I am using mobile list control inside that i inserted a label when i bind any dataset to that list it is not displaying any information. In msdn it is mentioned the mobile list control is equivalent of web control is datalist. The code as follows.
I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.
The example is given below( I am reading the book Sams Teach yourself ASP.NET 2.0 by Scott Mitchell. page 628)

I have two listviews. The inner listview (InnerListView1) is in the SelecttItemTemplate of the outer listview (OuterListView1). Both listviews are bind in the code behind. The outer listview displays correctly in the ItemTemplate. Neither Listview Listview displays in the SelectItemTemplate. Both should display when I click the Select button. I just get a postback (flicker). The display should include the selected record of the outer listview and the inner listview.
How would I go about displaying a databound dropdown list in a property grid, i.e. a dynamic list that can be used to set the value of an individual property?

I want to produce a relatively simple webpage which would contain a drop-down list and a button. When the user makes a selection on the drop-down list and clicks the button (or image), the page would query a SQL database and output the results of that query to an iFrame that would be embedded in the lower half of the page. I've managed to figure out the necessary code for populating the drop-down list by using a stored procedure, and I've managed to figure out a way of having the resultset displayed on a second page but I want to now finesse it and get all of the information displayed on a single page.
I need to query a database and return list of names, then I need to display their pictures and information in a Web Page, using ASP.NET or using JavaScript. The main concern is displaying the pictures and information dynamically on the page in an organized way.
Normally I dont have the login link in the master page. But I have the labels to display the user information on top of master page once logged in and have the sign in option in content page which contains that master page. After sign in , i want to display the user information on the top of the master page without redirecting user to the same page? How can we do this?
I am using Visual Studio 2010 with Access database. The customer table has 2 columns, Names and Emails. I want to
display and bind the data for all of the names from the customer table in a bulleted list. (Extra work) Then I want to make each name link to their corresponding email address.
How can I do it? Can I use GridView or SqlDataSource?
I've been asked to create a page which will provide identical information from another page. The key thing is, from my understanding, that it is not data driven it's from a txt file wich is updated. This info will need to be reflected on the page I'm going to create. how to "pull" or get the information w/o the help of database?
I have a DropDownList within the ContentTemplate and wonder if there are any special considerations I should be aware of filling the list with data prior to displaying the TabPanel?
i was wondering if there is a way to prepopulate sharepoint list item values into a webform fields if the loggin user's information is matched with the information in the list item.
what i have done is that i made a query function to determine if info is matched, and then i try to pull some infomation out from list item. this method works fine for printing these values to some labels on the form, however, it is not working for prepopulation, which happens in the page_load function.
in order to prepopulate some user information, i used query to search the sharepoint list. my question is how to search loggin user's info in the list. i used following testing query function. it works fine. however, it can only search specific text, cannot be changed according different user.

I have a databound dropdownlist and have a problem with the default value it selects.When I attempt to edit a record the dropdownlist shows the first value in the list rather than the current value. I want the dropdown list to display the current value.
I'm sure this is very simple but I'm very new to ASP.NET.
Basic #1: I need to add X amount of blank "rows" to my DataList before the SQL records are binded. This is on a 3 column Datalist so it is not literally a "Row" but more of an Item.Basic #2: How do I format the width / height for each Item so I have a uniformed layout that can be exported to PDF.Big Picture: I am creating a page filled with mailing addresses that will be printed out on Avery 5160 labels. Report writing is out of the question so I found this Datalist which does what I need but I have to beable to skip X amount of labels to preserv paper and I have to set height and width so it can be exported to PDF and then printed.
I want to get the valid emailID from the list.If I use the emailaddress from the address book of any mail account then the name of the user get appended with the emailID .eg:"Ayushi Soni" <asoni@[URL]>,.. and then copy these address to a textbox in an asp.net application.
Now I want to retrieve the actual EmailID from the list ignoring the name that is appended.Is there any utitliy that we can use to filter this out and validate the filtered email. I donot want to use regex for this.
