• Re: Dataset + ObjectDatasource + GridView + ASP.NET 2

  I did it about 20 times, sometimes it works for somethings, but mostly doesn't work. What I don't understand is why the primary key should be editable?

• TreeView + Checkbox postback

  How can I make the page postback after a checkbox is clicked on a treeview? I only get the events fired for the checkbox, after a user clicks to submit the page. The event TreeNodeDataBound doesn't seem to expose the checkbox, so I can attach a Javascript function "onclick".

• Extending Native Framework types?

  namespace System { public partial class String { public void DoSomething() { // here goes the code } } the code above works with String test = new String(); test.DoSomething(); but not with "mystring ".DoSomething(); Even though the VS2005 autocomplete works fine. What am I doing wrong?

• Re: Dataset + ObjectDatasource + GridView + ASP.NET 2

  OK, I set the primary key (banner_type_id), to read_only = true . But it doesn't make sense to enable editing of the primary key. Anyway, now I get a different error: Value cannot be null. Parameter name: Original_name Why do I get this error? Below is my object DataSource definition and GridView <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" DeleteMethod="Delete" InsertMethod="Insert" OldValuesParameterFormatString="original_{0}" SelectMethod="GetData" TypeName="gremioTableAdapters

• Re: ASP.NET 2 Beta 1

  Yes, ASP.NET 1.1 is also running on this server. ASP.NET 1.1 application still run fine. I have changed under IIS settings for the ASP.NET tab to use the correct version for the different applications. I still haven't resinstalled IIS .. that might be a last resort ... will I loose all my configurations on the server if I do this? With SQL Server Express Beta 1 I had major problems also on my laptop .. and now Beta 2 failed to install on my desktop machine .... so far, I have not been able to test

  I have ASP.NET 2 beta 1 running under Win2000 fine, until the day I was forced to uninstall Active Directory from this server. Now all ASP.NET 2 pages give me the following error ...
