Check/Uncheck RadComboBox items

[Venkatesh]

I have a ASP Dropdown list and Telerik RadComboBox. Both are binding same values.

Now I want to select same value in RadComboBox which user select in ASP Dropdown list.

I have used below codes but RadComboBox always shows previous selcted value only.

1. protected void ddlList_SelectedIndexChanged(object sender, EventArgs e)
     {
          string Name = ddlList.SelectedItem.Text;
        rcbComboBox.ClearCheckedItems();
         rcbComboBox.Text = string.Empty;
         rcbComboBox.Text = Name;
         rcbComboBox.Items.FindItemByText(Name).Checked = true;
        rcbComboBox.Items.FindItemByText(Name).Selected = true;
     }

 

2. protected void ddlList_SelectedIndexChanged(object sender, EventArgs e)
     {

        rcbComboBox.Text = string.Empty;
rcbComboBox.Text = Name;
foreach (RadComboBoxItem rcbItem in rcbComboBox.Items)
{
   if (rcbItem.Text == Name)
   {
       rcbItem.Checked = true;
   }
   else
   {
       rcbItem.Checked = false;
   }
}

     }

 

ComboBox:

<telerik:RadComboBox ID="rcbComboBox" runat="server" CheckBoxes="true" OnItemChecked="rcbComboBox_ItemChecked" AutoPostBack="true"
                    EmptyMessage="Qualifier Filter" DataTextField="OWNER_TYPE" OnItemDataBound="OnItemDataBound" AllowCustomText="true" >
                </telerik:RadComboBox>

 

DropDownList:

<asp:DropDownList ID="ddlList" OnSelectedIndexChanged="ddlList_SelectedIndexChanged" AutoPostBack="true" DataTextField="OWNER_TYPE" DataValueField="OWNER_TYPE" runat="server" Width="70px">
</asp:DropDownList>

Hello Venkatesh,

At my end your code works correctly: after selecting an item in the asp:DropDownList the item with the same Text in the ComboBox is checked. Here's a short video that demonstrates this.
I attached a sample runnable page, in which I tested your code. Note also that if CheckBox support is enabled the ComboBox items' Checked property has to be used instead of Selected.
