I have pages with lot of controls (datagrid, treeview, listview, checkboxes itd...). Each control have event usually SelectedIndexChanged and that is ok. On page load, I read default values from database and set controls selected or not. Problem is that in this case fires every damn event of each control and causes problem with loading page. I want to completely turn of runing of all events while triggered from page.load event? Is there nice solution for this? I dont want to mess with RemoveHandler and AddHandler in page.load procedure (although I tried to remove handler, change selected index and then add handler, all in same page.load procedure but it doesnt work).
Is there possibility to turn all events for load procedure, or to use another procedures (init, preinit, loadcomplete, prerender...) to store default values readed from database?
Or can I somehow figure out from witch procedure is called event, then I can implement something like this to skip executing event:
On a page with some user controls, I need to execute some lines of code only once (i.e. not on postback), however, the code must run after ALL page objects complete loading.
Example, Page1.aspx also contains uc1.ascx and uc2.ascx. If I imbed the code in a if (!PostBack) code block, it will end up running before the corresponding page load is completed for uc1 and uc2.
Is there a way to run the code on Page1.aspx once AFTER all the objects on the page have run thru their page load events?
I have read that you can not disable the back button on page load but I can clear the cashe on page load so the back button would then be greyed out. I have read a few articles on this and I am unable to get it working. I am using MS visual web developer 2010.
I have an asp.net C# website. Because of iPhone doesn't support flash i want to change a theme of my site on page load or init if user using it. Could any one show me (code in c#) how to determine that user is browsing my website using iPhone or iPad, not a blackberry, or android etc.
I'm using ajax 3 tab panels on my web page, whenever my web page is loaded i need to disable rest 2 tabs (to grey out with no click events).
when i tried to do this from server side, the tabs are completely hidden instead of disabling. My actual requirement is to use tab container as asp wizard control.
i'll be having form fields in my first tab with submit button, when the submit button is clicked, then the disabled second tab will be enabled and in the the second tab when submit button is clicked the third tabpanel needs to be enabled just as a wizard control.
i can use wizard control but, i'vent found any styled asp.net wizard control. How can i disable rest of the 2 tabs when the page is loaded.
I've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
Since PostBack data and viewstate data are available and initialized to their respective controls at the time of page PreLoad() event ,i want to know then which place is better to use - either PreLoad() or Load() event for dynamically checking my controls status ?For the last one year i was blindly using Page's Load() event .Why i was using Load() event ? I think the same logical part can be done in PreLoad() , since data are available at that time .But what is the main difference when i use my logic Here(PreLoad event) or there (Load event) ?
I hv Declared two Master page one Is Base and Derived.. Base Page Load is working but when i hv written load controls in Derived Page Load Using C# it's not working..
I'm trying to create a page that displays a databound gridview to the user showing them the items being processed. Then the page should immediately begin processing. The problem is that the page never shows the gridview (or any other control) until the process is complete. The process is being sent to a WCF service. I've tried setting the page to async and running the wcf in async mode but the content still fails to display.
I have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.
I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
There is a dropdown 'ddlpageName' on a page where all the pages are listed.
Now When I select the particular page name from the ddlpagename, all the events (like page_load, grid events ,dropdown events) should be listed in other dropdown named ddlevent.
