I'm working with an MVC1.0 web app and I've found a bit of an odd anomaly.
I have a search box on the first page (normal text box) and the input from this is passed through to the ViewData and on to the second page.
On the second page, I render a TextArea with this search input text from the ViewData.
Eg:
[Code]....
The problem is, there is an extra line break in the TextArea, just above the original text.
Stranger still is that if I now submit this page and the view is reloaded (after validation fails) - the original string of text has been trimmed and has no line breaks, but the TextArea now has 2 line breaks above the original text.
This can be repeated - every time the page reloads it has another line break.
It's driving me insane - does anyone have an idea on how to fix this?
FYI, you can check it out yourself - on your mobile phone, browse to [URL], punch something in the search box and hit search. You'll notice one line break added the first time the page loads. Then just hit "Find Best Offer" without entering a budget or selecting a category, and you'll see what I mean about the additional line breaks.
I have a WYSIWYG editor set up using ASP.NET MVC. When I post, everything is fine, however when I post and there is an error when the page comes back and shows the errors, the value in the textbox is messed up (it has become un-HTML Encoded) and for form validation reasons, this is fine. My question is this - how, in the controller (preferably), can I change the value of the text in the textarea? Even if I use a ViewData["fieldname"] and set the asp code to:
<%= Html.TextArea("fieldname", ViewData["fieldname"], new { id = "fieldthing", name = "fieldthing", cols = "80", rows = "10" })%>
It still doesn't work because that ViewData is the default value which, after the post, isn't returned to that value, it stays whatever was typed.
So any thoughts on how to edit this value? I tried passing in a new view, but that didn't work either.
I Have a asp.net page with textarea. I am getting data from database and putting it in the textarea. I wanted to grow textarea to expand depending upon the text without scrollbars. I could I achieve this in my asp.net page.

I have a textbox on my page for users to enter input. If they were to type text outside of the box, and then copy it into the textbox, how can I make the textbox able to preserve the style of the text copied into it: italics, bold-faced, etc.?
It currently will convert anything copied into it as plain text.
How can I put text inside textarea by code? and how can I use the control in the code?
View 5 Repliesthere are a few paragraphs separated by line feeds "
" in a textarea, say
Paragraph1 "
"
Paragraph2 "
"
Paragraph3 "
"
what i want to achieve is to process each paragraph into tag. How do you do that? (Need a server side solution) so it looks like
<p> Paragraph 1 </p>
<p> Paragraph 2 </p>
<p> Paragraph 3 </p>
On top of the complexity, if you have a blockquote there
Paragraph1 "
"
<blockquote> "
"
test
</blockquote> "
"
Paragraph2 "
"
Paragraph3 "
"
should come out to look like
<p> Paragraph 1 </p>
<blockquote>
<p>test</p>
</blockquote>
<p> Paragraph 2 </p>
<p> Paragraph 3 </p>
I need to find a way to accurately calculate the byte size of the text inside a particular textarea. I am working in .Net so I have access to those libraries, but I'd prefer a Javascript solution. How many bytes is each character worth? What would be the most efficient way to count and multiply? Or am I missing a better way entirely?
Edit: I'm attempting to determine the download size of a piece of Javascript that has been pasted into a textarea. The closest thing I could find to this is ][URL]. I don't want to just lift their code, especially since I don't fully understand it.
I've written a user control that has a button that a user can click to display an additional DIV. I discovered that it would be nice to make the control remember whether or not the DIV is visible after postback so that when the page reloads, the DIV stays visible if the user wants it that way.
What is a good way to implement this with jQuery at my disposal?
I'm working with the 10.2 version of the DevExpress MVC controls. I have a page hosting a MVCxGridView and I need to preserve the current page when navigating away and back to this particular page.
I can see from the old ASPxGridView documentation that there's a PageIndex property, but this seems to only be accessible from a WebForms/Code Behind/Server Control type context. I'm using MVC and can't figure out how to preserve this page setting.
I've tried the cookie settings with the control but those don't seem to persist for me.
I added a textarea control to my page. Try to reference it in codebehind and it doesn't show in the intellisense. All other controls are though. I noticed that it also doesn't appear in the 'designer.cs' page.

ASP.NET newbie question - fastest fingers!
I have a page that needs to pull some script off the server, including tag info, for the page. Thus:
<html><body>
blahblahblah
<%: Model.TaggedField %>
</body></html>
Problem is, the value of Model.TaggedField may include HTML tags, but the page automatically converts the tag info to <myTag> etc.
What method can I call to make the value of Model.TaggedField be transmitted verbatim to the page?
I have a user control that has some drop down lists. These DDLs are used by the user to filter their product search on my search page. A button is used to post the form and get the results of the product search. Those results are displayed on the results page, which also has the search filter user control on it. I'd like the results page to have the values of the DDLs be preserved from the search page. Example: user selected color of red and size of large on the search page. When the results page is displayed, I'd like the selected color to be red for the color DDL and the size to be large for the size DDL. How can I do this?

Is it possible to create a Custom Control which inherits from System.Web.UI.WebControls.Login and change its layout and add additional controls such as a DropDownList. I have tried various ways to do this by overriding the Render Contents methods but each time I have to recreate the controls which are already present in the main Login control. Is it possible to somehow get a reference to the controls in the parent class and then override the Render Contents method to render the controls how I need them?I would like if at all possible to use the controls and functionality that already exist in the Login control but just change the layout and add in an additional DropDownList control.

I would to define another layout (not using the horrid table) but continue to use all the event handling and the creation of the user of the CreateUserWizard control. Just for reference, the following code doesn't work, and produces an unexpected result not representing my Template at all. The "InstantiateIn" method of the ITemplate is not called.

"How to save the layout of a control in a page to an XML File in ASP.Net"?
I mean to say if there is a Chart Control in an ASPX Page, How would I save the Layout of the ChartControl to an XML File. The XML File should contain all the properties of the Chart Control.
I have a user control which contains a number of child controls. I want to be able to change the layout of the control (i.e. change the markup surrounding the child controls) via a property of the user control, but I don't want to have to duplicate the child controls themselves. This precludes using, say, a MultiView with different versions of the layout in each view, since in that case I'd have to duplicate the controls. I'd also rather use markup than emit the code for the control directly (as you'd do in a server control).
To give a contrived example, say I have a label and a textbox. In one layout, I want the label and textbox to be contained by divs and laid out on top of each other. In an alternate layout, I want them to be contained side by side in a table.
Should I just go ahead and duplicate the controls between each view? It seems like a violation of the DRY principle, but I'm not sure if I have much choice. A partial solution would be making the views of a multiview into naming containers so that I could at least save myself the time of having to prefix the duplicate control IDs with something to make them unique.

Example HTML Layouts (drastically simplified):
<div><table><tr><td>
<p><strong>XXXXXX</strong></p>

versus

Right now, both layouts are rendered. How can I conditionally render one layout and not the other?
I have a user control I'm building that has a table layout with two sets of radio buttons, like:
how I could use a radiobuttonlist for each set of vertical buttons within this layout, unless I used a rowspan on each col, but that seems problematic from a layout perspective? I would rather use a RBL from a programming standpoint.
If I instead used a set of radiobuttons with a groupname for each, how do I get/set the selected button (for each set) from outside the UC?
