How to get value of cell in a variable

my vb coading is given below

Protected Sub gvShape_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvShape.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then
            For c As Integer = 0 To gvShape.Columns.Count - 1
                Dim shapeid As String = CType(e.Row.Cells(c).FindControl("lbl_col_" & c + 1), Label).Text
                e.Row.Cells(c).Attributes.Add("onDblClick", String.Format("popup('{0}')", shapeid))
                e.Row.Cells(c).Attributes.Add("onClick", String.Format("select({0},{1},'{2}')", e.Row.RowIndex, c, shapeid))

            Next
        End If
    End Sub

推荐答案

您首先要找出 System.Web.UI.WebControls.GridViewRowEventArgs [ ^ ]最好是通过谷歌搜索来实现.在该页面上，您会发现此事件参数具有行 [ ^ ]属性.此Row属性的类型为 GridViewRow [ ^ ]其中您会找到 Cells [ [ ^ ].

我们快到了，等等.现在，这取决于表单元格的内容.表格单元格可以包含相当多的 view 内容，其中之一是文本，因此访问此属性称为控件 [ ^ ]属性即可访问这些属性.

最好的选择是调试应用程序，并查看网格视图中包含的实时数据.

最好的问候，

You start by finding out what System.Web.UI.WebControls.GridViewRowEventArgs[^] is preferably by googling for it. On that page you''ll find that this event argument has a Row[^] property. This Row property is of type GridViewRow[^] where you find the Cells[^] indexed property. This yields a TableCellCollection and one of the contained items is a TableCell[^].

We''re almost there, hold on. Now it depends what the content of your table cell is. There are quite a view few things a table cell can contain and one of them is text and thus the property to access this is called Text[^]. It might be as well that this TableCell contains other controls then you''d have to use the Controls[^] property to access those.

Your best bet would be to debugg your application and have a look at the live data contained in your grid view.
