Question

And the script used is

<script type="text/javascript">

        var lastSelection;
        var idCategoria;
        var nomeCategoria;

        function editRow(id) {

                var grid = jQuery("#<%= JQGrid1.ClientID %>");

                if (document.getElementById(lastSelection + "_NomeCategoria") != null) {
                    if ( document.getElementById(lastSelection + "_NomeCategoria").value != undefined ) {
                        var objeto = document.getElementById(lastSelection + "_NomeCategoria");
                        idCategoria = objeto.value;
                        nomeCategoria = objeto[objeto.selectedIndex].text;
                    }

When the rows are not in edit mode the fifth columns shows a link and while editing it shows a dropdown. To select the correct item in the dropdown I use the second column that has the ID that came from the database.

The problem is that after changing the item and saving it to the database, this column value doesn’t change. How can I do it after the grid.saveRow(lastSelection, false); ?

Thanks.

Answer 1

I have found the solution !

I changed the code below

if (lastSelection != undefined) {
    grid.updateGridRows("{IdCategoria:" + idCategoria + "}", lastSelection);
    grid.saveRow(lastSelection, false);
    //grid.setCell(lastSelection, "IdCategoria", idCategoria);
    //grid.setRowData(lastSelection, "{IdCategoria:" + idCategoria + "}");

}

To this

if (lastSelection != undefined) {
    grid.setRowData(lastSelection, {IdCategoria:idCategoria});
    grid.saveRow(lastSelection, false);}

The problem was that I was passing the second parameter as a string.
