Binding TreeView ImageURL with ObjectDataSource, it's possible?

Hi,

I tried to bind ImageUrl property with ObjectDataSource without success. I look all demo and exemple for this work and i can't find how to bind this property.

My treeView display the text and build good structure, mais i can't set ImageUrl from my object.

I tried this in the markup

ImageUrl="Image"<telerik:RadTreeView ID="rtvNavigation" runat="server"
    MultipleSelect="false"
    Font-Size="9pt"
    Height="94%"
    Width="100%"
    DataSourceID="ObjectDataSource1"
    DataTextField="Description"
    DataFieldID="ID"
    DataFieldParentID="ParentID"
    AllowNodeEditing="false"         
    ImageUrl="Image"       
    OnNodeClick="rtvNavigation_NodeClick">
</telerik:RadTreeView>

and onNodeDataBound event, i can't set this imageURL because the ID is always empty.

Thank you for help!

[Solved] RadScheduler recursion 'End after x occurrences' bug?

Hi guys,

I'm not sure if this has already been addressed or identified, but I'd like to point out an issue that I can reproduce on your demo page:

Reproduction steps:
1. Go to your demo page: http://demos.telerik.com/aspnet-ajax/scheduler/examples/overview/defaultcs.aspx
2. Click on an available time slot to create an appointment and click 'Options' to bring up the advanced form
3. Give the appointment an arbitrary subject, and check the 'recurrence' box
4. Select and insert '1000' into the 'end after ... occurrences' box
5. Click Save
6. Reopen the appointment ('edit entire series')

Expected results: The 'end after' box still has the value of 1000.
Actual results: The 'end after' box has the value of 1.

Comments:
It works as expected for values up to 999. It seems to run into a problem when the thousands separator comes into play (i.e. the text is formatted as "1,000" when 1000 is entered into the box. As such, I imagine it may have something to do with regional settings and the way numbers are parsed and formatted. At a lower level, it seems that calling:

$find("<recurrenceEditorId>").get_recurrenceRule().get_range().get_maxOccurrences()

returns the incorrect value. Sadly I don't have time to go deeper into the definition of this function, but I would appreciate it if you could kindly let me know:
* Is this indeed a bug?
* Is it a known bug?
* Are there any workarounds?
* Any estimate on when a fix may be released?

Thanks for your time.

Cheers,
Sam

Upload: Uncaught TypeError: Cannot call method 'get_selectedItem' of null

Hi,

When I try to upload a file using FileExplorer, the update panel keeps showing long after the file upload.

In the Chrome console, this script error appears:

Uncaught TypeError: Cannot call method 'get_selectedItem' of null

Here's the declaration of the FileExplorer:

<telerik:RadFileExplorer ID="ExplorerExportTemplates" runat="server" Width="600px" Height="400px"

Skin="Metro" Configuration-AllowFileExtensionRename="False" Configuration-AllowMultipleSelection="False"

AllowPaging="true" EnableOpenFile="true" EnableAsyncUpload="True">

</telerik:RadFileExplorer>

Here's the code-behind:

string[] paths = new string[] { Page.ResolveUrl(fullPath) };

ExplorerExportTemplates.Configuration.ViewPaths = paths;

ExplorerExportTemplates.Configuration.UploadPaths = paths;

ExplorerExportTemplates.Configuration.DeletePaths = paths;

ExplorerExportTemplates.Configuration.EnableAsyncUpload = true;

ExplorerExportTemplates.Configuration.MaxUploadFileSize = 104857600;

ExplorerExportTemplates.Configuration.AllowFileExtensionRename = false;

ExplorerExportTemplates.Configuration.AllowMultipleSelection = false;

ExplorerExportTemplates.EnableCreateNewFolder = true;

ExplorerExportTemplates.EnableCopy = false;

ExplorerExportTemplates.ExplorerMode = Telerik.Web.UI.FileExplorer.FileExplorerMode.FileTree;

ExplorerExportTemplates.Configuration.SearchPatterns = new string[] { "*.xls", "*.xlsx" };

ExplorerExportTemplates.Configuration.ContentProviderTypeName = typeof(Telerik.Web.UI.Widgets.FileSystemContentProvider).AssemblyQualifiedName;

Any ideas?

Thanks,

Ajit

invalid postback argument after custom filtering

Hi

I have radgrid with custom filtering:

<script type="text/javascript">

function IconsComboBoxChanging(sender, eventArgs) {

var item = eventArgs.get_item();

if (item != null) {

var input = sender.get_inputDomElement();

input.value = "";

input.defaultValue = "";

}

function DropDownFilterLoad(sender) {

sender.set_text("");

var itm = sender.get_items();

var selected = itm.getItem(sender._selectedIndex);

var img = selected.get_imageUrl();

var input = sender.get_inputDomElement();

SetBackground(input, img);

}

</script>

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="true" OnNeedDataSource="CorrectionsGrid_NeedDataSource" [...]>

[...]

<Columns>

<telerik:GridTemplateColumn UniqueName="CorrectStatus" HeaderText="Status" HeaderStyle-Width="55px" Resizable="false" DataField="CorrectionAcceptState">

<ItemTemplate>

<asp:Image [...] />

</ItemTemplate>

<FilterTemplate>

<telerik:RadComboBox ID="StatusFiletCB" Width="45px" AppendDataBoundItems="true" DropDownWidth="205px" NoWrap="true" runat="server" OnSelectedIndexChanged="CorrectStatusFilterChange" AutoPostBack="true" AllowCustomText="false" OnClientSelectedIndexChanged="IconsComboBoxChanging" OnClientLoad="DropDownFilterLoad">

<Items>

<telerik:RadComboBoxItem Value="0"[...] />

<telerik:RadComboBoxItem Value="1"[...] />

<telerik:RadComboBoxItem Value="2" [...] />

</Items>

</telerik:RadComboBox>

</FilterTemplate>

</telerik:GridTemplateColumn

>

<telerik:GridTemplateColumn AllowFiltering="false" UniqueName="ActionColumn" HeaderText="" HeaderStyle-Width="60px"
    Resizable="false" Visible="false">
    <ItemTemplate>
       <asp:ImageButton CommandName="Reject" runat="server" CommandArgument='<%# Eval("CorrId") %>' Visible='<%# this.IsUserAllowedToAccept() %>' [...] />
    </ItemTemplate>
</telerik:GridTemplateColumn>

[...]

</Columns>

</telerik:RadGrid>

Code behinde:

protected void CorrectionsGrid_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

CorrectionsGrid.DataSource = new MyDataContext().Corrections;

}

private int? GetValueOfCorrectionAcceptStateFilter()

{

var regSearch = Regex.Match(CorrectionsGrid.MasterTableView.FilterExpression, @".*$it\.CorrectionAcceptState = (?<filterVal>[1-3])$.*");

if (regSearch.Success)

return Int32.Parse(regSearch.Groups["filterVal"].Value);

else

return null;

}

protected void CorrectStatusFilterChange(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

string filterExpression = CorrectionsGrid.MasterTableView.FilterExpression;

var currentcFilter = GetValueOfCorrectionAcceptStateFilter();

if (currentcFilter.HasValue)

filterExpression = filterExpression.Replace("(it.CorrectionAcceptState = " + currentcFilter.Value + ")", string.Empty);

if (Int32.Parse(e.Value) > 0)

filterExpression = (filterExpression.Trim().Length > 0 ? filterExpression + " AND " : "")

+ "(it.CorrectionAcceptState = " + e.Value + ")";

CorrectionsGrid.MasterTableView.FilterExpression = filterExpression;

CorrectionsGrid.MasterTableView.Rebind();

}

everything works fine until I set the filter and call out rejection - invalid postback or callback argument. where making a mistake?
