Hi Developers
I have a datagrid contains Tasks in a Queue. Now I need to move tasks up and down with two Up and Down (in each row of Grid).
Note: Grid should Refresh after clicking on up/ down arrow and records need to be updated in database also.
Please let me know if you know further explanation for that.
Thanks in advance
Lets work it Out.........!

You need to have a sort order column, probably an int, that gets updated when the user clicks on one of the arrows. The column is updated and the gridview is refreshed and all is right with the world.
only two letters away from being an asset

This would suggest that a higher level config file (such as machine.config) is locking the attributes. This is normally done like this:
<configuration>
<location application="App1" allowOverride = "false">
<system.web>
</system.web>
</location>
</configuration>
Unfortunately, you cannot remove this at the level you are at. It is a feature to prevent you from overriding server settings that could compromise the server.

RPL - sorry to say, but if you're on a commercial web server then you probably aren't going to be able to do this via the upload file option because, as I stated earlier, the machine.config file has locked down parts of the settings.
Can you use FTP to transfer the file up instead?
Alternatively, you need to get your web host to relax the rules for your application.

This is usually due to some infinite recursion. Some piece of code is being called repeatedly from itself, or from something it calls.
|
|
|
|
|
thnx for help
so there is any proprites or method which clear my system stack.
Deepak

A stack, any stack, works on the prinicple of last on first off. To clear a stack you must remove the items in the reverse order in which they were placed.
In the case of the call stack of an application it means you have to continually return from methods without calling any new ones. Each time you return from a method the stack has less items on it. Each time you call a method the stack has more items on it.
Going back to your error. It looks like it is caused by infinite recursion. You must find where the recursion is getting out of control and fix it.

How can user change the size of column and row of gridview...
|
|
|
|
|
I have put following tags in web.config.
Aim is to grant access to users in "Administrators" role.But it is allowing all users wether Administrator or not.
<authentication mode="Windows" />
<authorization>
<allow roles="ServerName\Administrators" />
<deny users ="?"/>
</authorization>
Please help.
Thanks
|
|
|
|
|
You need to deny all users after allowing the Admin users to access, replace the ? with the * in the deny entry.
|
|
|
|
|
Thanks for reply.
i did the same but in this case it is not allowing anyone.
any idea?
