how to adding dependencies to output cache dynamically?

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.

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.

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

 Private Sub LoadGrid_CommentsField(ByVal Row As HtmlTableRow, ByVal BookingNumber As String, ByVal CommentsText As String)
  Dim Txt As TextBox
  Dim Cmd As ClickOnceButton.ClickOnceButton

  Txt = New TextBox
  Txt.ID = "txtComment_" & BookingNumber
  Txt.CssClass = "TFAppControls"
  Txt.TextMode = TextBoxMode.MultiLine
  Txt.MaxLength = 500
  Txt.Width = New Unit(95, UnitType.Percentage)
  Txt.Text = CommentsText
  Row.Cells(cComments).Controls.Add(Txt)

  Row.Cells(cComments).InnerHtml &= "<br/>"

  Cmd = New ClickOnceButton.ClickOnceButton
  Cmd.DisableAfterClick = True
  Cmd.Text = "Save Comments"
  Cmd.ID = "cmdSaveComments_" & BookingNumber
  Cmd.CssClass = "TFAppButtons"
  Cmd.EnableViewState = False
  Row.Cells(cComments).Controls.Add(Cmd)
 End Sub

On the line where i try and update the InnerHtml, i get the following error; "Cannot get inner content of  because the contents are not literal."

hello,

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 :

http://forums.asp.net/t/1588671.aspx

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?

I have set the output cache for 5 pages(5 minutes)

I want to clear  all these pages from cache on some nutton click 

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,
Paul.

Hi,

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? 

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?

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
                    lb.Items.Add(sect)
                Next
            Next

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
                Next

            Next

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.
