hello,

I have a multi-columns Radcombobox like :

    
            <telerik:RadComboBox  Width="556px"  ID="Exp_Code" runat="server" Height="190px" Skin="Sunset" 
        
                                     MarkFirstMatch="true"  EnableLoadOnDemand="true" HighlightTemplatedItems="true" 
        
                                    ItemRequestTimeout="1"  OnItemsRequested="Exp_Code_ItemsRequested" OnItemDataBound="Exp_Code_ItemDataBound" DataSourceID="SqlDataSource1" CollapseDelay="1" ExpandDelay="1">  
        
                                    <HeaderTemplate> 
        
                                        <ul> 
        
                                         <li class="col1">Code</li> 
        
                                         <li class="col2">Nom</li> 
        
                                         <li class="col3">CP</li> 
        
                                         <li class="col4">Ville</li> 
        
                                         <li class="col5">Pays</li> 
        
                                        </ul> 
        
                                    </HeaderTemplate> 
        
                                    <ItemTemplate> 
        
                                        <ul> 
        
                                         <li class="col1"><%# DataBinder.Eval(Container.DataItem, "Tiers") %></li>  
        
                                         <li class="col2"><%# DataBinder.Eval(Container.DataItem, "Nom") %></li>  
        
                                         <li class="col3"><%# DataBinder.Eval(Container.DataItem, "CP") %></li>  
        
                                         <li class="col4"><%# DataBinder.Eval(Container.DataItem, "Ville") %></li>  
        
                                         <li class="col5"><%# DataBinder.Eval(Container.DataItem, "Pays") %></li>  
        
                                        </ul> 
        
                                    </ItemTemplate> 
        
                            <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                         </telerik:RadComboBox>

In my function Page_Load(), I have this code :

    
            Exp_Code.Text =  (Tiers + "      ").Substring(0, 12);

I wish on the function Page_Load(), to go to search the corresponding item text like format in function Exp_Code_ItemDataBound :

    
            protected void Exp_Code_ItemDataBound(object sender, RadComboBoxItemEventArgs e)  
        
                    {  
        
                        e.Item.Text = ((DataRowView)e.Item.DataItem)["Tiers"].ToString() + "        - " + ((DataRowView)e.Item.DataItem)["Nom"].ToString() + " - " + ((DataRowView)e.Item.DataItem)["Ville"].ToString();  
        
                        e.Item.Value = ((DataRowView)e.Item.DataItem)["Tiers"].ToString() + "        - " + ((DataRowView)e.Item.DataItem)["Nom"].ToString() + " - " + ((DataRowView)e.Item.DataItem)["Ville"].ToString();  
        
                    }

Thank you for your help.

Hello Thierry Treunet,

Thank you for clarifying.

You could set SelectedValue of the RadComboBox instead of the Text property to the Value of the Item you want to select.

Alternatively you could use the following method to find the first matching Item and select it then:

private RadComboBoxItem FindItemByText(string text)

{

foreach (RadComboBoxItem item in Exp_Code.Items)

if (item.Text.StartsWith(text))

return item;

}

RadComboBoxItem item = FindItemByText((Tiers + " ").Substring(0, 12));

item.Selected = true;

Please have in mind that you have to do either of these *after* the DataBind method of the RCB is called, so that Items are populated.
