Instead of placing this method in the code-behind of every page, I want to put it in a single class and call it accordingly. I thought of using a static class but do not know how to reference the MasterPage.Can I use a static class? or do I place the method in the code-behind of one page and call Object.Method from the other pages?
I am attempting to access a textbox control on a master page from a code behind base class but having problems. I have 3 levels of master pages. m1.master is the master page for m2.master which is the master page for m3.master.m3.master has a textbox as shown below
I'm trying to write a way of setting the css class on the body tag in a master page from the content form page through a page directive variable. Everything seems like it should work here, however when I use my BodyCssClass variable, the page content isn't generated, just the master page content. Also, if instead of using the page directive variable, I just put <% BodyCssClass = "mybodyclass"; %> in default.aspx, that works.
[BasePage.cs] using System; using System.Data; using System.Configuration;
I have a base class called BasePage, and a master page called SiteMaster. All my content pages inherit BasePage using BasePage instead of System.Web.UI.Page. Now, I need to access some functions in BasePage from my master page SiteMaster, let's say, the function is called "DisplayClientName()". How can I do it? Searched the Web, have found tons of similar questions but not solid solutions.
I want to add a class and initialize a JS funcion behind my nested masterpage which is being dervised from an other master page. But when I add the following code in the PageLoade event in the code behined of my derived page then it give the folowing error
System.NullReferenceException: Object reference not set to an instance of an object.
I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the heme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" />
Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this:
I have a div on my master page and I want to use it for showing page errors. I have an error display class and it works fine. My problem is that in some instances, the error gets displayed even before the tag resulting in (non)-display of the message. This is mostly with code that has response.redirect.
I want to counter this by having the error shown on a div within my master page.
How can I access <div id="errorSegment" runat="server">?
I want to search my asp.net pages and user controls to see which master page and base class they use. I mention search because we are re-factoring a large project and we need to track progress on the code conversion. I know I can pull this information individually but I need a automated and repeatable procedure.
Currently I'm doing common functionality required throughout my site inside of my masterpage. What I want to do is move this functionality to a BaseClass so All my pages inherit from the Base Class. However, I'm not sure how to set this up interms of c# code with regards to Using a Base Class and then having a masterpage applied to my aspx pages that i create.
