我可以在gridview单元格中有不同的视图吗？ [英] Can I have a different view in a gridview cell?

问题描述

在3列asp：GridView中，我需要第二列是基于第一列值的文本框，下拉列表或一系列数据（从x到y）。

有没有办法做到这一点？



我目前拥有的是一个独立的DropDownList。然后根据所选值激活MultiView。有三种视图可以激活。一个普通的TextBox，一个DropDownList，然后是2个文本框，一个From框和一个To框，表示一系列值。我想知道它是否可以在GridView中完成。

In a 3 column asp:GridView, I need the 2nd column to be either a textbox, a dropdownlist, or a range of data(a from x to y) based on the value of the first column.
Is there a way to do that?

What I currently have is a standalone DropDownList. Then based on the selected value, a MultiView is activated. There are three views that can be activated. A plain TextBox, a DropDownList, and then 2 textboxes a From box and a To box for a range of values. I would like to know if it can be done in a GridView.

推荐答案

你可以使用5列的gridview（其中第1和第3是固定的），第二个是/隐藏取决于第一个价值



您的gridview将如下所示：

1st

第2个a）文本框

第二个b）下拉菜单

第二个c）范围

第三个



然后在CellFormatting事件中，你检查第一列的值并适当地显示/隐藏第二列。



像这样（在CellFormatting事件中）：

You can have gridview with 5 columns (where 1st and 3rd are fixed) and second is shown / hidden depending on the value of the first

Your gridview would then look like this:
1st
2nd a) textbox
2nd b) dropdown
2nd c) range
3rd

Then in CellFormatting event you check the value of 1st column and show / hide 2nd appropriately.

Something like this (in CellFormatting event):

DataRowView drv = CType (dgv.Rows[e.RowIndex].DataBoundItem, DataRowView);
dgv.columns["2nda"].Visible = (drv["1st"] == value1);
dgv.columns["2ndb"].Visible = (drv["1st"] == value2);
dgv.columns["2ndc"].Visible = (drv["1st"] == value3);

e.FormattingApplied = True;
