Hi,
You can use frames for that purpose.

Thanks Apurva...but i heard about something called 'scriptcallback'. this technique helps to update a single control on the page without full page reload. I have used 'scriptcallback' but only for html controls and not for asp.net server controls. Any idea?

Hi Ashuu,
Actually i don't have much idea on using scriptcallback for server side controls. But you can also tryout xmlhttp.

hope this will be helpful to you.

Hi
I am using C# and ASP.Net through Visual Studio to develope a Web Application.
I have a DataList that I databind to a DataTable called categoryTable. The categoryTable was loaded from the database and contains a CategoryIndex column and a CategoryName column.
DataList_Categories.DataSource = categoryTable;
DataList_Categories.DataBind();
The DataList contains a LinkButton in each row on which I display the CategoryName:
<ItemTemplate>
<asp:LinkButton CommandName="select" Text='<%# DataBinder.Eval (Container, "DataItem.CategoryName")%>' runat="server">
</asp:LinkButton>
</ItemTemplate>
When I select an item in the DataList I want to get the CategoryIndex from the selected row and load the appropriate products to display them in another DataList. How do I get that information (CategoryIndex) out of the DataListItem?
private void DataList_Categories_ItemCommand(object source, System.Web.UI.WebControls.DataListCommandEventArgs e)
{
if (e.CommandName == "select")
{
int index = e.Item.ItemIndex;
DataListItem item = DataList_Categories.Items[index];
}
}
Thanks

Hi Kobus,
Pass that as command argument from the html side and then use it in the code behind side like e.commandargument.

Hi apurva kaushal
Thank you for the reply. On one of the other websites I am still waiting for responses to some of my questions. I shall play a bit with e.commandargument and see what I can come up with.

In the HTML code of the page you can determine the index in the CommandArgument attribute:
<itemtemplate>
<asp:linkbutton commandname="select" commandargument="<%#Container.ItemIndex%>" text="<%# DataBinder.Eval(Container, "DataItem.CategoryName")%>" runat="server">
in the code-behind page:
private void DataList_Categories_ItemCommand(object source, System.Web.UI.WebControls.DataListCommandEventArgs e)
{
if (e.CommandName == "select")
{ int index =Convert.ToInt32(e.CommandArgument);
}
}
Then you can send the index value to the other DataList(reload the same page or go to another page that contains the DataList) through a query string :
Response.Redirect("page.aspx?index="+selectedindex);
Then you can get the query string in the page that you were redirected to:
int categoryIndex=Convert.ToInt32(Request.QueryString["index"]);
But i think you should send a CategoryID field value instead of the index that points to the DataGrid item which could be changed.

Hi TheEagle
Thanks for the quick reply, On another website I wait forever and no-one responds to questions. Your HTML code did not come up in the reply. Could you let me have that again please?

Hi,
I’ve got a problem with my onclick handlers for command buttons
being dropped on page render for a popup window.
On the opening window, I have several command buttons,
and they all have the standard click handler references
(as they should):
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
input type="submit" name="button03" value="submit text"
onclick="WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions( ...
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
... and this isn’t present for command buttons on the popup page.
On the popup window, the standard click handler is not in the button tags
on the rendered page - and the only buttons that have onclick set
are the ones where I use the Attributes property to set the
button for my own JavaScript handlers:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
string fn_call="javascript:doPostBack_JS('Test','','zxc1');"
new_button.Attributes.Add ("onclick", fn_call);
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
... and THAT renders OK:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
input type="submit" name="Button04" value="JavaScript Submit"
onclick="javascript:doPostBack_JS('Test','','zxc1');"
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
I set up a simple test case on the popup window page:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
[script language="C#" runat=server>
void SubmitBtn_Click(Object sender, EventArgs e)
{
Message.Text="Hello World!!";
}
. . . . . . . . . . . . . . . . . . . . . . . . . . . .
[h3>Button Example[/h3>
Click on the submit button.
[asp:Button id="Button1"
Text="Submit"
OnClick="SubmitBtn_Click"
runat="server"/>
[asp:label id="Message" runat="server"/>
[/form>
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
... and this is what got sent to the client:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
[h3>Button Example [/h3>
Click on the submit button.
[input type="submit" name="Button1" value="Submit" id="Button1" />
[span id="Message"> [/span>
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
As should be obvious, onclick isn’t set on the rendered page.
The script source tags are present on BOTH the primary page,
AND the popup page:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
[script src="/Webfolder01/WebResource.axd?d=
[script src="/Webfolder01/WebResource.axd?d=
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
This is the JavaScript function that opens the popup window:
// =======================================================
function popup01 ()
{
var win_url
= "http://localhost/Webfolder01/CtrlInit12b.aspx";
var win_name
= "_blank";
var win_chrome
= "toolbar=0,scrollbars=1,location=1,statusbar=0,menubar=0,resizable=1";
var win_dimn
= ",width=444,height=444,left = 290,top = 162";
DBname_popup = window.open (win_url, win_name, win_chrome + win_dimn);
if (window.focus) {DBname_popup.focus()}
stop_postback = true;
}
// =======================================================
The really freaky thing about this is that it was working last week,
after I tested it - and it WAS working OK.
Does anyone have any idea as to why this is happening?
THANK YOU FOR YOUR ATTENTION TO THIS!!!

Hi,
So I have this problem, here it is.
I have a repeater with a check box in each itemtemplate. What I need is, to find all checked checkboxes (in the repeater) and send their respective "ID" properties back to the Invite(string ID) method on the server (my aspx.cs file).
Does anybody know how to do this ? I was trying to do it with javascript but I'm not good enough. I guess if somebody could just show me how, using javascript, to find all the seleted checkboxes in my repeater and getting their ID properties, (i.e. <%# DataBinder.Eval(Container.DataItem, "ID") %>), then I think i know how to post it back to the server us javascript.
Thanks.

Alex,
The way to access the checkbox with javascript in the repeater is similar to that in the datagrid control, you can see the site[^] for the sample script.
However, IMO you may not need to use javascript to access the checkbox in the RepeaterItem to get the id values, instead you can walk through the Repeater.Items[^] collection, and get reference to the checkbox control, you then can check if the checkbox is selected or not, and get the id value bound to it. And I think you may want to collect the ids of the checked checkboxes with javascript when you intend to use AJAX to do something.

HAHA,
I just discovered the Items property. This looks good !

|

|

so If I binded a class AdminPaper to the Repeater, I should be able to cast Items[i] in to an AdminPaper right?

Hi
Thanks a lot for solution. I am tried out for the same.
client.DownloadFile("http://132.186.90.79/RRM/SavedXML.xml","SavedXML.xml");
This works very fine if i run on the server itself, but when ran on client machine its not saving the file.
I seached the file in entire client machine, but could not find it.
I am generating XML file with fields entered by user and trying to provide a saved copy for the user.
Regards
Suma

My situation,I have two pages ,A.aspx and B.aspx. On A.aspx i have a datagrid to show informaton, each row of the datagrid consists of its own select button. when the button clicked, B.aspx will pop up. When the second time the user click another row's button on A.aspx( B.aspx window not close yet), the B.aspx will auto refresh at that time and show another information. For the 3rd time ,the B.aspx also auto refresh when the user click the another button on A.aspx and so on.
So , may i know how to code to allow the B.aspx will auto refresh when the user click the button on A.aspx? 
Thanks a lot.

I don't know if anyone will be able to help me, but I have a real strange error with c++ on Visual Studio on my XP. I have a code fragment:
if( !Directory::Exists(out1))
Directory::CreateDirectory(out1);
Exists compiles with no problem but CreateDirectory gives me the following error:
error C2039 'CreateDirectoryA' is not a member of 'System::IO:Directory'
When I put the cursor on CreateDirectory, it correctly identifies it as System::IO:CreateDirectory(System::String __gc*). Then when I compile Exists goes through OK, but CreateDirectory turns into the ANSI version of CreateDirectory which it then claims isn't part of the class (as it probably isn't). Who asked the compiler to turn CreateDirectory into CreateDirectoryA?
If anyone has any suggestions, I'd be very grateful.
Thanks,
Ilan

I found the problem in WinBase.h. It has
#ifdef UNICODE
#define CreateDirectory CreateDirectoryW
#else
#define CreateDirectory CreateDirectoryA
#endif // !UNICODE
I added #undef CreateDirectory and it now compiles.
