I am writing a table view for my ef model - I am not using the designer - I keep having issues with it. So I'm doing it the old fashion way of writing the code - All my tables and stored procs are working but now I added these two views and all is broken!In my SSDL I have
<edmx:StorageModels><Schema
Namespace="MyModel.Store"
Alias="Self" [code]....
I am getting the errors following - - Error 3 Error 2007: The Table 'ProgrammingCategory' specified as part of this MSL does not exist in MetadataWorkspace.
Error 4 Error 2063: At least one property must be mapped in the set mapping for 'ProgrammingCategories'.

Real simple one here. I'd like to create a table on my Page from a DataSet. It looks like I have it working properly, but what I'd like to do is interpret the columns, as well as be selective with which column to display.
[Code]....
I would like specific columns, by name or position doesnt matter.So if a column is = named column, then addcell and also, the data needs to be interpreted: If value of column = x then response.write("y")
In sum, I dont want all the columns, just specific ones, then I was to interpret whats in that cell, and write something.
[Code]....

In my application I am using the aspnetdb membership for authorizing users. I created a new table UserProfiles that will hold their profile information. The UserID is linked to aspnet_users UserID with a foreign key. One of the columns in the table represent CompanyID (int). I want to be able to restrict logged in users to only see records from their company based on the CompanyID. There can be more than one user with the same CompanyID to the UserID would not work. I can restrict their access by UsedID to only see records they created by using code behind:
[Code]....
and my select statement is:
[Code]....
How would be the best way to restrict the selected data to UserProfiles.CompanyID?

I am creating a html table from a list collection. I am able to create the table, but I am not able to group the related items and add into a single table.
[Code]....
I have 3 items in the list collection, in which Student Name is same for 2 items.
Now I am getting 3 tables. I want to group the student Name and get a single table for unique student name.
This is my list collection:
Student ID Student Name Mark1
1 John 25
2 Mac 22
3 John 24
I am getting 3 tables now, but i would like to group the student Name and then get a single table for John having his marks and another table for Mac.

I have a table that get populated via an external text file. I am not sure of the exact process as I'm relatively new to the company.
The table does not have a primary key as the entire table is dumped and re-loaded every quarter when there is a new text file.
Enter ASP.NET MVC. I need to display that table with checkboxes in a grid so the user can select some rows and send it back to the server. It sounds relatively easy, but I am really not sure what to put as the value for the checkboxes as I am pretty sure I'll need to use multiple columns to create a unique. Yep, I know, I know :).
OldTable
- Field1
- Field2
- Field3
...
- FieldN
The View
...
<input type="checkbox"
name="bunchOfStuff"
value"Field1Value,Field2Value,Field3Value"/>
...
Would something like this work? If I can create a key with a few fields, can I use those fields as the value in the checkbox? I realize my action will be a bit ugly as I'll have to split and parse each value in the array of values.

It is a dynamic menu control that supposed to be used on different sites.
However sometimes there is no "childitems" to show etc...
Usually I would use a simple repeater that creates an unordered list.... eg. <ul><li></li></ul> or something like that.
But I need more control due to some of the Items in the list needs to be checked for some values and if they have a specific value they should be a head node like:
<ul>A
<li>1</li>
<ul>B
<li>1</li>
</ul>
</ul>
What about using a literal on page? And in code-behind build a method that returns a string, something like menyString = <ul><li>something</li></ul>.
Honestly is this really a way to go when you creating a menu, I thinking of loading-time etc...??

I created a table dynamically with its row cell contain textbox. Now I need to show a hovermenuextender popup window on each rows textbox. I spend more time for this. But not getting till now.
This is my code for dynamically created table
private void GenerateTable(int colsCount, int rowsCount) {
string qry2 = "select lchannelname,ltransformdata from latestchannel where lenable=1";
DataTable dt = ob.getDetails(qry2);
dt.Columns.Add(new DataColumn("combined", System.Type.GetType("System.String"),
"lchannelname+ ' '+ltransformdata"));
//Create the Table and Add it to the Page
Table table = new Table(); table.ID = "Table1";
Page.Form.Controls.Add(table); int flag=0;
foreach (DataRow dr in dt.Rows) { TableRow row = new TableRow(); row.Width = 200;
TableCell cell = new TableCell(); TextBox tb = new TextBox();
tb.BorderColor = System.Drawing.Color.OliveDrab;
cell.BorderColor = System.Drawing.Color.OliveDrab;
cell.BorderWidth = 1; cell.Width = 200; tb.Width = 200;
// tb.ReadOnly = true; tb.Text = dr["combined"].ToString();
tb.ID =flag.ToString(); cell.Controls.Add(tb);
row.Cells.Add(cell); table.Rows.Add(row);
AjaxControlToolkit.HoverMenuExtender hrv = new AjaxControlToolkit.HoverMenuExtender(); hrv.TargetControlID = tb.ID;
Here I am confusing for which way is using for popup panel1
hrv.PopupControlID = Panel1.ID;
hrv.PopupPosition = AjaxControlToolkit.HoverMenuPopupPosition.Right;
Panel1.Controls.Add(hrv); flag++; } }
protected void Page_Load(object sender, EventArgs e) {
int numOfColumns = 1;
int numOfRows = ob.selectLatestEnableCount();
GenerateTable(numOfColumns, numOfRows); }
I want to popup this Panel1 on textbox through hovermenuextender
<asp:Panel ID="Panel1" runat="server" Height="50px" Width="125px">
<div style="border:1px outset white;padding:2px;">
<div><asp:ImageButton ID="ImageButton1" ImageUrl="~/images/close.png" runat="server" /> <asp:LinkButton ID="lnkButtonHide" runat="server" CommandName="Edit" Text="Hide Channel" ForeColor="olivedrab" OnClick="lnkButtonHide_Click1" /> </div>

I have a RSS feed i need to display in a table (its clothes from a webshop system). The images in the RSS vary in width and height and I want to make a table that shows them all. First off i would be happy just to show all of the items in 3 columns, but further down the road i need to be able to specify through a parameter the amount of columns in my table. I run into a problem showing the tr tag, and making it right, this is my Code so far:
<xsl:template match="item">
<xsl:choose>
<xsl:when test="position() mod 3 = 0 or position()=1">
<tr>
<td>
<xsl:value-of select="title"/>
</td>
</tr>
</xsl:when>
<xsl:otherwise>
<td>
<xsl:value-of select="title"/>
</td>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
In RSS all "item" tags are on the same level in the xml, and thus far i need only the title shows. Thr problem seems to be that i need to specify the start tag as well as the end tag of the tr element, and cant get all 3 elements into it, anyone know how to do this?

I am trying to create a TreeView nested structure with the use of self referencing table fields. Here is a simple example:
Category 1
Product 1
Toy 1
Toy 2
Product 2
Toy 3
Toy 4
more categories.. The database table has a single table called "Category". The ParentCategoryId points to the Category which is the parent. So, for the Category 1 the ParentCategoryId is null since it is parent. For Product 1 the ParentCategoryId is that of the Category 1 id and for Toy 1 the ParentCategoryId is that for the Product 1 id.
I am using the following code but it does not generate the TreeView (ASP.NET) successfully.
public void BuildTree(List<Category> categories, TreeNode treeNode)
{
if (treeNode == null) return;[code].....

I built a VB.Net 3.5 web form which has the following fields; Category, Title, Keywords and Code. I would like to use it to upload common code that I have come accross for easy access to it for future projects (code re-use). It will be stored in a SQL database. My question is how do I place the code (html, css, javascript, .net,...) that I enter into the code field of my webform (asp:Textbox) in my table (nText field) so that it displays in a webpage with all the appropriate line breaks, html tags, javascript... Should I enclose it in "<pre>" tags?

We have developed the Application using Visual Studio 2008, After publish we got the issue like After Submitting the Form the user can able to Move Backward and do the Refresh. This will again triggers the Submit Post Back and the Duplicate Record Created As Well.
This is happening for all the Web Forms. How to Avoid this ? I need a Generic Solution where i can implement that logic in Base Page then the rest of the Pages this functionality will be covered by default.
Moreover, Before Refresh We should also intimate user "Do you Want to Post the Same Data Again ?", if the user clicks Yes then it can allow the same record can be posted again.
How to do this ?? But i cannot disable the Browser Features like back, forward and Others. I have found many solutions in various web sites but it is also happening for the Validation Part Also...

I am creating a temp table and populating it's two columns manually and the rest of the table from the data returned by the stored procedure. When I added the first column called custno as @CustNumber, it allowed me to add it fine and the rest of the columns were filled by the stored procedure as expected. I then needed to add another column called RepeatCustomer the same way but it keeps saying:
Msg 207, Level 16, State 1 Invalid column name 'Repeatcustomer' So eventhough I have added Repeatcustomer column it's not seeing it. Any one has seen this error before or know what's wrong with this code. Note when I parse the query it's fine, it only fails upon the execution.

I have multiple tables that are all linked back to a central table with foreign keys. I want to be able to create a new record in table 2, but I'm having trouble because I don't know how to create a new instance of table 2's record while referencing the ID of the record it will be tied to.
EXAMPLE:
Database: Collection
Table: Collection Field 1: id Field 2: name
Table: Book Field 1: collectionId Field 2: id Field 3: name
Now, I don't want to be able to create a book without setting it's collectionID, but I can't figure out how this should be divided in the controllers/views.
Should Book have a controller separate from Collection, or should the Collection controller have a createBook method, separate from it's own create method?
I want to call the createBook method (from it's own controller, or the Collection controller) from the Collection Details view.
When I invoke the create method of Book, how do I create a new Book that is instantiated with the collectionId set from the details view of the Collection item that was listed in the details view?
I should point out, I'm using the entity framework for my model, and I'm definitely new to this.
