Accessing Html Controls Within File From Server Side C#
Feb 27, 2010
Following code is an example, I just want to know if this can be done. I have an test.aspx file with this server side include tag;
<!--#include file="listOfCountries.htm" -->
Within listOfCountries.htm, I have:
<html>
<div>
<select id="countryList" runat="server">
<option></option>
...
</select>
</div>
</html>
Now, Is there a way to access "countryList" in test.aspx.cs file? On another note, say I didn't have the #include "Countries.htm" in test.aspx, is it possible to access the controls within Countries.htm from test.aspx.cs ? (i.e. accessing an external html file controls in cs)
I am using the <input type="file" /> tag to upload a file to the server. How do I access the file at the server side and store it at the server? (The file is an image file)The client side code is :
I created a aesthetic control that creates two lists in seperate div tags organized with a table for each. The control always the user to click on the img tag associated with each item to move it between the two lists. I am doing all the movement between the lists via javascript and want to have a good method for obtaining the values and storing them in two lists upon Postback. I thought of doing something like storing the indexes/classes in hidden values and them reading them to find the items but that seems messy. Also, thought there might be a clever way of traversing the DOM via FindControl() but not sure. Any input would be great.
One other thing is that this is not a composite control. All the tags are being rendered in the RenderContents() method. So I don't know if there is a way to even tack on a runat="server" attribute to an elem like I normally would if I wanted code behind access to an html element.
Here is the HTML that is generated. I don't think there is need to post the server side code since it does nothing more than generate the html at this point.
The idea is that a pure html table will be generated on the client side. (using jQuery to add dynamic new rows to the table when the user clicks a button). These rows contain textboxes, dropdownlists, checkboxes and other input controls. When the user clicks a button, a PostBack is triggered in which I need to access this data from the table on server side, validate it and perform other actions on it.
I'm able to perform the client side and access the table data on server side by adding runat="server" to the table tag. However, I only see the initial table rows (not the ones added through JavaScript) and I have troubles retrieving the different inputs from the rows. put me in the right direction?? Or someone offering a better solution to the problem?
i can use escape() and unescape() functions by Client side easily, but the problem when i have use escape() method for peice of HTML , then i dont know how to unescape this piece of HTMl By Server Side not By Client Side. how i can unescape (escapped HTML) by server side?
I want to enable comment posting on my page, so i need to execute some html encoding before post is sent and inserted into a database. What is the ideal side for this? Sever side(I work with asp.net) or client side (javascript)?
i have a <div> named 'mydiv' on a web page and have set it's runat property as <server> so it is visible within
my vb.net server side code.
i can see the mydiv within the server side code.
my question:
how do i adjust the height/style of the <div> withion the vb.net code so that whe the page is posted back the new height/style settings apply. how do i get to the style properties server side?
The more I think about it, the more confused I get. Is this even an ASP.NET question? Maybe it's a Silverlight question, or maybe it's an IIS question. Maybe it's a C/C++ question?!
I rent a server from a server farm. I also subscribe to a security service that streams, over the Internet, once every three seconds, via https, a series of JPG photos from four outdoor security cameras at a certain location.
I want to collect these photos on my rented server (server side). Keep in mind these are photos, not video, though after two weeks of streaming you can get around 50 GB of photos I am told, so I'll have to track storage consumed and delete the old ones, but that's a minor issue.
I researched how to capture streaming photos in ASP.NET and found nothing. I researched it in Silverlight and found a number of links for client side video chatting (a new feature supported by Silverlight 4) both multi-user and single-user, assuming they have web-cams attached to their client side PC. Not quite the same problem as what I have, since I don't care to attach any process to the four security cameras (the security company already wrote the software to do that, and is streaming it live). I just want to know how I can capture and store the streamed photos on my server.
I have a table that the user can add rows to through javascript by clicking on a "add rows button". In each row there are two columns one with a dropdown list and the other a text box. The dropdown list is populated with data through a sub on server side code.I need to be able to insert the data from each row into a table but I'm unable to do this. I clicked on my "add rows button" to add several rows and then did a test to see how many rows the table was returning on the server side and it did not include the five rows I added .. only the header row.If there is a better way to allow users to dynamically add rows to a table and then access the dynamically created table on the server then I'm all ears!
after trying alot and searching here and there i decided to post it here. I have my aspx page. at the top pf that page a html header is included, that html header contains a html select control with runat="server". i populated it with dataset, i also implimented onserverchange even successfully. no on my main aspx page i have anothe asp dropdownlist control. what i want is that whenever dropdownlist server selected index changed the value of html select control in my header also chang. I code in dropdownlist_selectedindex change like this
I have a page with a table and two button with the names (Submit and Add Rows) When I click on Add Row a new row will be added to a page(This is achieved using javascript), when I click on submit button I will be doing server side validation. If I found any error the error will be displayed on the page. During this process the controls which were added by me were loosing its state. As a result I need to add the rows once again and need to fill the data and click on submit button. Can any one let me know how to avoid this and see that the controls donot loose their states. So that there is no need for me to create rows once again if any validation fails on the server side.
To my understanding the clinet side can only send data to the server either by get or post. so basically either through query string (get) or through body of the page (post).
So when we upload a file from client machine and send it to server, what exactly is happening behind the scenes? are we doing a post?
I wanted to know whether this is possible or not. I have a page with a div. I populate div at run time with a HTML table I wanted to access that table to get the data back.
I am trying with ParseControl() method... Not success Yet.
I have the following html that I want to convert it to use asp.net web control
[Code]....
What will be the best approach? I thought about using asp:ImageButton, but it only has a PostBackUrl, sounds like it does a http post to default.aspx, but the html simply do a http get to default.aspx .
I've looked at replacing the ImageButton web control with a simpler HTML img tag (which is what the PopBox documentation suggests). Yet, I don't know how to populate an <img> tag from the CodeBehind file. Here is a typical statement which sets the .SRC property from an ASP.Net dataset row:
Visual Studio 2008 does not complain about this declaration above but in the codebehind file, how would I address this so I could populate the .Src attribute.
Intellisense, cannot even "see" this Me.imgPicture.src = theUrl 'this won't compile...
I added this at the top of the codebehind but seemed to have no effect:
Now I want to create a list like below in the aspx page, created from the database. I have done the work of keeping all the tags and tagURL from the database in a dataset. But I have no idea how to create dynamic HTML list or asp.net list from database.
I am making use of XSLT in showing a XML form. But in XSLT file along with the path of XML, I have a checkbox and a textbox input html control type. My question is how can I access these html control input value in the server page?
