I have a webforms control, my:Repeater, that is an asp:Repeater. I want to make a default template, like:
[code]....
I want this template to be in some file not writable by the user. If the user just do
<my:Repeater/>
then it should use my default template. However, the user may override one or more of <HeaderTemplate>,
<ItemTemplate> or <FooterTemplate>.
Is this possible, and how can I achieve it?
If I have a custom user control (say, MyCustomControl.ascx) which contains a number of other controls including a repeater, is there any way to expose that repeater's templates as templates for MyCustomControl?
For example, I would want to be able to do this:
[code]....
There could potentially be more than one repeater or other templated controls within the parent control, in which case I would like to be able to expose all of those templates for all of the controls in the same way.
My first thought was to simply expose the repeater's templates as ITemplate properties on MyCustomControl, but that didn't work since there's no (obvious) way to access the repeater's DataItem from the templates doing it that way.
I am currently evaluating the use of asp.net and MVC for a new project (vs. web part or web form pattern). While I really like the MVC pattern and the ability to abstract the code from the UI. I have a specific requiremt to create a custom control that returns data in a pre-defined format. As an example for this project I need to have data returned in a listbox control where there listboxt items contain an image and then values from the DAL. I want to have control over where the image and values from the DAL appear in the listbox control. Using WPF I have done this using Data templates. Is this possible using ASP.NET and the MVC pattern or is this only possible using a web form/ web part pattern?
Update In doing some more reading it appears that I can control how the data would be rendered in the view using markup: As an example if I have a collection (products) that returns image, name, description, price I can render this in the view by writing:
<ul id="products">
<% foreach (var p in products)
{ %>
<li>
<%:p.image%>
<%:p.name%>
<br />
<%:p.description%>
<%:p.price%>
</li>
<%} %>
</ul>
I use the FormView control quite a bit, but I wish I had more control over the default templates.
When I drag a FormView from the toolbox onto my page and point it to a DataSource control it prepopulates the ItemTemplate, EditItemTemplate and InsertItemTemplates, but it doesn't do it very well.
For example, the InsertItemTemplate looks like this by default:
<InsertItemTemplate>
id:
<asp:TextBox ID="IDTextBox" runat="server" Text='<%# Bind("id") %>' />
<br />
Name:
<asp:TextBox ID="NameTextBox" runat="server" Text='<%# Bind("Name") %>' />
...
</InsertItemTemplate>
But what I would prefer is a good old fashioned html table
<InsertItemTemplate>
<table>
<tr>
<td>
id:
</td>
<td>
<asp:TextBox ID="IDTextBox" runat="server" Text='<%# Bind("id") %>' />
</td>
<tr>
...
</table>
</insertItemTemplate>
I know I can use a DetailsView to get a table rendered out, but I end up modifying the form so much that I prefer to use the FormView. It's just that I would like Visual Studio to start me out a bit closer to where I want to end up.
I would imagine that there is a T4 template somewhere in the guts of VS that I might be able to modify to get this done.
I installed the dotnetnuke starter kit for VS 2008 and now when I go to create a new website or project, the only template is a dotnetnuke website. I have lost all of the default templates that come with VS. Is there some way I can restore those?
View 3 Repliesi am working on a project in which i have to create newsletters. We wish to give user functionality of editing the complete layout ( drag and drop if possible) I am able to achieve drag and drop with web parts but can't customise them much like adding richtext box and saving multiple copies of same page with different layouts. I then wish to enable user to send the html only part of page which contains dynamic layout.
View 1 RepliesI've got a repeater control containing comments. I'm about to implement ajax paging to it. I was opting to use the updatepanel (conditionally) for this thing, but I guess it's going to get kinda slow in production environment (Each time about 20 rows will be visible). I want to keep the repeater control since it contains other controls as well so I can't use a js (templates)/json approach.
View 1 RepliesThis is probably a dumb question, but I have to ask because I spend so much time editing my formviews and listviews. Is there a way to edit the default template setup for these controls, in the code or somewhere? When you drag them over you get the default text with textbox column names; then I spend over 30 mins editing each to look the way I want it to.
I know I can create standard templates for WebForms and save them as Exported Templates.
And is it possible to edit the default control when you drag them on to the page, to list certain attributes automatically. example (validation controls you always have to add ControltoValidate I would like to drag mine onto the page and it say controltovalidate="" and then all I do is fill in the blank. Intellisense is fine, but sometimes you get brain freeze after hours of web design and forget the needed attribute and you have all to go through all of the errors and mistakes.
The ultimate would be, to drag a FormView Control and when you Refresh the Schema, you get textboxes, label controls instead of text for column name, and divs for forms, and Image Buttons , I am sure there is an XML file that runs the code that you can edit or something.

ASP Developers, When you develop the next ServicePack allow us to edit or create default templates to customize the default templates, in VS and VWD.
Using Visual Web Developer 2010 Express. I was used to creating a web app anytime and I would get a default page for starters and be happy. But today I find that when I pick either the ASP.NET Web Site or ASP.NET Web Application templates I get site.master and a bunch of site admin files that I don't want. Alternately when I select the empty versions of those templates, I get almost nothing at all. An almost empty web.config page and no Default.aspx page. There is nothing magical about having a default.aspx page in place, but it is an indicator of a change when I can only get a virtually completely empty website or a website with a bunch of bells and whistles I don't want.
Also, for some reason, when I create a new app or website as just noted, in the Solution Explorer I get aspx.designer.cs files showing as well as web.config files for both debug and release. Somehow some settings and templates must have changed, or am I missing something here? How can I get my settings/templates to go back to the way they were?

View 7 RepliesThere's this repeater...
<asp:Repeater ID="myRepeater" OnItemCommand="rpt1_ItemCommand" runat="server" OnItemDataBound="rpt1_OnItemDataBound">

What I want is that when user clicks on any of the "lnk1" link button in the lsit that repeater renders,
the link should be replaced with the label "label1"..ie when the user clicks on "Make Default" link, it should be replaced with "Yes" label
Now when I click 2 link buttons, both get their label "Yes" displayed where as I want only one link button to display Yes ie the one which has been clciked and rest of the items should display "Make Default" link button only.
ie Only ONE item should be displaying "Yes" label...now how do I iterate through the repeater items to set only ONE item as default and not multiple ??

I have nested a repeater control in Gridview. Right now it is showing gridview rows and repeater header for every case(whether data is there or not for that particular grid view row in the repeater control). I want to hide the gridview row and repeater control header when there is no data present for that particular gridview row. That case I handled at code level by filtering the resulted data table.
Now the another problem I am facing: I have allowed the paging on the gridview i.e. pagesize 3. When page loads it works fine, but when I go to page 2 then it generates following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Below is the code to fill the grid, paging and fill repeater on rowdatabound event of grid.

I am trying to secure very mixed content that is located in an ASP.NET directory. For purposes of this question, it can be ~/MyApp/.
I want all of the content in the directory and its subdirectories restricted to authenticated users. The default.aspx page, though, should be accessible to everyone. This is the web.config in that directory:
[Code]....
Now if you are an unauthenticated user, everything works fine if you request [code]....
The problem occurs in that visitors do not always request "Default.aspx". We have a default document configured so that they get Default.aspx even if they just request "/MyApp". An authenticated user works fine, but an unauthenticated user is directed to the login page.
Now I know that essentially this happens because even though the request for "/MyApp/" will actually end up serving up "/MyApp/Default.aspx", the security system is only checking for "/MyApp/" since that is what I requested. That is then getting the default security for the directory.
How can you configure an exception to allow access when no particular file is requested in the directory??
Is there some dependency between DefaultDocumentModule and UrlAuthorizationModule? In this environment, the UrlAuthorizationModule has been removed and re-added in order to make sure it fires for non-managed requests. I would not expect that to change the order of execution, though, since UrlAuthorizationModule usually goes after DefaultDocument.
A workaround could be to set up the opposite security with the directory being open, and then trying to secure individual files. Because of the (changing) number of files, and extensions, etc, and the fact that you cannot use wildcards in a <location>, this is not really a workable solution for me.
the default ASP.NET Forms Authentication cookie sets it's name as ".ASPXAUTH". Notice the first character is a period? Is there a particular reason for this? Like, does this have an impact on domain names or subdomains for the target domain.
Or is it purely some random thing an MS dev person came up with (maybe to help out the ordering of the cookies, when they were debugging or something .. as text with periods prolly get listed before other strings)?

View 3 RepliesI have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
