Forms Data Controls :: Gridview Paging Resets Form Controls?
Sep 28, 2010
I have a gridview which has 4 columns, each holding an ImageButton in a templateField column. When I click on one of these image buttons the clicked upon image is displayed in Image1 using GridView1_RowCommand and this works fine.
However, when I click on one of the page numbers on the gridview the Image1 control resets to its original state and loses its ImageUrl.
Below is the HTML source for the gridview.

What is the process for allowing paging in a gridview on a page where the user submits information in order to fill the gridview?
The gridview is being fill without a datasource but instead with a datatable.

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,
[Code]....
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.

I have a GridView with edit/delete column, label column and DropDownList column. I have a textbox outside the GridView and I want to choose only those rows from the GridView which have for the second column the same value as the value of the textbox while paging.
I wrote code, but I got 0 rows as a result, which is not true.

Background of what I have implmented so far:
I've used datagrid view to show a list on records on page, the list contains huge number of records so paging was required. Since the amount of data was huge it was not advisable to bind the grid with complete data. So, I used custom paging and tweaked the sql statements to get page wise data. Now whenever user clicks next or previous data for current page is fetched from the database and gridview is binded with that much data only.
Now I had to add a checkbox column to the grid so that user can select multiple items on multiple pages and perform an operation (for example send email to selected people in the list). I achieved this by making a template column with checkbox control and keeping a boolean column in the datatable which is binded to the gridview. I've also kept a collection selected checboxes so that the state is maintained on every postback.
I've also used ajax so that user cannot see postback happeneing. Everything works just perfect.Here comes the problem:
Now say I have 5 pages of data to be displayed. I select 3 people from first page and move to next page, this will cause fresh databinding and previous data will be lost.Now I go on and select 3 more people from page 2Finally press the send mail button What is expected here is that the mail should be sent to 6 people but details of only 3 people are available because grid is rebinded.
What is the best way to cach data of selected rows in this case. The number of columns is around 20 out of which I show only 10 columns on screen and others are kept hidden. The values of hidden columns are used while sending the emails.

We have a page the we have to write where users are shown 'pages' of data from our database they then select the row they want and we take them into another part of the application where they can work with the data.
When we use the built in paging (in the gridview) it is just too slow, as there is too much data.
We have written paging into our stored procedure that gets the data to work around this. The stored procedure works just fine and it is quite fast.
How can I get 'paging' buttons into my gridview when I am not using the built in gridview paging?I can keep it simple if I have to (next and previous only) but it would be better to have a 'first', 'previous', 'next', 'last' type buttons.
I cannot seem to figure out how to get these buttons into the gridview however.
some sample code (preferably vb) that would show this? (or something similar)
Built in paging is not an option.

As a part of requirement, I need to bind a table data to the Gridview, but the data content in the table is too large. I need not want to bring in all the data into the dataset, rather I need to bring only the rows that are needed to be displayed(Eg, if the page size is 10, i need only 10 records to be filled in dataset

I have a gridview control which contains aproximately 2,040 records of IP addresses. Right now I have setup my gridview control with the following options: AllowPaging="True" PageSize="255".
This has the effect of placing each IP range on its own page. So for instance 192.168.0.1-192.168.0.255 is on page 1, and 192.168.1.0-192.168.1-255 is on page 2 and so forth. The issue is that finding the IP range I want in the application is really a pain and I usually have to click page by page through the gridview to find the range I want to edit.
I'd like to have a custom paging and instead having pagination which says 1,2,3,4,5,6 etc had more meaningful labels like "192.168.0.x Range", "10.10.10.1 Range", "172.22.50.x range" and so forth. So that I can immediately jump to the page that I want. note that in most cases I need to browse the data not search for a specific element so creating a searchbox isn't neccessarily the answer. I just need more efficient paging.
I'm not really sure how to accomplish this. I've tried searching google for custom pagination + gridview etc and I'm not having much luck. Maybe I don't have the right combo of search terms.

I currently have a gridview on my page, which has PageSize="10" AllowPaging="true" set, so we're getting back records in groups of 10, and paging is showing as 1 2 3 4 etc... the client is asking if it's possible to also add an ALL at the end of the paging, so paging would look like:
1 2 3 4 ... ALL
clicking ALL would show everything, as if the grid was set to show all from the beginning, is this possible? anyone know how? I thought maybe the <PagerSettings LastPageText="ALL" /> would help get me started, at least show the ALL at the end, but that didn't work for me. also wasn't then sure how to setup the click event to clear the grid's settings.

We have an application that runs with IE. Iīm trying to set up a ASP site. The application has some kind of autofunction. If the textboxes is named correctly they will read the data from a SQL server table (eg names, addresses).
I have set up a panel and a button (button2"). When the button is used the panel becomes visible. However this does also resets the form to itīs initial state. Letīs say I have changed the name input and then press the button, itīs reset the form and inputs to itīs earlier value. I donīt want that to happen. Also the button "mail" isnīt visible until I press the button to show the panel, but the button "mail" is not included in the panel.
Why is this happen?

Im pretty confused on this and would appreciate any suggestions.Im trying to implement custom paging because my database has some 400,000ish records and i want to show 20 at a time in a gridview. I don't want to use a datasource in the html because this gridview gets populated using a dataset in the .cs (c#) because
the user first filters on params. I have two sp (on to get the total record count and one that filters). Both sp work.

Does anyone know how i can tell my gridview (and if i need to implement a datapager) the total number of records, to get the page numbers on the bottom correct and then pass the parameter @PageNum @PageSize@sortExpression?

I have a page that I am creating 5 separate GridViews on, depending on the button the user clicks, a different GridView will show up. On a few of the GridView's there is a need for paging, so in the CodeBehind I did the following
