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?
If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.
I am trying to set a hidden type value to x on Server Side and then access it with Javascript. I have tried multiple ways to accomplish this.
At the basic level this is what I am trying to do.
Aspx page
<asp:HiddenField ID="HidRowNumber" runat="server" />
CS Page
In IsPostBack
HidRowNumber.Value = EFileRowNumber.Text;
Javscript
var status = document.getElementById("<%= HidRowNumber.ClientID %>").value;
When I am debugin it say it HidRowNumber's Value has changed to x but when I access the value with JS it always returns ''.
I have a public property defined in code behind of a user control. I want to toggle visibility of controls in the markup based on the property's value.
However, using the following syntax:
<td style="display:<%#(Container.PageControlMode == PageControlMode. PageMode.Wizard) ? "none" : "inline" %;">
I have the following property in my code behind:
public PageMode PageControlMode { get; set; }
Does not work and generate errors.
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?
If I have a standard HTML textbox
[Code]....
but got a readonly error.
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!
View 3 RepliesIs it possible to either access the properties, such as 'url', of a embedded media player object server side to change them? Or possibly dynamically create a new media player object with a different 'url' each time?
I am trying to change the property based off of a selectedindexchanging event of a gridview object.
in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX
If I have a standard HTML textbox: I can retrieve the value using Request.Form. But how do I go about populating this textbox from the server-side? I tried Request.Form["txtTest"] = "blah"; but got a readonly error.

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)
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 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 :

<div>
<input type="file" id="file" onchange="preview(this)" />

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.
<div class="DualListPanel" id="test1">
<div key="test1_Unassigned">
<table class="DLPTable">
<tr>
<td>Item 1</td>
<td><img src="..." onclick="Move(this)" /></td>
</tr>
<tr>
<td>Item 2</td>
<td><img src="..." onclick="Move(this)" /></td>
</tr>
</table>
</div>
<div key="test1_Assigned">
<table class="DLPTable">
</table
</div>
</div>
I have a page where i am creating a number of <span> elements using clientside code.
I am creating the elements using jquery like this

But this returns a null object everytime. I have tried this code on a span that is on the page at the beginning and it works so i guess its something to do with how im creating the control dynamically.
In my application, I use nested master pages. In the main.master which is the top level, all encompossing master page, I have some properties. I want to set the value of this property from a user control embedded into the page which is using master page which is embedded into main.master. To clarify further, here's the hierarchy
main.master
content.master
some_page.aspx
myUserControl.ascx
The property is mpProperty1 which is in main.master. How do I access and set the value of this property from my user control?

View 2 RepliesI am writing my own captcha generator page using an aspx form that generates an image.
In the form that displays the captcha I have the following img tag -
<asp:Image ID="Image1" runat="server" ImageUrl="~/captcha.aspx" />
and things works well.
What I want to do is use the image tag with width and height specified properties -

and in my captcha.aspx read the width and height properties in my captcha generator vb script.
How can I access the width and height from my captcha generator vb script?
I am currently working on a page that displays a set of questions as retrieved from an XML source. I can print the questions out fine by using a ListView and the ItemDataBound event. On PostBack it seems I can get some property values (Text), but not others (ID). I need to get the ID so I can match up the answer to the appropriate question.
Here is the ListView:

Executing Server side code using Javascript. Here is the solution.In the Asp.net forums, I often see the question asked, "Can I call server-side code from the client/JavaScript?" Almost invariably, the responses given are "No, the client cannot access the server," or "You can only use WebMethods or PageMethods." The first response is not entirely correct, and unfortunately, WebMethods and PageMethods are static methods and therefore have no way to directly access the page.This is why I present to you the following "hack". I call it a hack because there really should be some way built into the ASP.NET AJAX Extensions that allow this approach directly. Instead, it relies on using controls in a manner that they aren't necessarily intended in order to obtain the desired result. But this "hack" does have a redeeming quality—it's incredibly easy.The Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>

In my online shoping project i m uploading images in my Image folder
now i want to delete image when it is deleted from database.
I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?
