RadTreeView Only display ROOT nodes

Hello, i have really simple RadTreeView control.

but there is an issue, nodes only display if they have "0" ParentID. I put the code like telerik's examples and also table content is correct.

Why i cant put any child nodes which their ParentID is ParentID > 0

var ds = db.Finding.AsQueryable().ToList();

treeView.DataTextField = "VulnerabilityCode";

treeView.DataValueField = "ScanId";

treeView.DataFieldID = "Id";

treeView.DataFieldParentID = "ParentId"; // only shows where this value is ZERO

treeView.DataSource = ds;

treeView.DataBind();

<telerik:RadPane runat="server" Scrolling="None">

<telerik:RadSplitter runat="server" Orientation="Horizontal">

<telerik:RadPane runat="server">

<telerik:RadTreeView ID="RadTreeView2" IsExpanded="True" runat="server" Skin="WebBlue" Height="600px" Width="100%">

</telerik:RadTreeView>

</telerik:RadPane>

Background colour not applied to Alternate rows in Boostrap Skin

Hi

I have a simple Rad grid using the Bootstrap skin.

Based on the data I'm using the ItemDataBound to change the row COlour, however its not being applied to Alternate rows.

How can I fix this?

Here is my code:

Protected Sub rgHousekeeping_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgHousekeeping.ItemDataBound

If TypeOf e.Item Is GridDataItem Then

Dim RowDataItem As GridDataItem = CType(e.Item, GridDataItem)

Dim TaskComplete As System.Web.UI.WebControls.Image = DirectCast(RowDataItem("TaskComplete").Controls(0), System.Web.UI.WebControls.Image)

If CBool(e.Item.DataItem("TaskComplete")) Then

TaskComplete.ImageUrl = "Content/Images/Tick_24.png"

Else

RowDataItem.BackColor = Drawing.ColorTranslator.FromHtml("#ff7474")

End If

End Sub

Rendering Custom Elements in the Editor

We are currently rebuilding a module in one of our applications that takes a document template, replaces marked placeholders within the template with specific data , and then allows the user to download the file as a word document.

The user would like to be able to edit these templates online, before they are rendered. One key feature that we need to include is conditional blocks - certain sections of the template will only be rendered if the data in the system meets specific conditions. We need to make these conditional blocks as user friendly to edit as possible.

What i have envisaged is creating a custom module for the RadEditor that can be used to select and insert conditional blocks, that the user can then edit to their liking. It is important that the end user (who is non technical) can identify and understand these conditional sections easily and click on them to load them in the custom module editor.

I notice i can create custom content filters in javascript that can hook into the rendering of the designer/html view, which would seem appropriate for this kind of solution.

The problem is that there is no documentation on the customFilter object - where can i find more info on how to use this?

Namespace Telerik.QuickStart can not found

Hi Telerik,

I want to use your filtered combobox as given in web link: http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/filteringcombo/defaultcs.aspx

But I am getting "CS0234: The type or namespace name 'QuickStart' does not exist in the namespace 'Telerik' (are you missing an assembly reference?)" error.

I tried to find QuickStart in my telerik package but can not found this file/dll. Please help me to implement the required control and get the proper dll.

What's the javascript equivalent of MasterTableView.IsItemInserted =False

I've done some server side validation on Insert, and then called the confirmation box

RadWindowManager1.RadConfirm("Are you sure?", "confirmInsertCallBackFn", 330, 100, null, "System Alert");

So on my client side I can cancel the user response ...

function confirmInsertCallBackFn(arg) {
if (arg) {
$find("<%=RadGrid1.ClientID%>").get_masterTableView().fireCommand("InitInsert", "");
### NEED TO CLOSE THE INSERT FORM ###
}
}

The only issue is that the the Insert form doesn't close when the RadConfirm is OK. What is the java script equivalent of "RadGrid1.MasterTableView.IsItemInserted =False" in order to close the Insert form.

I found general guidance here, but the cancelInsert() call actually cancels the Insert altogether and closes the insert form, rather than just close the form.

https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/client-side-programming/gridtableview-object/methods/cancelinsert

$find("<%=RadGrid1.ClientID%>").get_masterTableView().cancelInsert();

Limit on # of nodesWe are

We are implementing a treeview where the # of nodes could exceed 5000 nodes. We are using ServerSideCallBack to populate the children nodes and have noticed that the treeview control stops responding if the # of nodes exceeds 800-900. After a while an error message pops up "A script on this page is causing internet explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script". If I select "No", sometimes (based on the # of nodes) it loads the children and at other times it just freezes.

What would suggest in this scenario ? Is there a way that we could load the children in smaller chunks ? Let us know.
