Mar 10, 2011I have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an
error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"

View 11 RepliesPurpose Of EnableEventValidation - Working?
Oct 11, 2010<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" onrowediting="GridView1_RowEditing">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="btnEdit" runat="server" Text="Edit" CommandName="Edit" />
<asp:Label ID="lblFirstColumn" runat="server" Text='<%# Eval("FirstColumn") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:Label ID="lblEditMode" runat="server" Text="This is Edit mode"></asp:Label>
</EditItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("FirstColumn", typeof(int));
dt.Rows.Add(100);
GridView1.DataSource = dt;
if (!IsPostBack)
GridView1.DataBind();
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
GridView1.DataBind();
}
If I change if (!IsPostBack) GridView1.DataBind(); to GridView1.DataBind(); and try to put GridView into Edit mode by clicking btnEdit, then I get the exception: Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. But if I set EnableEventValidation to false, then GridView1 won't enter edit mode ( ie - GridView1_RowEditing doesn't get called ). BTW - same problem also occurs with other databound controls ( DataList, DetailsView ) Page. EnableEventValidation gets or sets a value indicating whether the page validates postback and callback events. When the ableEventValidation property is set to true, ASP.NET validates that a control event originated from the user interface that was rendered by that control. A control registers its events during rendering and then validates the events during postback or callback handling.
a) Why must postback and callback events be evaluated? and how exactly does evaluation happen?
b) Why would calling GridView1.Databind() on each postback cause exception when trying to put it into edit mode?
c) I also don't see any reasons why disabling EnableEventValidation prevents GridView from entering edit mode?! Thus why did.

AJAX :: UpdatePanel: What Is The Purpose Of PostBackTrigger
Jul 24, 2010In documentation I have read:
„Use the PostBackTrigger control to enable controls inside an UpdatePanel to cause a postback instead of performing an asynchronous postback."
I made simple application and I do not see difference between using PostBackTrigger and standard postback.
I have three buttons: two inside update panel and one outside update panel. When I click btnUpdateAsync in event handler I set text property of lblUpdatePanel and lblNoUpdatePanel and only lbl that is inside update panel is chaned if web browswer - so this is ok.
Whant I click btnUpdateInUpdatePanelSync all page is refreshed and both lablels are changed in web browser.
When I click btnUpdateOutsideUpdatePanel I see the same behavior.
If I used button that is not associated with PostBackTrigger I would get the same behavior - so what is the purpose of PostBackTrigger?
This is my app:
[Code]....
protected void Page_Load(object sender, EventArgs e)
{
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
}
protected void btnUpdateAsync_Click(object sender, EventArgs e)
{
lblUpdatePanel.Text = "btnUpdateAsync_Click";
lblNoUpdatePanel.Text = "btnUpdateAsync_Click";
}
protected void btnUpdateInUpdatePanelSync_Click(object sender, EventArgs e)
{
lblUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
lblNoUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
}
protected void btnUpdateOutsideUpdatePanel_Click(object sender, EventArgs e)
{
lblUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
lblNoUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
}

View 3 RepliesWeb Forms :: Postback Event Handling?
Oct 5, 2010According toMSDN[URL]Postback event handling:If the request is a postback, control event handlers are called. After that, the Validate method of all validator controls is called, which sets the IsValid property of individual validator controls and of the page."It is my understanding that the Validate method of the validtor controls is called after Load but before the control event handlers.The text quoted says its after the control event handlers.

View 5 RepliesC# - How To Track Event From Previous Postback
Jan 24, 2011I have a requirement to check for a certain condition on postback before redirecting (Response.Redirect) to another page.
Note... I cannot use JavaScript to detect whether or not to confirm (this is also a requirement) :s
Pseudo:
[code]....
If the showConfrim flag == true, then the client will be show a modal dialog box asking them if they are sure they want to redirect. If the user clicks on "Yes", then the page posts back and the desired effect is that the lbtnRedirect_OnClick event is fired. How would I about tracking the lbtnRedirect event?
Edit:
I have no problem tracking the flag to show the modal (yes JS must be used to show the modal... somethings you just cannot get rid of :)). I should have been more clear.
It is when the user clicks "Yes" to continue the redirect. The page will postback again but needs to know which event to go through.
i.e. Suppose there are 3 onclick events, 1) lbtnRedirect1_Onclick 2) lbtnRedirect2_OnClick 3) lbtnRedirect3_OnClick... each of which does the confirm check.
Each onclick event does the check. So when the user clicks on "Yes" on the modal, how does the page know which event to drop back into?
How To Get The Postback Argument From InitializeRequest Event
Dec 10, 2010I capture the initializeRequest AJAX event using Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(InitializePostback).
Inside the InitializePostback function, I can successfully get the item that triggered the postback by calling args.get_postBackElement(), but this is not enough info for me, I also need to get the postback argument that was sent with the postback. How can I do this?
MVC :: How To Determine Which Event Caused The Postback
May 13, 2010Currently I have two events in my view that can trigger the post back (A dropdownlist and a submit button).
1. <%= Html.DropDownList("List", ViewData["Days"] as SelectList, "--Choose Day--", new { onchange = "this.form.submit();" })%>
2. <input type="submit" value="Submit"/>
When either of these are used, it they both call the [AcceptVerbs(HttpVerbs.Post)] Index() method.
What I want to know is how can I know which event caused the postback, because I need to process each one differently.
