Which Is Better Span That Runat Server Or Default Lable
Dec 26, 2010
I have a simple asp.net web page that contain a table with about 5 TR and each row have 2 TD .. in the page load I get user data ( 5 property ) and view them in this page the following are first 2 rows :
[code]....
I always used <asp:Label to set value by code but i always notice that label converted in runtime to span so i decided to user span by making him runat=server to be accessed by code, so Which is better to use asp:label or span with runat=server?
I have a span control which I am filling using Jquery. At the page load I want this span say id1 to be invisible and depending on some conditions I am making it visible via jquery itself.
When I make id1 runat = server and try to access id1 from codebehing, then I get an error in Jquery.
Hence I need a way to make id1 invisble at the load time itself.
I have already set id1 = invisble in HTML, But still I see this control on the page till the time jquery fills the entire data.
I have asp.net label called NumberLabel.It is changed from codebehind(asp.net/c#) by calculating the number of rows in an sql server table called "MyTable". Every time a user open this page,the same code/stored procedure is executed to bring the number. Is there a way to to bring the same number for all users and change it only when there is an update in "MyTable".this will optimize a lot time,executions,(SQL server side and webserver side).Does asynchrounous c# exist?or doing that by ajax.
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?
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...
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 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?)
why can't it see this property or the server method RedirectToPayPal? I get a runtime error of :
'ASP.cart_aspx' does not contain a definition for 'RedirectToPayPal' and no extension method 'RedirectToPayPal' accepting a first argument of type 'ASP.cart_aspx' could be found
I am working on Asp.net 2.0.I have 1 problem.In my design <table ><td> <tr> structure is present.<table><tr>< td id="PanJan""< d>< r>< able>runat="server" is not use in this. How to find td, tr , table id when runat server property is not used.
I have to add some ajax to a site, and i can see that in the master page they are using traditional tag <form id="form1" action="ExternalSite.com?a=b" name="test">and I get a tag incorrectly formed when I add a runat="server" within the form tag - but without it I can't have a valid scriptmanager?
I've got the ImageButton wrapped inside a form tag with runat="server" but STILL getting this error at runtime. The form tag is at the very beginning (before my table) and end tag is at the end (after the table).
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?
Since upgrading to VS2010, I've been having issuse up on issues with my apps. Some are pure asp.net web sites, other are webpats that are eventually be converted to a Sharepoint web part.
In one of these webparts, I'm building a tab control on the fly. It fetches data from the table via bll/dal. On my dev box I build this in the code file of the default.aspx file and rendering it in a panel, except that it get the said error. I'm quite sure this is how I've done it in VS2008, so I don't know what is going on here - see my code below.
I have a user control that employs many other controls (GridView, Images, Ajax Tool kit extenders, etc.). When called the RenderControl() method there is the dreaded "<control> must be placed inside a form tag with runat=server". Seems many people have run into this and suggest overriding erifyRenderingInServerForm on the page the control sits in. I tried to do this, but ran into other issues (for example the ajax control tool kit calendar extender started to complain about the extender not being registered properly).
I want to know differences between ASP.Net WebControls and Html Controls (with runat="server" attribute).
I also want to know the possible scenarios where I have to (or want to) prefer Html Controls (with runat=server) in place of asp.net server controls?
In case of some good articles on web, do forward me. But dont forward me the links with differences between webcontrols and html controls, because my question intended for runat="server" attribute.
