Getting a button click without knowing the button

Question

I have 22 buttons, and i want all of them to run the same method, which will:
1.Get the name of the button that was hit.
2.Perform a task based on which button was hit.(probably a switch statement). Is there and easier/ faster way to set the click methods without setting all 22 buttons?

is there at least a way to find the button that was clicked?

Answer 1

write this in codebehind. This reads the data from the database but u can use the readXml method of the dataset and popluate.

Public Function PopulateTitle() As DataSet
Dim cn As New SqlConnection
Dim daPricing As SqlDataAdapter
Dim dsPricing As New DataSet
Dim TempList As New DropDownList
Dim myRow As DataRow
cn = New SqlClient.SqlConnection("ur connection string")
cn.Open()
daPricing = New SqlDataAdapter("SELECT TITLE, TITLE_ID FROM XYZ ORDER BY TITLE", cn)
daPricing.Fill(dsPricing)
PopulateTitle = dsPricing
dsPricing.Dispose()
daPricing.Dispose()
cn.Close()
End Function

write the following in .aspx
   <asp:TemplateColumn HeaderText="Title">
      <ItemTemplate>
       <asp:Label ID="lblTitle" Text='<%# DataBinder.Eval(Container.DataItem, "TITLE") %>' Runat="server" Width="176px" />
      </ItemTemplate>
      <EditItemTemplate>
       <asp:DropDownList id="ddlTitle" runat="server" DataSource="<%# PopulateTitle %>" DataTextField="TITLE" DataValueField="SERVICE_ID" OnPreRender="setTitle" Width="176px">
       </asp:DropDownList>
      </EditItemTemplate>
     </asp:TemplateColumn>

Method which is highlighted is as follows

Public Sub setTitle(ByVal sender As Object, ByVal e As System.EventArgs)
Dim ddlTitle As DropDownList
ddlTitle = sender
If (Not ddlTitle Is Nothing And strServiceTitle <> "") Then
ddlTitle.ClearSelection()
ddlTitle.Items.FindByText(strServiceTitle).Selected = True
End If
End Sub

strServiceTitle is:

Public Sub edit(ByVal sender As System.Object, ByVal e As DataGridCommandEventArgs)strServiceTitle = CType(e.Item.FindControl("lbltitle"), Label).Text
End Sub

Firstly you will have to use the asp:TemplateColumn Use the itemdatabound event of the datagrid In this evnet you will have to check for the ItemType if it is ListItemType.EditItem then you can populate the control of that particular cell. Hope this helps :) Anuj
