Using HtmlTextWriter to Render Server Controls?

由 青春壹個敷衍的年華 提交于 2019-12-23 10:22:36
问题 I'm writing the RenderContents() method of my ASP.NET server control. The method uses an HtmlTextWriter object to render the output content. For the control I'm writing, using the HtmlTextWriter 's methods seems like it will require a lot of lines of code to open and close every tag and add every attribute to the stream. In the end I feel like I'm going to end up with code that is a lot longer than it needs to be. I was thinking that if I used a chainable class such as StringBuilder , my code

Are there any benefits to using HtmlTextWriter if you are not going to benefit from adaptive rendering?

问题 Outside of benefiting from Adaptive Rendering for alternate devices, does it ever make sense to write all of this code: writer.WriteBeginTag("table"); writer.WriteBeginTag("tr"); writer.WriteBeginTag("td"); writer.Write(HtmlTextWriter.TagRightChar); writer.WriteEncodedText(someTextVariable); writer.WriteEndTag("td"); writer.WriteEndTag("tr"); writer.WriteEndTag("table"); When StringBuilder could build the same thing with simply this: sb.Append("<table><tr><td>"); sb.Append(someTextVariable);

问题 Can you use FluentHTML or other alternatives in an web application user control? Can you put a markup file in a System.Web.UI.Control like the System.Web.UI.UserControl but without the burden of the Page object? I would like to reduce the number of lines of the following code: writer.Write(SacrificalMarkupPage.GenerateControlMarkup(new DialogConfirm())); writer.AddAttribute("class", string.Format("ajaxResponse {0}", action)); writer.RenderBeginTag("div"); writer.RenderBeginTag("h4"); writer

Use ASP.Net server control code generation from .ashx

由 余生颓废 提交于 2019-12-08 03:36:42
问题 I'm trying to take an existing bunch of code that was previously on a full .aspx page, and do the same stuff in a .ashx handler. The code created an HtmlTable object, added rows and cells to those rows, then added that html table the .aspx's controls collection, then added it to a div that was already on the page. I am trying to keep the code in tact but instead of putting the control into a div, actually generate the html and I'll return that in a big chunk of text that can be called via

how to display a text with tags in jsp

问题 I want to display a text called "welcome<to>Jsp" In page source also i'm seeing as "welcomeJsp" But in HTML its displaying as "welcomeJsp" alone. Please guide me. 回答1: You have to escape these characters.. welcome<to>Jsp I would advice using Apache's StringEscapeUtils class(available in org.apache.commons.lang ) function escapeHtml() for escaping HTML. StringEscapeUtils.escapeHtml("welcome<to>Jsp") 回答2: "welcome<to>Jsp" > (greater than) - (>) < (less than) - (<) These characters need to be

Fluent interface for rendering HTML

由 江枫思渺然 提交于 2019-11-29 08:40:32
问题 Rendering HTML with the HtmlTextWriter isn't incredibly intuitive in my opinion, but if you're implementing web controls in web forms it's what you have to work with. I thought that it might be possible to create a fluent interface for this that reads a bit more like the HTML it outputs. I would like to know what people think of the syntax that I've come up with so far. public void Render(HtmlTextWriter writer) { writer .Tag(HtmlTextWriterTag.Div, e => e[HtmlTextWriterAttribute.Id, "id"]

How can I get the CheckBoxList selected values, what I have doesn't seem to work C#.NET/VisualWebPart

由 这一生的挚爱 提交于 2019-11-27 04:33:07
I am creating a CheckBoxList in a class file and am using an HTMLTextWriter to render the control. I'm using the following code to store the selected values in a string: string YrStr = ""; for (int i = 0; i < YrChkBox.Items.Count; i++) { if (YrChkBox.Items[i].Selected) { YrStr += YrChkBox.Items[i].Value + ";"; } } I stepped through the code and it doesn't seem to hit the inside of the if statement & the selected value attribute is false every time ... Anyone have an idea of how I can address this? I populate it using the following: YrChkBox.Items.Add(new ListItem("Item 1", "Item1")); In your
