Can I modify the properties of a content page control from an event fired from the master page?create a delegate and event on master page wire up the master page in the content page create the event handler (function) on the content page modify for example:
contents of the Text property of a textbox render a control visible (or hidden) etc...
on master page, i have declared a label control & set value to it.now on content page, i m able to find the control, but the value is alwasy null & not the one which was set.when i debugged, content page's load event is called first, after that the master page is called.so where should i access the master page control so that i get the set value.
When Bing map control loads for first time on any browser all pushpin on map are visible.
Bing map control renders perfectly.
Then I refresh browser it create rendering issue some custom pushpin on map gets disappeared. This behavior continues with pushpin. Pushpin are (.png) images and I am not using default bing map thumbtacks.
May be it is issue of browser caching content or Bing map control rendering issues on various browsers.
I have a web page (Orders.aspx) that gets some orders and show them in a Gridview .The orders list I get from DB is depend on a field named Status. The page has a master page that contains a Tab user control. The user control has several tabs and every tab has a different Status. Therefor, when the user clicks on every tab, I want to pass a value as status to my content page (Orders.aspx) and then select the orders from DB based on status.
