Web Forms :: Dropdown Selected Value Of User Control On Page Load?
Jul 15, 2010
I have a function on page load which will work based on dropdown selected value. and I am using this dropdown in a user control. So getting problem because the dropdown value is not loaded yet before Page Load. How Can I do that using those control still.
Here is my code below.
public partial class GradeEntry : System.Web.UI.Page
StudentManager studentManager = null;
CourseManager courseManagerObj = null;
GradeManager gradeManager = null;
In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
I have a user control that will basically be a header in most of my pages, but not all. I want some code in the user control to be run before the page load event of the page that holds the user control, but the page load event fires before the events in my user control. Is there a way around this?
I have a page called "EDIT.ASPX" on that page it has come TextBoxes, Label and 3 User Controls. When the Edit.aspx page is loaded all the correction form Controls are loaded properly, even the User Controls loads with no problem. The problem that I am expericing is that on the User Control I have a CHECKBOX with AutoPostBack="true". Each time the user click the CheckBox the User Control disappear. NOTE: How do I fix this problem and eliminate my page control from vanshing. The user control needs to keep the same state as the Edit.aspx page when the checkbox is clicked. I need to be able to click the checkbox without loosing any data on the page rather it's the Edit Page or the User Control.
I have an EDIT.ASPX page and on that page I have some labels and textboxes and a user control. I listed all the related codes you can have a clear picture - not all of the codes are given me a problem. ONLY ONE.
HELP ---> On the Uer control (SiteTemplate2.ascx) I have a DataList that is being populated by the database and that works fine. I have a CHECKBOX on the user control page each time the user check the CHECKBOX the user control content totally disappears from the EDIT.ASPX page. There is no error message -- I believe this is a post back error but I don't know how to fix it.
Goal: Each time the checkbox called (CHKBSideBar) is clicked on the user control page all of the page content should stay in place that include
EDIT.ASPX Page and the refeneced USER CONTROL. I should be implement a CheckedChanged Function without either of the pages lossing DATA. I need to be able to access post back event from the user control of the Edit.aspx page. When the user click a box on the user control page how do I keep the same Page_Load event on the edit page. I need to reference the Edit page from the user control.
Note: The edit page loads the user control (SiteTemplate2.ascx)SEE CODES BELOW
I know this is a lot and thank you in advanced for your help. I tried to include all the pages that are key players. I must user the user control bacuase the user can select different template so eliminating the user control is not an option.
I am new here so I will try and give you as much detail as I can:

I am developing a web site that has holiday prices which are taken from a different database and loaded into two SQL databases.I have two girdviews to display each of the prices data.What my issues is that I need to load an SqlDataSource on database 1,when 'Family' is selected from a dropdown list and run an SqlDataSource on database 2 when 'Themed' is selected and then run both when 'Don't Mind' is selected.
I have a page with 14 dropdown lists. In the first page load (ie. not isPostback) I set the selectedIndex of the dropdownlists individually but I find that they are all set to the value I use for the last dropdownlist set. Here is the code
comboFirstJudge1.SelectedIndex = 0 comboFirstJudge2.SelectedIndex = 0 <so on for all the dropdown lists until the last one> comboFirstJudge14.SelectedIndex = 4
The result is that all dropdown lists have SelectedIndex = 4. If I run the same code on a postback it works just fine (the first lists have SelectedIndex = 0 and the last one = 4).
I have 2 web control calendars on a web page where I allow the user to select a startDate (WebControlStartDate) and endDate WebControlEndDate. Then the user can click the "Refresh" button to update the report that is displayed.
I am able to successfully store both the startDate and endDate value in a session variable and after the user clicks the Refresh button then both the StartDate and EndDates are chosend on the start and EndDate calendars.
However, both the StartDate and EndDate calendars are defaulting to the current month, meaning even if I select a previous month after refresh I will have to click back to a previous month in order to see the selected Day. After clicking refresh I want both month displays on the web control calendars to disply the months that were selected.
To summarize: each calendar is selecting the correct dates I just want the pageLoad to display each selected Month after the user clicks the Refresh button.
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
