How Can I Call A Javascript Function When Checkbox Is Checked

How can I call a Javascript function when a checkbox is checked when this checkbox is inside a gridview ? protected void AlteraStatusExpiraSeteDias_Click(object sender, EventArgs e

Solution 1:

Add onclick attribute to Checkbox markup and include the javascript function that you'd like to call.

<asp:CheckBoxID="chkExpiraTresDias"runat="server"onclick="alert('Foo')" />

Solution 2:

this should help you

$('input:checkbox[ID$="chkExpiraTresDias"]').change(function() { alert('Hello world!'); });

Solution 3:

I fear that you will have to iterate through the Gridview when your "Insert" button is clicked and then do what you have to do. Something like this:

foreach (GridViewRow row inthis.grdImoveis2.Rows) {
    if (row.RowType == DataControlRowType.DataRow) {

        CheckBox chk = row.Cells(0).FindControl("chkExpiraTresDias");
        if (chk != null) {
            Response.Write(chk.Checked); //Do what you gotta do here if it's checked or not
        }
    }
}

Good luck.
