I have the following questions regarding pagination in a gridview.. First as a beginner i used default pagination for all my gridviews..
After checking out some articles on performance they all focus on custom pagination...
Is it a bad practice to use default pagination of a gridview? When to use custom pagination over default pagination in a gridview?
I am using ObjectDataSource controll to bind gridview and using custom paging. Everything working fine but the problem arises when last page contains only one record and i try to delete it-- gridview disappear.
Below is ObjectDataSource declaration..It is working fine..only problem is with deleting from last
page which is containing only single record.

I have created a website that has some gridview controls that call stored procedures in a SQL db and display the results of the procedures. Two of the gridview controls have sorting enabled, and one has pagination enabled.
The site loads for all users who have tried it so far.
However, one user gets a "webpage not found" (HTTP 400 Bad request) error whenever they click on the pagination links or sorting links on the gridview control. It seems like it's not a security issue because the website runs as a user with permission to the database.

I'm facing a wierd problem with GridView and ObjectDataSource. I bind GridView to my business objects via ObjectDataSource. Everything was working fine until I decided to add a new field in my buisness object and wanted to add a column to GridView to show it. Somehow that column is NOT shown in the GridView's list of available columns. I have tried refreshing schema, rebinding, etc. I'm using GridView inside a user control which is used as a web part. Does that make a difference ?
View 3 RepliesI have been asked to replace DATAGRID with GRIDVIEW on WEBFORM1.ASPX. For Pagination, I am having problem due to lack of knowledge to replace page 1,2,3,4,5,6,7 8, 0 with NEXT , PREV like I did it for DATAGRID. Have to use NEXT and PREV because the GRIDVIEW Pagesize = 20 while the rows from the TBLSALESTRANSACTION exceeded 350rows
View 6 RepliesI have a grid that receives products over a GetList methods via ObjectDataSource. The Product class contains also a Object Supplier. If I change in the drop down list of the grid the supplier for a product and I click update the ID of the suppliier is still the same. I have debugged the call of the update method and checked the parameter in the product object. I wrote the following code in the SelectedIndexChanged event and the text box shows the right id but not the update method.
DropDownList supplier = (DropDownList) sender;
txtTest.Text = supplier.SelectedValue;
Here is the code of my grid view:
[Code]....
My Object Data Source calls the following Update Method:

The next work around idea would be to call the update method manually in the Update Event of the grid view.
Can you post of an example of Gridview with EditItemTemplate using ObjectDataSource as data connectionand Update the the specific row. Ihave lots of sleepness night with this problem.
View 2 RepliesI've been working a gridview that uses an ObjectDataSource to perform either select, insert, delete or update. I was able to get everything to work correctly with the GridView except when it came to performing an update. My first issue that I came across was that it was tacking on two extra columns or fields that I didn't really expect. The function being called (SavePipelineUser) only expected 4 parameters and was getting 6 in total. This was occuring even though I had placed OldValuesParameterFormatString="original_{0}" or OldValuesParameterFormatString="{0}" within the GridView's attributes.
Ok, So I was able to resolve this issue by going into the OnUpdating event in the ObjectDataSource and doing the following below. This effectively removes the additional parameters from being added. However, I now have a new problem. There doesn't appear to be any values actually being passed into this method. So, while no errors appear, nothing gets updated. Can anyone explain to me why my values are not being carried forward? I've spent about a day and a half working on this issue and was able to get around this by just going with the GridView's RowUpdating event and grabbing values from grid to manually get it to update. While I'm very happy for anything to be working after so much time, I still feel like this is a bad hack for this to work. I have a hard time fathoming why this seemingly simple use of the GridView on my part has turned out to be very complicated. I'm extremely leary now of using the ObjectDataSource object for anything if it's going to be this much of an effort.

AllowSorting="True" DataSourceID="objCommon" AutoGenerateColumns="False" ShowFooter="True"

I'm using a GridView with an ObejctDataSource. The data is provided by a business object and not a DB. It returns a list of people and each person belongs to a group. Now I need to filter data. For example, I need to return list of people in specific groups. How can I specify a list of groups to be able to filter the data ? Could I use SQL like syntax ? I understand the filter expression works only when data is returned as a datatable. But in my business object I maintain data as hashtables and return as List<PeopleInfo>. Do I need to return list as datatable instead ?
View 2 RepliesI have a gridview with the ObjectDataSource and the Update does not work. When I click on Edit, I go to Edit mode but Update will not work at all. No errors. I do believe that it is in the RowUpdating method but cannot figure out how to call the method UpdateBook from the BookManager BAL.

Put in Breakpoints and it is getting to the RowUpdating but will not update.
I get the following error when trying to delete a row in a gridview. The error is strange, since I dont pass 2 parameters as far as I can see.This is the error and the code is below:

I have a gridview being data bound by an objectdatasource which points to a BLL/DAL. I have paging and sorting enabled within the gridview. I have the fields configured in the look/fell I want from a templatefield. This templatefield has the sort expression (date) I want things to be sorted by. All this works as it should and I have no issues with it.But, the issue is that when I click on the header to sort asc/desc by date, I have to click on it twice for it switch to descending order. E.g. I hit the webpage and it lists all the information in the gridview, sorted by date, ascending order. If I want to sort by descending order, I have to click the date header twice in order for the gridview to sort the information in descending order; the clicks cause a post-back and the whole screen is refreshed.
View 2 RepliesI am having some difficulty enabling sorting on a gridview that has data in it that has come from an objectdatasource.
The AllowSorting="True" function doesnt work for ObjectDataSource so I need to find a work around...I am guessing that I will need to do something in code in order to get this off the ground.
I have an ObjectDataSource giving me data similar to: OrderNumber OrderDate OrderValue OrderItems The first three are simple data types and the last has multiple occurrences of another class: OrderLineNumber OrderItem OrderQuantity The ObjectDataSource will only contain one row (which might make things simpler). So, there will be one OrderNumber, OrderDate and OrderValue; and then several occurrences of OrderItems (each containing OrderLineNumber, OrderItem and OrderQuantity).
I am displaying OrderNumber, OrderDate and OrderValue in the FormView - that work's fine, as expected. I have placed a GridView within the FormView and am failing miserably to get it to bind to OrderItems. I have tried the obvious things like specifying "odsWhatever.OrderItems" as the DataSourceID for the GridView, but to no avail.
i have been following the asp.net data access tutorials on this site. When i try to update, nothing happens. I believe the problem lies with my wrong coding on the BLL part. I'm using table adapters. Could anyone point out what iswrong with my code or tell my what the correct code is?

VS2010 Ultimate ASP.NET 4.0 Web Appliction project
I have a simple aspx page with a GridView Bound to an ObjectDataSource utilizing a class object that returns a DataView.
There are no errors generated, but the GridView does not display any rows. If I check the return value of the ObjectDataSource in the Selected event in the Immediate window (?CType(e.ReturnValue,DataView).Count), there are 51 rows. However, (?Me.GridView1.Rows.Count) shows 0 rows. The exact same page in VS2008, ASP.NET 3.5 works fine. how to get the GridView to display the rows? What has been done to the GridView in 4.0?

I am a new user of ASP.NET 2.0 (VB.NET)
I am facing a problem related to GridView Control
I have a table <UsersDetail> with following structure in MySQL
FIELDNAME | DATATYPE
---------------------------------------
userid | Numeric
Userlogin | Varchar(25)
Userpassword | Varchar(25)
Firstname | Varchar(50)
Lastname | Varchar(50)
---------------------------------------
I wrote a code to fetch data from this table :
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
<asp:GridView ID="myGridView" runat="server" AutoGenerateColumns="false" AllowPaging="True" PageSize="3" Width="520px">
<Columns>
<asp:TemplateField HeaderText="User ID">
<ItemTemplate>
<asp:Label ID="Label3" Text='<%#Eval("userid") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="User Login">
<ItemTemplate>
<asp:Label ID="Label4" Text='<%#Eval("Userlogin") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Pack Amount">
<ItemTemplate>
<asp:Label ID="Password" Text='<%#Eval("Userpassword") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="For">
<ItemTemplate>
<asp:Label ID="First name" Text='<%#Eval("Firstname") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Validity">
<ItemTemplate>
<asp:Label ID="Last name" Text='<%#Eval("Lastname") %> Months' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
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.
