Gridview with two dropdownlists causing error.
I have a dropdownlist2 in a gridview whose datasource and select control parameter is based on the selected value of dropdownlist1 in the same gridview. Everything works great for insert, but when I edit the row in the gridview and change the selected value in dropdownlist1, I get an error of "'dropdownlist2 ' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value" This kinda makes sense... -

gridview checkbox not udpating
I have a gridview with an update capabilities - a textbox column (roomName), a dropdownlist(or gID), a dropdownlist(ro omTypeID),a checkbox column (dialOut), a checkbox column (dialIn). When I try to add another checkbox column, the sql database isn't updated properly with a 0/1 or false/true but with null. I've tried everything I can think of. Can anyone help?
Data command stuff:

It appears that
doCalc() will allow me to iterate through the datagrid rows and change cells but not access the footer? I tried to change the text in a text box at the "ElseIf i.ItemType = ListItemType.Fo oter Then" point and it didn't work. The doCalc() doesn't explicitly call the datagrideventar gs cause I want to call it from multiple sources (textbox textchanged, dropdownlist selected indexes, etc.) Can I explictly...Leave a comment:

I can reference a textbox outside of the datagrid and change THAT at the time the calculation is done. But I can't get the text in a footer cell or a label text located in a footer cell to change. That help?Leave a comment:

Yep, anytime the dropdownlist outside the datagrid changes, or one of the textboxes within the datagrid changes, or the dropdownlist in one of the datagrid cells changes, I fire the doCalc and the cells in the fourth column of the datagrid change on the fly. But, I can't get the footer to show any changes....Leave a comment:

Okay balablaster, you've been great and I'm sorry to ask, but I'm confused. The doCalc is fired at will after the page has rendered when the client does something on the screen. So, the datagrid, column cells are changed, but the footer cells are not changing.
Sub doCalc()
Dim varTotal As Integer = 0
For Each i As DataGridItem In dgList.Items
If (i.ItemType = ListItemType.Al ternatingItem...Leave a comment:

Got the delegate datagrid dropdownlist to fire. Now, last piece is getting the footer to update. Anybody got any pointers?
Thanks so much.Leave a comment:

Never could get it right, so I'm coming at it a different way.
Created a datagrid, and want to change the text in a column and a footer cell based on changes in two dropdownlists. The first dropdownlist changes the text in the fourth column fine, but I can't get it to change the footer text. Each columm in the datagrid has a <footertemplate > The second dropdownlist is in the datagrid, but doesn't seem to fire the doCalc sub....Leave a comment:

Yeah, I do get it now. Thanks for the explanation. That really helps. But, why doesn't this work? And/or how would you get it to work to reference and/or set the value of the text box? Thanks so much.

Plater,
Thanks for the reply. Still a bit confused about the exact syntax.
Dim myUID As String
myUID = "txtUID" & i.ToString
Page.FindContro l(CType(myUID, TextBox))
above tells me string cannot be converted to textbox
Dim myUID As TextBox
myUID.ID = "txtUID" & i.ToString
above stops me before I can...Leave a comment:

Iterate through a reference of controls
If I have 3 text boxes with ids of txtBox1, txtBox2, txtBox3, how does one reference them for the text values?
Dim varStart as integer=1
Dim varEnd as integer=3
Dim myUID As TextBox
for i = varStart to varEnd
myUID.ID = ("txtUID" & i.ToString)
If (Trim(CType(myU ID, TextBox).Text) <> "") then
do something
End if

So sorry, does this help?
I know, I know, I've read the posts, but I can't get it to work. Scenario is:
Page 1 = registration page
Page 2 = cc company page (I can't touch)
Page 3 = return page for cc company
Page 4 = my second page of receipt
Pages 1, 3, 4, all use my master page, wherein I have:
Code:Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles

The message seems to imply the end event is causing a problem. Could it be that it's looking for a response.cookie object that isn't there because it's been abandoned through the button onClick event (or timed out because the client just left the machine there and walked away past the set time out)? Would something like this prevent the error?
If IsDBNull(Respon se.Cookies) = False Then
