Question

我使用这个:http://www.asp.net/ajaxlibrary/Ajax ControlToolkitSampleSite/MaskedEdit/MaskedEdit.aspx

In a column I have multiple textboxes binded to some columns from database. My goal is to get the value from those textboxes that are maskedit. Since there are 4 controls in the column I m trying to get the values like this:

String firstTXT = ((TextBox)(row.Cells[5].Controls[1])).Text;
String SecondTXT = ((TextBox)(row.Cells[5].Controls[2])).Text;

I can get the value from the firsttexbox without any error ( but it s also masked ) . and when I Try to get from the second I get : Unable to cast object of type AjaxControlToolkit.MaskedEditExtender to type System.Web.UI.WebControls.TextBox .

有解决的机会吗? 谢谢。

显然,单元格中的第三个控件是 MaskedEditExtender ,该控件将增强第一个文本框。根据您的标记,您可能想要取而代之的是第四个控件:

string secondTXT = ((TextBox) row.Cells[5].Controls[3]).Text;

或者,最好把id 属性赋予您的文本框,并使用 < a href="http://msdn.microsoft.com/en-us/library/486wc64h.aspx" rel=“nofollow” >Find control( )来获取它们:

string firstTXT = ((TextBox) row.Cells[5].FindControl("firstID")).Text;
string secondTXT = ((TextBox) row.Cells[5].FindControl("secondID")).Text;
