I have a radgrid with 3 radiobutton in each row as a group. Either 1 will be selected and rest 2 will be not. My requirement is to show a count of radiobutton's selected for a particular page at the buttom of the grid(not footer). For eg. Not Mine:2, Remove:4, Keep: 4. The way that i thought of iterating through the MasterTable rows and get the radiobutton control but as it is in rad grid I cant get those. Please provide a solution.



Thanks in advance.

I want it to be done in Client side. Server side option can't be possible as there are huge amount of data and doing post back will take a lot of time.

I have written this function but this is not working. Giving error at the bold sections.while compiling. "The name 'rdbNotMine' does not exist in the current context" etc.

function UpdateCount(sender, eventArgs)
    {
        var grid = $find("<%=grvReviewerView.ClientID %>");
        alert("enter");
        var keepAcessCount,removeAcessCount,notMineCount = 0;
        var masterTable = grid.get_masterTableView();
        for(var i=0; i < masterTable.get_dataItems().length; i++)
        {
            var rdbNotMine1 = masterTable.get_dataItems()[i].$find('<%= rdbNotMine.ClientID%>');
            var rdbKeepAccess1 = masterTable.get_dataItems()[i].$find('<%= rdbKeepAccess.ClientID%>');
            var rdbRemoveAcess1 = masterTable.get_dataItems()[i].$find('<%= rdbRemoveAccess.ClientID%>');
            alert(rdbNotMine1);alert(rdbKeepAccess1);alert(rdbRemoveAcess1);
            if(rdbNotMine1.checked)
            {
                notMineCount = eval(notMineCount) + eval(1);
            }
            if(rdbKeepAccess1.checked)
            {
                keepAcessCount = eval(keepAcessCount) + eval(1);
            }
            if(rdbRemoveAcess1.checked)
            {
                removeAcessCount = eval(removeAcessCount) + eval(1);
            }
        }
        document.getElementById('<%= lblKeepAccessCount.ClientID%>').innerHTML = keepAcessCount;
        document.getElementById('<%= lblRemoveAccessCount.ClientID%>').innerHTML = removeAcessCount;
        document.getElementById('<%= lblNotMineCount.ClientID%>').innerHTML = notMineCount;

    }

Hello Debojyoti,

You could access the RadioButton by using the findElement method like below.

JavaScript:

function OnRowClick(sender, args)

{

var count = 0;

var grid = $find("<%=RadGrid1.ClientID %>");

var masterTable = grid.get_masterTableView();

var items = masterTable.get_dataItems();

for (var i = 0; i < masterTable.get_dataItems().length; i++)

{

var radiobtn = items[i].findElement("rdbNotMine");

if (radiobtn.checked)

count++;

}

var label1 = document.getElementById("lblNotMineCount");

label1.innerText = count;

}

Thanks,
Shinu.
