I am writing an application that does it's own logging in a SQL table. On each page, I statically assign this variable: Dim page = "page_01.aspx" I've noticed that page is ALWAYS equal to the name of the Partial Class of the code-behind + the suffix ".aspx" Is there any way to programatically set the string to equal the name of the Partial Class, so I don't have to statically code it on each page? Basically, I want to assign the name of the current class to a string, and append ".aspx" to it. Can I do this, or does that get lost in the compilation?

my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.

I am trying to call web reference "A" in an application.
The web reference "A" will then call a function in another web reference "B" through HTTPS connection (require certificate).

I have problems building a GridView programmatically. My code is:
[Code]....
This displays the GridView with the following problems:
1. The Html constructed in the Subject column displays on the page as raw Html. The source code shows the Html characters in their ASCII form. The function HTMLEncodeSpecialCharacters is obviously incorrect.
2. The PagerSettings display the page numbers only (1 2 3 4) and not the First and Last text (want to display << 1 2 3 4 >>) despite setting PagerSettings.Mode = PagerButtons.NumericFirstLast.
3. Clicking the page numbers is always one page behind. For example, when the page is opened, page 1 displays. If I click 2, page 1 still displays. Then click 3, page 2 now displays. Click page 4, 3 displays. Click 2, 4 displays etc etc.
4. The column headings are aligned in the centre despite setting HeaderStyle.HorizontalAlign = HorizontalAlign.Left.
I remember I read a tutorial at asp.net. The tutorial is to add a row to display the category name before a different category starts in a GridView that displays products ordered by category. But I cannot find the tutorial anymore.
View 5 RepliesI have a datalist in my site which displays html tables filled with data from a sqldatasource. I need to be able to remove one column from the table and put it back again (including the tags in my table which pull the data from the datasource e.g. <%# DataBinder.Eval(Container.DataItem,"Forecast1") %>) I need to be able to do this because I have options to change the sqldatasource query, and I need to alter the table to keep it compatible with the query. What is the best way to do this?
View 4 RepliesI have a GridView which pulls info from a SQL DB. It works fine. I use a CMS to upload the data which includes thenumber referred to below.
The last (rightmost) column in the GridView is a number.
I'd like to know how to know how to:
1) Make a further column visible (to the right of the number) which contains a Button BUT only when the user is logged in.
2) Make that Button call a function (the workings of the function are irrelevant here) and pass to that function the number in the previous column.
I know I could use a LoginView with two GridViews, one for logged in (showing the Button) and one for anonymous (without the Button), but then I'd have to put the Button in the database... I think.
A better idea would be to add the Button column programmatically.
how this can be done and how the Button in each row, when clicked, can pass whatever number is to its left as a parameter?

I've tried to get a list of the IDs of the controls, but when I try to access he ID field of control at index 0 I get a null reference exeption, even though the collection has a .Count == 5. Any clue why or if it can be done and how? I've tried this both in Page_Load and off a button_click event.
Assuming you need the ID to set the proper tab index via the control collection object, the following code should produce the list of the names of the 5 controls. The output is '01234' to the multiline textbox... (the values of x)

How can I programatically call a gridview row when it is loaded based on the primary key. For example, say I have a record in the gridview where the column name is ID (Identity Field) and has the number 37 in it. When the gridview loads up, I need to get the rowindex where the primary key = 37 and have that row automatically selected.
View 5 RepliesI have already google the question, but couldn't found any relevant post.1) I want to make gridview's one column () editable according to some boolean value (flag). If flag is true when the edit is clicked, related column would be editable (text field), otherwise related column would be label.2) Same again, I want to make enable delete button in some rows and not some rows according to that flag.
