View 4 RepliesDo I have to use XPath to link my XML document to a repeater or is there another way. here is my some of my code.
first page loop through data and store as XML:
public virtual void Button_Click(object sender, EventArgs args)
{
TableControl recControls = (TableControl)this.Page.FindControlRecursively("TableControl");
if (recControls != null)
{
TableControlRow[] rows = recControls.GetSelectedRecordControls();
this.Page.Session["RegistrationTableControl"] = rows;
// create XML writer to

[Code]....
I have take the XML data and place them in page 2 become the data source of the repeater.
I have a XMLDataSource somewhat like:
<bookstore>
<author>author1</author>
<publication>publication1</publication>
<book>
<genre>Thriller</genre>
<name>ABC</name>
</book>
<book>
<genre>Romance</genre>
<name>XYZ</name>
</book>
<book>
<genre>Horror</genre>
<name>000</name>
</book>
</bookstore>
I am storing these in a asp:formview. I am able to store author and publication values but not sure how can I store the value of book/name based on some condition? Actually I just want to use condition that I need to store the value of "name" if "genere=Romance". something like this. I tried using XPath expression bookstore/book/genre[. ='Romance'] but not sure how to access the value of tag. Checked the following resource:

here my code that gives error-
OnClientClick='javascript:DragRevId(<%# XPath("ReservationId") %>);return false;'
I'm creating page to put together a list of cinema trailers on an asp.net web page inside of a repeater.
The source of the data is an online XML feed.
To do this I'm binding the repeater as follows...
string XML_FEED_URL = "http://some-cinema-feed.com/comingsoon/";
XmlDataSource data_source = new XmlDataSource();
data_source.DataFile = XML_FEED_URL;
data_source.XPath = "/movies/movie[position() > 0 and position() < 3]";
this.moviePreciewsRepeater.DataSource = data_source;
this.moviePreciewsRepeater.DataBind();
The issue is that the length of the feed changes regularly and rather than selecting a range of movies with the XPATH (i.e. 1-3 in the XML) I need to select 3 totally random movies from the XML and bind this back to the repeater.
I am trying to bind xml to GridView.
I am not able to use Xpath in HeaderTemplate like <HeaderTemplate>'<%#XPath("Name")%>'</HeaderTemplate>
Error: Value cannot be Null.
Well, how to I insert my Xpath value into HeaderTemplate from Serverside?

We are using Selenium and are looking for a similar way to select elements, ignoring the prefixes that ASP.NET generates.

View 1 RepliesI have a listbox element in aspx page which id is attributesList.
I want to select this element to track its change event, but i cant directly select its id because asp.net changes its id on runtime.
its id, attributesList changes into ctl00_adminPlaceHolder_attributesList.
so what i want to do is to use a "contains" xpath expression to select the element.

I have four fields on my insert form: Server, Farm, Silo and Reason. Farm and Silo populate based on the name of the server that is entered. If I take out the SelectedValue='<%# Bind("value") %> the form doesn't error out, but the fields don't post back to the DB.

I think I am struggling with something that may not be entirely relevant to XPath, but this is the function I am trying to use. I have a code snippet here that works,

It prints out: Items for page 1 is: 1 to 10. What have I missed here regarding this issue?
I am getting the following error
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
but all I am trying to do is inside a ASP.NET REPEATER Control

<% { %>
<asp:ImageButton runat="server" etc.... />
<% } %>
i have a FormView, it renders fields from a SQLServer database but also much static text specific to the database value I get. I dont know if this can be done in the code behind and put all this in a function . I put it in my formview
<ItemTemplate>
<% If Eval("Feature1") = "Yes" Then %>
<%# Eval("Username") %> A lot of text
<% elseIf Eval("Feature1") = "No" Then %>
<%# Eval("Username") %>
A lot of different text
<% End If %>
</ItemTemplate>
If I do the code above I get error message:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. Can this be done within the formview?
[code]....
gives me error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I could write : <%# Eval("SaveDate") != DBNull.Value ? do magic But I need to do lots of html magic in if statement.
I know I should add # in order to use Eval, but not sure about correct syntax.
I have a big problem...I have made a page has a Data FormView controland the insert template of this Formview control has DropDownList to allow the user to choose section (SectionsDDList)..and there's also another DropDownList allow the user to choose a teacher (TeachersDDList)...more infothe SectionsDDList get the section list from SqlDataSource control which the "Select Command" of is:"SELECT section_id,section_id FROM sections"the TeachersDDList get the teachers list from another SqlDataSource control which the "Select Command" of is:"SELECT teacher_id,teacher_name FROM teachers WHERE (section_id = @section_id)"finallyI want the TeachersDDList to be filled with teachers according to the selected section from the SectionsDDList...So,I enable the Auto postBack function of the SectionsDDListand add the next code for the SectionsDDList_SelectedIndexChanged event:TeachersDataSource.SelectParameters["section_id"].DefaultValue = ((DropDownList)sender).SelectedValue;be aware that both of the SectionsDDList & TeachersDDList have been Bounding to a column...and the problem I have faced is that:Exception Details: System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.maybe you want to know the Stack Trace:[InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.]
