Radgridview: Export to Excel question

Hi- I'm having trouble with exporting grid contents to Excel- using winforms radgridview version 2018.1.220.40 in vb.net. (Hopefully this is a stupid question but I've spent an hour looking through documentation and I think I'm missing something.) I found the code snippet below in the documentation, but getting the error

gridViewExport is not defined, and gridviewExportOptions not defined...

I'm assuming that gridViewExport is supposed to be my radgridview object, but when I sub in the name of mine, it says 'export' is not a member of RadGridView...

Can you advise? Thanks very much.

-----------------------------------------

https://docs.telerik.com/devtools/wpf/controls/radgridview/export/export

Private Sub btnExport_Click(sender As Object, e As RoutedEventArgs)
Dim extension As String = "xls"
Dim dialog As New SaveFileDialog() With {
.DefaultExt = extension,
.Filter = String.Format("{1} files (.{0})|.{0}|All files (.)|.", extension, "Excel"),
.FilterIndex = 1
}
If dialog.ShowDialog() = True Then
Using stream As Stream = dialog.OpenFile()
gridViewExport.Export(stream, New GridViewExportOptions() With {
.Format = ExportFormat.Html,
.ShowColumnHeaders = True,
.ShowColumnFooters = True,
.ShowGroupFooters = False
})
End Using
End If
End Sub

Not able to select a row anymore

Hello,

I have some issues with the MultiColumn ComboBox (in the following just CB) in Visual Studio, i'll show you some code steps:

step 1: init CB

With myCB

.ClearTextOnValidation = True

.DataBindings.Clear()

.BestFitColumns()

.ValueMember = "wpno"

.DisplayMember = "wpno"

.DataSource = myDataset.Tables("myTable")

.AutoFilter = True

.AutoCompleteMode = AutoCompleteMode.Append

Dim compositeFilter As New CompositeFilterDescriptor()

Dim selectField1 As New FilterDescriptor("fieldname1", FilterOperator.Contains, "")

Dim selectField2 As New FilterDescriptor("fieldname2", FilterOperator.Contains, "")

Dim selectField3 As New FilterDescriptor("fieldname3", FilterOperator.Contains, "")

compositeFilter.FilterDescriptors.Add(selectField1)

compositeFilter.FilterDescriptors.Add(selectField2)

compositeFilter.FilterDescriptors.Add(selectField3)

compositeFilter.LogicalOperator = FilterLogicalOperator.[Or]

.EditorControl.FilterDescriptors.Clear()

.EditorControl.FilterDescriptors.Add(compositeFilter)

.ValueMember = "wpno"

.DisplayMember = "wpno"

.DataSource = myDataset.Tables("myTable")

End With

step 2: select an entry via the GUI or via

myCB.SelectedIndex = 2

works fine

step 3: open another form to edit some values of the selected entry

Me.Enabled = False

otherForm.Show()

step 4: Edit entry in other form, set a flag and return to first form (containing the CB)

updateEntry(updateField, updateValue)

updComboList = True

firstForm.Enabled = True

Me.Close()

step 5: reload values for the CB

If updComboList Then

updateDataset()

updateCB() 'code from step1

CB.Enabled = True

CB.SelectedIndex = 2 'doesn't work

End If

From now on, no change of selection via SelectedIndex or even via the GUI is possible! The CB is still responsive in terms of colors while hovering cells, but no selection is made when I click anywhere on the drop-down table of the CB. This table doesn't close again either.

Do you have any suggestions? Or is there maybe a bug with this MultiColumn ComboBox?

Thanks heaps.

RadGridView ComboBox

C#, Winforms

I have an XML data source (Main) that I am binding to my gridview. I want one column to be a combobox. I'm using a separate XML file (Options) for the combobox options.

Questions:

1) When I set the data source for the combobox to the Options dataset, the column is blank. I want it to be the value listed in the Main dataset. The result I seek is that when the grid loads, the values from the Main dataset are loaded. The user can then edit the combobox column by selecting from the drop down that is populated from the Options dataset. How can I achieve this?

2) Obviously, I want to save these back edits back to the main dataset. How can I rebind the column to the Main dataset?

Check if context menu is displayed

Hi again!

How can I check if context menu is displayed?

I have a mouse_click event and if the user right clicks off a row (into white space) I display a custom popup. However, when the user right clicks on a row, the context menu pops up and then my menu pops up over top.

What i need to do is to determine whether the user right clicked on a row, or on white space so i can avoid showing my popup if they right clicked on a row.

Thanks.

Button inside of a textbox

Hi,

Is there a way to place a button inside of a textbox?

Here's my scenario:
A user has a textbox to enter words that they wish to search for. After they have searched and they want to clear the results, i want to have a button (a red x button or something) that shows up at the end of the textbox (inside the textbox) allow them to clear the textbox and search results.

I've tried making a RadButtonElement and adding it to the TextBoxElement.Children but the button appears to show up behind the textbox element. I can see and click on the very bottom edge of the textbox and fire the event handler.

    
                    Dim btnElement As New RadButtonElement  
        
                    btnElement.Text = "try this" 
        
                    btnElement.Size = New Drawing.Size(20, 20)  
        
                    Dim textboxElement As RadTextBoxElement = txtSearchFor.TextBoxElement  
        
                    textboxElement.Children.Add(btnElement)  
        
                    AddHandler btnElement.Click, AddressOf btnClearSearh_Click

Thanks

Get formatted cell text (value)

I have gridview with string, date, and numeric columns. Once I set the data source and fill with data, I format each column to a suitable display - eg: short date, 2 decimal places for some, 4 decimals for others, etc. using the column.formatstring.

On a row click I need to get the formatted cell text, not the value and am wondering how I can do this? Eg: the underlying value of a cell is 12345.670000 but is formatted and displayed in the cell as 12,345.67. I could not find a "cell.text" property; and cell.value gives me the raw data.

How can I get the formatted cell text? Thanks, Brendan

use of dialogtype FONT

Hello

I try to use the BrowseEditor in DialogType=FontFialog and I am faced with a few questions:

The value returned is a string ex: "Microsoft Sans Serif; 12pt; style=Bold"

1. How do I convert this string to a font type, taking into account that depending on the culture the size may be shown as 8,5 or 8.5

2. How do I set the initial value of the fonteditor from a fontvariable

4. Selecting "Modern 20, bold, size 8", I get the value: "Modern No. 20; 8,249999pt; style=Bold" (not that I want to use this font but I came across this anomality ,,,)

5. How do I change the initial text "(none)" in a localized text

And While I am on the BrowseEditor, in folderBrowseDialog, I select the intial directory on the .value property and it sets it properly but it is not always "visible" how can I insurevisible on the selected folder

Thanks in advance
