dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Cutting Edge: Implement Custom Cache Dependencies in ASP.NET 1.x


One of the most compelling improvements that ASP. NET brought to ASP programming was the Cache object. The Cache has some similarities to the Application object and is a container of global data (as opposed to session-specific data) that features a fair number of innovative characteristics.

Wicked Code: Supporting Database Cache Dependencies in ASP.NET


Developers love the ASP. NET application cache. One reason they love it is that ASP. NET lets them create dependencies between items placed in the cache and files in the file system. If a file targeted by a dependency changes, ASP.

Adding carriage returns between 2 dynamically created controls in an HtmlTableCell


The title pretty much explains it. Here is what i'm trying to do...

output cache to be used only when parameter has changed + old question of user control not answered



i have 2 questions about output cache:

1.is it just me , or does it seems that it is used only after the second time that the user reaches the webpage? if so, why, and how can i tweak it to my needs? my guess is that it wouldn't be logical to cache every time a user reach a webpage, but only when it happens enough times.

2.i know that i can use "varybyparam" for using the output cache when the parameter doesn't change , but it seems that it would use the output cache even if there is no parameter , or if the specified paramter is not there. is there a way to overcome this?

3.an old question that somehow marked as "answered" , yet i didn't solve : suppose i created a user control and i gave it values through the CTOR via the aspx file . is it possible to show the values from within the split/design mode? remember that i've talking about ASP.NET and not simply C# winforms . i write this because this question was on :


and the answer that i got was for C# and winforms . i've tried to do the same for ASP.NET , but i've failed.

can anyone please help me?

Load dynamically assembly with dependencies

I'm trying to download .dll by having some url (http://somedomain.com/myassembly.dll) and load it into appdomain. Once I download this assembly I can't load it into appdomain, because it has some dependencies. Some of these dependencies I can found on my local machine (such as .NET libraries), but some of them I have to download and load into appdomain. So there are several questions: 1. How to determine list of dependencies without loading assembly into appdomain (and by having only byte[] as assembly) 2. How to determine which of these dependencies can be found locally Thanks, Paul.

Dynamically adding User Controls -- newbie question!

I am new to ASP.NET (coming from ColdFusion, thank goodness I'm away from that!).  And I am have THE hardest time understanding how to work with forms in ASP.NET.  Here's what I am doing:Dynamically add User Controls to a PlaceHolder based on some int value (which currently is passed in a HiddenField).Fire an event if the WebControls inside of the User Control change, then handle that event in the Main Page (i.e. save the input to DB)When the user clicks the "Next/Continue" button, the next controls for the next page are loaded.And I guess maybe I just can't seem to get how things work in ASP.NET, because I am really struggling with the general idea of how ASP.NET flows.  Should I be dynamically loading the controls in Page_Init, or Page_Load?  Or should I load the controls when the buttonclick event is fired?Do I have to add the axCtrl.OnDataChange += new EventHandler(HandleAxControlDataChange); line on Page_Load?  Or should I put this in When I first load the UserControl, I need to initialize some WebControls within the UserContorl.  Is there a way to know if I have loaded new user controls into my placeholder?  I can't use Page.IsPostback, because after the first page, every page is a postback from the buttonclick.Any help for this confused newbie would be GREATLY appreciated!!Here's what I have: pu

WPF: Adding checkbox with content Textblock at dynamically - width width returns NaN

Getting GridSplitters to function after dynamically adding WorkflowDesigner views

I am new to WPF and an writing a program which re-hosts an instance of the WF4 System.Activities.Presentation.WorkflowDesigner.   The program itself works fine, but I am unable to get either of two vertical GridSplitters within a nested Grid to work properly once the WorkflowDesigner's view is assigned into that grid at runtime.   (The GridSplitters work until the WorkflowDesigner and PropertyInspector are created and its views set as children of the nested grid). The window has an overall layout grid (OverallLayoutGrid) and nests the original layout grid (LayoutGrid) as the middle of the three row OverallLayoutGrid.   The outermost main OverallLayoutGrid as three rows and one column.   The Main Menu is in the first row, the nested LayoutGrid is in the middle, and a StackPanel with an error displaylistbox and status bar is in the last row. The nested LayoutGrid has 5 columns and one row layed out with: Col0 - Vacant in static XAML, System.Activities.Presentation.ToolboxControl added during Window load Col1 - "LeftGridSplitter" Col2 - Vacant in static XAML, System.Activities.Presentation.WorkflowDesigner.View added during "File | New" creation of new workflow COl3 - "RightGridSplitter" Col4 - Vacant in static XAML, System.Activities.Presentation.WorkflowDesigner.PropertyInspectorView added dur

Adding multiple usercontrols dynamically


Hi all,

I have a simple user control which contains a textbox and a dropdownlist. I need to add this control multiple times to my page then save the details to my db, validating each control. When they re-enter my page I need to load the user control for each record in the db populated with the data they entered. They can then edit the data, delete the row or add new rows.

I'm trying to find the cleanest most efficient way to accomplish this. I realise I would need to re-add the user controls after each postback re-populating the data. Would the best way be to add each row to an arraylist or list of type object, save it to the viewstate and re-add the controls with data on postback, or is there another method which would suit?

I've looked high and low but can't find anyone with a similar problem/solution. 

Any help is much appreciated,

Adding Controls dynamically in the infopath form - A standard Expense Entry scenario



I am having a requirement where I need to create an Expense Report Entry form using Infopath 2010. 

1) The form would have pre-defined columns/Controls like Exp.Type(drop-down) , Details , Location, Amount , Curruncy, Date etc..

2) User can enter/update as many line items as possible by clicking Add/Update/Delete for the each line items. So basically its like adding the same row dynamically.

3) When User Submits, I need to capture this data and post it to SAP where I am using SAP web Services.

Can you please suggest if this is possible in InfoPath form ?

If Yes, how can I achieve this dynamic line items functionality in InfoPath

And how can I read the data using the code so that I can Post it to the WebService? 

InfoPath Forms : Adding rows dynamically from a SQL table along with a 'Delete' button per row


My requirement is something like this:

In a Task Approval form, I want to have a view which shows all the rows in a particular SQL table (in a infopath repeating table?). Along with each row, there should also be a button, on clicking which the row should disappear from the infopath view table. Do you think InfoPath can handle all this? :) 

To summarize:

1. How do I add rows to a table dynamically?

2. Per row, how do I create a button dynamically?

3. How do I remove the row from the view when the button is clicked?

Adding Multiple Selected Values to ListBox Dynamically


I have a ListBox control that gets populated from a database like this:

For Each gvr As GridViewRow In GridView1.Rows
                Dim lb As ListBox = CType(gvr.FindControl("SectionsListBox"), ListBox)
                For Each sect As String In sectionlist


Then the selected values also get populated like this:

For Each gvr As GridViewRow In GridView1.Rows
                Dim lb As ListBox = CType(gvr.FindControl("SectionsListBox"), ListBox)
                Dim faqid As Integer = gvr.Cells(0).Text
                selectedlist = oCMS.getFAQSections(faqid)
                For Each sect As String In selectedlist
                    lb.SelectedValue += sect


I need to have multiple selections, but I cannot get it to select multiple values with this line "lb.SelectedValue += sect".  The listbox has been set in aspx to allow multiple selections.
