Hi and thanks for taking a moment. I need to know how to restrict the availability of  a dropdown value from a dropdown list control. I want to do something like what is below, however in c# this is invalid.  All of the original values for the dropdown list control are populated from a database. I need to filter them at the code level now. Any help greatly appreciated.

if (lblDept.Text == "Quality Assurance" || lblDept.Text == "Information Technology")
        {
 
            ddlComplaintstatus.Items[0].Visible = false;
          }

Have you considered just removing the item from the list if they are not allowed access?

Hi and thanks for your reply. Certain people may need to access those values however. I know how to write the conditional ( the "if" statement). Just can't figure out how to isolate the particular value and make it invisible.

If you will not know where the item is located in the list you may be able to do something like the following:
ListItem li = ddlComplaintstatus.Items.FindByValue("Pending");
if (lblDept.Text == "Quality Assurance" || lblDept.Text == "Information Technology")
  ddlComplaintstatus.Items.Remove(li);

You can add items manually with for loop to dropdown from dataset or datareader instead of directly binding them using 'DataSource'.

Method 1:
DropDownList.Items.Add("value")

Method2 :
To add items to the DropDownList, along with a Value Field, you can do something like this (the second item is the one that populates the Value:
ddl2.Items.Add(New ListItem("Item 1", "1"))

OR

You can remove the items after binding with DataSource like this:

Method 1:
ddl.Items.RemoveAt(index)

Method2:
ListItem li = dropdownlist.Items.FindByValue(strValue);
if(li != null)
    dropdownlist.Items.Remove(li);
