Image Manager Errors

I think I'm missing something obvious, but I surrender. I have an editor with the image manager tool enabled. Below is my code behind code setting it all up, you can see that I create the directory if it is not there. The image uploads successfully and is in the right directory. However I am getting these three errors

After an upload – You are trying to navigate to a non-existing folder or you do not have proper permissions…
After I try the Image Edit - ImageEditor_Common_MessageCannotWriteToFolder
After I try to Delete – The selected file could not be deleted because the application did not have enough permissions.

Any hints would be greatly appreciated.

'set imagemanager paths

Dim sImage As String = SSG.BYOC.Shared.Resource.GetClassroomSaveToFilePath(AppConfig.ClassroomFileUploadRoot, ClassID)

Dim sImagePath As String = Server.MapPath(sImage)

Dim imagePath As String() = New String() {sImage}

' Dim imageFilters As String() = New String() {"gif", "jpg", "jpeg", "png"}

If Directory.Exists(sImagePath) = False Then

Directory.CreateDirectory(sImagePath)

End If

'ctlDescription.ImageManager.SearchPatterns = imageFilters

ctlDescription.ImageManager.ViewPaths = imagePath

ctlDescription.ImageManager.UploadPaths = imagePath

ctlDescription.ImageManager.DeletePaths = imagePath

Dynamic grouping on columns with null values

when creating groups dynamically to a grid with template columns, the application is throwing an unhandled exception error if the groupbe by column holds null values. If the underlying data source is modified to replace null values with "" then the grid functions fine. The way its to behave the columns to be grouped by can change so I need a way to handle nulls in the application code. Does anyone have a solution for this?

Dim ex As New GridGroupByExpression()
For Each dRow As DataRow In objDS.Tables(2).Rows
Dim field1 As New GridGroupByField()
field1.FieldName = dRow("Column_Name")
field1.HeaderText = dRow("display_name")
field1.SortOrder = dRow("Sort_Order")
ex.GroupByFields.Add(field1)
ex.SelectFields.Add(field1)

Next

EditGrid.MasterTableView.GroupByExpressions.Add(ex)

Get ID of inserted record.

I've searched the forums with no luck.

What I need to do is send an email with the ID of the newly inserted items ID that is generated from SQL(isIdentity)

I was assuming that I could get this info from RadGrid1_ItemInserted but no luck.

Dim editformItem As GridEditFormInsertItem = DirectCast(e.Item, GridEditFormInsertItem)
Dim test As String = editformItem.Item("Task_Id").Text

-DataKeyNames="Task_Id"

I need the id of the inserted item.

Can someone please help.

Thank you

plotting x y in a grid

Not sure whether to use a RadGrid or some other solution here...

I have a database table with x, y coordinate, and a content field.

I want to plot the content in a grid according to the x,y and knowing the size of the total grid, ie 12x6, or 20x10, etc...

Some cells may be empty (no row in the table).

Suggestions?

Losing Grid column metadata when batch editing rad grid that is statically declared with dynamically defined columns

Hi

I'm having problems with the grid losing the dynamic column metadata when using the batch edit "save changes" and cancel changes" buttons. See the attached pictures. The grid is declared in the ASPX page and the columns are assigned in the page_load event only on the first page load.

Here is the grid declaration:

<telerik:RadGrid

ID="radGridGrades"

runat="server"

AllowPaging="false"

Width="100%"

enableEmbeddedSkins="false"

Skin="CorpsNETBootstrap"

AllowSorting="true"

ClientSettings-Selecting-AllowRowSelect="true"

AllowMultiRowSelection="true"

ClientSettings-AllowKeyboardNavigation="true"

ItemStyle-HorizontalAlign="Center"

HeaderStyle-HorizontalAlign="Center"

AlternatingItemStyle-HorizontalAlign="Center"

AllowMultiRowEdit="true"

OnBatchEditCommand="radGridGrades_BatchEditCommand"

OnNeedDataSource="radGridGrades_NeedDataSource"

OnItemDataBound="radGridGrades_ItemDataBound">

<MasterTableView

AutoGenerateColumns="False"

DataKeyNames="ID"

Width="100%"

CommandItemDisplay="Top"

CommandItemStyle-Height="15px"

CommandItemSettings-ShowCancelChangesButton="true"

CommandItemSettings-ShowAddNewRecordButton="false"

PageSize="10"

EnableNoRecordsTemplate="true"

EditMode="Batch"

InsertItemPageIndexAction="ShowItemOnCurrentPage">

<Columns>

</Columns>

<EditFormSettings>

<PopUpSettings ScrollBars="None" />

</EditFormSettings>

<NoRecordsTemplate>

<div align="center" style="color:darkorange">---------- No Records to Display -----------</div>

</NoRecordsTemplate>

</MasterTableView>

<ClientSettings>

</ClientSettings>

</telerik:RadGrid>

And here is the code-behind for the page:

public partial class GradesByClass : CorpsNET.BasePage

{

CorpsNETServer.ScheduledClass _scheduledClass;

CorpsNETServer.Lookup _academicSchedule;

CorpsNETServer.AcademicAssignment _academicAssignment;

protected void Page_Load(object sender, EventArgs e)

{

base.Page_Load(sender, e);

if (Request.QueryString["ScheduledClassID"] != null)

{

_scheduledClass = ScheduledClassService.GetByID(Int32.Parse(Request.QueryString["ScheduledClassID"]));

}

if (!Page.IsPostBack)

{

if (((UserProfile)Session["_userProfile"]).IsAuthorized("Grades - Edit") == true)

{

Master.SetLocation("GradesByClass.aspx", "Grade Entry for: <b>" + _scheduledClass.SubjectName + "</b>", true);

}

else

{

throw new CorpsNETServer.CorpsNETAuthException("Grades - Edit");

}

//rdpRosterDate.SelectedDate = DateTime.Now;

lblClassPeriod.Text = _scheduledClass.ClassPeriodName;

lblClassroom.Text = _scheduledClass.ClassroomName;

lblClassSchedule.Text = _scheduledClass.ClassroomScheduleName;

lblSubject.Text = _scheduledClass.SubjectName;

lblTeacher.Text = _scheduledClass.TeacherName;

lblTrimester.Text = _scheduledClass.TrimesterName;

LoadGridStructure();

}

public void LoadGridStructure()

{

radGridGrades.Columns.Add(new GridBoundColumn() { ReadOnly=true, UniqueName = "Corpsmember", DataField = "EmployeeName", HeaderText = "Corpsmember", SortExpression = "EmployeeName" });

radGridGrades.Columns.Add(new GridBoundColumn() { ReadOnly = true, UniqueName = "AcademicScheduleName", DataField = "AcademicScheduleName", HeaderText = "Academic Schedule", SortExpression = "AcademicScheduleName" });

radGridGrades.Columns.Add(new GridBoundColumn() { ReadOnly = true, UniqueName = "CurrentStatusName", DataField = "CurrentStatusName", HeaderText = "Current Status", SortExpression = "CurrentStatusName" });

List<AcademicAssignment> _academicAssignemnts = AcademicAssignmentService.GetForScheduledClass(_scheduledClass.ID);

for (int i = 0; i < _academicAssignemnts.Count; i++)

{

radGridGrades.Columns.Add(new GridBoundColumn() { UniqueName = _academicAssignemnts[i].ID.ToString(), HeaderText = "Assignment: <a href='#' class='RadGrid_CorpsNETBootstrap_a' onclick =openEditAcademicAssignmentWindow(" + _academicAssignemnts[i].ID + "); return false;>" + _academicAssignemnts[i].Name + "</a> Due Date: <b>" + _academicAssignemnts[i].DueDateString + "</b>" });

}

public void LoadStudents()

{

radGridGrades.DataSource = EmployeeService.GetForScheduledClass(_scheduledClass.ID);

}

protected void radGridGrades_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridEditableItem form = (GridEditableItem)e.Item;

int employeeid = Int32.Parse(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ID"].ToString());

//goto through all the assignments and load any existing grades for that assignment

List<AcademicAssignment> _academicAssignments = AcademicAssignmentService.GetForScheduledClass(_scheduledClass.ID);

for (int i = 0; i < _academicAssignments.Count; i++)

{

//radGridGrades.Columns.Add(new GridBoundColumn() { UniqueName = _academicAssignemnts[i].ID.ToString(), HeaderText = "Assignment: <b>" + _academicAssignemnts[i].Name + "</b> Due Date: <b>" + _academicAssignemnts[i].DueDateString + "</b>" });

//get the grade for this assignment and Employee

Grade _grade = GradeService.GetForAcademicAssignment(employeeid, _academicAssignments[i].ID);

if (_grade != null)

{

if (_academicAssignments[i].LetterGrade == true)

form[_academicAssignments[i].ID.ToString()].Text = _grade.LetterGrade;

else

form[_academicAssignments[i].ID.ToString()].Text = _grade.Points.ToString();

}

else

form[_academicAssignments[i].ID.ToString()].Text = string.Empty;

}

protected void radGridGrades_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

LoadStudents();

}

protected void radGridGrades_BatchEditCommand(object sender, GridBatchEditingEventArgs e)

{

//todo

}

On the first page load everything works fine. (see pic 1) I want to edit only the values in a single column. I'm aware that I have not yet implemented the save code. the problem is that the first columns lose their definitions after postback by either the 'cancel changes' or 'save changes' batch edit buttons. CAn you point me in the right direction? Thanks.
