问题描述
我有Gridveiw有7列，其中3列是下拉列表
我的要求 - >我需要在更新行或添加新行之前验证这3列。
如果选择第一列（测试/窗口），所有3列都是相互关联的frame）在第二列（测试对象）中填充值并基于第二列填充第3列（测试对象），但现在问题是在填充所有列（即所有3列）后用户可以去返回并将第二列更改回--Select--并且可以更新我需要防止这种情况发生，所以我如何验证所有列。
以下是代码
Hi, I have Gridveiw which has 7 Columns and out of that 3 columns are drop down list
My Requirement--> I need to validate this 3 Columns before updating the row or during adding the new rows.
All the 3 columns are interrelated if you select the first column(Test/window frame) the values get populated in the second column(Test Object)and based on the second column the 3rd column(Test Object) gets populated , but now the problem is after populating all the columns(i.e all the 3 columns) user can go back and change the 2nd column back to "--Select--" and can update I need to prevent this from happening so how do i validate all the columns.
Below is the code
