I have a repeater control that contains a HeaderTemplate and an ItemTemplate.
Each item contains a checkbox with an ID of chkReconciled, and the header
contains a single checkbox with an ID of chkAll. I simply want to have
chkAll be checked if every item in the repeater has its checkbox checked. In
the code behind page, I can access the checked property of chkReconciled by
doing the following:
Dim CurrentCheckBox As CheckBox
CurrentCheckBox = rptDeposits.Items(I).FindControl("chkReconciled")
Then I can check if CurrentCheckBox.checked is true. That works fine.
However, I haven't been able to set the checked property for chkAll. Since
it isn't part of the items, I have been trying the following:
Dim CheckAll As CheckBox
CheckAll = rptDeposits.FindControl("chkAll")
CheckAll.Checked = True
However, when I try to set the checked property, I get an exception saying,
"Object reference not set to an instance of an object." I've experimented
with a dozen different ways of setting the checked property of CheckAll, to
no avail. Can anyone set me on the right path?! I'm pasting the ASPX code
for the repeater below.
Thanks!
Keith
