Is there a way to create a contact form that takes the name. address and other info for the master record; Then, somehow, on the same page, allow the user to enter multiple contact info as chid records (i.e. phone, email, etc.)
All this using the Objec DataSource or SQL DataSource (which ever is easy) and doesn't require writing too much code.
I have a table that needs sorting by its hierarchial structure of parent-child.
An example of my table is below

As you can see above, my table structure follows this pattern
[Code]....
My overall aim is to have the sql order the table for me, and by using this new "depth" column, I will be able to indent by categories in the menu on the front end, you have probably seen this before, but all the tutorials I have read dont really explain it very well, or assume you are sql savvy.
I have a table that have LibraryID and LibraryParentID.
LibraryID int Unchecked
Name varchar(50) Checked
Description varchar(200) Checked
LibraryLevel int Checked
LibraryParentID int Checked
LibraryTypeID int Unchecked
I want to write a sql to delete the currrent select parent and well as all child record, how can I do that?
I have two nested UpdatePanle and a button and an editor in parent panel and a GridView in child panel.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Button ID="btn_UsersList" runat="server" onclick="btn_UsersList_Click"
Text="users" />
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView_UsersList" runat="server">
</asp:GridView>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btn_UsersList" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
<FCKeditorV2:FCKeditor ID="FCKeditor_Message" runat="server"
BasePath="~/fckeditor/"></FCKeditorV2:FCKeditor>
</ContentTemplate>
</asp:UpdatePanel>
I'd like to update the child panel when click button but don't update the parent UpdatePanel.
I am just getting started with entity framework with asp.net 3.5 using VS 2008
There are two tables, Categories & Subcategories:
Category table: CID, CategoryName Sub Category table: SID, CID, SubCategoryName I would like to get SID, CID, CategoryName, SubCategoryName in the gridview. Just as we write a select statement i.eSelect a.sid, b.cid, b.categoryname, b.subcategoryname from subcategories a inner join categories b on a.cid=b.cid & put the same in a gridview.
I was trying for the whole day & couldnt get atleast one url that would teach how to do it.
I have Parent(order)and child(Orderdetail) object how to insert through dataadapter.Update() method in single shot.
View 1 Replieshow to insert parent/child data to the database. I have a form with two 'dropdown' lists and two text boxes and a 'Comment' text area. I need to save some fieldsto the Parent table and some fields into the child table.
View 2 Replieseasiest way to create/update a parent and child record at the same time (like customer with multiple addresses) with least or no code as possible? Both Web Forms and in MVC.
View 1 RepliesThis is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)
If IsDate(pasDate) Then
Try
If pasDate <= System.DateTime.MinValue Then
Return Nothing
Else
Return CType(pasDate, DateTime)
End If
Catch ex As NullReferenceException
Return Nothing
End Try
Else
Return Nothing
End If
End Function
So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".
I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.
IS THERE A BETTER WAY TO UPDATE/INSERT TIME FIELDS.

I'm trying to update the data in the parent table that is referenced in the child table from the child's view in Asp.net.
I mapped the tables using Fluent Nhibernate.
In the child table, the mapping looks like this:

how can you update the parent and set the child not to update?
I have a parent gridview which has a child gridview in the itemsTemplate. Both are binded to different SqlDataSources. I can successfully update and delete rows in the child gridview. After updating in the child gridview, some related data in the parent gridview are not updated automatically. So i have placed ParentGridview.Databind() in the rowupdated event of child gridview. But it doesnt look working.
How can i accomplish this?
This is my first attempt at updating a database using LINQtoSQL. At least, it's my first if you don't count the tutorials I've followed. Unfortunately, The tutorials that I have found don't offer much more than updating a single table. I'm attempting to update a DB Model that's a bit more complex.
I have a Stream table:
[Code]....
I am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:
[Code]....
However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.
i am trying to delete using Gridview from child first and check if there is no child to delete in parent table i am using sql datasource in the delete tab in sql datasource i put DELETE FROM table1 WHERE (IDtable = @IDtable) IF (SELECT count(*) FROM table1 WHERE parent_dtl_id = 66) =0
BEGIN delete from parent_dtl where order_dtl_id= 66 END
i deleted all items,deleting from 2 tables child and parent was successfully on the last row from gridview but i have this error on my page on the last delete Specified argument was out of the range of valid values. Parameter name: value
On DBML I have two entities as Parent, Child. I am trying to assign Child class properites in a Parent.

I am getting the following Error:

Simple and blunt: my cascading dropdownlists clear when a postback occurs. Does anyone know a quick way around that?For more information, read on...
I have 5 dropdown lists that define a training class location and line of business: Site, Parent Client, Client, Program, Project I'm trying to build cascading dropdownlists that can work from any direction (i.e. select a site and all other lists are filtered by site...select a project and all other dropdown lists are filtered by project). I've built the SQL Select statement behind the lists that filters (accurately).
I have a gridview1 which is the parent gridview and I want to insert another gridview2 which is child gridview inside every row of parent gridview This is the code in the .aspx
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:GridView ID="gridView2" runat="server">
</asp:GridView>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
This is the code that I have added inside the RowDataBound Event and i'm just binding the gridview2 with the arraylist which is filtered data depending upon the contents of each row's invoice number.................
I am trying to use the TableApapterManager.UpdateAll to insert values to master and child table. I had set the relation to cascade for update in the dataset and the HierarchicalUpdate to true. But stil when I run TableApapterManager.UpdateAll(dataset), I get a foriegn key violation error. Following is the code I used:
int ID;
DAL.Datasets.dsMembers.MembersRow rwMem = m_dsMembers.Members.NewMembersRow();
rwMem.u_name = mem.Name;
m_dsMembers.Members.AddMembersRow(rwMem);
DAL.Datasets.dsMembers.MemPhonesRow rwmemphn = null;
rwmemphn = m_dsMembers.MemPhones.NewMemPhonesRow();
rwmemphn.u_memberid = ID;
rwmemphn.u_phn = "test";
m_dsMembers.MemPhones.AddMemPhonesRow(rwmemphn);
m_adpMgr.UpdateAll(m_dsMembers);
return ID;
The error I get is "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_MemPhones_Members". The conflict occurred in database "Family", table "dbo.Members", column 'i_memeberid'.
The statement has been terminated."
how do i insert date and time together ? what is the format for this. i tried like this but its not working.
string startDtime = TextFromDate.Text + " " + Stime;
sql_comm.Parameters.AddWithValue("@StartDate",
DateTime.Parse(startDtime));
is this the right way ? dd/mm/yyy +" "+ 00:00
or i need to make a string that contain this : dd/mm/yyy00:00
its not writing any eror it just do nothing .
a FormView that is linked to SqlDataSource1a Repeater control (inside the formview) that is linked to SqlDataSource2 Thus representing a simple "1 to many" or "parent/child" relationship in the database!
SqlDataSource1 is simple in that it just retrieves a straight set of records from a table and they are displayed back in the FormView (nothing special happening there).
SqlDataSource2 has parameters that filter the contents of the repeater based on the record that is shown in the Formview. This would normally be simple enough to set up by setting the parameter to the formview.selectedvalue property.
HOWEVER - THE PROBLEM ARISES...
The formview has multiple DataKeyNames because the table that the SqlDataSource1 links to has a compound key. So to filter the Repeater correctly SqlDataSource2 needs to map 3 parameters to 3 data key values in the formview.
I've tried setting the SqlDataSource2 parameters to:
<SelectParameters>
<asp:ControlParameter ControlID="FormView1" Name="Parameter1" PropertyName="DataKey(0)" />
<asp:ControlParameter ControlID="FormView1" Name="Parameter2" PropertyName="DataKey(1)" />
<asp:ControlParameter ControlID="FormView1" Name="Parameter3" PropertyName="DataKey(2)" />
</SelectParameters>
but it doesn't seem to like that approach. I'm expecting the answer is something similar .
I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
Sample Code:

I'm trying to combine a date and time from separate variables in my asp.net insert sql. pointers? I'm getting the following error

restrict user not to insert data in a booked time slot,suppose User reserved an item say below dates, now how to restrict other users to reserve that item at the below time.
date1 date2
2010-06-30 09:00:00.000 2010-06-30 12:00:00.000
how to restrict below cases:
(A,B are other dates entered by other user)
date1 A B date2
A date1 B date2
date1 A date2 B
A date1 date2 B
hence AB must be less than Date1,Date2 or greaterthan Date1,Date2
