So I have been trying to follow serenarules posts about persistence layers, but I seem to be missing something.
The persistence layer is an architectural layer whose job is to provide an abstract interface to information storage mechanism(s).
This makes sense to me, but I am still having a hard time with this.
So in what cases is this necessary? When you are pulling similar data from multiple information sources?
I have a File Upload Control, so i click the 'Browse' button and when i select a file from the select file dialog, i want the file to be shown as a link below the File Upload Control( somewhat similar to gmail). This file should be seen such a way that it can be deleted, if i wanted to. And also i should be able to upload another file from the File Upload control.All these files should be uploaded to a location when i use a button click event in the end.
View 1 RepliesA relative newcomer to .net MVC2 and the entity framework, I am working on a project which requires a single web application, (C# .net 4), to connect to multiple different databases depending on the route of access, (ie subdomain).
No problem with this in principle and all the logic is written to transform the subdomain into an entity connection and pass this through to the Entity Model.
The problem comes with the fact that the different database whilst being largely similar in structure contain 3 or 4 unique tables bespoke to that instance.
To my mind there are two ways to solve this issue, neither of which i am sure will be possible.
1/ Use a separate entity model for each database. -Attempts down this route have through up conflicts where table/sp names are the same across differnt db's, or implicit conversion errors when I try and put the different models in different namespaces. or
2/ Overwrite the classes which refer to the changeable database objects based on the value of a base controller property.
My question is if either of theser routes can ever work in principle or if i should just give up on the EF and connect to the dtabases directlky using ADO. Perhaps there is another way to solve this problem i haven't thought of?
I am working on a project in which i have a master Gridview. It has a DetailsView and two GridViews as its children. I want to have the same master and child combination on two more pages in the application. On the first page i just want to change the select command of the master gridview and everything else remails the same. On the second page i want to change the master gridview to a dropdownlist with the same datasource and everything else remains the same.Can anyone please suggest me what would be the best way to go around it. Right now, all these three pages has its own set of codes and if i do any change to one of them then i have to do it in all three pages. I was looking at usercontrols but i think those won't work since i have do to slight modifications(as suggested above).

I am trying to populate the value(s) of a listbox that has multiple selections:
Assignment Preference:<br />
<asp:ListBox ID="assignmentPreferenceList" SelectionMode="Multiple" runat="server">
<asp:ListItem Value="">None</asp:ListItem>
<asp:ListItem Value="CONTRACTING">CONTRACTING</asp:ListItem>
<asp:ListItem Value="DIRECT HIRE">DIRECT HIRE</asp:ListItem>
<asp:ListItem Value="CONTRACTING-DIRECT HIRE">CONTRACTING-DIRECT HIRE</asp:ListItem>
</asp:ListBox>
I am using a datareader in code behind to "loop" through the values:
string sql4 = "Select * from assignmentPref where tID=" + (dr["id"].ToString());
SqlCommand comm4 = new SqlCommand(sql4, con3);
SqlDataReader dr4 = comm4.ExecuteReader();
while (dr4.Read())
{
assignmentPreferenceList.SelectedValue = (dr["assignmentPref"].ToString());
}
Works great with 1 assignment preference but with 2 or 3 it craps out.
I am trying to populate the values of multiple rows in single row in gridview using c sharp in rowdatabound section of code behind page like:
Col1 Col6
a 1
a 2
a 3
a 4
I have changed this to
Col1 Col6
a 1
2
3
4
Now I want to achieve this?
Col1 Col6
a 1 2 3 4
What wrong with the code below?
if (e.Row.Cells[0].Text == "" && e.Row.Cells[5].Text != "")
{
for (int a = 0; a<GridView1.Rows.Count; a++)
{
string s = GridView1.Rows[a].Cells[5].Text;
GridView1.Rows[e.Row.RowIndex - 1].Cells[5].Text += s;
}
}
What mistake I am making?
Cell[0] is Col1
Cell[5] is Col6
I am trying to retrieve multiple values from the session variable in which I stored the values as List. Here's the code I applied but this gives me only the lst value from the list in the output.
Array k= yourlist.ToArray();
for (Int32 i = 0; i < k.Length; i++)
{
Int32 x = Convert.ToInt32(k.GetValue(i));
SqlCommand cmd2 = new SqlCommand("select id,name from plugins where id =" + x, con);
SqlDataReader dr2 = cmd2.ExecuteReader();
if (dr2.HasRows)
{
while (dr.Read())
{
ListBox2.DataSource = dr2;
ListBox2.DataBind();
}
}
dr2.Close();
cmd2.Dispose();
}
I'm trying to dynamically populate a drop down box with fields from a SQL Server Database, but I'm having some issues. I am able to get it to work well with only one field, but I need to get display two fields in the ddl. I've seen that you can do it in the command statement, but I have two different data types and I think that causes it to throw an error: Conversion failed when converting the varchar value 'This is a Title' to data type int.
here is my code:

I have a parts table (ID, PartName, Category). I have an Engine table that has 10 columns to specify the 10 main parts that comprise the engine (EngineID, PartA_ID, PartB_ID, PartC_ID...).
I want to make only one trip to the DB to pull all the rows, then filter by category for each PartA, PartB, etc ddl. how to do this?
I have a list box that allows for multiple selections (holding down the control key) the selection quantity is basically unlimited, but realistically should never be more than 50 to 100 items from the listing of about 3000 items.
I need to collect the list of selected items from the drop down list and retrieve each of their full records from the item master and populate a gridview.
I am using a dataset control and I have 5 dropdown lists in which their content depends on what item is selected in each dropdown list.
I know I can populate the lists with 5 different queries taking the variables from each list but I am thinking there must be a better way.
Is there a way to populate each list with one query that takes the distinct items from each column returned without looping through the entire recordset?
I need to populate a dropdown list with users who match certain role criteria. For example, if I have the following roles: Manager, Employee, Supervisor I would like to populate the list with only the Manager and Employee roles. Some individuals have multiple roles and they should be excluded if they also have the Supervisor role as illustrated below:
Name: A , Role(s): Manager, Employee, Supervisor
Name: B, Role(s): Employee
Name: C, Role(s): Manager, Employee
The final list should only contain names B & C.
I can use Roles.GetUsersInRole("Employee") but I am not sure if this is efficient or not.

I could really use some building the SQL statement to select the choosen record data. I think I have the selection list worked out by populating an array but I am not clear on how to build the SQL query.

I have a one combobox and 3 textboxes and one sql datasource.
When I select the name in the textbox I want to show the values in the relevant textboxes. For instance, in the combobox when i select the Name of the employee the relevant information about this employee is shown in the 3 textboxes, i.e. age, cell #, extension.
I have a textbox and a gridview which is bound to a table what I want to achieve is a solution where lets say there are two records - e.g. "1. Book and 2. Red", i want a user to type in those words and the gridview shows the results as followed;
1. Book
2. Red
I have set up the sql data source and everything and my like operator is this.
LIKE '%' + @record + '%'
how can I solve this problem?

I'm building an mvc application and the customer asked to build a similar application that have almost the same controllers and views
of course I don't want to copy the same files to make new project , so How can I create the second project without using (Copy & Paste ) on code
of course it goes without saying that I have DAL and BLL so I'm not asking about those two layers , My question regarding the mvc interface layer only
if someone in here could write a script similar to the one on https://www.spalding-labs.com/Secure/Order.aspx . . . I have no idea how to or even where to start.
