Hi Omer,

Can you try to register LinkButtton as a AsyncPostBackControl:

<telerik:RadComboBox runat="server" ID="combo" OnItemDataBound="combo_ItemDataBound"

DataSourceID="sdsProducts" DataTextField="ProductName" DataValueField="ProductID">

<ItemTemplate>

<asp:LinkButton runat="server" CommandName="Create" Text='<%# Eval("ProductName") %>' ID="LinkBtn" OnClick="LinkBtn_Click"></asp:LinkButton>

</ItemTemplate>

</telerik:RadComboBox>

<asp:SqlDataSource runat="server" ID="sdsProducts" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"

SelectCommand="SELECT [ProductID], [ProductName] FROM [Alphabetical list of products]"></asp:SqlDataSource>

protected void combo_ItemDataBound(object sender, RadComboBoxItemEventArgs e)

{

LinkButton lb = e.Item.FindControl("LinkBtn") as LinkButton;

ScriptManager.GetCurrent(this).RegisterAsyncPostBackControl(lb);

}

protected void LinkBtn_Click(object sender, EventArgs e)

{

}

Thank you for reply
Here is my onitemdatabound event

protected void RadComboBoxAdresses_ItemDataBound(object sender, RadComboBoxItemEventArgs e)

{

if (e.Item is RadComboBoxItem)

this.UpdatePanelAdress.Triggers.Add(trigger);

}

catch

HtmlTableRow trcompanyname = (HtmlTableRow)e.Item.FindControl("trcompanyname");

HtmlTableRow trcompanytaxoffice = (HtmlTableRow)e.Item.FindControl("trcompanytaxoffice");

Only first item firing OnCommandEvent.

I achieve this issue with this codes

//aspx

<input type="button" id="btnDelete"

onclick='<%# String.Format("javascript:return SaveWithParameter(\"{0}\")", Eval("AdressId").ToString()) %>'  value="Sil"/>

//javascript

<script type="text/javascript">

function SaveWithParameter(parameter) {

__doPostBack('btnDelete', parameter)

}

</script>

//cs

if (Request["__EVENTARGUMENT"] != null && Request["__EVENTTARGET"] != null)

{

string parameter = Request["__EVENTARGUMENT"]; // parameter

string target = Request["__EVENTTARGET"]; // btnSave

if (target == "btnDelete")

{

SqlDataSourceAdress.DeleteParameters["AdressId"].DefaultValue = parameter;

SqlDataSourceAdress.Delete();

}
