    Data type with DDL

    Umbraco 6.** - sorry couldnt find a forum for this version.

    I have created a datatype called Colors and added Text and Value as below

    Red 1 Blue 2 Yellow 3 Green 4

    Under Document types i create a new property and set the Type to colors. Create a content page using the doc type above and i can see the colors i added.

    How could i use this data type with a user control dropdown list?

    Hi J,

    You can get drop down list value by using Prevalues like below.

        List<string> li = new List<string>();
    var values = PreValues.GetPreValues(DataTypeId);
    foreach (DictionaryEntry de in values)
    {
        PreValue pv = (PreValue)de.Value;

        // Here you will get id and value of the data type drop down list
        // pv.Id
        // pv.value
    }

    Hope this will help you.

    Regards,

    My code is 

            private void BindColors()
    {
        List<string> li = new List<string>();
        var values = PreValues.GetPreValues(1234);
        var ddlColors = (DropDownList)lv.FindControl("ddlColors");

        foreach (DictionaryEntry de in values)
        {
            PreValue pv = (PreValue)de.Value;

            // Here you will get id and value of the data type drop down list
            ddlColors.DataTextField = pv.Value;
            ddlColors.DataValueField = pv.Id.ToString();
        }

        ddlColors.DataSource = values;
        ddlColors.DataBind();
    }

    the error message i receive is "DataBinding: 'System.Collections.DictionaryEntry' does not contain a property with the name 'Blue'."? Any thoughts

    Hi J,

    Can you please check the ID of the data type that it is proper or not?

    And try with the below code.

    private void BindColors()
    {
        List<string> li = new List<string>();
        var values = PreValues.GetPreValues(1234);
        var ddlColors = (DropDownList)lv.FindControl("ddlColors");

        foreach (DictionaryEntry de in values)
        {
                PreValue value = (PreValue)de.Value;
                ListItem li = new ListItem();
                li.Text = value.Value;
                li.Value = value.Id.ToString();
                ddlColors.Items.Add(li);
        }

    }

    Hope this will help.
