Disable Caching In NET WebBrowser Control?
Aug 6, 2010I have been googling for hours and trying to figure this out, and I just can't.I have 1 webbrowser control on a form, webbrowser1. Once I load a page, say google.com, if I use webbrowser1.refresh() or webbrowser1.navigate("google.com"), it's not reloading the page, it has it cached so it's just reloading the cache. This is terribly apparent especially on pages like forums or craigslist.

Jul 20, 2009I have an aspx page with three web controls: one to control the List Users page, one to control the Edit Users page, and one to control the Add User page. I have discovered a method for accessing these elements, but it seems to be limited. Here is what I have done:
Protected Sub editUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs)
'set selected user from gridview.
[Code].....
This works in most cases. However, I am unable to access the "enabled" attribute of these web controls. Why is this, and how might I access that attribute?
Disable Page Cache To Force Page Load With Browser Back Button
May 7, 2009I have an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.
'Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1))
'Response.Cache.SetValidUntilExpires(False)
'Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches)
'Response.Cache.SetCacheability(HttpCacheability.NoCache)
'Response.Cache.SetNoStore()
When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.

May 24, 2010The problem is, the document is taking 2-3 seconds to process and print it. While it is printing this status box shows up and the default focus is on the cancel the button. The end-user(s) have a nagging habit of pressing enter twice, thus they end up canceling the print.
Here's the basic code I'm writing for printing the receipt.

VB Datagrid Disable AutoScrolling Focus On Selected Column?
Jun 7, 2011My problem is I have a data grid in Visual Basic, it works fine but as the columns extend past the width of the window I needed a scroll bar. This is where the problem arose. When a column past the 4th is clicked the scrollbar will shift to give it focus. As there are check boxes here they are constantly clicked and when they are the scroll bar shifts but the button isn't checked and must be clicked again. I was hoping there was a way to disable this Auto focus so clicking a column will not cause the scrollbar to move.

View 1 RepliesPrint Selected Pages From A Multi-page PrintDocument1 Report?
Nov 10, 2009I have a data-driven many-page print system that works well, each page containing logically what's next following the preceding page. To output a sub-set of pages, how can I avoid outputting pages before the first one that I actually want to send to the printer? To pick and assemble the data correctly my PrintDocument1 process has to run until I reach the 1st page to print, so it would be neat at the end of each unwanted page to 'waste' them - then from the 1st wanted page the usual e.HasMorePages will do the job.
I thought maybe PrintDocument1.Dispose() or PrintDocument1=Nothing might void the early pages I don't want (then looping back internally to construct the next page), but no. Is there another way to 'ditch' pages until the required one is reached? Or do I have to avoid using every e.Graphics.DrawString) statement until I get to the right start point? That would of course do the job, but is pretty clumsy
Reload Page Data Based On Dynamic DropdownList Selected Value
Oct 26, 2011I have a bit of a tricky scenario. It consists of some partial problems for which I have individually found solutions, but I couldn't find anything that makes it all work together smoothly.
-Upon selecting an item in a datagrid, a new page loads with the details regarding that entity.
-The entity represents a product that can have any amount of variants (such as a t-shirt's color or size)
-I dynamically add dropdownlists to this detail-page that represent these variants (there can be any amount of variants, and each variant can have any amount of different values, each value or combination or values from different variants representing a unique product entity)
-Upon selecting a different variant in a dropdown, a delegate is called that will change the session variable to the productId associated with the selected variant and a postback is fired that will reload the page with new data based on this productId
The problem: the postback is fired BEFORE the dropdownlist's (OnSelectedIndexChanged) delegate is called. Since this delegate defines the productId in the session, the new to-be-used productId isn't known at the time of postback.
Result: loading the correct data in the page is always delayed by one postback. Each time I change the selected index of any of the dropdowns, the page is loaded with data based on the session variable that the PREVIOUS OnSelectedIndexChanged delegate of the dropdown set.
I have a LoadData() method that sets the values of all textboxes, fields, labels etc. based on the productId stored in the current session. This method is called on Page_Load.
Private Property CurrentProduct As Product
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
LoadData()
[Code] .....
It seems that I haven't been completely clear on what does and doesn't apply to this scenario regarding Page Lifecycle.
1) My dropdownlists are added dynamically, which works fine on the first page_load.
2) The content of the dropdownlists is defined by what entity's details i'm loading on the page.
3) What entity's details I'm loading on the page is at first(not-postback) defined by the product I selected in a gridview in the previous page.
4) At postback, this entity is based on a sessionvariable containing the id of the entity.
5) This session variable is defined by what item in the dropdownlist I select.
6) This dropdownlist dissapears after postback since it's not defined on the page, but dynamically. So is the event.
So my guess would go towards some clientside script that stored the selected value before postback, but then I would be clueless on how to get that variable to the server since the logic that retrieves the entity is in the business logic layer which is far away from this page..

View 2 RepliesASP.net: Gridview Datasource Caching ?
Sep 16, 2010I currently have a control that called MyGridview that inherits Gridview. It has a paging template within it for customized paging options, and I'm at the point where I want to cache the initial datasource for better performance.I haven't done this in a long time, so perhaps there is a different solution these days with the newer frameworks.Before, I simply used a Cache object that was named whatever the gridview was named. I couldn't use the same gridview name through the application though.Is there a best way to have a cache object, or some other object like a session within the control to store those unique datasets for paging and sorting?

Caching Propertyinfo Of Abstract Class?
Jan 19, 2012I've been playing around with implementing an abstract base class that using reflection accomplishes SQL to Object mapping.
I did some benchmarks and decided I wanted to implement a caching strategy for the property info of the objects (to prevent future lookups on them). My first instinct was to try and implement something like this.
Public MustInherit Class BaseModel
Implements IFillable
Private Shared PropertyCache As List(Of PropertyInfo)
