    - Migration from CF1.0 to CF2.0 I have migrated my compact framework application from CF1.0 to CF2.0 using the wizard in VS 2005. I have also upgraded the project using "Upgrade Project" option in the Project menu. After migration when I look into the project, I understand that the project in the applications are migrated to ".NET Compact Framework 1.0 forms application for Pocket PC 2003". Is there any way to upgrade the project to .NET Compact Framework 2.0 forms application? I observed all the project properties are same for the both the projects(.NET Compact Framework 1.0 forms application and .NET Compact Framework 2.0 forms application) in VS 2005. Is there any difference between these two projects?(.NET Compact Framework 1.0 forms application for Pocket PC 2003 and .NET Compact Framework 2.0 forms application) Please let me know Thanks Sri Tag: Number Format Tag: 65983

    - Toolbar buttons and transparency Hi, I use VS2005, CF1 I create a toolbar and a button on it. I use a 16x16 .gif picture with 256 colors and I mark one color from its palette as a transparency key (in Photoshop). But at runtime this color appears as the white color although the toolbar background is gray. So what is the right solution to have transparency when creating toolbar buttons?

    - Smart Device CAB Project: AddReg key is always added to inf file. When VS2005 generates inf file it always add AddReg key to [DefaultInstall] section. But my application does not have any entries in registry. This leads to warnings in CabWiz.log: Warning: Section [RegKeys] has no data Warning: Section [DefaultInstall] key "AddReg" - there are no section entries to process How can I force Smart Device CAB Project generate proper inf file?

    - DocumentList CF 2.0 Hi all, DocumentList control has its own predefined context menu. May I know how can customize this context menu as I would like to add additional items into it? Currently, the context menu is not exposed through the property. Secondly, how can I invoke methods like Rename/Move, Beam File functions etc similar to the context menu of documentlist control from Menu control. I would like to provide the flexibility to access same funtionalities from Menu control to the user as in the context menu of a documentlist. Are there any API that I can invoke to call these functions (Rename/Move, Beam File etc)? Thanks in advance. Tag: Number Format Tag: 65953

Any other suggestions for uploading an .ics file to a webserver is also apreciated, but I would prefer using webdav as iCal (OS X) does.

    - Form.Close won't close the form. Hello, I'm getting a strange behavior. When I open a form using the Form.Show() method, Form.Close() doesn't seem to do anything. However, If I display the form using the Form.ShowDialog() method, then Form.Close() cloeses the form just fine; Has anyone else noticed this strange behaviour? Is there any way to bypass it without resorting to displaying all forms modally? Thanks you in advance. Tag: Number Format Tag: 65939

    - PDA needs to be reset to be able to start our app. again Hello, we're writing some app. for Pocket PCs using CF 1.0 and openNETCF 1.4 for RS232 communication. On one device we get an exception at closing the RS232 port which says something like this: "A thread (hex) has ended with 0". It seems to me that some thread has been ended what could be normal but: we close our app then because we wanted to finish anyway and the app. isn't listed under running programs anymore, what would be okay either. Problem: the user now can start any app. on his Pocket PC but not ours! Ours won't run unless you're rebooting the Pocket PC (soft reset)! What is wrong here? Why do we get this? It's a device with WM 5.0 but on another modell with WM 5.0 all is fine... and on others with WM 2003 it's fine as well! Greetings Markus Tag: Number Format Tag: 65895

    - PerformClick Ok I have created a custom control that inherits from button. I am using CF 2.0. I know that OpenNetCF has a button that implements the PerformClick event, but I want to create my own. I have created my own, and the PerformClick method works just fine after the form is loaded. However, if I do the PerformClick in the load event it does something quarky. It flashes the new form I am trying to load and then goes back to the original. I am trying to load another form from the click event. The new form loads fine, and then it goes back to the original form. It's like it sends it to the back or something. If I set the second form's TopMost property the form shows on top as expected. Does anyone have a clue what is happening. It's driving me crazy.

    - ListView MouseDown Event Hi, I am trying to add the following functionality: - I have a ListView with a few columns that is in Detail view with single row select enabled. I have added the ability for the user to tap on one of the rows in the ListView to open up a new Form containing the details of the item that was tapped. I also need to have a ContextMenu to popup when the user performs a tap & hold on one of the rows. I have implemented the SelectedIndexChanged handler to detect when the user selects a row and open up a Form with the appropriate information. I have also ascribed a ContextMenu to the ListView. The ContextMenu appears fine if I tap & hold in the whitespace area of the ListView, however when I perform a tap & hold on one of the rows, the SelectedIndexChanged routine fires before the tap & hold support. I have tried various methods to get around this, including changing the Activation method for row selection/activation, etc. I then tried to author my own custom ListView control that captured the MouseDown event, however this event never seems to fire no matter where I tap the stylus. Can anyone please help me out with this issue and possibly point me in the direction of a code example or something similar. Any help with this issue would be greatly appreciated.

    - CF 2 + Sql Mobile : parameters slows queries... Bug ? Hi, I have a request which returns rows from a table with where clauses to filter results. One clause is a int comparison, and the other is a LIKE comparison. If I build the request with concatenation ("WHERE column = " + myval + " AND column2 LIKE '" + myval + "'"), it works well and return results in about 300 ms. If I code "properly" using SqlCeParameters, using the same values than before, the request takes up to 120 seconds ! I start to think it is a bug in Sql Mobile with LIKE clauses.

There is no formatting in native DataGrid. But you may consider the
alternative datagrid, like this one:
