I have written a user control that captures some user input and has a Save button to save it to the DB. I use a repeater to render a number of these controls on the page - imagine a list of multiple choice questions with a Save button by each question.
I am loading the user control inside the repeater's ItemDataBound event like this (code simplified):
[code]....
The problem is that when the Save button is clicked, the page posts back, but lbnUpdate_Click is not called. The Page_Load event of the page itself is called however.
I should mention that the repeater is part of a user control, and that user control is loaded inside another user control (this is a DotNetNuke site which makes heavy use of user controls). The Save button link looks like this:
javascript:__doPostBack('dnn$ctr498$AssignmentsList$rptAssignments$ctl04$ctl00$lbnUpdate','')

I have a user control that displays some database records when I first hit the page. When I click the submit button the page load event fires again, loading the user control again. Then the button click event fires inserting a new row in the database which is not shown on the page because the user control already did its stuff. If I could get the user control to do its stuff after the button click event I could then see the newly inserted row. I can do this by pulling the code out of the button click event and sticking it in the page load event. However, I think that would be bad code flow. How can I get the user control to do its stuff after the button click event has fired?

I want to put five buttons: introduction, product, history, feedback, contact. And when I click any one button, that button became dark blue, and others remain, no changes. So I write the following code:
Protected Sub ImageButton1_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton1.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION BLUE.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton2_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton2.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS BLUE.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton3_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton3.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY BLUE.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton4_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton4.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK BLUE.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT.jpg"
End Sub
Protected Sub ImageButton5_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton5.Click
ImageButton1.ImageUrl = "~/image/CHOICE INTRODUCTION.jpg"
ImageButton2.ImageUrl = "~/image/CHOICE PRODUCTS.jpg"
ImageButton3.ImageUrl = "~/image/CHOICE HISTORY.jpg"
ImageButton4.ImageUrl = "~/image/CHOICE FEEDBACK.jpg"
ImageButton5.ImageUrl = "~/image/CHOICE CONTACT BLUE.jpg"
End Sub
It is workable, however there is only one problem: when i debug it some times it is ok, but some few times the button suddenly became small.

I have little strange question. I would like to Validate my Page Controls on the button click which is there in the User Control. This user control is placed on the Page. If I check Page.IsValid property on button click event, it returns false. But Validation Summary message doesn't popup. So user doesn't know what's happening. It will not save the information and it won't give the validation message too.

I have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.
I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.

On my Search page, I have a search textbox, four drop-down lists and a "Search" button. If I use only the drop-down lists and click the "Search" button, results are immediately returned. However, if I enter text into the textbox and click the "Search" button, nothing happens until I click the "Search" button a SECOND time.The processes that occur for the latter scenario are as follows:Text entered into textbox, and Search button clicked:On FIRST click attempt:
1. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Search.aspx is called
2. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Main.Master.vb is called
3. Process stops! No results
On SECOND click attempt:
1. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Search.aspx is called
2. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Main.Master.vb is called
3. Protected Sub SearchSubmit(ByVal sender As Object, ByVal e As EventArgs) Handles btSearch.Click for Search.aspx is called
4. Search continues and completes.
So, why will the 3rd step not kick in until clicking Search for a second time
[Code]....
If I reach this last Sub, everything else beyond this works fine.

I am a ASP.Net Web Forms developer and new in MVC. I observed that MVC reccommend not to have code behind file. In Web Forms, we handle events in code behind then change properties of various controls there. How to do the same in MVC? For example, if I have to change back color of a label on click of a button then how to do this in MVC?
