UseSystemPasswordChar property for RadTextBox?

Hello,

I am wondering if I can use the UseSystemPasswordChar property with the Radtextbox. It works with the traditional texbox but does not seem to work with the radtexbox.

For the moment, I am using an alternative solution which is:

radTextBoxNewPass.PasswordChar = '*';

Thank you,
LB

Hierarchical mode in RadgridView

Hi ,

I have a RadGridView that shows some data in Hierarchical mode.

I have a problem in this scenario:

First. I expand more data in GridView(so, it shows child of node and child of child and ......).
Second. I use RadGridView,Rows.Add() function to add 1 row. The row successfully added, but the added row go bottom of gridview and the vertical Scroll lost trust value.

So, I should "up down" and "Up down" the vertical scroll to get correct value.

any suggestion please?!

How can i check in which column the selected cell is?

Situation
In this situation i have 3 resources/columns in the scheduler.
Every resource/column has his own available times.
I have disabled the cells when the time is not available.
I want to drag and drop a appointment in an cell.
It has to check if that cell/timeslot is available.

Problem
I don't know how to check in which column the drag and drop cell is. So it checks all resources/Columns.
If in one resource/column a cell/time is disabled then it gives back that it is not available.

How can i check in which column the selected cell is?

private void radScheduler1_DragDrop(object sender, DragEventArgs e)

{

DragObject dragObject = e.Data.GetData(typeof(DragObject)) as DragObject;

Point point = this.radScheduler1.PointToClient(new Point(e.X, e.Y));

SchedulerDayViewGroupedByResourceElement groupedDayViewElement = this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewGroupedByResourceElement;

SchedulerCellElement schedulerCell = SchedulerUIHelper.GetCellAtPoint(point, groupedDayViewElement.GetDayViewElements());

SchedulerCellElement schedulerCell2 = SchedulerUIHelper.GetCells(this.radScheduler1).Where(x => x.Date >= schedulerCell.Date && x.Date <= SchedulerCell.Date.AddMinutes(((double)dragObject.Values[Enums.AppointmentFields.Duration])-1)

&& x.Enabled == false).FirstOrDefault();

Fix columns to left

Hello,
I have tried to customing a gridview row with html view like it is recommended in a few posts.
The result is not which i want, I want something like this:

[--colLeft--][----------------------col-----------------------]
[------------------------------------col-------------------------]
[--colLeft--][--colLeft--][--colLeft--][------col--------]

When I resize the gridviewI want to colLeft stay at left like:

[--colLeft--][----------------------------------------col------------------------------------]
[-----------------------------------------col---------------------------------------------------]
[--colLeft--][--colLeft--][--colLeft--][-----------------col----------------------------]

To make that I have used this C# code:

// Row struct in html view

this.htmlView = new HtmlViewDefinition();

this.htmlView.RowTemplate.Rows.Add(new RowDefinition());

this.htmlView.RowTemplate.Rows[0].Cells.Add(new CellDefinition("IsLocked", 0, 1, 1));

this.htmlView.RowTemplate.Rows[0].Cells.Add(new CellDefinition("name", 0, 3, 1));

this.htmlView.RowTemplate.Rows[1].Cells.Add(new CellDefinition("details", 0, 4, 1));

this.htmlView.RowTemplate.Rows[2].Cells.Add(new CellDefinition("preview", 0, 1, 1));

this.htmlView.RowTemplate.Rows[2].Cells.Add(new CellDefinition("insert", 0, 1, 1));

this.htmlView.RowTemplate.Rows[2].Cells.Add(new CellDefinition("remove", 0, 1, 1));

this.htmlView.RowTemplate.Rows[2].Cells.Add(new CellDefinition("link", 0, 1, 1));

It works but when I'm resizing the gridview, cells are automaticly re-arranged (size and location) and centered so columns I want to fix on the left side (colLeft) moving. Like that:

[-------colLeft------][----------------------------------------col----------------------------------------------------]
[-----------------------------------------col----------------------------------------------------------------------------]
[-------colLeft------][-------colLeft------][------colLeft------][-----------------col----------------------------]

My question is How can I fix columns size to X pixels and location to left to make what I want?

Thanks

Add multiple rows based on field validation

Hi,

I want to add (create and add to my datasource) multiple rows to my grid based on validating a field in the 'add new row' row.
At present, when I do this (as described below) it leaves me with the row being added. I would like to cancel the added row. In doing this I have been wondering if I am going about it all incorrectly, however:

I am unsure if I should perform some other function that captures the Add New Row functionality, if I should be doing what I'm doing (validating on CellValidating and adding the new rows) or using CellEndEdit or some other function to perform the load and cancelling the original edit.

In the grid (ProductCode, Operation, Quantity, Hours, and some resultant fields), I am trying to allow the user to enter in a specific sub-product code - to enter in one line, or to enter in a parent product code which will pre-populate a bunch of rows (for all the children meeting the criteria).

It currently is working as I want, barring the cancelEdit usage after adding in bulk. I'm not sure how to accomplish this (or do it better). Any advice would be really appreciated!

Here is basically what I currently have:

Private Sub rgvProducts_CellValidating(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellValidatingEventArgs) Handles rgvProducts.CellValidating

Dim col As GridViewDataColumn = e.Column

Dim validateMessage As String = ""

lblMsg.Text = ""

If quitValidating Then

Return

End If

If e.Row IsNot Nothing Then

'if new row and field entered is "ProductCode"

If e.Row.GetType Is GetType(GridViewNewRowInfo) AndAlso col.FieldName = "ProductCode" Then

If String.IsNullOrWhiteSpace(e.Value) Then

'show validation message: cannot be blank

Return

End If

Dim coreProducts As DataTable

Dim lp As LabourProduct

Dim resultsMessage As String = ""

'Check if ProductCode value is valid against CoreProduct mapping

If ApplicationFunctions.fieldValidate("CoreProductCode", e.Value) Then

coreProducts = Labour.retrieveCoreProductRows("", e.Value, cl.Operation) 'retrieve set of CoreProduct rows filtered by Operation

If coreProducts.Rows.Count = 0 Then

'show validation message: No CoreProduct items found

Return

ElseIf coreProducts.Rows.Count = 1 Then 'if single row returned, allow editing in-line

rgvProducts.CurrentRow.Cells("ProductCode").Value = coreProducts.Rows(0)("CoreProductCode")

rgvProducts.CurrentRow.Cells("Operation").Value = coreProducts.Rows(0)("Operation")

rgvProducts.CurrentRow.Cells("ActualQuantity").Value = coreProducts.Rows(0)("StandardQuantity")

rgvProducts.CurrentRow.Cells("StandardQuantity").Value = coreProducts.Rows(0)("StandardQuantity")

rgvProducts.CurrentRow.Cells("StandardHours").Value = coreProducts.Rows(0)("StandardHours")

rgvProducts.CurrentRow.Cells("EarnedHours").Value = coreProducts.Rows(0)("StandardHours")

rgvProducts.CurrentRow.Cells("Description").Value = coreProducts.Rows(0)("ProductDescription")

Return

Else

resultsMessage = ProcessCoreProductDataTable(coreProducts) 'This adds multiple rows to grid and saves the objects

If Not resultsMessage = "Success" Then

'show validation message: Error saving

Return

Else 'Here trying to rebind the data source and cancel the edit

ApplicationFunctions.showMsg(lblMsg, resultsMessage, ApplicationFunctions.AlertModes.Positive)

rgvProducts.DataSource = ""

rgvProducts.DataSource = cl.LabourProductList

rgvProducts.CancelEdit()

End If

Else 'if not matched against the CoreProduct, then trying to match against Product parent

coreProducts = Labour.retrieveCoreProductRows(e.Value, "", cl.Operation)

If coreProducts.Rows.Count > 0 Then 'if rows returned then add them

resultsMessage = ProcessCoreProductDataTable(coreProducts)

If Not resultsMessage = "Success" Then

ApplicationFunctions.showMsg(lblMsg, resultsMessage, ApplicationFunctions.AlertModes.Negative)

e.Row.ErrorText = resultsMessage

e.Cancel = True

Return

Else

ApplicationFunctions.showMsg(lblMsg, resultsMessage, ApplicationFunctions.AlertModes.Positive)

rgvProducts.DataSource = ""

rgvProducts.DataSource = cl.LabourProductList

rgvProducts.CancelEdit()

End If

'else show validation message: product code entered invalid

End If

ElseIf (e.Row.GetType Is GetType(GridViewDataRowInfo) Or e.Row.GetType Is GetType(GridViewNewRowInfo)) And Not col Is Nothing Then 'only inline editing for any already entered rows

validateMessage = validate(col.FieldName, e.Value)

If validateMessage <> String.Empty Then ApplicationFunctions.showMsg(lblMsg, validateMessage, ApplicationFunctions.AlertModes.Negative)

End If

End Sub

'add items in bulk and save

Private Function ProcessCoreProductDataTable(ByRef coreProducts As DataTable) As String

Dim saveMessage As String = ""

Dim lp As LabourProduct

For Each cp As DataRow In coreProducts.Rows

lp = New LabourProduct()

lp.LabourID = cl.LabourID

lp.ProductCode = cp("CoreProductCode")

lp.CoreBoxNumber = lp.ProductCode.Substring(lp.ProductCode.LastIndexOf("_C"))

lp.Operation = cp("Operation")

lp.ActualQuantity = cp("StandardQuantity")

lp.StandardQuantity = cp("StandardQuantity")

lp.StandardHours = cp("StandardHours")

lp.EarnedHours = cp("StandardHours")

lp.Description = cp("ProductDescription")

If Not lp.save(saveMessage) Then

Return saveMessage

Else

cl.LabourProductList.Add(lp)

End If

Next

Return saveMessage

End Function
