Web Forms :: Setting Page Index When Working With Multiple DataGrids On Page
Jul 18, 2012
I have 2 DataGrid in a single page.
First DataGrid contain 2 page and 10 records per page
Second DataGrid contain 5 page and 10 records per page
When i click 3rd page of second DataGridthe following error occur
"Invalid CurrentPageIndex value. It must be >= 0 and < the PageCount."
public partial class Admin_Over_all_report : System.Web.UI.Page {
Dataconnection dc = new Dataconnection();
protected void Page_Load(object sender, EventArgs e) {
if (IsPostBack == false) {
bind();
I've a gridview control that has paging enabled. The control works completely fine in IE. However I was shocked to learn that the same page is not working on firefox i.e when I click on a page index the grid doesn't show selected page's data!
The page is posted back when I click a page index, I've checked it in debug mode as well. However the code for "Page Index Changing" is never fired!
My purpose is to modified some data only for current page in a gridview. I call this function in page load and GridView_PageIndexChanged events. When it's called in page load event, it works fine. But when it's called in PageIndexChanged event, only the rows on the first page in GridView are looped through. For example, if I click page 5, the rowStartIndex becomes 100 = 5 x 20 (my pagesize). The if condition becomes itemsRead >= 100 andAlso itemsRead < 120. But after itemsRead is increased to 19, the For each gridViewRow loop stops and the if condition is never satisfied.
am creating a web application in using c# with asp.net.
in that am using login page only as normal aspx page. other pages are using masterpage.
when i click logout button in masterpage. page will redirect to login page. after that if i click browser back button it was moving to previous page. how can i prevent this.
am using this following code in master page aspx page. And My log out button code is below.
I have a gridview which is fairly straight forward... I've added paging to the gridview which functions correctly. However, after clicking any one of the page buttons (next page/last page), it appears some sort of a label is being displayed in my web form saying "NewPageIndex: 1". This changes from page to page displaying the actual index of the page. Why is this displaying? The only thing i can think of is the size of my gridview (Right now set to 1500 lines per page) . here is my gridview control html code:
but when I added the bar graph, the first chart appears but does not show the lines and the second graph is not displayed at all ... Is it possible to put 2 chart like that ?
I'm trying to get a page working using a tab container and multiple tabs. So, I created a new blank page and pointed it to my master page. The master page has two content panels within it.
I'm adding the tab container in the top conent holder, but when I go to view the page, I get an error. Below is the error followed by the code.
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

i have to use two different Ajaxfileupload controls in a page .But when i upload file through second control the second event doesnot get fired(UploadComplete) everytime first event is fired.
In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
I have a master page and set it's back ground color in the body tag <body style="background-color:Red">. Now that is fine for the Master page. How do I set the back ground color of the content page to a different color?
I have a page with features supplied from both a master page and a child master page.In the content placeholder for the head in both master pages I have supplied the link to the stylesheet for the site.In Design View in VS 2008 the CSS code seems to be functioning correctly.When viewing in a browser the CSS does not appear to be applied at all.
Here is the CSS code for the div elements within the main content placeholder:
I am receiving a Parser Error with all my pages in a particular folder:
Parser Error Message:
The file '/railroad/freightcars/covered_hopper/MasterFiles/Freightcars.master' does not exist. Line 1: <%@ Page Title="Freight Car Photos - CP Covered hoppers - CoveredHopperPhotos.com" Language="C#" MasterPageFile="~/MasterFiles/Freightcars.master" AutoEventWireup="true" CodeFile="cprail.aspx.cs" Inherits="railroad_freightcars_covered_hoppers_cprail" %>
It seems like the ~ is not resolving; none of my .aspx pages in this folder work. All my pages in several other folders work fine.
I had this problem with another folder when i first published pages to a folder named covered_hoppers. Since i couldn't figure out the problem, i renamed the folder to covered_hopper and re-published.. all worked fine for a couple of months until yesterday. Now i am having the same problem. No problems on my local copy; never had this error with any other folder in my site.
Im developing a website in asp.net where i want to connect the Payment gateway(rbs worldpay) as instructed im connecting to the payment gateway...the problem is, there im using some html button to connect the gate way as per the instructions the input button should be in form tag .in masterpage inherited aspx page we dont have any form tag the button is working properly when i placed that html code in content placeholder 1 but the button is displayed above the page......if i place that code in content place holder 2 the button is not working...........
I have a problem in setting the selected index /value in a drop down list. The list is bound by a Linq query and I want to add an item at the top of the list and set it as the selected item.
THis is the code i am using
ListItem li = new ListItem("Select", "", true); list.DataSource = (from ap in edc.Approvers where ! ap.approverEmail.Equals("") orderby ap.approverEmail select new {ap.approverEmail}).Distinct(); list.DataTextField = "approverEmail"; list.DataValueField = "approverEmail"; list.DataBind(); list.Items.Add(li); list.Items.FindByText("Select").Selected = true;
The listItem li is the item i want to be first in the list and also selected. Adding this before the databind just loses the item.
I have a datalist that holds imagebuttons which all link to images stored in a database. When I click on any of the image buttons the datalist enlarges the chosen picture and manages to dothis as the datalist is binded by the uniqueID of the image in the database. So, when I am looking at the enlarged picture, it would be nice to be able to click 'Next' & 'Prev' link buttons to move onto the next or previous picture without having to return to the datalist in between looking at a different photo.
I have managed to set up methods for clicking on 'next' and 'prev' linkbuttons that will successfully browse back and forth between photos in the datalist but the selected index always starts at 0, i.e the first photo in the datalist. So if I'm viewing the 5th image in the list and press 'next', the first image in the list shows up. I thought just by clicking on an image button would automatically set the selected index but obviously this is not the case. I have read various threads and tutorials on the net and a lot of them point to dlIcons.SelectedIndex = e.Item.ItemIndex; I have tried to put this in the itemDataBound method for my datalist but it changes nothing. And if i try to put that line of code in other messages in the class i get error messages (I'm using Visual Web Developer C#).
its part of a final year project due in 3 weeks and by now I should be writing the report! The code I'm using is pretty huge and spread out between classes but I will include what I think might help illustrate how it all works:
<asp:DataList ID="dlIcons" runat="server" DataKeyField="AttachmentID" OnItemDataBound="dlIcons_ItemDataBound" ItemStyle-BorderWidth="1px" RepeatColumns="5" RepeatDirection="Horizontal" CssClass="Icons" OnSelectedIndexChanged="dlIcons_SelectedIndexChanged"> <AlternatingItemStyle CssClass="AlternatingRowStyle" /> <ItemStyle CssClass="RowStyle" BorderWidth="1px" /> <HeaderStyle CssClass="HeadeBrStyle" /> <FooterStyle CssClass="FooterStyle" /> <SelectedItemStyle CssClass="SelectedRowStyle" /> <ItemTemplate> <asp:Label ID="lblFilename" runat="server" Font-Size="Small" Text='<%# Eval("Filename") %>' ></asp:Label> <br /> <asp:LinkButton runat="server" id="btnDelete" CommandArgument="<%# Bind('AttachmentID') %>" CommandName="DELETE" Text="Delete" OnClick="btnDelete_Click" Font-Size="small" CssClass="btnDelete" /> <br /> <asp:ImageButton runat="server" ID="imgBtnFileType" width="120" Height="120" ImageAlign="right" ImageUrl='<%#"http://localhost:49279/PDFViewer/GetAttachment.ashx?AttachmentID=" + Eval("AttachmentId") %>' OnClick="imgBtnFileType_Click" BorderWidth="1PX" CssClass="imgBtnFileType" CommandName="VIEW" CommandArgument="<%# Bind('AttachmentID') %>"/> <br /><br /> </ItemTemplate> </asp:DataList> The CS file: protected void dlIcons_ItemDataBound(object sender, DataListItemEventArgs e) { if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem)) { DataRowView drv = e.Item.DataItem as DataRowView; dlIcons.SelectedIndex = e.Item.ItemIndex; int attachmentID = (int)drv["AttachmentID"]; string fileType = (string)drv["Type"]; ImageButton imgBtnFileType = e.Item.FindControl("imgBtnFileType") as ImageButton; string fileName = (string)drv["FileName"]; Label lblFilename = e.Item.FindControl("lblFilename") as Label; lblFilename.Text = fileName.Length > 12 ? fileName.Substring(0, 10) + ".." : fileName; } } The next and prev link buttons onclick leads to these two methods: public int nextPic() { dlIcons.Items.Equals(dlIcons.SelectedIndex++); int nextAttach = (int)dlIcons.SelectedValue; return nextAttach; } public int prevPic() { dlIcons.Items.Equals(dlIcons.SelectedIndex--); int prevAttach = (int)dlIcons.SelectedValue; return prevAttach; }
these were void methods but i've been stuck on this for hours and have resorted to fiddling with just about everything.
I have a question. I will take the example exactly as it looks like. Below I have an .aspx page and a .cs page. In the .aspx page There is alot of text written.The .cs file as seen will in the Page_Load event redirect to another .aspx page which holds the real design to show for a user.(I only create these below .aspx page for google to find and index. These are content like Thread and posts but when someone enter this page, it will redirect to the real desinged page and now know what text to read in there.)
My question is if this .aspx page below can be crawled/red/index by search engines like google. (To mention is that I do use a sitemap).What worries me with this question is that I immediately redirect to another .aspx page.Does this prevent google from having the ability to read the below .aspx page and index the content? How does this work?
I have a master page containing a tree and 3 dropdown lists. I am populating a context menu on right click of each node, and when clicked on any item of the context menu, it navigates to required pages.
My problem is after navigating to the required page, the selected values from the drop down lists and the selected node from the tree are getting cleared.
I can set the selected values for the dropdown lists by making some properties in master page. But how do i maintain the selected node?
In my content page, i have got the valuepath of the right clicked node.
Or is there any other way than setting the properties in master page?
I have a GridView on ASP.NET web form which I have bound to a data source and set it to have 10 records per page.
I also have a hyper link column on the GridView, such that a user can navigate to another page (details page) from the list. On the details page, they have "Back" button to return to the GridView page
I am looking for sample code snippet on the Server Side on how to specify the page index to set the GridView after data binding.
how can i make next or previous button in asp.net? for example, in collection will display all product that i sell...and i want the URL appear like this "/collections/other-fashion?page=1", when user click next, the URL change to "/collections/other-fashion?page=2"..is it i have to make many form? i just want to use 1 form...im using vb languange
Is there any easy way to set properties of a Page (or UserControl for that matter) from *within itself*?As an example, I have several .aspx pages which inherit from exactly the same code-behind class, but I need to be able to pass different properties to the class to make them do the correct thing for the specific .aspx. The only way I've found to do this is to create the following - which works fine, but doesn't feel right....
<script runat="server"> Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init Me.MyProperty = True End Sub </script>
It would be a much nicer, simplier and easier solution to be able to be able to set MyProperty = True somewhere... is this possible?The option of hard-coding properties within the class for the "parent" page is not going to work for my situation.
I have a title in my master page, say, "I am master". In my content page, in the page_load event, I change it to:Me.Title = Me.Master.Page.Title & ", I am content"So I expect the title to be "I am master, I am content". However, it just shows ", I am content". This has been working so far.
In my web application I need to Search a gridview by a Text which entered in a textbox, and in a Button_Click().
I need to search the Text in a particular column only, so I use the gridviewrow property and searched which item template contains the Text. But, it works in the First page index of the GridView not in the Next and others, How can I Enable the Search Up-to the Last page index and the Last row of the GridView.
Right now I have a gridview with databind. My menu item consist of the 7 days of the week. Everything works fine except for one thing, the page index. Right now by default it loads the results for Monday. If I click on Pg 2 for Monday, and then I click on Tuesday, the page number stays at page 2 and the data remains the same. I have to click on Pg 1 or Pg 3 before the data would refresh and change the result to Tuesday's data.
I've tried adding databind() to the MenuClick event but if Monday has 3 pages, and they click on Tuesday which only has 2 pages, it would give me an error. Also the adding of the Databind() still doesn't fix the page index when I click on a different day.
How do I reset the page index when the user clicks on the day.
