Display array values in RadioButtonList
Hello Experts
I have a radiobuttonlist on my aspx form. In the code-behind I populate this list using a simple array:
accessarray = strUseraccesscorp.Split(",
rblStoreChoice.DataSource = accessarray
rblStoreChoice.DataBind()
This displays the string values properly. An example of the data being displayed:
1,2,3,4
Once split, of course, it looks like this on the radio button list:
1
2
3
4
Instead of showing the numeric values I'd like to display something more readable. Is there some way I can loop through these array values and add a DataTextField value to the RBL of something easier to read?
Example:
If value = 1 then A elseif value = 2 then B elseif value = 3 then C and so on...
How can I show a better radio button list yet still use the numeric values when a selection is made?

I'm not familiar with ArrayList. I just looked it over and I'm not sure how it will solve my problem. I won't always know the values I'm using to populate my current array. There are 15 different possible values. Sometimes the array will have 1 value, sometimes it could have 10. My interest is in hard-coding a real name for these values that I can use to display on my radio button list, while keeping the original values as the DataValueField so it can be used when a selection is made. I thought maybe a loop would work in this case but I'm unable to write one on my own.

Hi Randy
Thanks for your response. I think I need something along the lines of this:
accessarray = strUseraccesscorp.Split(",
rblStoreChoice.DataSource = accessarray
For Each RadioButton In rblStoreChoice.Items
If rblStoreChoice.DataValueFi
rblStoreChoice.DataTextFie
End If
Next
rblStoreChoice.DataBind()
I just can't make this work.

You need to populate hashtable with keys as data in your array and value with the text you want.

How do I add the existing array to the hashtable and then, based on the array value, assign text for it? Like I mentioned above, I won't always know the numeric values of this array, I need to write a statement that will convert all possible numeric values to text values so the list looks better.
Hello, jay-are,
I think that (in typical use) DataValueField and DataTextField would be the field names in the bound DataSource. In your case, the bound data has only one column and no field names, so these values will be empty strings. Also, these values are the same for all radio buttons in the set, so there is no point in including them in a loop through the radio buttons.
You can get the "numeric" value of the user's selection by using rblStoreChoice.SelectedVal
Maybe we need to get a better image of the "big picture" of what you are trying to accomplish.
Cheers,
Randy

Yeah I'm horrible at explaining what I actually need.
I want to present my users with a list of names. They can pick one name only and then perform an action. This action will need to know the value of what they selected. In my existing database I have these values stored in 2 different ways. Examples:
db values
1234
or
1234,4321,5678
There are 15 possibilities. These values in the db represent a word that I want to show on the list. So I need a way of getting the values in the db and presenting them as something that is easier to understand. I was hoping to just hard-code the actual text field on the list based on an if/then statement since I don't store them anywhere in the db. The action will need to know the actual numeric choice they made (example: 1234 or 5678).
I have the radio button list populated already with the actual data from the db, now I just need a way of changing what the list is displaying to something more user friendly. Hopefully this makes sense.
