I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.
I'm just beginning to learn MVC, so there's a good chance I'm complicating this more than necessary... I simply have a drop-down list on my view that is populated using a list of the model. That works fine. What I want to do is have a DetailsView below the dropdown and change the details displayed when the user changes the selecteditem in the dropdown. Simple, right? I can't quite figure out if I need to create a new action in the controller, and how do I bind the details view, or table, to the selected value? There's gotta be a simple demo of this somewhere, but I haven't been able to find it yet, so I thought I'd post here and see if someone could point me to a good sample?

i have a very strange issue with a user control we are dynamically loading on an asp.net web page(.net 2.0). the user control has 3 dropdowns, one of which has a selectedindexchanged event attached to it (which loads the third dropdown with a set of values).
the weird thing is, if there are currently any invalid fields (where field validators have been activated) in other parts of the form, when you go to select the drop down in question on the FIRST change it does nothing, but then when you change the index again it works perfectly! i dont understand how the event wont fire for the first change, but for every change thereafter.
However, if all these fields are filled in correctly above the usercontrol, it fires off the selectedindexchanged event correctly.
in regards to validation i have disabled ALL POSSIBLE validation in order to try and eliminate it as a culprit, so i dont understand how validation can be affecting the usercontrol.
