Hello Gurus,

I am giving Path Dynamically, i am getting the following exception:

'C:/TestApplication.WebApp/UserWebDrive/acd8e7a9-1454-43d8-9679-272969ee317c/Images' is a physical path, but a virtual path was expected.

here is the code i am using:
-------------------------------------

<telerik:RadFileExplorer runat="server" ID="FileExplorer1" Width="520px" Height="520px"
OnClientItemSelected="OnClientItemSelected" AllowPaging="true" PageSize="10">

</telerik:RadFileExplorer>

string Path = Server.MapPath("~/MagicWebDrive/" + UserID);
string[] arrFiles = System.IO.Directory.GetDirectories(Path);
for (int i = 0; i < arrFiles.Length; i++)
{
FileExplorer1.Configuration.ViewPaths = arrFiles.ToArray();
FileExplorer1.Configuration.DeletePaths = arrFiles.ToArray();
FileExplorer1.Configuration.UploadPaths = arrFiles.ToArray();
}

Thanks in Advance

GridCalculatedColumn causing error when last row deleted in RadGrid

Hello,

I recently made a change to a RadGrid by adding a Calculated column. My data source is an in-memory dataset. When I delete the final row in the grid and remove it from the dataset (in the code behind) I receive the following error:

Sys.WebForms.PageRequestManagerServerErrorException: Exception has been thrown by the target of an invocation.

I was able to get a little bit more information by adding a Rebind() to my grid in the deletion method. I received the following inner exception
{"This row has been removed from a table and does not have any data. BeginEdit() will allow creation of new data in this row."}

I have further proven the calculated field is the cause, by simply removing the GridCalculatedColumn and re-running the code with no issues. The error return as soon as the calculated grid is added to the form.

Here's the markup:

<telerik:RadGrid ID="rdTicketGrid" runat="server" Width="70%" AllowAutomaticUpdates="false" AllowAutomaticDeletes="false" AllowAutomaticInserts="false" AllowSorting="false"

OnNeedDataSource="rdTicketGrid_NeedDataSource" AutoGenerateColumns="false" ShowFooter="true"

OnInsertCommand="rdTicketGrid_InsertCommand"

OnUpdateCommand="rdTicketGrid_UpdateCommand"

OnItemCreated="rdTicketGrid_ItemCreated"

OnDeleteCommand="rdTicketGrid_DeleteCommand"

OnItemDataBound="rdTicketGrid_ItemDataBound">

<PagerStyle Mode="NextPrevAndNumeric" />

<MasterTableView DataKeyNames="TicketEntryID" CommandItemDisplay="Top" InsertItemDisplay="Top" InsertItemPageIndexAction="ShowItemOnCurrentPage">

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn"></telerik:GridEditCommandColumn>

<telerik:GridBoundColumn DataField="TicketEntryID" UniqueName="TicketEntryID" Display="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="NumOfTickets" HeaderText="Number of Tickets"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="NumberTicketsInSet" HeaderText="Number of Tickets per Set"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="PriceOfTickets" HeaderText="Price of Tickets" DataFormatString="{0:C}"></telerik:GridBoundColumn>

<telerik:GridCalculatedColumn HeaderText="Total Amount" UniqueName="TotalSetAmount" DataType="System.Double" DataFormatString="{0:C}"

DataFields="NumOfTickets, NumberTicketsInSet, PriceOfTickets" Expression="{0}/{1}*{2}" FooterText="Total: " Aggregate="Sum"

FooterAggregateFormatString="{0:C}">

</telerik:GridCalculatedColumn>

<telerik:GridButtonColumn ConfirmText="Delete this ticket entry?" ConfirmDialogType="RadWindow"

ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" />

</Columns>

<EditFormSettings>

<EditColumn ButtonType="ImageButton"></EditColumn>

</EditFormSettings>

</MasterTableView>

<ClientSettings>

<ClientEvents OnRowDblClick="rowDblClick" />

</ClientSettings>

</telerik:RadGrid>

<telerik:RadInputManager runat="server" ID="rdInputMgr" Enabled="true">

<telerik:NumericTextBoxSetting BehaviorID="TicketEntryIDTBSetting" Type="Number" AllowRounding="false" DecimalDigits="0"></telerik:NumericTextBoxSetting>

<telerik:NumericTextBoxSetting BehaviorID="NumTicketsTBSetting" Type="Number" AllowRounding="false" DecimalDigits="0"></telerik:NumericTextBoxSetting>

<telerik:NumericTextBoxSetting BehaviorID="PriceTicketsTBSetting" Type="Currency" AllowRounding="true" DecimalDigits="0"></telerik:NumericTextBoxSetting>

<telerik:NumericTextBoxSetting BehaviorID="NumberTicketsInSetTBSetting" Type="Number" AllowRounding="true" DecimalDigits="0"></telerik:NumericTextBoxSetting>

</telerik:RadInputManager>

And the code behind data source. The dataset is built and then stored to session. The data will be gathered later on submit.:

DataSet ds = new DataSet();

DataTable dt = new DataTable();

dt.Columns.Add("TicketEntryID");

dt.Columns.Add("NumOfTickets", typeof(int));

dt.Columns.Add("NumberTicketsInSet", typeof(int));

dt.Columns.Add("PriceOfTickets", typeof(double));

ds.Tables.Add(dt);

Session["ticketGridSrc"] = ds;.

Finally the offending method that brakes the grid:

protected void rdTicketGrid_DeleteCommand(object sender, GridCommandEventArgs e)

{

GridEditableItem editableItem = ((GridEditableItem)e.Item);

try

{

int ticketEntryID = int.Parse(((GridDataItem)e.Item).GetDataKeyValue("TicketEntryID").ToString());

//Access the data stored in the session

DataSet currentDataSrc = ((DataSet)Session["ticketGridSrc"]);

if (currentDataSrc != null)

{

//build the select string we need to get the data from the table to delete

String selectStmt = string.Format("TicketEntryID = '{0}'", ticketEntryID);

//Get the row we are deleting from the source.

DataRow[] updateRow = currentDataSrc.Tables[0].Select(selectStmt);

updateRow[0].Delete();

currentDataSrc.AcceptChanges();

}

Session["ticketGridSrc"] = currentDataSrc;

}

catch (Exception ex)

{

//TODO: Error Handling Here

}

Any help on determining why the error occurs would be greatly appreciated.

Thank you,

Grid

Trying to pull data from a cube

I can't find any documentation to show how to write connection strings for pulling from SSAS into Scheduler. I did find this for PivotGrid: http://www.telerik.com/forums/ssas-with-pivotgrid I'm curious if anyone has used the same snippet of code that's listed in the comments:

<AdomdConnectionSettings Cube="Adventure Works" DataBase="Adventure Works DW 2008R2" ConnectionString="Data Source=http://demos.telerik.com/olap/msmdpump.dll;Catalog=Adventure Works DW 2008R2"></AdomdConnectionSettings>

lost alignment after ajax client side bind

Dear All

I have a radgrid need to client side bind. All things work fine except lost alignment after the row initialized from server.

You can see from this demos: http://www.telerik.com/forums/bind-radgrid-client-side-to-a-json-array

if you set the column item alignment to "center" in declaration, you will found only first 4 rows are proper align, which come from server. The rest of them lost alignment.

it also can see from page source code, the rest <td> didn't include the alignment attribute.

Please let me know how to fix it.

Thank you very much.

With best regards

Tommy

Can't find Dynamically Created RadDatePicker in OnLoad

I'm dynamically creating a RadDatePicker in the VB .NET code behind like so...

Dim oCalCell As New HtmlTableCell()

Dim oRadPicker As New Telerik.WebControls.RadDatePicker()

oRadPicker.ID = "cldrStageDate"

oRadPicker.Calendar.ID = "cldrStageDate_calendar"

oRadPicker.Calendar.ClientEvents.OnLoad = "cldrLoaded"

oCalCell.Controls.Add(oRadPicker)

Then on the client side I have the following javascript code:

function cldrLoaded(oCtl) {

var sCtlId = null;

if (typeof(oCtl.get_id) === "function") sCtlId = oCtl.get_id().split('_calendar')[0];

else sCtlId = oCtl.ClientID;

var oCldr = $find(sCtlId);

}

The control is rendered on the page and appears to be working. But inside "cldrLoaded", oCtl doesn't have a function named "get_id" when this function is called, but it does have a "ClientID" set. But the $find(sCtlID) won't find the RadDatePicker.

I have a DatePicker declared in the .aspx page that works as expected:

<telerik:RadDatePicker id="cldrStageDate" runat="server">

<Calendar ID="cldrStageDate_calendar" runat="server">

<ClientEvents OnLoad="cldrLoaded" />

</Calendar>

</telerik:RadDatePicker>

How can I get the proper object get sent to the OnLoad function?

Thanks!

How to programmatically cause RadAjaxManager to update a control.

Hi I have been having this issue in many development requests. Basically I use RadAjaxManager to update controls on a webform, but sometimes certain code is called on the server that should update a control and I need to cause that control to be upated on the screen from code behind. Is there a way to use the RadAjaxManager to achieve this task?

Thanks
