rangasamy007:1.how to get selected Thumbnail
viewer control item or item index.
The ThumbnailViewer class has a MouseClick event which you can subcribe to by:
- Open your form to design view in Visual Studio
- Right click on the Thumbnail control
- Select Properties in the context menu
- Go to the Events for the Thumbnail control
- Double click on the MouseClick event to have Visual Studio automatically create the event for you
The ThumbClickEventArgs argument has a lot of useful properties. One of them is the index of the currently selected Thumbnail.
rangasamy007: 2. i want to implement delete option in Thumbnail viewer control for
selected item on right click event. whenever the user right click on
selected Thumbnail viewer control and should show delete option.
You can easily add a context menu to the Thumbnail control and have it only display when the mouse is over a Thumbnail (as opposed to also being visible when it's over the space between Thumbnails). Here's some example VB.Net Code:
Private Sub ThumbNailViewer1_MouseUp( _
ByVal sender As System.Object, _
ByVal e As System.Windows.Forms.MouseEventArgs) Handles ThumbNailViewer1.MouseUp
If e.Button = Windows.Forms.MouseButtons.Right And _
ThumbNailViewer1.GetThumbnailFromPosition(e.X, e.Y) IsNot Nothing Then
ContextMenuStrip1.Visible = True
Else
ContextMenuStrip1.Visible = False
End If
End Sub
You just have to subscribe to the MouseUp event for the Thumbnail control and add a ContextMenuStrip to your form. Then add a new menu item to the ContextMenuStrip. The Click event for that menu strip can hold the logic you write to remove a Thumbnail from the collection you are using to store the images you are hosting on the Thumbnail control. You can use the Viewer1.Images.RemoveAt() method, for instance (making sure you pass in the index of the selected Thumbnail).
rangasamy007: 3.I want to rearrange the ImageMan Viewer control items index. how to
implement that. suppose if the user want to move item3 (index position
2) to first (index position 0)
I don't have any example code to perform the actual exchanging of positions but I do have a blog post that describes how to wire up drag and drop on the Thumbnail control. From there you can come up with the logic to do the actual swapping. Here's a link to that post:
