Data Controls :: Display Only Recent Record In GridView Using Sql Data Source
May 7, 2015
I have a drop down which gets data from database.I want to show not all entries but the very last one entered by employee. What do I have to add to the sql script to get me very last entry and hide the rest.this is my Sql data source:
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CompanyInfoEventsConnectionString %>"
SelectCommand="SELECT [ID], [NameOne] FROM [Gpi_DayOff] ORDER BY [ID] DESC">
</asp:SqlDataSource>
I have been researching this for quite a while. I'm a beginner ASP.NET programmer using Visual Web Developer.
I create a database and then allow users to add data to it. I also display the data on a repeater. At the moment the data is being displayed from the oldest data to the newest data. I want to displau the data from new to old. I want to sort and display the data according to the items' IDs.
e.g.
LATEST MEMBERS ID:10 Name: Donnie Dollie ID:9 Name: Liam Stan ID:8 Name: Frank Fro Older members>>
How to display empty GridView to insert new record if no data retreived for some record on the result from data table?Actually i am trying to give a user an option to add recrod from Gridview. On result of some query it is perfectly displaying data and a footer row with the insertion textbox but when there is no data in the gridview it is not displaying. It should display with footer having insert textbox.
I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?
I have a dropdown list with sessions: Summer, fall, spring, summer Interim.
And also have a gridview to display hours of those sessions. When chose session from dropdown it displays the data related to gridview.
Gridview has the 'Edit' option to edit hours for each sessions:
[Code]....
When I edit let say spring and update the field it redirects me to main page but everytime it selects the data from summer).
What I want is? If choose Fall from dropdown and make edit(in editpage.aspx?id=..) and update the data, then it should redirect to main page but choose the Fall from the dropdown (Not summer)
I have one repeater and one gridview, i want to bind my repeater when link button is clicked which is inside repeater, i user itemCommand but its not working....

I am using paging to my gridview (pagesize=4) . now i am in (X) page and i want to get (X+1) page top record or (X-1)page bottom record , how i can get .
I want users to select a record in the GridView and then have that record open up in the Detailsview. How would I go about getting these two tools to communicate?

This is my code and i am only able to edit the one data under the category school.But what i nd is to edit the other categories like the name,email...etc..how do i modify my code in the update command.Another thing is to delete the data how do i do that?
In the stord procedure below. I am retreiving all the records for that 1 deal. What I want is to retrieve the most recent record hence the one with the most recent in the AddedDate field.
How can I accomplish this?
( @DealID int) AS SET NOCOUNT ON SELECT deals_Comments.CommentID, deals_Comments.AddedDate, deals_Comments.UserID, deals_Comments.AddedByEmail, deals_Comments.AddedByIP, deals_Comments.DealID, deals_Comments.Body, deals_Comments.SBody, ROW_NUMBER() OVER (ORDER BY deals_Comments.AddedDate DESC) AS RowNum FROM deals_Comments WHERE deals_Comments.DealID = @DealID
Last night I started working on an NHibernate provider. I'm creating a criteria that several records will match, however I only want to return the most recent record (the record with the largest Id). I thought UniqueResult() would do this it cannot be used if a list would be returned otherwise.
I could theoretically select the full list and then return the desired record, but I believe there is a better way.
My question is about limiting the record display. I do not prefer to use paging. For example, I have 100 records in database. I only want to display the best 10 record. Im using Visual Web Developer 2010.
The link was close in answering my question but again, I prefer not to have paging or sorting in the form view or the control.
I have a gridview with daatsource from MembershipUserCollection. When my collection doesn't contain any records the gridview just disappears. I want to display the empty gridview indicating no records exist rather than the grid just become invisible.
I have a gridview and I have an edit template for one control. I have a drop down box in this edit template so that you can select a value from it and then when you hit 'Update' the value from the drop down box is committed to the updated record. Unfortunately when I do hit the update button I get a fault that the "Status" field cannot be null.
Here is the code that picks the value from the drop down value and assigns it to the new values list:
I'm using a GridView to output some information regarding an account, specifically account balances. Problem is, if there is no balance linked to the account, I need for the grid to simply display 0 for each column. EmptyDataText isn't sufficient as the columns still need to be listed, but just have the value 0.
After researching it seems like I will need to add a dummy row to the gridview if it is empty, but how do I do this using C# and ASP? Quick note as well, not sure if it's relevant but the grid will only ever contain one row.
i am working on a website,As i am new to coding i got a problem in it. It was,I hav a gridview in which i am adding the details about a college, and in that i had a buton ("btnReservation") on clicking it another grid will be appeared in which, i hav to enter the reservation details so, till this step it is working fine, but if i enter one college details and clicking on the btnReservetion the grid is being dispalyed and i am able to enter and save the data, But if i enter the details of another college and clicking on the btnReservation, the rows which i hav already entered in the Reservation grid for the previous record are not being Refreshed and are remaining the same,So now i hav to make the gridview datasource null.
