Hi,

I have a RadPageView with several RadGrid controls on each page. I am trying to accomplish a few things:

1. Add a CommandItem button but still have the default "refresh" button as well as have the buttons created from CommandItemSettings-AddNewRecordText and ShowExportToPdfButton. Defining a CommandItemTemplate removes these buttons.

2. I want to Hijack the functionality of the CommandItem button created by ShowExportToPdfButton and call my own PDF export method/handler.

3. Since there will be many Grids, how can I hijack each grid's ShowExportToPdfButton and identify which grid to export from the same export method?

Basically, I want a generic way to hijack each Grid's ShowExportToPdfButton or insert into each grid's CommandItem bar a generic exportPDF button that I define.

An add on question is how to find the width of each visible column that is to be exported so that I can set the grid.ExportSettings.Pdf.PageWidth accordingly.

Thanks for any advice.

Hi Jayesh, thanks for the reply, you have given me some good ideas. I will look into creating a single RadGrid_ItemCommand to be used by all the grids.

Thanks

So far things are going ok, but some of the grids have an EditCommandColumn and/or GridButtonColumn and I want to hide these from the export. I am searching and I am not finding a good answer as to when and how to do this.

Updated: Ok I think I have solved the issues now thanks.

foreach (GridColumn gc in grid.MasterTableView.Columns)
{
    bool hideColumn = false;
    if (gc is GridEditCommandColumn) { hideColumn = true; }
    else if (gc is GridButtonColumn) { hideColumn = true; }
 
    if (hideColumn) { gc.Visible = false; }
 
    if (gc.Visible)
    {
        pageWidth += (int)gc.HeaderStyle.Width.Value;
    }
}

foreach (GridColumn gc in grid.MasterTableView.AutoGeneratedColumns)
{
    if (gc.Visible)
    {
        pageWidth += (int)gc.HeaderStyle.Width.Value;
    }
}
