i built a user control for login process, i'm using it in some of my pages, but something
wierd happens, in some pages it works fine, and in some page he just doing Postback,
and put this in the url:
?ctl00%24ContentPlaceHolder1%24LoginBox1%24TxtUserName=&ctl00%24ContentPlaceHolder1%24LoginBox1%24uiTxtPassword=&ctl00%24ContentPlaceHolder1%24LoginBox1%24SignInCmd=Sign+In
I have a abc.aspx page having some control like (drop downs, text boxes), i am filling a grid based on selected items in the drop downs and date selected from the ajax calender extender control attached to the from data and to date text boxes.
Inside grid there is a link which redirects to bcd.aspx, this page (bcd.aspx) is having a back button to redirect abc.aspx.
Now what i want is, abc.aspx should main its state like grid, drop downs and text boxes should be shown as it was earlier, i.e. all should have same values as it was at the time of redirecting to bcd.aspx.
Yes, there is a way to maintain the state by passing all values from query string and than get all values back and rebind all controls. But i don't want to go this way because i will have pass so many values in query string.
While I am running a webpage by doing a right click on it and selecting 'View in Browser' in Visual Studio 2008; it popping up the following error:-
ERROR

I have 2 - DropdownList controls, which i am filling at severside when page loads. After the user selection in DropdownList1, i am changing the contents in DropdownList2 values. This validation (i.e. changing the contents of Dropdownlist2 values) am doing in Javascript Clientside. But on postback i am not getting the values in DropdownList2. When i say "DropdownList2.Items.Count;" getting "0". I tried to put the contents of DropdownList2 in ViewState on pageload. But i am getting Serialization error at runtime "Viewstate["PersistValues"] = DropdownList2;". I am using html input hidden control to pass the values from server side to clientside for my validation. Now, to meet this requirement i am Binding the DropdownList2 at postback again with first DropdownList1's selected index (This is repeat of logic which i have done in Clientside).

I've got an issue with the postback property. I have a chart (Code below) which has two series pulled from a datasource.
Both series display fine but I've enabled the bars in the chart to respond to the click event and when items from the first series is selected, everything works fine. However, I try to pull the x value for the second series, which is supposed to be a date, but all I get is an interger.

I have a page (page1) with 4 controls that serve as the parameters for a report. The submit button does a cross page postback to another page (page2) that contains a ReportViewer control.Unfortunately, I cannot read the values from page1 once I get to page2. Here is the source to page1:

In other situations I have passed such values in the query string and then assigned them to the parameter collection, no problem.Also, please note, I have tried using the @PreviousPageType directive to get at the types on page1, but have met with no success there either.

I'm working on an asp.net app and I have some controls that are created dynamically on the OnInit event. One of that controls is an asp button that has been working fine until now. When I add a ScriptManager to my page, that same button is unable to postback. It's only working if a take the ScriptManager out. Has anything like this ever appened to somebody else? Am I invalidating the page somehow? Edit: This is my script manager tag:
<asp:ScriptManager ID="ScriptManager1" runat="server"
EnablePageMethods="true" EnableScriptGlobalization="true"
EnableScriptLocalization="true">
</asp:ScriptManager>
//My Dynamic Button:
Button button1 = new Button
{
ID = "button1",
Text = "Ok"
};
button1.Click += new EventHandler(Button1_Click);

I have several control event handlers that need to use the same function. Where is the class defined and how is it instantiated within the event handlers?
