When I am trying to create a calendar control in asp.net it throws me an error called
The 'namespace' attribute cannot contain spaces
The code written is:
<asp:TextBox ID="date1" runat="server" ></asp:TextBox>
<asp:ImageButton runat="server" ID="img1" ImageUrl="~/images/calendar.png" Height="25px" Width="25px" />
<cci:CalendarExtender runat="server" ID="cal1" PopupbuttonID="img1" TargetControlID="date1" Format="dd/mm/yyyy"></cci:CalendarExtender>
<cci:TextBoxWaterMarkExtender runat="server" TargetControlID="date1" WaterMarkText="Please Select Date To Proceed"></cci:TextBoxWaterMarkExtender>
Hoe to resolve this?

I'm trying to allow content editors to be able to choose the main banner image on a page by having it chosen through a Media Picker property.
I've tried the standard inline XSLT of:
<umbraco:Item runat="server" field="banner" xslt="concat('<img src="', umbraco.library:GetMedia({0},0)/umbracoFile, '" />')" xsltDisableEscaping="true" />
But in my simple template of:
<asp:Content ContentPlaceHolderID="ContentPlaceHolderDefault" runat="server">
<header class="home-header">
<div class="logo-wrapper">
<umbraco:Item runat="server" field="banner" xslt="concat('<img src="', umbraco.library:GetMedia({0},0)/umbracoFile, '" />')" xsltDisableEscaping="true" />
</div>
</header>
</asp:Content>
The rendered HTML comes out at:
<header class="home-header">
<div class="logo-wrapper">
</div>
</header>
I've read about using a macro to render images but my Umbraco knowledge is limited. If someone could provide steps for actually adding an XSLT macro, I'd be happy to try that out.
Unfortunately we are stuck on Umbraco v4.9 for now too so no <umbraco:Image /> tag for me.
I suggest you use a c# Umbraco macro instead of xslt. Umbraco 4.9 can do that.
An macro can in a differt file or simple use a inline macro:
<umbraco:Macro runat="server" language="cshtml">
#if (#Model.visual != "")
{
<img src="#Model.Media("banner", "umbracoFile")" class="foto" />
}
</umbraco:Macro>
Same as <img src="#node.Media("banner", "umbracoFile")" />
If anyone else finds this and you are not using MVC you can use this approach inside your template to get the image path you selected from the media picker
<umbraco:Item field='headerImage' runat='server'xslt='umbraco.library:GetMedia({0},true())/umbracoFile'xsltDisableEscaping='true'></umbraco:Item>
Where headerImage is the alias for your attribute name in your document type. This will render something like "/media/1002/sample.jpg" for instance
<asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True" CommandName="Insert"
Text="Registration"</asp:LinkButton>
<asp:LinkButton ID="InsertCancelButton" runat="server" CausesValidation="False" CommandName="Cancel"
Text="Cancel"></asp:LinkButton>
What is the problem in this? I am getting following error:
"Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: The server tag is not well formed."
To my knowledge, this is a good code.
You're missing a closing tag(>) after the Text="Registration"in the first LinkButton tag
<asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True" CommandName="Insert" Text="Registration"></asp:LinkButton>
<asp:LinkButton ID="InsertCancelButton" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel"></asp:LinkButton>
I need to read some value from DB in ASP, I try this code and works fine:
<asp:SqlDataSource ID="SqlDataSource12" runat="server" DataSourceMode="DataSet" ConnectionString="<%$ ConnectionStrings:conexion1 %>"
SelectCommand="select Quantity from XW_ReqLine where ReqNbr=#reqnbr1">
<SelectParameters>
<asp:QueryStringParameter
ConvertEmptyStringToNull="True"
DefaultValue="10124"
Direction="Input"
Name="reqnbr1"
QueryStringField="string"
Type="String" />
</SelectParameters>
</asp:SqlDataSource>
<asp:GridView ID="GridView15" runat="server" AllowPaging="True" AllowSorting="True" DataSourceID="SqlDataSource12" AutoGenerateColumns="true"></asp:GridView>
I need to change DefaultValue="10124" to DefaultValue="<%# DataBinder.Eval(Container.DataItem, "ReqNbr") %>" but after that, IIS show an error. The change is because this parameter is not constant
Note: I can't access the code behind (is a comercial software) and only I can made this modifications in the ASP file.
I have a repeater that is databound to a SqlDataSource
<asp:Repeater runat="server" ID="Repeater" DataSourceID="SqlDataSource">
<ItemTemplate>
<asp:HiddenField runat="server" Value='<%# Eval("Code") %>' ID="Code" />
<asp:TextBox ID="NumberNeeded" runat="server" Text='<%# Eval("Needed") %>' /><br />
</ItemTemplate>
</asp:Repeater>
<asp:Button runat="server" ID="submit" Text="submit" OnClick="submit_Click" />
<asp:SqlDataSource ID="SqlDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="rtvFiltered" SelectCommandType="StoredProcedure">
<SelectParameters>
</SelectParameters>
</asp:SqlDataSource>
I want to iterate over the repeater and get the value in NumberNeeded in submit_Click
protected void submit_Click(object sender, EventArgs e)
{
this.Repeater.DataBind(); //comment this guy and this.Repeater.Items has no items
foreach (RepeaterItem item in this.Repeater.Items)
{
String code = ((HiddenField)item.FindControl("JournalCode")).Value;
// below fails because "NumberNeeded" control doesn't have the Text input by the user.
int numNeeded = Int32.Parse(((TextBox)item.FindControl("NumberNeeded")).Text);
// Doing other stuff with numNeeded
}
}
The repeater displays its items perfectly on the page, but when I click the submit button, this.Repeater.Items is empty (unless I call this.Repeater.DataBind() in that method).
I've tried explicitly data binding Repeater in Page_Load and Page_Init within and outside of a !Page.IsPostBack check, and everytime I either get no Items, or no Text value.
I have gotten an almost identical setup to work in the past, on a page without a master page. I've also noticed that this.Master.EnableViewState is false in the submit_Click method, no matter if I set it to true in Page_Init or Page_Load. this.EnableViewState is true.
As you state, you shouldn't need to call DataBind() in your code behind, so the problem may be with the data retrieval. Does your stored procedure take any parameters? Have you tried adding CancelSelectOnNullParameter="false" to your SqlDataSource?
It was the EnableViewState setting on the master page.
In the Page_Load method of the master page this.EnableViewState was getting set to false. I changed it to Page.EnableViewState and everything worked.
this.EnableViewState = Page.EnableViewState; // add to Master page Page_Load method
do'h
I'm porting the servlet/jsp Netbeans' Affableben tutorial to JSF Framework, and want to use Facelets for the view.
I already have the JPA entities, the session beans and the managed beans. I'm starting with the View. However, I have not found the equivalent in Facelets to work around this line:
<a href="<c:url value='category?${category.id}'/>">
This is the full loop, both in jsp and facelets:
JSP code:
<c:forEach var="category" items="${categories}">
<div class="categoryBox">
<a href="<c:url value='category?${category.id}'/>">
<span class="categoryLabel"></span>
<span class="categoryLabelText"><fmt:message key='${category.name}'/></span>
<img src="${initParam.categoryImagePath}${category.name}.jpg"
alt="<fmt:message key='${category.name}'/>" class="categoryImage">
</a>
</div>
</c:forEach>
Equivalent Facelets code:
<ui:repeat var="category" value="${categoryController.items}">
<div class="categoryBox">
<h:link outcome="${category.id}"/>
<span class="categoryLabel"></span>
<span class="categoryLabelText">${category.name}</span>
<img src="./resources/img/categories/${category.name}.jpg"
alt="${category.name}" class="categoryImage"/>
</div>
</ui:repeat>
This line is not working in Facelets as expected:
<h:link outcome="${category.id}"/>
What would be a working equivalent in Facelets?

The <h:link> utilizes JSF implicit navigation and requires a real (implicit) navigation outcome value. You need to specify the view ID in the outcome. You need to specify request parameters by <f:param>. You also need to nest the spans and the image in the link as you did in your initial example. Assuming that you have a category.xhtml file in the root, this should do:
<h:link outcome="category">
<f:param name="id" value="#{category.id}" />
<span class="categoryLabel"></span>
<span class="categoryLabelText">#{category.name}</span>
<img src="./resources/img/categories/#{category.name}.jpg"
alt="#{category.name}" class="categoryImage"/>
</h:link>
Unrelated to the concrete question, you should be using <h:graphicImage> instead of <img> as well. This way JSF will ensure that the src is properly set. In your particular case that would be
<h:graphicImage name="img/categories/#{category.name}.jpg"
alt="#{category.name}" class="categoryImage"/>
(note that I replaced ${} by #{}, just to adhere the standard and for the consistency)
You can change from this line:
<a href="<c:url value='category?${category.id}'/>">
to this:
<h:link outcome="category.xhtml?id=#{category.id}" />
<h:link outcome="category">
<f:param name="id" value="#{category.id}" />
</h:link>
<h:outputLink value="category.xhtml?id=#{category.id}" ></h:outputLink>
