Question

你好我在网格视图中有这个按钮字段，它执行以下功能。

但如果我将此按钮字段转换为模板字段，则该函数不会执行。

我得到的错误{＆＃34;输入字符串的格式不正确。＆＃34;}。

<asp:ButtonField CommandName="Selectagreement" HeaderText="Select" ControlStyle-CssClass="btn btn-primary" Text="select">
                            <ControlStyle CssClass="btn btn-primary" />
                        </asp:ButtonField>
        protected void gvAgreement_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        try
        {
            string commandName = e.CommandName.ToString().Trim();
            GridViewRow row = gvAgreement.Rows[Convert.ToInt32(e.CommandArgument)];
            switch (commandName)
            {
                case "Selectagreement":
                    Label1.Text = row.Cells[2].Text;
                    break;
                default: break;

            }
        }
        catch (Exception ex)
        {
            Response.Write("Error: " + ex.Message);

        }
    }



                         <asp:TemplateField HeaderText="Select" ShowHeader="False">
                            <ItemTemplate>
                                <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="false" CommandName="Selectagreement" Text="select"></asp:LinkButton>
                            </ItemTemplate>
                            <ControlStyle CssClass="btn btn-primary" />
                        </asp:TemplateField>

如@Hakunamatata在评论部分所述，CommandArgument未设置为<ItemTemplate>下的链接按钮。

但是，如果您刚刚在触发链接按钮的相应行的行索引之后单击您的代码，则可以执行此操作。

    protected void gvAgreement_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        try
        {
            string commandName = e.CommandName.ToString().Trim();

            GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);

            switch (commandName)
            {
                case "Selectagreement":
                    Label1.Text = row.Cells[2].Text;
                    break;
                default: break;

            }
        }
        catch (Exception ex)
        {
            Response.Write("Error: " + ex.Message);

        }
    }

基本上我换了

    GridViewRow row = gvAgreement.Rows[Convert.ToInt32(e.CommandArgument)];

与

    GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);

将字段转换为模板字段时，按钮字段不会执行
