gridview上的文本框条件 [英] textbox condition on gridview

问题描述

我在GridView中有一个用于标记条目的TextBox，我想检查条件，如果操作员输入大于满标记的标记，则显示错误信息。

我的网格视图那样





Sl。 No. StudentID RegistrationNo RollNo Full Marks输入标记



1 1 110001001 11000101 100 TextBox

2 2 110001002 11000102 100 TextBox

I have a TextBox in GridView for Marks Entry and I want to check condition that if operator enter Marks greater than full marks it display error message.
My GridView Like That


Sl. No. StudentID RegistrationNo RollNo Full Marks Enter Marks

1 1 110001001 11000101 100 TextBox
2 2 110001002 11000102 100 TextBox

推荐答案

尝试这样一个

Try like this one

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:CompareValidator ID="CompareValidator1" runat="server" ControlToValidate="TextBox1" ErrorMessage="Must be less than or equal to 100" Operator="LessThanEqual" Type="Integer" ValueToCompare="100" />

问候..：笑：

你告诉文本框在gridview内。

我希望操作员只在编辑模式下输入标记，并且只能在更新模式下进行检查。

所以你最好试试这样的

you told that the textbox is inside the gridview.
I hope the operator will enter the marks during edit mode only and check can be made during the update mode only.
So you better try like this

GridViewRow UpdateRow = gvMarkList.Rows[e.RowIndex];
TextBox txtEnteredMarks= (TextBox)UpdateRow.FindControl("txtMarks");

if (txtEnteredMarks.Text. > "100")
   {
          // Show your error
   }
else
   {
          // do your operation like update the data
   }

希望有帮助...
