RadButton - 單點擊的方式，而不是radgrid控件的EditItemTemplate中

Question

內工作

有一個RadGrid其內部存在 EditItemTemplate一個RadComboBox和asp Button。

下面是當前的代碼：

<telerik:GridTemplateColumn UniqueName="AccountCode" HeaderText="Account Code"> 
    <ItemTemplate> 
     <asp:Label ID="lblAcCode" runat="server" Text='<%# Eval("AccountCode")%>'></asp:Label> 
    </ItemTemplate> 
    <EditItemTemplate> 

     <telerik:RadComboBox ID="ddlAccountCode" runat="server" Height="200" Width="240" DropDownWidth="310"  
     EnableLoadOnDemand="True" OnItemsRequested="ddlAccountCode_ItemsRequested" EnableItemCaching="true" 
     ShowMoreResultsBox="True" EnableVirtualScrolling="true" AllowCustomText="true" MarkFirstMatch="true" 
     Filter="Contains" HighlightTemplatedItems="true" CausesValidation="true" AppendDataBoundItems="true" 
     DataTextField="AccountDescription" DataValueField="AccountCodeID" 
     ShowDropDownOnTextboxClick="false" 
     OnClientDropDownOpening="OnClientDropDownOpening" OnClientItemsRequested="OnClientItemsRequested" 
     OnClientTextChange="LoadECnEntityKeys" /> 

     <asp:Button ID="btnSearch" runat="server" Text="Search" OnClient="btnSearch_Click" /> 
     &nbsp; 
     <asp:Label ID="lblMsg" runat="server" Visible="false"></asp:Label> 

    </EditItemTemplate> 
</telerik:GridTemplateColumn> 

protected void btnSearch_Click(object sender, EventArgs e) 
{ 
    Response.Write("Default.aspx"); 
    //other code 
} 

當我鍵入內部RadComboBox東西鍵入/，點擊asp Button， 則只有OnClick執行後，有關鍵入的文本啓動和顯示搜索事件asp Button。

現在，新的要求來到了RadButton（帶 - 單擊 的方法），以取代asp Button，以避免雙擊。

問題是：當我實現RadButton內radgrid控件的EditItemTemplate，RadButton從來沒有回傳，即，當我點擊它沒有任何反應。 但是當我在RadGrid以外使用RadButton時，工作正常。

下面是使用代碼RadButton（帶 - 單點擊 方法）：

<telerik:GridTemplateColumn UniqueName="AccountCode" HeaderText="Account Code"> 
    <ItemTemplate> 
     <asp:Label ID="lblAcCode" runat="server" Text='<%# Eval("AccountCode")%>'></asp:Label> 
    </ItemTemplate> 
    <EditItemTemplate> 

     <telerik:RadComboBox ID="ddlAccountCode" runat="server" Height="200" Width="240" DropDownWidth="310"  
     EnableLoadOnDemand="True" OnItemsRequested="ddlAccountCode_ItemsRequested" EnableItemCaching="true" 
     ShowMoreResultsBox="True" EnableVirtualScrolling="true" AllowCustomText="true" MarkFirstMatch="true" 
     Filter="Contains" HighlightTemplatedItems="true" CausesValidation="true" AppendDataBoundItems="true" 
     DataTextField="AccountDescription" DataValueField="AccountCodeID" 
     ShowDropDownOnTextboxClick="false" 
     OnClientDropDownOpening="OnClientDropDownOpening" OnClientItemsRequested="OnClientItemsRequested" 
     OnClientTextChange="LoadECnEntityKeys" /> 

     <telerik:RadButton runat="server" ID="btnSearch" Text="Search" SingleClick="true" 
     SingleClickText="Submitting..." OnClick="btnSearch_Click" /> 
     &nbsp; 
     <asp:Label ID="lblMsg" runat="server" Visible="false"></asp:Label> 

    </EditItemTemplate> 
</telerik:GridTemplateColumn> 

protected void btnSearch_Click(object sender, EventArgs e) 
{ 
    Response.Write("Default.aspx"); 
    //other code 
} 

請讓我知道這是爲什麼hapenning？ 請不要回復

在此先感謝

我會建議你使用的CommandName作爲按鈕的事件。無論如何，這裏是我的代碼...我嘗試使用OnClick和CommandName它工作得很好。我懷疑你的錯誤將是某種形式的javascript ...

的.aspx

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" Width="100%" 
OnNeedDataSource="RadGrid1_NeedDataSource" OnItemCommand="RadGrid1_ItemCommand"

<MasterTableView EditMode="InPlace"> 
    <Columns> 
     <telerik:GridTemplateColumn> 
      <ItemTemplate> 
       <asp:Label ID="lblAcCode" runat="server" Text='<%# Eval("T")%>'></asp:Label> 
      </ItemTemplate> 
      <EditItemTemplate> 
       <telerik:RadComboBox ID="rcb" runat="server" AllowCustomText="true">
