Failed to FindControl on Web Page

Posted By:      Posted Date: September 29, 2010    Points: 0   Category :ASP.Net


I got a content place holder, in this holder, I have a grid view. Inside this grid view, I will have multiple textbox added at runtime.

From the source code, I found that one of the textbox's id is as "ctl00_CPHDetail_gvDetail_ctl02_txt_Text1", CPHDetail is the content place holder, and gvDetail is the grid view.

What I wanted to do is to find the text box control and retrieve its value.

So far, this is what I have done, and it was able to return the correct info up to the grid view. It can never find the text box control.

I wonder will it caused by the ct102 between "ctl00_CPHDetail_gvDetail_ctl02_txt_Text1"

ContentPlaceHolder myContent = (ContentPlaceHolder)Page.Master.FindControl("CPHDetail");
GridView gvView = (GridView)myContent.FindControl("gvDetail");
TextBox tb = (TextBox)gvView.FindControl("txt_Text1");

Pls advise.

I have 2 web pages. First page has a textbox and a button control.

when I enter test and click on the button , system goes to the second page. And in the second page I want to access the Textbox in the first page. When I try to do this I get the following error.

"Object reference not set to an instance of an object. Following is my code :

Dim txt As New TextBox

' Find the server name on the previous page
txt = CType(Page.PreviousPage.FindControl("TextBox2"), TextBox)
If Not IsNothing(txt) Then
Response.Write("[Name Not available]")
End If

I know I could do this with session, but I want to use the Page.PreviousPage.FindControl. Any help is greatly appreciated

MySite user profile site creation of My Content page is created as provisioned failed (unprovisioned

I've been trying to troubleshoot our User Profile Sync and have noticed the profile pages weren't getting updated with everything.  Most content was but things like memberships and the content tabs weren't.  I also saw this error in ULS: ProfSynch: Exception attempting to enumerate site 25a72070-4249-4698-ae99-c2a45d25b08e for ContentDB 23a6e3ef-6d56-4bde-825e-95c6924e2f91: Microsoft.Office.Server.UserProfiles.ProfileSynchronizationInternalException: ProfSynch: The site with ID 25a72070-4249-4698-ae99-c2a45d25b08e cannot be synchronized due to an unprovisioned root web.      at Microsoft.Office.Server.UserProfiles.SiteSynchronizerCollection.GetSynchInfoForSite(SqlDataReader dr, SynchInfo info)      at Microsoft.Office.Server.UserProfiles.SiteSynchronizerCollection.<get_Elements>d__0.MoveNext() I checked in the MySite database under the webs table and noticed all the My Content sites for all of our users had the flag column with the number 1315 in them - (meaning unprovisioned as the error above states).  Cross checking with the User Sync Profile database under the SiteSynch table I noticed all of the sites have NULL for the value under both the LastSynch and ChangeToken columns (The User Profile Service Application - User Profile to SharePoint Full Synchronization  timer job takes care of populating that).&

Trying to declare asp:HtmlLink on my aspx page and failed


I am trying to add CSS dynamically to a page. Does anyone know how to declare asp:HtmlLink on your aspx page?

I tried to add <add tagPrefix="asp" namespace="System.Web.UI.HtmlControls" assembly="System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=A2BXZ856AD71A42XY"/> inside Web.config (under pages and controls) and it successfully compiled. However, I was not able to use the asp:HtmlLink control on my page.

Thank you for your suggestion :)

Changing the graphics on the home page of a SharePoint site

When you create a site in Microsoft Windows SharePoint Services by using the default Team Site template, the home page includes two default graphics. A Windows SharePoint Services graphic appears in the body of the page, and a picture of a house in a circle appears near the site title. You can change these graphics to customize your site. Changing the smaller graphic requires a Windows SharePoint Services compatible Web page editor

Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?


Launch CMD File From ASPX Page


My organization uses a CMD file to install updated files for a major enterprise application. Currently, we send out an email to users with a link to the file and instructions to run it, BUT inevitably users don't update their machines until their in field and try to start the app.


We're now liking the idea of using an ASPX page to prompt the users to run the updates and to capture the fact that the updates have been run. I realize that we can't capture the success or failure of the update. But we'd like to capture the user accessed the page.


Is it possible to embed into the markup for the page a link to the file on the local intranet that the users can click on to run the file?

The user accessing the page would capture that they did just that. We'd deal with wether or not the update was actually installed or if it failed later with them directly.

Need help redirecting users to personalized page


 Hi, first timer here so be gentle.


I've been able to create a cool little website, it's up and running with users logging in and out, I created roles so my administrative team can see sensitive data that's not available to regular and anonymous users.

Now they would like me to create a page specific to each user.  For instance when user A logs in they are redirected to a page that has information that pertains to user A only (like a list of their benefits/ their remaining vacation time). This page needs to be accessible only to user A. 

I've watched a ton of the videos but have yet to see one that covers this topic, any help would be great!!!

Retrieving a variable from a previous page



I'm looking to have a search page where a user will select an item from a listview, then then taken to another page that wil display data based on their original selection.

A user will type in a string and be presented with a list of usernames that are like that string, when they select a user name who's profile they would like to view I would like the page that they're taken to, to be that users profile.

How would I transfer the variable from the search page to the profile page, and when I work on the profile page, how can I access that variable?


Dynamic page customization in WebForms



I am developing an ASP.NET Webforms application for job advertisements. The application is hosted on my own server and enables registrated users to publish job advertisements with the possibility to submit job applications directly from web. The application essentially consists of two parts: job advertisements and job applications sub-apps. 

The job advertisement application uses RESTful approach, implemented as ASP.NET routing and makes no use of different state variables (like viewstate). I provide custom layout of job advertisement webpage for every client using XML serialization of my internal JobOffer class and using XML ASP.NET control with custom XSLT transformation sheet plus CSS to render the custom design. It is all fine and works perfectly.

The second (job applications) part provides users with a custom webform, which is partically dependent upon the original advertisement (regarding the minimal education level, eligible citizenship or work permissions, licences etc.) and can be tweacked using custom CSS. There is, however, no possibility for custom layout of the elements on this page, which provides a multi-tabbed navigation for different parts of job application. Hence the question 1 (see below).

The application is not ready yet, but I intend to keep it hosted on my own server and provide just some ki
