The problem that I'm having is one that I'm fearing is a design problem, not a coding problem, but I'll ask the question anyway. I have an ASP.NET 2.0 web application that loads two different user controls dynamically based on a value from a database. Inside each of these user controls is basically a FormView control and a SqlDataSourc...
I'm trying to understand what this method means as I'm reading this and have wondered what uses this may have. I don't quite understand the example given. Can anyone give another explanation of it. Examples would help. Thanks ...
Ok guys and gals, here is my problem: I've built a custom control that uses a textbox to present data to the user. When the user interacts with the control the value of that textbox is altered with client side javascript. I also have a button on my page. When the user clicks the button I want to take the value from the custom control...
I need to generate buttons initially based on quite a processor and disk intensive search. Each button will represent a selection and trigger a postback. My issue is that the postback does not trigger the command b_Command. I guess because the original buttons have not been re-created. I cannot affort to execute the original search i...
In my ASP.NET 1.1 application, I am compressing and replacing the hidden Viewstate variable with an alternate compressed value, stored in a hidden field called __VSTATE. This works well but on a few occasions, submitting a page causes the common "potentially dangerous Request.Form value ..." error. I examined the __VSTATE value and noth...
On an ASP.NET page, I have a GridView populated with the results of a LINQ query. I'm setting the DataSource in code, then calling DataBind on it. In the GridView's RowDataBound event, I'm selectively hiding links in some GridView fields based on the query results. (For instance, I hide the "Show Parent" link of the row in question ha...
As the title suggests, I am having trouble maintaining my code on postback. I have a bunch of jQuery code in the Head section and this works fine until a postback occurs after which it ceases to function! How can I fix this? Does the head not get read on postback, and is there a way in which I can force this to happen? JavaScript is:...
Any 'Page.PreviousPage' call causes the client page render to stop, i know its only the client as i can pull out the results of methods even after the 'page.PreviousPage' line of execution from the server(using mbox[running it local]) -using 'Server.Transfer' on a button - with the target's PostBackUrl in the button setts -and 'Previou...
I have tried, 'PreviousPage', 'PreviousPage.IsCrossPagePostBack' 'Page.previousPage', page.title It causes the client to stop rendering the page after this line. simple example protected void Page_Load(object sender, EventArgs e) { response.write("I can see this"); string test = PreviousPage.IsCrossPagePostBack.toString(); //Any page ...
(Scroll down to bottom of post to find solution.) Got a asp.net page which contains a Datalist. Inside this datalist, there is a template containing a dropdownlist and each time the datalist is filled with an item, a ItemCreatedCommand is called. The itemCreatedCommand is responsible for databinding the dropdownlist. I think the prob...
Hello, I am trying to build a server control that, depending on a "QuestionTypeId" display either a text box, date picker or Yes-No radio buttons. I have my control displaying how I want it to, but when the submit button is pressed on the form, the text box, date picker or radio buttons that were generated in the RenderContents method...
Hi, I need to determine in the page is loading in a partial rendering mode (when posting back from within an UpdatePanel). Any suggestions? ...
This problem has been solved thanks to your suggestions. See the bottom for details. Thanks very much for your help! Our ASP.NET website is accessed from several specific and highly secure international locations. It has been operating fine, but we have added another client location which is exhibiting very strange behaviour. In partic...
I have a GridView control on my page that I have defined a number of BoundFields for. Each row of the databound GridView has a CommandField (Select), for which I want to send the PostBack to a new page. Of course I could easily send the NewSelectedIndex in a QueryString, but I'd rather keep that information hidden from the user. Sugge...
We are trying to decide how to handle object persistence accross postbacks, to avoid getting the data from the database in every request, and I'm leaning towards using Session (it's an intranet application, there won't be thousands of users), but this is due to the fact that I suspect that only the reference to the real object is stored ...
I am trying to make a small, data-driven widget that is populated with data from a database on the fly. I can load it initially just fine, but when the index of an ASP DropDownMenu is changed, the widget returns a 404. This could be a symptom of how I am using the Javascript, or how I am using the ASP. I honestly don't know for sure. ...
If you visit this page in Internet explorer, and choose a value from the "Current Media Releases" dropdown on the top right, eventually IE will try to redirect you to an ugly url containing this string: __EVENTTARGET=selArchives&__EVENTARGUMENT=&__LASTFOCUS=&__VIEWSTATE= The page should only be updating the selArchives Query string val...
The ASP.NET ViewState feature can sometimes be a double edged sword. I rely on it on most of my projects and it speeds up development considerably. My problem is that sometimes users will try to refresh a page which will cause the viewstate to be lost, other times the user might want to bookmark a page but when the get back the viewstat...
Hi all, I've got some trouble with JQuery script on my Asp.net page. During first load it works well, after postback it does not. Initiali I thought that it is because script is not load again, but alert told me that script runs as I use function pageLoad() instead of $(document).ready(function(). In script I just read value from one ...
Could I get some confirmations from the community that I'm not going mad, and that the life cycle of a page during post back is in deed in a different order to when the page is initally requested. If this is the case pointers towards references/articles outlining the order would be greatly appreciated. (A postback equivalent of the pag...
