I have a hyper link control and I set the NavigateURL and the ImageURL property at runtime. I also need to set the class of the image tag that it generates but I cannot figure out how I can do that. The solution mentioned here [URL] does not work because the image url is hard coded.
View 2 RepliesI have a set of links that exist in the master page. I have a css class i would like to assign to a particular one of them depending on if that is the page you are at during page load. ex: Home will have the current_page_item class if you are at the index page
This is what I have:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
DirectCast(Me.Master.FindControl("ctl00_homeLi"), HtmlGenericControl).Attributes.Add("class", "'current_page_item'")
End Sub
i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).
i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...
... that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below...
Partial Class FPDataContext
End Class
I'm using VS2010 RC and am just developing an MVC 2.0 app where i want to be able to use the UI Annotations such as [UIHint("RelativeDateTime")]
edit:
here is my VB version edit as an example...
Imports System.ComponentModel.DataAnnotations
<MetadataType(GetType(CommentMetaData))> _
Partial Public Class Comment
End Class
Public Class CommentMetaData
<UIHint("PostedSince")> _
Public Property DateAdded() As DateTime
End Class
I have a DropDownList and need to know its name in the code behind:
<select name="ctl00$cphMainContent$ddlTopic" onchange="javascript:setTimeout('__doPostBack('ctl00$cphMainContent$ddlTopic','')', 0)" id="ctl00_cphMainContent_ddlTopic">
<option value="All">All</option>
</select>
I need to get the value "ctl00$cphMainContent$ddlTopic"
VS 2010 crashes instantly when I press = when adding the class attribute to anything.
The exact error I get is
Microsoft visual studio 2010 has stopped working.
Adding any other attribute works fine.
My question is dealing with the DataList control. I am trying to add a click event to the rows of the "table" in the OnItemDataBound event.
The problem I'm having is I can't get a reference (through a row id attribute) to the "row" being generated by the DataList control (and more specifically the item template). Is there a way to add id attributes to the rows being generated by the item template?

I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

I have created a asp.net webpage for viewing daily downloaded newspaper, saved as a pdf file in a selected folder (~/NEWS/{0}) within the web root directory. Also i have a SQL datasource linked, where the news table has two columns viz: date and filename.
I want to create a tiled listview where the date text is visible on the hyperlink. on clicking the hyperlink, the file name is retreived for the corresponding date and the pdf file opens in a fresh page.
I have tried going to the item template in listview and replacing the label control with a hyperlink control, but then not able to successfully proceed ahead.

View 3 RepliesI've got problem with generating ajax anchors. I'm using simple
Ajax.ActionLink("test", "Test", new AjaxOptions { UpdateTargetId="test", HttpMethod="GET" }) and the generated markup is:
<a data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#test" href="/Home/Test">test</a>
which, obviously lacks the onclick="Sys.Mvc.AsyncHyperlink.handleClick(...)" attribute.

Language="VB"
CodeFile="MasterPage.master.vb"

<!DOCTYPE

I have a reports UI that allows users to select the reports that they want to run. I want to be able to display each selected report in its own window so the site does not navigate away from the reports UI. Is there a way to acomplish this? Maybe through the response object? UI Summary
The user selects the reports from a list then clicks the run button. On post back the selected reports are placed in a collection and redirects to a new blank page that will prompt for any parms, render the report, remove the report from the selected reports collection, and redirect back to the reports UI. If reports still exist in the selected reports collection it redirects to a new blank page until the collection is empty.
Is it possible to specificy height and width dimensions of the ImageUrl attribute in a <asp:HyperLink> control? I tried setting the height and width attributes of the HyperLink control thinking the picture specified in the ImageUrl attribute of the HyperLink control would be resized to the dimensions of the height and width attributes but it wasn't.If I can't somehow resize the specified image for the HyperLink Im gonna have to scrap the control and do it the old fasioned way. By using a regular <asp:Image> control inside an <a href>.
View 3 RepliesI am converting a web forms site to MVC and there are a lot of pages all with an individual screenshot image on. Rather than have a separate page for each screenshot image, I though a better way to do this would be to have one page, and to pass the image details into a Controller method, and then set the src value of the <img> in my code. Does anybody know how to do this, and even if it is a good idea to be making reference to UI elements in my Controller code?
View 6 RepliesI want to add a class to a div inside my repeater control based on whether the query string value is true or false, so that I can style it differently.
View 6 RepliesI wrote a function in code behind of the aspx file to get from an SQL database the imageurl and assign it to that image's URL. This works fine so I decided to move it to a class but now the imageurl does not exist because the passed image control is now refering to system.drawing.image not the web image.
Code:
Public Sub ShowCodeImages(sProdCode As String, ByRef imgCode As Control, sConnectionString As String)
Dim sSQL As String
Dim sqlDCStock As New SqlConnection
Dim sqlDAStock As SqlDataAdapter
Dim sqlDTStock As DataTable
[Code] .....
