Forms Data Controls :: Gridview Results By Date - Visual Studios Code Doesn't Work
May 27, 2010
I have a gridview that shows when something is check out. I would like to only show results from todays date and forward. I have done this in Expression Web but when I tried to use the same code in Visual Studios it doesn't work.
I have a gridview connected to my objectdatasource, i wrote a class for the database queries.Now when i do an update of record i get the id form the grid, when i click on delete i don't get the id, its 0.Is there an option to set the id? i can't find it in the gridview.
Im using File Upload Control in every row of a GridView.... Like tis
Name UploadFile textBox FileUpload TextBox FileUpload . . Submit
On Submit im first uploading all files present in the grid and then saving other values in database....No Problem when uploading Small Set of filesIf i browse more than 10(approx) files(i.e 10 files in 10 rows) and Submit... Internet Explorer-Page Cannot Be displayed Error occurs but no problem when uploading < 10(approx) files....
I have a GridView; one of the columns displays concatenated records from a tables. to extract the records that are going to be concatenated and put in this column, i have used: FOR XML path('') and it works just fine for displaying those records. the problem now is the whole gridview can not be sorted anymore and gives me a 404, document not found, error whenever i try to click the columns to sort. here is my select statement for my sql datasource select command:
SqlDataSource2.SelectCommand = "Select a1.*, keyword = substring( ( SELECT DISTINCT ', ' + keywordName FROM keywords JOIN key_mm_articles ON key_mm_articles.keywordID = keywords.keywordID WHERE key_mm_articles.articleID = a1.articleID FOR XML path(''), elements ),2,500) FROM articles a1 WHERE title LIKE '" & titles & "' Order By a1.articleID"
I'm using the code below to extract data from a gridview and populate it into textboxes for the days and two drop downs for Project and Category.
For some rows in the gridview everything but the category ddl populates correctly. If I click the row a second time the category ddl displays the correct category.
why I have to click twice for some rows? And how do I fix this?
I would like to know if there is a way to debug the gridview and work around the code that is behind it.Right now i'm getting an error when i try to modify a record with this control. So, if any of you guys know a way to get this done,
i have table that trace views of my page. every row has the id, date view (dd/mm/yyyy hh/mm/ss) how can i distinct the data into gridview (or something else) and display only the days (01/03/2011, 02/03/2001, 03/03/2011) and to sum the numbers of views (01/03/2011 1,290 views, 02/03/2011 867 views.....)
I have a datalist and want the results paged I have written a pager.ascx page and have an aspx and aspx.cs page to display the results. I have a stored procedure to pull the data out of the database and a class to talk between the stored procedure and presentation controls I have the pager being displayed when the results get over the limit I have set to 10 in the web.config file but when i click on the next link to display the next page of results it doesn't do anything. my aspx page is

I have recently come across a problem that hopefully someone may be able to help me with. I have checked the FAQs regarding Logins but am unable to find my problem. Basically I have been working on a simple web application using C# on VS2008. The application contains a private folder which contains web forms that can only be accessed after logging in as admin. When I run this application through Visual Studios it works fine and I am able to login and view the private database pages.
I am trying to do some code where a user will be able to upload a .JPG picture from the users computer. I have put the controls and also written the C# code wich in my eyes seems to be correct. What happens in the code is that the uploaded picture will replace the existing "TopHeader.JPG" picture.
However when I run the code after I have choosen a .JPG picture from the desktop on my computer. Nothing happens except of a postback of the page.
I wonder what I can be missing out in order to make this work. (I attach both the HTML code and the C# code, I will be happy to know what I could be missing out)
I inherited a .Net website project. Except for just 3 .aspx.cs files, pretty much every other file is a .aspx file.
I don't see any .csproj or any .sln files.
If I want to load up this website on my localhost, how would I go about doing it? Am I supposed to load up Visual Studios and "import" these *.aspx.cs and *.aspx file?
I already successfully set up the SQL Server database and updated the web.config with the appropriate credentials.
I've got in a gridview with two EditItemTemplate, which are dropdownlist. for the fisrt one I need autopostback because it's used in the second.So to bind the second dropdownlist, I'm useing the GridView1_ItemUpdating, but it doesn't work. It never goes into this funktion and so on updating the column with the second dropdownlist has Null values.What's wrong?That's my code:
I'm trying to run the performance wizard on an ASP.Net website. However, whenever I try to start it I get the following error.
"The website contains unexpected information or you do not have permission to access the metabase. You must be a member of the Administrators group on the local computer to access the IIS matabase. Therefore, you cannot create or open a local IIS website. If you have Read, Write, and Modify Permissions for the folder where the files are located, you can create a file system website that points to the folder in order to proceed"
I am an Administrator on my machine. Tried googling but came up with nothing. Anyone run it before and know how to deal with it?
