Web Forms :: Dropdownlist Control Inside Loginview Cannot Be Accessed
May 14, 2010
i am getting this error "A control with ID 'NewAssignTL' could not be found for the trigger in UpdatePanel 'UpdatePanel'. " i have 2 problems i cannot access my dropdownList control from code behind and i triggers cannot access the control.
I've put a DropDownList control within a LoginView control. I've got 2 SqlDataSource controls outside of the LoginView control, with the intent of databinding the items that comprise the ListItems of the DropDownList control, and another one for the data is stored in another table which has what was previously saved for the selection. However, when I've assign the SqlDataSource control to the DropDownList control's DataSourceID for the lookup table, I'm used to seeing the fields from the SqlDataSource control appearing in the DataTextField and DataValueField properties. However, they're not appearing there at all. Moreover, even when I try to type them in, its as if VS 2010 refuses to allow them.
protected void Login1_LoggedIn(object sender, EventArgs e) { LoginName loginName = LoginView1.FindControl("LoginName1") as LoginName; Response.Write(loginName.ToString()); //for now I used Response.Write for testing purposes }
I use master/content page and use this code (below) for validation, if I place the PasswordRecovery outside LoginView the validation is marked up correctly, but placed back inside the LoginView the PasswordRecovery compilation error is CS0103: The name 'PasswordRecovery1' does not exist in the current context.
I have a image CAPTCHA script (downloaded from the web) that I am placing inside a Login control. I have also place that Login control inside the annonymous template of a LoginView control.
When I try to do the image verification the text box to verify keeps coming up Null and gives me an " NullReferenceException: Object reference not set to an instance of an object" error.
I have the same control working inside the CreateUserWizard control so I am not sure what's wrong.
[code]....
I have tried variations for the LoginView1.FindControl("txtVerify"); but this is the only one I have been able to use with Intellisense that does not cause a build error.
However, once the update is finished (and I call e.Cancel = true), the LoginView control does not databind its children... so they are all blank. The FormView's viewstate is still fine, as all the rest of the controls outside of the LoginView appear fine. I even handle the FormView_DataBound event and a Trace shows that the FormView is being databound on postback.
Why then is the LoginView not keeping its ViewState/being databound? Here's a sample code snippet showing the flow:
Hello all i have this little issue getting this to work, i have a dropdownlist in asp.net inside a formview and jquery cant find the control im guessing because its inside a form, this is what i got and it works on another page without a formviewi get this errorName 'Country' is not declared
I have a gridview with columns 'Edit', 'Delete', 'View Results' and other details. The 'Edit' column opens a modal popup to edit the record. The 'View Result' column is in a login view and this column is only visible to users belonging to the group 'Manager' as below:
[Code]....
When the page is first loaded, the hyperlinks are displayed correctly. however, after editing a record and saving the changes, the 'View Results' column loses the hyperlink.
I tried creating a temp hyperlink column outside a loginview control and this seems to work correctly.
i've an UpdatePanel with a LoginView inside, now, inside the AnonymousTemplate i've a Button (btnLogin), the problem is that the Triggers tag don't see the button. here is the code:
I'm using roles based authenication and am trying to populate a dropdown list from Page_Load that resides inside a LoginView control. My problem is my code behind file doesnt recognize controls inside the LoginView templates.
i have used an login control for the users who have not logged in and defined login verification method on the click event of the button but while excuting i do get an error
Error 1 The name 'Login1' does not exist in the current context
I have a LoginView control that contains a PasswordRecovery control. Upon page_load I don't want this to be visible. When the user clicks a hyperlink button ("forgot password?" type of button), then it'll be made visible.
But I'm having a hard time making the password recovery control invisible at runtime. Here is my page_load function:
[Code]....
It is the only password recovery control in the LoginView control, so I don't understand why this isn't working. The password recovery control is still visible when the page loads in my browser.
I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.
I have a LoginView in my APS.NET application with AnonymousTemplate and LoggedInTemplate. I've put LoginStatus control inside LoggedInTemplate but it doesn't work as expected.
Here's the code
<asp:LoginView ID="LoginView1" runat="server"> <AnonymousTemplate> <asp:Login ID="Login1" runat="server" OnAuthenticate="Login1_Authenticate" DisplayRememberMe="False" PasswordRecoveryUrl="/" DestinationPageUrl="/"> </asp:Login> </AnonymousTemplate> <LoggedInTemplate> You are logged in as <asp:LoginName ID="LoginName1" runat="Server"></asp:LoginName>. <asp:LoginStatus ID="LoginStatus1" runat="server" LogoutAction="Redirect" LogoutPageUrl="/" onloggingout="LoginStatus1_LoggingOut" /> </LoggedInTemplate> </asp:LoginView>
All event handlers are correctly defined in code behind file.
The problem is that if user logs in he will see his user name with logout link from LoginStatus control. Clicking the logout link takes the user back to login form (both login and logout form are part of the same user control) but if I refresh the page the user is still logged in.
I've noticed that if I move LoginStatus control outside the LoginView then logout process works as expected. I've also noticed that when LoginStatus is inside LoginView then it doesn't raise a loggingout event.
I hav a gridview in which i display the project name,created date,Start time ,end time ,total hours along with the task id field which is visible=false.

There is a UserControlA which was already developed when I joined on a project. It is in a Project which I will call MyProjectWeb and it's namespace is MyProjectWeb.Common.
[code]....
But to my surprise, I cannot create an instance of UserControlB in the same code file in WorkFlowManager. MyProjectWeb.Common namespace does not even contain a UserControlB. When I compile I get obviously get a The type or namespace name 'UserControlB' does not exist in the namespace 'MyProjectWeb.Common' (are you missing an assembly reference?)
Why is that I can reference UserControlA but not UserControlB which are in the same namespace from the WorkFlowManager cs file? If I access the MyProjectWeb.Common namespace anywhere inside the MyProjectWeb, I can see both the user controls. Anywhere to look for errors?
