Hi,
When manually binding an SqlDataSource, sorting and paging does not work on the GridView. Is there some kind of settings or code to make the sorting and paging work?
SqlDataSource1.SelectCommand() = sSQL
GridView1.DataSource = SqlDataSource1
GridView1.DataBind()
Note that when the SqlDataSource1 and the GridView is bind at design, the sort and paging work fine.
Thank you.

SPWeb sitet = sitecollectiont.OpenWeb();
sitet.AllowUnsafeUpdates = true;
SPListCollection lists = sitet.Lists;
foreach (SPList list in lists)
{
if (list.Title == "Outstandings") //this D. library
{
SPListItemCollection items = list.Items;
foreach (SPListItem item in items)

SPFile file = item.File;
string docName = file.Name;
if (docName.Equals("Balance_343,35725.doc"))

how can i specify certain file formats to be browsed by file upload control?
for example i just like my file upload control to browse JPG and GIF files
thank you

I tried this but there no way that you can show a specific type of files howerver after browsing you can check the extension and prompt the appropriate message.

I am using a Gridview which is getting it's data from a Stored procedure. The values passing to the stored procedure are coming from a QueryString.
When I run the GridView configuration the correct data is returned when I test the connection but when I run it, the gridview page just comes back blank and displays nothing.
Anyone any ideas?

It sounds as though you are missing a call to the DataBind() method of the gridview after settings its DataSource.
|
|
|
|
|
Thanks for the reply Brent but:
How and where can I set this?
macca
|
|
|
|
|
Hmm you must be using the visual interface to to get your data rather than coding your own data access layer. In that case I won't be able to help much ( I prefer to code my own DAL) other than to say it sounds as though your gridview is not bound to the data source correctly.

Brent, Got this sorted. I coded instead.
Thanks,

when a network is said to be intranet and when it said to be internet and when it said to be extranet? And anybody knows about the technical issues to make the network intranet,please share with me
Thank you

Typing that into Google would have been faster!
But because you made me curious: http://www.hcidata.info/inet.htm

The internet is just the entire net, without any limitations or specific purpose. An intranet is used to share information in a local network. An extranet is basically an intranet that you can access from outside the local network. Usually the only difference is which people you give a login to, i.e. an intranet can physically be an extranet because you can reach it from anywhere, but it's only used by people inside the company.

I have a question regarding Asynchronous Requests.
Is there some way the requests can be made to operate at the same time?
i have one button on the page. everytime user clicks the button a call to database is made Asynchronously and the results are shown in the grid on completion. For every database result there is a new row in the grid. The problem is, every asynchronous call executes after the previous one is completed showing a behaviour of queues. However i need pure asynchronous tasks that is the results of less time consuming should appear first even if it was started at later. for more clarity here is code for both aspx and aspx.cs. before executing this code please make sure the connection string is ok for your machine. on execution click the button immidiately more than one times and see the start and end times.
Looking forward to your reply. Thanks in advance.

Ishfaq Hussain

 Hi All
the Problem I am facing is that I am using RadioButtonList which is created Dynamically.
All I have to do is to trap the events of this RadioButtonList using JavaScript. and create 2 other controls on change selection of this RadioButtonList.
to add further to this is that I do not know the ClientID for items in RadioButtonList at the point of compilation.

No probs you need to register the javascript from server side so one thing pass the clientid of the radiobutton list from server i.g
<br />
RadioButton objects = new RadioButton();<br />
objects.ID = "Somthing";<br />
objects.Text = "Click me";<br />
this.Page.Form.Controls.Add(objects);<br />
<br />
objects.Attributes.Add("OnClick", "javascript:alert('"+objects.ClientID+"');");<br />
<br />
Thanks and Regards

i wanted to ask the example (a real life example) that pertains to the passport authentication.
According to my understanding it should be MSN Messenger
Is it right?

Passport authentication is simply a single sign on system that was developed by Microsoft. Basically this means that you should be able to sign into site B using exactly the same login mechanism as signing into site A because they both implement Passport authentication.
Passports are issued, maintained and validated by a central authority so sites don't need to maintain this issue themselves. All they need to do is call the relevant web service to authenticate a user and then provide access based on this process.

Hi Saurabh,
Once i also faced same problem but i wasn't using user control.
I made these changes in web.config file and it works.
Just add these tags in ur web.config file below </system.web> tag.
<location path="Forgetpassword.aspx">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
I am not sure wether it'll work or not but u can try it out.
