C# 当单击linkbutton时，如果这两个控件都是gridview的子控件，如何隐藏textbox控件？

我有一个网格视图，如下所示

<asp:GridView ID="dgTask" runat="server" Width="100%" 
            AutoGenerateColumns="False" onrowdatabound="dgTask_RowDataBound">
            <Columns>
                <asp:BoundField DataField="TaskID" HeaderText="TaskID" ItemStyle-Width="1%" />
                <asp:BoundField DataField="TaskName" HeaderText="Task Name" ItemStyle-HorizontalAlign="left"
                    ItemStyle-Width="10%" />
                <asp:BoundField DataField="PriorityName" HeaderText="Priority" ItemStyle-HorizontalAlign="center"
                    ItemStyle-Width="10%" />
                <asp:BoundField DataField="StatusName" HeaderText="Status" ItemStyle-HorizontalAlign="center"
                    ItemStyle-Width="10%" />
                <asp:TemplateField HeaderText="Edit Task" ItemStyle-Width="10%">
                    <ItemTemplate>
                        <asp:LinkButton ID="lnkBtnEdit" runat="Server" Text="Edit" CommandArgument ='<%# Eval("TaskID") %>' /> 
                        <asp:TextBox ID="txtId" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

谢谢

您的思路是正确的，只需在调用javascript函数时做一些小的更改，并添加javascript函数，如下所示

protected void dgTask_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton btnEdit = (LinkButton)e.Row.Cells[4].FindControl("lnkBtnEdit");
            TextBox txtId = (TextBox)e.Row.Cells[4].FindControl("txtId");
            btnEdit.Attributes.Add("onclick", "return Test("'" + txtId.ClientId + "'");");
        }
    }

然后像这样添加Javascript

function Test(var txtId)
{
    var inputtxt = document.getElementById(txtId);
    if(inputtxt != null)
    {
        inputtxt.Attributes.Add("style","display:none;");
    }

}

    }

}

试试这个：

protected void LinkButton1_Click(object sender, EventArgs e)
    {
        LinkButton b = (LinkButton)sender;
        GridViewRow r = (GridViewRow)b.NamingContainer;
        ((TextBox)(GridView1.Rows[r.RowIndex].Cells[0].FindControl("TextBox1"))).Visible = false;
    }

试试这个：

protected void LinkButton1_Click(object sender, EventArgs e)
    {
        LinkButton b = (LinkButton)sender;
        GridViewRow r = (GridViewRow)b.NamingContainer;
        ((TextBox)(GridView1.Rows[r.RowIndex].Cells[0].FindControl("TextBox1"))).Visible = false;
    }
