View 10 RepliesI want to handle asynchronous post back timeout error (Sys.WebForms.PageRequestManagerTimeoutException) on server side.
I use AsyncPostBackError event of ScriptManager class for other errors (exceptions) during asynchronous post back and it works fine. There is a response redirect to generic error page in this event handler.
Unfortunately for PageRequestManagerTimeoutException this event is not fired.
So how can I handle this error on server side?
scriptMgr.AsyncPostBackTimeout = 180;scriptMgr.AsyncPostBackError += new EventHandler<AsyncPostBackErrorEventArgs>(scriptMgr_AsyncPostBackError);...private void scriptMgr_AsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e){Response.Redirect("~/System/GenericError.aspx");}
I am trying to render the Button control @ serverside with PostBackUrl properties to set to another page ""~/page1.aspx". When I click on that button , it still postback to same page , does not postback to "page1.aspx" . I am trying to implement crosspage postback. I don't know button information and postbackurl info at design time. I Only know button and PostbackUrl info @ runtime.Code I am using
protected void Page_Load(object sender, EventArgs e)
{ div1.InnerHtml = GetRenderControl(); }
public
string GetRenderControl()
{ Button buttonAdd = new Button();

I have a ListView that contains a large collection of rows with textboxes that users can optionally fill out. These textboxes are not databound. When the user clicks "next" i need to iterate over the rows and determine which fields the user has filled out, and then update a sort of "cart" with the data and move to a confirmation page ("you have selected a, g, v, zz, is this correct?" sort of thing).
I can think of two ways to deal with this. The first is, server side, to walk the items in the listview, get the control ID's, save this data to a list, then save it to a database cart table for the next screen to read.I can use jquery to collect all the values client side, then pass it back to the form in a hidden field and use something like Newton.Json to get the data into a similar list.What are the tradoffs of these two approaches?
I'm using a ModalPopupExtender in my website, to show "accept/cancel" messages, and catch the user selection at the server side. I put two buttons (ok/cancel) at the panel that will be shown as a modal popup, add them a server side event handler, but it does not fire.

I need the user to be able to upload multiple files to my server, thus I am using the SWFUpload utility. SWFUpload sends the files one by one, and I need to store them all in the same temporary directory. My ASP.NET handler recieves the files one by one and I can store the file appropriately.
My problem is: How do I know which files belong to the same upload? Rephrased, how do I connect the files in my handler?
am looking to save/update my webform through a server side button control. On button click, I'd like to disable the save/update button and show a progress bar of the save through a modal or some other trick disabling the form being saved.How can I implement this

View 7 RepliesI have a button on a webpage that has the following added programmatically to its "Attributes" property.
btnDeleteNode.Attributes.Add("onclick", "if(confirm('delete this node?')){}else{return false}");
This works fine but now I need to check to see if the user has selected a node in a tree before asking if they want to delete it. If a node isn't selected I need to tell the user to select one. My question is, can I do this using the above method (I don't know java script) or should I use a different approach ?
In the logout link button click event I have cleared the session variables.I am checking these session variables for null values at each page's load event.If it has the null value redirecting them to the login page.But the problem is whenever I click the browser back button,the page_load event won't get called.For that I have cleared the the browser cache history.
View 2 Replieshave a data access layer, a business logic layer and a presentation layer (ie. the pages themselves). handle the OnPreInit event and populate collections required for the page. All the data comes from an SQL server database and I do not use caching.I handle a button click event to grab values from a form and insert a new object into the database. The problem is that by the time I handle the click event, the collections have already been populated, so the new item which has been inserted into the database has not been retrieved.What is the accepted solution to this?I could insert the new object directly into the collection and re-bind the GridView, but the SQL query selects only a set of objects and the new object could fall outside of this set.

View 5 RepliesI've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?

I have ASPX page named ArtifactReporting.aspx where I have 3 linkbuttons. For each button I have 3 different UserControls to be loaded dynamically. So I have written for each click
UserControl uc = (UserControl)this.LoadControl("<ASCX page name>");
divArtifact.Controls.Add(uc);
Now in one of the ASCX page I have a server side button. When I click on the button, the content of the ascx is going off, which is correct, because the page post back is happening and in Page_Load I have not written anything that will load the ASCX page.
how to go about this? I need if I load an usercontrol dynamically, I should be let the users carryout operation that usercontrol.
For the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether.
Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls.
If I am understanding the ASP.NET documentation correctly, then I can find only two options:
Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same.Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control?
Is there a way to do so using a single validator control with no code behind?
