How to limit text length in grid column while not limiting the same text in Excel Export

Question

I'm currently building an asp.net application with a large amount of data in a Telerik RadGrid. A number of the columns in my grid contain large amounts of text. To limit the size of the text in those columns (and to preserve the format of the grid) I truncate each field in the ItemDataBound(...) method in the following piece of code:

if (item["Title"].Text.Length > 21)
    item["Title"].Text = item["Title"].Text.Substring(0, 21);

if (item["Investigation_Results"].Text.Length > 30)
    item["Investigation_Results"].Text = item["Investigation_Results"].Text.Substring(0, 30);

if (item["Resolution_Steps"].Text.Length > 30)
    item["Resolution_Steps"].Text = item["Resolution_Steps"].Text.Substring(0, 30);

The problem is that when using the Excel export functionality of the RadGrid, the fields that are being truncated are also truncated in the exported csv.

Q: How can I have the data truncated in the grid view, but in full when exporting to Excel?

Additional Info:

Export is called on this button click event:

protected void imgbtnexcel_Click(object sender, ImageClickEventArgs e)
{
    ConfigureExport();
    RadGridActionItem.MasterTableView.ExportToExcel();
}

protected void ConfigureExport()
{
    RadGridActionItem.ExportSettings.ExportOnlyData = true;
    RadGridActionItem.ExportSettings.IgnorePaging = true;
    RadGridActionItem.ExportSettings.OpenInNewWindow = true;
}

Answer 1

I was able to get the functionality I desired by putting a conditional statement (exporting/not exporting) around my "truncating code" in ItemDataBound(...). I then used a global boolean variable and marked it true in the export button click event.

static bool exportBool;

In ItemDataBound(...):

if (ActionItem.exportBool != true) // MK CHANGE
{
    if (item["Title"].Text.Length > 21)
       item["Title"].Text = item["Title"].Text.Substring(0, 21) + "...";

    if (item["Investigation_Results"].Text.Length > 30)
       item["Investigation_Results"].Text = item["Investigation_Results"].Text.Substring(0, 30) + "...";

    if (item["Resolution_Steps"].Text.Length > 30)
       item["Resolution_Steps"].Text = item["Resolution_Steps"].Text.Substring(0, 30) + "...";
}

Export Button Click Event:

protected void imgbtnexcel_Click(object sender, ImageClickEventArgs e)
{
    ActionItem.exportBool = true;
    BindGrid();
    ConfigureExport();
    RadGridActionItem.MasterTableView.ExportToExcel();
}

Note that the boolean is set to false in Page_Load().

Thanks!
