Web Forms :: How To Add String Property
Mar 20, 2010
I have this tag in my webfom
<img id="takeimg"
alt=""
src="images/i.jpg"
data-zoomsrc="images/i.jpg"
border="0"
runat="server"
width="130"
height="90"
/>
this works fine, whenever i mouse over on image even its works perfectly. problem is when i pass it dynamically as given below,it doesnt work, how to fix this how can i add "data-zoomsrc" dynamically. I can set Src property dynamically, but how can i set data-zoomsrc.
<img id="takeimg"
alt=""
src="<%=getimg %>"
data-zoomsrc="<%=getimg %>"
border="0"
runat="server"
width="130"
height="90"
/>

So I have this object I'm creating, just to hold some string and boolean data that I want to pass to the second page. So I have a class file:
[Code]....
[Code]....
And I'm setting values from form controls, like this:
[Code]....
So here is the really weird part: if I try to set a label's text property equal to objPrimaryScreeningData.myMemberVariable after selecting it - there is nothing there. I'm sure it's a stupid mistake - being self taught stinks.

I'm tyring to write a simple DetailsView only used for inserting new records that will pre-fill a textbox with a query string value. Here's the DetailsView:
[code]....
All I want to do is set VenueID_FK.Text to = the "VenueID" querry string. I also want the user to be able to see the VenueID number as they are filling out GridView1.
I know this is probably a simple thing, but I am very new to asp.net. I thought I could handle this in the page load event, but when I try something like this
TextBox VenueID_FK = (TextBox)DetailsView1.FindControl("VenueID_FK");
And then follow by setting the Text property programitically. I've accomplished something similar to this on a different page using a FormView, but only for ReadOnly mode and it was handled in the databound event on that page.
I get the error "The name 'DetailsView1' doesn't exist in the current context." when trying to do the above mentioned. When trying the same line in the databound event here, I get the same error.

controltype = "label" propertyname = "Text"
controltype = "Image" propertyname = "ToolTip".
so I have something like this in my code:
List<Control> controls = GiveMeControls();
foreach(Control control in controls)

I got an unusual problem. The solution is most likely very simple or completely impossible. I want to dynamically select a property based on a string value. I am using LINQ which automatically creates a class for each table. The actual columns in the table become properties of the class. I need a different column based on the current culture settings as the different columns contain translations. For example, if I want to set the text of a hyperlink to English I choose the EN column as follow:

I'm trying to reference a public property from a string. How can this be done in vb.net? I have the text value of "FirstName" stored in strucParam(i).TxtPropertyName.
This is what I'm currently doing:
Dim tmpValue As String
Dim ucAppName As UserControl_appName = CType(Parent.FindControl(strucParam(i).ParentFindControl), UserControl_appName)
tmpValue = ucAppName.FirstName.Text
How can I use the value in strucParam(i).TxtPropertyName so that I can remove ".FirstName" from my code?

I am getting above mentioned error when I try to run the following code:
Private strConnString As String = ConfigurationManager.ConnectionStrings("conString").ConnectionString
Private con As New SqlConnection(strConnString)
Private pID As Integer
'FIRST SECTION
Dim query As String = "query"
Dim cmd As New SqlCommand(query)
[Code] .....
The error is coming from the second SQL cmd but if I comment out the first section; the second section runs fine.
I must have made another basic error but I just can't figure out what it is.

In the original site, master page has code-behind to check a query string parameter value. Depending on this value, code-behind dynamically modify some CSS property to hide / display master page elements.
As MVC2 has no code-behind because we are supposed to perform everything in the controllers, how should I proceed in this case ?
I see this : [URL]
It partially answers my needs but the query string processing is common to all pages. How can I move this processing in a common code section ?

Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.
[code]....
As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.

my web application i use FindControl to retrieve a Control By Name (it returns an System.Web.UI object). The control can be of various type and I don't want to treat them differently: I'd like to set the Text property to a defined string. I hope there's a class that I may use to cast the control and set the Text property.

So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.

Is there any difference between accessing a property that has a backing field
private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?

In the Web.Config we have a timeout property. Ex:
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="2880"/>
</authentication>
When loggin in, we can specify a ticket expiry date. Ex:
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, id.ToString(), DateTime.Now, expiryDate, true,
securityToken, FormsAuthentication.FormsCookiePath);
Why there's two places where I can set expiration info about forms-authentication? What's the difference between them? What has more relevance?

I have a masterpage that contains all the javascript and inside the content control, there is a link that calls a javascript function and I want to pass the id once it's rendered differently by the server.
<asp:TextBox ID="txtstart" runat="server" Width="20%"></asp:TextBox>
<a title="Pick Date from Calendar" onclick="calendarPicker('<% txtstart.ClientId %>');" href="javascript:void(0);">
However, I keep getting this error:
Property access must assign to the property or use its value.
How would I be able to accomplish this?
