C# - Getting XslCompiledTransform, Load To Load A File In A SharePoint List?

Mar 3, 2010

I'm having difficulties getting XslCompiledTransform.Load method to take a server path. I googled around and found that I need to do something like:

xslt.Load(System.Web.HttpContext.Server.MapPath(xslPath), XsltSettings.Default, new XmlUrlResolver());

But it returned an error saying HttpContext is null.

I also tried:

xslt.Load(System.Web.HttpServerUtility.MapPath(xslPath), XsltSettings.Default, new XmlUrlResolver());

That also returned an error saying an object reference is required for the non-static field, method, or property 'System.Web.HttpServerUtility.MapPath(string)'

The xslPath has a path that points to a xsl file in Sharepoint Web. I just want XslCompiledTransform to load the xsl file with the server path. Is it possible? If so, what is the proper way or hackish way of doing it?

EDIT: I have access to a SPWeb object which contains the path to the xsl file. However when I check the ServerRelativeUrl, it just says "/MyTree/xsl.xsl". The problem here is I couldn't get the XslCompiledTransform.Load to load the file from SharePoint list.

C# - Cant Set Dropdown List Selected Value In Page Load

Jun 3, 2010

I'm trying to set the selected value of a ddl during page load ie. before databind.

This causes "selected value does not exist" errors. So I force a databind, and add a new element if it does not exist in the data source.

However it looks like when the databind is performed later in the page lifecycle that my added element(s) are removed/overwritten.

Am I setting the values in the wrong part of the life cycle?

MVC :: Load Partial View With List Of Objects?

Jul 8, 2010

I'm really new to MVC (just started a few weeks ago) and new to Ajax (never looked at it before today). I need some design / technical advice concerning Ajax, MVC, loading partial views, and posting / getting from a view. What I'd like to do it load a partial view that takes in a list of objects that have been queried from my db into an details-type view. The details view already has some other content that has been handeled and loaded from information pulled from my database and setup through some actions. It is strongly types to a model.

Below is the partial view I've created thus far:

[Code]....

And here's a portion of the Details page:

[Code]....

I'm not sure what to do for the Ajax.ActionLink. I'd like for a use to be able to type into the text box on it's left and hit "Add" (the Ajax link) and have the application add the content in the text box to the database. Should it be something else? An <input>? The Controller code piece is below:

[Code]....

So it should be adding the member into the repo / db and then reload the contents of the partialview. Instead, it's reloading the whole page and not just the partial view. (the url is changing from /project/details/5 to /project/membersection/).

Possible To Populate Text Box With A List Of Strings In Page Load?

Apr 4, 2013

I found that I don't need to use jQuery or AjaxToolKit to use a textbox with autocomplete instead using the AutoCompleteType() class.However, base in the documentation it says the autocomplete will just trigger after the button was click at first instance, with that
description looks like what I want to do will not be applicable.Is it possible to populate the textbox with a list of strings in page load? so that if I type in a textbox it will give me a complete list of strings already.

Web Forms :: Strange Dropdown List Behavior On Page Load?

Apr 3, 2010

I have a page with 14 dropdown lists. In the first page load (ie. not isPostback) I set the selectedIndex of the dropdownlists individually but I find that they are all set to the value I use for the last dropdownlist set. Here is the code

comboFirstJudge1.SelectedIndex = 0
comboFirstJudge2.SelectedIndex = 0
<so on for all the dropdown lists until the last one>
comboFirstJudge14.SelectedIndex = 4

The result is that all dropdown lists have SelectedIndex = 4. If I run the same code on a postback it works just fine (the first lists have SelectedIndex = 0 and the last one = 4).

SQLDataReader Find Value Of Each Row?

Nov 10, 2010

I used to use datasets instead of sqldatareaders and I used to be able to do something like this

If dataset.tables(0).Rows(0)(1).ToString()) = "N" Then
lbl.Text = dataset.tables(0).Rows(0)(2).ToString())
Else
'Do Nothing
End If

This obviously doesn't work with sqldatareaders.I have code to see if the SQLDatareader has any rows but was wondering if there was a way to get the value of each rowI'm guessing this is possible and i've had a look around but can't seem to find anything

Dim conn As SqlConnection = New SqlConnection("server='h'; user id='w'; password='w'; database='w'; pooling='false'")
conn.Open()
Dim query As New SqlCommand("DECLARE @investor varchar(10), @sql varchar(1000) Select @investor = 69836 select @sql = 'SELECT * FROM OPENQUERY(db,''SELECT * FROM table WHERE investor = ''''' + @investor + ''''''')' EXEC(@sql)", conn)
Dim oDR As SqlDataReader = query.ExecuteReader()
If oDR.HasRows or dataset.tables(0).Rows(0)(1).ToString()) = "N" Then
lbl.Text = dataset.tables(0).Rows(0)(2).ToString())
Else
'Do Nothing
End If

That is the code I have at the moment which obviously doesn't work

Web Forms :: Load Time Vs # Items Graph For Dropdown List Boxes?

Jan 20, 2011

I've noticed that page load time increases dramatically as you load up a ddlistbox with items. 10,000 or so results in a pretty much unacceptable wait time for my setup. The dropdown I'm trying to load is Airports - like all of them. What are some alternative UI solutions that give the user the ability to easily select any (literally) airport, but without a ginormous page loading time? (Currently the dd is keyed to the airport's 3 letter code, so it's convenient for the prepared user to just type the 3-letter code and have the right airport selected. The display is then set to code, city, country.)

Difference Between SqlDataReader.NextResult() And MARS

Sep 19, 2010

hile i have been working with application perfomance tuning part i found an article for doing the same from Microsoft. it suggests me to reduce the round trip between application and database by using Sqlbatch statements. i got two ways to achieve it 1. SqlDataReader.NextResult() - we can use single connection to execute sql batch statements2. MARS (Multiple Active Result Sets) - we can use single connection to open multiple readers and execute the batch statements
