Hi Telerik Team,

 

I would like to access grid data which I prefer the converted data.
But while I try to access through the properties "items" or "itemsource" - we got the raw data which it still not be converted.

At the same time the data that I need is all data on view area and out of view area.

 

Could you please give me an example or advice ?

 

Best Regards,

Wanlop Niwatsreesupun

Hello Wanlop,

If you're using a converter for your bindings, you can get ahold of that and use the converted values:

var column = this.clubsGrid.Columns["Name"] as GridViewDataColumn;
var converter = column.DataMemberBinding.Converter;
if (converter != null)
{
    var formattedValue = converter.Convert((this.clubsGrid.SelectedItem as Club).Name, typeof(string), null, CultureInfo.CurrentCulture);
    MessageBox.Show(formattedValue.ToString());
}

On the other hand, if you're formatting the cell values by using the DataFormatString property, you can also use that when accessing the values like so:

var column = this.clubsGrid.Columns["Established"] as GridViewDataColumn;
if (!string.IsNullOrWhiteSpace(column.DataFormatString))
{
    var formattedValue = string.Format(column.DataFormatString, (this.clubsGrid.SelectedItem as Club).Established);
    MessageBox.Show(formattedValue);
}

Please let me know if you find these suggestions helpful.

Hi Dilyan,

Thanks for your suggestion but I have tested but It not good performance.

It still bad performance because we need to loop for all rows and columns to convert these values.

Do you have the other suggestion to export all formatted data with highest performance ?
