C# - Select Elements Added To The DOM By A Script
Aug 25, 2010
I've been trying to get either an <object> or an <embed> tag using:
HtmlNode videoObjectNode = doc.DocumentNode.SelectSingleNode("//object");
HtmlNode videoEmbedNode = doc.DocumentNode.SelectSingleNode("//embed");
This doesn't seem to work. how to get these tags and their InnerHtml? A YouTube embedded video looks like this:
<embed height="385" width="640" type="application/x-shockwave-flash"
src=[URL] flashvars="..."
allowscriptaccess="always" allowfullscreen="true" bgcolor="#000000">
I got a feeling the JavaScript might stop the swf player from working, hope not...

I've got a custom ASP.Net web user control I've built; done this enough times before but this one is misbehaving and I can't spot why.
Where the calling page includes the user control directly in its markup, all is well and the control behaves as expected.
However if the page adds this particular control dynamically (to a placeholder in the master page, which is what's calling this whole thing) the elements within it stay firmly NULL - nothing from the user control gets written to the client at all, including static content within the user control.

I am working on some ASP.NET web forms which involves some dynamic generation, and I need to add some onClick helpers on the client side. I have a basic outline of something working, except for one huge problem.
There are multiple HTML tables, each generated by a different ASP.NET web control. Each table can contain overlapping field names, which is causing a problem with my JQuery click event handlers. The click event handler is linking to unintended form fields in addition to the intended form field.
I have provided a simplified sample version of the code below. This code is trying to set the value of textbox box1 when a particular radiobutton is selected in the table with id=thing1. Obviously, the jquery code will be triggered for the form fields in both tables.
The tables are dynamically added to the webpage based upon different conditions. It is possible that no tables will be loaded, only 1 table, or both tables might load. In the future, other tables could be added. Each table comes from a different .net web control.
Other than renaming the form fields to make sure they are unique across all user controls, is there a way to have JQuery act only on the intended form fields? In other words, could the table ID be incorporated into the JQuery code in a manner that does not become a nightmare to maintain later?

I am having 3 ListBoxs(LB1,LB2,LB3).In LB1 I am binding the names of Courses through database.The code is shon below...
da1 = new SqlDataAdapter("SELECT COURSE_ID,COURSE_NAME FROM Course_Mst", con);
DataTable dt1 = new DataTable();
da1.Fill(dt1);
lstCourse.DataSource = dt1;
lstCourse.DataValueField = "COURSE_ID";
lstCourse.DataTextField = "COURSE_NAME";
lstCourse.DataBind();
Whenever I select particular course in LB1 all the content related to that course will be binded in LB2.The code is shown below.....
protected void LB1_SelectedIndexChanged(object sender, EventArgs e)
{
da2 = new SqlDataAdapter("SELECT SPEC_ID,SPEC_NAME FROM SPEC_TRANS WHERE COURSE_ID="+Convert.ToInt32(lstCourse.SelectedValue)+"", con);
DataTable dt = new DataTable();
da2.Fill(dt);
lstSpecilization.DataSource = dt;
lstSpecilization.DataValueField = "SPEC_ID";
lstSpecilization.DataTextField = "SPEC_NAME";
lstSpecilization.DataBind();
lstSpecilization.Focus();
}
I am having a ADD button.In LB2 I can select multiple items.When I select multiple items in LB2 and click on ADD all the selected items will be binded into LB3.The code is shown below...
protected void btnAddCourseDetaisl_Click(object sender, EventArgs e)
{
for (int intLoopIndex = 0; intLoopIndex <lstSpecilization.Items.Count ; intLoopIndex++)
{
if (lstSpecilization.Items[intLoopIndex].Selected)
{
ListItem li = new ListItem(lstSpecilization.Items[intLoopIndex].Text, lstSpecilization.Items[intLoopIndex].Value);
LB3.Items.Add(li);
}
}
}
My problem is when I select a item from LB2 and click on ADD the selecteditem is added to LB3 but if I select the same item and click on ADD the items are again added to the LB3.I want to prevent this.Pls respond me ASAP.

I have the following list of projects WebUI (WebSite) , DataAccess (ClassLibrary) , LogicLayer(ClassLibrary). Those of the project are purposively crated separately.But my scenario is, need to create only one solution file, then add all of the above projects under this solution file. So that i can be easiy interacted and changes can be made by opening solution file only instead of opening each project individually.
Simply all of the layer projects are under one roof means one solution. I tried it by adding solution first, then i added already existed project into this. But once after added already existing project the solution icon vanished by showing the icon of recently added project. By this way I could not add another project into this section too.Hope this is the way the basic real-time projects are created; to achieve the centralized control over architecture based projects.

The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
give me an example of how to do this?

protected void Button19_Click(object sender, EventArgs e)
{
SqlDataSource conn = new SqlDataSource();
conn.ConnectionString = ConfigurationManager.ConnectionStrings["Database2ConnectionString1"].ToString();
conn.SelectCommandType = SqlDataSourceCommandType.Text;
conn.SelectCommand = "SELECT FROM table1 (a, b)VALUES(@a,@b)";
conn.SelectParameters.Add("a",TextBox1.Text);
conn.SelectParameters.Add("b", TextBox2.Text);
int rowsAffected = 0;
try
{
rowsAffected = conn.Selectt();
}
catch (Exception)
{
Label1.Text = "Error";
}
finally {
conn = null;
}
if (rowsAffected != 0)
{
Label1.Text = "Data saved";
}

Can any one let me know about the below issue. I have a page which has three labels, say startdate,enddate and username. My issue is if the user doesnot select any of the above three then a message gets displayed as "Please select one search criteria" or if the user doesnot enter the date in correct format then i dispaly "Please enter date in mm/dd/yy" format. But what is happening is first time if the user doesnot select any then "Please select one search criteria" is getting displayed and after this message gets displayed if the user enters wrong format of date then both the messages are displayed.

I will declarate a attribute, but it gives me an error
This query works fine and returns 1 record from type int:
SELECT TOP 1 DataObjectVersionID
FROM tblDataObjectVersionPropertyValueText
WHERE PropValue like CAST('00010281' AS ntext)
ORDER BY DataObjectVersionID DESC
And when I will declarate a attribute/parameter it gives me an error:
DECLARE @dataObjectVersionId INT
SET @dataObjectVersionId = SELECT TOP 1 DataObjectVersionID
FROM tblDataObjectVersionPropertyValueText
WHERE PropValue like CAST('00010281' AS ntext)
ORDER BY DataObjectVersionID DESC
Error message:
Msg 156, Level 15, State 1, Line 2

I am trying to write a stored procedure that takes out a list of blog entries from a table (tblFeedEntry) as well as the amount of comments that each blog entry has gotten (tblFeedComments) but all I can get is the total amount of comments of all blog entries together, displayed on all entries. This is how my code looks today:
[Code]....
I am guessing that the problem is that the declared variable is not picking up the id of the blog entries, instead it picks up everything. The original select and the select in the declared variable are not connected. How do I connect them?

I was trying to set the alignment of elements within my web page that has some ASP.NET controls. Inside, the div tag, I need to set the alignment of Label control so that it is always right aligned in div. How can I set this?
Edit: Here's the HTML code:
<div id="UserLoggedinMessage" style="float:right; width:280px">
<div style="float:right;width:350px">
<asp:Label ID="Label3" runat="server"></asp:Label>
<asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">Login now</asp:LinkButton>
<!-- Serch Box -->
<div id="WLSearchBoxDiv" style="float:right">
</div>
<!-- Seach Box -->
</div>
</div>
So, this gives me my search box and Login Button in the same line. But the Login button is left aligned. I have correct this.

eb user control that basically lets the user choose whether she is a registered member or unregistered member, and to fill fields accordingly, i.e., if the user is member she is asked to provide her username and password and the sign up field are being disabled. if the user is not registred then she is asked to provide registration information and the login fields are being disabled. A very common practice, I assume.
each option has its own 'ValidationGroup' on the fields. i.e. the login fields have ValidationGroup="Login", the registration fields have ValidationGroup="SignUp"

So I am new to ASP.NET MVC and I would like to create a view with a text box for each item in a collection. How do I do this, and how do I capture the information when it POSTs back? I have used forms and form elements to build static forms for a model, but never dynamically generated form elements based on a variable size collection.
I want to do something like this in mvc 3:

Eventually, our team would like to move away from tables, but it seems like div tags are so much harder to use. In the above image, the layout was created using a table, but I cant figure out how to get a basic column structure working using div tags. How can I get those buttons on the same line?

Currently, I have a list of PhoneNumber objects that I display. Here's an example of the output of the view:
[Code]....
Notice the naming of these elements: name="existing_phone[labels][6]", name="existing_phone[numbers][6], name="new_phone[labels][]", name="new_phone[numbers][].Back in the Classic ASP days, I recall being able to do something along the lines of:
[Code]....
And that would give me a 2d array of phone numbers to work with. This doesn't seem to work in .NET. Has anyone tried to do something similar that can point me in the right direction?For new phones, I should simply be able to iterate through each item and insert into the database. For existing phones, I should be able to update (or delete if the label or number are blank) records based off of the id number supplied in the array.OR..if anyone has a better, alternate solution, I'm open to something else.
