ASP.NET Grid - Tutorial: Accessing Selected Records

The selected records can be accessed on client-side and server-side.

Client-Side

There are more ways to access the selected records on the client-side:

SelectedRecords property of the client-side grid object. This Array contains
all the selected records from the grid.

for(var i=0; i<grid1.SelectedRecords.length;i++) {
    var record = grid1.SelectedRecords[i];
    alert(record.OrderID + " --- " + record.ShipName + " --- " + record.ShipCity + " --- " + record.ShipCountry);
}

PageSelectedRecords property of the client-side grid object. This Array contains
all the selected records from the current page.

for(var i=0; i<grid1.PageSelectedRecords.length;i++) {
    var record = grid1.PageSelectedRecords[i];
    alert(record.OrderID + " --- " + record.ShipName + " --- " + record.ShipCity + " --- " + record.ShipCountry);
}

OnClientSelect event. This event receives and array of selected records as the argument.
You need to assign a javascript function to this property: grid1.OnClientSelect="onRecordSelect";

function onRecordSelect(arrSelectedRecords) {
    for(var i=0; i<arrSelectedRecords.length;i++) {
        var record = arrSelectedRecords[i];
        alert(record.OrderID + "---" + record.ShipName +  "---" + record.ShipCity + "---" + record.ShipCountry);
    }
}

Server-Side

There are more ways to access the selected records on the server-side:

SelectedRecords property of the grid object. This ArrayList contains
all the selected records from the grid.

if(grid1.SelectedRecords != null)
    {
        string sText = "These are the selected records (server-side):";
        foreach(Hashtable oRecord in grid1.SelectedRecords)
        {
            sText += "<br />" + oRecord["OrderID"] + " --- " + oRecord["ShipName"] + 
            " --- " + oRecord["ShipCity"] +  " --- " + oRecord["ShipCountry"];
        }

        divSelectedRecords.Text = sText;
    }

OnSelect event. This event is executed when the page is posted back,
if there were any records selected. grid1.OnSelect = OnRecordSelected;

void OnRecordSelected(object sender, GridRecordEventArgs e)
{
    string sMessage = "These are the newly selected records (server-side): ";
    if(e.RecordsCollection != null)
    {
        foreach(Hashtable oRecord in e.RecordsCollection)
        {
            sMessage += "
" + oRecord["OrderID"] + " " + oRecord["ShipName"];
        }
    }
    
    Literal oLiteral = new Literal();
    oLiteral.Text = sMessage;
    phSelectedRecords.Controls.Add(oLiteral);
}
