出现ModalPopupControl，而无需单击targetControl [英] ModalPopupControl appears without me clicking on targetControl

问题描述

嗨
我在弹出窗口时遇到麻烦，它似乎出现在我在表单上执行的任何活动中，我有一个文本框，该文本框使用textchanged事件来检索并在弹出面板上显示数据，但是该弹出窗口应该仅在我单击一个按钮，但是当我在文本框中更改文本时似乎出现了

Hi
I''m having trouble with my popup it seems to appear on any activity I do on the form, i have a textbox that uses the textchanged event to retrieve and show data on the popup panel but the popup is suppose to appear only when I click on a button but it seems to appear when I change text on the textbox

<asp:TextBox ID="txtProdId" runat="server" 
    ontextchanged="txtProdId_TextChanged" ></asp:TextBox>
<asp:AutoCompleteExtender ID="txtProdId_AutoCompleteExtender" runat="server"      completioninterval="10" enablecaching="true" inimumprefixlength="1" DelimiterCharacters="" Enabled="True" servicemethod="GetProductIDlist" ServicePath="~/WebService1.asmx" TargetControlID="txtProdId">
</asp:AutoCompleteExtender>


 <asp:Button ID="btnAddQProd" runat="server" BorderStyle="Outset" 
   Font-Bold="True" Text="Add Product" />
 <asp:ModalPopupExtender ID="btnAddQProd_ModalPopupExtender" runat="server" 
   DynamicServicePath="" Enabled="True" TargetControlID="btnAddQProd" PopupControlID="Panel1"
   DropShadow="true" OkControlID="btnAdd" OnOkScript="btnAdd_Click" CancelControlID="btnCancel"
   BackgroundCssClass="modalBackground">
 </asp:ModalPopupExtender>

这是文本框事件，它使用适当的值填充弹出面板中的控件

and this is the textbox event that populates the controls in the popup panel with appropriate values

protected void txtProdId_TextChanged(object sender, EventArgs e)
       {
           BusinessLogicLayer.Product objex = new BusinessLogicLayer.Product();
           objex.propProdId = txtProdId.Text;
           BusinessLogicLayer.Product P = objex.GetProduct();
           this.txtProdId.Text = P.propProdId;
           this.txtProdDesc.Text = P.propProdDesc;
           this.txtFinish.Text = Convert.ToString(P.propFinishPrice);
           this.txtPrice.Text = Convert.ToString(P.propUnitPrice);
           this.txtQty.Text = Convert.ToString(P.propQty);
           this.lblProdIDmod.Text = P.propProdId;

       }

此处是面板代码

here''s The panel code

<asp:updatepanel id="UpdatePanel2" runat="server" updatemode="Conditional" xmlns:asp="#unknown">
