View 3 RepliesOn the items in my listview, I have a button to allow for editing. The strange thing is, that the button only changes to editmode on the second click of the button, and then it doesn't load the data from the item. I have tried to debug this issue, and it does cause a postback on the first click, but nothing happens. Then on the second click, it fires a postback again and changes to the edittemplate, but without any data.
I databind my listview on

View 1 RepliesI know that when a .NET web application first starts, it will be slow on first access. For that reason, I created a 'keep alive' page in the application that is requested every 8 minutes or so by a scheduled process. I hoped that that would be sufficient to prevent the application from 'unloading' and thus suffer from this initial long startup time again and again.
I can see in my logs that the 'keep alive' page is indeed triggered every 8 minutes, 24 hours a day. But when I actively start working in the application after some time, eg. the following day, I still have to wait a while for it to start up. Once the first page is loaded, all is fine again.
I've developed a web page Client.aspx that is used for editing a client. This application has been deployed and I made sure that debug='false'.Upon selecting a client from the dropdownlist, his/her information is retrieved for editing. This retrieving process is very slow( about 9 seconds).Except this DropDownList, all the other controls on this page are within the Update Panel. There are 2-3 other Update Panels within the main Update Panel.
When a client is selected from the DropDownList, the Client_ID (DataValueField) is used to retrive the informationSELECT * FROM CLIENTS WHERE Client_ID=1576
This method returns a dataset.In the calling method I'm assigning these values to the respective fields.Some JavaScript is used for validating Phone#.I also have a RadioButtonList on this page. When one of the ListItem is selected I need to disable a TextBox. Even this process is taking much time than expected.
While I was using adrotator for flashing banner it was working so slowly(poorly) that it did not serve any purpose. Actually i was trying to display all the products of a company by flashing them one after another in a window. provide me some other better alternative for the purpose or any other control, provide some code snippet.

what is the best way to show/hide controls in .net?
I have a page with many show/hide depending on the control value.
eg. radio button list rbl (dynamically generated from the database values)
based on the radio button list value,will need to show/hide the other controls.
if the value is 1, will need to show or hide dropdownlist1.
if the value is 2, will need to show or hide dropdownlist2.
I tried using the javascript with rbl.Attributes.Add("onChange","return toggleDropdown();")
then in my javascript function i will show/hide the control.
However when I toggle the dropdown for the second time, it became very slow. The first time is okay.
I have also tried using ScriptManager and UpdatePanel (putting the controls inside the UpdatePanel), but it is also very slow when toggling dropdown for the second time onwards, causing the page to hang.
I'm not sure if this belongs here since it doesn't seem to be a coding issue but...
I am having an issue with using httpwebrequest - the first time I run HttpWebRequest on a page there is a 5-10 second lag before it returns the data I am looking for. It doesn't matter from what source I am polling the lag is always there so it has nothing to do with the sites I am connecting to.
After I poll the first time as long as the page is reloaded within 1 and a half minutes afterwards the httpwebrequest response is lightning fast.
If I wait a minute and a half to 2 minutes without reloading the page the lag returns again.
I've tried everything related to tweaking the httpwebrequest settings and none have had any impact whatsoever.
If it helps I have older pages that use classic asp that behave the exact same way when returning data from external websites so it seems to me like a server issue.
What I am left with is...
