View 13 RepliesI'm trying to create a webpage that allows the user to click a button and it will open up a folder on their local hard drive. I've tried doing this in html and javascript, but from what I've read I don't think it is possible (reguardless I want to do it in asp.net so I can learn about it). However I was able to open up a folder when the page loads with asp.net using C#. My problem is that I cannot figure out how to get it to run when the user clicks a button or a link. How can I make the C# CodeBehind run when the user clicks a button?

I have developed an asp.net website in VS2010. The defaultDocument is set to default.aspx in the root directory, as I have dome many times before.For reasons unknown an asp:button in default.aspx is not firing correctly when the url is typed in without the file extension.
For example, if I type the url www.mywebsite.com the default.aspx page will load as expected, however, the button will not fire (it does postback but doesn't fire the server click event).If i type in the url www.mywebsite.com/default.aspx it works as expected.
The problem I'm having only occurs in a live environment (I cannot recreate the error on the localhost).

If webpage = "ErrorPage" then

I have developed the below web page which has an asp.net 3.5 listview control as it's frontend and an sql server db as it's backend.
[URL]
The first row on the web page is the inserting row. What I am hoping to achieve is that when the user enters their appropriate data they click the "Next" button to assign this dataset with it's own identity ID (customer_id) value within my database (this works perfectly), at the same time on the fly I want to use this customer_id as a query string variable to populate a child page (customerTrades.aspx) in order to pin further data to this identity. Currently I am attempting to use the below code within the iteminserted event of my listview control but I receive the error: "object reference not set to the instance of an object"??
protected void lvTrustAccounts_ItemInserted(object sender,
ListViewInsertedEventArgs e)
{
string customerID = e.Values["customer_id"].ToString();
Response.Redirect("http://www.tradeselector.co.uk/customerTrades.aspx?customer_id="
+ customerID + "");
}
Is this because the child page cannot find the customer_id variable being passed through the query string? Because it's not actually created yet? Am I using the wrong listview event? How can I achieve what I am looking for?
I must also mention that I'm using a linqdatasource to insert my data on runtime into my database. However, I am using the listview iteminserting event to insert my frontend dropdownlist selected values, code below:
protected void lvTrustAccounts_ItemInserting(object sender,
ListViewInsertEventArgs e)
{
e.Values["customer_created_date"]
= DateTime.Now;
e.Values["customer_update_date"]
= null;
DropDownList ddl_CountyInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountyInsertDDL");
DropDownList ddl_CityInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CityInsertDDL");
DropDownList ddl_CountryInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountryInsertDDL");
e.Values["customer_county_code"]
= ddl_CountyInsert.SelectedValue;
e.Values["customer_city_code"]
= ddl_CityInsert.SelectedValue;
e.Values["customer_country_code"]
= ddl_CountryInsert.SelectedValue;
}
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

I find a special circumstances as follows:
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.
