I am doing a project using .net 2.0 C#. I used the SqlDataSource control to populate the database and then attach it to the gridview. The gridview works well if I run the code first time, meaning the gridview will display that SqlDataSource. But how can I achieve to display that SqlDataSource only upon user clicking a button called btnRefresh.
thanks in advance. Much appreciated.

In btnRefresh_click method only you open the connection and bind the gridview
|

There are many ways to do that:
+ You don't assign the id of the SqlDataSource control to the DataSourceId property of the GridView control until the button is clicked.
+ In the button click event handler, you can call the Select method of the datasource control and assign the result to the GridView control.
+ You can manage to populate the datasource instead of using the SqlDataSource control in the button click event handler.
+ You can keep doing the way that you are familar but only make the GridView control visible until the button is clicked.

Actually I have a textbox for user to key data and then when the user click btnSubmit, that data will be stored in the database.

I kind of like this method. However I encounter error, if I click btnRefresh, the database its not updated.
thanks in advance. Much appreciated.

how to resolve this?
The process cannot access the file "C:\Inetpub\wwwroot\MetSysClient\Upload\Blue hills.jpg" because it is being used by another process.
Private Sub cmdDelImg_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdDelImg.Click<br />
<br />
Try<br />
<br />
Dim sDelFile As String<br />
sDelFile = msLoc & sImageName & ".jpg"<br />
'File.Delete(sDelFile)<br />
<br />
'Using the FileInfo class<br />
Dim fInfo As FileInfo<br />
fInfo = New FileInfo(sDelFile)<br />
fInfo.Delete()<br />
<br />
Catch ex As Exception<br />
txtErrorMessage.Visible = True<br />
txtErrorMessage.Text = ex.Message<br />
<br />
End Try<br />
<br />
End Sub

Some application is using the file, perhaps yours? Have you opened the file earlier, like displaying it in a picture box? If you don't dispose the image object properly, the file is still open.

b { font-weight: normal; }

the page is a thumbnail gallery.. maybe asp is using the image i really don't know.. but is there a way to delete it even if the image is open?
|
|
|
|
|
if some program is using that file then there is no way u can delete that.

If you opened the image with a stream, or some object and you didn't close it, yes, you won't be able to delete it. However if you are only referencing it as a source for an image object in asp.net, that isn't really holding it. Either there is a stream holding it or some other program you use in your PC. If unsure, try to delete manually, if you get the same message, reset iis, and try to delete manually again, if it's deleted then you have something in your program that's locking it, otherwise another program is locking it.
If all else fails, may be asp.net doesn't have proper rights to delete it.

Is it possible to call a web service method from another web service? I am a beginner and know how to create a web service and to call a web service method from asp.net. But my client is asking me to develop a web service to call other web service. Please explain in details or if possible please provide me with some samples.
Thanks in advance,
Bala

Of course you can
A web service is a project, so you can simply reference your web service from your OTHER web service just like you did when you referenced the web service from the asp.net project.

Hi, good day.
I have a question about the checkbox in datagrid.
The problem is i have a datagrid in my page and i have 4 checkbox per row in the datagrid. I use the radio button to select the record and i can check the checkbox for certain specify action.
For an example, i select the record to be print in different type of report format. The checkbos is use to select which report format need to be printed out.
Did anyone can help me to solve this problem? Thanks..

what exactly is the problem which you are getting in that? As you can put all the checkboxes in the itemtemplate column of the datagrid and same with the radio button.

Hi.. my problem is in the datagrid i got 4 columns are chechbox. Each of the column with checkbox represent different type of report printing format( that is each column's checkbox will be redirect to the specify report page when the user checked on it). When user checked the checkbox, how i get to know the status on which report need to be printed out by the user.
Thanks.. 
Best Regards,
Pei Sun

when you want to know that which checkbox has been checked? Do you want to go to the server when user has checked any checkbox or after user checked the checkbox and clicks on some button?
Best Regards,

yup.. user will click the "OK" button after checked the checbox on the selected record. User will be redirect to the page which the user have checked. If the user check more then 1 checkbox, user will be redirect to the report type page one follow another.

And what will happen if the user has checked for the multiple rows of the datagrid (ofcourse different options in the checkbox)?

User only can select one row at a time because i use radio button to select the row.

Then you can use foreach loop to iterate through all the rows and then can find the checkbox and their value and do the operation as required.

Is it possible to keep the checkbox value and pass to another page? Because i need the checkbox value to perform another operation. Thanks..

No directly it is not possible but what you can do is you can store it in some session variable or if it is not big then can also be send through querystring.

how to write the code using query string? The value of the checkbox is which page the user will be redirect to. If use session, how the code looks like? Thanks.
