插入基于查询字符串 [英] Inserting On the basis of query string

问题描述

在我的项目中，我有两个页面首先我在网格中绑定数据，第二个我想插入数据，所以我在第一页中为它创建了一个查询字符串，但是当我在第二页中传递该查询字符串时显示 System.FormatException：输入字符串的格式不正确。 exception

我的代码为

In my project i have two pages In first i have bind data in grid and in second i want to insert data so i have made a query string for it in first page but when i am passing that query string in second page it shows System.FormatException: Input string was not in a correct format. exception
My code is as

  if (e.CommandName == "AddMasterData")
        {
            Response.Redirect("SubMasterData.aspx?ValueTypeID=" + Convert.ToString(e.CommandArgument) + "?mode=Add");
        }

and on second page 
 TenderManagement.Model.ValueType masterdata = new TenderManagement.Model.ValueType();
        masterdata.ValueTypeID = Convert.ToDecimal(Request.QueryString["ValueTypeID"]);
        masterdata.ValueTypeName = Convert.ToString(txtSubMasterData.Text.Trim());

任何人都可以帮忙!!

谢谢事先：）

can anyone help !!
thanks in advance :)

推荐答案

是e.CommandArgument一个十进制？

我不确定，但在Convert.ToString之后（e .CommandArgument）你做 +？mode = Add我认为它应该是 +& mode = Add



希望这会有所帮助。

is e.CommandArgument a Decimal?
I''m not sure, but after Convert.ToString(e.CommandArgument) you do + "?mode=Add" I think it should be + "&mode=Add"

hope this helps.

hi pandey，

首先修改请求，如下所示。 ..

Response.Redirect（SubMasterData.aspx？ValueTypeID =+ Convert.ToString（e.CommandArgument）+&mode = Add）;



masterdata.ValueTypeID = Convert.ToDecimal（Request.QueryString [ValueTypeID]）;



该字符串应仅包含数字，可以转换到十进制。

如果它包含任何字母，则无法解析为十进制。否则U应该将valuetypeid的数据类型更改为string。

hi pandey,
first modify the request like below...
Response.Redirect("SubMasterData.aspx?ValueTypeID=" + Convert.ToString(e.CommandArgument) + "&mode=Add");

masterdata.ValueTypeID = Convert.ToDecimal(Request.QueryString["ValueTypeID"]);

The string should contains only numbers,it is possible convert into decimal.
If it contains any letters it cannot parse to decimal. Otherwise U should change the datatype of the valuetypeid to string.
