Sitecore: Find Item from sitecore for the checked values in a checkBoxList

Question

I have a list of items as follows on my page. All the names shown below are items in Sitecore.

Now I want to check which items the user has selected and then get their ids(sitecore Item ID) on a button click. With the below mentioned code I can get the name but how I can get the Id (sitecore Item ID) of selected values?

// a temporary string to store the selected values
string values = "";

// A loop to check if each checkbox is selected then get the value
foreach (ListItem objItem in cblFoodItems.Items)
{
    if (objItem.Selected)
    {
        values += objItem.Value + ",";
    }
}

A bit more detail in case you like to know, how I am showing the items in the checkBoxList.

<asp:CheckBoxList runat="server" ID="cblFoodItems"  RepeatColumns="4"/>

Code Behind

Item foodFldr = Sitecore.Context.Database.GetItem("{42808F4D-5335-4BB6-911B-9B79E50CFE99}");

foreach (var foodItem in foodFldr.Children)
{
    var newListItem = new ListItem(foodItem.Name);
    cblFoodItems.Items.Add(newListItem);
} 

Answer 1

Change your code behind to:

foreach (var foodItem in foodFldr.Children)
{
     var newListItem = new ListItem(foodItem.Name, foodItem.ID.ToString());
     cblFoodItems.Items.Add(newListItem);
}

It will still display the Name of your item to the end users, but the value will be ID instead of item name.
