如何在网格视图代码隐藏中应用我的静态方法？ [英] How can I apply my static method in grid view codebehind?

问题描述

所以这就是我想对DataTextFormatString做的事情，我想将其格式化为加密但是唯一被加密的是{0}而不是它所代表的实际行，请帮忙。 />


我尝试了什么：



这是我试过的东西，但我知道它的语法错误。但是我希望你能理解我想要做的事情......

So here is what I am trying to do on DataTextFormatString, I want to format it to encrypted but the only thing that is being encrypted is "{0}" and not the actual rows that it represents, please help.

What I have tried:

This the things that I have tried, but I know it has the wrong syntax. But I hope you get the idea on what I am trying to do...

HyperLinkField Age = new HyperLinkField();
Age.DataNavigateUrlFormatString = "./testpage.aspx?Id={0}";
Age.DataTextField = "Age";
Age.HeaderText = "Age";
Age.DataTextFormatString = Encryption.GetEncryption("{0}");
GridView1.Columns.Add(Age);

加密有静态方法GetEncryption就是这样：

Encryption has the static method GetEncryption which is this:

public static string GetEncryption(string data)
    {
        return Convert.ToBase64String(EncryptString(data));
    }

推荐答案

所以，我按照你的建议，这是我对我的问题的回答，



我在数据集中添加了一个新列，名为'encrypted_age'，



然后在数据表上我处理了从列时代开始的现有行，以进行加密。我使用if行是空的，因为我不需要数据集上的新行，而是用新的行值填充新列。



列之后'Encrpyted_Age'已填充，我用它显示在GridView列后面的代码，即HyperLinkField。



感谢您帮助我

So, I followed your advise and this is my answer to my question,

I added a new column to the data set, named 'encrypted_age',

Then on the data table I processed the existing rows from column age, to be encrypted. I used the if rows is empty since I don't need a new row on the data set but to fill the new column with new row values.

After the column 'Encrpyted_Age' is filled, I used it to be displayed on the code behind GridView Column which is the HyperLinkField.

Thank you for helping me

ds.Tables[0].Columns.Add("Encrypted_Age", typeof(string));
           int i = 0;
           foreach (DataRow row in ds.Tables[0].Rows)
           {

               if (ds.Tables[0].Rows[i][3].ToString() == "")
               {
                   ds.Tables[0].Rows[i][3] = Crypto.GetEncryptedQueryString(row["age"].ToString());
               }
               i++;
           }

           ds.Tables[0].AcceptChanges();

           con.Close();

           HyperLinkField Age = new HyperLinkField();
           string[] dataNavigateUrlFields = { "Encrypted_Age" };

           Age.DataNavigateUrlFormatString = "./testpage.aspx?id={0}";
           Age.DataNavigateUrlFields = dataNavigateUrlFields;
           Age.DataTextField = "Encrypted_Age";
           Age.HeaderText = "Age";

           GridView1.Columns.Add(Age);

           GridView1.DataSource = ds;
           GridView1.DataBind();
