ASP.NET 3.5 GridView Row Selection

Question

I have a GridView . I have to collect the GridViewRow where checkbox is selected. How can I achieve it without any client side script? Please help me to get this done.

Answer 1

If you are familiar with LINQ,you can get this something like

List<GridViewRow> rowCollection = 
                     GridView1.Rows
                     .OfType<GridViewRow>()
                     .Where(x => ((CheckBox)x.FindControl("chkRow")).Checked)
                     .Select(x => x).ToList();

All the best.

Answer 2

另一种老式方法是使用for或foreach循环遍历网格的Rows集合，使用FindControl方法找到复选框并检查其Checked属性值。

Answer 3

Simple and easy to understand when you come back to it later.

 var selectedRows = (from GridViewRow row in GridView1.Rows
                    let cbx = (CheckBox)row.FindControl("CheckBox1")
                    where cbx.Checked
                    select row).ToList();

Bare in mind that for this to work I think you'll need to convert the column containing the checkbox into a template column.
