Web Forms :: How To Avoid The Refresh In MasterPage In ContentPage
Feb 13, 2010
I have a masterpage with a timer that shows server time and refreshes every second, on the content page I have a chat program with ajax, refreshes every to second to get the last messages entered.
I have a Html TextBox and a hidden Submit Button, when user write a text, and hit the enter, I check to see if this is the enter key and then submit the message,it is working perfectly in IE, but in FireFox and Opera it show the same message twice. I think the problem is the Timer, is there any way to avoid the MasterPage timer in this particular content page?
We have a master page file in which we have a MenuControl. We are displaying some menus according to users credentials. We are handling MenuItemDataBound event inside master page for adding & removing menus.
There is user edit page{ContentPage} on which user may edit his own credentials. After saving the edited data {users credentials} by ASP.Net Button control, the MasterPage's MenuItemDataBound event doesn't fire (in case of refresh it is firing but in case of post back it is not firing).
We need to recreate/refresh MenuItems for master pages after saving the user and add/remove any nodes from Menus.
I am trying to get value of a variable"offset" code behind of content page which is set from default.aspx through onload event from master page.But it gives null value every time. Here is my code.
how to set the body class of a ContentPage when using master pages?
I want to set the body class so that certain elements of my page are styles differently from each other. e.g. Navigation links to so which is the current page.
From a content page i am assigning a css class to one of the list item.
HtmlGenericControl home = (HtmlGenericControl)this.Page.Master.FindControl("mainMenu").FindControl("mainManage") as HtmlGenericControl; string cssToApply = "current"; if (null != home) { if (home.Attributes.ContainsKey("class")) { if (!home.Attributes["class"].Contains(cssToApply)) { home.Attributes["class"] += " " + cssToApply; } } else { home.Attributes.Add("class", cssToApply); } } and my css, #header ul li { display:inline; float:left; } #header ul a { -x-system-font:none; color:#FFFFFF; display:block; font-family:Trebuchet MS,Arial,sans-serif; font-size:1.1em; font-style:normal; font-variant:normal; font-weight:bold; text-transform:uppercase; text-decoration:none; } #header ul a { -moz-border-radius:3px; -webkit-border-radius:0.2em; padding:3px 7px; text-decoration:none; } #header ul a:focus, #header ul a:active, #header ul a:hover { background-color:#829E7E; outline-color:-moz-use-text-color; outline-style:none; outline-width:medium; } #header ul a.home { margin:0 16px 0 17px; } #header ul #current a, #headermenu #current span{ /*currently selected tab*/ background-color: #BCE27F; color:#666666; white-space:nowrap; } #header ul a.manage,#header ul a.enquiry,#header ul a.report { margin:0 14px 0 0; } #home #header ul a.home, #enquiry #header ul a.enquiry, #report #header ul a.report, #manage #header ul a.manage{ -moz-border-radius:3px; -webkit-border-radius:0.2em; background-color:#B9E27F; color:#FFFFFF; }
But i get the error, System.Web.UI.AttributeCollection' does not contain a definition for 'ContainsKey' and no extension method 'ContainsKey' accepting a first argument of type 'System.Web.UI.AttributeCollection' could be found (are you missing a using directive or an assembly reference?
I am using a Masterpage for my upload_photo.aspx which displays the file upload page using colorBox. However, ever since i added (code below) in the Masterpage colorBox doesn't display:
I have a DateTime in my MasterPage.aspx that is outside of UpdatePanel1. There are two Hyperlink controls inside UpadatePanel1 to navigate or to move to the other pages. Full code of MasterPage.aspx is below.
[Code]....
If the user clicks Hyperlink to navigate or move to the other page, the DateTime will change. It means that my MasterPage.aspx render the whole page when the user clicks Hyperlink. I do not want this behavior. I want my MasterPage.aspx only render the ContentPage and the Hyperlink inside UpadtePanel1. Controls outside UpadtePanel1 like DateTime should not be rendered again. Please advise the code to achieve my example goal.

I have some asp.net pages that read and write cookie values. During the life cycle of a page it may update the cookie value and then need to read it again further in the code. What I've found is that it's not getting the latest value of the cookie until a page refresh. Is there a way around this? Here's the code I'm using to set and get the values.
public static string GetValue(SessionKey sessionKey) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix]; if (cookie == null) return string.Empty; return cookie[sessionKey.SessionKeyName] ?? string.Empty; } public static void SetValue(SessionKey sessionKey, string sessionValue) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix]; if (cookie == null) cookie = new HttpCookie(cookiePrefix); cookie.Values[sessionKey.SessionKeyName] = sessionValue; cookie.Expires = DateTime.Now.AddHours(1); HttpContext.Current.Response.Cookies.Set(cookie); }
I have a page that shows statistics for users, this cannot be cached because each user has different statistics and there are many thus the real time query must be made.

public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) if (!IsPostBack) // If page loads for first time Session["update"] = Server.UrlEncode(System.DateTime.Now.ToString()); // Assign the Session["update"] with unique value [code]...

is it possible to refresh the contentplaceholder of a masterpage only with ajax? I have a masterpage witch populates a treeview and a menu from a database. The treeview has links to created contentpages but when i click the node the whole page refreshes.
I have an app that uses masterpages. On the masterPages I have a TreeView. I would like to only refresh the ContentPlaceHolder & not the Entire masterPage when a link is clicked on the treeView.
I have placed the contentplaceholder in an Updatepanel. I would like to if possible avoid including the menu in the update panel.
For example, I have master page MyMasterPage.aspx and content page MyDefault.aspx. I have many UpdatePanels at MyMaterPage.aspx, and also I have many UpdatePanels at MyDefault.aspx.
[code]....

I am looking forward an example code for JavaScript functionClickMenu(this).
