Web Forms :: Display Vb Code Within Contentplaceholder?
Aug 13, 2010
is there a way you can make the results of vb code held on an aspx.vb page display within a contentplaceholder on a master page? I've included my code below, there is a textbox and 2 buttons on the aspx page but the code runs in the aspx.vb page. The code basically works, but when run it prints the resulting table above the placeholder rather than within.
Imports System.Data.SqlClient
Imports System.Data
Partial Class Software_pc_SearchPC
Inherits System.Web.UI.Page

I'm about to create a masterpage that contains a search field, the result from the search should be placed inside a contentplaceholder, but how do I build that? I added the search form to the masterpage (not inside a contentplaceholder), and then I added the eventhandler for the button that trigger the search. Now lest say I want to display the result in the contentplaceholder, how would I do that?

I'm using CRv9 and want to make use of Google Charts API for generating QR code on fly (in asp .net) and display it in the Crystal Report in a PDF format.I have spent the whole day looking for solution with no luck. The way we output the report is we use .rpt file, feed it with data and use Response.OutputStream to feed to browser. No CrystalReportViewer control hence CSS solution is not an option.
Now, I got as far as added an OLE Object from file with Link, which I would be overwriting every time the new QR code is generated. I apreciate that CR requires it to be a bitmap, so I was planning to download and convert the google's generated PNG file to BMP, that's not an issue. The problem is that Image in the report does not update after I replace the file. Meaning, it displays the original image, which was added as an OLE Object.
If I open this report in CR designer, the image gets refresh/updated and I'd have to save changes to the report to see this new image next time I generate a PDF file.The question is really how to achieve a dynamic image in Crystal Reports 9? Remember, Picture object did not have a Graphic Location property until vXI, so I cannot use that.
Manipulations with DataSets is not an option either as we're not giving report a datasource, instead we just map the fields with FormulaFieldDefinitions.

Basically I was wondering if there is a method of binding a datasource to a contentplaceholder, I want to display data within a contentplaceholder from a database, however as I can't insert a control into a contentplaceholder, I have nothing to bind/display the data. The information within the database includes html for presentation, therefore I just need to get it out. Also the master page will only be supplying one page with data, so doing this within the master page would also be a solution.

I have a panel which is filled with textboxes and labels. I have appropriately sized this layout panel to fit in the contentplaceholder. Unfortunately this layout panel does not stick properly in this contentplaceholder. It moves out of the contentplaceholder when the window is resized. Is there a way for the panel to stick to the contentplaceholder?
If a text is entered in this contentplaceholder, it will move along with the contentplaceholder. But I want objects (textbox, labels, panel etc) to stick with the contentplaceholder and move along with it when the window is resized. What is the way for this?

I am working with an individual who is redeveloping content for my site. He however only does HTML and PHP. He dev'd the layout that I created with a master page with .cs. I have a placeholder on the master page. He is going to continue to develop content for my site that he will be updating. Since he works with HTML I was wondering if there is a way to allow him to edit an HTML file regularly but place the contents of that file within the asp:contentplaceholder tags on each individual page.

I have posted below the code to a very simple log-in page, but can't work out why, when viewed in a browser (Chrome, - I haven't tried others), it appears way down the page in the ContentPlaceHolder and not at the top. Also, how would I make such 'functions' as log-in boxes like this one appear centred on the ContentPlaceHolder as opposed to formatted to the left?
If anyone could indicate where in this code it states to align the log-in function box to the left
and half way down the page (not align to the MasterPage header
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">

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>

Then, in the codebehind I have this code:

This works fine when I display the page. However, when I click the language link which causes a postback the content block does not get added to the placeholder, so I get a null reference because those two panels don't exist. I've been pulling my hair out over this for a few hours now and I can't figure it out. In case it helps, here is my InitializeCutlture method:

I am working with ASP.NET 2.0 and Visual Studio 2005. I am using masterpages and have a form with 15 textboxes located in the ContentPlaceHolder of one particular form. I need to loop through the textboxes and process the input for each one. I'm programming in VB.NET and have not been able to figure out how to code the looping. All textboxes are located within 1 <div> tag.

I have dynamically built my treeview by reading hierarchical data from database, I have divided my MasterPage like so:
<table width="100%">
<tr>
<td style="width:20%">
<asp:TreeView ID="root" Visible="true" runat="server" RootNodeStyle-ForeColor="BlueViolet">
</asp:TreeView>
</td>
<td>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"></asp:ContentPlaceHolder>
</td>
</tr>
</table>
When I click on one of my treenode, I need to set the node.target to the "ContentPlaceHolder1", ie, keep the tree menu as still and let the content page displayed at the right part of the page. However, the node doesn't seem to recognize the ContentPlaceHolder1.
2. I have tried using <frameset> with 2<frame> pages, this way, the node.target can recognize the frame id, code as below:
<frameset cols="25%, *">
<frame src="menu.aspx" name="Menu"></frame>
<frame src="Main.aspx" name="Content"></frame>
</frameset>
But, I need to check user's login permission, I did it with session("userId") variable and I ran into a problem that the session will only exists on the left frame(menu.aspx), not the content page(Main.aspx). I have tried both methods, but one way or the other, there is some function that I cannot accomplish.

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.

In the master page code behind I added
public ContentPlaceHolder BodyPlaceHolder
{
get { return ContentPlaceHolder1; }
}
and now, in web content form I want to add to this place holder a new ascx control in code behind.
protected void Page_Load(object sender, EventArgs e)
{
if (!User.Identity.IsAuthenticated)
{
LoginRegisterControl lrControl = new LoginRegisterControl();
Master.BodyPlaceHolder.Controls.Add(lrControl);
}
else
{
UserProfile upControl = new UserProfile();
Master.BodyPlaceHolder.Controls.Add(new Button());
}
}
and this doesn't work. If I change this to
Master.BodyPlaceHolder.Controls.Add(new Button());
It works. So the problem is with the ascx user control.
