I was searching for select/deselect all checkboxes code into a gridview. I found most of them only provide to select and deselet all the checkboxes if any of the checkbox is unselected into grid the main checkbox is not affecting.
I further try to search some useful code but could not found any useful solution, some of them are selecting all the checkboxes on the page or some provides only to select and deselect but no code to deselect the main checkbox on deselecting any checkbox in grid. Let's do the complete code for it.
Here is my HTML
<asp:GridView ID="gvProducts" runat="server" AutoGenerateColumns="false"> <Columns> <asp:TemplateField ItemStyle-Width="10px"> <HeaderTemplate> <input type="checkbox" id="chkAll" onclick="CheckUncheck(this);" /> </HeaderTemplate> <ItemTemplate> <asp:CheckBox ID="chkItems" runat="server" onclick="ItemClicked(this,'chkAll');" /> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="Product" HeaderText="Product" /> <asp:BoundField DataField="Price" HeaderText="Price" /> <asp:BoundField DataField="Quantity" HeaderText="Quantity" /> </Columns> </asp:GridView>
This will select and de-select all the grid checkboxes on selecting/de-selecting the header checkbox. Header checkox will automatically checked or un-checked on select all the item in grid or de-selecting any item into the grid.
