I am trying to build a web user control and set some default values for its properties in the code-behind like this:
[DefaultValue(typeof(int), "50")]
public int Height { get; set; }
[DefaultValue(typeof(string), "string.Empty")]
public string FamilyName { get; set; }
[DefaultValue(typeof(Color), "Orange")]
public System.Drawing.Color ForeColor { get; set; }
When I add the user control to the page and call it without any properties:
<uc1:Usercontrol ID="uc" runat="server" />
the default values are not set and every property is 0 or null.

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:
<asp:CompareValidator ID="cvtbDateExpiration" ControlToValidate="tbDateExpiration"
Operator="GreaterThan" Type="Date" ValueToCompare="<%= DateTime.Today %>"
ErrorMessage="Card has expired" runat="server" />
The compiler tells me that ValueToCompare="<%= DateTime.Today %>" is wrong: "This is not scriptlet. Will be output as plain text."
Is there a simple way to achieve this (without setting it using the Code Behind)?

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.

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 code is basically this (names generic-ized):
HtmlSelect dropdownList = ((HtmlSelect)myTable.Rows[0].Cells[5].FindControl("DropdownList");
DataSet allListItems = this.GetDefaultListItems();
foreach (DataRow row in allListItems.Tables[0].Rows) [code]....
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?

How do you use the http POST method with a Grid View on another page. I am trying to use the POST method to send the ID from the selected row of a Grid View, I am using a link button set to fire the select command and it has the Post Back URL set, from one page and then retrieve the ID value on another page using an Object Data Source. Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.

I have a user control in asp.net that i need to dynmically set properties for. The propety and property values are in a dictionary, for example:
Dictionary<string, string> propertyValues;
Control c = Page.LoadControl("~/Control.ascx")
I can currently set the properties on the control using reflection, however, with .net 4 and the new dynamic keyword, is there an easier way to do it, for example, something like this:
dynamic c = Page.LoadControl("~/control.ascx");
foreach(var itemin propertyValues)
{
c.item.key = item.value;
}
this obviously doesnt work because item.key is a string and not a property.

I have a custom control with a UpdatePanel inside. Depending of user action or page programing I call Update method of my UpdatePanel to refresh html portion to user.
For example, I created a property called Title. If the Title change i call Update of my UpdatePanel.
[Code]....
But if the Title property is configured on aspx file, my UpdatePanel is always refreshed because my Title property is setted on Init stage of page life cycle.
I need to know if this property is setted on init stage or if ViewState is restored to avoid call Update, or any tips to avoid refresh my control everytime.

I'm trying to set the ImageUrl property after I've uploaded an image so that I can display the newly uploaded image, but for some reason it's not working.
If I navigate from the record I've just updated and then return back to that same record, the image then displays. It just doesn't display right after I've updated it. Basically what I'm doing is this:
Sub FormView1_OnItemUpdated(Sender As Object, e As FormViewUpdatedEventArgs)
Dim MyImage As Image
MyImage = FormView1.FindControl("Image1")
MyImage.ImageUrl = "image1.jpg"[code]....
I've left out the path intentionally because I'm pretty certain that the path I'm giving is correct... again, if I navigate away from the record and then return to it, the image displays. In addition, when I view the "Page Source" to view the resulting html, the src property of the image tag is blank . So, it's not a path issue... the issue is that its not setting the src at all which is why the image is not displaying.

How do you set the id of an Html.Form in ASP.NET MVC 2?
I tried this:
<% using (Html.BeginForm("Save", "Clients", new { id = "SubmitForm" })) {%>
But it doesn't work, my form still doesn't have an id property:
<form action="/TothSolutions/Secure/Clients/Save/SubmitForm" method="post">
I'm guessing this worked in ASP.NET MVC 1 but not 2. The reason I need the id property set is so that I can do jQuery validation on the form: $("#myForm").validate etc...

I am not sure how to explain my current issue. Right now I have a Form that spans a couple of pages. I have divided the Form into multiple section as well including a File Upload section, a File Download section, and have an 'Update' button at the bottom of the Form. I also have Error labels within each section, and have an Error label at the bottom of the Form under the 'Update' button.The problem that I am experiencing right now is that when I produce one of these errors, the Form automatically displays the very top of the page. So in other words, if the error message is displayed at the bottom of the Form, the user has no idea unless they scroll all the way down.Is there anyway to keep the application focus at the area where the button is clicked on? This way if the user produces an error, they will see it right away.
