On my form I refresh a dataset in the Page_Load() event. But I also have a filter button which changes the dataset and reloads it. When the user clicks a button, the dataset gets refreshed twice. I would like to modify the Page_Load() event so that if the page is being reloaded because of a button click event, then I will skip refreshing the dataset in the Page_Load() event. Is it is possible to determine that the page is reloading due to a button click event?

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

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 am using a web form in vs2010 and in my form am having a gridview with button on footer. I have written the code to create a new row while click the button. If I click the button i got the following error
"unable to cast object of type 'system.web.ui.webcontrols.textbox' to type 'mysite.textbox"....
Below is the button click code.
private void AddNewRow() { int rowIndex = 0; if (ViewState["CurrentTable"] != null) { dtCurrentTable = (DataTable)ViewState["CurrentTable"]; DataRow drCurrentRow = null; if (dtCurrentTable.Rows.Count > 0)
The whole thing is in a form, and it doesnt postback when this button is clicked. Im no good with javascript, but i got a feeling thats not the problem.
