I have a page that has a button that causes a post back, however, once the post back is finished, the url now basically has my entire javascript file appended to the end of it. This is definitely a result ASP.NET's button control as I've tested it using normal buttons. What can I do resolve this?
Example:
Normal url:[URL]

've created 2 asp:listbox... asp:ListboxFrom and asp:ListboxTo. When I double click on the item on ListboxFrom it moves (appends) the item to ListboxTo... So everything works fine till here. But when I click on the submit button to process everything I don't get the selected items in my code-behind for the listboxes. I debugged on Page_Init and Page_load but it restores the default controlstate values..
1) How can I get the values in code-behind ? so the state of asp:listbox as it is added client-side code.
2) another question: when it appends to the ListboxTo the items are selected per default (they are blue). How can I avoid this?
below is the simple JQuery code I use in aspx,
<asp:ListBox ID="listboxFrom" SelectionMode="Multiple" />
<asp:ListBox ID="listboxTo" SelectionMode="Multiple" />
$(function() {
$('select[id$=dnn_ctr658_ViewAgenda_Invoer_listboxFrom]').bind("dblclick", function() {
$("select[id$=dnn_ctr658_ViewAgenda_Invoer_listboxFrom] option:selected").appendTo("#dnn_ctr658_ViewAgenda_Invoer_listboxTo");
});
$('select[id$=dnn_ctr658_ViewAgenda_Invoer_listboxTo]').bind("dblclick", function() {
$("select[id$=dnn_ctr658_ViewAgenda_Invoer_listboxTo] option:selected").appendTo("#dnn_ctr658_ViewAgenda_Invoer_listboxFrom");
});
});
On my page: a Button1, a ListView1, a Panel1 and inside Panel1 an ImageButton1In the ListView1_PreRender-Event the property Panel1.Visible = false or Panel1.Visible = true is set.1. After first loading of the Page Panel.Visible = false ist set in ListView1_PreRender.2. After the postback click on Button1 the criteria for the visibility of Panel1 are evaluated, thus setting in the ListView_PreRender Panel.Visible = true.
View 3 RepliesI 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"

I have 2 textboxes and a submit button inside a .net composite server control. I tried to only postback when submit button is clicked. I set autopostback = false for both textboxes. But either one still trigger submit button's onclick event by hitting "Enter" inside textbox. How can I stop postback by enter key?

iam using the Jquery Uframe with asp.net project.Iam getting a postback problem here.
In side the uframe ,button control getting postback the page even the client side method call also.
i tried with the Html button Control also by setting the type="submit" ,iam facing the same problem.
And I got very limited reference about the uframe(codeflex,codeProject).
Is something like this possible?
Dim iCounter as Integer
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1
//then trigger a full postback
Next
End Sub
I am new to the concept and feel like there must be something really easy that I am missing.
On postback, how can I check which control cause postback in Page_Init event.
protected void Page_Init(object sender, EventArgs e)
{
//need to check here which control cause postback?
}
Anyone with similar conclusion? GridView does not databind/refresh upon postback unless the postback is called by itself?
View 1 RepliesI implemented the AsyncFileUpload control on a web page. This web page requires uploaded files to appear in a gridview. The gridview contains the following columns: "File Name", "Confidential" Check Box, and a "Remove" button to remove the uploaded file.
Since the AsyncFileUpload postback does not do a full page postback, I need to "force" a postback on the OnClientUploadComplete event of the AsyncFileUpload control in order to render the gridview after uploading a file. In the OnClientUploadCompleteevent, I use javascript to call __doPostBack. In this postback, I only bind my gridview and display the file information (I don't re-save the file).
The problem: On the AsyncFileUpload's first "partial" postback, the file is successfully uploaded, as expected. On the second postback that I force with __doPostBack, the file is re-uploaded. You can verify this by using Google Chrome, which displays the upload progress. The behaviour is as follows: After selecting the file, the progress increments from 0% to 100% and the file is uploaded. After this, the __doPostBack executes, and you can see the upload progress increment again from 0% to 100%.
How can I make sure the Gridview is properly populated, but that the file is not uploaded twice?
