I have Master Page and ascx user controls in my application.
how would I use the Cross-Page technique using the @ PreviousPageType directive.
useful links or samples to achieve this.
I am trying to use the Page class that exposes a property named PreviousPage from my User Control.
I have sqldatabase tables.I am reading table data and putting in a tabconatiner(wth tabs containing textbox, checkbox etc) specific to a client. If a client has more than one row i want to iterate through the rows and read each row data. Basically I want to use a button-click to read the next row data at put it in the tabs and so on. I used sqldatareader and a while loop.I can read the data but while loop iterates through the rows and show the last row data / i want to use a button to go to the next row and show data.
SqlDatareader reader=null;
reader=cmd.ExecuteReader();
while(reader.Read())
{
txtboxName.Text=reader["Name"].ToString();
}
protected button_Click(Object sender,EventsArgs e)
{
//I want to read row data in this button click
}
See what happens when you answer my questions! I come back! No good deed goes unpunished. I've built an Update form where my visitor can update data in dbase. I have a formview with several dropdown lists; none of which will update the table (all the textboxes, checkboxes and even Ajax enabled calendar work just fine). In the form below, visitor selects a CareerCluster from the ddl. Upon postback, the next ddl (pathwayListBox) populates with related data using the CareerCluster.selectedvalue in a query. At the same time, tsaOrgsDropDownList is also populated based upon the first ddl (CareerCluster).
When user selects from the tsaOrgsDropDownList the final ddl (tsaDropDownList) is populated. All this various selecting/populating works just fine on the form. The problem is: Nothing is updated to the table upon clicking the Update button. All other form fields do post as their supposed to except, I have other ddls on the page that are not related to the above series and they won't post either. My thought is that somehow, this is related to the postbacking going on. That posting back is overwriting the selectedValues with null or something.

Is there a way to force a non-secure form post to be secure? I understand there are ways to automatically resolve an http URL as an https URL but with form posts, is this type of redirection too late? Will the posted data have already gone through the wire as plain text?
View 3 RepliesI have a big form in which i have almost 10 update panels. some are having updatemode = conditional and others are always. Now by default when that page is opened i only show one dropdownlist.When that project dropdownlist (from which i populate the rest of the elements in my page) value is changed by user it takes long time to load the other elements. Also the other gridview which is also surrounded by update panel and mode in conditional takes long time to show edititemtemplate controls in edit mode.
I am unable to trace the reason behing delay. Few days ago it was working fine and fast but now it is slow.

I want to do is create a simple page which allows a user to post data into a data table. It should not allow them to view, update or delete any data.
Is there a good online tutorial which would guide me through how to do this in Visual web developer 2008?
I have connected a db, and can add "SELECT" controls to view forms, but I need to be able to INSERT to the table.
I need to delete all the item what I seleted or I Checked.so I collect all the ID I selected .
then what should I do next?I could not find a submit button to send them,they are not in a from.So I try to collect them to a JSON object and then use AJAX to send them to server.
I have a form that submits the game score. Is there any way to check whether that game score is not tampered during submission. I am using POST method, for GET method we can use HASH, but i am looking for POST method

View 1 RepliesI have a simple contact info webform with some validation rules developed in VS2010 that inserts a row in a SQL 2005 Express db.
However it does not always insert a row. (does for me !) There are no errors reported either in the browser or in the event log.
how I can narrow down the cause?
My code is faily simple. Basically the button calls the Insert command in the SqlDatasourcce , as generated through VS I do have one piece of code that forwards the user to a new page once the form is fillied in.

I hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.

I have SQL Server Database Primary Data File.
I want to recover the data from that file in to my data base which has the empty tables.
I have Microsoft SQL Server Query File which contain the table structure.
Here is what I need to do:
- SELECT from a table
- Do something to the data after the SELECT but before anything else
- let the controls that are bound to my data see it.
I've already got working code to Undo my something when Updating or Inserting
These are the requirements:
- use a plain-jane SqlDataSource to do the SELECT
- doing the something has to take place at the SqlDataSource, not in events of the databound controls.
From the MS site the SqlDataSource.Selected event is where I should do "post-processing" however I can't find any examples of doing so.

Im struggling with a way to bind multiple rows of sql data to specific controls, what im trying to acheive is having a list of questions / answers in my SQL db and loading them into my web form to build a questionaire.
The data i load into the form depends on criteria like which questionaire is it (there will be 2 seperate ones) and what language should it be loaded in, this will be controlled using drop down lists and passing these parameters to the SQL select statement.
The problem i have is i am unsure which method to pull the data out of the question column in my table, and bind it to seperate controls row by row, should i use a SQLDataReader or load the data into a dataset, or run a stored procedure to pull the data?
Which is the best way to get data from sql and bind it to controls in this situation?
For example:
label1.text = sqlcolumn1.row1.value;
label2.text = sqlcolum1.row2.value;
Etc...
asp.net with vb. I thought this would be easy but have been reading for an hour and not found out how to simply repost a page where form data has been entered and return the page with some error messages about what was entered. I want to return the page with all input controls with the data just as the user entered them before submitting. the error messages are labels that were blank when the page is first loaded. preferably the page returns focused to the topmost error error message. if that can't be done I would populate some label at the top of the page with something to the effect that 'errors were found, scroll down to see the errors'
