Using the OnTextChanged TextBox event isn't working

I have a repeater that places 600+ textboxes filled with data on my page. A typical user will edit several of these.

I would like the OnTextChanged event to run when I hit a save button, but it's not working.

All of my textboxes have the property OnTextChanged="TextBoxChanged" When my user selects the save button

<asp:Button ID="SaveChangesBtn" CssClass="SaveAndNextBtn" runat="server" 
            Text="Save Changes" onclick="SaveChangesBtnClick" />

I would like the TextBoxChanged event to run for each textbox that has been changed. How can I implement this?

Do you rebind the repeater on every postback or have you wrapped the databinding stuff (as you should) in a !IsPostback-check? 

if(!IsPostBack)
    DataBindRepeater();

If you databind web-databound controls on postbacks, all changes are lost and events won't be triggered.

I'm afraid OnTextChanged isn't quite what you are looking for then. OnTextChanged fires after a control has been entered, changed and then left (lost focus), so it fires when you select the next object.

you could use the OnTextChanged to accumulate a list of the IDs of the textboxes with changed contents, and then when you save, just loop over all the changed boxes to perform whatever task you like.
