在Gridview asp.net vb中按下编辑时，行未在编辑模式下打开 [英] Row not opening in edit mode on pressing edit in Gridview asp.net vb

问题描述

大家好，



我在Web应用程序中创建了一个数据绑定网格视图，并试图在每行的编辑按钮中编辑行。但是在按下编辑按钮时，行仍在修复并且不允许编辑。虽然出现了更新和取消按钮。



以下代码为vb

hi all,

I have created a databound grid view in a web application and trying to edit the rows throught each row's edit button. But on pressing the edit button the row is still fix and edit is not allowed. Though the Update and cancel button appears.

following is code in vb

Protected Sub DataGridView1_RowEditing(sender As Object, e As GridViewEditEventArgs) Handles DataGridView1.RowEditing
        DataGridView1.EditIndex = e.NewEditIndex
        Call fnShowBom()***(function to call data from sql and bind the grid)

    End Sub

提前致谢



gridview代码：

Hello ,

to get Gridview in Edit mode you have to use TemplateField .and you must use asp:TextBox in the EditItemTemplate instead of asp:Label . For more details
