I have a master document which is composed of other document types (some are required and some are not). While the master document's status is "Draft" I need to ignore all not nullable constraints (because the writer may decide to work on one of the children
documents that is not required and save as draft).
The closest solution I found for this problem is check constraints but I have not yet to see an example of this in check contraint and I'm not even sure if this is possible. Has anyone implemented a similar solution with check constraints (or any other methods)?
am using vs.net 2005 with c# i want to create the dynamic textboxes and retrieve the value of them.
i have the following page :
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="testDynamicTextBox.aspx.cs" Inherits="testDynamicTextBox" %>

Here when i click on "Add More" button one more text box should be inserted to the form (the maximum limit for textboxes is 10) and when i clicks on the "Submit" button i want to display the content (textvalue) of the text boxes(all the text boxes).
I am not understanding why I am getting the following error (also mentioned in the subject line). I have written the following function in SQL Server 2005:
CREATE FUNCTION dbo.GetCandateID()
RETURNS INT
AS
BEGIN
declare @candidate_id int
SELECT @candidate_id = max(c.candidate_id) from dbo.candidates c
if(@candidate_id is null)
set @candidate_id = 1001
else
set @candidate_id = @candidate_id + 1
return @candidate_id
END
The function compiled properly. I have used the above function like below in the query:
select dbo.GetCandidateID()
I am getting the following error: Cannot find either column "dbo" or the user-defined function or aggregate "dbo.GetCandidateID", or the name is ambiguous

View 2 Repliesa pure html table will be generated on the client side. (using jQuery to add dynamic new rows to the table when the user clicks a button).
These rows contain textboxes, dropdownlists, checkboxes and other input controls.
When the user clicks a button, a PostBack is triggered in which I need to access this data from the table on the server side, validate it (yes all rows at once) and perform other actions on it.
I'm able to perform the client side and access the table data on server side by adding runat="server" to the table tag. However, I only see the initial table rows (not the ones added through JavaScript) and I have troubles retrieving the different inputs from the rows.

I have a form in a page and a panel inside the form.The panel gets loaded with dynamic controls like radio button and text boxes.
User is allowed to choose any radio option and enter any value in the textbox beside it and then goes for submit button to move to next stage.
Problem Descritopn:
I load the controls in the panel based on the index of a combo control on the same form.it is done in selectedIndexChanged - This is working fine.
When i go for the submit button and ask for the textbox control, it says "object reference not set to instance of object", denoting that instance is not available. Moreover the panel control list gets empty automatically.

I want to retrieve the value for the id column for each row in a gridview. I dont want this in a gridview rowdatabound function or anyhting, but an external function.
Normally I would do something like:
Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "id"))
in a rowdatabound event. I now want this from another function, something like:
Private Sub GetGridviewIds()
'THIS DOESNT WORK!
Dim ttypeId As Integer = gvTickettypes.Rows(i).DataItem("id")
End Sub
So how can I access the data value in a gridview row?
I have a Timestamp column in my Table. I want to read the date time value and display in UI.
In Linq the Timestamp column is represented as System.Data.Linq.Binary.
I dont know how to retirve date time value in "MM-dd-YYYY" format from this Linq.Binary
- Why I am using Timestamp?.
I want to perform some operations based on the last modified date time of the particular row. Since I am using TimeStamp column in my Table as version column, It will contain the last modified date details, So i want to read the date time value from this time stamp column to do some other operations.
I am creating dynamic controls... i.e. ddl
DropDownList ddl = new DropDownList();
ddl.DataSource = data;
ddl.ID = id;
ddl.DataValueField = "Key";
ddl.DataTextField = "Value";
ddl.DataBind();
PlaceHolder1.Controls.Add(ddl);
Loading the controls to the placeholder.
Selecting a value and clicking the button, doing postback, I want to capture the value selected in the ddl. I was using "FindControl method" but it is not working, I guess because the controls are created dynamically and will not show due to stateless HTTP.
How else can I capture the values? Is there away?
