I have sub classed a asp repeater similar to A Grouping Repeater All works fine apart from if I also have a <HeaderTemplate> </HeaderTemplate> The grouping template is rendered before the header template. I would really like to either be able to choose the order in which the templates are rendered or just have the <GroupTemplate> Rendered after the header.
I am using a repater whose item template is having a dropdownlist. Now i want to access that dropdownlist from a button click event. Here is the code iam using :
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 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 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.
