Textboxex in a RadTreeView

[Philip Saltskog]

I'm using version 2008.2.820.35 and I've successfully add textboxex to each node and also a literal text there too, but I can't get it out there with findcontrol??

Dim nodeCollection As System.Collections.Generic.IList(Of RadTreeNode) = R1.CheckedNodes
Dim node As RadTreeNode
For Each node In nodeCollection
    Dim testCount As Integer = node.Controls.Count
    Dim boxBanner As TextBox = node.FindControl("boxBannerID" & node.Value)
next node

Any ideas why I don't get it from the node in the IList?

/Thanks

Hi Philip Saltskog,

It is difficult to say why this is happening only by looking at this code.

Could you provide more information such as how the TextBoxes are added to Nodes? How are their IDs generated?

Thank you in advance.

When I'm create the box I use this code.

 

Dim myBox As New TextBox
myBox.ID = "boxBannerID" & dbRow("ID")
node.Controls.Add(myBox)

dbRow is a datarow in a datalist from DB.

.aspx page
<input name="R1$i0$i0$boxBannerID79" type="text" value="3" id="R1_i0_i0_boxBannerID79" class="brodtext" style="width:20px;" />

Hello Philip Saltskog,

Thank you for the additional information.

Controls added to Nodes in this way should be added on each postback, and not only on the first page load. Could you please make sure that this is realized in your case?

You can avoid this issue, however, by using dynamic runtime Templates as shown in this help article.

I'm now using the template class, but I'm still not get anything with findcontrol?

Dim boxBanner As TextBox = node.FindControl("boxBannerID" & node.Value)

For each node i call

template.InstantiateIn(node)

but when I'm use postback it's empty. Even if I call my sub from a postback it's empty of controls. I only get the node control here.

Any ideas?

/Thanks

I solved it with request.form :)

Dim boxBanner As String = Request.Form(node.UniqueID & "$boxBannerID" & node.Value)

When the postback come the textbox is disappeared, but I think you have a solution on this soon :)!?? Might allready have any solution?

That important thing is I get the datavalue from the textbox :)

/Thanks

Found another strange behavior.

When I add controls to the node I get wrong node.value on the checked nodes. If I checked two nodes and use

Dim nodeCollection As System.Collections.Generic.IList(Of RadTreeNode) = R1.CheckedNodes

I get wrong node on the child node.

I think this is instable and I will wait till Telerik release som support for controls in a node...

Telerik: Do you know when you will support that?

/Thanks

Hi Philip Saltskog,

Controls are supported by RadTreeView and the best approach is to use Templates.

Regarding your case, without additional information I will be unable to determine why Templates do not work as expected at your side.

Could you please open a formal support ticket and send us the problematic pages (or project) there (including the second issue you are experiencing)?

We will inspect the files and hopefully will provide solutions or temporary workarounds.

Thank you in advance for your co-operation.
