Good Day,

I've got a grid with a whole bunch of columns which I'm exporting to HTML,CSV and Excel with no problems at all, but when I export the grid to PDF my column data overlaps as shown in the below image link.

http://www.mediafire.com/?3crbrazsocq9n5x

Here are the settings below I'm using for my export and I'm using Adobe Reader 9 to view the PDF. I'm using the Telerik WinForms Q3 2010 Control Set - v2010.3.10.1109

Private Sub ExportToPDF(ByVal sFileName As String, ByVal oRadGridView As RadGridView, ByRef bOpenExportFile As Boolean)

Dim exporter As Export.ExportToPDF = New Export.ExportToPDF(oRadGridView)

exporter.HiddenColumnOption = Telerik.WinControls.UI.Export.HiddenOption.DoNotExport

exporter.PdfExportSettings.PageHeight = 210

exporter.PdfExportSettings.PageWidth = 297

exporter.Scale = 1

exporter.FitToPageWidth = True

exporter.ExportVisualSettings = True

exporter.RunExport(sFileName)

bOpenExportFile = AskToOpen(oRadGridView)

End Sub

Thank You

Checkbox Column not showing Checkbox

I have a gridview with a datasource bound to a binding list of custom objects. I have added a checkbox column with the following code:

GridViewCheckBoxColumn checkBoxColumn = new GridViewCheckBoxColumn();

checkBoxColumn.DataType = typeof(int);

checkBoxColumn.UniqueName = "DiscontinuedColumn";

checkBoxColumn.FieldName = "Discontinued";

checkBoxColumn.HeaderText = "Discontinued";

conversionTypesGridView.Columns.Add(checkBoxColumn);

The column shows up in the gridview however there are no checkbox's in the column.
AutoGenerateColumns is false and AutoSizeColumns is set to AutoFill.
I am using version 2009.3.9.1203.

Thanks,

GridView

[Solved] IDataErrorInfo and Validation

We are binding our grids to a BindingList<T> where T is a business object that implements IDataErrorInfo.

How do we "hook up" data validation in the GridView in this case?

When we had it bound to the Microsoft DataGridView we did not have to do anything. The error icons automatically appeared in the cell using the text defined using the IDataErrorInfo properties. But this does not appear to work with the GridView?

I read through what I could find on validation in the documentation and it appeared to require writing code in the Validating events. Is this still required when the binding source uses IDataErrorInfo?

Thanks!

[Solved] Sizing GridViewMultiComboBoxColumn in gridview

I have added a GridViewMultiComboBoxColumn column from code behind into a gridview. Everthng works well but the drop down is very narrow and does not display the entire contents in each row. What is the best way to size this control so that all values are displayed in its entirety. Some of the things I have tried did not work.

cboCategory.FieldName =

"Category"

'cboCategory.HeaderText = "Category"

cboCategory.DataSource = objDT

cboCategory.ValueMember =

"Category"

cboCategory.DisplayMember =

"Category"

'cboCategory.Width = 0.2 * Me.RadQueuedFiles.Width

cboCategory.AutoSizeMode = BestFitColumnMode.DisplayedDataCells

'cboCategory.BestFit()

[Solved] Problem with group descriptor

I have created an unbound grid as follows

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("GUID"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("P_ID"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("T_ID"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("Project_Name"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("T Information"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("File_Path"))

RadQueuedFiles.Columns.Add(New GridViewTextBoxColumn("File Name"))

RadQueuedFiles.MasterTemplate.AllowAddNewRow = False

RadQueuedFiles.AutoSizeRows = True

RadQueuedFiles.Columns(0).IsVisible = False

RadQueuedFiles.Columns(1).IsVisible = False

RadQueuedFiles.Columns(2).IsVisible = False

RadQueuedFiles.Columns(3).Width = 0.15 * Me.RadQueuedFiles.Width

RadQueuedFiles.Columns(4).DisableHTMLRendering = False

RadQueuedFiles.Columns(4).Width = 0.55 * Me.RadQueuedFiles.Width

RadQueuedFiles.Columns(5).IsVisible = False

RadQueuedFiles.Columns(6).Width = 0.35 * Me.RadQueuedFiles.Width

RadQueuedFiles.AllowEditRow = False

RadQueuedFiles.AllowAddNewRow = False

Dim descriptor As New GroupDescriptor()

descriptor.GroupNames.Add("Project_Name", System.ComponentModel.ListSortDirection.Ascending)

Me.RadQueuedFiles.GroupDescriptors.Add(descriptor)

When I run the program and add rows programatically, it groups by value in GUID column and not the project name... sample add is below

RadQueuedFiles.Rows.Add(Guid.NewGuid, cboProjectName.SelectedValue, RadT.CurrentRow.Cells(0).Value, cboProjectName.Text, strProjectIdentifier, file, file.Split(

"\")(file.Split("\").Count - 1))

What am I missing?

[Solved] Any way to show "Please Select" in databound dropdownlist

I have a WinForms dropdown list in DropDownList Sytle that is bound to a datatable. I've read several articles in the forums, but found nothing to either let me set the selection to blank after binding, or insert a "Please Select" selection either before or after binding.

I've tried setting the text property and the Null Text property and these don't work either.

Any suggestions?
