I have an ASP.net page which has fields for filtering a dataset. When I apply the filter (through a button), the results load fine. If I navigate to another page (on the same session), and then come back to the page, I'm re-setting the value of the filter fields on page load
View 9 RepliesClicking on a link button on a page causes Postback to a page containing a number of controls. [code]During the Postback to (page a) on the server, (page d) is requested when using the IE browser (doesn't happen in Firefox) there are absolutely NO artefacts requested that live on (page d), there are no response redirects or server transfers or anything referencing (page d).The only thing I have seen like this is when an image or artefact is requested and cant be found, or some pathing issues for an image, and this somehow screws the request up.

I have more than 30,000 rows in a table. It takes a lot of time to load all the data in the gridview. So I want to display 100 rows at a time. When I click next page button, another 100 rows should be displayed. When I click previous page button, previous 100 rows should be displayed. If I type page 5 in a text box, then I want to jump over to the 5th lot of rows.
I also want to display how many pages there will be. Can we implement this concept in vb.net [winform] gridview. I am using database PostgreSQL.
I have a need for a button to take the user back to their previous page.Because of how this page is accessed, the only way to do this is with javascript using history.back()
This part works perfectly apart from the fact when a user goes to click a button on the page they have gone to back to, I get the error that Request.QueryString is not supported in this context.I'm guessing the Request object is lost when javascript is directing the user to the previous page.I cannot use Request.UrlReffer either because the the nature of the back button. (it causes a loop at times).

I have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
I'm not sure why the following code is not working as intended:
CODE:
Where litMessage is the name of the literal control and messageBody is the name of the string variable.
My intention is to output a string onto a web page and to replace the line breaks with a br tag so that it can be displayed on the page correctly. However, nothing is replaced. When viewing the page source, it looks like the line breaks still exist in the string. Similarly, when displaying the string via MsgBox, it displays normally as well. I have also tried wrapping the output with the pre tag and it displays the line breaks properly as well.
The string was originally entered by a user through the use of an asp:Textbox and saved into a MSSQL database. It's retrieved and displayed on another webpage using an asp:Literal control. The only thing that happens to the string before it is submitted is that it is trimmed (i.e. textbox.Text.Trim()).
Perhaps there is something I did not consider?
Edit #1: Due to time constraints, I've decided to just wrap the text with the pre tag. It's an acceptable work around as it preserves the line breaks. Unfortunately, it doesn't explain why the code didn't work in the first place. In the meantime, I'll just leave the question unanswered until I find a proper answer.
Edit #2: Solution found and answered below. UpdatePanel tag added to the question for future reference.

View 9 RepliesI have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.
