[CLOSED] [1.0] MenuItem Click DirectEvent
Hi,
I have a problem with the following code. It worked well with 0.8.2.
It is context menu attached to TreePanel. When I click on a MenuItem it gives me "Request Failure", status code 500.
Code:
->TreePanel
...
<Listeners>
<ContextMenu Handler="#{cmenu}.node = node; node.select(); #{cmenu}.showAt(e.getPoint());" />
</Listeners>
->Context Menu
<ext:MenuItem ID="mnDisAbilita" runat="server" Text="disabilita voce di menu" Icon="ApplicationOsxDelete">
<DirectEvents>
<Click OnEvent="MB_Deny_Click">
<ExtraParams>
<ext:Parameter Mode="Value" Name="prmNodeIdDeny" Value="={#{cmenu}.node.id}">
</ext:Parameter>
</ExtraParams>
</Click>
</DirectEvents>
</ext:MenuItem>
->Code
protected void MB_Deny_Click(object sender, DirectEventArgs e)
{
string _id = e.ExtraParams["prmNodeIdDeny"].ToString();
if (_id == "0") return;
...
}
ViewState is enabled.
Do I have to change code?
Thanx
Matteo

Hi,
I am sure that status code 500 is consequence of server side exception. Try to set breakpoint inside MB_Deny_Click. Do you reach it?
Please create simple example which reproduces the problem

Hi Vlad,
no, I tried it, but it didn't reach server side code.
I'll prepare a simple example and post it.

Hi,
You can press Alt-Ctrl-E in VS to catch all exception (check checkbox for Common Language Runtime Exceptions). Then VS will show where exceptions occur

Hi Vlad,
I reproduced the error, the event stopped before entering server side code!?
However it was my fault, I decided to print in red the resource - treenode - not enabled.
To do this I added a tag to the node text.
In the code below, if you remove the tag it works fine.
Can you suggest an error safe solution to render the text node colored?

{
AsyncTreeNode asyncNode = new AsyncTreeNode();
asyncNode.Text = prefix + e.NodeID + i;
asyncNode.NodeID = e.NodeID + i;
e.Nodes.Add(asyncNode);
}
for (int i = 6; i < 11; i++)
{
Ext.Net.TreeNode treeNode = new Ext.Net.TreeNode();
//treeNode.Text = prefix + e.NodeID + i;
// It causes the error

e.Nodes.Add(treeNode);
}
}

{

this.TextField2.Text = "Deny Node: " + _id.ToString();

Hi,
I see, you have "A potentially dangerous Request.Form value was detected from the client" exception.
You can set ValidateRequest="false" for the Page or use Cls property for TreeNode to set red color
RE: [CLOSED] [1.0] MenuItem Click DirectEvent
Hi,
Or you can disable selection submit (see SelectionSubmitConfig property of the TreePanel, DisableAutomaticSubmit)
RE: [CLOSED] [1.0] MenuItem Click DirectEvent
Perfect, thanx Vald.
I'll post my code here:
Code:
CSS
.nodeDisabled .x-tree-node-anchor span{ color:Red !important; }
C#
...
asyncNode.Cls = "nodeDisabled";
Matteo
