Web Forms :: Different User Controls With Just One Place Holder?

Jan 21, 2010

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.

Just 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.

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.

Web Forms :: Hide Hyperlinks In Master Content Place Holder?

May 4, 2010

im 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.

Web Forms :: How To Write The Content Directly To The Place Holder On The Master Page

Feb 15, 2010

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.

Movie File Place Holder?

May 8, 2012

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.

Web Forms :: Reset Field Code Not Working When Using A Form Inside A Content Place Holder

Mar 10, 2010

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.

Visual Studio :: How To Work Only On Content Place Holder In VS2010 Without Seeing Master Pages

Jan 25, 2011

I 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.

AJAX :: Can Change The Content Of The Content Place Holder To A New Page With Asynchronous Postback

Jan 4, 2010

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.

C# - Is It Possible To Read The Content Of A Content Place Holder From The Masterpage

Oct 25, 2010

We 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.

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?

Setting A WebControls TabIndex Based On The ControlId Of Another Control?

Apr 1, 2010

I 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"/>
