[Solved] Custom Button in RadGridView

[Frederico Policarpo Martins]

Hello,

I have a RadGridView and one of its columns is a button. In the click of this button i need to identify the object bound to the row of the clicked button. But gridView.CurrentItem just work if the row is selected, i need to identify the item of the row where the button was clicked.

My grid is like the follow:

<radGrid:RadGridView Grid.Row="2" CanUserFreezeColumns="False" ColumnsWidthMode="Fill"

x:Name="gridIdeias" IsReadOnly="True" AutoGenerateColumns="False">

<radGrid:RadGridView.Columns>

<radGrid:GridViewDataColumn HeaderText="Titulo" Width="200" DataMemberPath="Titulo"/>

<radGrid:GridViewDataColumn HeaderText="Classificacao"

UniqueName="Classificacao"

DataMemberBinding="{Binding Classificacao, Mode=OneWay, Converter={StaticResource ConversorDeClassificacao}}"

Width="200" DataFormatString="{}{0:g}">

<radGrid:GridViewDataColumn.CellTemplate>

<DataTemplate>

<ComboBox Background="White" BorderThickness="0"

ItemsSource="{Binding Source={StaticResource Conversor}, Path=Values}"

SelectionChanged="AvaliacaoRealizadaEvent"

SelectedItem="{Binding Classificacao,Mode=OneWay, Converter={StaticResource ConversorDeClassificacao}}">

</ComboBox>

</DataTemplate>

</radGrid:GridViewDataColumn.CellTemplate>

</radGrid:GridViewDataColumn>

<radGrid:GridViewDataColumn HeaderText="Avaliacao Geral" Width="200"

UniqueName="ColunaAvaliacaoGeral"

DataMemberPath="AvaliacaoGeral">

<radGrid:GridViewDataColumn.CellTemplate>

<DataTemplate>

<HalfStarSelector:StarSelector ReadOnly="True" Height="20" DisplayValue="{Binding AvaliacaoGeral}"

Value="{Binding AvaliacaoGeral}" SetDisplayValueOnClick="True" Maximum="5"/>

</DataTemplate>

</radGrid:GridViewDataColumn.CellTemplate>

</radGrid:GridViewDataColumn>

<radGrid:GridViewColumn>

<radGrid:GridViewColumn.CellTemplate>

<DataTemplate>

<Button Content="Gerar Relatório" Click="GerarRelatorio"

/>

</DataTemplate>

</radGrid:GridViewColumn.CellTemplate>

</radGrid:GridViewColumn>

</radGrid:RadGridView.Columns>

<radGrid:RadGridView.HierarchyChildTemplate>

<DataTemplate>

<navigation:RadTabControl Height="100">

<navigation:RadTabItem Header="Descricao">

<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="{Binding Descricao}" />

</navigation:RadTabItem>

<navigation:RadTabItem Header="Justificativa">

<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="{Binding Justificativa}" />

</navigation:RadTabItem>

<navigation:RadTabItem Header="Exemplo">

<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="{Binding Exemplo}" />

</navigation:RadTabItem>

</navigation:RadTabControl>

</DataTemplate>

</radGrid:RadGridView.HierarchyChildTemplate>

</radGrid:RadGridView>

And this is the handler for the GerarRelatorio event:

private void GerarRelatorio(object sender, RoutedEventArgs e)

{

var ideia = (Ideia) gridIdeias.CurrentItem;

// The ideia var isnt the Ideia object of the click row when this row is not selected

}

What can I do to identify the Ideia object of the row of the clicked button ??

Hello Frederico,

You can get the parent GridViewRow object and DataContext will be desired data item using our extension methods:

var gridViewRow = ((Button)sender).ParentOfType<GridViewRow>();

if(gridViewRow != null)
{
   var ideia = (Ideia) gridViewRow.DataContext;
}
