Regarding the selected rows count, you could use the SelectedRows property in the multiple selection WebGrid. However, it will also exhibit the same issue as you described. A workaround will be to filter the unique key value of each selected row so we will only count the unique key value. Here is the snippet:

for(var i = 0; i < grid.RootTable.SelectedRows.length; i++)
{
    var keyVal = grid.RootTable.SelectedRows[i].getAttribute('keyValue');
    
    if(strKeyList.indexOf(keyVal + ";") < 0)
        strKeyList += grid.RootTable.SelectedRows[i].getAttribute('keyValue') + ";"
}

var strKeyArr = strKeyList.split(";");
alert(strKeyArr.length - 1);

In order to clear selection in a WebGrid with classic paging, you will need to use the ClearSelection method and SelectedRows.Clear from WebGrid table Storage property. In your case, for multiple selection you will need to reselect one of the selected row before invoking ClearSelection so all the selected row will be cleared. Here is the snippet:

function ClearSelection()
{
    var grid = ISGetObject("wgTest");

    var strKeyList = "";

    for (var i = 0; i < grid.RootTable.SelectedRows.length; i++)
    {
        var keyVal = grid.RootTable.SelectedRows[i].getAttribute('keyValue');

        if (strKeyList.indexOf(keyVal + ";") < 0)
            strKeyList += grid.RootTable.SelectedRows[i].getAttribute('keyValue') + ";"
    }

    var strKeyArr = strKeyList.split(";");
    
    var rowKeyObj = new Array();

    for (var j = 0; j < strKeyArr.length - 1; j++)
    {
        var currRowObj = grid.RootTable.GetRowByKeyValue(strKeyArr[j]);
        if (currRowObj)
        {
            rowKeyObj.push(currRowObj);
        }
    }

    if (rowKeyObj.length > 0)
    {
        rowKeyObj[0].Select();
        grid.ClearSelection();

        for (var k = 0; k < rowKeyObj.length; k++)
        {
            rowKeyObj[k].Uncheck();
        }
    }

    grid.RootTable.Storage.SelectedRows.Clear();
}

Hi,

Thank you for your reply.

I am trying the code to clear the row selection stated above. Can you please tell me in which client side event should I be adding this code. I tried to call the above function "ClearSelection()" during "OnAfterResponseProcess" event, which clears the selection, but it reappears after the page finishes loading. When I put an alert in the end of the "ClearSelection()" method, the selection is cleared, but as soon as the page finishes loading it appears back.

FYI: I am using "RestoreRowSelection = "ALL" 

Thanks and appreciate your help

Regards

Dhaval.
