Build A Control That Work Like An Access Table?
Jan 8, 2010
What is the best way for me to build a control that will kinda work like an Access table in ASP.NET?
That is, I define, say, 3 columns. The user can add/edit/remove rows. It can be one row at a time, that's fine. There are other fields on the form too, not related to this table. When the user is done adding rows of information, then they hit 'submit', and at that point, is when I grab all the data out of the control and save to a database (or xml file or whatever).
I've tried to build something with ListView and/or GridView.

We have many applications. All the applications are having there one access control. I am . All the application should refer this repository for access (We can say it one point contact).

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.

If i split the statements up they work fine individually.But what im trying to accomplish is to pass in the column name that i want to select from my table.. ill pass it from the page as well as 1 other parameter.
I was looking and found some queries that will return the column name from the table but figured this may work.when i execute this,it returns the actual value in my SET @column line.so in the below code if i run it, it will just return the value "VideoLevel"
BUT if i change it to the example below that,it works..

i am trying to bind data to a datagridview control on an ASPX webpage and am using something like this..
<asp:TemplateField HeaderText="MyField">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "MyField") %>
</ItemTemplate>
</asp:TemplateField>
the problem i am having is that the data for the 'MyField' field is actually an integer that is a reference to a string value in another sql table.
Does anyone know how i can reformat my code line above to show the string value instead of the int value?

my main intention is that, the exsisting table of sql server database(.dbo) with 1000's of records, that should be import to a new access database table(.mdb).for example if we want to had a new table in db2, of exsisting table in db1 with some conditions by using "select * into New_Tabel from (select * from Exsisting_Table where <Condition>) as objectName". Here the new table is created and records inserted in one execution in db2. The same work should be done for access(sqlserver db --> Access db).Here the new access database table with given name (as string_sysdate) must be created dynamically by clicking a button (multiples time creating new table).Is there any query or c# code for sql server database to access database.

I have a text box in which I want only digits (either decimal or whole numbers). I have applied Required Field Validator and Regular Expression Validator on it.I have an Image Button, by clicking on which, I want this validation to be performed. But when I build the code, and clicks on Image Button, these validators do not work and I am redirected to the server side method of Image Button and after completing the execution of server side method, control comes to these validators and client side validation executes.I am fed up by finding solutions on Google and unable to find any solution.Please tell me of anyone of you know the solution that why server side code is running first and client side validation is executing after server side code execution.

I've got a database that looks like this:
ID Name ParentID
1 1 0
2 1A 1
3 1B 1
4 1C 1
5 2 0
6 2A 5
7 2B 5
8 2B1 7
9 2B2 7
10 2B3 7
ParentID points to the ID field so that ID 2 is the child of ID 1.
Unfortunately, the order of the db elements is not guaranteed but what I'd like to do is have the information displayed sort of like in windows explorer with the children directly underneath the parents.
I've done something similar in the past with nested gridviews (ugh!), but it didn't point to itself and I knew how many children (additional db tables) there would be in advance. I'm basically trying to re-create that setup but make it much more flexible by making it point to itself.
Pseudo Coding I'd do something like:
Setup the html table and table headers Go through the DB from the top and search for the row with ParentID = 0 Add that row to the table Go through the db and find the row where ParentID = ID of Step 2)Add that row to the table Recursive magic go back to 4 Keep going deeper inception style ^^ Recursive magic go back to 2
I just have no idea how to even begin doing something like this!
This has nothing to do with my problem, but so you know where I'm going with this: after I get the table/gridview setup in the correct order, I plan on using jquery to hide all the non 0 parentID rows and make the rows clickable so that the child rows expand out underneath the parent row.

I have a question regarding a situation that occurs with GridView, ObjectDataSource in ASP .NET application. The GridView is linked to the ObjectDataSource and both are included within an UpdatePanel letting the GridView to fill in an asynchronous way from a form in the same page so it gets more rows as the user enters the data:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ReadOnly="True"
SortExpression="Name" />
<asp:BoundField DataField="Periodicty" HeaderText="Periodicty" ReadOnly="True"
SortExpression="Periodicty" />
</Columns>
</asp:GridView>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
SelectMethod="GetSessionNames" TypeName="Simulation"></asp:ObjectDataSource>
<asp:Label ID="Label27" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="NewWebSessionButton" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
I start the project with Visual Studio 2008, fill the form and it works correctly. Then I stop the execution: rerun again and the data I entered in the previous run is in the GridView. Is like some sort of cache saved the data from the session before. I checked that EnableCaching property is set to false for the ObjectDataSource. If I Rebuild Web Site in Visual Studio (not just Build) then it works corretly leaving the GridView empty. Is this caused just becuase of Visual Studio? Can it be turned off? And will it happen in the final IIS it will run on?

Currently I'm working on a extensive form, which I'd like to organise by grouping input fields in groupbox-like panels. These panels have an header, a minimize and pin icon. Also inner controls should be able to perform two-way binding to the FormViews datasource.
I can't find any builtin asp.net control that does the job. What is the best way to accomplish this feature request? Any examples available on this (can't find a decent one)?
