How to localize dynamic filter keywords in WinForms GridGroupingControl?
Localize the dynamic filter keyword
In the dynamic
filter, the keywords of the compare operator are localized properly when
you use ILocalization provider but the keyword Expression Match is not localized because this is added manually by using CreateCompareOperatorList event
in the source. You can localize it by some customized way using WinForms GridGroupingControl.
Solution
This problem can be achieved by handling TableControlCurrentCellShowingDropDown, TableControlCellButtonClicked, and CloseUp events. Refer to the following code examples.
C#
int buttonIndex = 0;
void gridGroupingControl1_TableControlCellButtonClicked(object sender, GridTableControlCellButtonClickedEventArgs e)
{
//Identifies the button index(Compare Operator Button)
buttonIndex = e.Inner.ButtonIndex;
}
void gridGroupingControl1_TableControlCurrentCellShowingDropDown(object sender, GridTableControlCurrentCellShowingDropDownEventArgs e)
{
if (e.TableControl.CurrentCell.Renderer is GridTableFilterBarExtCellRenderer)
{
GridTableFilterBarExtCellRenderer rend = e.TableControl.CurrentCell.Renderer as GridTableFilterBarExtCellRenderer;
var s = rend.ListBoxPart.Items;
if (this.checkBox5.Checked && buttonIndex == 1)
{
rend.DropDownContainer.CloseUp += new PopupClosedEventHandler(DropDownContainer_CloseUp);
rend.ListBoxPart.Items[10] = "expresión de coincidences";
//Specifies your needed localization string
}
}
}
void DropDownContainer_CloseUp(object sender, PopupClosedEventArgs e)
{
if (buttonIndex == 1)
{
if (this.gridGroupingControl1.TableControl.CurrentCell.Renderer is GridTableFilterBarExtCellRenderer)
{
GridTableFilterBarExtCellRenderer rend = this.gridGroupingControl1.TableControl.CurrentCell.Renderer as GridTableFilterBarExtCellRenderer;
if (this.checkBox5.Checked && buttonIndex == 1)
{
if (rend.ListBoxPart.SelectedIndex == 10)
{
object value = "Expression Match...";
//Returns the correct value while closing the dropdown container
rend.ListBoxPart.Items[10] = value;
}
}
}
}
} VB
Private buttonIndex As Integer = 0
Private Sub gridGroupingControl1_TableControlCellButtonClicked(ByVal sender As Object, ByVal e As GridTableControlCellButtonClickedEventArgs)
'Identifies the button index(Compare Operator Button)
buttonIndex = e.Inner.ButtonIndex
End Sub
Private Sub gridGroupingControl1_TableControlCurrentCellShowingDropDown(ByVal sender As Object, ByVal e As GridTableControlCurrentCellShowingDropDownEventArgs)
If TypeOf e.TableControl.CurrentCell.Renderer Is GridTableFilterBarExtCellRenderer Then
Dim rend As GridTableFilterBarExtCellRenderer = TryCast(e.TableControl.CurrentCell.Renderer, GridTableFilterBarExtCellRenderer)
Dim s = rend.ListBoxPart.Items
If Me.checkBox5.Checked AndAlso buttonIndex = 1 Then
AddHandler rend.DropDownContainer.CloseUp, AddressOf DropDownContainer_CloseUp
rend.ListBoxPart.Items(10) = "expresión de coincidencia"
'Specifies your needed localization string
End If
End If
End Sub
Private Sub DropDownContainer_CloseUp(ByVal sender As Object, ByVal e As PopupClosedEventArgs)
If buttonIndex = 1 Then
If TypeOf Me.gridGroupingControl1.TableControl.CurrentCell.Renderer Is GridTableFilterBarExtCellRenderer Then
Dim rend As GridTableFilterBarExtCellRenderer = TryCast(Me.gridGroupingControl1.TableControl.CurrentCell.Renderer, GridTableFilterBarExtCellRenderer)
If Me.checkBox5.Checked AndAlso buttonIndex = 1 Then
If rend.ListBoxPart.SelectedIndex = 10 Then
Dim value As Object = "Expression Match..."
'Returns the correct value while closing the dropdown container
rend.ListBoxPart.Items(10) = value
End If
End If
End If
End If
End SubThe screenshot below illustrates the localization of dynamic filter in GridGroupingControl.
