I have created a user custom control, and what I would like to do is to pass it the text value from a label where I can carry out some other processing.
I have a very simple user control with 5 radio buttons on it, and 3 properties (ID, RatingSetID, and Rating). On the initial load of the page they are on, the code acquires data and places the data into the 3 properties. However, when the submit button is clicked the page reloads and the 3 properties get reset to 0, they are in the !IsPostBack as well.
I'm constructing a User Control that will have one Property called "ContractIdx". Here's how I've constructed this Property:
public int ContractIdx { get { return Convert.ToInt32(this.Attributes["ContractIdx"]); } set { this.Attributes["ContractIdx"] = value.ToString(); } }
I'm initially loading the User Control by passing a parameter to it and setting ContractIdx accordingly. That all works fine.
Upon Postback though I'm loading the User Control without any parameters and then setting its ID property to what it was before the Postback. My understanding was that if I did this then ViewState would properly restore everything. Yet apparently this is not the case with the "ContractIdx" attribute.
Where am I mistaken in my understanding? How should I change things to get this mechanism to work?
I have a user control which has some properties configured on it. I need to access (actually, only read) the values of those properties on the client. I have done it like this.
Code behind:
[Code]....
ASPX:
[Code]....
That works but, at the back of my mind, I'm sure I've seen a neater way of doing it, although I suspect that may have been on an Extender not a User Control. Pointers on that welcome.
Also, related to that, the User Control itself has an Id which becomes part of the name of all visual objects included within it. However, the User Control is not a DOM element in its own right (because it has no visible rendering) which [I think] means that I have to attach properties to one of the visible elements within it, and not to the control itself?
I have a gridview which I use to add items through the footer and the EmptyDataTemplate. There is a date field. I want to set the default of it to the current system date.
After a new user first registers at the website, I want to force them to first be approved by an admin before allowing them access to the full site. I created different roles in the ASP.net configuration tool that denies them access but the default setting allows them in. How do I go about this?
I'm trying to set the default button to my master page for logging in.
Basically I've got a master page, with a LoginView in it, with a Login control in it, With a button in it... When you press "Enter" I want it to use that as the default button.
(structure in sudo-code if it helps)
BODY Form ID=Form1 LoginView ID=MasterLoginView AnonymousTemplate Login ID=MainLogin LayoutTemplate Button ID=LoginButton
I know I've got to use .FindControl("") but as much as I mess with it I can't seem to get it to hook to the button.
I would like to set a default date, not the current date ( say 31/11/2011) for the calender control. What date format should I be using for the datetime variable so the calender control accepts the date. I have tried using the following date format but I keep getting the error: String was not recognized as a valid DateTime.
[Code]....
Or is there another way to set a date for the calender control.
I am trying to find a way of setting a default image(e.g. file path) for the FileUpload control so that a default image can be used if a user did NOT choose to upload an image.
I am developing one custom control. I dont want default web control property should be in my custom control.For example.[Code]....
When you put this control in the page, you will see default web control property such as Font,Border,Width,Height.... I want to show only those properties that I define in my class.Suppose, I have three property defined in class then only three properties will be visible for control, other default web control proeprty should be hide or invisible.
I need to validate a textbox to ensure the submit date is older than Today. I wanted to use a CompareValidator to do that, but unfortunately the following code doesn't work:
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
I have an ASP.NET web application and at a certain point I do this:mycontrol.stringparameterforjscript = "document.getElementById('" + myotherparam + "').value = 'Hello'";The problem is that this thing does not work.s you can see this sets a javascript in some event of some tag. Well when the page is redered the problem is that my parameter look like this:
Not sure if this falls under security but I figured since its about logging in it might. Anyway. I would like to know if my approach is good. I have set up a login, the Login method is under the User Class which uses validation to my own database (not ASPNETDB). I would also like to set values to that user to use on each page such as a simple label on the home page that says "Hello [UserName]". Code is below, should I separate the User values into a different class? Also once i go to another page (called Home.aspx) I would like to set an ASP Panel to have the username in it. I created a new instance of the User class in Home.aspx but unsure what I would need to go to get this to work. Should I have some LoadUser method after a successful login?
I need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:
For reasons outside my control I have a table containing input and select fields built using regular HTML with the runat="server" attribute (as opposed to standard ASP.NET controls). I am trying to set a value to be selected when the page is loaded based on values being passed from the Session (again, factor outside my control).
Setting the Selected property of the list item does nothing and doesn't select the item in question. How do I achieve this?
the Select portion doesn't work, although it gets executed on the proper item. Should this code be called in a specific event? I believe it's being called in Page_Load; should it be called in Pre_Render instead?
