I am using a Listview and Datapager control. But when I refresh the page it always set the datapager to page 1. I want that it should be in the same page after refreshing. For example I want the same functionality as stackoverflow is having like: http://stackoverflow.com/questions/tagged/datapager. How to do this can any one help.

DataTable dt = new DataTable();
DataList1.DataSource = dt;
DataList1.DataBind();
DataList2.DataSource = dt;
DataList2.DataBind();

[code]....
There is two checkbox group which have same datasource, so in both case same checkbox are showing and also same event is firing for both. Here is the event code
protected void CheckBox_CheckedChanged(object sender, EventArgs e)
{
string OpService = ((CheckBox)sender).Text;
}
Now what i want to do is, while check one checkbox from the 1st checkbox group the same checkbox should be selected from the second checkbox group automatically, also if i deselect one checkbox that should be deselect from both checkbox group.

I have a ListView that I am paging with a DataPager. I would like to set the initial page of the pager on Page_Load. I have tried the DataPager.SetPageProperties method but it's not doing what I need. Here's how I'm calling this method: dataPager.SetPageProperties(3, dataPager.TotalRowCount, false);
The line above trims the datasource to start at the third item and paging still starts at 1. This is not what I want. I want to keep the entire list of items and just jump to a specific page in the list. Is there another Property and/or method of a DataPager and/or ListView that I should use?

I am using a datapager on a page where different images are shown. Now i am using the following code:-
PHP Code:
<asp:DataPager ID="DataPager1" runat="server"
PagedControlID="lvPhotoViewer" PageSize="1"
onprerender="DataPager1_PreRender">
<Fields>
<asp:NextPreviousPagerField ButtonType="Link"
PreviousPageText="<< Previous" NextPageText="Next >>"/>
</Fields>
</asp:DataPager>
Now this code does run through all the images, but i need to alter the querystring and make it change to match the ID of the photo displayed. I tried adding QueryStringField="String" but this was hopeless.
I have a querystring like so:-
Quote:
[URL]
When i click on next image i need it to change to something like:-
Quote:
[URL]
See the PhotoID has changed. But it currently does not do this. When i arrive on the page the PhotoID stays the same. I have been trying for a while and im starting to give up!
So was wondering if there was an alternative.

I am really fed up with a datapager I am using as I cant change the value of the querystring. I currently have this code:-
[Code]....
When I first arrive on the page I see this querystring, depending on the picture selected a different ID will be shown:- [URL]
See the bold. When I click on the next image I need the querystring to change to the ID of the image. So something like. But it does not work, I don't know to do it. I tried with adding QueryStringField="String" but this didn't work either.

I have a datapager with next and previous buttons as so:
<asp:DataPager ID="dpFeaturedPager" PagedControlID="lvFeaturedTips" QueryStringField="ftpg" PageSize="1" runat="server">
<Fields>
<asp:nextpreviouspagerfield ButtonCssClass="featured-previous" PreviousPageText="Previous" ShowNextPageButton="false" />
<asp:nextpreviouspagerfield ButtonCssClass="featured-next" NextPageText="Next" ShowPreviousPageButton="false" />
</Fields>
</asp:DataPager>
When there is only one page available, the Next and Previous links are rendered as so: <a disabled="disabled">Previous</a> I have not seen this disabled tag before, and presume it's coming from the datapager control which I won't be able to control. As usual, this is fine on FireFox but on IE7 the Previous and Next text does not render correctly - it is outlined (what I would expect disabled to look like to be honest - but looks a bit ugly in the page!)

I am using ListView/DataPager.
For performance reasons I page my results at database, using ROW_NUMBER(SQl2005).
At my C# code just comes one page at time. How can I say to DataPager that I have more rows that really are at my List?

I've just taken my first stab at making a ListView, ObjectDataSource, and DataPager run in an AJAX panel.
I had trouble getting it to work until I removed the QueryStringField="page" attribute from the DataPager. This attribute causes the current page to be passed as a query argument in the URL. For obvious reasons, I guess that won't work when posting back using AJAX.
Now my question is if this hurts my SEO. When I used QueryStringField, the page links appeared as regular links with various query arguments. But now the links are just javascript. Haven't I hurt a search engine's ability to scan related pages?

how do I use the datalist "DL_Pro_Result" to find the child datalist "DL_Gro_Result" in C#?
For example in the following code, dlii value is null, even though dli != null.
DataList dli = (DataList)Page.FindControl("DL_Pro_Result");
DataList dlii = (DataList)dli.FindControl("DL_Gro_Result");
<div id="ProList">
<asp:DataList ID="DL_Pro_Result" runat="server">
<HeaderTemplate>
<table id="T_Pro_Result_Header" runat="server">
<tr>
<td>
<asp:Label ID="L_Pro_Result_Header" runat="server"></asp:Label>
</td>
</tr>
</table>
</HeaderTemplate>
<ItemTemplate>
<table id="T_Pro_Result_Item" class="table" runat="server">
<tr>
<td>
<asp:Label ID="L_Pro_Result_Item" runat="server"></asp:Label>
<asp:Button ID="B_Pro_Result_Item_1" OnClick="B_Pro_Result_Item_1_Click"/>
</td>
</tr>
<tr>

How to accomplish this, The problem is how to attach the button control with values related in that partucular row, Note that I am using ArrayList as the Datasource since I am enabling pading via pageDataSource class...

I have a strange problem that I don't understand about DataPager. After changing the page set (pages 6 - 10 for example), and clicking on a page (6, 7, 8, 9 or 10), it will displa to the first set of pages counting from 1 again.
Let me explain. I have a ASP.Net page with Listview and DataPager.
<asp:ListView ... DataSourceId="EntityDataSource" DataKeyNames="id">
<LayoutTemplate>
<asp:DataPager runat="server" ID="DataPager1" PageSize="15">
<Fields>
[Code].....
All this works, but the problem is that the set of pages will not remember during postbacks. Let me explain this.
By first request of page, the pages show:
<< 1 2 3 4 5 ... >>
By clicking the ..., the next set of pages will be displayed (and also the data of page 6 will be displayed)
<< ... 6 7 8 9 10 ... >>
But when I click on page 7 to 10, the pages text will display the first set of pages 1-5.
