Write A Custom Rendering Template For The DisplayForm?
Feb 12, 2010I'm trying to write a custom rendering template for use in the DisplayForm of a list whose fields include Title, HeaderImageUrl, Body. I've got the following so far:
<SharePoint:RenderingTemplate ID="NewsListForm" runat="server">
<Template>
<h1><SharePoint:FieldValue FieldName="Title" runat="server"/></h1>
<div>
<p>
<SharePoint:UrlField FieldName="HeaderImageUrl" runat="server"></SharePoint:UrlField>
<SharePoint:RichTextField FieldName="Body" runat="server" />
</p>
</div>
</Template>
</SharePoint:RenderingTemplate>
The HeaderImageUrl field is configured to be an Image URL, but when I use the UrlField control, it renders a link.
I was thinking there might be a way to grab field values and put them in attributes, so something like this:
<asp:Image ImageUrl="<% FieldValue["HeaderImageUrl"] %>" runat="server"/>
If this kind of thing isn't possible, then is there another control in Microsoft.SharePoint.WebControls that would render an image from a URL?

Apr 25, 2010I have a simple HttpHandler that generates a dynamic image based on query string parameters and a custom web control that renders an image tag pointing to the handler as its 'src' attribute. All works fine when run in the web server, but at design timethe control displays as the "missing image" icon (red x in a box). The handler is registered in the web.config with a ".ashx" extension. The RenderContents method in the control looks like this:
output.AddAttribute("src", ResolveUrl(string.Format("~/Sparklines.SparkHandler.ashx?stype=pm&w={0}&h={1}&sv={2}&ev={3}&cv={4}&sc={5}&ec={6}&mc={7}&gs={8}",

Web Forms :: Rendering Custom Controls And Viewstate?
Feb 3, 2010When developing custom controls and using them in ASP.NET, what are the answers to the following?
- What events to use for loading and saving viewstate for controls (is this the same thing as control state?) and also for custom controls?
- Similarly, which events should I use to render controls? Is this PreInit and Load? Is this the same for custom controls?

Custom Server Controls :: Dynamic User Control Rendering - How To Do It
Jun 8, 2010I am using two user controls in my page. The controls are loaded dynamically one at a time. I'm just referencing the user controls in the page and loading them dynamically using 'LoadControl()'. Everything is working fine till now and the user can switch the controls one another.
Here the issue I found is eventhough the controls are working as expected and the data is visible, the rendered HTML contains only the first loaded user control's markup.
Even if the current control displayed is 'usercontrol2', the source shows 'usercontrol1' markup. How can I force the page to render 'usercontrol2' markup and remove 'usercontrol1' markup while loading'usercontrol2'?
How To Use The Name Of The Property That Rendering Inside Template
Apr 29, 2010I'm reviewing new features of ASP.NET MVC 2.0. During the review i found really interesting using Templated Helpers. As they described it, the primary reason of using them is to provide common way of how some datatypes should be rendered. Now i want to use this way in my project for DateTime datatype My project was written for the MVC 1.0 so generating of editbox is looking like this:
<%= Html.TextBox("BirthDate", Model.BirthDate, new { maxlength = 10, size = 10, @class = "BirthDate-date" })%>
<script type="text/javascript">
$(document).ready(function() {
$(".BirthDate-date").datepicker({ showOn: 'button', buttonImage: '<%=Url.Content("~/images/i_calendar.gif") %>', buttonImageOnly: true });
});
</script>
Now i want to use Template Helper, so i want to have above code once i type next sentence:
<%=Html.EditorFor(f=>f.BirthDate) %>
According to the manual I create DataTime.ascx partial view inside Shared/EditorTemplates folder. I put there above code and stacked with the problem. How can i pass the name of the property that I'm rendering with template helper? As you can see from my example, i really need it, since I'm using the name of the property to specify data value and parameter name that will be send during the POST requsest. Also, I'm using it to generate class name for JS calendar building. I tried to remove my partial class for template helper and made MVC to generate its default behavior. Here what it generated for me:
<input type="text" value="04/29/2010" name="LoanApplicationDays" id="LoanApplicationDays" class="text-box single-line">
As you can see, it used the name of the property for "name" and "id" attributes. This example let me to presume that Template Helper knows about the name of the property. So, there should be some way of how to use it in custom implementation.
Custom Server Controls :: Rendering Controls Via Loop Inside Render
Nov 11, 2010I am creatin a server control where some controls are being rendered inside `protected override void Render(HtmlTextWriter writer)`
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo1");
writer.AddAttribute(HtmlTextWriterAttribute.Value, "Button1");
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag(); //button
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo2");
writer.AddAttribute(HtmlTextWriterAttribute.Value, "Button2");
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag(); //button
This way buttons are rendered on design view as well. The problem is that number of buttons to render is dynamic based on data in xml file (even if the data was static, the number of button is about 12 and I don't think it is wise to copy paste the same code above 6 times...). I thought by using loop for that:
int i = 1;
foreach (Button button in tb.Items)
{
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo" + i);
writer.AddAttribute(HtmlTextWriterAttribute.Value, button.ButtonValue);
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag(); //button
i++;
}
tb is defined in OnLoad; On run time it works, but on design time I get error: > Error rendering control. And control is not being rendered.
Custom Server Controls :: Child Controls Of Extended GridView Rendering As Plain HTML?
Mar 7, 2011I have been trying to implement an extended GridView that eventually will include a panel with a number of filter options outside of the grid iteself.
As a test I have added a dropdownlist and a linkbutton but when these are rendered to the page they are rendered as plain HTML with none of the javascript or ids that are generated for server controls as a consequence the postback event is not fired when a dropdownlist item changes and the linkbutton is rendered as plain text.

Mar 13, 2010i create a custom control which can hold some templates, such as Header, Body Footer, etc.

i tried to use smarttags to allow the user to edit each of the templates, which worked pretty well. what i could not get working was to add a template if it has not been in the control. eg. add a header-template to the control above. i tried using the RootDesigner.AddControlToDocument() function of my controldesigner. but this function gives me an error, telling me the control i'm going to add the template (i used a new HtmlGenericControl("HeaderTemplate") as new Control) to is not valid. (i can't give the exact error message, cause i use a german version of visual studio 2008) i've been searching the web for nearly half a day now, but i did'nt find a working solution for my problem.
Forms Data Controls :: How To Create Own Custom Pager Template

To make application faster, I want to select not all records, but as many as fit in a GridView page. But in this case, the pager section doesn't show up. Could anybody suggest how I can fix that? Some people say I should do my own pager template, but I don't know neither how to make it, nor how to use it.

Custom Server Controls :: How To Make Controls Inside A Template Visible To Code-behind
Nov 27, 2010I have created a custom control that implements Templates (based on Panel controls) ... I can do a FindControl to locate imbedded controls. This allows me to get and set values in the imbedded controls, but I want to be able to reference the imbedded controls like they are properties of the associated panel. Here is a sample of how my custom control now works:
<cc:CustomControl ID="myCustomControl" runat="server">
<PanelTemplate>
<asp:TextBox ID="myTextBox" runat="server"></asp:TextBox>
</PanelTemplate>
</cc:CustomControl>
I can do the following (where my custom control has given the panel hosting the template the name "myPanel"):
Dim txt As TextBox = myCustomControl.myPanel.FindControl("myTextBox")
txt.Text = "Some text to put in TextBox"
What I want to do is:
myCustomControl.myPanel.myTextBox.Text = "Some text to put in TextBox"
Custom Server Controls :: Find Controls Present Inside Template Field?
Jan 11, 2011I am writing a custom control and implementing ITemplate in it. The code that I am using can be reviewed at the following link: http://msdn.microsoft.com/en-us/library/ms178657.aspx
Under the Template field, I would only like to allow controls of specific type only, say LinkButton and TextBox. If any control(s) present inside Template is anything except LinkButton or TextBox, an error should be thrown. I am wondering how can I check it programmatically inside custom control. The problem is that there is no collection available that lists all the controls that of Template (or may be I am not aware of it.)
