Does any one know how set the FormView PageIndex to a DataItem with a specified DataKey?
Like:
DataKey dataKeyVal = myGridView.SelectedDataKey.value
myFormView.PageIndex = FormView.DataItems.GetByDataKeyVal(DataKey dataKeyVal).Index
The FormView is bound to the same ObjectDataSource as the GridView and the FormView uses the autoPaging so I can't just use a separate DataSource for the FormView with just one parameter being the ID.
There must be a way to set the FormView PageIndex by a Datakey value.
I have a Gridview with ID "GVSeasonsOfResort" which has selectable rows.
One of the fields in that gridview is RSLinkID which is an ID field of the table from which ths SQLDataSource driving the gridview gets its data.
I have a textbox outside the gridview with ID TxtBxRSLinkID and when I select a row of the Gridview, I want to assign the value of the RSLinkID field of the selected row to the TxtBxRSLinkID.

I have done this before "n" number of times but I am not able to get it working this time. The trouble is that when the call for the Select Method of the formview goes to the relevant function - "GetCustomerByCusnum" I have a null value in its parameter "cusnum".
I know that I can write a selecting event and using CommandArgument, parse the value of the selected row and pass it into the Select method as a value but I dont want that solution. I know it works without the "Selecting" method but I cant recall how.

View 3 RepliesIn my gridview, I have 6 columns. The first 5 columns are filled with data retrieved from database.In the 6th column I want to display a value from textbox from same form. The value should be displayed on the row next to last row of rest of the columns. So my last column (i.e.) 6th column will just have all the rows filled with the same value of the text box.
First 5 columns of grid will be filled by selecting the college name from dropdown.The last colum (Date) must be filled with the date that is given in the textbox.It can be even after button click event(date of attendence).
It can be done after button click event also..

Retrieving datakey value in gridview?
Lets say for example that I have a book object that looks like this:
[Code]....
And a Page_Load method that bounds a GridView called "gvBooks" from a generic list of books:
[Code]....
Now as you can see, I want to have the BookId value that is part of the Dictionary as a DataKey of the gvBooks GridView.
That piece of code of curse returns an Exception:
"DataBinding: 'GridViewTest.Book' does not contain a property with the name 'BookId'."
My question is: Is it possible to have the BookId value as a DataKey of the GridView?
I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.

I have wired an event to handle delete command for my GridView. But I cannot determine which the record's unique key, in my case stored in DOCIDNO field. All I get is a row index, such as 0, 1, 2 which obviously cannot be used to accurately delete a record from database.

How to get the DataKey value in RowDataBound event for GridView
View 3 RepliesI have a gridview with a DropDownList (contained in a TemplateField). I have set the OnSelectedIndexChanged event to a function called "ddlAgent_SelectedIndexChanged" This allows me to aquire when a user has changed the value for the dropdownlist. What I need to do is persist this newly selected value to the database for the gridview record. The problem I'm having is how to I get the datakeyNames value for that row? See code below!
TemplateField source
<asp:TemplateField HeaderText="Agent">
<ItemTemplate>
<asp:DropDownList ID="ddlAgent" runat="server" AutoPostBack="False" OnSelectedIndexChanged="ddlAgent_SelectedIndexChanged">
</asp:DropDownList>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
ddlAgent_SelectedIndexChanged
Protected Sub ddlAgent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim gvItems As DropDownList = CType(sender, DropDownList)
' Write the selected Agent ID to the Inquiry record.
'Dim ID As Integer = gvMaint.DataKeyNames(e.SelectedIndex).Value ' THIS FAILS BECAUSE
e.SelectedIndex is not part of System.EventArgs
End Sub

I am binding SQL data to a GridView. The GridView's DataKeyNames property is set to the SQL column called "utID"
I know that within the SQL results, some of the utID values are NULL. After databinding to the GridView, I need to enumerate through the GridViewRows an read the DataKey values. However, when I try this I get the following error:
No default member found for type 'DBNull'. I am using the code below.
