# CheckBoxList Control in ASP.Net

## CheckBoxList Control in ASP.Net

The [Checkbox](https://www.mindstick.com/articles/291/how-should-use-checkbox-control-in-vb-dot-net) List [control](https://yourviews.mindstick.com/view/83439/bipartisan-gun-control-bill-passed-in-us-after-decades) is used to create a multi-[selection](https://www.mindstick.com/blog/60/populate-records-in-second-listbox-according-to-the-selection-in-first-list-box) [check](https://yourviews.mindstick.com/view/81033/coronavirus-does-not-check-religion) box group. The Checkbox List [Web server](https://www.mindstick.com/articles/23199/digital-personal-server-the-premium-web-server) control displays a number of checkboxes at once.

<asp:[CheckBoxList](https://www.mindstick.com/forum/352/i-need-to-display-my-checkboxlist-selected-items-in-a-label-how-to-do) ID="CheckBoxList1" runat="server">

<asp:[ListItem](https://www.mindstick.com/forum/23267/insert-a-listitem-to-a-dropdownlist)>c</asp:ListItem>

<asp:ListItem>c#</asp:ListItem>

<asp:ListItem>j#</asp:ListItem>

<asp:ListItem>vb</asp:ListItem>

</asp:CheckBoxList>

## CheckBoxList Event:

Checkbox List control raises a SelectedIndexChanged event when users select any check box in the list. By default, the event does not cause the form to be posted to the server, although you can specify this option by setting the AutoPostBack property to true.

<asp:CheckBoxList ID="CheckBoxList1" runat="server" AutoPostBack="True"

onselectedindexchanged="CheckBoxList1_SelectedIndexChanged">

<asp:ListItem>c</asp:ListItem>

<asp:ListItem>c#</asp:ListItem>

<asp:ListItem>j#</asp:ListItem>

<asp:ListItem>vb</asp:ListItem>

</asp:CheckBoxList>

<asp:Label ID="Label1" runat="server"></asp:Label>

protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e)

{

Label1.Text = CheckBoxList1.SelectedItem.Text;

}

When you check the [option](https://www.mindstick.com/forum/158788/what-is-rust-s-option-type-and-how-is-it-used-for-handling-nullable-values) given in CheckBoxList then SelectedIndexChanged event will fire and [selected value](https://www.mindstick.com/forum/525/get-selected-value-of-datagridviewcomboboxcolumn) will be displayed in the Label

## We can change CheckBoxList appearance:

<asp:CheckBoxList ID="CheckBoxList1" runat="server" Font-Bold="True"

Font-Italic="True" ForeColor="Red">

<asp:ListItem>c</asp:ListItem>

<asp:ListItem>c#</asp:ListItem>

<asp:ListItem>j#</asp:ListItem>

<asp:ListItem>vb</asp:ListItem>

</asp:CheckBoxList>
