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'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, [Code] .....

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'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.
I am stuck at this part where I am unable to allow paging in the datagrid. I have tried this.

I want to add paging functionality to the datagridview in my windows form. I did a search in google and got some codes too but I am not able to implement in my code as the way I am binding data to gridview is different than the one shown by other codes (that i got from google). I have implemented update and delete also. So I dont want to alter my code but I need to add extra code to implement paging which i don't know.
