Having XamGrid Cells read only
posted

Hi there,

I am created an application using MVVC and currently using a XamGrid to display email configurations. I want one of the columns in the results to be readonly and not editable. I tried adding the ReadOnly=True on the XAML, but since I have a Add New Row setting aswell, setting this to true, doesnt allow me to input anything in this row when creating a new row. Is there a way to set the readonly property on the results without affecting the ReadOnly column?

Thanks in advance,

Julio

    Hi Julio,

    If I properly understand your question, you need to be able to change a column cell value when adding a row and not changing it in on Editing. This could be achieved using a TemplateColumn with a TextBox as an EditorTemplate and change its IsReadOnly property value starting editing depending on what is started – editing or adding. Here is a sample code snippet:

    <ig:XamGrid x:Name="Grid1" CellEnteredEditMode="Grid1_CellEnteredEditMode" CellExitingEditMode="Grid1_CellExitingEditMode" …………..…>

    ……………………….

    <ig:TemplateColumn Key="PropertyName">

        <ig:TemplateColumn.ItemTemplate>

            <DataTemplate>

                <TextBlock Text="{Binding PropertyName}" />

            </DataTemplate>

        </ig:TemplateColumn.ItemTemplate>

        <ig:TemplateColumn.EditorTemplate>

            <DataTemplate>

                <TextBox x:Name="NameEditorTemplateTextBox" Text="{Binding PropertyName}" IsReadOnly="True" />

            </DataTemplate>

        </ig:TemplateColumn.EditorTemplate>

    </ig:TemplateColumn>

     

    private void Grid1_CellExitingEditMode(object sender, ExitEditingCellEventArgs e)

    {

        if (e.Cell.Column.Key == "Name" && !e.EditingCanceled && e.Cell is AddNewRowCell)

        {

            TextBox tb = e.Editor as TextBox;

            tb.IsReadOnly = true;

        }

    }

     

    private void Grid1_CellEnteredEditMode(object sender, EditingCellEventArgs e)

    {

        if (e.Cell.Column.Key == "Name" && e.Cell is AddNewRowCell)

        {

            TextBox tb = e.Editor as TextBox;

            tb.IsReadOnly = false;

        }

    }

     

    Let me know if this helps.

     

    Thank you!
