How
to use RadioButtonList control and do transaction on RadioButtonList using
asp.net c# code
Step 1 : First create your website
in asp.net and create one .aspx page .
Step2: Open .aspx page and add
RadioButtonList control.
<asp:RadioButtonList
ID="rbList" runat="server" AutoPostBack="True"
OnSelectedIndexChanged="rbList_SelectedIndexChanged"></asp:RadioButtonList>
Step 3 : And add buttons control to
do transaction on RadioButtonList.
<asp:Button
ID="BtnAdd" runat="server" OnClick="BtnAdd_Click"
Text="Add Item" />
<asp:Button ID="BtnDelete" runat="server" Text="Delete Selcted" OnClick="BtnDelete_Click" />
<asp:Button ID="BtnDelete" runat="server" Text="Delete Selcted" OnClick="BtnDelete_Click" />
Step 4 :Add server side code to
handle button event.
protected void
BtnAdd_Click(object sender, EventArgs e)
{
ListItem litem = new ListItem();
itemAdded++;
litem.Text = "Item" + itemAdded;
litem.Value = "Item" + itemAdded;
rbList.Items.Add(litem);
lblMessage.Text = "Item addedd = " + litem.Value.ToString();
}
protected void BtnDelete_Click(object sender, EventArgs e)
{
for (int i = 0; i < rbList.Items.Count; i++)
{
if (rbList.Items[i].Selected == true)
{
lblMessage.Text = "Item deleted = " + rbList.Items[i].ToString();
rbList.Items.RemoveAt(i);
break;
}
}
}
protected void rbList_SelectedIndexChanged(object sender, EventArgs e)
{
lblMessage.Text = "Selected value = " + rbList.SelectedValue.ToString();
}
{
ListItem litem = new ListItem();
itemAdded++;
litem.Text = "Item" + itemAdded;
litem.Value = "Item" + itemAdded;
rbList.Items.Add(litem);
lblMessage.Text = "Item addedd = " + litem.Value.ToString();
}
protected void BtnDelete_Click(object sender, EventArgs e)
{
for (int i = 0; i < rbList.Items.Count; i++)
{
if (rbList.Items[i].Selected == true)
{
lblMessage.Text = "Item deleted = " + rbList.Items[i].ToString();
rbList.Items.RemoveAt(i);
break;
}
}
}
protected void rbList_SelectedIndexChanged(object sender, EventArgs e)
{
lblMessage.Text = "Selected value = " + rbList.SelectedValue.ToString();
}
Step 5 : Just run your page and try
to check your code.
