Web Forms :: Set Enter Key Button For Gridview Footer Template?
Sep 7, 2010
[URL]
I have used the above grid view in my application ... Its working good, no problem.
Upon clicking the Addnewrowbutton, it uses to create a new row dynamically.
What i need is, new row should also be created dynamically, upon pressing enter key in the last textbox on a particular gird view row. User always can't go and click addnewrowbutton every time to create new row. Instead of it, user can press enter in the last textbox on a particular grid view row to create new row.

I have created a gridview dynamically from scratch and added it to my aspx page. This works fine, but i have a button in the footer of on of the columns, which when clicked on makes the gridview disappear and doesn't fire the onclick event that it should. This should obviously not be the case. My question is why does the event not fire and why does the gridview vanish? Bear in mind i have never created aa gridview in the code behind before, so excuse me if i am being dense
Code creating columns
Dim gvTownships As New GridView
'COLUMNS
Dim tmpCategory As New TemplateField
tmpCategory.ItemTemplate = New cGridViewTemplate(DataControlRowType.DataRow, "Category")
tmpCategory.HeaderTemplate = New cGridViewTemplate(DataControlRowType.Header, "Category")
tmpCategory.FooterTemplate = New cGridViewTemplate(DataControlRowType.Footer, "Calculation")
'INFORMATION
gvTownships.AutoGenerateColumns = False
gvTownships.ID = cmbChoice.SelectedItem.Text
gvTownships.ShowFooter = True
gvTownships.CssClass = "mGrid"
gvTownships.RowStyle.Wrap = False
gvTownships.HeaderStyle.CssClass = "mgrid"
gvTownships.HeaderStyle.Wrap = True
gvTownships.FooterStyle.CssClass = "mGridtf"
gvTownships.AlternatingRowStyle.CssClass = "alt"
gvTownships.GridLines = GridLines.Both
'add columns
gvTownships.Columns.Add(tmpCategory)
gvTownships.DataSource = dstSuburbTowhShip
gvTownships.DataBind()
Code to add button to footer
Sub InstantiateIn(ByVal container As System.Web.UI.Control) _
Implements ITemplate.InstantiateIn
Case DataControlRowType.Footer
If columnName = "Calculation" Then
Dim btnCalculate As New Button
btnCalculate.Text = "Calculate"
btnCalculate.CssClass = "button"
'add handler
AddHandler btnCalculate.Click, AddressOf btnCalculate_Clicked
container.Controls.Add(btnCalculate)
End If
Case Else
' Insert code to handle unexpected values.
End Select
End Sub
Private Sub btnCalculate_Clicked(ByVal sender As Object, ByVal e As EventArgs)
Try
Dim btnCalculate As Button = CType(sender, Button)
Dim gvRow As GridViewRow = CType(btnCalculate.NamingContainer, GridViewRow)
btnCalculate.CommandArgument = "Calculate"
Catch ex As Exception
End Try
End Sub
End Class

I have a textbox added in an item template so I can enter data. But when I press enter in a textbox it caused the page to postback and I lose the data entered. I can tab through fine but why does Enter cause a postback? Can I disable this?

I have 3 buttons that change the Information being displayed in my Gridview (Previous, Today, Forward). Now management wants to SUM the Date's information by column, I have figured out how to do this by changing the BoundField to a TemplateField and then add a FooterTemplate with a SQL DataSource. When I Press either the Previous or Forward button the data does not change in my Sum'd Footer column.

I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Below is my code
<asp:GridView runat="server" ID="gridManageClients" AutoGenerateColumns="False" OnRowCommand="gridRowCommand">
<Columns>
<asp:BoundField DataField="Clientid" ItemStyle-Width="75px" />
<asp:BoundField DataField="ClientName" ItemStyle-Width="300px" /> [code]...
