Question

我的gridview中有一个编辑功能。但是我想要做的是当我点击特定数据绑定的更新功能时禁用文本框的可见性。这是我的aspx代码：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ProductID" 
OnPageIndexChanging="GridView1_PageIndexChanging" OnRowCancelingEdit="GridView1_RowCancelingEdit" 
OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" 
        OnRowUpdating="GridView1_RowUpdating">
<Columns>
    <asp:TemplateField HeaderText="ProductName">
        <ItemTemplate>
            <asp:Label ID="Label1" runat="server" Text='<%# Bind("ProductName") %>'></asp:Label>
        </ItemTemplate>
        <EditItemTemplate>
            <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("ProductName") %>'></asp:TextBox>
            <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
             ErrorMessage="Invalid" ForeColor="Red" ControlToValidate="txtboxProductName"
            ValidationExpression="^[a-zA-Z ]+$"></asp:RegularExpressionValidator>
        </EditItemTemplate>
    </asp:TemplateField>
    <asp:TemplateField HeaderText="ProductDescription">
        <ItemTemplate>
            <asp:Label ID="Label2" runat="server" Text='<%# Bind("ProductDescription") %>'></asp:Label>
        </ItemTemplate>
        <EditItemTemplate>
            <asp:TextBox ID="txtboxProductDescription" runat="server" Text='<%# Bind("ProductDescription") %>'></asp:TextBox>
            <asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server" ErrorMessage="Invalid" 
            ForeColor="Red" ControlToValidate="txtboxProductDescription"
            ValidationExpression="^[a-zA-Z ]+$"></asp:RegularExpressionValidator>
        </EditItemTemplate>
    </asp:TemplateField>
    <asp:ImageField HeaderText ="ProductImage" DataImageUrlField="ProductImage" SortExpression="ProductImage" ControlStyle-Width ="10">

        <ControlStyle Width="50px"></ControlStyle>

        </asp:ImageField>
    <asp:TemplateField HeaderText="ProductQuantity">
        <ItemTemplate>
            <asp:Label ID="Label3" runat="server" Text='<%# Bind("ProductQuantity") %>'></asp:Label>
        </ItemTemplate>
        <EditItemTemplate>
            <asp:TextBox ID="txtboxProductQuant" runat="server" Text='<%# Bind("ProductQuantity") %>'></asp:TextBox>
            <asp:RegularExpressionValidator ID="RegularExpressionValidator3" runat="server" ErrorMessage="Invalid" ControlToValidate="txtboxProductQuant"
            ForeColor="Red" ValidationExpression=^[0-9]*$></asp:RegularExpressionValidator>
        </EditItemTemplate>
    </asp:TemplateField>
    <asp:TemplateField HeaderText="ProductPrice">
        <ItemTemplate>
            <asp:Label ID="Label4" runat="server" Text='<%# Bind("ProductPrice") %>'></asp:Label>
        </ItemTemplate>
        <EditItemTemplate>
            <asp:TextBox ID="txtboxProductPrice" runat="server" Text='<%# Bind("ProductPrice") %>'></asp:TextBox>
            <asp:RegularExpressionValidator ID="RegularExpressionValidator4" runat="server" ErrorMessage="Invalid" ControlToValidate="txtboxProductPrice"
            ForeColor="Red" ValidationExpression=^[0-9]*$></asp:RegularExpressionValidator>
        </EditItemTemplate>
    </asp:TemplateField>
    <asp:CommandField ShowEditButton="true" />
    <%--<asp:CommandField ShowDeleteButton="true" />--%>
    <asp:TemplateField>
        <ItemTemplate>
        <asp:LinkButton ID="lnkdel" runat="server" Text="Delete" CommandName="Delete" 
        OnClientClick="return confirm('Confirm Delete?');"></asp:LinkButton>

        </ItemTemplate>
        <ItemStyle Width="100px" />

        </asp:TemplateField>
    </Columns>
</asp:GridView>

这是我的更新代码：

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        //Finding the controls from Gridview for the row which is going to update  
        //Label id = GridView1.Rows[e.RowIndex].FindControl("lbl_ID") as Label;
        int userid = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value.ToString());
        TextBox ProductName = GridView1.Rows[e.RowIndex].FindControl("txtboxProductName") as TextBox;
        TextBox ProductDescription = GridView1.Rows[e.RowIndex].FindControl("txtboxProductDescription") as TextBox;
        TextBox ProductQuantity = GridView1.Rows[e.RowIndex].FindControl("txtboxProductQuant") as TextBox;
        TextBox ProductPrice = GridView1.Rows[e.RowIndex].FindControl("txtboxProductPrice") as TextBox;
        conn = new SqlConnection("Data Source = 'PAULO'; Initial Catalog=Authorship;Integrated Security =True");
        conn.Open();
        //updating the record  
        SqlCommand cmd = new SqlCommand("Update Products set ProductName='" + ProductName.Text + "',ProductDescription='" + ProductDescription.Text + "',ProductQuantity='" + ProductQuantity.Text + "', ProductPrice='" + ProductPrice.Text + "' where ProductID='" + userid + "'", conn);
        cmd.ExecuteNonQuery();
        conn.Close();
        //Setting the EditIndex property to -1 to cancel the Edit mode in Gridview  
        GridView1.EditIndex = -1;
        //Call ShowData method for displaying updated data  
        gvbind(); 
}

我没有在编辑模板中包含产品图片，而且产品图片也不包含在我的代码中。无法理解为什么当我点击更新功能时文本框在产品图像上变得可见。请帮忙。

如果（e.Row.RowState和DataControlRowState.Edit）> 0然后

例如 Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs) Handles GridView1.RowDataBound If e.Row.RowState = DataControlRowState.Edit Then ctype(e.Row.Cells(1).Controls(0),TextBox).Enabled=False End If End Sub

在编辑模式下禁用文本框
