RadComboBox Selected Item

[Johnny]

hi i dynamically create RadComboBox and fill items then set SelectedItem if the SelectedItem Exist on the database
next time i click another link on again i clear all dynamic items again i create dynamic controls
but the problem is second time created Combobox holds the selectedItem of First time created Combobox
how to solve this problem?

Hi Johnny,

You could save the value of the previously selected item in a hidden field. Then, on pageLoad event, you could get the information about the item from the hidden field, and set that item as selected.

The most appropriate moment to save information about the currently selected item is on the SelectedIndexChanged server or client-side event.

Hello,

Try the following.
ASPX:

<asp:LinkButton ID="LinkButton1" runat="server" Text="A" OnClick="LinkButton1_Click"></asp:LinkButton>
<asp:LinkButton ID="LinkButton2" runat="server" Text="B" OnClick="LinkButton2_Click"></asp:LinkButton>

C#:

protected void LinkButton1_Click(object sender, EventArgs e)
   {
       RadComboBox combob = new RadComboBox();
       combob.ID = "combo1";
       RadComboBoxItem itm1 = new RadComboBoxItem();
       itm1.Text = "aa";
       itm1.Value = "1";
       combob.Items.Add(itm1);
       RadComboBoxItem itm2 = new RadComboBoxItem();
       itm2.Text = "bb";
       itm2.Value = "2";
       combob.Items.Add(itm2);
       RadComboBoxItem itm3 = new RadComboBoxItem();
       itm3.Text = "cc";
       itm3.Value = "3";
       combob.Items.Add(itm3);
       form1.Controls.Add(combob);
       combob.SelectedValue = "1";
   }
   protected void LinkButton2_Click(object sender, EventArgs e)
   {
       RadComboBox combob = new RadComboBox();
       combob.ID = "combo1";
       RadComboBoxItem itm1 = new RadComboBoxItem();
       itm1.Text = "aa";
       itm1.Value = "1";
       combob.Items.Add(itm1);
       RadComboBoxItem itm2 = new RadComboBoxItem();
       itm2.Text = "bb";
       itm2.Value = "2";
       combob.Items.Add(itm2);
       RadComboBoxItem itm3 = new RadComboBoxItem();
       itm3.Text = "cc";
       itm3.Value = "3";
       combob.Items.Add(itm3);
       form1.Controls.Add(combob);
       combob.SelectedValue = "2";
   }
