GridView Paging Not Displaying Data After Switching Page
Nov 15, 2010
I'm having a bit of trouble with Paging within a GridView grid I have set up. I have added the paging but whenever I click on the next page or the last page buttons, the page refreshes and displays blank (i.e. no gridview but my regular search parameters are displayed.
I was trying to search for a solution throughout the web and came across someone that looked to have the same issue. He moved all of his queries into the Page Load method, and the paging seemed to work. I cannot do this because I have 2 different buttons: Search and My Order, both of which perform different queries based on if a date has been selected or what the search is on (Order Number, License Number, Description, Status, etc).
My paging method looks as follows:
From what I can tell this is an issue with no longer having the data set when making the paging call. Is there anythign that I can do?
I don't like gridview style. Therefore, I used table in repeater to display the search results. However, I couldn't do paging. Is there any solution for paging or other recomendation for displaying data instead of griewview(too boxy). I also tried DataList,but I couldn't work it out the way I like.
The code below is actually a webpart(Sharepoint 2007) that uses a gridview to display data from an sql server database, however, when a page number is clicked, the whole page refreshes. Is there any way I can modify the code to avoid page refresh when a page number is clicked?
I do long and slow query to get data to my GridView and I got lot of data, but when I'm changing page it loads as slow as at the start, it loads full data again and again, how to load data once and use paging without data loading?
Also the gridview 1 and 2 the datasource is an SqlDataSource.
but that didnt work . also tried some things in pageindexchanged and pageindexchanging but still no efect :(. and also tried with enableviewstate = false / true on both gridviews with diferent combinations, but still no luck.
the code works only when i have allowpaging = false, or when im on the first page of the gridview (for the first time) is that the number of coments is pasted into the label.
I have a two webpages,in my first webpage i have gridview with 8 pages(paging) and four coloumns.In fourth coloumn i have a link button to redirect tosecond webpage ,now i am in gridview 4 th page(paging) then i clicked the link button and move to second second webpage.
second webpage contain one button that will redirect to first webpage.if i come from second webpage to first webpage the gridview paging get reset.but i want to be on gridview 4th page(paging).
As I understand the "gridview" control has a select link that can be enabled, I am fairly new to web development but what I was hoping to do was to click on the select link and then have the record that I have selected display on a seperate webpage. Is this relatively easy to do? Can anyone point me in the right direction?
Editing a web site project with master page in VS2010Ultimate with SP1 and Win7Ultimate 64 bit. Former everything was working fine - all toolbox windows were available when editing master page or aspx page. Now with the master page all toolbox relevant tab were enabled and show - when switching to a aspx page only the HTML tab is shown and enabled. When checking all "Show all" all expected tabs are disabled.
Even the <asp:> namespace is a unrecognized namespace in the aspx file.
When compiling or debugging/running everything is ok.
How can I solve this problem? I'm using Win7 Ultimate 64 Bit, VS2010 Ultimate and IExplorer 9 and the latest updates from Microsoft.
I have a parent gridview5 with child gridview 6, today i deployed it to our dev server and on that server we have alot more records, so for the nested gridviews i need to enable paging on the parent gridview5. Doing so works fine, until i make a selection within the child gridview6, once any selection is made, and i try to page the page throws an error, i have the following bound to the parent gridview5.
I have a gridview control on a .aspx page (content form).
Paging is enabled on gridview control. It displays the page numbers at the bottom of the .aspx page. When I click on a page number say 3, I get error saying the "Exception Details: System.Web.HttpException: The GridView 'GridViewReconresults' fired event PageIndexChanging which wasn't handled."
Do I need to write special code to handle the paging? Because there is a grid in another page and it has bound columns and I didn't write any code for paging and it works perfectly fine.
Here is the code in the .aspx page that I have problem.
I'm trying to extend the GridView control to enable sorting and paging for any situation.
When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?
To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.
Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.
My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.
The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.
I hoping someone could answer a question for me. I am relatively new to developing web applications with .NET and I have question I can't seem to find a straight answer to. When allowing paging of a GridView control, how does retrieve the data per-page? Is all the data stored into an object, and then displayed x amount of rows at a time? Or, when moving from page to page, is it executing each time but restraining the result to the specified amount of rows?
I had gridview which get data from database according to two event .The first from method ,the second when selected ddl.it worked well ,I made paging and when I go through paging pages I must click two click on number of page to go to this page also all pages get same data for firt page
I have one filed that is encrypted using Rajindal algorithm and stored in MSSQL db.When I retrieve that column in gridview it's displayed in encrypted. I have the code that decrypts it but the problem is:How can I all loop throw this column values in the gridview and decrypt them all and display it in the gridview decrypted.See my code below:
GridView: Applying style to certain columns. I add GridView1_RowDataBound() and have the following line:At that time, my GridView did not need to use Paging. Now after I add Paging to my GridView (AllowPaging="true" and I have AutoGenerateColumns="false"), there is an exception for my
