Question regarding No Wrap for Grid Cells

[Ulrich]

Hi all,

I have some problems regarding No Wrap for Grid Cells and I couldn't find any solution for this in the forum or the tutorials.

I have a grid with a HeaderTemplate and an ItemTemplate and I want to prevent the wrapping for cells content (see attached picture). The grid is filled dynamically, so where and how do I have to insert the NoWrap?

Any help would be appreciated!

Here's my code:

Private Sub Create_Templates(ByRef grdTemplate As RadGrid, ByVal sRegGruppe As String, ByVal nIdGruppe As Integer, ByVal bNurPlatzkosten As Boolean)
        Dim templateColumn As New GridTemplateColumn()
        templateColumn.HeaderText = sRegGruppe
        templateColumn.HeaderTemplate = New MyTemplateHeader(sRegGruppe, nIdGruppe, bNurPlatzkosten)
        templateColumn.ItemTemplate = New MyTemplate(nIdGruppe, bNurPlatzkosten)

        grdTemplate.MasterTableView.Columns.Add(templateColumn)
    End Sub

    Private Class MyTemplateHeader
        Implements ITemplate
        Private sColHeader As String
        Private nIdCol As Integer
        Private bNurPK As Boolean
        Sub New(ByVal sColHeaderBez As String, ByVal nIdGruppe As Integer, ByVal bNurPlatzk As Boolean)
            sColHeader = sColHeaderBez
            nIdCol = nIdGruppe
            bNurPK = bNurPlatzk
        End Sub
        Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements ITemplate.InstantiateIn
            Dim TmpTable As New Table()

            Dim cDS As New TableCell()
            Dim cBU As New TableCell()


            TmpTable.Width = Unit.Percentage(100)
            cReg.Width = Unit.Percentage(100)
            cReg.Text = sColHeader
            cReg.HorizontalAlign = HorizontalAlign.Center
            TmpRow1.Cells.Add(cReg)

            cES.Text = "ES"
            cES.Width = Unit.Percentage(100)

                cDS.Text = "DS"
                cBU.Text = "Buchbar"

                cDS.Width = Unit.Percentage(45)
                cBU.Width = Unit.Percentage(10)

                cDS.HorizontalAlign = HorizontalAlign.Center

Hi Ulrich,

You can do one of the following things:

+ enclose all your template content in a NOBR element. For example, insert the opening and closing tags as literal controls.
+ enclose (where needed) the table cell content in a NOBR element or inside an additional HTML element with disabled text wrapping, for example: <div style="white-space:nowrap">.........</div>

The second option is better.

Thank you for your reply.

I saw that link you posted before, but I can't seem to apply that solution. The ColumnCreated event is not being called.
I only use Literal controls in the Templates.

My grid runs completely dynamically. It is created dynamically on the webform and the datasource is also set dynamically.

Hello Ulrich,

ColumnCreated is fired for autogenerated columns only. In all other cases you can set the DataFormatString property manually when adding the column.

The help article was supposed to give a more broader insight on the matter. You don't have to apply the workaround exactly as specified there - the suggestions from my previous message are recommended. Do you have any troubles implementing them?

Thanks again. Please bear with me because I'm fairly new to ASP.Net.

I'm not sure how to implement your suggestions.

Since we only use templates, I have some problems understanding what part I have to enclose in a NOBR element in order to prevent the wrapping. Also, I'm not sure where I can set the DataFormatString property.

Hi Ulrich,

>> "what part I have to enclose in a NOBR element"

Do it with for the content of each table cell, that needs disabled text wrapping, i.e. modify the way you set the cell's Text property. In case you have cells, which you add controls to (cell.Controls.Add(....)), the do this:

cell.Controls.Add(new LiteralControl("<nobr>"));
cell.Controls.Add( your controls here );
cell.Controls.Add(new LiteralControl("</nobr>"));



Kind regards,

Thanks a lot, that worked.
