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]

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.

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.
at System.Web.UI.WebControls.GridView.get_StateFormatter() at
System.Web.UI.WebControls.GridView.BuildCallbackArgument(Int32 pageIndex) at
System.Web.UI.WebControls.GridView.CreateNumericPager(TableRow row, PagedDataSource pagedDataSource, Boolean addFirstLastPageButtons) at
System.Web.UI.WebControls.GridView.InitializePager(GridViewRow row, Int32 columnSpan,

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]

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.

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.

I have a GridView in a page with paging enabled (sorting not enabled, not used). OnRowDataBound and OnPageIndexChanged events are assigned.
<asp:GridView ShowHeader="False" ID="GV1" runat="server" AutoGenerateColumns="False" OnRowDataBound="gridView_RowDataBound" DataSourceID="SqlDataSource1" GridLines="None" CellPadding="0" PageSize="25" AllowPaging="True" OnPageIndexChanging="GV1_PageIndexChanging">

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">

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>

I've got a gridview (ASP.net) inside of an update panel. I also have a "Save" button so that when I click "Save" it loops through all the rows of a grid view and passes the data to a stored procedure to update each row. This was too slow as sometimes I would be updating the database even though a change did not occur.
I decided to add a field in my gridview like so:
<asp:TemplateField>
<ItemTemplate>
<input type="hidden" id="hdnIsChanged" runat="server" />

how i can get the grid to select a row by clicking on any cell in the row?
The only way i can do this at the moment is by setting the AutoGenerateSelectButton property to True, but this adds a column to the grid with a crude "select" hyperlink and only selects the row if the word "Select" is cliked on.

Basically what needs to happen is when the user clicks edit onto the gridview and clicks on a certain textbox a javascript calendar popups up and the user picks a date.So far, I can set it statically and the calendar works for that one row, but not the other rows since the ID changes.My ASP Code (id of textbox has been set to txtStartDate):
<asp:TemplateField SortExpression="StartDate" HeaderText="Start Date">
<EditItemTemplate>
<asp:TextBox ID="txtStartDate" onClick="ddlchange()" Runat="server" Text='<%#Bind("StartDate")%>'>
[code]....
This works, for one textbox. It does not work for other since 'ct102' changes with every row.

Apparently, part of the problem is that while an ASP:GridView has an OnDataBound() event (which you can use in the code-behind), the corresponding HTML table that is produced does NOT, so you can attach that event to JavaScript. (Did I get that right?) So, that's why I'm having trouble with that bit of the issue. Back to the drawing board. I'm a desktop developer (WinForms with VB.NET) transitioning into ASP.NET development. My mind is really bending around the DOM and JavaScript and Session State and all of the stuff that goes along with web development. I'm not stupid, and I've done research (including hours of video watching and hundreds of pages of "Intro to ASP.NET" reading), but I keep hitting the wall with what seem to be fairly straightforward problems.
Basically, my current situation can be summed up as follows:
I have a page that runs a very long process initiated by the user. The long process can take up to a few minutes , so I want to indicate to the user that SOMETHING is happening.When the process has completed, I either have:
a. Results to show in a GridView
b. No results to show
If I have results to show, I want to display them. If I have no results to show, I want to show a label to the user that says "No results to show."

I have a jQuery 'toggle' function on a table that I am using in conjunction with an asp.net gridview. I have pagination on my gridview and when I click on the next page, it posts back and therefore closes the Toggle/Table - I need a way of keeping it open. I have had a similar issue in the past with the Accordion function but resolved it via this method
<asp:HiddenField ID="hidAccordionIndex" runat="server" Value="0" />
<script language="javascript" type="text/javascript">

I have aspx gridview with checkbox on evryrow, what is required is whenever we check any of the rows, a query should be launched to change the specific agent -each row consist of agentID, Pass, Status- to Paid Status. using javascriptWhat I need to know is how to loop to get the Checked row and get the ID of the row checked so that I can get THe ID of the Agent in thos row so that I can update its status.using javascriptI found something similar on stackflow:t GridView selected row DataKey in JavascriptBut it is not my case, what is needed is at the check of a checkbox a javascript function should launch through which I could update the selected row in grid view after having the index of this row and this all to avoid refreshing the page.

I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.
I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

How do I print the page title and the header of a GridView on each print page?
I want to add page title and GridView heading on each page.
I used page break to break the GridView into multiple pages, but only the first page comes with title and all other are without header and title page.
For a dynamic GridView, my code uses AutoGenerateColumns="true".

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.
