使控件在gridview asp.net页中可见 [英] making control visible in gridview asp.net page

问题描述

我在gridview中有一个控件，该控件在设计中使visible = false，我在项目模板中添加了该控件.并在grdview_RowEditing事件中使该控件可见为真，

Hi,

i have a control in gridview which i have made visible=false in design,i have added that control in item template. and in grdview_RowEditing event i want to make that control visible true,

protected void grdview_RowEditing(object sender, grdviewEventArgs e)
        {
            try
            {
                if(text!="")
                {
                    ImageButton imgbtnexm5 =(ImageButton)grdview.Rows[e.NewEditIndex].FindControl("imgbtnexm5");
                    imgbtnexm5.Visible = true;
                }
}
}

但该控件不可见，
注意:我已在项目模板中添加了控件，并试图在编辑事件中使可见性为真，并且我尝试将其添加到编辑模板中，但我根本找不到控件.可能是因为该行尚未被编辑.

问:如何使该控件在RowEditing事件中可见，以及应在哪个模板中添加该控件.

but that control is not visible,
Note:i have added the control in item template,and trying to make the visibility true in edit event,and also i tried adding it in edit template but i wont find the control at all.may be because the row is not yet edited.

Q:how do i make the control visible in RowEditing event,and which template should i add the control.

<itemtemplate>
                                        <asp:Label ID="lblDate" runat="server" Text='<%# Bind("Date") %>'>
                                        <asp:ImageButton ID="imgbtnexm5" runat="server" ImageUrl="~/images/myimage.gif" Visible="false"/>
                                    </itemtemplate>

在此先感谢.

thanks in advance.

推荐答案

更好您将在Edit模板中拥有该控件，该控件将在编辑状态下自动显示.

Hi,

Better You would have the control in Edit template, that would be visible automatically in edit status .

<asp:TemplateField HeaderText="Name" SortExpression="FirstName">
            <EditItemTemplate>
                <asp:TextBox ID="TextBox1" runat="server"

                    Text='<%# Bind("FirstName") %>'></asp:TextBox>
            </EditItemTemplate>
            <ItemTemplate>
                <asp:Label ID="Label1" runat="server"

                    Text='<%# Bind("FirstName") %>'></asp:Label>
                <asp:Label ID="Label2" runat="server"

                    Text='<%# Eval("LastName") %>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>

我将代码粘贴到其他系统中了，

还是谢谢
