DataMemberBinding multibinding

[masha reznik]

Hello,
how i can multi bind a column? I tried the to set multibinding to DataMemeberBinding but i gives me a compilation error

<tel:GridViewColumn.DataMemberBinding>
     <MultiBinding Converter="{StaticResource PriceByCurrency}" Mode="OneWay">
            <Binding Path="Price"/>
            <Binding Path="DefaultCurrency"/>
      </MultiBinding>
</tel:GridViewColumn.DataMemberBinding>

Thanks

Hi masha reznik,


MultiBinding is not supported as column binding. However I am sure we can find a workaround for your scenario.

Instead of binding to two different properties of the underlying object ( e.g. price and currency) , you may bind to the object itself and perform your logic in the IValueConverter.
In fact a very similar scenario is demonstrated in the following blog post. Hope you find it helpful.

Let me know in case you need further assistance.

Hello,

while searching a result for this problem i tried this solution.

I hope it is helpful for some of you:

<telerik:GridViewDataColumn Header="AHeader" Width="auto" >
    <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate >
            <TextBlock>
                <TextBlock.Text>
                    <MultiBinding StringFormat=" {0} - {1}">
                        <Binding Path="Price"/>
                        <Binding Path="DefaultCurrency"/>
                    </MultiBinding>
                </TextBlock.Text>
            </TextBlock>
        </DataTemplate>
    </telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>

Hello Christian,

Thank you for sharing this solution ! Indeed it is perfect for the case where you need just to display data.

By "not supported" I meant the default editing mechanisms ( in the case of two way binding ) of RadGridView will mess up .

Hello I tried bindinng to the object itself using a IValueConverter. I Added a column using code:

                GridViewDataColumn columnNotice = new GridViewDataColumn();
                Binding bindingNotice = new Binding(".");  // the object
                bindingNotice.Converter = new NoticeConverter();
                bindingNotice.ConverterParameter = this;
                columnNotice.DataMemberBinding = bindingNotice;
                columnNotice.Header = "Notice";
                columnNotice.ShowDistinctFilters = true;
                columnNotice.ShowFieldFilters = true;
                columnNotice.IsFilterable = true;
                this.mygridview.Columns.Add(columnNotice);

The problem is the column filters not appeared, Although ShowDistinctFilters and ShowFieldFilters are both true

can anyone help me with that?

Thanks

Hi Alfredo,

 

You may take a look at the following forum thread "Column Filter not activated when using converter binding" for further reference.
