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).
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).
wbie here and having a bit of trouble with this export thing.getting the following error message. "Control 'listGrid_ctl14_ctl04' of type 'DataControlImageButton' must be placed inside a form tag with runat=server."
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'm trying to upload files to Amazon. In their simple example, it's an HTML page with a bunch of hidden fields that pass the data needed. The problem is when I create that form in ASP.NET, I, inevitably, end up with a few extra hidden fields i.e. __VIEWSTATE and __VIEWSTATEENCRYPTED at the very least -- and that after setting EnableViewState to false on the page. No matter what I do, these two hidden fields are there. I've read some articles that indicate that I have no way of removing them from the page unless I can remove the <form runat="server"> all together.
I can imagine what the answer will be but I have to ask: is there a way to remove the form tag from an aspx page?
I assume the answer will be "No". Then my follow up question is: how am I going to upload a file to Amazon S3 using an aspx page?
Now, some may suggest that I should use a simple HTML page. Then my issue would be this: there are a whole bunch of parameters I need to get by making an API call first -- they're the ones that end up in those hidden fields. How can I upload my files without losing this server side functionality that I need in order to make the API call?
Here's what that upload form looks like -- according to Amazon:
I am a bit confused about the significance of the <form runat="server"> on a page, and its effect on Page and Control life cycles.
For long, I have eliminated any Postbacks or Viewstate from my web forms. I just use web forms to render (often very very complex) UI to the client (composed of server-side controls as well as ExtJs or jQuery widgets etc).
After the UI renders, all interaction with server is asynchronous through web-services or http handlers. So, lately I have started omitting the <form runat="server"> tage also from my web forms.
And to my surprise, the code has NOT broken. The life-cycle events are generated normally on all controls, they have access to normal ASP.NET processing pipeline, and they render perfect;y. As there are no Postbacks, I do not need ViewState or control events like click etc.
So, can somebody tell me if there's any material difference that <form runat="server"> would make in my scenario, or to ASP.NET page/control life-cycle??
I have a Listview that houses a FileUpload control. However, after using findcontrol the next line of code tries to convert the filename into a string and produces the familar error object reference not found.
Note: I have used identical code in a formview and it works fine.
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 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?
Hello all i have this little issue getting this to work, i have a dropdownlist in asp.net inside a formview and jquery cant find the control im guessing because its inside a form, this is what i got and it works on another page without a formviewi get this errorName 'Country' is not declared
