is there a GridViewDecimalColumn equivalent form RadTextBox or RadMaskedEdit?

Hi,

I would like to have a textbox control (or maskededit) which mimic GridViewDecimalColumn default editor. That is a control that accepts only decimal numbers, that could have a minvalue and a maxvalue, that do not has the need for a mask. Exactly as the GridViewDecimalColumn editor.

thank you

Child Grid Width

Hello,

I'm trying to set the grid width of the child table but cannot find the property/method to do so?
I've set the outer grid width fine I think.

Dim OrderLinesTemplate As New GridViewTemplate

OrderLinesTemplate.AllowAddNewRow = False

OrderLinesTemplate.DataSource = myOrderLines

OrderLinesTemplate.Columns(0).Width = 100

OrderLinesTemplate.Columns(1).Width = 200

OrderLinesTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.None

Me.RadGridView1.MasterTemplate.Templates.Add(OrderLinesTemplate)

and then try to set the inner (child) grid on the on gridview formatting event:-

Private Sub RadGridView1_ViewCellFormatting(sender As Object, e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles RadGridView1.ViewCellFormatting

If TypeOf e.CellElement Is GridDetailViewCellElement Then

e.CellElement.BorderWidth = 10

e.CellElement.AutoSize = False

e.CellElement.Size = New System.Drawing.Size(350, 150)

End If

End Sub

Attached is the screen print of the output and what I'm trying to achieve for clarity.

Many thanks

Terry

Referring to columns in a typesafe manner

I've run into a number of times now where I find myself having to refer to a column by its name, which rubs me the wrong way; for example, the following snippet to run through and check whether or not all of the selected cells are in the same column:

allDataCells = true;

foreach (GridViewCellInfo cell in commandGridView.SelectedCells)

{

if (cell.ColumnInfo.Name != "columnData")

{

allDataCells = false;

break;

}

It bugs me that I'm using the text name rather than the actual column variable. I know, in my example scenario, that the column variable is actually "gridViewTextBoxColumn8" (which could be a better name, I know).

Other than comparing on the name variables, which is a little better:

gridViewTextBoxColumn8.Name == cell.ColumnInfo.Name

...is there a "good" way to do this? When given a GridViewCellInfo item, what's the type-safe and typo-safe way to compare the column?

Thanks!
Dave

Newbie Asks, "How do I select a theme for a control?"

I am just starting to work with the window form controls. I am using the Rad Page View control (Backstage View). Working with the designer, I only have these options under ThemeName (Reset, ControlDefault).

How do I enable the other prepackaged themes? I think I can use one of the pre-packaged themes for my needs, I just can't find the switch.

Thanks for the help.

ExportToExcelML Freeze Column

Hello,

I am exporting the contents of a RadGridView to an Excel file and would like to freeze (or pin) the grid header and first column in the Excel file. I am aware that RAD ASP.NET controls can do this, but am unaware of how this can be accomplished with WinForms.

I have attempted setting the the "IsPinned" value for these rows/columns to true, but this does not affect the Excel file. Nor are there any options or events on either the grid or the ExportToExcelML object.

Please let me know as soon as possible, my deadline is drawing very near.

ExportToExcelML.RunExport exception

Hello,
I need to export radGridView into xls file throught ExportToExcelML. For these puprose I use this code

    
            SaveFileDialog saveDialog = new SaveFileDialog(); 
        
            saveDialog.DefaultExt = "xls"; 
        
            saveDialog.Filter = "Excel (*.xls)|*.xls"; 
        
            saveDialog.OverwritePrompt = true; 
        
            saveDialog.CreatePrompt = true; 
        
            if (saveDialog.ShowDialog() == DialogResult.OK) 
        
            { 
        
               if (string.IsNullOrEmpty(saveDialog.FileName)) 
        
               { 
        
                   MessageBox.Show("Please enter a file name."); 
        
                   return; 
        
               } 
        
               ExportToExcelML export = new ExportToExcelML(); 
        
               export.HiddenColumnOption = ExportToExcelML.HiddenOption.ExportAsHidden; 
        
               export.HiddenRowOption = ExportToExcelML.HiddenOption.ExportAsHidden; 
        
               export.RunExport(bestellungRadGridView, saveDialog.FileName, ExportToExcelML.ExcelMaxRows._65536, true);                 
        
            }

But on the last line of code (export.RunExport(....)) I get the exception "Worksheet collection cannot be empty." and the inner exception is empty.
Is there some problem in my code or it is some general problem of ExportToExcelML class?

Thank you for your response
Petr

ConditionalFormattingObject with CheckBox in row

Hi,

I'm having a little problem, I have a RadGridView where the startup form I do:




ConditionalFormattingObject c2 = new ConditionalFormattingObject("Test_A", ConditionTypes.Equal, "true", String.Empty, true);
            c2.CellForeColor =
            c2.RowForeColor = Color.Blue;
            gdvAuditoria2.Columns[NomesColunasGridAuditoria.Validar].ConditionalFormattingObjectList.Add(c2);
            gdvAuditoria2.Columns[NomesColunasGridAuditoria.Rejeitar].ConditionalFormattingObjectList.Add(c2);
 
            ConditionalFormattingObject c3 = new ConditionalFormattingObject("Test_B", ConditionTypes.Equal, String.Empty, String.Empty, true);
            c3.CellForeColor =
            c3.RowForeColor = Color.Black;
            gdvAuditoria2.Columns[NomesColunasGridAuditoria.CodAuditoria].ConditionalFormattingObjectList.Add(c3);
 
            ConditionalFormattingObject c1 = new ConditionalFormattingObject("Test_C", ConditionTypes.Equal, "true", String.Empty, true);
            c1.CellForeColor =
            c1.RowForeColor = Color.Red;
            gdvAuditoria2.Columns[NomesColunasGridAuditoria.Substituido].ConditionalFormattingObjectList.Add(c1);

More formatting that is being changed only when changing line.

How can I do to change a value after a row with checkbox that formatting is applied?

Updating appointments with TableAdapters

Hello,

I have a form that uses databinding using Dataset/TableAdapter for the Appointments. I have one table - Appointments. If I were to use a button to update the dataset to persist the data, will I still need to hit the "Ok" button before I hit the Update button? I am using the Timeline view and it displays the appointments from table correctly. However, after dragging to new start and end date, I have to select "All day event" then hit Ok and then the update button before my changes are saved.

What am I doing wrong?

Thanks.
