AJAX :: GeneratedImage Control Imaagesnot Displaying?
Jan 7, 2011
I am trying to use the GeneratedImage Control to display images. The images are retrieved from a data base and are stored im SQL Image format. Previously I displayed the images from an ASP.NET page serving the pictures and of course this is very slow. I am switching to the GeneratedImage Control to take advantage of the images transform and cache features. A snipit of my code is below:GeneratedImage Control :
I've got an issue where I'm unable to view Ajax controls within the Visual Studio toolbox section What makes this issue even more bizzare is that I'm able to view the controls of the .dll (AjaxControlToolkit.dll) in a test website. I can see Visual Studio iterate through the controls and add them to the tab in one project and absolutely nothing in the other. I've already checked to see if another tab has my controls and done multiple Toolbox resets. Obviously, I need consistency with this and for me to be able to easily add controls to my target website...Does anyone know why one VS2008 project displays controls correctly in one place but not in another project?
had an tab control with more than 10 tabs, each tabs im using button but while button click event the Updateprogress not displaying, may i know the reason and how to solve it?
I have a web form with a modalpopupextender and a listView control that opens for editing and adding records. One of the columns on the listview is a linkbutton that makes a serve side call to show the modaldialpopupextender. At first, when clicking on the linkbutton in the listview the modalpopup displays over the listview, the page fades (via a CSS class) and it works great. When I open and close the listview for editing or change pages on the listview, and then try to show the modalpopup via the linkbutton, the modalpopup displays under the listview and the fading does not work properly. I am not too sure if this is a postback/javascript issue or maybe CSS?
I have an interesting problem when using partial page update in asp.net with scriptmanager and a update panel.
My scenario looks like this: I'm using the tab control from the ajax toolkit. I also implemented this control using lazy loading, so that when the page is loaded only the current tab gets loaded all the other tabs don't get rendered, because Im using an UpdatePanel (on a .ascx control) on each of these tabs and when a tab gets selected the updatepanel makes a async postback to load the content for a selected tab.
On one of my tabs Im using a combobox control from obout.com, and it doesn't work. Now I know why it doesn't work. It doesn't work because the control is shown via a partial page refresh, but to correctly display the control it has to do some "magic" that is - register some .css and .js includes on the page (in the head I guess)....but because I load this control via async page refresh.
I'm using the AutoCompleteExtender control with a textbox. The control functions the way I want it to but I have one issue with it. When the page first loads I type something in the textbox and I get a list of suggestions from my database. When the list is quite big the vertical scroll bar appears on the right side of the browser window and the textbox is repositioned to the center of the page (I want the textbox to be centrally positioned and I'm using <center> tags). Unfortunately the AutoCompleteExtender list doesn't reposition and is misaligned. The same thing happens when the browser window is resized.
I've played around with CSS and OnClientShown and haven't managed to fix this. I'm currently using IE8.
I have a flash on my page and I need to popup an ajax window, I use ModalPopupExtender. The problem is that ajax popup window always shows behind the flash in Internet explorer and Google Chrome. In firefox there are no such problem.
I have an ajax tabcontainer on a master page that has a user control inside one of its tabs.The user control is just a gridview that gets a list populated from a DB table.The strange thing is that the gridview is displaying in VS, but when I build the site the tab is empty; no error message just nothing.Below is the code for the tab in my master page:
I want to use button instead of filuploader control, so I tried the html this way and i got it right. But my challenge now is how to code it on code behind
Situation: I have a drop down list which I need to pass on to a webservice on button click. I am using Sys.Net.WebServiceProxy.Invoke to make webservice call.
Everything is happening inside a usercontrol which loads on runtime using dynamicpopulate extender.
I get following error:
Sys.InvalidOperationException: Cannot serialize object with cyclic reference within child properties.
Situation: Usercontrol also has a listview which is bound to dataset. However on calling listview.DataBind() in side the webservice method.
I get following error:
The ListView control 'ProductsListView' does not have a naming container. Ensure that the control is added to the page before calling DataBind.
There is no problem when call to service method is parameter less and listitem is not bound.
I have two InlineEditBox.NET controls in a template field inside a GridView. When displayed in the GridView, the first row is OK, but starting with the second row, the controls are automatically displayed in edit mode when the page loads, and I can't figure out why.
In my scenerio, i've a dropdownlistbox by which i want to filter, a textbox for the text to filter and two textbox for specifying from and to date.
A gridview control for displaying the filtered data and a sqldatasource control and a commandbutton called search.
The following code is used to filter the data in database and it works properly. But when i click on edit in gridview, the gridview displays no records and again when i click on search button the data is displayed on the gridview displayed with the selected row in editmode.
I'm attempting to build a page that displays the same set of information of different "items" in a grid or table. It's akin to a shopping page that displays products in for e.g. a 4 by 3 table.
I came across datagrid and gridview but they display grouped information according to columns and each row representing one item only.
Is there a control that displays data in a very basic grid format instead of tabular form, preferably with built in pagination abilities?
I have a RadTabStrip that just refuses to show on page load or reload. WHen My page load, the control is supposed to be loaded in the back with data and then displayed on the page. That isn't happening. The process runs through as expected in the server side but the rabtab is not displayed at all. Below is my code. I did notice that every so often,when I click F5 the tabs display, only the only way I get them to refresh is to refresh the Page using F6 again.
We've just upgraded to IE8 and for some reason only a portion of an .aspx page, created using VS05, is displayed. All of my Labels and TextBoxes are in an UpdatePanel. If the site is run locally on my PC, everything is fine. Has anyone else experienced this and is there a fix?
I looked into a nice way to display tooltips dynamically and I found OverLibWrapper, which was exactly what I needed.
I have all the tooltip data stored in a custom configuration section, the tooltips are bound to their respective controls during Page_Load.
I did a quick test and worked fine. The problem came up when I realized that OverLibWrapper didn't work on masterpages. Our website has uses quite a few masterpages, so taking them out isn't an option.
I was wondering if there's anything like OverLibWrapper that I could use.
EDIT:
What I'm looking for is a control to display good-looking tooltips on mouseover preferably instantly like overlib (nothing fancy because I'm just displaying raw text) in a dynamic way, because the tooltip property in ASP.NET is not very pretty and takes a while to appear. For example let's say I have a collection of Messages:
class Message { string ctrlid, msgtodisplay; }
And when the page is loaded:
TooltipManager manager; foreach(var m in messages) { Tooltip tltp=new Tooltip; m.ControlID=m.ctrlid; m.Message=m.msgtodisplay; manager.AddTooltip(tltp); }
So basically something that offers the functionality of Tooltip and TooltipManager.
I'm trying to include a user control in an aspx page, it works fine, but my control does position itself where I want it and always appears at the very top of the page. Could it have something to do with the masterpage? I've tried registering the user control in the master page, but I don't know how to reference it in the content page.
In my Default.aspx page I register my usercontrol at the top:
When designing an ASP.NET user control my standard way for creating say a details view would be to create a property of the desired type on my page and would set the property in the page load based on the supplied query parameter. I feel I'm probably doing more work then necessary. If I could encase my view inside a container then I could merely have it databound and thus make everything declarative.My question is what would be the lightweight container/controls that would be appropriate for databinding a single object?As a second question, how can I handle invalid query strings with this method?
i have designed a usercontrol (ascx) and it was ran on local machine, i have uploaded that into the server after that its not displaying on the aspx pages, i have uploaded all the images, scripts, aspx, ascx, dll but i dont know why its not displaying?
