View 5 RepliesHow can I put text inside textarea by code? and how can I use the control in the code?
View 5 RepliesI'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 receive a potentially dangerous request.form value was detected from the client when trying to submit text box with html code inside it I turn ValidationRequest="false" in the page and in the web config file also I put this settings <httpRuntime requestValidationMode="2.0"> but I still get the error, I'm using ASP.Net 4 with Visual Studio 2010.
View 2 RepliesHow to create this in Code Behind
<asp:TextBox id="txtarea" runat="server" TextMode="MultiLine" Columns=10/>
I used TextArea in my page
<textarea ID="txtdes" class="DVS2LT">
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.
For some reason I can't get an ajax post action to work if the text inside an textarea contains HTML. In the text area I am entering <h1>test</h1>, when I do that, I can click on the Save button all day if I want, nothing happens. Not sure whats causing this, but it also appears to do it if I don't use the ajax form and just a standard html form.
Here is the code for the controller:

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.
View 2 Repliesi'm loosing my mind.Using ASP.NET in a GridView, amongst other controls, I have the following:
[code]...
there 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>
Ho do I preserve the layout of text in a TextArea control in asp.net ?e.g.
"This is some text:
- line 1 text
- line 2 text
- line 3 text"
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 have a textBox and i set it to MultiLine.i want to know is there some way to get the text inside of text box with a format like, user will type some text in it and mack some brack in text and i want to get the text as like as inside of textBox with those bracks.normaly all with textBox1.Text i get the text in one line
View 2 RepliesI've the Javascript code to do a confirmation before deletion of some records
function confirmDelete()
{
if(confirm('Delete all?'))
{
return true;
}
else
{
return false;
}
}
I've the button code here
<asp:Button ID="btnDelete" runat="server" onClientClick="return confirmDelete();" onClick="btnDelete_click" />
If i've the button outside an update panel (basically i'm using RadAjaxPanel by Telerik) it is working fine. But when the button is inside an ajax panel, even if i click OK for deleting the records the server side code is not called.
underline text in button how?
View 14 Repliesi have a textbox and a checkbox. when the user checks the checbox the text inside the textbox should not be visible to the other user.
how can i achieve this?
My question could be easy but I cannot search it on the net couse I do not know with wich words I need to search it funny haa !
Here is my problem;
I have a button inside a datalist with command name of 'Command1' and '12.09,13,21,True,Here is a string text' The type of it can be changed. it doesnt matter. What I wanna do only matters here ! when I press this button I wanna get value before comma seperately. E.g. someting like that;
decimal Dec1 = 12.09;
int int01 = 13;
int int02 = 21;
Boolean bool1 = True;
string string01 = "Here is a string text";
After I press it I wanna appoint values to those variables.
I am going to use a google map for my project but I need to get the latitude and longitude from label. I will bind these labels so they will be dynamic. I tried the below code but doesn't work at all. Do you know how I can do that.

I have created the user control and it has got one table with few rows in it. One row has got a text box with custom validaor and other row will have check boxes dynamically added through server side.
On the main page, i am loading that user control about 10-15 times depending upon the values from the database.
Is there any way of setting the properties of user control validator on the main page? Text box will only be validated if any check box is checked in the user control.
I am also not able to find the usercontrols through the main page.
I have a scenario that I cannot fit my small brain around at the moment. I have a database driven site that also has a variable amount of user controls that go on to some pages. Some pages do not have user controls associated with them).
So I'm returning the page's body text from the data base like this:
The quick brown fox %ucUserControl1.ascx% jumps over %ucUserControl2.ascx% the fence.
I'm using a text editor for the backend that I'd like to be able to specify a user control in text format (by wrapping it in some sort of tag-- % was used for my above example, but anything will work).
I need to get the text value of a label which is binding a field insiede a datalist. I can get the value by clicking a button but I need to get this value on page load so that I can make it page.title. here is how I am getting it by clicking a button (also button is inside the datalist);
