When i try to connect to sql express database in the project i am getting this error. can anyone help me?
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Thanks annd regards

Hi to all,
I'm trying to invoke a method in ASP from JScript page (OnClick or anything similar to it) on the same related .aspx page with no success.
can someone please explain me how something like that can be done?
|
|
|
|

I am not sure about the method but you can fire the event from java script. by using do_postback method.

1 child1 0
2 child2 0
3 gchild1 1
4 gchild2 1
5 gchild3 2
6 gchild4 2
7 ggchild1 3
.... and so on.
now i want to populate the ASP.NET tree view with the table entries by querying the eids and parentids.
i am using ASP.NET 1.1. so i am using microsoft web controls.
TreeView:
Root
---child1
------gchild1
----------ggchild1
------gchild2
---child2
------gchild3
------gchild4

I'll try to make this as simple as possible, it's just to give you some idea...
Table "TreeItems":
item_id, item_parent, item_caption, item_url
Main Code:
[Run Query] SELECT * FROM TreeItems WHERE IsNull(item_parent) OR IsEmpty(item_parent)
[Loop ResultSet]
[Create Parent Node]
RecursiveScan(thisnode, item_id);
[Add Parent Node to Treeview]
[End Loop ResultSet]
RecursiveScan (Parent_Node, ParentId)
{
[Run Query] SELECT * FROM TreeItems WHERE item_parent = @ParentId
[Loop ResultSet]
[Create Child Node]
RecursiveAddNodes(thisnode, item_id);
[Add Child Node to Parent]
[End Loop ResultSet]
}
of course you will have to adapt to your custom table settings and to the treeview control you are using, I've never used microsoft web controls before.

In ASP.NET 1.1. I am having a template checkbox column in a dynamically created datagrid. Inorder to maintain the viewstate, i initialize the datagrid in Page_Init itself and modify the datagrid through Ajax Function. The Ajax function will modify the enabled property of checkboxes. After AJAX method is invoked, in next Postback, i'm able to get the checked property of checkbox from Viewstate but not able to get the enabled property from viewstate. But if i don't perform Ajax Modification, in postback i'm able to get both enabled and checked property.
Kindly provide any idea regarding why enabled property is not in viewstate after using AJAX Function

Hi,
I know of three ways to inject some strings into an aspx:
- <%= which is the old ASP way
- <%# which is used in databinding expressions
- <%$ which can be used to evaluate certain expressions such as AppSettings:MySettings or ConnectionStrings:MyConnectionString (assuming that MySettings and MyConnectionString are defined in web.config in the appropriate sections).
So, are there any more? I'm trying to inject the value of a const variable into the DataNavigateUrlFormatString property of an HyperLinkColumn, if I use <%# it complains that the template doesn't support DataBinding, if I use <%= it just gets rendered as is (i.e. the name of the constant, not the value of it), and if I use <%$ it complains that the constant is not on the form "Expression:Value" (and I REALLY don't want to write a custom Expression builder for injecting a single constant into an aspx page...).
What am I missing? Any help would be very much appreciated
Regards,
Daniel

Problem with Context User when I authenticate users in the same thread of a process
Hi, I hope you can help me with this problem, (in spite of my english!
I use CustomIdentity to authenticate the users in my webapp and read some information (Language, ID....) of the context user. It works fine if users use different browser instances for access the webapp, but if they use different threads of the same process, context user of these threads are mixed.
Some example
1) Alice opens iexplorer and connect to the webapp. She authenticates herself with her user 'UserAlice' and goes into. At this moment exist one process (iexplorer.exe) running
2) Alice open another iexplorer and connect to the webapp. She authenticates herself with another user that she managed 'UserAlice2' and goes into. At this moment exists two process (iexplorer.exe of step 1 and this one). These users can works fine at the same time
3) Alice uses 'open new window' command from the browser that she opened at step 2. (At this moment exist two process, not three) If she connect to the webapp and authenticates herself with another user that she managed 'UserAlice3' , the context user of the step 2 will be replaced for this user, and, in spite of the tree users connected (UserAlice,UserAlice2 and UserAlice3) at the tree different window browser, we have only two users (UserAlice on the first window and UserAlice2 at the others)
I need that people can manage diferent users on the same machine, but I can't control that they use new browsers spite of 'new window' commands. Besides, I need that they connect to the webapp from a link in a mail, and this action causes always that iexplorer starts a new thread, not a new process....
I use this code to authenticate users:
CustomIdentity userIdentity = new CustomIdentity(user.Name, 1, true, false, student.Surname + " " + student.Name, student.Email, user.Language, "");<br />
ArrayList roles = User.GetRoles();<br />
CustomPrincipal principal = new CustomPrincipal(userIdentity, roles);<br />
Context.User = principal;
Thanks in advance, any help would be appreciated

Hi, I am Ravindra.Currently learning ASP.net.
In my project I came across to develop a Registration form, It contains two textboxes:
one for :To enter Email addr,
other to: confirm the Email addr.
I want to make the First textBox property to set in such a way that it does not allow "the user to copy the entered email address (ie in textBox1)to another textbox(textBox2)".
If anybody know please help................

First I have to say that don't really see any reason for this. The double entering of values is a service to the user to help verify that the data is correctly entered. If the users don't want this help, they can circumvent it on their own risk. It might feel awkward for the user to enter the same data twice, but it's all for their benefit. If you try to force them to use this feature, it will feel even more awkward. I think that it's more effective to try to educate the users of the reason for this feature, instead of forcing it upon them.
It might be possible to prohibit copying and pasting, but it's not that easy to make it work in all browsers, as it's not really a browser function but rather a system function. There is no simple setting that allows you to control copying and pasting in a field.
