Iam finding the button control which is inside the Footer Template of Data list control.
i tried the below code but it is not working suggest me where iam doing wrong or how i find the control avaiable in footer template of Data list.
Here is my code
[Code]....
iam using the above code on button click
i have the code to test:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =8", Con)
Now, I need something like this:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" + LblInfoEditar.text, Con)
The problem:
The LblInfoEditar is outside the datalist so it works fine. (note: in this label I put a value like the 8)
But I have this label to test because I need to access a label inside datalist:
<asp:Label Visible="false" runat="server" ID="LblNumEntrevista" Text='<%# Container.DataItem("EntrevistadoCodigo") %>'></asp:Label>
The problem is: in this line I've to put something to access this LblNumEntrevista HOW?
I try:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" +
ListaPendentes.LblInfoEditar.text, Con)
But of course I don't work because I can't do this...

View 11 RepliesI want to raise an checkbox check-changed event but its not firing :( . It Dosent raise even an command event.
My Requirement :
My Requirement is that i have a Datalist with header checkbox in headertemplate and a child checkbox in itemtemplate and a gridview control. Checking and unchecking will update the gridview control.
I've been searching in all the forums, and websites for the last 4 hours without finding a solution for a problem that in the beginning I tought it was an easy one!!!This is my problem, I have a gridview with the following colums: select (link), Room Type (for hotels), and TotalThe total field Is a template field it has in the custom binding property a function: find_total(Eval("Room")) this function makes some calculation and returns the calculated Total value, and shows in the gridview without problems,The thing I cant do is: when the user clicks on the select link I want to get the text of the template field and put in a label control.
I tried, almost all the events of the datagrid, to reference the content of my template field but sometimes I receive a null value (seems that Im looking for the value before the find_total function has been executed) or I get an error "the index is out of range".I dont know how to approach this, I tought It has to be much easier, but Im very confused right now, if anybody knows how to do this
