C# - Validate (and Query) XmlElement Content Without OuterXML?
Feb 1, 2011
I have a Web Method (within a SOAP Web Service) with a signature of:
public msgResponse myWebMethod([XmlAnyElement] XmlElement msgRequest)
I chose to use the XmlElement parameter after reading that it would allow me to perform my own XSD validation on the parameter. The problem is that the parameter can be quite large (up to 80Mb of XML) so calling XmlElement.OuterXML() as suggested in the link isn't a very practical method.
Is there another way to validate the XmlElement object against an XSD?
More generally, is this an inappropriate approach for implementing a web service expecting large amounts of XML? I've come across some hints at using SoapExtensions for gaining access to the input stream directly but am not sure this is the correct approach for my situation.
Note: Unfortunately, I'm chained to an existing WSDL and XSD that I have no power to alter which is why I went with a non-WCF implementation in the first place.

I am trying to create a xmlElement from my asp page. The result xml node should look like the following:
<str:nam ft:qsType="qsString">NAME_I</str:nam>
I am having some problem putting the "str" prefix before the tag-name. I tried doing:
[Code]....
I get the result as:
<str:nam qsType="qsString" xmlns:str="xmlns:str="urn:instec-corp.com:qsdatamodel:autostructs:v1""> </str:nam>
I am not sure how to get the desired result which should be:
<str:nam ft:qsType="qsString">NAME_I</str:nam>

I have a two-character field for US State. I add a RegularExpressionValidator control to validate the input using
ValidationExpression="[a-zA-Z]{2}"which works to validate the content when something's entered, but it doesn't catch if someone just leaves the textbox blank.
Is there any way to validate within the same regex to catch an empty textbox?

I am trying to find out if there are records in a table
based on the results of the query.

The query works but the problem is validating the resutls
MembershipUser myUser = Membership.GetUser();
Guid userIdPosts = (Guid)myUser.ProviderUserKey;

var query = from t in context.TrackLists
where t.UserId == userIdPosts && t.ThreadID == currentThreadid
select new { t.UserId, t.ThreadID };

I have a button click event that adds a record to a table based on the userid and threadid the user is viewing. I am a bit new to entity so I am stumbling around. I have to where conditions
ThreadID == threadid
UserId == userIdPosts
I have this query but do not know how to execute it and if I have it as is I get this in the yellow screen of death Both the theadid and userIdPosts have data in them.
var query = context.TrackLists.First(t => t.ThreadID == threadid);
context.TrackLists.First(t => t.UserId == userIdPosts);
Sequence contains no elements
Line 90: // find is user has already tracked this thread.
Line 91: var query = context.TrackLists.First(t => t.ThreadID == threadid);
Line 92: context.TrackLists.First(t => t.UserId == userIdPosts);

I was using the code below to query the database and to show or hide content if the result was true of false. I use two panels so I can dispaly the right content block depending on EVAL
<asp:Panel
ID="Panel1"
runat="server"
Visible='<%#
(Convert.ToBoolean(Eval("GenreId"))).Equals(false) %>'>
<asp:Panel
ID="Panel2"
runat="server"
Visible='<%#
(Convert.ToBoolean(Eval("GenreId"))).Equals(true) %>'>
This was working with a CSS layout but I had to place all the content in a table and now it does not work. Is there another way to do it

I'm trying out the jQuery Validation plugin jQuery Docs Here is the markup of my form:
<% using (Html.BeginForm("action", "contoller", null, FormMethod.Post, new { id = "sxform" })){%>
<div id="manifest">
Manifest Option:<br />
<%= Html.DropDownList("docid", ViewData["manifests"] as SelectList, new { @class = "required" })%>
</div>
<div id="release">
Release Version:<br />
<%= Html.TextBox("release", null, new { @class = "required" })%>
</div>
<div id="locale">
Localization:<br />
<%= Html.DropDownList("localization", ViewData["localizations"] as SelectList, new { @class = "required" })%>
</div>
<div id="label">
Label:<br />
<%= Html.TextBox("label", null, new { @class = "required" })%>
</div>
<div id="session">
Session ID (optional):<br />
<%= Html.TextBox("sessionInput", null, new { @class = "required" })%>
</div>
<div id="submit"><input type="submit" value="Build" /></div>
<% } %>
JS:
$(document).ready(function(){
$("#sxform").validate();
});
I am using MS MVC HTML Helpers to render this form. The resulting markup looks fine. IE each input and selection element contains the attribute 'class' with the value 'required'. When I submit this form the validation does noting.

I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.

Error 17 'System.Web.UI.MasterPage' does not contain a definition for 'SetMetaTags' and no extension method 'SetMetaTags' accepting a first argument of type 'System.Web.UI.MasterPage' could be found (are you missing a using directive or an assembly reference?)

I'm in a little bit of a bind and have some weird behavior happening with a multiview control behaving differently between two machines, and of course, the production machine is the broken one. The page renders the correct content on both machines, but if I save the html file the production machine's source is wrong.
For example, if for step 1 the output should be just the letter A, and step 2 the output should be just the letter B, and step 3 the output should be the letter C, here is what happens:
Step 1:
Production - The source and output are both the letter A
Dev - the source and output are both the letter A
Step 2:
Production - the source is the letter A and the ouput on the browser is the letter B
Dev - the source and output on the browser are both the letter B
Step 3:
Production - the source is the letter A and the ouput on the browser is the letter C
Dev - the source and output on the browser are both the letter C
Is this some issue with SessionState? I'm very new to Multiviews and by no means an ASP expert.

I'm attempting to set a class on the body tag in my asp.net site which uses a master page and content web forms. I simply want to be able to do this by adding a bodycssclass property (see below) to the content web form page directive.
It works through the solution below but when i attempt to view Default.aspx the Content1 control loses its content.
Here is how I'm doing it. I have a master page with the following content:

We would like to use a contentPlaceHolder in our pages to set titles. What we would like to do is have the masterpage check the contentPlaceHolder to see if it has content in it. This way we can set up an e-mailer that will tell us what pages that don't have page titles since we have a fairly large site. We also have nested masterpages.

I'm very new to ASP.net. I have a c# content page, in which I want to inset this code half way down within the HTML:
<%
HttpResponse r = Response;
r.Write(HttpContext.Current.Request.ServerVariables["SERVER_NAME"]);

But when I view the page, this content comes out first, before even the tag.
how to get this code inline instead?

I want to bind data from SQL server to a dropdownlist. I have found out how to bind the content very simple: I have an array named mat, which I fill with data from this db-call: vb Code:
mat = GetData(clsDbInfo1.GetMaterialer(Session("language"), Session("sId")).Tables(0), Session("language"))
and then I bind the data to the droplist here:
vb Code:
For Each itemMat In mat lstMat.Items.Add(itemMat) Next
But here is my question: How do I bind value content to the dropdownlist just like:
vb Code:
Dim lst0 As New ListItem("Test0", 0) lstMat.Items.Add(lst0)Dim lst1 As New ListItem("Test1", 1) lstMat.Items.Add(lst1)
How do I do that? I have an array including the value content named matId, I want to add the content in the For-Each loop, is that possible??

My content page looks like this:
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Basket.aspx.cs" Inherits="Basket" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
</asp:Content>
Now, I would like to add some controls dynamically to the content when page loads, so I am trying the following code:
protected void Page_Load(object sender, EventArgs e)
{
Content2. // I want to add controls to it dynamically
}
The problem is that the Content2 control is not visible by the compiler and I am getting error about missing directive or assembly reference.

1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.
