Web Forms :: How To Get Gridview In Master Page Which Is Placed In ContentPlaceHolder
Jul 31, 2012
Looking to have a export button in master page. Gridview is placed inside panel, so I couldn't get the gridview to export to excel. I have gridview's wherein I can able to export to excel that are directly placed in maincontent (Content PlaceHolder). The problem is if gridview is placed inside panel I couldn't export.
protected void LinkButtonExport_Click(object sender, EventArgs e) {
foreach (Control ctr in MainContent.Controls) {
GridView gv = ctr as GridView; if (gv != null)
{ ExportUtil.Export("Test.xls", gv);
} else {
LinkButtonExport.Enabled = false; }
}}

As the first step, I designed a Master Page for my website. Everything seems to be in order. My master page has a table say "Mytable" with 2 rows.
In the first row, I've put up a banner for the website.
In the second row, I want to place the ContentPlaceHolder.
The thing is that I can't make the ContentPlaceHolder to occupy the whole cell. I tried finding the solution through search engines and could not find out a solution.
In my web page, I want to create a table by Javascript. I mean that I want to make this table to occupy the second row of "Mytable". There is still some gaps left at the top and bottom of the ContentPlaceHolder.

I have two master pages in my project, one for web views and another for emails. In the web master page is a placeholder to put page specific JavaScript, if a page is using this and I try to programmatically change the masterpage to send as an email the server falls over as it can't find the placeholder.
Is there a way to change the behaviour so that if a placeholder can't be found it just doesn't include that bit? I'm thinking maybe on my page base class looping over a collection of placeholders and content tags and removing the ones that don't match up, but I'm not sure if there's a good point in the page lifecycle to do this.
I'm using MVC not WebForms if this makes a difference.

I have a master page which has several ContentPlaceHolders. Not all of them are used by the current content page all the time. During page rendering the master page needs to set a property when a ContentPlaceHolder wasn't used by the current content page. Meaning a ContentPlaceHolder might not be referenced by the content page.What's the best way for the master page to iterate through its ContentPlaceHolders and find out which ones haven't been used by the current content page? Looking for a solution that does not involve any communication from content page to master page.

Apologies for the terribly newb question. We're currently implementing Google Web Optimizer in our ASP.NET Web Application and some of the code is supposed to go in very specific places on certain pages. For example, for the "Control Page" Google has some Javascript that sits outside of the <html> tags.
I know I probably don't need to place the code exactly where Google recommends, but we've been getting some goofy results lately, and I really wanted to make it as watertight as possible to ensure it's not just bad implementation. We have a lot of files in our project that reference the site.master, but only one needs to have some Javascript placed outside the <html> tag. This, in theory, seems simple enough, my question is this: Do I need to put a ContentPlaceHolder in every file that references the site.master? (Even the tens that aren't passing any code to the site.master?) That's not something I feel like doing for many different reasons (altering tens of files). If that's the case, and I do need to add empty ContectPlaceHolders to every page, is there some other way around things without having to piece together a unique file just to put some Javascript outside of the <html> tag?

I have a page which is linked with masterpage.
In my masterpage i have already defined metakeywords and description. But for one of my page i would like to define metakeywords and description which will be for that page only.
The metakeywords and desciption defined in master page is for the website.
Where and How to define metakeywords and desciption for any page which doesn't have <head> tag as it is linked with masterpage.
This is my About.aspx page code :
<%@ Page Language="C#" MasterPageFile="~/MasterPages/OneColumn.master" AutoEventWireup="true"
Inherits="Web.AboutPage" CodeBehind="About.aspx.cs"
%>
<%@ Register TagPrefix="MyTag" TagName="Topic" Src="~/Modules/Topic.ascx" %>
<asp:Content ID="Content1" ContentPlaceHolderID="cph1" runat="Server">
<nopCommerce:Topic ID="topicAbout" runat="server" TopicName="About">
</nopCommerce:Topic>
</asp:Content>

My Project is a normal web site, not a Web Project, and I am using VS 2005.
I am trying to define common Master Page Type in app_code which has an area to display error messages and the like. Very simple.
I added the following in app_code:
[Code]....
Also, I added the following in Master Page Source Declaration:
[Code]....
Also, I added the controls tblrowErrMsg and lblErrMsg as server controls to the Master Page.
Why I am doing this ?
This will allow me to display error messages from nearly any where inside the code in code-behined, app_code, and other core Class Projects (DLL).

I'm incorporating some parts of an old asp application into a newly written mvc app. In most places I've separated out the data access and business logic into the model, and written new view's and viewmodels on the mvc side, although what I ended up with was not perfect, it works reasonably well.There's one area that's probably a bit too much work to do that. It uses an asp treeview and custom controls, and has lot's of code that just isn't partitioned very well. It's one of those 'well I wouldn't start here' situations, but unfortunately it's the code I have. As an application in it's own right it works well and has done for the past 5 years or so. Although it does want re-writing, that's probably more work than I wanted to do right now if I can get away with it.
The asp pages decend from a custom asp page, which itself decends from asppage and contains a custom DAL. What I'd really like to do, is 'paste' the page produced by this legacy asp page into the 'main' contentplaceholder area on an mvc form. I know I can incorporate standard asp pages into an mvc application, but that isn't what I'm trying to do as I want to use the master page from the mvc application.

I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?

I have following environment:
masterpage with a contentPlacholder multiple pages which use this masterpage and implement a base-class (fooPage) fooPage has a certain property (fooProperty)
[Code]....
Obviously this is not going to work - but how can I achieve this?
I know the alternative: call a method from the masterPage in the contentPage with fooProperty as a parameter - but i would like to rather have a pull-system in this case...

I've been working with ListView for a long time, but I haven't been using it's built-in events so far. Now I was trying and was stuck. Until I moved both LinqDataSource and ListView to another page, without a master page.
Then it worked. Same happened with GridView as well.
I do not use Update Panel. Just master page. And if I use manual methods for edit, insert, delete then it doesn't fire OnItemCommand.
Is there a known uncompatibility with databound controls and master pages? Because I couldn't find anything about it on Google.

I'm trying to dynamically change the look of my main master page depending on what nested master page that the current content page is using .
So for example.
Main master page = main.master
My nested page = nested.master (uses main.master)
content page = content.aspx (uses nested.master)
So in the Page_Load event of main.master I want to add a switch statement that will check to see what nested master page is currently being used by content.aspx, or whatever content page is loaded.
So far I have got
protected void Page_Load(object sender, EventArgs e)
{
string nMaster = //This is the line of code that I am looking for.
switch(master)
{
case "nested.master":
//all my logic here.
break;
}
}

I have a master page containing a tree and 3 dropdown lists. I am populating a context menu on right click of each node, and when clicked on any item of the context menu, it navigates to required pages.
My problem is after navigating to the required page, the selected values from the drop down lists and the selected node from the tree are getting cleared.
I can set the selected values for the dropdown lists by making some properties in master page.
But how do i maintain the selected node?
In my content page, i have got the valuepath of the right clicked node.
Or is there any other way than setting the properties in master page?
