View 5 RepliesServer Side Control Hidden - Possible To Read Values Client Side
Jan 30, 2010I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?

View 4 RepliesHow To Get Same Validators Control To Both Client Side And Server Side
May 20, 2010For the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether.
Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls.
If I am understanding the ASP.NET documentation correctly, then I can find only two options:
Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same.Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control?
Is there a way to do so using a single validator control with no code behind?
Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked
Nov 23, 2010I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
Render - Server Control Emitting Server Side Tags?
Feb 19, 2010I'm new to writing custom ASP.NET server controls, and I'm encountering the following issue:
I have a control that inherits from System.Web.UI.HtmlControls.HtmlGenericControl. I override the control's Render method, use the HtmlTextWriter to emit some custom HTML (basically a TD tag with some custom attributes), and then call the case class' Render method.
Using the control:
<dc:Header id="header1" runat="Server" DataColumn="MemberNumber" Width="30%">Member Number</dc:Header >
The problem is that when I view my rendered HTML, the server tag is emitted to the client as well (right after the TD tag):
<dc:Header id="ctl00_ContentPlaceHolder_testData1_testData1_header1">Member Number</dc:Header>
How do I prevent this from happening?

View 2 RepliesDetermine The Client Side Name Of A Server Control?
Feb 4, 2011Let's say I have a DropDownList server control, called "CategoriesDDL" and the ClientID proeprty determines its client side id, which is its ID prefixed with the id's NamingContainer's ids. In this case the client side ID is CP1_CategoriesDDL. But what is the rule regarding the client side name, in this case "ct100$CP1_CategoriesDDL"?

View 13 RepliesCaching A Server Side User Control?
Sep 8, 2010My asp.net app is heavily using user controls and is high load; my concern is that loading user controls for every request (Page.LoadControl(controlPath)) is sub-optimal at best. I was thinking of caching an instance of loaded user control in HttpRuntime, but I don't know how's it going to behave when multiple connections (threads) will try to fetch it from the cache and modify properties - I guess trouble is waiting there. Any good way to optimize user control loading?
Again, I am talking about caching user control, not it's html output (which it makes no sense caching as it's [html output] going to be different every time you use it)
Run Server Side Function On Dynamic HTML Control?
Jul 28, 2010I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages:
CmsContactUsContent += string.Format("
"<input type='image' value='delete' id='del{8}' runat='server' onClick='DeleteItem' img src='/MaromyDotNet/img/AdminIcons/note.png' style='width:16px;'/>" +
"</div>" +
"<div style='clear:both'></div></div>", message.ContactMessageId);
There is a Class called ContactMessage and I'd like at each iteraion to allow the user to delete the current message through this function:
public void DeleteItem(object sender, EventArgs e)
{
int idToDelete = 41;
BLLContactMessage.deleteMessageById(idToDelete);
}
However, the event does not fire.

but how is ((Alert)Container.DataItem).AlertId grabbing its value?
