CrossPagePostBack to get the information from the search and showing it in another page with the gridview.The problem is that when I want to search in the target page the crosspagepostback is still is fired and I do not want it to happens. I want the CrossPagePostBack to be executed jsut once . The code I am using is the following:

My aspx page is not showing latest data after reopen the page.. but after save data it shows latest information.
If I close the project and rerun the project then it shows latest data.
Interesting metter is the page_load event is not fired after thie page loaded once.
If I delete temporary internet files from tools-->internet option then the page reloaded.
I have a simple Insert Query and placed it at Page Load of my page, each time the page is loaded, it runs this INSERT COMMAND twice and inserts two rows to DATABASE.
I have also set the AutoEvenWireup to FALSE, but did not solve my problem.
Here is the Insert Command at the Page Load:

On Button click(postback), my dropdownlist of gridview is getting blank, so i m getting error of "Object Reference...." on the line "ddl.selecteditem.value"Also, dropdownlist's selectedindexchanged event is fired on Button Click(Page Postback), which is making the dropdownlist to go blank. AutoPostBack of dropdownlist is set as False,
View 8 RepliesSo I have a GridView control with autogenerated column set to true, it also has autogenerated Edit and Delete buttons, sorting and paging, and also I am binding this same gridview to multiple data sources at runtime. All is working well.
Now I am adding a dynamically generated footer row at runtime. This footer row will allow users to add new record regardless which data source it binds to. So it is working as well except there's a small bug I couldn't figure out why. It's when I navigate to the last page of the gridview, if the rows on the last page is less than the page size, for example, I have page size 10 and the rows in last page is 9, then when I click the 'Add' linkbutton, the Add event does not fire, instead, it fill the last page with additional blank rows, that means if the last page has 5 rows, it will fill 5 blank rows below, if it has 9 rows, it will fill 1 blank row below. Then if you click the add again, it will work. If the last page already has 10 rows then, it works just fine.
Below is the code I used to dynamically add footer row:
[Code]....
I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event.
The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
protected void Page_Load(object sender, EventArgs e) {
LoadGrid();
}
But this is very expensive and causes that the db request will be executed twice. If I changed the code to what I want:
protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack)
loadGrid();
}
I get no CheckedChanged event.
Is there a possibility to get:
- Adding a Checkbox in RowDataBound
- Only "LoadGrid()" if it is no PostBack
- Getting the CheckedChanged event of the relevant row

I have a confusion regarding ajax call.when an ajax call is done why is it so that a page load event is fired when its not a ful page request.
My understanding is that a page load event should not be called on an asynchronous postback.
Can any1 explain me why this is happening?
here is the code:

I have an update panel on the parent page into which I load and remove a set of user controls.
Now, when a button is pressed on the user control, the events are fired but there are no changes in the page. For example:
Main Page
<updatePanelMain>
<childcontrol1>
<childcontrol2>
etc
ChildControl.ascx
<update panel 1>
<panel1/>
<panel2/>
<btn1/>
etc
So, if I want to hide panel 1 when btn1 is clicked etc, I simple use code such as panel1.visible = false.
All this gets executed but nothing happens to the page.
<asp:UpdatePanel ChildrenAsTriggers="false" UpdateMode="Conditional" ID="updatePanel"
runat="server" EnableViewState="true">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
<ContentTemplate>
However, when I use placeholders instead of update panels in the child controls, I dont face any such problems.
<asp:PlaceHolder ID="placeholderTypeOfInvestor" runat="server">

A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??
In my current web application I have a listbox containing large number of elements. I have used an ajax listsearchextender to help the users in selecting the elements. I have set the autopostback property of listbox true. The application is working fine as expected in internet explorer. But in firefox while I am typing some text in search lable of listsearchextender the selectedIndexChanged event is fired and the page is posted back. So I am not able to selected the item properly using list search extender control. Can you please suggest me how can I stop the selectedIndexChanged event.

I put debugger into LinkButton1_Click event of user control but it never goes there.
i was debugging a test page when i noticed that its init and load event handlers are being called twice.
i found out by search that this may arise due to some html tags which im not using in my page,
also some line:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load,Me.Load
may cause this problem.
i use c# in the code behind aspx, if such line is the problem, in which file should i look for?
