UXGridView - Silverlight - Column Footers Disappear until column header clicked

irishbuddha22 — Tue, 21 Oct 2014 13:29:07 GMT

Scenario: UXGridView tied to a PagedCollectionView

When the PagedCollectionView is tied to an underlying <ObservableCollection>, and the collection is cleared and re-loaded, the UXGridView entirely loses the column footers and they become blank.

Column Footers are perfect on initial entry, no issues there
Clicking on a column header to sort the UXGridView causes the footers to re-appear

Is there a trick to not losing the footers in this situation, or a setting that I'm missing? I've tried doing a PagedCollectionView.Refresh() to no avail, and can't seem to have the footers just stay in place and get updated like they do on initial display.

UXGridView - Remove / Collapse / Hide the grid footer

irishbuddha22 — Fri, 27 Sep 2013 12:49:40 GMT

Silverlight UXGridView

Not seeing a straightforward way to do it, but has anyone found a way to hide/remove the Grid footer on a UXGridView. (The footer bar that also contains the refresh button at the bottom right by default).

Boss wants to end the grid after the last data row, no footer at all for the entire grid.

Problem with hyperlink inside UXGridView

gzhebrunov@googlemail.com — Mon, 19 Nov 2012 11:41:22 GMT

Hello,

I have problem with UXGridView. I need to show HyperLink (with absolute Uri) inside grid. I tried following solutions:

1. <Intersoft:UXGridViewHyperlinkColumn Header="PROVIDER" Width="260" Binding="{Binding Path=Name}" NavigateUriBinding="{Binding Path=Url}"></Intersoft:UXGridViewHyperlinkColumn>

Not working, showing error about Absolute to Relative Uri convertion.

2. Intersoft:UXGridViewTemplateColumn and Intersoft:HyperLink inside. Not sure how to setup text of hyperlink in this case.

3. Intersoft:UXGridViewTemplateColumn and typical HyperLinkButton control. Showing without problems, but can not click on it (I think because grid not allowing events or something like that).

I think solution should be trivial. Please help!

Problem with button inside UxGridViewColumn

jabas06 — Thu, 23 Aug 2012 21:46:13 GMT

Hi,

I customize a cell template in an UXGridViewColumn, and put inside of DataTemplate a button.

I need to perform an action on button's click event, but UXGridView eats the event. How can I do that?

I'm using ClientUI 7 with last hotfixes.

operation speed is very slow if we have a Page with an UXGridView and UXTreeView

gavin — Tue, 15 Nov 2011 04:11:26 GMT

Hi,

Question one:
We are using different ClientUI5 Controls on one Page.In our example we have a Page with an UXGridView(page size is 20,has 25 columns), UXTreeView(has about 1000 items) and UXTabControl.The issue is that operation speed is very slow on this page, and it is taking a lot of time to select one item or to edit one item.This is a big problem about performance.
1> It seems if the page only has the UXGridView or the UXTreeView, the operation speed is be fine.
2> It seems if we reduce the number of UXTreeView's Items, the operation speed can be increased( performance improvement).
3> It seems if we reduce the number of UXGridView's Columns, the operation speed can be increased( performance improvement).
So Is there a limit to how many objects you can export on one page?Please give me some advise.

gavin — Sat, 05 Nov 2011 01:17:09 GMT

Hi,

UXGridView Server Side Validation

mg@hsig.ch — Wed, 02 Nov 2011 05:19:23 GMT

I use Client UI MVVM Data Application with RIA Services. I have added Atributes on Metadata Class, eg. DataAnnotations.RequiredAttribute

[Required(ErrorMessage = "Eingabe erforderlich!")]
[StringLength(250, ErrorMessage = "Es sind max. 250 Zeichen erlaubt!")]
public string FQDN { get; set; }

When the Cell is empty, I get the Errormessage in UXGridView Footer and the row has a red background color. Please have a look at attached picture (1). This works fine.

Now, I have to validate also on server side. In my case, the FQDN must be unique. So I have writ following method:

public bool IsComputerFQDNRegistered(string fqdn)
{
    return _qmsEntities.Computer.Where(c => c.FQDN == fqdn).Count() > 0;
}

In Insert and Update method, I call IsComputerFQDNRegistered, like this:

public void InsertComputer(Computer computer)
{
    if (IsComputerFQDNRegistered(computer.FQDN))
    {
        ValidationResult error = new ValidationResult("FQDN ist bereits vorhanden!", new string[] { "FQDN" });
        throw new ValidationException(error, null, computer);
    }

    if ((computer.EntityState != EntityState.Detached))
    {
        _qmsEntities.ObjectStateManager.ChangeObjectState(computer, EntityState.Added);
    }
    else
    {
        _qmsEntities.Computer.AddObject(computer);
    }
}

Now I change one FQDN in UXGridView and leave the row to save the changes. I get a Errormessage (see UXGridViewErrorMessageValitationError.png). I would like display the ValidationResult ErrorMessage (FQDN ist bereits vorhanden). Where can I find this Info?

After clicking OK on Errormessage, I can not see any errors in UXGridView. Only when I mark the row (with Errors) and change in edit mode, the Errormessage will displayed. But in the UXGridView Footer I can not see the message (please have a look at attached picture (2)). It is possible to change this behavoir? It would be great, when the background color would be red.

Thanks for help

UXGridView UpdateRow is not fired

mg@hsig.ch — Wed, 02 Nov 2011 03:52:41 GMT

I have a UXGridView and for each column a FieldLabel (please see attached picture).
The changes I make on FieldLabel will be synchronized directly with the UXGridView. But the Row is not in edit mode. The events ValidateRow and UpdateRow are not fired!
I want the same behavior as when I change a cell in UXGridView and leave the row
How can I do this?

Update: I could display the FieldLabel read-only and only editable in edit mode. I have not found a property like "IsEditMode".

Here some code:

UXGridView: Visability UXMenuItem

mg@hsig.ch — Fri, 28 Oct 2011 04:47:14 GMT

I have added a new UXMenuItem to the UXGridViewContextMenuStyle in blend (see DuplicateRowCommand).

<Style x:Key="UXGridViewContextMenuStyle" TargetType="Intersoft:UXGridViewContextMenu">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Intersoft:UXGridViewContextMenu">
                <Grid x:Name="RootElement">
                    <Intersoft:UXContextMenu x:Name="ContextMenuElement" IsOpen="{TemplateBinding IsOpen}">
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.SortAscending" Header="{Binding ContextMenu_SortAscending, Source={StaticResource GridViewResource}}" Icon="/QMS;component/Assets/Images/16/sort_az_ascending2.png"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.SortDescending" Header="{Binding ContextMenu_SortDescending, Source={StaticResource GridViewResource}}" Icon="/QMS;component/Assets/Images/16/sort_az_descending.png"/>
                        <Intersoft:UXSeparator x:Name="GroupSeparator"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.GroupByBox" Header="{Binding ContextMenu_GroupByBox, Source={StaticResource GridViewResource}}" IsCheckable="True"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.Group" Header="{Binding ContextMenu_Group, Source={StaticResource GridViewResource}}"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.Ungroup" Header="{Binding ContextMenu_Ungroup, Source={StaticResource GridViewResource}}"/>
                        <Intersoft:UXSeparator x:Name="EditingSeparator"/>
                        <Intersoft:UXMenuItem x:Name="CopyRowItem" Command="local:UXGridViewContextMenuCommands.CopyRow" Header="{Binding ContextMenu_CopyRow, Source={StaticResource GridViewResource}}" Icon="/QMS;component/Assets/Images/16/clipboard_add.png"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.Edit" Header="{Binding ContextMenu_Edit, Source={StaticResource GridViewResource}}" Icon="/QMS;component/Assets/Images/16/pencil.png"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.Delete" Header="{Binding ContextMenu_Delete, Source={StaticResource GridViewResource}}" Icon="/QMS;component/Assets/Images/16/delete.png"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.Update" Header="{Binding ContextMenu_Update, Source={StaticResource GridViewResource}}" Icon="/QMS;component/Assets/Images/16/check.png"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.Cancel" Header="{Binding ContextMenu_Cancel, Source={StaticResource GridViewResource}}" Icon="/QMS;component/Assets/Images/16/delete.png"/>
                        <Intersoft:UXMenuItem Visibility="{Binding ElementName=CopyRowItem,Path=Visibility}" Command="{Binding DuplicateRowCommand}" CommandParameter="{Binding SelectedItem}" Header="Duplizieren" Icon="/QMS;component/Assets/Images/16/element_copy.png"/>
                        <Intersoft:UXSeparator x:Name="BatchUpdateSeparator"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.SaveChanges" Header="{Binding ContextMenu_SaveChanges, Source={StaticResource GridViewResource}}" Icon="/Intersoft.Client.UI.Data;component/Resources/savechanges.png"/>
                        <Intersoft:UXMenuItem Command="local:UXGridViewContextMenuCommands.RejectChanges" Header="{Binding ContextMenu_RejectChanges, Source={StaticResource GridViewResource}}" Icon="/Intersoft.Client.UI.Data;component/Resources/rejectchanges.png"/>
                    </Intersoft:UXContextMenu>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

It works great. I have only the problem that the menu item is always visible (see attached picture).

A simple solution would be a visability-binding to CopyRow. But I am not so happy about this...

<Intersoft:UXMenuItem x:Name="CopyRowItem" Command="local:UXGridViewContextMenuCommands.CopyRow" Header="{Binding ContextMenu_CopyRow, Source={StaticResource GridViewResource}}" Icon="/QMS;component/Assets/Images/16/clipboard_add.png"/>
<Intersoft:UXMenuItem Visibility="{Binding ElementName=CopyRowItem,Path=Visibility}" Command="{Binding DuplicateRowCommand}" CommandParameter="{Binding SelectedItem}" Header="Duplizieren" Icon="/QMS;component/Assets/Images/16/element_copy.png"/>

Can I find out which context menu (row or header) appears to control the visibility of items?

Thanks.

UXGridView refresh button problem

mg@hsig.ch — Mon, 17 Oct 2011 02:09:41 GMT

When I click the refresh button of UXGridView, the data is reloaded, but the view is not refreshed! Cache problem? How can I change this behavior?

This is the response from domain service:

The UXGridView shows still XXXX00. Have a look at attached picture.

reproducible test steps:

- Load data
- Record changed directly into SQL DB (Simulation of multiuser application)
- Refresh button clicked

Environment:

- SQL Server 2008 R2
- Entity Framework 4
- Domainservice (Ria Services)
- ClientUI MVVM Business Application (Silverlight)

Refresh Button works fine with "new item" and "delete item". This behavior occurs only with "edit item".
