Unable To Access Dynamic Controls Inside Ascx Using Javascript On Aspx Page
Jun 2, 2010I have a user control (ascx) which contains a control (hidden field). In the page_load event of ascx, i have the below code:
HyperLink.Attributes.Add("onclick", "JavaScript:return AccessControl('" + hdnField.UniqueID + "');");
Note: The hidden field resides in .ascx file.
I want to access this hidden field at runtime and i have the below javascript function in aspx page that loads the usercontrol.
function AccessControl(hdnFieldId)
{
var ctrl = document.getElementById(hdnFieldId);
alert(ctrl);
I am getting 'null' value in the alert. I tried using 'ClientID' and 'this' instead of 'UniqueId'. I am wondering why this is not working. I am using .net 2.0.
Security :: Unable To Retrieve Current.User.Identity.Name In II7
Feb 26, 2010I'm in the middle of moving a web application from IIS6 to IIS7. I've enabled "Windows Authentication" and added <deny users="?" /> to the authorization section of my web.config file. When the app was running on IIS6 my users where able to access the web app without logging in because their windows login was automatically recognized. This does not seem to be the case in II7. I can not get a value for "Current.User.Identity.Name" in my ASP.Net code.

View 2 RepliesExport Current ASPX Page To PDF?
Feb 24, 2010Hi- I have a web page that uses a combination of gridviews and html elements to create a report. I would like to give the user an option to click and it will export to a pdf. I would prefer not to create the pdf on the server as that requires me to write another process to clean up files.
Optimally, I'd like the current page to open a new page that renders the pdf and prompts the user to save it/open it.
I've looked at iTextSharp and am interested in using it if I don't have to specify every element. If there is a way to specify a panel and all of it's contents or an alternative, I'm open to that too.

View 2 RepliesGet A Reference To The Current Class (ascx Or Aspx) Given A Member Object?
Mar 14, 2011Given an instance of a control SomeControl that is in a some file (could be a usercontrol/ascx, or an aspx) how can I get a reference to the class to which it belongs?
In a usercontrol, SomeControl.NamingContainer seems to be reliable.
In a page that inherits from a MasterPage, this will return a reference to the ContentPlaceHolder, not the actual class that defines the aspx. What I would want in that case is SomeControl.Page
Parent will return the parent control in the heirarchy so isn't much use.
Is there any method for getting this directly regardless of what kind of thing it is?

Security :: Unable To Use Profile In .aspx.cs Page In .net 3.5
Nov 12, 2010I'm trying to use Profiles so I could get/set FirstName, LastName for users. I have installed the tables (from aspnet_regsql tool, that also installed membership), the web.config looks like this:
<profile defaultProvider="AspNetSqlProfileProvider" enabled="true">
<providers>
<!--<clear />-->
<add name="AspNetSqlProfileProvider" connectionStringName="LocalSqlServer" applicationName="/" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral,

The problem is that I have no idea how to get/set FirstName, LastName. I'm reading from Apress book (Beginning ASP.NET 3.5 From Novice to Profesional), they say simply write: Profile.FirstName ..... but when I write Profile intelisence doesn't display, it displays ProfileManager and the like.

Mar 17, 2010I want to set focus to textbox B after a user has entered data in textbox A. Both textboxen reside within custom controls which reside in the same accordion pane. The custom controls override the Focus method and set focus to the textbox they contain. Focus works fine until I place the controls inside an accordion pane.

View 1 RepliesWeb Forms :: Unable To Access Hidden Textbox Value In Webpart On Aspx Page
Jan 7, 2010I have a requirement where I have a webpart and two ImageButtons(imgGV, imgLV) and a hidden input textbox('ctl00$MainHeaderContent$txtType') in an aspx page. I need to change templates to this Webpart either to show results in "Grid View" or as "List View" on the click of this ImageButtons. I added code in the page_load of .aspx page as
imgLV.Attributes.Add("onclick", "document.getElementById('ctl00$MainHeaderContent$txtType').value='LV';return true;");
imgGV.Attributes.Add("onclick", "document.getElementById(('ctl00$MainHeaderContent$txtType')).value='GV';return true;");
When I am clicking the specific ImageButton, it has to write into hidden field either "GV" or "LV". In the webpart CreateChildControls I assign templates based on the text in Hidden field either "GV" (Grid Template) else "LV" (List Template). In the CreateChildControls of Webpart for the template change, I am getting the Hidden value as empty. I am using coding as
HtmlInputHidden t = new HtmlInputHidden();
t = (HtmlInputHidden)this.Page.FindControl("ctl00$MainHeaderContent$txtType");
if (t.Value=="GV") {
assign one template}
else { another template}.
I am getting t.Value="". Question is: Is it like if we add some text in a hidden textbox using the Javascript function in an aspx page, the same textbox value in the same aspx page but in the Webpart class in the CreateChildControls method using the code as this(webpart).page.FindControl("Textbox").text is showing empty. So the text added using Javascript into Textbox is it not available in the code behind code using "Text" property of the same Textbox?.
