I would like to know how can I easily customize my detailsView that when it is in Create mode ID field should be invisible I can rememebr that it was sth like visible = <% code here ... (IsCreated ??) here is an example:
Say I have a DetailsView with a bunch of fields, and I want only certain kinds of users to edit a few of them. They're too few to split them into another DetailsView, so what I'm thinking is to find some way to only allow a user to edit them based on some code-behind logic, effectively making them read-only at will.
I feel it's important to mention that the fields are both TemplateFields, not normal BoundFields with ReadOnly properties. For some reason the required functions don't jump at me from reading the documentation. Oh and I need eveyone to see their specific values, I just want to restrict edit access to them.
I have 2 fields in my gridview one called ScriptType the other BagNo, when a user click the edit button, I would like the BagNo filed to be disabled if the ScriptType field is = "TTA" and enabled otherwise. How can I do this?..something along these lines see below..I am using VB..
I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then DetailsView1.DefaultMode = DetailsViewMode.Insert Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox) txt1.Text = "administrator" End If
But this returns an error of "Object reference not set to an instance of an object." how to accomplish this - either using the method above or another method? The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"
I have a dropdown list named "ddlCustomerDatabase' . Now this dropdownlist is associated with a sqldatasource. Now what I want is when there are no values in the dropdownlist ddlCustomerDatabase ie no row in sqldatasource asssociated with it, I want to make it invisible that is ddlCustomerDatabase.visible = False else it should be visible.
I have used IF ddlCustomerDatabase.text Is Nothing THEN,....used IF ddlCustomerDatabase IS Nothing THEN......used IF ddlCustomerDatabase.selectedItem, selectedValue, items.count THEN.. But to no avail.
So what should be the proper logic for achieving my simple goal, to display the dropedown list when it has something else to just make it invisible when it is empty.

I build some html in my page's code behind and set a radio button's text property to this string of html. The html contains a link, PDF Preview.
The first time my page posts, I want to display this html and subsquent times I don't. But there are data in the html that I need, so I want to still build it and have it available but not have the user see it. None of these worked; it was always still displayed:
I was given some code a while ago which hid certain nodes from the TreeView but allowed them to appear in the breadcrumb.
Here it is:
[Code]....
I later needed do the same thing but, by now, was using C# instead of VB.
I've tried to translate the VB into C# but the code doesn't work. It doesn't report any design time or run time errors; it just doesn't work (the nodes ARE visible in the TreeView.

Getting familiar with ajax tabs...watched Joe's video. Am building simple wizard with first tab visible, others invisible until "next" is clicked. I know I need an onclientclick event but am very elementary with Javascript and .Net doesn't prompt javascript.
I've run into this before, but I was using a formsview and just changed the field to hidden. I am trying to get the value of a cell out of a gridview to a variable and here is the code:
[Code]....
This works perfectly if column 6 is visible, but because it's an id number (which is not the primary key) I do not want it visible, but changing it to visible="false" causes this code to return null. Changing it back to visible and it works.
I'm not sure why the visiblity of a control changes the functionality of it.
I have a formview which contains a question and 5 checkboxes with answers alongside. Some of the questions are true/false so I want to make checkboxes 3, 4, and 5 invisible.
Should this be handled in code-behind? (I don't see any ready-made events for paging through the formview) or is there a way to test data and change the visible property in;
I m getting 9 columns from database in a dataset but I want to diplay only 4 columns in datagrid. Remaining 5 columns values, I want to display in the textboxes below datagird.
I tried it making column invisible. If I make it invisible, I m not getting any value for that column to display in the textbox.
I have a panel on a form with textboxes on. How can I make this invisible while editing the form in 2008express? I want to add another panel on top and be able to add stuff to it without the other getting in the way.
I bound the gridview having some fields(ID, StudName, City) and Display Button. When I click on the Disply button I approve the student and updation will happen.
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :
<%# Container.DataItemIndex+1 %>
and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?
I have a Save button in my page. When user clicks it, the program will do some checking. If it passes the test, the record will be saved. If not, it will fire another button's onclick event. The 2nd button has been set with both height and width = 0 and it has an extender AJAX ModalPopup.
Here is the code for the 1st button (the visible Save button):
[Code]....
Problem is that setting height and width = 0 for the 2nd button can make the button invisible in IE. But it shows a very small button in Chrome. If I set the 2nd button to invisible, it simply won't function at all.
i have just started making an asp document using c# codes
[Code]....
right now i have a droplistbox in my design.. when i select others, a text box will appear and allow user to enter the new email address. however, i would like the text box to appear invisible to the user when he enters this asp page initially. how do i go about doing it?
just another question.. Supposed that if the user chooses "Others" and entered a new email address in the textbox and i want him to be able to see this new email address as an option in the future when he runs this asp file again. is it possible not to set up a SQL server for my application? or can i just use some variables to set as that?
