Tree View ImageList and double click

[rfazendeiro]

Hi to all,

 

when i double click in my tree view i change the image that displays, indicating a diferente state of that node. The images are in my imageList, and by default the images index is 0.

 

Ok. So far so good. I have 2 main problems that are tied together.

 

1) When i double click the image change only appears when i select another node.

 

2) When i select a node, the image reverts back to the image that existes by default. When i select another node the image returns to what i had there.

 

 

so what can i do to 1) change the image imediatly when i double click the node and 2) how can i, when i select a node, prevent i to revert to the original image

 

 

thx to all

so after some struggle with the treeview i resolved the problem only to create a new one.

 

For the 1) problema when i double clik it automaticly changes the image to the next in the image list so its done

 

for the 2) problem when i interare throught the nodes in the tree view it no longer changes to the default image of the tree view so its done.

 

 

To resolve the problems abouve i have to do this

 

private void trvModulos_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
      if (this.trvModulos.SelectedImageIndex != e.Node.ImageIndex)
      {
this.trvModulos.SelectedImageIndex = e.Node.ImageIndex;
      }
}

 

basicly what i do is change the defaut tree view imagem for the one that the node contains. But the problem is that this refreshes the entire tree view closing all expanded nodes and blinks a little making it wierd.

 

Is there any way to stop the tree view to refresh when i do this ??

 

this.trvModulos.SelectedImageIndex = e.Node.ImageIndex;

 

 

thx for the help
