Tree Node Selection

[Satish]

Hi,
How can I Make Tree should always have foucs (Node cannot loose the focus (blue background color). Focus should not go, even if user clicks on any control on the form.

Thanks
Satish

Set the HideSelection property of the TreeViewAdv to false.

Hi,

Once again, thanks a lot for your response, Sean.

Doing the following :
this.treeViewAdv1.HideSelection = false;

will ensure that the selected node is always highlighted. But when the TreeViewAdv loses focus, the selection rectangle gets grayed out instead of being blue. Please let me know if this works for you.

Hi Satish,

Yes, you could do so by setting the following properties :

this.treeViewAdv1.InactiveSelectedNodeBackground = new Syncfusion.Drawing.BrushInfo(System.Drawing.Color.MediumBlue);

this.treeViewAdv1.InactiveSelectedNodeForeColor = SystemColors.ActiveCaptionText;

Please try this and let me know if this works for you. Thanks for considering Syncfusion products.

Hi Guru Patwal,

Can you help me in following code:

***************************

private void buttonFindInstruments_Click(object sender, System.EventArgs e)
{
bool found=false;
for (int index = 0 ; index < treeViewAdvProfiles.Nodes.Count ; index++ )
{
if (searchNode(treeViewAdvProfiles.Nodes[index]))
{
found=true;
break;
}
}
if (found)
{
MessageBox.Show("found");
}
else
{
MessageBox.Show("not found");
}
}

public bool searchNode(TreeNodeAdv treeNode)
{
string nodeText;
bool found=false;

for (int index = 0 ; index < treeNode.Nodes.Count ; index++ )
{
nodeText = treeNode.Nodes[index].Text;
try // temporarily written
{
if (String.Compare(nodeText, comboBoxInstruments.Text, true)==0)
{
found=true;

// Highlight Node
break;
}
else
{
searchNode(treeNode.Nodes[index]);
}
}
catch(Exception ex)
{
ex=ex; // just to trace
}
}
return (found);
}

***************************

The above searches a node in the treeview for comboBoxInstruments.Text. This code works fine, except, pointing and highlighting the node which is found (matched).

I want to write the required code at comment (// Highlight Node)

Thanks,

Found solution for abobe issue:

just place following code at comment (// Highlight Node)

treeViewAdvProfiles.SelectedNode = treeNode.Nodes[index];
treeViewAdvProfiles.Focus();
