XamDataGrid

Ma Liang posted over 12 years ago

Hi,

Here is my settings:

<igDP:XamDataGrid.FieldSettings>
<igDP:FieldSettings CellClickAction="SelectCell" LabelClickAction="SelectField"/>
</igDP:XamDataGrid.FieldSettings>

And here are my styles:
<Style TargetType="{x:Type igDP:CellValuePresenter}">
            <Style.Triggers>
                <DataTrigger Binding="{Binding DataItem.IsChannelEnabled}" Value="False">
                    <Setter Property="IsEnabled" Value="False"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>

When I try to select some cells from the disabled cell, all the records are selected. What I want to archieve is that only the cells are selected not the records?

Is this possible?

Hello Ima,

Thank you for your post. I have been looking into the functionality that you are looking for and in order to be able to select the cells of the XamDataGrid, their CellValuePresenters should be enabled. You can set the IsEnabled property of the CellValuePresenter to True and use one of the following approaches, in order to restrict the editing of cells:

Using the AllowEdit property. You can set the AllowEdit property of the FieldSettings of each field that you wish to be read only. Using this approach you can restrict the cells of a whole field of the XamDataGrid. You can read more details regarding this property, here in our documentation: http://help.infragistics.com/NetAdvantage/WPF/2012.1/CLR4.0/?page=InfragisticsWPF4.DataPresenter.v12.1~Infragistics.Windows.DataPresenter.FieldSettings~AllowEdit.html

If you wish to be able to restrict the ability for editing each individual cell of the XamDataGrid I can suggest using the EditModeStarting event of the XamDataGtid. You can handle this event and in you can apply the logic for checking whether the cell should be editable there. If the cell should not be editable, you can set e.Cancel to true and by doing so, you will not allow the cell to be edited.

I have modified the sample application that you have provided me with in order to demonstrates how you can cancel the editing of the cells, using the same condition that you have applied in the trigger of the Style for the CellValuePresenter, using the second approach that I have described.

If you need any further assistance on the matter, please do not hesitate to ask.

Sincerely,
