I develop a custom data pager control. Its "previous" and "next" hyperlinks buttons don't work properly and I don't understand why.

I'm customizing a NopCommerce store, and am using a gridview to display and sort the products. All that works well. I like how the external pager (user control) works with the gridview, with one exception -- it uses the hyperlink control, so I lost viewstate, which I need to retain for both the search page and to retain the gridview sort options. Based on the page selected (from the pager control), I query the database and rebind the gridview. So, I switched the user control to use LinkButtons instead of Hyperlinks. This is the sample code for one of the buttons:
[Code]....
I set a breakpoint inside the lbCommandClick method, but it never gets hit. Reading other posts tells me that I would have to add the dynamic controls in the OnLoad method, but since this all happens based on other data on the page (say search results), I don't think I can do it onLoad. However, the link buttons do work to cause a postback, and my viewstate is saved correctly. The only problem is that I do not know which button was clicked. I could check Request.Params["__EVENTTARGET"] onLoad, but that is kind of a hack -- I'd much rather be able to set the event handler in the user control and use the CommandArgument property. But, what I have tried so far fails.
Especially one that would allow me to set the EventHandler in the User Control? (e.g. OnlbCommand="PagerLBPageChange" )
I have a custom control which is rendered as a hyperlink:
Public Class TestControl
Inherits System.Web.UI.WebControls.WebControl
Implements IPostBackEventHandler
Public Sub RaisePostBackEvent(ByVal eventArgument As String) Implements System.Web.UI.IPostBackEventHandler.RaisePostBackEvent
Trace.WriteLine("Hyperlink 1 clicked")
End Sub
Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
writer.WriteLine("<a href=""{0}"" id=""{1}"">Hyperlink 1</a>", _
Page.ClientScript.GetPostBackClientHyperlink(Me, "Hyperlink 1"), _
Me.ClientID)
End Sub
End Class
This works fine. It also works nicely when put inside an UpdatePanel: Only the UpdatePanel is refreshed, no full postback is performed.
Now I would like to output a second hyperlink in the Render method. If I use the same id (Me.ClientID), everything works nicely, but this obviously results in broken HTML (no two controls are allows to have the same id attribute). If I use different client IDs (like Me.ClientID & "_1" and Me.ClientID & "_2"), a full postback is performed when the hyperlinks are clicked.
Is there some way to tell ASP.NET AJAX: "All postbacks of the following client IDs should be done asynchronously: ..."?
I'd like to implement a custom paging template for my formview that displays numeric paging as well as next/previous buttons. The pre-defined templates only appear to have numeric first last as an option. Can anyone recommend a good article that covers this?

I have datalist in my page and I use pagination for my data list:
private void GetCustomersPageWise(int pageIndex) {
if (Request.QueryString["H_name"] != "all") {
string BehCode = "";
using (SqlCommand cmd = new SqlCommand("GetCustomersPageWise1", _cn)) {
if (!(Request.QueryString["H_name"] == null)) {
BehCode = Request.QueryString["H_name"];
[Code] ....
Ok this pagination is like below :
<< next 1 2 3 4 5 6 7 8 9 10 Â Previuos >>
It show all pages. I want datalist pagination be like below :
<< Next 1 2 3 4 ... Previous >>Â
And when i click on 4 it change like below :
<< Next ... 5 6 7 8 9 10 Previous >>
Or some thing like that I mean I want some Pagination that doesn't show all pages. How I can do it?
URL... I'm trying this approach and I like it, It is what i was finding. customize the function he wrote to populate the pager control:Â
private void PopulatePager(int recordCount, int currentPage)
{
double dblPageCount = (double)((decimal)recordCount / Convert.ToDecimal(PageSize));
int pageCount = (int)Math.Ceiling(dblPageCount);
List<ListItem> pages = new List<ListItem>();
if (pageCount > 0)

I need the paginator is something like that:<FIRST><BACK>1,2,3....N<NEXT><LAST>where first return back to first page, back go to previous current page, next for next page and last jump to last page.How can I do that?
I have a pager template in a formview which shows the Prev, Next button and the number of pages. I want to make the Prev or the Next button disable when there are no more pages to go. Like, if it is the first page, then the Prev button will be disabled.

Mode="NextPreviousFirstLast"

I am a complete noob to ASP.NET (C# based) and have migrated from PHP (I have mentioned this a few times but I feel I have to 'cos some of the questions I ask seem so basic!)
I have page (Products.aspx) it has a grid view using products from the northwind DB, the grid view is paged to show 'n' products at a time and has an extra column which is basically a 'view this product' hyper link, the user can click on this link and is taken to another page (Product.aspx) which provides complete details for that particular product, so, this is what I want to do next, I want to add a button that takes the product ID, (or other unique property of the product - it doesnt really matter at the moment, but i am likely to stick to ID).
Then take that value and place it in a cookie, (I know that session variables are held in cookies, that is not really a problem at the moment, I am concentrating on basics, then I will go a little more advanced).
so, I have a button - call it productIdBtn, and its value, which is going to be the product ID, in the button on click handler, how would I add this value to a cookie - call it prodIdCookie?
I am having to re-learn everything from the ground up and because PHP is so simple to write (mainly because of its weak typing),
Got a problem that I spent all last night working on and still couldn't get it. I create this table dynamically. Then I have a text box and a button. You enter the name of a table in the text box and then click the button and that will call the MSSQL server and load the corresponding table. That works fine no problem.
Then I decided to create another table that lists the tables that are on the SQL server and create a hyperlink on each name of the table. So now all the user has to do is click the name of the table save the name of the table they clicked in the querystring and it will call the same procedure as the button. I'm getting a Findcontrol error that's telling me that two id's have the same id's when I click the hyperlink and then try to load through the button. It's duplicating the controls. I've tried clearing the viewstate, and session states and that still doesn't work. Has something to do with how hyperllinks and buttons work.
why my upload control will not work properly when placed inside an ajax tab control? If I place it outside the tab control everything works great.Here is what I'm trying.

I am having issue with cache-control. I have one IIS website with multiple host headers. When you browse site number 1 then cache will be set for this site, when you open browser again and go to 2nd site you will see content from first site. How can I determine cache content based on the site user visits? Everything working fine when you have 1 site and host header related to SAME site.
//Set Cacheability
if (!Context.User.Identity.IsAuthenticated && _activeNode.CacheDuration > 0)
{
var eTag = GetETag(_activeNode);
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.Public);

Can the page numbers (clickable) at the bottom of a gridview pager be accessed programmatically as buttons?asp.net 3.0 c#
View 1 RepliesI have developed a ASP.Net Server custom control in C# for 3.5. named "myCheckBoxList" inherited from CheckBoxList web control. Working is very simple. It just works as a two option buttons. I have taken a CheckBoxList which will show two fixed checkboxes always. When I check one checkbox then another will uncheck as vise versa. This control works perfectly only when I have placed only one instance of that control on web page. If I place more than one instance of control then it doesnt works.
I need solution from expert minds from developers as stackoverflow users.
The First - LblTextBox:
A label and textbox that have a LabelText field that can be set to change the label text
The Second - LoginCtl:
A login control that has two instances of LblTextBox for user name, password and a submit button
I want to control the tag rendering of these controls for formatting so I am not overriding CreateChildControls() to get the job done.
My issue is that the controls are rendered but none of the OnInit() code in either controls takes hold (blank labels, css styles not applied, etc..).

View 1 RepliesI have a Custom Repeater control that inherits from Repeater and has paging functionality, however when I click the next page button the first time it refreshes the control but does not change the page, if I click it again after that it changes page perfectly. I know what the issue is, when I click the next button it does a postback, then the data is bound to the repeater, and then after that the NextButton Event is handled.
Is there any way I can change the order of the page load events?? Or force the repeater to reload again after the event is handled?? I've included my Custom Repeater class bellow:
using System.Web.UI.WebControls;
using System.Web.UI;
using System.Data;
using System.Collections;
using System;
namespace ASPresentation.Controls
{
[ToolboxData("<cc:PagedRepeater runat=server></cc:PagedRepeater>")]
public class PagedRepeater : Repeater
{
public int PageSize { get; set; }
public int CurrentPageIndex
{
get
{
return Convert.ToInt16(Page.Session["ProjectIndex"]);
}
set
{
Page.Session.Add("ProjectIndex", value);
}
}
public PagedDataSource pagedData = new PagedDataSource();
LinkButton NextBtn = new LinkButton();
LinkButton PrevBtn = new LinkButton();
public bool IsLastPage
{
get
{
return pagedData.IsLastPage;
}
}
public bool IsFirstPage
{
get
{
return pagedData.IsFirstPage;
}
}
public override object DataSource
{
get
{
return base.DataSource;
}
set
{
pagedData.DataSource = (IEnumerable)value;
}
}
protected void NextButtonClick(object sender, EventArgs e)
{
if (!IsLastPage)
{
CurrentPageIndex++;
}
}
protected void PrevButtonClick(object sender, EventArgs e)
{
if (!IsFirstPage)
{
CurrentPageIndex--;
}
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
NextBtn.Text = "Next";
PrevBtn.Text = "Prev";
NextBtn.Click += new EventHandler(NextButtonClick);
PrevBtn.Click += new EventHandler(PrevButtonClick);
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
base.Controls.Add(PrevBtn);
base.Controls.Add(NextBtn);
}
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
}
public override void DataBind()
{
pagedData.AllowPaging = true;
pagedData.PageSize = PageSize;
pagedData.CurrentPageIndex = CurrentPageIndex;
base.DataSource = pagedData;
base.DataBind();
}
}

I am using buttons for paging in my gridview, but they will not center
[Code]....
and the CSS also has text-align:center , but they still hang left.
I have 2 button links and 1 text like this:
Previous JULY Next
Every time i press Previous, a variable mymonth subtracts 1 , and when if i press
Next , the variable mymonth adds 1.
Previous LINK: <%# mymonth - 1 %>
Next LINK: <%# mymonth + 1 %>
All the schedule from the DB is shown, using the following SQL:
SELECT DISTINCT day(mydate) FROM schedule WHERE month(mydate)=" + mymonth + " AND year(mydate)=" + myyear + " ORDER BY day(mydate) ASC"
But my problems are:
- i want to show 3 months backwards from th actual month
- when mymonth is 1 (January) 2011 for example, it would show December, November and October from 2010
- If for example, we are in JULY, it would show until APRIL backwards, and when on APRIL it wouldnt show the PREVIOUS button.
I have a wizard that has 3 steps
1 - add property
2- add address
3- add room
on the third step I would like to add a button next to the next/previous buttons that would allow the user to add another room.Is there a way to add a button to the wizard and then handle its onclick event
I have a problem, i have a gridview populated with items and in the pager i have controls for previous and next and a dropdownlist that shows the total number of pages. I also have a search function to search for item.
if i for exemple search for *egg* i get a number of results and the ddl is populated with total number of pages for the searchterm. but if i click on the button for "next" the search result disapear and i get all the pages back (because of the postback) but how do i do to keep the state of the ´search so that i can use the next and previous buttons and the ddl listing of pages, depending on the search?
I have a question about using a linkbutton. I have 5 link buttons. One is a DayLink, MonthLink, WeekLink. One PreviousLink and One NextLink. How can I get the previous and next buttons to correspond with what page I am on. So say I am looking at the calendar in days. And I'm on Thursday 2/18/10, and I want that next link button to go to Friday 2/19/10. But also need it to go to the next week or month, depending on how i'm looking at the calender. So I need one linkbutton to be able to do multiple steps.
