time attaching some documents. After good few hours playing around trying to make this work, turns out that we can achieve this functionality. The trick is to use RunWithElevatedPrivileges method for the file upload. We also want the file upload functionality to be available on the NewForm.aspx as it wouldn't make sense to put it in other forms as any user would be able to upload files to other records. The result will be something like this: When it is saved, the user is redirected to the display form: The close button then will take the user back to the homepage (or any page you desire) The steps: 1. Create an ascx control to host your file upload control in your project.  Put the below script in the ascx as well (credit to this post ): The code behind: 2. Create custom form template. You have to put the ascx in the CONTROLTEMPLATES folder of the ...

CRM Plugin - Parent and Child Pipeline

This concept tends to confuse people often - and I was no exception. I came across this problem when trying to create custom auto-numbering for one of my projects. Creating auto-number for Opportunity is easy. This is because the user creates opportunity straight from the home screen - thus the plugin runs on parent pipeline. However, it's a different story if you are dealing with Quote entity. Quote can be created in 2 ways, through the home screen OR the opportunity screen. If you create it from the latter, it will run on the child pipeline and you will find that your plugin will not work. Registering it as a child pipeline is easy, but CRM makes it harder since you can't use ICRMService. Instead, you have to create CRMService manually by using this piece of code: Not only that, with the child plugin you can't use Query expression to fetch other entities in your code unless you register it as ASYNCHRONOUS plugin. Mark Kovalcson in his blog found out that: A C...
