Refresh RadTreeView via RadAjaxManager causes loss of functionality

Hello,

I have a control that loads a RadTreeView using an object as the source and performing on-demand loading of child nodes via the OnNodeExpand event. I also use a RadWindow to allow users to edit the tree nodes. When the user saves their changes on the RadWindow, it fires an ajax event using javascript which then uses an ajax request to update the node in the tree. This is working very nicely.

However, when the user finishes editing and closes the RadWindow the RadTree no longer functions properly. The OnNodeExpand event is no longer firing when trying to expand a node and the OnClientMouseOver I was using to display tooltips is not effective below the first level of nodes. I've tried adding the NodeExpand event handler back in after the update just in case it's getting lost somewhere, but this doesn't seem to work.

Any ideas what I'm doing wrong?

Thanks,
Courtney

Here's my ajax request code

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

string[] values = e.Argument.Split(new[] { "|" }, 2, StringSplitOptions.None);

string nodeId = values[0];

string nodeText = values[1];

foreach (RadTreeNode node in GroupTree.Nodes)

{

if (UpdateNode(node, nodeId, nodeText))

break;

}

GroupTree.NodeExpand += (GroupTreeOnNodeExpand);

}

private static bool UpdateNode(RadTreeNode node, string nodeId, string nodeText)

{

if (node.Attributes["id"] == nodeId)

{

node.Text = nodeText;

return true;

}

foreach (RadTreeNode childNode in node.Nodes)

{

if (UpdateNode(childNode, nodeId, nodeText))

return true;

}

return false;

}

Treeview item has a problem in Download File

Hello,
Actually, I have some problem with the Treeview item in particular onClientContextMenuItemClicking as shown below:



function

onClientContextMenuItemClicking(sender, args) 

{

var menuItem = args.get_menuItem();

var node = args.get_node();

menuItem.get_menu().hide();

switch (menuItem.get_value()) {

case "SaveAs":

Xlate.Web.Translation.service.ResourceFilesService.ExportResourceFile('108', PassServiceHandler, FailServiceHandler);

break;

}

Save As menu item is supposed to save resx file [RESOURCE FILE in DOTNET]; it calls a webs service to get the file from the DB, and Download the file, but the below code didn't work out in this case, but when i tried it out without Ajax or Telerick controls, I could work it out:

[WebMethod()]

public void ExportResourceFile(string fileId)

{

List<ISearchResult> searchResults;

SearchCriteria searchCriteria;

try

{

searchCriteria = new SearchCriteria();

searchCriteria.ResourceFileID = int.Parse(fileId);

searchCriteria.SearchOption = SearchType.ResxKey;

ResourceFile resourceFile = ResxFileManager.CreateResourceFile(searchCriteria);

MemoryStream memoryStream = new MemoryStream();

memoryStream = Manager.GenerateResxSourceCode(resourceFile);

memoryStream.Position = 0;

DownloadFile(memoryStream,resourceFile.Name);

}

catch (Exception ex)

{

// set exception message

string errorMessage = String.Format("Failed to export resource fileid ={0}, error:{1}", fileId ,ex.Message);

// trace call

TraceUtil.Write("ResourceFilesService::ExportResourceFile", "Exception occured [{0}]", errorMessage);

// publish and rethrow the exception

BusinessException businessExc = new BusinessException(errorMessage, ex);

throw (businessExc);

}

private void DownloadFile(MemoryStream memoryStream,string fileName)

{

byte[] byteArray = memoryStream.ToArray();

memoryStream.Flush();

memoryStream.Close();

HttpContext.Current.Response.Clear();

HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=test.resx");

HttpContext.Current.Response.AddHeader("Content-Length", byteArray.Length.ToString());

HttpContext.Current.Response.ContentType = "application/octet-stream";

HttpContext.Current.Response.BinaryWrite(byteArray);

}

DownloadFile method should force the Browser to open Save Dialog File, is there anything wrong with the code above, Could you please Help.

Regards,
Hanan

RadGrid popup edit form - size problems

Hi,

Please see attached image.

I'm using the popup edit form to insert/update records in a radgrid. The first time the edit form is opened the controls it contains flow outside the form bounds.

If I close and reopen the edit form, it sizes correctly. Any ideas?

Thanks,

James

IE8 Compatibility

Hello,

Can you please confirm that Radcontrols for ASP. NET AJAX Q3 2009 SP2 - version 2009.3.1314 is IE8 compatible?
We are switching to windows 7/ie8 environment soon and on the preliminary testing we are seeing the controls layout look very different in IE8.
Please advise.

Thanks,

http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx

And now it works perfectly in IE but in Firefox it makes the browser not responding. Are you aware of this issue?

This is just a copy/paste operation with the same data .. i even created DB with identical tables structure.

Please let me know if i can fix this issue somehow.

Thanks

[Solved] Can you seperate out the icon sprite please?

The built-in icons are SUPER handy, but the single 30k sprite is WAY WAY to big.

Even just separate into two sprites...large icons and small icons...like if I just need one small checkmark and X, on the entire page\app, a 30k sprite ads a lot of overhead for me. I'm not sure where I'd ever need to intermingle the icons (large and small)...buttons on a page should be consistent. So you'd have large OR small buttons?

Ideally I'd like to see 4 sprites
1) Small Basic (checks, and X's...common stuff)
2) Small Tools (checkout, rss, etc...fringe stuff)
3) Large Basic
4) Large Tools

Could you at least consider it? :) I'm seeing a noticeable "pop" when my buttons load.

UserControl event fires but properties are empty

Hi

I have a simple grid with no edit mode. See Pic at this URL
http://screencast.com/t/X1XtwRegixy

I want the user to be able to switch "Chart" without going into an edit mode.

I therefore created a user control made from a a radcombo which populates the combo and has an event attached to it which calls a method that updates the charttype in the database.

I have an additional property in my usercontrol which is the Primarykey (seriesID) required create the obj and run the update.

<telerik:GridTemplateColumn HeaderText="Chart" UniqueName="ColChart">

<ItemTemplate>

<uc3:kpidropdownchart ID="kpiDropDownChart1" runat="server" seriesid='<%#Bind("SeriesID") %>' selectedChart='<%#Bind("ChartType") %>'/>

</ItemTemplate>

</telerik:GridTemplateColumn>

The control populates correctly (I even added the primarykey into the item.text to show it is there - see pic above)
When The selected index is changed the event fires (pasisng all of the argument including old and new values) inside the user control, but all of the properties in the usercontrol now are empty ie the primaryKey (seriesID) required to run call my update method.

Any idea what I am doing wrong?

Imports Telerik.Web.UI

Public Class kpiDropDownChart

Inherits System.Web.UI.UserControl

Private _seriesid As Integer

Private _selectedChart As String

Private _chartid As Integer

Public Property SeriesID() As Integer

Get

Return (_seriesid)

End Get

Set(ByVal value As Integer)

_seriesid = value

End Set

End Property

Public Property selectedChart() As String

Get

Return (_selectedChart)

End Get

Set(ByVal value As String)

_selectedChart = value

End Set

End Property

Protected Sub ddAddFieldChart_PreRender(ByVal sender As Object, ByVal e As EventArgs) Handles ddAddFieldChart.PreRender

Dim chartTypeTable As DataTable = kpicommonListFns.GetTimeChartList

Dim row As DataRow

For Each row In chartTypeTable.Rows

Dim CItem As RadComboBoxItem = New RadComboBoxItem

CItem.Text = row("Description") & _seriesid

CItem.Value = row("chartRef")

CItem.ImageUrl = "~/images/chartImages/" & row("IconName")

ddAddFieldChart.Items.Add(CItem)

Next

ddAddFieldChart.SelectedValue = _selectedChart

End Sub

Private Sub ddAddFieldChart_SelectedIndexChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles ddAddFieldChart.SelectedIndexChanged

'###### when this even fires _seriesid = nothing ####################

Dim thisSeries As kpiChartSeries = New kpiChartSeries(_seriesid)

thisSeries.SetChartType(ddAddFieldChart.SelectedValue)

End Sub

End Class

Thanks

Urgent Fix For Rad Grid Detail Table Issue

Hi ,

I need to allow scroll for Detail Table along with have static header . I have implemented solution based on the below link.
http://www.telerik.com/community/code-library/aspnet-ajax/grid/separate-scrolls-for-inner-tables-in-hierarchical-grid.aspx

Since detail table have large amount of data, when user scrolls down, he will not be able to see the Detail table header.
So please suggest the solution for the problem or Is there any work around for this?
Can we use Radgrid inside a RadGrid instead of DetailTable to solve this problem?

I have attached the screenshot for your reference. Screenshot1 shows the initial look of the grid and Screenshot2 shows after scrolling the DetailTable.

It is very urgent and important for me.Please reply as soon as possible.

when data is more in the grid user gets to see 4 scrolls. which is like confusing ... please refer the screen shot.

Thanks,
Nagendra
