本文详细介绍了如何在GridView的编辑状态下，针对特定行的控件进行操作限制，包括跳转链接和按钮功能的调整。

GridView在Edit状态的行是Template中的EditItemtemplat中的控件，

某些时候，需要控制这些行，避免对他们进行操作

情况一：如不加!=EditIndex的控制，则RowDataBound将寻找空间HyperLink，而在Edit状态，控件无效

Code
<asp:TemplateField HeaderText="功能组名称">
<ItemTemplate>
<asp:HyperLink ID="Group_Name_Lab" runat="server"
Text='<%#Eval("Function_GroupName") %>'></asp:HyperLink>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
<EditItemTemplate>
<asp:TextBox ID="Group_Name_Box" runat="server"
Text='<%#Eval("Function_GroupName") %>'></asp:TextBox>
</EditItemTemplate>
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
</asp:TemplateField>

处理

Code
1

protected void FunctionGroupGridView_RowDataBound(
2

object sender, GridViewRowEventArgs e)
3

{
4

if (e.Row.RowIndex != -1 &&
5

e.Row.RowType == DataControlRowType.DataRow
6

&&e.Row.RowIndex!=this.FunctionGroupGridView.EditIndex)
7

{
8

((HyperLink)(e.Row.FindControl("Group_Name_Lab"))).NavigateUrl
9

=
10

"~/AdminManage/w_Function_QueryGroup.aspx?GID="
11

+ ((Label)(e.Row.FindControl("Group_ID_Lab"))).Text;
12

}
13

}

情况二：如不在EditItemtemplate中写一个相同的HyperLink，则RowDataBound失败，因为无法找到控件

Code
1

<asp:TemplateField HeaderText="操作">
2

<EditItemTemplate>
3

<asp:HyperLink ID="Img_Link" runat="server" Target="_blank"
4

Text="察看图片">
5

</asp:HyperLink>
6

|
7

<asp:LinkButton ID="LinkButton1" runat="server"
8

CausesValidation="True" CommandName="Update"
9

Text="更新">
10

</asp:LinkButton>
11

<asp:LinkButton ID="LinkButton2" runat="server"
12

CausesValidation="False" CommandName="Cancel"
13

Text="取消">
14

</asp:LinkButton>
15

</EditItemTemplate>
16

<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
17

<ItemTemplate>
18

<asp:HyperLink ID="Img_Link" runat="server" Target="_blank"
19

Text="察看图片">
20

</asp:HyperLink>
21

|
22

<asp:LinkButton ID="LinkButton1" runat="server"
23

CausesValidation="False" CommandName="Edit"
24

Text="编辑"></asp:LinkButton>
25

|
26

<asp:LinkButton ID="LinkButton2" runat="server"
27

CausesValidation="False" CommandName="Delete"
28

Text="删除" OnClientClick="ConfirmDel()">
29

</asp:LinkButton>
30

</ItemTemplate>
31

<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
32

</asp:TemplateField>

处理：

Code
protected void ImgGridView_RowDataBound(
object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex != -1 && e.Row.RowType ==
DataControlRowType.DataRow)
{
string A = ((Label)(e.Row.FindControl("Time_Lab"))).Text;
string B = ((Label)(e.Row.FindControl("Name_Lab"))).Text;
HyperLink HL = (HyperLink)(e.Row.FindControl("Img_Link"));
HL.NavigateUrl =
Config.getOtherPhotoFolder(Convert.ToDateTime(A)) + B;
}
}
