Web Forms :: User Control Refresh / How To Trigger A Postback
Jan 27, 2011I have around 8 user controls on a page with a form in each of them. I have a dropdown list that allows you to select a form, with a selectedindexchanged event that hides the current form and shows the requested form.
There is some javascript that needs to fire when each form loads. Now, when you click on a form for the first time, the javascript fires as it should, but if you click the dropdown to change the form, then click back to a previous form, the javascript doesn't fire (because the user control is already loaded).
Is there anything I can do to trigger a postback, or reload/refresh the user control whenever an option is selected from the drop down?
Web Forms :: Trigger A Postback Or Self Refresh A User Control?
Jun 5, 2010I need to trigger a postback or self refresh a user control from one of the functions in the same user control.
Problem is that I am setting the selected value of a dropdown control in this usercontrol but it does not actually show up until after a postback.
This I came to know after I found that the said drop down shows the current value only after I click on another button.
I need to do this on the server side in the function given below:
public void FillDropDown()
{
FillProgramList(select);
//if (Request.Cookies["prgname"] != null)
//{......
Can Create An ImageButton That Doesn't Postback
Apr 24, 2010I'm trying to use the ImageButton control for client-side script execution only. I can specify the client-side script to execute using the OnClientClick property, but how do I stop it from trying to post every time the user clicks it?

Mar 22, 2010I have one web control in a page.
Lets say i have a web control that has one <asp:textbox id="action" text="getArticle"> and one <asp:button ...>
If i press the button, a postback will occur but will not load this web control again but it is supposed to load another web control.
How can i obtain the value of the textbox. The issue is that the web control is not loaded so findControl("action") will return null.
What is the correct approach to handle this? Should i use url parameters? Is there another way.

View 1 RepliesAJAX :: Page Inside Update Panel Doesn't Refresh The Session Object After Postback Of Any Control
Oct 1, 2010I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

VS 2010 Dropdownlist Doesn't Trigger Event
Mar 17, 2011I populate the items to the dropdownlist with values from a database. I use the .text and .value properties. It comes out right in the list. However when I try to make a button visible when selectedindexchange or selectedtextchange, nothing happens. Therefor I made the button always visible (because itīs the "add" button to the database depending on the selected item). When clicking Add I realize itīs the same value being sent to the database everytime, ie the first value of the list. So Iīm thinking the selected... events isnīt working. Do you know what Iīm doing wrong?

Web Forms :: Trigger Postback From Code C#?
Nov 9, 2010I am trying to write some code where it sets the imageUrl of an ASP Image from the codebehind (on a timer), but it does not change it on my screen (its changing in debug view). I assume this is because I need to postback everytime I change the image. Problem is, I cant trigger the postback from CodeBehind so that it will change. How do I do that?

LoginStatus Inside LoginView Doesn't Trigger LoggingOut Event?
Aug 11, 2010I have a LoginView in my APS.NET application with AnonymousTemplate and LoggedInTemplate. I've put LoginStatus control inside LoggedInTemplate but it doesn't work as expected.
Here's the code
<asp:LoginView ID="LoginView1" runat="server">
<AnonymousTemplate>
<asp:Login ID="Login1" runat="server" OnAuthenticate="Login1_Authenticate"
DisplayRememberMe="False" PasswordRecoveryUrl="/"
DestinationPageUrl="/">
</asp:Login>
</AnonymousTemplate>
<LoggedInTemplate>
You are logged in as
<asp:LoginName ID="LoginName1" runat="Server"></asp:LoginName>.
<asp:LoginStatus ID="LoginStatus1" runat="server" LogoutAction="Redirect"
LogoutPageUrl="/" onloggingout="LoginStatus1_LoggingOut" />
</LoggedInTemplate>
</asp:LoginView>
All event handlers are correctly defined in code behind file.
The problem is that if user logs in he will see his user name with logout link from LoginStatus control. Clicking the logout link takes the user back to login form (both login and logout form are part of the same user control) but if I refresh the page the user is still logged in.
I've noticed that if I move LoginStatus control outside the LoginView then logout process works as expected. I've also noticed that when LoginStatus is inside LoginView then it doesn't raise a loggingout event.

Web Forms :: GridView Update And Delete Command Button Doesn't Trigger
Apr 3, 2010I have 3 gridviews in one of my web page. I have simplified the system structure in the image below(further description will be stated below the image): As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews. During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
The data in the returned datatable will be filetered by type using RowFilter method and stored into the 3 dataviews. Each dataview will act as the datasource for the 3 GridViews respectively, and therefore I specified the datasource programatically instead of setting the datasourceid for each gridview.
dataview1 = New DataView(dtSelectedTable)
dataview1.RowFilter = "Type='1'"
GridView1.DataSource = dataview1
GridView1.DataBind()
dataview2 = New DataView(dtSelectedTable)
dataview2.RowFilter = "Type='2'"
GridView2.DataSource = dataview2
GridView2.DataBind()
dataview3 = New DataView(dtSelectedTable)
dataview3.RowFilter = "Type='3'"
GridView2.DataSource = dataview3
GridView2.DataBind()
However, the Update(command button) and Delete(template field) doesn't work, the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource. I couldn't figure out why, hope that someone who have come across the same problem couldn't provide some guidance.
JQuery Form Submit Handler Doesn't Trigger When TextField Changes By Watin In MVC App?
Aug 20, 2010I am writing Watin test in MVC Asp.net app. I mvc app, all input are wrpped with form and every time an input or textarea is changed their form gets submitted by jquery like code below:
$("textarea", context).change(function() {
$(this).parents('form:first').submit();
});
This is perfect when changes are done by keyboard. However this doesn't trigger the form submit when input/textarea are changed by Watin TypeText() method. I tried to call Change() and Blur() events by Watin and also tried PressTab() with no luck.
