ASP.NEt editing gridview cells

27-Jan-08 21:50

Use template column and put a new grid inside that. Find this inner grid in main grid's data bound event. Bind the child grid with the required data. By default the child grid's style can be set to "none" and when the link is clicked, using JS change this visibility to "block" which will display your inner grid.

GridView1.Visible = true;
GridView1.PageIndex = e.NewPageIndex;

You are not setting the data source again. You need to set the data source again in the page index changed event, before you do DataBind().

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.Visible = true;
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataSource = YourDataTable;
    GridView1.DataBind();
}

Very clear... Laugh | :laugh:

When the paging is clicked, the page will postback, where your DataTable will be clear. So you have to generate the DataTable again and assign it to the GridView. Call the DataBind now.

Hi,

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
Gridview1.DataSource = tblData; //this should be your data table
GridView1.DataBind();
}

The logic written above will work if and only if you declare your data table as shared,
(i.e) shared tblData as DataTable

Designer Error in WorkFlow Project - VS 2005

Hi,

I am trying to create a custom workflow using Visual Studio 2005 for SharePoint Services 3.0.

I've installed the VS 2005 extensions for SharePoint and for WorkFlow Foundation. When I try to create a new project, I'm getting the error:

" The designer could not be shown for this file because none of the classes within it can be designed."

Initially it showed that the dll "microsoft.sharepoint.WorkflowActions" could not be found. So I copied this dll form Server where WSS 3.0 is installed and put in "C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\ISAPI" in my PC and added the reference. Still the designer error persists.

Could someone please assist me with this issue?

Regards,
Blumen

Wouldn't it do this by the file association from the suffix anyway? Another approch is to stream the bytes to the output stream and set the mime type.

Try using "server.Transfer"

I already tried file association and mime type was defined but webbrowser still tried to download the file rather then handingover to programme

please is there any programmitacaly approach with vb on asp.net page to capture the click event and redirect that event to programme like using shell command

will pray for you

You can't do this as it is completely decided by the browser. If it is video files, use silverlight to play streaming videos. For other file types, it should get downloaded for accessing it.

If you are using windows application, I think you can use WebClient class and download the file to a temporary location which user doesn't knows. Then use Process.Start() to launch the associated application.

i don't know this is proper solution or not but you can try this
if you want to open that file with proper player then just run that file
when user clicks the url user process class to run that file

Static method

N a v a n e e t h27-Jan-08 7:11

27-Jan-08 7:11

So, I have a class User, which encapsulates all user related data. The class has a static (factory) method,FromId(string id) which returns a user instance. My question is, if multiple users are requesting this method at same time, will this return correct value ? I am confused here.

public class User
{
     public static User FromId(string id)
     {
          //Code to create user instance and return
     }
}

Yes. Thread safety is only an issue if there are static variables whose values are updated within the method.

Read this article for more information[^] on the subject.

Thanks. I know this. But my method is static, not any variables. So will the thread safety issue comes here ? All my variables are instance variables.

I think it will return proper user if the instance that you are returning from the static function is created in that function only.
