Well having two checkboxs,  but only one is allowed to be clicked at once sounds alot like radio buttons.

Look at this link for more information about radio buttons.

totally agree with Thomas
the design seems to be wrong because such a requirement can be better fulfilled by radio buttons

hello, experts,
i dont have time to correct and change to radio buttons,
i made a mistake, i 'll try to change that later.

I noticed that when displaying id of checkboxes, names for two checkbox on the same line
will have allmost the same name.
i 've try to work with that name in order to uncheck the correspondant(the one on the same line, row)

here's my function, but it 's not changigin my checkboxe as it should,  what ''s wrong?
is there anything to do with the binding?

in a row, two checkboxes on a line would have for instance :
  //DrainGrid_ctl03_chkToValidate
//DrainGrid_ctl03_chkToDelete

function toogle(obj){
    var prefixDrain = "DrainGrid_";  
    var suffixV = "_chkToValidate";
    var suffixD = "_chkToDelete";    
   
    var name = obj.id;
   
    if(name.search("_chkToValidate") > 1 ){
        var ctlId = name.split("_")[1]; // ctrlId.
        var complete = prefixDrain + ctlId + suffixD;
        //alert(complete)
        var corrDel = document.getElementById(complete);
        if(corrDel.checked)
            corrDel.cheked = false;
    }
    if(name.search("_chkToDelete") > 1 ){
        var ctlId = name.split("_")[1]; // ctrlId.
        var complete = prefixDrain + ctlId + suffixV;
        //alert(complete)
        var corrVal = document.getElementById(complete);
        if(corrVal.checked)
            corrVal.cheked = false;
    }
   
}

i also try by the method : UncheckAll(DataGrid controlGrid)  cf.code attached
is it my use of the method that has a problem?

i attached my code behind page,

            foreach (DataGridItem item in controlGrid.Items)

                            ((CheckBox) c).Checked = false;
