Web Forms :: Referencing A Webpage As A Variable?

Mar 17, 2010

Probably really easy but in my VB code I would like to say

If webpage = "ErrorPage" then
do seomthing
End if

So the thinking behind this is that if the ErrorPage is the open page on my site it feeds that into the webpage variable and then that runs the If statement.

Forms Data Controls :: Use A Query String Variable Created On The Fly To Populate A Child Webpage?

Feb 22, 2010

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;
}

I thought this would be easy but i cant find what i am looking for online

I have 2 pages, the first 1 has a button that opens another page. On this 2nd page the user selects a picture. When the user selects a picture the form closes. When they select a picture i want the image control on the first page to change.

I'm not sure how to do this, i guess i could set the image path as a session variable and reload the first page but again i'm faced with the problem of how to reference the first page from the 2nd

Web Forms :: Referencing Dynamically Generated Controls?

Jul 9, 2010

I'm displaying a table based on query results, and each record has a dynamically generated dropdownlist and submit button (and other controls, but this is simplified). That part works fine, but how do I reference the controls in a function? Here is the code I've tried. Create the controls:

[Code]....

Reference the control values (hopefully):

[Code]....

The function SubmitAction_Click fires when I click the Post button, so that part works. I just can't figure out how to reference the selected value of the dropdownlist. You can see that I'm explicitly giving the DDL a unique ID (DS_RecordID). I'm guessing I have to use FindControl to reference it, but I don't know how to format the code.

Web Forms :: URL Routing And Relative Referencing With Masterpage

Jan 3, 2011

I am using url routing to route user to his profile page. This profile page is a child page and is at the root directory. The css, javascripts are in css,js sub directories. Now the problem is of referencing in master page. All of the pages of the website runs smoothly except the page reached after url routing. This explains the problem i am having : [url]

I have used ResolveURL and URL.Content but this again shows up error saying me to missing an assembly directive. These are the other ways i tried in the master page:

<link rel="stylesheet" type="text/css" media="all" href="css/stylesheet.css" />
<link rel="stylesheet" type="text/css" media="all" href="/css/stylesheet.css" />
<link rel="stylesheet" type="text/css" media="all" href="../css/stylesheet.css" />
and
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="/js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="../js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="[Code]....
js/jquery-1.3.2.min.js"[Code]....
"></script>
<script type="text/javascript" src="[Code]....
js/jquery-1.3.2.min.js"[Code]....
"></script>

Or Is there anyway to redirect the user again as the usual site ran before url routing i.e.
on clicking the Home menu now the user is redirected to ...com/user/home.aspx whereas home.aspx is in the root domain. I am using this on the menu: <a id="A1" runat="server" href="~/Home.aspx">Home</a>

Web Forms :: Referencing Gridview In Multiple Methods?

When I try to run the page, I'm getting a 'does not exist in the current context' error.After a bit of poking on the internet, it seems that I might need to declare the gridview at the class level if it's going to exist in more than one method... problem is, I do that and it disappears from the page altogether.I'm obviously not doing this right - I'm declaring it like this (abridged version):

Forms Data Controls :: DataList Referencing Header From EditCommand?

May 12, 2010

I have a DataList with controls in the Header that are used to filter the DataList. Everything works correctly until I try and edit the filtered DataList. Having set the EditItemIndex, I then need to read the values from the header filter controls to ensure the Bind returns the same collection of rows. I am calling a function that should return the Header DataListItem so I can get the filter values if set. The problem is the DataList Item collection does not seem to have the HeaderItems in it.
