I am using windows Vista. I never deployed any site from that system.
I found in program and feature , i had forgotten to on iis and other asp.net services.It worked for me , might be this will also help you.
Here is the steps to on services:

- Control Panel
- Program and Features
- Turn Windows Features On or Off
Here you will find different - different services. checked those services whatever services you need to run your site.
That worked for me, hope it will also work for you

Publish Failed

Hi friend,

If you don't have any error on your build and still you are getting publish failed error and you have no idea what is happening. Just Check the output window of your visual studio. Output window you can find in view menu.

Check Box in GridView

GridView is very power fool control in .NET. Whatever the control we want to add we can add very easily.

Here is the simple Example of ad a check box in GridView:-



Just Double Click on image and see only bold text. I am using here ItemTemplate By the Item Style tag we can set style of a control which i am using inside the ItemTemplate . After this i am placing check box control. We can place any control whatever we want . After this i am taking a hidden control which i will use at the time of fetch the value corresponding to selected check box.

Here is the code for accessing the value of check box control:-


foreach (GridViewRow row in GridView1.Rows)
{
if (((CheckBox)(row.Cells[0].FindControl("RowLevelCheckBox"))).Checked)
{

string id = ((HtmlInputHidden)(row.Cells[0].FindControl("RowLevelIdHidden"))).Value.Trim() ;
sendValue(siteiId,adIdStr, "activated");
}
}

By this code snippet i am sending selected check box's id to sendvalue function.

I hope this blog is useful for you.
