I have an application which has a default.aspx page. Inside the default.aspx page i have several <asp:placeholders>. I also created several webcontrols.
<asp:PlaceHolder id="headerPlaceHolder" runat="server">
My code:
[Code]....
But when I look at the result, just one RSS instance displayed. How can I add without create two instances of RSS control like this:
[Code]....
i want to create a few textbox dynamically in place holder but when i created and click on btn and use findcontrol to retrive input data that created dynamically storing data in db , i will receive an error like this :
Object reference not set to an instance of an object
I want to have only 1 placeholder on the page and depending on which buttons are pressed, different user controls are dynamically added. To add to the
fun of everything, I need to pass in different values for each user control.
I know that in order to have the values passed into the different user controls and bind to a certain list it needs to happen in the Page_Init inside of the .ascx.cs file - aside from that, I am lost.
how to iterate through all the controls in just my Content place holder ? What I'm looking to do is to Enable/Disable all the controls in my Content place holder (WEbControls as well as HTML Controls).
View 2 RepliesJust getting started on ASP .NET and I have a question. I've created a user control that is show's an image. Using a place holder I add 5 items of that control. The problem is that in the display it shows me the control's vertically and I want it to be shown horizontally. Just to demonstrate what I mean (the numbers are the user controls been added):It shows:
1
2
3
4
5
I wanted to show: 1 2 3 4 5 I've tried a few thing's such as using a table - but the table expands with the place holder so It didn't make a differences.

View 2 Repliesim trying to do the following test:
i have one web page (test) and two masterpages (master_1 & master_2).
the test's masterpage is determined by querystring, so far it's working fine. both master pages have a set on links in content place holder area, but is it possible i can hide the content place holder where my links are, from one of the masterpage when my test page loads, because i don't wish to use the links in the masterpage for my test page. i don't want to delete the links either as i'll need them later on.
I have a master page called SiteMaster.master
The master page has a content place holder (ContentPlaceHolderID="MainContent")
I have a default page (default.aspx) with a VB code behind which pulls some data.
What I'd like to be able to do is write my data to that place holder for example:
<b>theData</b>
This is a simplified example of what I'll be doing but the part I can't figure out is how to write the content directly to the place holder on the master page from the code behind of the default the page.
i put one label in Master Page,
i want to change that name according to the conditions.
i have another page HOme.aspx,in that i enter user name. that name should come in Master page lable for that what should i do.?
I'm putting together a help page for my web app and figured that rather than the usual 'Help' file stuff, I could put a short video help file along with an explanation.
I have a page with around 12 topics, I'd like the user to be able to click a link and it shows a video clip (either .avi or mov file) on the page. It would be cool if the movie placeholder just showed the link to the movie that was clicked rather than a new page each time.
i am using this code to reset all my textboxes and Dropdowmlists after the button is clicked:
void resetField(object myObj)
{
//RadioButton rl;
string temp = myObj.GetType().ToString();
switch (myObj.GetType().ToString())
{
case "System.Web.UI.WebControls.TextBox":
((TextBox)myObj).Text = "";
break;
case "System.Web.UI.WebControls.DropDownList":
((DropDownList)myObj).SelectedValue = "N/A";
break;
default:
break;
}
}
i have tested this code and it works great separately .. the only difference is on my project i have DIV, tables, TABs and ContentPlaceHolder. not sure if this can make this code not working.. i am not getting any error..but nothing is happening.
My master page has 3 content place holders:
1. left side bar
2. middle content area
3. right side bar
So it looks like:
<div id="left"></div>
<div id="content"></div>
<div id="right"></div>
On a particular view page (.aspx) that inherits the master page, I want to now show #3 (right side bar).
So I don't want the to be rendered at all.
i m using a place holder in which i m inserting checkbox list but i m unable to retrive selected values

I have a default page which has a content place holder on it...It defaults to the master.aspx page. Anyroad I attempt to put the loginview there but I can't seem to resize it. Is there something I'm doing wrong? I also put an ajax control in the loggedintemplate and I can't seem to resize that properly either.
View 5 RepliesI am wondering if it's possible to work on Content Place Holder window without seeing master page template?
The second problem i've noticed is that when i try to add a table (1 row, 3 columns) to my content place holder and then try to adjust the width of those columns the whole layout of my page is getting messed up to the point that i have to use ctrl+x to go back to previous stage. The master page was very complicated but i finally got it to work and i don't understand why while i manipulate contentplaceholder the layout of the master page is being affected. (only when adjusting tables)I am new to Visual Studio and was wondering of any known standars in that matter.
I've created 3 buttons, first button is to load the values in textboxes added to placeholder. Then button2 is to extract the data from button 1 and display out. Now the 3rd step, I want to edit the values from the textboxes, after edit, how do I grab and display out the new values in label and textboxes?
Code:
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim x As Integer = 1
Dim message As String

I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.
View 9 RepliesWe would like to use a contentPlaceHolder in our pages to set titles. What we would like to do is have the masterpage check the contentPlaceHolder to see if it has content in it. This way we can set up an e-mailer that will tell us what pages that don't have page titles since we have a fairly large site. We also have nested masterpages.
View 1 RepliesI have managed to place a dropdown control iniside a gridview control. The dropdown does indeed populate in each row... Question: How is it possible for the system to correctly select the text in the dropdown based on the value of the field which is driven from the database? Is it to do with the selectedvalue?
View 7 Replies'm getting the above error on one server (production of course, it's always production). On two other servers and in my local dev server, the exact same code runs fine. I do see the Display property has ThemableAttribute(false) in the documentation, so the fact that it IS working seems to be the anomoly, but how could this be working in 75% of the environments I'm testing in?
View 5 RepliesI have an ASP.NET Webforms site that is regularly having features added.The majority of time a new WebControl is added to the page and I need to increment the TabIndex to all subsequent controls on the page.I'd prefer a more robust solution than choosing an arbitrary gap between the initial assigned tab indexes. Setting the tab indexes using the designer tab order functionality is one option but I'd prefer to stay in the source view.Ideally, if I had, for example, three check boxes I'd like to be able to define the tabindex based off the previous controls tabindex. Then I'd only need to insert the new control and change one existing control.For example, add a new property TabIndexAfterControlId to WebControl:
<asp:CheckBox ID="checkBoxA" runat="server" TabIndex="1"/>
<asp:CheckBox ID="checkBoxB" runat="server" TabIndexAfterControlId="checkBoxA"/>
<asp:CheckBox ID="checkBoxC" runat="server" TabIndexAfterControlId="checkBoxB"/>
I want to place two datalist controls at the same (x,y) position. When the first is visible, second should be invisible.
How would I go about implementing this?
I have a application which uses webparts and 1 control is also a Script Control.So my user controls are derived from System.Web.UI.WebControls.WebParts.WebPart which makes them webpartsI have everything setup and working fine as far as the personalization and webpart goes... every thing displays and works fine.Except that 1 of my control needs to do a bit of work in the OnPreRender event and it turns out that event only gets fired when a user is loged in the application
