In other words, why can't I do this:
<a id="projectsButton"
visible=<%= someFunctionWhichEvalsToFalse() ? false : true %>>
</a>
It seems to do nothing. I checked this by switching the false and true.
I have a FormView which contains a table and a TextBox:
<TR>
<td>CastomerName:</td>
<td>[code]....
and it works good.I changed the code to have a possibility for changing the row visibility. So, I added the row ID and runat="server". Changes are bolded:
<tr ID="RowCustomerName" runat="server">
<td>CastomerName:</td>
<td>[code]....
After the runat="server" has been added to the <TR> then Bind() does not work. It reads the field value properly but writes NULL value. So, Bind() does not work or works bad. I tested the following:
1. When runat="server" is removed, than Bind() works good. The text from TextBox control is written to the database as expected.
2. When runat="server" is set and I set a default value in the ObjectDataSource - the default value is written to the database, so it means that path form ObjectDataSource works good and it means that text from TextBoxControl is not pased to the ObjectDataSource.
3. When runat="server" is set then text from TextBox.Text is never written to the database, instead null value is written.
including runat="server" makes Bind() works bad.
Its simple if I have an ASP.net page with an ASP.net linkbutton / hyperlink and I obtain a value from say a SQL Database and I store it in the label...
For example:
this.myLabel.Text = someValueReturnedFromADatabase
This is simple because it goes right to the code behind page and set the text value to the value returned from my database (aside from going into more details with data access layer, etc).
What I was wondering is what if I dont want to use an ASP.net linkbutton and I simply want to use an HTML link button (as I need to call the jquery fade function). How would I set the value someValueReturnedFromADatabase to a control that is not runat=server?
I have the following code:

How to access to an HTML control runat server from JavaScript
I have this problem - I'm working on an ASP.NET AJAX-application on a server without .net 3.5 which means I can't use ListView (BOO!).
I decided to simply do the ugly way of making a table and giving the tbody an ID and a runat server tag, and put HtmlControls inside from the codebehind (btw - this is a usercontrol, in case it makes a difference).
This all works fine - until the page does a partial postback - and all the elements disappear, since the tag is runat server I assume it requires to be repopulated in the page load.
Is there no way to actually persist the data on partial postback? And only have the content of the control change when I say so in the back end?
I guess I could save the content in a session object upon populating the control, and just repopulate in the Page_Load with the session object - but I was hoping there was a better way to do this?

View 6 RepliesI am learning asp.net using Visual web developer 2008 express.
I have an image control with the html code below
<div class="Header">
<asp:Image ID="image1" runat="server"
ImageUrl="D:/Master/test.jpg" Width="500" Height="300"
AlternateText="UNRA Fort Portal Intranet"/>
</div>
In design view, the image shows but when i run the app, the image is not shown. Only the alternate text is displayed.
The css code code as below.
.Header
{
top:10px;
left:20px;
position:absolute;
width:800px;
background-image:URL(D:/Master/test.jpg);
background-repeat:repeat-x;
}
I have a masterpage (which we will call 'default'). This contains a second page (web user control) -'second'. And finally a third 'print' page. The 'print' page is also a web user control, however, it merely has a placeholder that contains the 'second' page.Is there a way I can add a control to the 'second' page - such as a literal, and only have it visible on the 'print' page?
View 1 RepliesHOWTO create ASP.NET C# controls on server side for posted data that had no runat=server on the client.
I have processes needing to post files to a ASP.NET application. These processes must post without runat=server as such:
<form ~~~~ to some ASP.NET/C#/aspx page>
<input type=file name=MY_FILE ~~~>
</form>
On the ASP.NET page, in the Page_Load I would code somethign like this:
[URL]
Here is the trick, the control "fileLIST_FILE" does not exist because the HTML does not have runat=server on it.
If the client did have runat=server the designer.cs would have somethign liek this:
System.Web.UI.HtmlControls.HtmlInputFile fileLIST_FILE;
With all that said, I want to make "fileLIST_FILE" on the fly inside Page_Load fromt he posted name of "MY_FILE".
do not focus on the fact that this is a file upload. I would like to know how to do this for any posted FORM data.
When I use an anchor tag on an aspx page as below,
<a href="~/pages/page.aspx?id=<%= ServervariableName %>"> test </a>
it will get the variable value correctly assigned to id but it won't route the page correctly as the ~ will not be evaluated without the runat="server" attribute on the 'a' tag. But once I add the runat server attribute, it does not evaluate the servervariable name anymore.. how this works or what I should do to take care of both?
The AutoPostBack doesn't seem to work. Anything I am leaving out?

i'm trying make some stuffs in jQuery using asp.net. but the id from runat="server" is not the same as the id used in html.
i'm used to use this to get the id from this situation:
$("#<%=txtTest.ClientID%>").val();
but in this case. it does not work, and i'm clueless why.

m having a object tag on the page.how can make runat="server".so that i can add data dynamically to it.
View 4 RepliesI have created a new Web project (.Net 3.5) and I've removed the original Default page in favour of creating a Master page and then recreating a Default with Master page. All worked lovely. Now, when I add my controls inside of the ContentPlaceHolder on the Default page, I get compiler errors when I try to access the controls from the CodeFile:
Error 4 '_Default' does not contain a definition for 'FirstName' and no extension method 'FirstName' accepting a first argument of type '_Default' could be found (are you missing a using directive or an assembly reference?)
My declaration of the control:
<asp:TextBox runat="server" ID="FirstName" />
EDIT
Page declaration:
<%@ Page Title="" Language="C#" MasterPageFile="~/Master/MasterPage.Master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
Code-behind:string firstname = FirstName.Text;
Is there a way I can make a div runat server? So i can turn it into a control? In asp.net?
