Forms Data Controls :: Disable Autopostback Of Checkbox Inside Of GridView During SelectedIndexChanged Of ListView

Sep 8, 2010

I have a checkbox placed inside a gridview:

<GridView><asp:TemplateField HeaderText="Driver"> <ItemTemplate> <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' /> </ItemTemplate> </GridView>

For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked.

Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired.

How could I disable the autopostback of the checkbox during the listview item changed.
