Forms Data Controls :: How To Find Total Row Counts With Gridview Control And Default Paging Enabled
Feb 3, 2010
how to get the total row counts in a Gridview control with default paging enabled? My gridview control is bind to an ObjectDataSource control.
The problem I am having right now is that when I loop through the gridview control, it only contains the total row for the current page being displayed on the screen and not
the total row in the entire grid. I am using the the for each loop.
I have a gridview and having trouble with display when the webpage is saved as pdf. I can see just the first page of gridview. If I dont do pagination and save the file, the gridview just breaks up and half is displayed on firstpage and half on next page. is there a way that if the gidview cannot fit on one page, I can break it and display rest of it on nextpage?
im working on drag drop rows from one grid view to another,its working fine until page size is 1,when records exceeds from 5(as my page size in grid view is 5) 2 pages are display in grid view,,now when i drag row from other grid view to this gridview ,row s dropped in this gridview but beside this it also drop on pages (1,2)display on this (destination)grid view..
I am working on Add To Cart Functionality, and I have added a GridView control with paging enabled. In the GridView, I show the quantity in a text box and handle the OnTextChanged event for that textbox. Now the problem, is how can I keep the changed quantity text in session or view state, and in which row, so that I can update my GridView and bind that data again to the GridView?
Here I took GridView with id gvMaster.

I want to show changed quantity value in grid with paging enabled.
I currently have a GridView control on my aspx page with paging enabled and I need to loop through the entire row collection/count to process the selected records. With my current code, it will only loop through the current page of GridView row.
foreach (GridViewRow data in grid.Rows) { //here is my code }
I tried to keep all the data in the gridview when paging, but when I try to save it, which appears in my database only when it is active pages .. ex: in the first and second page I have data in gridview .. when I save, the stored in the database only the first or second page of course .. so I like to keep all my data in gridview when paging..
i have tried using : foreach (GridViewRow row in GridCustomColumn.Rows) but it's not working..
string sql1; foreach (GridViewRow row in GridCustomColumn.Rows) {
i have one grid which have 5 columns 1 for subject,2,3,4 for marks which have textbox to insert obtained marks,and last column have one lable to display total of (2+3+4),now i want total value on textbox event,when user enter any value to any column of textbox i need to display total of all three columns in total column.
I am trying to add a label in my gridview that counts the number of records that are being displayed as well as the total number of records found via the datasource. and i want this label to be displayed in the pager template of the gridview i.e. at the bottom.
I have the following code:
[Code]....
which i run in the rowdatabound method of the gridview. but when i run it it comes up with an error saying "null reference exception handles by code".i think the error lies in not being able to count the total number of rows in the sqldatasource in the int variable intTotalRecords. How do i go about counting the number of rows in the datasource that i am trying to pass in?
I am trying to show as part of the Gridview table the amount of records found as a total in one of the Gridviews rows. I have some code which does add a row to the Gridview but it does not seem to be counting the number of rows it just shows 0 all the tim. Does anyone know why this might be? you can see the count "visitCount" and the dt.Rows.Add but it doesn't increment
I have data grid with page size 15. I need to find total number of record(s) in a grid. How to do it?There is two ways to do:
1) Here I have used LINQ. So calling stored procedure again and we can done using .Count () property. But here I don't want make call to data base again.2) Creating our own logic like here I have done like:
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 have a nested gridview like the code quoted below. How to retrieve the counter of each child gridview elements and display it as a field of the parent gridview ?
Dim Con As New MySqlConnection Dim Cmd As New MySqlCommand Dim Adp As New MySqlDataAdapter Dim DTable As DataTable Con.ConnectionString = ConfigurationManager.ConnectionStrings("dbConString").ConnectionString Cmd.CommandType = CommandType.StoredProcedure Cmd.CommandText = "sp_FetchAllUsers" Cmd.Connection = Con Adp = New MySqlDataAdapter Adp.SelectCommand = Cmd DTable = New DataTable Adp.Fill(DTable) GridView1.DataSource = DTable GridView1.DataBind()
Basically Gridview controls is used to display data in tabular format. but due to requirement I changed its layout to columner in following manner
Now come to the problem, i set the AllowPaging="True" and page size to 3 records/page but when click on paging links it displays the following error :
The GridView 'myGridView' fired event PageIndexChanging which wasn't handled.
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.Web.HttpException: The GridView 'myGridView' fired event PageIndexChanging which wasn't handled.
I want to create user control for gridview paging, so it may be reusable for every grid in my application, my user control should be like below, how its possible
eg: previous 1,2,3,4,5,6,7,8,9,10 More If i clicks more link next 10 pages of records should be visible, how its process?
Without paging function, i can loop through the gridview by using
var sum = 0; var gridViewCtlId = '<%=timesheetView.ClientID%>'; var grid = document.getElementById(gridViewCtlId); var gridLength = grid.rows.length;
so with gridLength i can loop through the gridview to sum all rows. However, when I use paging event of gridview, i use the page size to loop through all rows, but it occurs errors because the last page may not have enough rows.
String conn = System.Configuration.ConfigurationManager.ConnectionStrings["conString"].ConnectionString; SqlConnection con = new SqlConnection(); // for connection SqlDataAdapter adp = new SqlDataAdapter(); // for fetch the records acc. to condition DataTable dt = new DataTable(); // fill the fetched records DataTable tb; // will store the session
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 a gridview control i added checkbox contrl dynamically but i am not getiing the reference of checkbox in button clilck event here is my code Gridvew
