How can I set a default value for the combobox to display? My combobox is filled with data from a list and I need it to display one of the values from that list. I have a product and the its category is displayed in that combobox and I need that when I
see the product details the category combobox value be set to the specific product category. I have tried using something like combo1.SelectedItem = "aaaa" but it doesn't work.
Well, I will try to explain the details of what I want to do and how I need to set that value for the combobox.
I have a Silverlight page that shows a datagrid of products and when I select one of the product another page Silverlight is opened and I am supposed to see the selected product details. I am sending the product id as a parameter to the new page and I get
all the information needed but for the Category combobox I don't want to get only the whole list of existing categories but when the page is loaded with all the data I want to see the value I choose for the combobox and not as unselected.
I have not used any DisplayMemberPath. I don't think it applies in my case. Specific code that could help I don't have. I just retrive the data needed from a wcf service using the product id and display all in textboxes and comboboxes.

Have you set the DisplayMemberPath, if not then set it or else post your code.

You can first fill the combo and then set product i to it like this:
ddlProduct.SelectedIndex = productid;
or check this http://silverlight.net/forums/t/67956.aspx
