GridView - How To Add Paging To Query

Feb 1, 2011

I have a simple query:
Dim info As New SailMembersDataContext
Dim query = From p In info.Individuals
GridView1.DataSource = query
GridView1.DataBind()

How I can add paging to this query for example 10 on a page I have tried to use the built in paging on the GridView but this just produces the error:
The GridView 'GridView1' fired event PageIndexChanging which wasn't handled.
When trying to change to another page.

ASP .NET Gridview Paging With Javascript

Jun 13, 2011

I'm experiencing a problem when clicking on the page number within my ASP .NET gridview. When I click another page number, I am redirected to another unrelated page within my project.This wasn't a problem until I added jQuery to my masterpage, so I'm guessing there is some sort of conflict in the javascript code. When the aforementioned redirect happens, the page PageIndexChanging event isn't fired and there isn't a postback as far as I can tell. [code]

GridView - How To Get Paging Working

Mar 18, 2010

I'm really struggling to make the leap in understanding to get paging working for my gridview. I am creating a web part in vb.net so have programmatically created all the controls. For development I have an aspx page to view my work. I have created a table with code and then inserted my code created gridview. When i enable paging i get the following error.

Paging With Standard .net 2.0 Gridview

Apr 3, 2009

I am using a standart .net 2.0 Gridview which uses an XMLDatasource to populate the Grid. The Data property of the XMLDatasource is set dynamically which allows the gridview to change based on input.All this works fine however I am having problems with paging.I have set the AllowPaging Property to "true" and set the PageSize Property to "10". The GridView populates fine the first time around showing the first 10 records and the number of pages as hyperlinks at the bottom, BUT when i try to click on any of the page numbers to view them a message box pops up saying "Object reference not set to an instance of an object"..[code]

Re-retrieve Data When Paging Using Asp:GridView?

Sep 22, 2011

I have a .aspx search screen that displays the results of the search in an asp:GridView component. There can be up to approx 1000 records returned by the search. I want to implememt paging on the grid so that only 15 records are displayed at any one time and the user can page through the results.

I am retrieving the records by passing search parameters to a WCF service which returns a List of particular entity objects. I create a Datatable and insert one DataRow per entity object from the List. I then bind the grid view to the Datatable.

This is how my grid is defined in the .aspx page:

<asp:GridView ID="gridCat" runat="server" AutoGenerateColumns="False" DataKeyNames="CatalogueID"
HeaderStyle-CssClass="fieldHeading" RowStyle-CssClass="fieldContent"

[Code]....

Is there a better way to do this (or am I doing it wrong)? If not, which of the 3 options do you think is the best? I'm leaning towards option 2 as I don't think option 1 is performant and I don't want to be sending loads of unnecessary data back to the browser as per option 3.

Asp.net - Allow Paging On Gridview With Custom Databinding In Place?

Mar 17, 2012

I am a bit lost in concept how to implement what i want to do. I have a gridview, a checkboxlist. I bind the gridview on the page_load. Everytime user choose a checkboxlist, the gridview rebind as well. I have something like this now. This is not the actual code. Thanks so much.

[Code]....

So what do i put here in order to allow paging ? basically, I have 2 datatables in the above example. In the actual code, I have about 5 datatables with 4 checkboxlists. I can't use Datasource control. I need to do it in codebehind as all code already exists.

Radio Button Inside Gridview With Paging - ASP.NET?

Jul 12, 2009

Here is the asp code for the design, I have a gridview that lists all Leave dates selected w/ 2 radio buttons . The user may choose if it is for whole day or halfday which are represented by a radio button. I want to get the value of each row if the user wants half day or whole day for me to calculate the leave days.

-I can already get the value but on the first 5 rows only since my gridview is paged with paging size of 5. how can i get the value for the other items if I have more than 5?

<asp:GridView ID="gvDates" runat="server" AllowPaging="True"
AutoGenerateColumns="false" OnPageIndexChanging="gvDates_PageIndexChanging"
onrowdatabound="gvDates_RowDataBound" OnRowDeleting="gvDates_RowDeleting"
PageSize="5">

Paging Not Working In Asp.net Gridview Inside AJAX Updatepanel

Aug 27, 2009

I have an asp.net gridview that is originally bound to a sqldatasource control, but when the user presses an external button, it instead gets the contents of a datatable rather than a SQLdatasource control. I therefore had to write code in the PageIndexChanging event of the gridview to allow for paging. My code is as follows:

Protected Sub gvEvents_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvEvents.PageIndexChanging

gvEvents.PageIndex = e.NewPageIndex

gvEvents.DataBind()

This worked beautifully until I added an AJAX update panel so the whole page wouldn't postback every time it paged, and paging stopped working. I debugged it and discovered that it is actually calling the PageIndexChanging event, but nothing is happening. I searched the web and found a few people with the same problem, but their solutions did not work for me. There was one on this site whose problem was solved by the following:

In PageIndexchanging event, where you bind data to grid, make sure, data is again fetched from the DB

I don't know what that means; my data was being bound as demonstrated above. I have "enable paging" set to true and EnableSortingAndPagingCallbacks set to false.

I am including my markup for the updatepanel below.

<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ibtnSearch" />
</Triggers>

Query Database With Each Object In Arraylist And Databind To Gridview?

Apr 21, 2011

I have a function that returns a list of account numbers as an Arraylist. I am trying to use each account as a command parameter in another sub routine to get more data about each account number. This only returns the data for the last account number in the arraylist. I need to use each account number, call the database, get the additional information and store ALL of the data into a Gridview (databind). Example: If I had 3 account numbers in my arraylist return 3 rows of data to the gridview. I am struggling with how to get ALL of the information for each value (account number) in the Arraylist. Can someone point me in the right direction?? I think this can be done but I am not certain if my approach is correct or not. Perhaps I need to create datatables that contain the additional information for each value passed via the arraylist.

Private Function ReturnMultAccts(ByVal strAcct) As ArrayList
Dim acctsDetail As New ArrayList
Dim dsn As String = Configurati

Perform Paging In Datagridview?

i'm using a datagridview to display the records which are filled in my dataset. however i need to perform paging to display only selected numer of records (e.g: display only 10 records per page) and by using the buttons (like: FirstPage, NextPage, PreviousPage, Last Page) allow users to nevigate through the records. and possibily display the total number of records in my dataset (e.g: |< last <Next 10/100 previous> first >| ) this might sound very simple but i'm new in .net and so far whatever source code i found in google is moslty written in C# which i don't know.
