I have Create and Edit forms for Categories. Columns are Id, CategoryName, Order, CreatedOn. On Create form I save the values for all but on Edit form I need to change only CategoryName. Below is the code. Problem is that on Edit form only CategoryName field exists which on submit button is passed to Edit Action. Whenever I update Order and CreatedOn becomes null because the values are not returned from form. Someone tell me any good approach how to Updated selected values in EF. Below is code.
Making multiple Get calls. Form is saving fine but I don't like the approach. Need clean approach. Anyone got better solution to thiis?

how to add a prefix value with existing value while updating a column in sql??
View 4 RepliesI have a DataGrid with a TemplateColumn containing an asp:DropDownList and a BoundColumn. I'd like to have a VB.NET handler for when the selected item in the DropDownList changes. I'd like this handler to also update the value in the BoundColumn with the value of the newly selected item in the DropDownList.
Can someone point me to some resources I can examine to learn how to do this?
If the handler for the selection changing can give me the value of the NEWLY selected item, it should just be a matter of accessing the cell for my BoundColumn in the same row and writing to it. I do not know the syntax to achieve this.
I'm trying to implement row editing on a gridview using a SQLDataSource, the updating works fine for all values in the row except for on value, Clock Reset Time. I have tried all sorts, tried converting to template fields, tried reordering columns, changing update query etc. I just cannot get the gridview to update the Clock Reset Time. here is the code.

I am using a gridview to show data in a formview on a ModalPopup. in the modal I have a Close button and Delete button. The delete button has a click even that is supposed to updated a column in the table, but it doesn't and I can't figure out why.
[Code]....
The varTransactionID variable gets value upon click of the gridview linkbutton so the value should be there. As you can see I have tried 2 ways of adding the Parameter Value of @TransactionID, they both do not work. The column never gets updated. [explanation] The reason why I do not just delete the record is that as Web Admin I want to still be able to view what changes are made to accounts so I can adjust the site to make things more user friendly, the user may not see the "deleted" record, but I still can.
I have a gridview in which update and delete is enabled.
I have the following fields in database table, which is binded to the grid view through sql datasource.
ID,Firstname,Lastname,Add,City,modifieddate. Here ID is primary key.
1. When edit and delete is enabled in the grid. The ID column is showing in the grid,which i don't want to show. But without that ID column the grid is not able to update and delete. Plz tel me how to update and delete without ID column in grid.
2. When ever any update is happen in the grid, the modifieddate should get updated. Here the date is not datetime.now , i need to use my own system date and time. Coz my server and system time has some difference.
I have use the following javascript to get system date and time, which is working fine. This date should be get and update in the modified column.
function displayTime() {
var m_names = new Array("Jan", "Feb", "Mar",
"Apr", "May", "Jun", "Jul", "Aug", "Sep",
"Oct", "Nov", "Dec");
var localTime = new Date();
var year = localTime.getYear();
var month = localTime.getMonth() + 1;
var date = localTime.getDate();
var hours = localTime.getHours();
var minutes = localTime.getMinutes();
var seconds = localTime.getSeconds();
var div = document.getElementById("TextBox1");
div.innerText = date + "-" + m_names[month] + "-" + year;
}
I have been struggling with this problem for a long time. Does anyone have any clue about this problem? I created a gridview and set the allowsorting to true. This gridview has four columns: Name, Position, StartDate, and EndDate. I want the gridview to be sorted on the EndDate.
Inside of the save event, I called the BindGrid() function to rebind the datasource to the gridview. The changes will shown immediately, but the problem is that the records are not sorting on EndDate. I have to refresh the page manually to get the view sorted.

In trying to improve 'user experience' with a GridView, I have an administrative application where a GridView is displaying records from a SQL table. One of the columns is a bit column, and is displayed as a checkbox in the GridView. I want the user to be able to simply check or uncheck the box while viewing the GridView, and the value in that column for that record is immediately updated. So I set AutoPostBack="true" on the CheckBox in the GridView's Template Field.
But tests are indicating that the column value is not actually getting changed, even though the page appears to post back and displays the newly checked (or unchecked) checkbox correctly. But if I check the SQL table directly the column's value has not changed.

I have a SQL Server 2005 database which is queried by a web service which is called by an aspx page.
I inherited a messy and inefficient project, and I was working on cleaning up a GridView by making it dynamic and by having consistent field names in the database when I started getting an error of - Sys.WebForms.PageRequestManagerServerErrorException: Invalid column name: 'ASSIGNED_TO'
Assigned_to does not exist in the database, in the web service, or in the website solutions in any place. It was the name of one of the fields in one table, which I changed to USERID so that either of two datasets would fit into a Gridview (all other fields were the same). I then replaced all references of ASSIGNED_TO with USERID, which is when the issues began. The first of the two queries below causes the exception to be thrown, but the second one does not. I have tested both with the WCF Client and with a query within SQL Server to verify that they do work, so the issue has to be on the website side.

[Code]....
Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
Heres the situation: I need update a column from my table (T1) from two other columns in a different table (T2).
My constraints are:
That I have to match the first 4 letters of a column in T2 to one column in T1 I have to identify that the first letter in a column in T1 corresponds to one letter in the middle of a string in a column in T2 For instance:
My Table (T1):
Order Type Combined
Place
0090 0001 YYXX 1YY
0091 1001 YYXX YYY
0092 1002 XXXX 2XX
Table 2 (T2):
Order Value
00900001YY XX
00911001YY XX
00921002XX XX
The Combined column in T1 is what i'm trying to complete. The T1.Place column contains the first character that I want to check for.
If it's a "1" then I want to make sure the 5th letter in T2.Order is a "0" If its a "Y" then I want to look for a "1001" If its a "2" then I want to make sure the 8th letter is a "2" in T2.Order
If all that matches then I was the last two letters in T2.Order + T2.Value to be combined and put into the appropiate spot in T1.Combined

I know it's a little complex, but i'm really stuck on it and any help would be greatly appreciated.
I am facing a problem here. I have a column where the value is equivalent to my identity column's value. For an example, I have a column A store is "ABC0001" and the 0001 is came from a column called Column B which identity on. when a new record inserted and Column B is next identity number and Column A value is "ABC" and add number from Column B.

View 5 RepliesI'm trying to figure out how add extra logic to this derived column expression:
LEN(TRIM(pup_date)) == 0 ? NULL(DT_DATE) : ((DT_DATE)(SUBSTRING(pup_date,5,2) + "-" + SUBSTRING(pup_date,7,2) + "-" + SUBSTRING(pup_date,1,4)))
If there's a 0 in the field the code inserts a null. Otherwise it inserts a date. How can I change this to insert a NULL if a question mark "?" appears in the column?
This is what I tied using the OR operator but it's not working:
LEN(TRIM(pup_date)) == 0 || LEN(TRIM(pup_date)) == "?" ? NULL(DT_DATE) : ((DT_DATE)(SUBSTRING(pup_date,5,2) + "-" + SUBSTRING(pup_date,7,2) + "-" + SUBSTRING(pup_date,1,4)))

I have a number of manually written scripts (.sql) for tables, views and stored procedures that are used from an ASP.NET application. These scripts drop the object and recreates them. I need a way to update the database when the scripts change without deleting the object. For example, when a column is added to an existing table that has rows in it, I would need to update this table with this extra column without losing the rows.
I need a way to "update" the database on a single click (I can hook up the changes using a batch file). Does Visual Studio support this kind of functionality?
I would like get some hints reagding my application. Acctually I have a text file which is on Server and updated daily. After I parsed my text file, I would like to update my database according to the text file's data. I'm wondering how I can sepcify the input to SqlCommand so that my table should have the text file's input and then update the values.

I have a ddl that they select a last name and it populates first name, last name and spouse in a formview. This all works. There are a couple of other textboxes that need to be filled out. When I try and run an update into the volunteer table I get no errors and page shows the meber was updated. However, when I go into the volunteer table, there is no data.

I don't understand why it is not updating into the table. Especially since I am getting no errors.

I'm building a browers-based game that will need to constantly be updating EVERYONE'S accounts regularly; what is the best way to go about doing this? Creating a process that runs every time someone goes to a page on my site slows down the load time immensely. Do I need to create a windows scheduled task that calls this/these process(es)? It will need to constantly run.
