Forms Data Controls :: Set FormView PageIndex By DataKey Of Row?

Mar 17, 2010

Does any one know how set the FormView PageIndex to a DataItem with a specified DataKey?


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.

Unable To Get The Datakey Value Of A Selected Row In GridView For Use In FormView

Sep 15, 2010

I have a gridview like this :


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.

Data Controls :: Assign Value To Label Inside TemplateField Of GridView From TextBox?

Jan 5, 2013

In 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..

Lets say for example that I have a book object that looks like this:


And a Page_Load method that bounds a GridView called "gvBooks" from a generic list of books:


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'."

Forms Data Controls :: TemplateField In Gridview Not Passing DataKey Value?

Feb 4, 2010

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.

Forms Data Controls :: Get Datakey From Templatefield (dropdownlist) In Gridview

May 21, 2010

I 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">
<asp:DropDownList ID="ddlAgent" runat="server" AutoPostBack="False" OnSelectedIndexChanged="ddlAgent_SelectedIndexChanged">
<ItemStyle HorizontalAlign="Center"></ItemStyle>

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

Forms Data Controls :: GridView.DataKey Error: No Default Member Found For Type 'DBNull'?

Sep 16, 2010

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.

What object types are stored within DataKeys (I thought it was just integers or strings)

How to handle a NULL datakey value to prevent this error occurring?

I don't want to use Try Catch because it's too much of a 'hack'
