RadUrid=xxx querystring - cannot find a part of the path error

After i select a file for upload, then hit a submit button (standard <asp:Imagebutton) - I get an error:

Cannot find a part of the path

and a querystring of RadUrid= has been added

Here is the aspx code:

<telerik:RadProgressManager runat="server" ID="RadProgressManager1" EnableMemoryOptimization="false" />

<telerik:RadAsyncUpload runat="server" ID="AsyncUp1"

OnClientFileUploaded="fileUploaded" TargetFolder="/images/BlogThumbs" AllowedFileExtensions=".jpg,.tif,.png,.gif,.jpeg" />

<telerik:RadProgressArea runat="server" ID="RadProgressArea1" />

and the fileUploaded script:

function fileUploaded(sender, args)

{

var name = args.get_fileName();

var $ = $telerik.$;

$(".info-panel").

append($("<div>" + name + "</div>")).show();

}

It was working - and i just upgraded to the newest 2010 version.

Any ideas?

ComboBox not passing selected value to content page

I am new to this stuff so I may be the issue. I have a master page and content page. On the master page I have a combobox.

<telerik:RadComboBox ID="cbBox" runat="server" AutoPostBack="True"

Height="120px"

ErrorMessage="No Items Available" Sort="Ascending">

</telerik:RadComboBox>

Fill by code behind(c#):

using (WorkFlowEntities items = new WorkFlowEntities())

{

this.cbBox.DataSource = from c in items.vw_UserAuth

where c.DomainName== "me"                                                         select new { c.Name, c.Item };

this.cbProject.DataTextField = "Name";

this.cbProject.DataValueField = "Item";

this.cbProject.DataBind();

this.cbProject.Items.Insert(0, new RadComboBoxItem("Select a item", string.Empty));

}

All of this works fine. I am trying to access the combobox from a content page but it always returns "" not null though. I am using this code to get the values:

private string getSelectedProject()

{

RadComboBox masterCombo = (RadComboBox)Master.FindControl("cbBox");

if (masterCombo != null)

{

return masterCombo.SelectedValue.ToString();

}

else

{

return null;

}

I know there is data being return because i tried hard coding the selected value.

RadAjax with Response.Write to download String into a Excel file

Hi!

I have the same problem:
My asp:ImageButton is inside a telerik:RadAjaxManager and do the same code:

HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.AddHeader( "content-disposition", string.Format( "attachment; filename={0}", "ElencoCandidati.xls" ) );
HttpContext.Current.Response.ContentType = "application/ms-excel; charset=utf-8";
HttpContext.Current.Response.Write( wResult );
HttpContext.Current.Response.End();
HttpContext.Current.Response.Flush();

Without the telerik:RadAjaxManager work fine but when i run my website with a telerik:RadAjaxManager I have the same error:

Line: 938
Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '<html xmlns:o="urn:s'.

What can I do?

Thanks in advance!

How do I stop the client side filtering?

Hi, I am getting a double filtering effect happening. Once on the server side and then one more time on the client side. This double filtering wouldn't be an issue except for one of my columns (Description) is 2000 characters long so I only pass back the first 200 characters. If the data I filtered on is after the first 200 characters then the client side filter removes the row.

I do server side filtering by using the datasource selecting event:

protected void objItems_Selecting(object sender, ObjectDataSourceSelectingEventArgs e)

{

e.InputParameters["sortExpression"] = RadGrid1.MasterTableView.SortExpressions.GetSortString();

e.InputParameters["filterExpression"] = RadGrid1.MasterTableView.FilterExpression;

if (e.ExecutingSelectCount)

{

// count is done last

//RadGrid1.MasterTableView.FilterExpression = "";

// while using the above line worked it failed when going from page to page

}

else

{

// selection is done first

}

} 
 

 

public IList get(int catalogueId, string sortExpression, string filterExpression, int maximumRows, int startRowIndex)
 
{

...

RadTreeView drag and drop scrolling

Hello,

We have some trees with lots of nodes. Drag and drop is enabled so users can re-order the nodes. When a user wants to drag a node from the top of the list to the bottom, the page doesn't automatically scroll. They have to drop the node halfway and manually scroll to continue dragging. Is there anyway to have the page automatically scroll when a user is dragging a node up or down a long tree?

Thanks!
