Forms Data Controls :: Web Page Rendering In Compatabilty Mode?
Jan 5, 2011
I am currently developing a site in the .Net Framework 3.5. The site works correctly except when the user selects the Compatabilty view. I am unsure of how to make the page render properly in compatabilty mode. I have problems with the repeater displaying data correctly from the sql Server. I also have a dynamic menu that is called from the server this too also renders incorrectly in compatability mode. I am a new asp.net developer and I havent come across this type of problem before. Basically I want the site to be correctly viewable in IE 7 and 6.
The method GetDesignTimeHtml of the ControlDesigner class should return html markup that will be shown on the page in design time. My problem is that control looks different in different versions of the visual studio. What is the rendering engine visual studio use to render control in design mode?
I've migrated a test site to asp.net 4.0 to take advantage of the list renderingmode for a menu. Having the UL and LI should be easier than the table rendering.I'm making progress, (still have work to do, just ignore the odd border) however one issue continues to plague the testing. IN IE 6,7,8, as the page is rendering, it appears the menu is flickering and trying to render as a vertical menu instead of the correct orientation which is horizontal. In Moz, Chrome, Sarafi, Opera, I don't get this behavior.
The menu is styled with CSS however I'm not opposed to adding some corrective code directly to the masterpage that holds the menu. I'd apprecate a suggestion as to how to solve this because as it is, it is not usable.Here is the link to the test site. http://testbeachcrab.net.serv7.temphostspace.com/default.aspx
I have several datalist controls inside a panel control.
When I do a databind on the "movie" datalist, data is populated. I can see during the debugging on the aspx page that it goes into the label controls and binds the data.
When I do a databind on the "alacarte" datalist, the data isn't populated even though before doing the databind I validate that there is a record inside the generic collection that I use for each separate type of datalist. When the databind occurs, it goes thru the alacarte datalist and does the databinding to the fields, but when the page renders, it doesn't produce any output inside this datalist.
The code behind below is the databinding for the movie datalist.
DataList grdMovies = ShoppingCart1.FindControl("grdMovies") as DataList; grdMovies.DataSource = lstMovies; grdMovies.DataBind();
The code behind below is the databinding for the alacarte datalist. I verified that there is a record inside the lstAlacarte collection with the same field names that are in the html for the alacarte section during the databinding.
DataList grdCartAlaCartePgming = ShoppingCart1.FindControl("grdCartAlacartePgming") as DataList; grdCartAlaCartePgming.DataSource = lstAlacarte; grdCartAlaCartePgming.DataBind();
Below is the html on the aspx page for the above controls. I included all of the html so as to see if there is anything I'm doing wrong. I even placed the words "desc" and "price" to see if that would render and it did not.
I hate tables - don't want to use tables, unless I have tabular data to display. A menu is not tabular data (as far as I am concerned.) I was elated to see that in asp.net 4 - the menu control renders as a <ul> <li>, instead of as a table. However - try as I might, I can not get a horizontally orientated Menu to split into even columns, and text align center. FYI - I don't use fixed width - so I can't just set a width to 1000 - and separate it into even columns. Besides that, I want it to change width dynamically, based on the number of "columns (menuItems)" there are. Is it possible to spread out the <li> menu items evenly across the space I provide for them in their containing div or will I have to quite using menu controls, and start using JQuery Menu's?

I have a simple HttpHandler that generates a dynamic image based on query string parameters and a custom web control that renders an image tag pointing to the handler as its 'src' attribute. All works fine when run in the web server, but at design timethe control displays as the "missing image" icon (red x in a box). The handler is registered in the web.config with a ".ashx" extension. The RenderContents method in the control looks like this:
So, I'm trying to use form view in insert mode on a dedicated aspx page. So when a user clicks "Add New" from the main GridView page, it will take the user to an Insert.aspx page that will be in Insert mode ready to collect information.
Here's what I have so far, and all I get is a blank page when I try to run it.
I have a FormView at the very bottom of the page in insert/edit mode. When I click insert/update button, the whole page reload and the pointer does not keep within the Formview but go to the very top of the page far away from the desired FormView.
What can I do here to prevent cursor going outside the Formview ? Is it I can use update panel ? What and where I should use the tags ? Or there are other better way ?
I seem to be experiencing a problem with the modal popup on a page. I'm forcing IE 8 to render with the IE 5 engine using: <meta http-equiv="X-UA-Compatible" content="IE=5" /> as a quick fix while true IE 8 compatibility is being worked on.
Problem is the modal popup doesn't really work. It just displays at the bottom of the page, and when I scroll up/down, the page gets wider and wider..
I have a "report" the users can run it basically creates a simple gridview. In the gridview the user can click on a claim ID. The claim id is then passed via url querystring to a claim management page. The claim management page uses a listview to display the various claims and allow users to edit them. I want to use the claim id passed in the url to locate the listview row to open in edit mode, so the user can make changes / alterations to the claim.
I have a gridview on Contacts.aspx. From this page, I want an "Add New Contact" ImageButton to open the Formview in the ContactDetails.aspx page in Insert mode....

I'm rewriting my website in aspx to pull text from a SQl server and pop it up in a modal. I have everything working fine, but when I was using plain asp and HTML tables, I was able to format some of the text in the database using HTML tags, and they would render to screen. Is there anyway to do the same thing when using the following:

I am having an issue with the gridview in ASP.NET. Everything works well when running from IDE in both debug and without debug. When I publish to IIS I have a gridview that I use in two places. It works fine in one place but not the other. In one instance I am using an IFRAME tag to display the page that uses this data grid. When I first load it it works fine, I can click on a row. But after clicking on that row after the first postback, I can no longer get it to postback again on future clicks. I used firefly and after clicking the first time on the grid, the tags for the table are not rendered though I can clearly see the grid. Confused... Here is the rendered code before clicking on it using firefly. (oh yea, this gridview is also inside of an updatePanel) (In the below I replaced actual data with xxxx)

For each rown in my table has a field called sizes which has data that looks like this "blue; red; yellow; green", I need to render a dropdownlist in the ItemTemplate with these values, I tried placing a PlaceHolder but I don't know how to populate it. I have tried to populate it OnItemDataBound and OnUnload but neither seem to work.

What is the cleanest way to display a web page inside another web page. Currently I am using an I-Frame. But are there any current controls in ASP.NET to do this efficiently?
