Hi Spring gao,

You could use the following Javascript code to accomplish it. (run it when your button click).

function getCheckedValues(){
    // get WebGrid with ID. in this example I use WebGrid1
    var grd = wgGetGridById("WebGrid1");
    var table = grd.GetRootTable();

    //this is the point. get all checked row of your grid.
    var checkedRows = table.GetCheckedRows();
    var result = "";
    for (var i = 0; i < checkedRows.length; i++)
    {
        // append the needed value to result. in this example I use value in column index 3 and index 4.
        result += checkedRows[i].cells[3].innerText +"|"+ checkedRows[i].cells[4].innerText;
        result += ",";
    }
    // remove leading separator (,)
    result = result.replace(/,$/, "");
    // pass all to textarea/input for showing the result. In this example I used textarea tag with id:"textarea"
    document.getElementById("textarea").value = result;
}

That should do the trick.

first,Thank you leo chandra,
but i don't know user click checkbox of head,it's keypoint.
how to know?

Hi Spring gao,

Sorry for my late response.

If you want that script to run whenever checkbox (on checker column) was clicked, you could add OnCheckBoxClick client event which could be access via WebGrid Properties >> LayoutSettings >> ClientSideEvents >> OnCheckBoxClick. Specify JavaScript that you want to run there.

The result reflected on ASP code side would be something like bellow

<LayoutSettings>
<ClientSideEvents OnCheckBoxClick="getCheckedValues()"/>
</LayoutSettings>

Hope this will be useful.

Best Regards,
Leo
