Hi!

I need some help on this. I have the checkbox name chkitems: here's the data:

<asp:CheckBoxList runat="server" ID="chkitems" Font-Names="Tahoma" Font-Size="Smaller"
RepeatColumns="3" RepeatDirection="Horizontal">
 <asp:ListItem Value="1">Item 1</asp:ListItem>
 <asp:ListItem Value="2">Item 2</asp:ListItem>
 <asp:ListItem Value="3">Item 3</asp:ListItem>
 <asp:ListItem Value="4">Item 4</asp:ListItem>
 <asp:ListItem Value="5">Item 5</asp:ListItem>
</asp:CheckBoxList>

Below on this script is the button name "cmdSelectedItems". What I want to do is once I click the button(cmdSelectedItems) It should be automatically checked the Items 1,3 and 5.

Please help me.

Thanks in advance.

I'd suggest you do this client side, but if you want to handle this server-side...

aspx

<form id="form1" runat="server">
        <div>
            <asp:CheckBoxList runat="server" ID="chkitems" 
                   Font-Names="Tahoma" Font-Size="Smaller"
                    RepeatColumns="3" RepeatDirection="Horizontal">
                <asp:ListItem Value="1">Item 1</asp:ListItem>
                <asp:ListItem Value="2">Item 2</asp:ListItem>
                <asp:ListItem Value="3">Item 3</asp:ListItem>
                <asp:ListItem Value="4">Item 4</asp:ListItem>
                <asp:ListItem Value="5">Item 5</asp:ListItem>
            </asp:CheckBoxList>
            <asp:Button Text="Select Items" runat="server" 
                    ID="cmdSelectedItems" OnClick="cmdSelectedItems_Click" />
        </div>
        </form>

What language are you developing in? C#?

protected void cmdSelectedItems_Click(object sender, EventArgs e)
{
   chkitems.Items.FindByValue("1").Selected = true;
   chkitems.Items.FindByValue("3").Selected = true;
   chkitems.Items.FindByValue("5").Selected = true;
 }

This is exactly what I've been looking for.

Thank you very much.

Glad you solved your issue.
