I have a usercontrol with an update panel which displays filtered product information. Some of the values are created in Umbraco using the Textstring array. Below is a the generated xml for the Textstring Array:
As I'm displaying other properties on the page I've created a node object and have been using the GetProperty method. This is fine for the product name etc... But I not usre if I can use the same approach with the Textstring Array.
Code extract:
var node = new Node(Convert.ToInt16(ddl.SelectedValue));//Selected node ID via drop down menu on web site page //display other property valuse //.. string aerValues = node.GetProperty("previousAERRates").Value; //Iterate over value pairs and display on page
Would be grateful if someone could advise on how I can get the XML so that I can display each set of values in the update panel.
Which version of uComponents and which type of Razor are you using? (e.g. macroScript or MVC/partial)
For the Razor macroScripts we have a custom model-binder that should be used automatically, this should give you the value as an List<string[]> object type. You can loop over that accordingly.
With MVC Razor, we have a PropertyEditorValueConverter that will do the same thing, but it's only available in uComponents v6+ (supports Umbraco 6.1+)
Since you also have 2 values in your Textstring Array you could use something like this:
private IEnumerable<ProductProperty> GetProperties(IPublishedContent content)
{
var xml = content.GetPropertyValue<XElement>("properties");
if (xml == null)
{
return Enumerable.Empty<ProductProperty>();
}
var properties =
(
from x in xml.Descendants("values")
let elements = x.Elements()
select new ProductProperty()
{
Text = elements.ElementAt(0).Value,
Value = elements.ElementAt(1).Value
}
);
return properties;
}
Sorry, I'm using Umbraco 4.11.10 and uComponents 5.5.0. So have a usecontrol in a webform and then using the code behind to display the various property values. With this version could you advise on the references that I need to add to the usercontrol project.
Jeroen - thanks for your solution, will give this a try if I can't access the custom model-binder that lee mentioned.
Once you get back the value from node.GetProperty("previousAERRates").Value you should have an XML string. You could then pass it to a function that will return you something more usable.
var values = new List<string[]>();
if (!string.IsNullOrEmpty(yourValueFromPreviousAERRates))
{
var xml = new XmlDocument();
xml.LoadXml(yourValueFromPreviousAERRates);
foreach (XmlNode node in xml.SelectNodes("/TextstringArray/values"))
{
var value = new List<string>();
foreach (XmlNode child in node.SelectNodes("value"))
{
value.Add(child.InnerText);
}
values.Add(value.ToArray());
}
}
From there, you can do as Jeroen mentions, loop through the list and output the first and second values.
Using Node API with Textstring Array

Hi Eddie,
No problem-o, usercontrols are fine.
Once you get back the value from
node.GetProperty("previousAERRates").Valueyou should have an XML string. You could then pass it to a function that will return you something more usable.e.g. code snippet taken from the Razor model-binder
From there, you can do as Jeroen mentions, loop through the list and output the first and second values.
Cheers, Lee.
