Forms Data Controls :: Server Side Paging In GridView By Coding?
Mar 4, 2010
I am trying to implement server side paging with gridview using coding by DAL and BOL concept.But the Problem is with the Gridview page index.As the No of rows retrived are equal to page size and hence I am not able to genearate pager information .I cannot use object data source as i have 2 generate this on some event by passing some arguments like button clickPlease let me know how can i resolve it.Can i use datapager,Or do i need 2 create custom hyperlinks or any alternative to display gridview page index.
Error is:- The data source does not support server-side data paging.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.NotSupportedException: The data source does not support server-side data paging.
Source Error: Line 34: con.Open(); Line 35: GridView1.DataSource = cmd.ExecuteReader(); Line 36: GridView1.DataBind(); Line 37: con.Close(); Line 38: }
Is there a way to use the GridView paging and having the links not use JavaScript. So that when you click on the page number 5 (for example) that link is a hyperlink.
i have taken a button in itemtemplate in gridview hte grid view have a column name votes i want when i click th button the value of votes increases by one of that particular row please provide the code in c# asp.net
The problem is that the DataPager appears to be using the Count property of the ListView to determine the total number of records, which in this case is 20. Somehow, it needs to know that there are 1,500, not 20 total records. The DataPager has a property TotalRowCount, but this is read-only.I have never seen a DataPager example with Server Side paging, but assumed that it could do Server Side Paging, otherwise what good is the QueryStringField attribute?
I am aware that you can do a custom paging solution using methodology like the 4GuysFromRolla did here http://www.4guysfromrolla.com/articles/031506-1.aspx, but I'd first like to know if a solution with the DataPager is possible before creating a custom solution.
UPDATE,The more I look at this, the more that I'm coming to the conclusion that this is not possible and that, unfortunately, the datapager is a control meant for small web sites only. What I want to do should really be quite simple if the control were built correctly. I want to be able to say
I've been looking for some hack to accomplish the same thing, but it appears that the datapager's TotalRowCount is computed from the actual number of items in the datasource that it's bound to. It seems very odd to me that Microsoft would create a ListViewPagedDataSource() class and a DataPager at the same time and not have them work correctly together, but this appears to have been what has happened.
UPDATE 2 (AHA MOMENT?It seems that it has been possible to do server side paging since .Net 2.0 by using an ObjectDataSource and customizing the SelectCountMethod(). I believe it should be possible to customize ObjectDataSource to suit my needs. Hmmm. I'm going away for the weekend, so it'll be a couple of days for me to see if this works. Stay tuned, true believers.
I have a results set of 3 columns and aproximately 40 records. Instead of a Gridview with paging enabled or a GridView to where you need to scroll down the page to view all the data, I'd like to have two tables side by side.Is there and easy way to acomplish this?
Regarding ASP.NET's GridView server control: Can I bind to a datasource in the code-behind, load the entire resultset, and then implement client-side paging without postbacks? If this isn't possible with GridView, I'm willing to implement a custom solution. EDIT: My GridView instance sits inside of a nyroModal (jQuery) pop-up div, which is why I need a non-postback solution.
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 Getting A Problem In DataGrid's ItemDataBound Event. I Am Calling A JavaScript Function In DataGrid's ItemDataBound Which Retrun The CellIndex And RowIndex Number On Which UserClick After That I Am Re-Binding The DataGrid With jQuery Function After That ItemDataBound Event Not Working. I Want To Call The Same Function Again. Is Their Any Method To Call A Server-Side Function On ItemDataBound Event Except Client-Side Function..
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 want to use a gridview with sorting and paging to display data from an SQL server, the query uses 3 joins and the full text search containstable. The from part of the query uses all 3 tables in the join.What is the best way to do this? I can think of a stored procedure, SQL directly in the SQLDataSource and creating a view in the database.I want good performance and would like to leverage the automatic sorting and paging features of the gridview as much as possible.
Edit:About size, I suspect very few records, total about 1000 and a query would typical result in no more than 100 records and most times much less.
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
