Working through the tutorial [URL]
I want to output the value of the 'caught' exception as all the database queries are wrapped in try catches.
How would I do this?
I have added a label to my form but not sure how to get a value in it! (Still thinking old ASP.NET)
I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour.
If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below.
E.g.
I have file called JScript.js containing the code:
function myAlert() {
alert("Hi World");
}
And in my Default.aspx file I reference the js with the code:
<script src="JScript.js" type="text/javascript"></script>
And in the body onload event I call the myAlert() function:
<body onload="myAlert()">
And finally in the Global.asax file:
Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs)
HttpContext.Current.Session("myVar") = "MyValue"
End Sub
If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads.
I have 2 lines in a text file like this
empid Name Salary Year
1234Johnny Wright 100002009
2344Travis Frank 302002009
For ex : my errors are in empid.. 2 empid's have alphabets which has error.
I m able to display only one error at a time. either 1st or 2nd.
How to display both errors at a time.?
What would be the best way to catch exceptions and display a detailed message in ASP.NET? I know in regular windows development, you can use an MessageBox.Show(ex.Message) to display the error details. How is this possible in ASP.NET? Is there an example out there someone could direct me to? I have not been able to find anything yet.
View 3 RepliesI am passing values from textboxes on the webform to my stored procedures where it should insert values passed.
It is giving an error like Cannot implicitly convert type 'string' to 'System.Data.SqlClient.SqlParameter' at place where I am cmdselect.Parameters.Add("@PackageName", SqlDbType.VarChar, 50) = PN; where PN is string type .
I have a C# web forms ASP.NET 4.0 web application that uses Routing for URLs for some reason custom errors defined in the system.web section of my web.config is entirely ignored and it will fall back the IIS errors.
This gets entirely ignored

This would be a minor inconvenience except that by the fact it falls back to IIS native instead of my application it completely circumvents Elmah logging my 404 exceptions correctly.

I would like to store some business flags (like: isFavorite, isOnLive etc.) per an html table row that won't be visible to user.
In practice, I have a simple ADO.Net DataTable on my code-behind which is used as a data-source for a asp.Net GridView control.
This table contains some business flags on its 0th, 1st, 2nd columns.
I need to store those columns on the rendered HTML of the grid-view -so that I can reach them via JavaScript- but I do not want them to be visible.
I hv a filed in db having 60 values. I want them to be displayed as checkbox values on my UI.but i want those checkboxes as 15 values in 1 column.15 in 2nd col.15 in 3rd col.and last 15 in 4th coln. how to do it?
View 3 RepliesSo to pretty much make this short and sweet, I have a page variable defined outside of all my methods and functions called buttonpressed. It is used to keep track of which button has been pressed on the app. For example, in the onclick event of my Edit button there is a line:
buttonpressed = "Edit"
I use this to decide what kind of query to perform to my database. My problem is whenever I hit my save button(which uses that buttonpressed value in an if statement to decide what query to perform), the variable value just magically disappears.
I tracked the value to make sure that it is being changed and store correctly based on my add, edit, and delete buttons. As soon as I hit my save button, the value of that variable goes blank.
I wanted to find out if there is a way of getting a parameter or variable value out of an XSL file. For example, if I have the following:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:variable name="username" select ="usertest"/>
<xsl:variable name="password" select ="pass"/>
<!-- ... -->
</xsl:stylesheet>
I would like to read the username and password values from the XSL and use them for authentication. I am using ASP.Net and C# to perform the actual transform on an XML file.
share code with me that would allow me to read the XSL variables from ASP.NET/C#.
I am using C#. I have got below format values in my SESSION variable ["FROMDATA"], I am using DICTIONARY to store the FORM Posted Data. see the related question.
Below are the some values in my SESSION Variable.
1) key - "skywardsNumber" value-"99999039t"
2) key - "password" value-"a2222222"
3) key - "ctl00$MainContent$ctl22$FlightSchedules1$ddlDepartureAirport-suggest" value-"London"
4) key - "ctl00$MainContent$ctl22$ctl07$txtPromoCode" value-"AEEGIT9"
.
.
....so on
Now I want to create a CLASS with METHOD in it, in which I will just pass the "KEY" and it will first check it for NULL OR EMPTY and then it will return its value from the SESSION Variable ["FROMDATA"].
consider this scenario: a user on my website has a profileID. There are some pluginID's associated with this profileID.
E.g.: User1 might have 2, 3 and 5 plugins associated with his profile.
When the user logs in, I store the profileID of the user in a session variable cod. ON a certain page, the user tries to edit the plugins associated with his profile. So, on that page, I have to retrieve those pluginID's from the DB.
I have applied this code but this fetches only the maximum pluginID from the DB and not all the pluginID's.
[Code]....
I was trying to figure out how can I store multiple pluginID's in this session variable?
I need to query for a session variable called 'steps' every 10 seconds from my Webform in ASP.Net using javascript. This session variable holds an integer value.

View 5 RepliesI have a simple user control which toggles between the visibility of a few images depending on the UserId. When the page is loaded for the first time, the userID is being assigned correctly (I'm debugging). However, there are two other buttons on the page for filtering the type of users, they are perform their functionality via Ajax (not the toolkit, but the normal javascript ajax) When one of these buttons are clicked, the user control cant get the userid, it always comes up as Zero. Oh, btw, the usercontrol is in a DataRepeater, so it occurs for each of the user.. all the time.. or thats the Idea. I have several other pages like this, (none of them have ajax) and the user control has no problems whatsoever.
My User control code:

And the Data Repeater is something like this:

Here, Immediately after the userControl <ucAB:....> line, I am printing the userid just to see if its valid (by <%# Eval("UserId") %> and the user id's are valid too. I dont understand why the User Control cant pick it up on ajax postback?

View 7 RepliesHow can I pass two variable values to a web service web method using JavaScript and a DynamicPopulateExtender?
Some background of my issue:
I have a fully working cascading drop down list accessing a database.
My parent Cascading Drop Down List is a list of countries and the child displays the relative regions i.e.: USA returns Iowa, Maryland, Oregon etc.
I also have a 3rd Drop Down List control that allows the user to select the language to display the region details i.e.: Selecting the language of Chinese will return a list of regions of the USA in Chinese (held in the database).
I now want to display the translated country name from the 3rd Drop Down List in a label on the page.
I cannot just use the text from the country drop down list as this text value remains in English. The translated value must be returned from the database.
So far, I have installed a DynamicPopulateExtender:
[Code]....
I then wrote a web method (in the Cascading Drop Down local Web Service) to return the translated country name. To do this I have had to hard code the countryID (10663) and the translationLanguageID (1331) asshown below:
[Code]....
This does return the translated country name, but the variables are hard coded!
My question is how do I pass the countryID and the translationLanguageID to the Web Method GetTranslatedCountryName() from the DynamicPopulateExtender? Or even if there is a better way to achieve my task?
Is it possible to assign all values in session to variable.
retrieving some values from first page with this code
Dim retProductIDs As List(Of Integer) = CType(Session("ProductIDs"), List(Of Integer))
I have a global error trap in the Application_Error method of Global.asax that writes any unhandled exception to a log file.
Is there anyway of reporting the variable names and their values as part of the exception report?
When I build my program, if there's one error that prevents it from running, instead of just getting the one error I'll get around 50 additional errors in addition to the real one such as:
Error 27 Validation (XHTML 1.0 Transitional): This name contains uppercase characters, which is not allowed.
Is there any way to not show these?
