hi,
The problem im facing is that when i open the solution of an asp.net project the .NET returns this error. "Visual Studio .NET cannot open or create the application. The likeliest problem is that the required components are not installed on the local web server. Im using Visual Studio .NET 2003 and Framework is 1.1.
thanx.

You need IIS installed (V 5.0 or higher if I recall). You also need to register ASP.NET with IIS using aspnet_regiis.

Hi,
try to repair your IIS
cd %windir%\Microsoft.NET\Framework\v1.1.4322
aspnet_regiis -i
if it is not working...
The VSWebCache folder is created automatically by Visual Studio when you open/create a web project and can be found in <root>\Documents and Settings\<user>\VSWebCache\<machinename>. Simply delete this folder and VS will recreate it when you attempt (now successfully) to open the web project.

Please don't repost. None here is going to take-up your work and do for you. we can give you some idea's to sort out your problem. what about this?[^]. Did you give a try?
Give a proper subject line like Accessing XML Nodes Using DOM. This will definitely turn other's attention.

It will work if you give the node path correctly. Your code works fine in my system.

No. It is not possible to do.... but you may try ActiveX control or Flash for that purpose but it will work only IE and your site should be in trusted website list... i suggest that it is better if you don't do this...

The hyperlink may have an OnClientClick function, I know a button does. In there you can write a function call to a method that returns true or false, and the return value will decide if the OnClick postback is called. If the hyperlink does not offer that, why not use an anchor tag instead of a server control, then you can have the link call a javascript method which redirects only if certain conditions are met.

i should not use the button control, it will not show me the data associated with the page (which i have binded with the page name (query string sort of things.)), the page , where i will redirect the user to some respective page.how can i use the anchor tag , to implement it?

You may try by calling a function on the onclick event of the hyperlink.
Use following logic.
//Process
if (true)
window.location.href ="url"
else
//do nothing

Good Day,
I need some help identiying the proper command terminology to create the type of page I would like.
What I am trying to do is take a format that will have data populated into it, but on the previous page I cache a session variable where I have "number of servers" and that number will determine how many times that template will appear on the next page with incremented servers names (i.e. server1, server2 etc...).
A link or even just the terminology so i can google it will work.
thanks

I have a Repeater control that hosts simple User List rows of system users. Each row has an Edit icon, which the user clicks to open a User Details edit page. I have been told to remove the separate details page, and create a detail edit section that expands or collapses on demand, without leaving the base User List page. How do I go about this?
My first idea is to include an edit control on the item template of the Repeater, and simply use styling to hide the edit control until the edit icon is clicked. Then I set the display to a visible, and the edit control handles all the edit functionality itself. Is this the correct approach, how could I improve on this, and what pitfalls await me?

Repeater Control doesn't support this. You can use DataList Control which has a selected Item Template where you can have the template to show the Details of the Selected Item. This will expand when you select the item and collapse the selected item when you select the other item by changing the selectedItem Index in the code-behind. And it has Edit-Item Template to edit the Item.

Thanks, I've been looking at the DataList, and will look at it some more now. How does this expanding and collapsing work if, say, the row is the last row in a 'window' (a fixed size div)?
I wasn't planning on supporting this through the Repeater, but through Javascript. All the Repeater would do is emit the hidden DHTML for the the rows and detail, it would be agnostic as to what was happening.
|
|
|
|

yes, Using repeater you can have the Details in the <-div> hidden and show them when you select the Item. this(expand and collapse) can be acheived through javascript. The page which we are using here in (CP) is something similar to the interface which you are talking. But I don't think you can provide the edit option using repeater control. you have to take the user to a different page for editing.

I will also be providing the edit function through Javascript. I already do this in other pages, with in-grid editing, using the blur event of the various controls.
|
|
|
|
|
I think it's the right method. But after editing how will you update it back to the database ? I am confused how will you get an event for the button to update it back to database ?
