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

If I reach this last Sub, everything else beyond this works fine.
i want to add a confirmation msg when click a button to delete my record, i cannot add the on client click msg on design page, due to i need do the checking for the checkbox before pop up the confirmation onclientclick msg.
My web form contains a postback button. The button will postback and call a server-side method. The method will process something that may spend about 20 seconds. However, user may try to click the button several times within the waiting period. The sequential clicking may cause the first running method incomplete and stop, since the second click postback will dominate the method and start again. How can I solve it?
PS: It can not use client side script to disable the button, because it requires to use some server-side validation within the method.
I put a server side button on the header page. The website is running fine. I use the same source and put it on IIS, it's also working fine but the problem is, i couldn't compile it anymore using my VS studio. It's showing no error so when I go and check the output (after scrolling down a bit and found one line says error). it says
C:InetpubwwwrootAmFraserIntranetheader.master.vb(31,0): error BC30506: Handles clause requires a WithEvents variable defined in the containing type or one of its base types.
C:InetpubwwwrootAmFraserIntranetheader.master.vb(32,0): error BC30451: Name 'keyword' is not declared.
keyword is the textbox on the header page. I also played around with AutoEventWireUp (true/false) and defining onclick event on the server tag but it is still not solving the problem.
have been trying to get to grips with the entity framework using the music store tutorial as a base reworking it to fit an existing application i havei have a database table called AuthorDetail. I also have AuthorDetail.cs Model, and a View AuthorDetail.cshtml strongly-typed to the Model. It's also declared as DBSet in the Entities class :DbContext under the application Models namespace.
