NumericTextBox - Get Masked Text

Hi,
How can I get the masked text from a RadNumericTextBox?
For example...

// RadTextBox

RadNumericTextBox rntb = new RadNumericTextBox();

rntb.NumberFormat.PositivePattern = "n%";

rntb.NumberFormat.DecimalDigits = 0;

rntb.MinValue = 0;

rntb.MaxValue = 100;

rntb.Text = 50; // Displays as "50%"

// How do I get "50%" into a label?

Label lbl = new Label();

lbl.Text = rntb.Text; // Only shows "50". I want to show "50%"

In the above example, how can I get the masked value "50%"?
TextWithLiterals would be great but only applies to RadMaskedTextBox.

Thanks!

RadGrid dynamically Load User Control in InstantiateIn have issues

Here is the link I posted on the asp.net:

http://forums.asp.net/t/1935517.aspx?Load+userControl+first+time+get+called+and+load+properly+Page_Load+then+click+on+the+Sorting+or+pageSize+changed+on+the+RadGrid+that+control+did+not+load

Here is my iTemplate class:
public class iTemplate : ITemplate
{
private string columnName;
Page page;

public iTemplate(string cName, Page page)
{
columnName = cName;
this.page =page;
}

public void InstantiateIn(System.Web.UI.Control container)
{
Control ctrl = new Control();

//System.Web.UI.

//MWStringCrtl mwstringCtrl = (MWStringCrtl)loadMwstringCtrl();
MWStringCrtl mwstringCtrl = (MWStringCrtl)page.LoadControl("~/ServiceModules/Controls/MWStringCrtl.ascx");
mwstringCtrl.Wrapper = new MWStringCrtl.DataWrapper();
mwstringCtrl.ID =container.ClientID+ "_mctrl";
mwstringCtrl.DataBinding += new EventHandler(this.BindData);
mwstringCtrl.Wrapper.ValueOnNewLine = false;
mwstringCtrl.Wrapper.ValueFontSize = 12;
SimpleStringDto blankCell = new SimpleStringDto();
blankCell.Text = "hello";

mwstringCtrl.Wrapper.Data = blankCell;
container.Controls.Add(mwstringCtrl);

GridDataItem container = (GridDataItem)mc.NamingContainer;
mc.Wrapper = (MWStringCrtl.DataWrapper)((RowDataWrapper)container.DataItem).GetType().GetProperty(columnName).GetValue((RowDataWrapper)container.DataItem, null);
}
}

when load the Grid first time, first instantiateIn the User control and bind the data, and lastly Page_Load the dynamically user control.

However, when Sorting or paging, first Instantiateln the User control and Page_Load the dynamically User Control, and last Bind the Data, which in result will have the empty Grid.

anybody can help, it is urgent?

Thanks,T

Refresh RadGrid after insert causes another insert

Duplicate insert problem.

I insert an item and after the insert successfully happens I call:

RadGridOperators.MasterTableView.IsItemInserted = false;

e.Canceled = true;

RadGridOperators.MasterTableView.ClearEditItems();

RadGridOperators.MasterTableView.Rebind();

The edit form does in deed close but if I hit the refresh button on the web browser the insert happens again (EVEN THOUGH THE EDIT FORM IS NOT OPEN). How can I avoid this behavior??

grid in batch edit mode not saving to database if text contains character ; or newline

Entering characters \ / or ; and then clicking "save change" crashes the demo at
batchediting demo
(says page not available)

Saving multiline text also doesnt work. e.Commands in RadGrid1_BatchEditCommand is empty.
Since this looks like a bug in ur control and I need workaround can you plz tell me how can i save updated text manually to database when user presses save changes button?

Also it would be very nice if save button would become enabled only when any changes have been made to the grid. Any easy way I can change that?

ImageManager permission error

Hi All,

I get the attached message when I am trying to upload images or manage images using the imagemanager part of the editor.

I have checked my permission (I also have created the directory at runtime to ensure there isnt an issue) and I still get the error.

I have seen the same error happen on this page

http://demos.telerik.com/aspnet-ajax/editor/examples/dbfilebrowsercontentprovider/defaultcs.aspx when using the image manager part.

The error makes no sense as I can still view and upload files, I just get this annoying message come up

Please help

Thanks

Nathan

Group Header Totals

I know we can perform calculations and add them to a group header:

Private Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)

If TypeOf e.Item Is GridGroupHeaderItem Then

Dim item As GridGroupHeaderItem = CType(e.Item, GridGroupHeaderItem)

Dim groupDataRow As DataRowView = CType(e.Item.DataItem, DataRowView)

item.DataCell.Text = (item.DataCell.Text + "; Avg: ")

item.DataCell.Text = (item.DataCell.Text + (CType(groupDataRow("total"), Decimal) / Integer.Parse(groupDataRow("count").ToString)).ToString)

End If

End Sub

But is there a way to just add the Column aggregate:

<telerik:GridBoundColumn DataField="Subject" FilterControlAltText="Filter Subject column"

HeaderText="Subject" SortExpression="Subject" UniqueName="Subject" ItemStyle-HorizontalAlign="Left"

FooterStyle-HorizontalAlign="Left" FooterText="Tickets " Aggregate="Count">

</telerik:GridBoundColumn>

Thank you in advance.
