jqgrid select checkbox

Question

I have a checkboxes on my grid by ways of having the following code:

     colNames: [..., 'Select'],
     ...
     ...

     { name: 'act', index: 'act', width: 30, sortable: false }
     ....

     <input type="button" id="bUpload" value="Upload Report" />

What the user clicks on the Upload button, and the user has multiple checkboxes selected for this column, I like to show a message. I am not sure how to do this.

I tried the following but

     $("#bUpload").click(function() {

       var selectedRow;

       if ($("input:checked").length > 1)
       {
          alert('Error -  Please select only one row.');
          return false;
       }


       if ($("input:checked").length > 0) 
       {              
          $("input:checked").each(function() 
          {
             selectedRow = this.value ;
          });
        }    

....

This works but the reason why I do not like this is because I can have other checkboxes for other columns as well to where there can be confusion as to if they selected from the 'act' column or not. How do I say if the column is for 'act' then check how many were selected.

Could you post more implementation details? The current code seems very suspected at least because the checkbox button has id attribute. At the first look the usage of formatter: "checkbox", formatoptions: {disabled: false} would be the best choice for you. You can use additionally beforeSelectRow or onCellSelect to catch checking of the checkboxes. – Exhortative

You could iterate through each row on the grid and test each row.

//iterate over each row 
var rowIds = $('#gridName').jqGrid('getDataIDs');

for (i = 1; i <= rowIds.length; i++) {
    rowData = $('#gridName').jqGrid('getRowData', i);

    if(rowData['act'] //etc..checkbox check) {

    }//if
}//for

Thanks but this does not seem to work. Why are we passing i. Shoudn't it be the value of each rowId? – Eustatius

I is the number of the row, as you are iterating over each row of the grid. This then lets you check the value of the cell you care about. – Excruciation

Where can I use this.Value in order to get the value of what was checked? – Eustatius
