[Solved] OnContextMenuItemClick not fired when using Custom RadTreenNodes

So I have been working with RadTreeView and it's context menu with succes, to test if it could solve a problem of mine. Next problem was that the RadTreeNodes could not contain enough information, so I created my own TreeNodes, and extended those to RadTreeNode. I could create and add the new Nodes to the RadTreeNode without any problems.

But when I tested my treeview, it's showed all nodes i added. When i rightclick the contextmenu pops up, but when clicking on any menuitem, the OnContextMenuItemClick event is not fired. I tried remove all of my nodes, and only add one original RadTreeNode. This works.

I found out that the problem also affects OnNodeDrop and OnNodeEdit events.

It sounds like using costum nodes corrupts some event system. Is this true?

Here are my code snippets:

Custom node:

public class ReportTreeNode : RadTreeNode

{

public ReportTreeNode(String text) : base(text)

{

Locked = false;

}

public ReportTreeNode(String text, String value) : base(text, value)

{

Locked = false;

}

public ReportTreeNode(String text, String value, String image)

: base(text, value)

{

Locked = false;

ImageUrl = image;

}

public ReportTreeNode(String text, String value, String image, String type)

: base(text, value)

{

NodeType = type;

Locked = false;

ImageUrl = image;

}

public bool Locked { get; set;}

/// <summary>

/// The report node type. eg. Section, textarea, pagebreak etc.

/// </summary>

public String NodeType { get; set; }

/// <summary>

/// Returns the depth location of the node

/// </summary>

/// <returns></returns>

public int getDepthOfNode()

{

int result = 0;

foreach (char c in FullPath)

{

if (c == '/')

result++;

}

return result;

}

TreeView:

<telerik:RadScriptManager ID="scriptmanager" runat="server" />

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" ><img src="anidog2.gif" /></telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">

<asp:Literal ID="statusMessage" runat="server"></asp:Literal><br />

<telerik:RadTreeView ID="template" runat="server" EnableDragAndDrop="true" EnableDragAndDropBetweenNodes="true"

OnContextMenuItemClick="dynamicMenu_ContextMenuItemClick" OnNodeDrop="dynamicMenu_OnNodeDrop" OnNodeEdit="dynamicMenu_OnNodeEdit" AllowNodeEditing="true" OnLoad="templateOnInit">

<ContextMenus>

<telerik:RadTreeViewContextMenu>

<Items>

<telerik:RadMenuItem Text="Add" Value="none" ImageUrl="application_add.png">

<Items>

<telerik:RadMenuItem Text="Section" Value="add:section" ImageUrl="section.png"/>

<telerik:RadMenuItem Text="Textarea" Value="add:textarea" ImageUrl="testArea.png"/>

</Items>

</telerik:RadMenuItem>

<telerik:RadMenuItem Text="Add Custom Section" Value="addCustom" ImageUrl="application_add.png" runat="server" />

<telerik:RadMenuItem Text="Delete" Value="delete" ImageUrl="application_delete.png" runat="server" />

</Items>

</telerik:RadTreeViewContextMenu>

</ContextMenus>

</telerik:RadTreeView>

</telerik:RadAjaxPanel>

And here I add a node to the treeview:

protected void templateOnInit(object sender, EventArgs e)

{

if(IsPostBack)

return;

template.Nodes.Clear();

ReportTreeNode report = new ReportTreeNode("Report", "report", picturepath + "/report.png", "report");

report.Locked = true;

template.Nodes.Add(report);

return;

}

if anyone have an answer to this, I would be happy.

RadGrid with 3 footers

Hi All,

I (may) have a problem with an application containing a radgrid.
Because I do not know the number of columns at designtime, I declared the radgrid in the aspx file without columns, and build the grid structure in the code behind (In the NeedDataSource() event after data is fetched from the database).

In order to create 3 footerrows, my plan was to create a footertemplate, but I have read that this must be done in the page_init event.
During page_init however, I do not know the number of columns to create .... so I was stuck here.

I may have found a solution that works (Inspired from another thread about 2 HeaderRows).
During Grid.PreRender i add additional footerrows. It seems to work ok, but I am not sure if this is reliable.

Any comments ?

Thanks.

Here is the code:

Protected Sub Grid_TimeSheet_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Grid_TimeSheet.PreRender

AddFooterRow(1)

AddFooterRow(2)

End Sub

Protected Sub AddFooterRow(ByVal marker As Integer)

' get the current footer

Dim footer As GridItem() = Grid_TimeSheet.MasterTableView.GetItems(GridItemType.Footer)

' get the current TFoot element

Dim foot As GridTFoot = CType(footer(0).Parent.Controls(0).Parent, GridTFoot)

Dim LastFooterPos As Integer = 0

For n = 0 To foot.Controls.Count - 1

If TypeOf (foot.Controls(n)) Is GridFooterItem Then

LastFooterPos = n

End If

Next

Dim newFooterItem As GridFooterItem = New GridFooterItem(Grid_TimeSheet.MasterTableView, 0, 0)

PopulateNewFooterItem(newFooterItem, foot.Controls(LastFooterPos), marker)

foot.Controls.AddAt(LastFooterPos + 1, newFooterItem)

End Sub

Protected Sub PopulateNewFooterItem(ByVal footer As GridFooterItem, ByVal existingfooter As GridFooterItem, ByVal marker As Integer)

For Each fc In existingfooter.Cells

Dim new_fc As TableCell = New TableCell

new_fc.Text = marker.ToString()

footer.Cells.Add(new_fc)

Next

End Sub

Insert and Cancel buttons in Telerik Popup Window

We have a telerik popup window with text fieds and Save/Cancel buttons.

We have these issues:

1. If I press enter key it takes back to the parent window
2. If I set default button to panel, either Save or Cancel is working

Ex:

I have telerik popup window with Save set as default button to the panel.

Upon hitting enter key when focus is on Save button the record is saved.

Upon hitting enter key when focus is on Cancel button the popup window is to be closed, but it is saved!

Any workaround please?!

Thank you

Regards
Raj

[Solved] AdvancedInsertTemplate Through JS

I am using the scheduler a bit differently then how it was originally intended. We are using it to schedule employees for shifts to work. Most employees work the same shift, so instead of manually going through and adding in each employee to a time I created a form that will allow you to select multiple employees, multiple days, and a start and end time. I would like to move this to the AdvancedInsertTemplate instead of through a radwindow. My only issue with doing this is that I see no way of calling the command that shows the AdvancedInsertTemplate . Is there a command I am missing? I have disabled the insert by clicking on a time as this isn't valid for the application I have created.

Validation Controls in Telerik Panel

Hi,
Am Very new to Telerik and ASp.net.
I am facing problems with Custom validators in Telerik panel.
I need to throw an error in the validation summary when the custom validator is fired. The custom validator has validation method in server side.
The problem is, the custom validator successfully displays errors in validation summary in case of normal page.
But since the text boxes are in telerik panel the custom validator can only dispaly messages inline, where the validator is present(Text attribute of custom validator). The error message attribute of custom validator, which is supposed to show the message in validation summary, does not work.
Pl help, as dispalying the message in validation summary is the requirement.

Note: Required field validator and regular expression validator works fine by displaying messages in validation summary in telerik panels. Also, I have associated the validators with validation groups of validation summary for required field, regular expression and custom validators.

RadEditor with embedded video hangs IE6

Hi,

I am using RAd Editor on MVC Application.
All seems fine but I get the following error when I try to submit the page
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

I have looked around for the solution and tried all possible solution but nothing seems to work.

Can anyone please suggest how to work around this problem?
