Need to remove databinding of DropdownList when another dropdown list changes


I have many controls on my form, but in particular, I have 2 dropdownlists.  1 dropdown list has 2 values, and each value controls what the second dropdownlist displays.  This is an edititemtemplate and both dropdowns have the selecteditem set via '<%# Bind("fieldname") #>' on page load.  

THe problem is, if I change the value of the first dropdown, it errors out because the second dropdwon has a bound value that is no longer acceptable. 

Can I cancel the bind of the second control, if the the first one is changed?  I would like to cancel the bind, and update the values by using a different datasource depending on the value of the first dropdown or hardcode the new values.



If Dropdown1 has a value of "A" for example Dropdown 2 Shows Values "1", "2", "3"

If Dropdown 1 has a value of "B" , Dropdown2 Shows Values "4", "5", "6".

It binds fine initially, but if I change Dropdown1 from A to B, I want Dropdown2 to show the new values, maybe with a default of "Select an Item" and not error out b/c it's attempts to bind a value of 1, 2, or 3.


Hope this makes sence, b/c I'm

Remove items from a list literally not working as needed

This is why SharePoint drives me insane.  Everything I have been able to find on the web says I *can* programmatically remove list items from a list, all I have to do is a declining loop.  I have even copied verbatium several code examples found in this forum and on the web and every last one of them gives me a "Collection was modified; enumeration operation may not execute." error in the Event log.  This is a C# Windows Form Application we want to use to remove a common announcement from any announcement list in our entire site (top down).  We can *add* it to every announcement list without issue (seperate code).  Can anyone point out to us the error in our code below? using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Microsoft.SharePoint; using System.Text; using System.Reflection; using System.IO; using System.Diagnostics; using System.Xml; namespace RemoveAnnouncement { public partial class RAForm : Form { public RAForm() { InitializeComponent(); } private void removeAnnouncment_Click(object sender, EventArgs e) { const string a = "Application"; try { if (tlsURL.Text.ToString() == "http://" || tlsURL.Text.ToString() == &qu

When in the default list view, there are two Title fields. So what can I do in the list definition. Regards upzone

Remove Column from List Content Type


I have a list that inherits from 2 site content type.  When I added the "site content types" to my list it created a "copy" of it in my "List Content Type". 

Then I created a new column directly into my list, and at the bottom of the column creation screen there is a checkbox saying "Add to all content types" that was checked by mistake (I dont want the List Content types to have the column).

Now, is there a way I can remove those columns from the "List Content Type"? 

I saw that I can delete the "List content type" and re-link to the "Site content type", but I would need to delete all of my items before doing that, and I want to avoid that.
