DataSource Controls :: SQLDataAdapter Postback / Create A Class, DataCommon, To Contain All SQL Data Manipulation Functions?
Apr 22, 2010I'm trying to create a class, DataCommon, to contain all my SQL Data manipulation functions. I've created a Subroutine called Init that initializes a SQLDataAdapter:
[Code]....
From my other classes I am creating an instance of DataCommon, calling Init, and calling another subroutine in DataCommon that pulls data from SQL and loads the data into my dataset. This part is working great -- no problems at all. I'm loading three different Datatables in the Dataset with no issues.
At this point, I'll perform my various manipulations on the datatables -- add/delete/modify rows -- again with no problems. All of this is creating postbacks...and this is where my problem begins. After I've done all my manipulations to the data and am ready to update my SQL tables, I have to re-initialize my SQLDataAdapter. I thought I could do something like:
[Code]....
But I get the error: Exception inserting Class. Thread was being aborted.
In my initial data load from SQL, each datatable is getting loaded from a single SQL table, so I was hoping to use the autogenerated Update/Insert/Delete statements by the SQLDataAdapter. As a test, as soon as I filled the dataset initially, I added a new row to one of the datatables and used the SQLDataAdapter.Update() method before a postback occurred, and it worked perfectly.
So, with all that being said, I guess my question is, how do I reconnect the table mappings between my SQLDataAdapter and dataset to autogenerate the updates after a postback occurs? I've tried researching this, but I get confused after reading about FillSchema vs TableMappings vs everything else I've read about.

View 3 RepliesWeb Forms :: Accessing Functions From Controls?
Jul 1, 2010I have made 3 web controls which need to be accessible between eachother. First control is main control (controlA). Other 2 controls (controlB and controlC) are referenced in controlA. Now i need to access function from controlC and call it in controlB. I tried adding new reference, but it doesnt work the way I want it.
ControlA is main control and it is merely a table to hold other 2 controls in place. I can access both controls from controlA, but since I need to modify controlC due to drop down menu in controlB i can't force controlA to respond to event in controlB every time it occurs and affect controlC. Or can i? :)
So whenever the event (SelectedIndexChanged) of drop down menu occurs in controlB, I need to set up/change controlC. Problem is, I don't know how to call function from controlC. It may sound very simple to solve and i tried to make a new instance of controlC class in controlB my webpage just wouldn't load.

Callback Functions For Server-side Controls
Mar 27, 2012I have an ASP.NET control (a button) in a WebApp. It has an onclick attribute:
onclick="SaveButton_Click"
SaveButton_Click()
is a C# function in the codebehind file. When the user clicks the button, SaveButton_Click() is executed.
What I would like to know is whether there's a way to set up a javascript callback junction. I know how this is done in AJAX, but I'm not sure in ASP.NET (with controls that run on the server) how (or if) this can be done.
Web Forms :: Dynamically Adding Controls To A Table Across Multiple Functions?
Mar 13, 2010I'm looking to add controls dynamically to a table across multiple functions. I'm trying to convert this from a C# app to a web app using asp.net, though this is my first time using asp.net with no web development background. I read the creating tables dynamically in the FAQ but I'm still not sure how to do this.
When pressing the submit button on my form, it will create a table in a place holder. Eventually I would like it to generate urls based on the users input and do this in a function other then the one I created my table in.
In my C# app I was able to add text to a listbox using: lstOutput.Items.Add("Text"); across multiple functions but I'm having trouble doing this with a table.
I understand that my table is a local variable in the submitButton_Click function, but how do I make it global to add rows, cells and controls to it in other functions?

Forms Data Controls :: Gridview SelectedIndex Not Updating After Sorting / Paging Functions Are Called
Apr 12, 2010I have been researching this issue for a couple of days and have found a lot written about it, but none of what I have found has fixed the problem I am having.
I work for a school system, and my principals are wanting to take a list of the staff members at their school and create staff lists for different activities they perform. I thought I would load the staff into Gridveiw1, and when they select a record have it move over into Gridview2 and "delete" from Gridview1.
I am loading my full staff into a datatable (SQL Server backend), and setting this datatable as my gridview1 datasource. At this point, it loads great, and cosmetically speaking sorts and pages fine. The problem occurs in the codebehind after a Sort or Page change has occurred -- when I select a record and move it over into Gridview2, it is moving the original record that was at that postion on Page 1 instead of the sorted or "new page" record.
So if the initial list comes in as:
Teacher 1
Teacher 2
Teacher 3
The sort button is hit so that the list now starts out like:
Teacher 7
Teacher 13
Teacher 5
If they select "Teacher 13" to be moved over after the sort, instead it is still moving over "Teacher 2" -- the initial teacher in that index before the sort.
The Gridview setup on my aspx page looks like this:

Iis - ApplicationPoolIdentity Permissions On Temporary?
Jun 8, 2010We have a web application that runs on a WIndows Server 2008 64 bits machine. The app's ApplicationPool is running under the ApplicationPoolIdentity and configured for .net 2 and Classic pipeline mode.
This works fine up to the moment that XmlSerialization requires creation of Serializer assemblies where MEF is being used to create a collection of knowntypes.
To remedy this I was hoping that granting the ApplicationPoolIdentity rights to the ASP.Net Temporary Files directory would be enough, but alas..
What I did was the run the following command from a cmd prompt:
icacls "c:windowsmicrosoft.netframework64v2.0.50727Temporary ASP.NET Files" /grant "IIS AppPoolMyAppPool":(M)
Obviously this did not work, otherwise you would not be reading this :)
Strange thing is that whenever I grant the Users or even more specific, the Authenticated Users Group those permissions, it works. What's weird as well (in my eyes) is that before I started granting access the ApplicationPoolIdentity was already a member of IIS_IUSRS which does have Modify rights for the temporary asp files directory.
And now I'm left wondering why this situation requires Modify rights for the Authenticated Users group. I thought it could be because the apppool account was missing additional rights (googling for this returned some results, so I tried those), but granting the ApplicationPoolIdentity modification rights to the WindowsTemp directory and/or the application directory itself did not fix it.
For now we have a workaround, but I hate that I don't know what is exactly going on here, so I was hoping any of you guys could shed some light on this.
