Forms Data Controls :: Load 'item' Data From Linked Table?
Feb 2, 2011
I have come from MS Access and am working through a couple of textbooks on ASP.NET 4. I am using the Gridview control connected to an SQL data source control.
As an exercise I am converting my simpliest MS Access page which is simple a form to request a new stock item in our engineering stores. I have a normalised table called [stock_requests] and part of this is a field calle [failure_mode]. This field is an integer and there is another table listing the possible values for this field.
This other table is called [failure_modes] and has two field:
[id] < the primary key
[mode] < the text to be displayed
In my main table [stock_requests] in the field [failure_mode] I store the [id] from the [failure_modes] table for the applicable record in the [failure_modes] table. So for example if someone wanted to select "Catastrophic" as the failure mode the [stock_requests].[failure_mode] field would be 1; if the user selected "Gradual" as the failure mode the [stock_requests].[failure_mode] field would be 2 etc.
Now, the gridview wants to display "1" or "2" but I want to display "gradual" or "catastrophic" without using views and all the headaches that brings. I have managed to sort out editting by using a templated field where I have a drop down list in this cell and I databind to a second SQL data source (imaginatively called SqlDataSource2).
what is the best method for displaying the text 'Catastophic' or 'Gradual' etc. when in normal mode (view mode)? Is it another templated field and what is the basic approach I should use? I reckon I should be able to work it out once someone points me in the right direction.

I am binding same data Table to Combo box and List Box on the WindowsForm Load.
When I select a value in Combo box automatically that value is also getting selected in List Box and same thing when I select a value in List Box that value is also getting selected in Combo Box.
Selection should be only for that particular control, how can I achieve this ?

I have a "report" the users can run it basically creates a simple gridview. In the gridview the user can click on a claim ID. The claim id is then passed via url querystring to a claim management page. The claim management page uses a listview to display the various claims and allow users to edit them. I want to use the claim id passed in the url to locate the listview row to open in edit mode, so the user can make changes / alterations to the claim.

I have built a set of custom business objects that I have successfully bound to the GridView and DetailsView controls using the ObjectDataSource. I have been able to provide insert/update/delete functionality and all is working as expected. However, I am trying to wrap this functionality into a custom user control that allows the consumer to specify a table name and a list of column names and have it build this functionality on the fly without regard to the table structure (ie...available columns). I have been able to successfully get the GridView and DetailView to build the columns from code behind and I had all the CRUD working while using 2 panels to show/hide the GridView and DetailsView controls, but I wanted to add some AJAX ability to the control using Matt Berseth's modal popup example to make the interface slicker. The problem I am having is that the EditItemTemplate for the DetailsView control has to be specified in the code behind (because of the flexibile nature of the columns) and I can't figure out how to bind the data from code (rather than having the columns defined and bound in the markup). For all intensive purposes, I am trying to find the code behind counterpart to the following code snippet that binds the data to the textbox:

Here's a short explanation of my asp.net project.
1) the default page loads, it will read the Windows Login of the user opening the page.
2) I'll check if this login exists in a table stored on the webserver.
In this Access Database, there's a 2nd linked table, pointing to another access table on a network location. Now, I want to read data from this linked table. However, at this moment I receive an error:
"The Microsoft Jet database engine cannot open the file '\<ip><shared-folder>statistics.mdb'. It is already opened exclusively by another user, or you need permission to view its data".
Some extra info:
- The network folder has read and write permissions for everyone
- the user and group permissions on both access files are set to read/modify/administer for the Admin user (on the tables I want to read from)
- IIS authentication on the server is set to "Windows Authentication" (this is needed so I can read the Windows Login from the user). All other authentication modes are disables (like anonymous, ...)
- When the error occurs, no other program or process has access to the statistics.mdb (so, it can't be locked by someone else)
- the web.config files access connection string looks like:
<add name="AccessConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\<IP><shared-folder>statistics.mdb;User Id=admin; Password=;" />
Like I said before, in this statistics.mdb file, there are 2 tables. One normal table, and another linked table (pointing to a network location)
Searching for solutions, I discovered the following:
- if I don't use linked tables, everything works fine (however, I have to use this linked table)
- even if I connect directly to the table in the network I receive the error. So, I'm pretty sure I don't have sufficient rights to read from this table.
I read that not the Admin user is opening the file, but actually a user called ASP.NET. This user doesn't have the correct rights to do this. However, I'm not sure if this is true.

I have a site where users can save images together with a couple of info fields about the image. The images are stored as binary data in the same table as the rest of the image info. So far pretty standard.
Now, the users should be able to upload a document, describing the image in more detail, along with the rest of the image and its' info. Size ~2MB per document.
My question is: Should I store this document (binary data) in the same table as the rest of the images or should I create a new table holding only the documents. There would of course be an id reference in the image table to the document in the document table.
I have a search function joining a couple of tables, including the image table, when searching for images. I need to know if there's a difference in efficiency between these two solutions. I always fetch the document data separately but if I don't win anything in having the documents in a separate table I'll just put it with the rest of the image info.
I'm asking this since I don't really know how SQL Server handle tables when joing and searching in them.
I have about 10´000 users with a maximum of 10 images per user. (ASP.NET - SQL Server) (I'm not asking if I should store documents in the database, but how ;)
Edit
Example 1:
columns in imageTable - id, title, dateAdded, image (binary data), document (binary data)
Searching for items from a specific user I would join the userTable and the imageTable and select title where image id equals user id.
So, will there be any difference in the performance if the document is in the imageTable or in an own table?

I'd like for where there is a 1 for it to display a checked radio button, and where there is a 0 for it to be unchecked. This can then be edited by clicking the radio in another column where necessary.

I have a form free user feilds, some drop down which are populated by a database data and a button. I want to create a new line in a table when the user clicks on the button. the values for this new line will come from the Values (not visible content) of the drop box, the content of the text feild, the user ID that I should get from the connection and the current date... ie, I want do do a INSERT INTO table (userid, dropdown, text, date) values (how do I get the user ID from the session?, how do I get the value from the drop down?, how do I get the text from the text box?, how do I get the current date?)

I have 2 columns (name and address) in a gridview which are defined as linked buttons. Now when i click on a record in the first row (name) i am able to pass that value (selected name) to another page with rowcommand. Now i am trying to click on the second row (address) on a record but am not able to pass that value to the second page. Don't actually know how to define this in the code below. The first row (name) has to redirect to one page (this what i have already accomplished) and the second row (address) has to redirect to another page
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:LinkButton ID="LnkBtnName" runat="server" CommandArgument='<%# Container.DataItem("Name") %>' Text='<%# Eval("Name") %>' CommandName="go" >LinkButton</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Address">
<ItemTemplate>
<asp:LinkButton ID="LnkBtnAddress" runat="server" CommandArgument='<%# Container.DataItem("Address") %>' Text='<%# Eval("Address") %>' CommandName="go" >LinkButton</asp:LinkButton>

Protected Sub GridView_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView.RowCommand
Dim strName As String = CType(e.CommandArgument, String)
Response.Redirect(String.Format("Test.aspx?id={0}", strName, False))

I use a ItemDataBound for a repeater.But i use 2 kinds of linq querys to bind it.Some of them has a MerkID, and some doesnt have this item.So its easy i need to do this:
if(e.Item.DataItem.Contains("MerkID"))
{
//Code for linq query 1
} [code]...
So of course the if selection doesnt work, but how can i do that? I already tryed this:
DataRowView drv = (DataRowView)e.Item.DataItem; if (drv.Row.Table.Columns.Contains("MerkID"))
But that doenst work because he cant convert it to a datarowview because its a linq class.So what to do? Right now i use a try and catch, but there are better solutions i guess...

I have a repeater control:
<asp:Repeater ID="rep" DataSourceID="XMLDSCompare" runat="server">
<ItemTemplate>
<h4><%# XPath("title")%></h4>
</ItemTemplate>
</asp:Repeater>
Now if its the first item in the total resultset, I want to add <div> to ItemTemplate control, if its the 2nd item, I want to add </div>
So output would be (not including table tags generated by repeater control):
<div>
title 1
title 2
</div>
<div>
title 3
title 4
</div>
<div>
title 5
title 6
</div>
How would I do this in the ItemDataBound event of repeater control?

I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?

I'm binding my object data source to a method that returns a list of ints (List<int>).
The object data source is being used by a DataList.
<asp:ObjectDataSource ID="objectDataSourceYears" runat="server" EnableCaching="true" CacheDuration="Infinite"
SelectMethod="GetYearsUnderArticles"
TypeName="Project.DAL.Services.UmbracoService"></asp:ObjectDataSource>
My question is:
How do i display the values of the ints. Normally, I would use DataBinder.Eval(Container.DataItem, "FieldName"), but what in this case, since the object itself is the value?
