C# - Refresh A Webpage Automatically From Within A Loop?
Feb 28, 2010
I have a loop that runs through a variety of websites and I'd like to put some kind of a postback in the loop so that each time through a textbox would refresh with the url that is currently being considered. I don't know AJAX yet so I'd like to redo the webpage. I am currently using a session variable to hold data for display between page loads. I have tried
I need to loop through all the controls in my asp.net webpage and do something to the control. In one instance I'm making a giant string out of the page and emailing it to myself, and in another case I'm saving everything to a cookie. The problem is masterpages and items with collections of controls inside them. I want to be able to pass in a Page to the method, then have that method be generic enough to loop through all controls in the inner-most content page and work with them. I've tried doing this with recursion, but my recursion is incomplete. I want to pass a Page object into a method, and have that method loop through all controls in the innermost content page. How can I achieve this?
private static String controlToString(Control control) { StringBuilder result = new StringBuilder(); String controlID = String.Empty; Type type = null; foreach (Control c in control.Controls) { try { controlID = c.ID.ToString(); if (c is IEditableTextControl) { result.Append(controlID + ": " + ((IEditableTextControl)c).Text); result.Append("<br />"); } else if (c is ICheckBoxControl) { result.Append(controlID + ": " + ((ICheckBoxControl)c).Checked); result.Append("<br />"); } else if (c is ListControl) { result.Append(controlID + ": " + ((ListControl)c).SelectedValue); result.Append("<br />"); } else if (c.HasControls()) { result.Append(controlToString(c)); } //result.Append("<br />"); } catch (Exception e) { } } return result.ToString(); } Without Try/catch Object reference not set to an instance of an object. On line controlID = .....

I'm using Visual Web Developer 2008 Express Edition and I'm new to it. I want to refresh or reload a webpage everytime after the event was handled. To expound more, if I have a click eventhandler using the command button which updates a records, I want to refresh or reload the page right after the update event so that the records in my gridview control will be updated as well right after you click the update button. I need the code for that to refresh or reload the page using either c# or vb.net.
In one of my website, i required to implement automatic refresh of webpage after 15 minute.
For this to achive i have write following line of code <meta http-equiv="refresh" content="60;url=" />
But i am facing one problem that after this duration of 15minute page will refresh as a new page load.
At my page i have used combo box having city list, there is a case when i select an item from this list at index 3. After that i just make page idle and after 15 minute page is refresh with the script i write for auto post back (mentioned above). But the problem is that due to this page is reload as a new page and code inside (!PostBack) execute which refill combobox and reset at index 1. My basic requirement is that whenever user reaches that page and makes it idle for longer time, session should not expire and hence i am writing above script so that session would be live.
