Hi ,

I have a grid and i'm exporting the records of which to an excel sheet with the following code....

private void Export()
        {
            try
            {
                SaveFileDialog dialog = new SaveFileDialog();
                dialog.DefaultExt = "xls";
                dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", "xls", "Excel");
                dialog.FilterIndex = 1;

                if (dialog.ShowDialog() == true)
                {
                    using (Stream stream = dialog.OpenFile())
                    {
                        GridViewExportOptions exportOptions = new GridViewExportOptions();
                        exportOptions.Format = ExportFormat.Html;

exportOptions.ShowColumnHeaders = true;
exportOptions.ShowGroupFooters = true;

                        radGridViewTaskStatus.Export(stream, exportOptions);
                    }
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }

}

I have a column which displays color in it's cell template and I need to export it's hexadecimal code to the excel sheet..
The code of the grid is as follows,

<telerik:RadGridView Name="radGridViewTaskStatus" telerik:StyleManager.Theme="Office_Blue"

AutoGenerateColumns="False"

IsReadOnly="True"

RowHeight="17"

ShowColumnFooters="True"

FontSize="11"

FontFamily="Arial"

Margin="41,0,39,10" Grid.Row="2"

VerticalAlignment="Top"

AddingNewDataItem="radGridViewTaskStatus_AddingNewDataItem"

ItemsSource="{Binding}"

FieldFilterEditorCreated="radGridViewTaskStatus_FieldFilterEditorCreated"

SelectionChanged="radGridViewTaskStatus_SelectionChanged" DataLoaded="radGridViewTaskStatus_DataLoaded">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Status" Width="*" IsReadOnly="True" DataMemberBinding="{Binding Path=Status,Mode=TwoWay,Converter={StaticResource TrimConverter}}">

<telerik:GridViewDataColumn.AggregateFunctions>

<telerik:CountFunction Caption="Count: " />

</telerik:GridViewDataColumn.AggregateFunctions>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn Header="Order" DataMemberBinding="{Binding Path=Order,Mode=TwoWay,Converter={StaticResource TrimConverter}}" />

<telerik:GridViewCheckBoxColumn Header="Complete" DataMemberBinding="{Binding Path=Complete,Mode=TwoWay,Converter={StaticResource YesNoStringToBooleanConverter}}" EditTriggers="CellClick" AutoSelectOnEdit="True" />

<telerik:GridViewDataColumn Header="Colour" Width="100">

<telerik:GridViewColumn.CellTemplate >

<DataTemplate>

<StackPanel Height="17" Background="{Binding Path=Colour,Mode=TwoWay,Converter={StaticResource IntegerToColourConverter}}" Width="Auto">

</StackPanel>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

<telerik:GridViewColumn.CellEditTemplate >

<DataTemplate>

<StackPanel Background="{Binding Path=Colour,Mode=TwoWay,Converter={StaticResource IntegerToColourConverter}}" Width="Auto">

<Button Width="Auto" Height="Auto" Content="..." Margin="2" Name="radBtnSetColor" Click="radBtnSetColor_Click" HorizontalAlignment="Right" ></Button>

</StackPanel>

</DataTemplate>

</telerik:GridViewColumn.CellEditTemplate>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

But when I export to excel, the color is beign displayed as taskstatus1, taskstatus15 and so on..

Is there any way to format this into a hexadecimal or an integer color code... ?

Thanks in Advance,
Ramya

Hello Ramyashree,

The default behavior of our exporting mechanism, when colors are concerned, is to export colors' hexadecimal values as an exporting value. This can be reproduced with the attached project that I have prepared for you. You may try subscribing to the ElementExporting event of RadGridView, in order to easily operate with the exported values. Could you please share with us the implementation of your business object that is being exported?

All the best,
