New users can register on my site by completing a basic form that has the create user wizard control with some additional information i am collecting using a CheckBox List. They can then log in to the site and and view "MypProfilePage.aspx" where I display the information with the CheckBoxList boxes already ticked based their selections which they can update. My problem is I have two levels of User and each one has a different registration form.
Registration Form A
Has 20 Items in the CheckBox List
Registration Form B
Has 10 items in the CheckBox List
On the Profile Page, I just want to show the CheckBox which is relevant to the Registration form A or B and with selections by the registered user. So therefore the User who registered on B will not be able to see the selections checkbox list for A.
I have a ListView in my system..
And inside it, there is a button called "Delete".
In the behind code, I tried to access the button control in the listview. However, the code keep looping non-stop..
The logic is the Delete button will only be visible by the current logged-in user. And I had already set the button as visible = false. I had set breakpoint to the line : Delete.Visible = true;. Once the execution reach here, it loop back to the first line again..
And Delete button remain invisble despite the execute visible = true statement..
Here is the code:
protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
MembershipUser currentUser = Membership.GetUser();
Guid currentUserId = (Guid)currentUser.ProviderUserKey;
[Code].....
I am using the ajax reorderlist control from the latest Ajax Control toolkit. Based on the logged on user, I need to hide the "edit" and "delete" links. They should be visible to admin, and not visible to others. I used to control this when I was using a gridview just by calling the column and setting it's visible property to false. I have tried using:
ReorderListMinutes.TemplateControl.FindControl("lnkDeleteAgendaItem").Visible =
False
ReorderListMinutes.TemplateControl.FindControl("lnkEdit").Visible =
False
This returns an error of the dreaded "Object reference not set to an instance of an object."
When i run the following code it the error as :
""Object reference not set to an instance of an object.""
Protected Sub CreateUserWizard1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles CreateUserWizard1.Load
Dim SQLData As New System.Data.SqlClient.SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True")
Dim cmdSelect As New System.Data.SqlClient.SqlCommand("SELECT TOP 1 EmployeeId FROM a1_admins Order by Id DESC", SQLData)
Dim label11 As Label = CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("Label11")

View 3 RepliesI am creating a function to hide all the gridview controls except the control whose name is being passed in the function.
Here this.Controls referes to controls present in the page (At compilation error is thrown although). I want to fetch all the controls of type GridView with Name property not equal to the one passed in the funtion.
Now after getting a collection of GridView. I want to hide all the grids
private void HideGridView(string gridToShow)
{
GridView[] result = from control in this.Controls
where control.GetType() == typeof(GridView) && control.Name !=gridToShow
select control as GridView;
foreach (var control in result)
control.Visible = false;
}
At comile time it shows me this.Control as invalid because it is not a collection.
How can I achieve this on a web application
EDIT:
private void HideGridView(string gridToShow)
{
(from control in this.Controls.OfType<GridView>
where control.Name !=gridToShow
select control).ToList().ForEach(gv=>gv.Visible=false);
}
Here is the code I wrote, shows me an error: GridView is a type but used like a variable (Compile time error).
And at where Invalid Expression Term 'where'

View 1 Repliesi have a doubt difference between object code and embeded code .
View 2 RepliesI have the following scenario. An user uses the desktop application to call our WCF Service which has windows authentication. The WCF Service calls the Office Communication Server (OCS) in order to do some custom work.
When the WCF Service calls OCS we have to pass an instance of NetWorkCredential into the call. I want to pass in the original calling users NetworkCredential object into the OCS call rather than constructing it using a custom username and password. How do I get access to the calling users NetworkCredential object from the WCF service and pass it to the OCS call?
I am looking for a solution to a Java Script question. My question is this, I have a gridview, and in this gridview I have a column, which I use as a flag. The gridview itself is dynamically added to a user control and then to the page. What I would like to do is to use Java Script to hide this column, but I do not know how to do this. Unfortunately, I cannot use code behind, because of the gridview being dynamically added. Also, I have one further question, I already have some Java Script code that can hide some of the rows based upon the values in my column when a button is clicked. What I want to do is when the page is loaded for the first time, to hide some of these rows, and to use the button in reverse to reveal them again. How do I achieve this?

In a button click, I need to be able to hide my ModalPanel and then continue running other code server-side. I currently have it this way:

Basically what I'm trying to do is the following:
1. Button_display in my webform simply displays my UpdatePanel via ModalPopupExtender.
2. Button_closePanel_Click will hide my UpdatePanel and then run some server-side code, which would display my UpdateProgress control.
protected void Button_closePanel_Click(object sender, EventArgs e)
