It means your Request.UrlReferrer is null. Since it's a popup, IE don't get the referrer. I am not sure why this works with firefox and not with IE. HTTP referrer is unreliable and many firewalls can strip that out. Alternatively check you are getting referrer using JS. Or use window.opener.location which gives opener window's location (referrer).

Hello,
I know that Focus is a client-side event but is there a way to call a server-side event in my code-behind file in reponse to focus change in a DropDownList? Something like,
1. Handle the focus in the javascript in the .aspx file
2. call a server-side method inside that javascript event handler?
Is that possible at all? If yes a code sample would help, becasue whatever I tried did not seem to work.
THanks for reading!

You can force a postback by examining the javascript that does it in general. Or you can make an AJAX call.

Hello,
I need to capture the user response to a confirm dialog. if the user clicks cancel, the postback is cancelled and I want to do something else even if its a cancel. I just use the clientscript.registerstartupscript to show a confirm dialog. What should I be doing to accomplish what i wish to?
|
|
|
|
|
if you are using a button...
OnClientClick="return confirm('Sure??');"
This will prevent the postback if user selects cancel
and will submit the form if the user selects ok

Try this:

Won't this only work if the code behind is VB ?

I guess, im not sure if IIF is supported in c#, but there must be something similar, isnt there?
I just hope this guy gets the idea
If he is using c#, he will have to find something similar
But im not sure what language he is using
How can you tell he is using c#?
Alexei Rodriguez

(boolean expression) ? if true : if false is in C#. I don't know what he's using, I'd hope the syntax I am showing worked for both, I do try to use language agnostic constructs where I can.

Hi
I have 2 tables in database as follows:
table1:
id name state id
1 aaa 1,2
2 bbb 1,3
table2:
id state
1 ak
2 ny
3 jk
so the problem is that I want to display all the data of "table1" in a gridview and in place of "state id" I want to display "statename", for example in place of "1,2" I want to display "ak,ny".
How to do this?
Please help me .
Thanks

Are you asking for help with building an SQL statement?
If so, it might look like this:
Select t1.*, t2.State as StateAcro from table1 as t1 inner join table2 as t2 on (t1.id=t2.id)
Otherwise, could you elaborate a bit more?
|
|
|
|
|
Hi
Thanks for replying.
ids in table1 are seperated with commas so t1.id=t2.id will not work.
I need asp.net code to display table1 values as I explained in my previous post.
Thanks

Seems to me like you need to design your db better in future ( a joining table would have made this doable in the SQL ).
You can read your array of state names and Ids, then write a data binding statement that passes the id string to the code behind, where you use the split method and a string builder to build a string that contains the state abbreviations.

Hi Christian
Thanks for reply
Actually I am displaying names of states in a checkbox list and after submitting the form, storing selected checkbox stateids in database with stateids seperated by comma as in table1.
If you have any working example or else any suggestion, please send it.
Thanks

What I said. A joining table joins data where there's an arbitrary number of joins
id name state id
1 aaa 1,2
2 bbb 1,3
table2:
id state
1 ak
2 ny
3 jk
table3:
nameId, stateId
1, 1
1, 2
2, 1
2, 3
then table 1 loses the stateID column.

I believe you just add it to your bin folder and then refer to it from there.

Hi,
please i need a button to work on more than one validation group.

OK - I don't know if you can specify more than one group, if not, you have to dig into the javascript that the framwork generates and write your own code to call the different groups.

Hello,
I have a db that stores phone numbers in the following format: (###) ###-####. I would like to reformat the phone number to the this format (for mobile apps to pick up the number for dialing): ###-###-####. I have used the following line of code to attempt this reformatting but am still getting the phone number displayed in its original format.
<itemtemplate>
<asp:label runat="server" id="lblContact" text="">]]>'/>
Can anyone help me with this? Thanks in advance to all those that reply.

you can write it in your sql statement I think:
SELECT field,field2, FORMAT (Telephone,' (###)-##-#######' ) AS NewPhone FROM table
