按钮字段在转换为模板字段时不执行

本文关键字：字段 执行 转换 按钮 | 更新日期: 2023-09-27 18:15:28

你好，我有这个按钮字段在一个网格视图执行以下功能。

但是如果我将这个按钮字段转换为模板字段，函数不会执行。

错误是得到{"Input string was not in a correct format."}.

<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>

按钮字段在转换为模板字段时不执行

@Hakunamatata在评论部分提到，<ItemTemplate>下的链接按钮没有设置CommandArgument

然而，根据您的代码，如果您只是在触发链接按钮单击的相应行的行索引之后，那么您可以这样做。

    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);
        }
    }

基本上我把

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


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