编辑后得到一个gridview列标题

Question

我正在使用一个ASP.net项目，并有一个从sql数据库的数据集作为数据源的gridview。

当我更改gridview中的值时，我想更新数据集，以便我可以使用该数据集再次更新数据库。

到目前为止我的说法。

这是我遇到麻烦的部分。我可以获取选定的行，但不能选择列名来更新数据集。

myDataSet.Tables[0].Rows[e.RowIndex][?] = ""; 

RowUpdating事件的完整代码。

protected void grdViewDetails_RowUpdating(object sender, GridViewUpdateEventArgs e) 
     { 
       //Just get the dataset populated from my database (sql) 
       DataSet dsOriginal = dbConn.returnSqlDataset(query); 

       //update the dataset here so that you can update the database again. 
       foreach (TableCell cell in grdViewDetails.Rows[e.RowIndex].Cells) 
       { 
        //set the employeeid so you can update the dataset 
        if (cell.Controls[0] is TextBox) 
        { 
         TextBox textbox = (TextBox)cell.Controls[0]; 
         string value = textbox.Text; //This is just a tester to see if the value is correct 
        // dsOriginal.Tables[0].Rows[e.RowIndex][?] = value; //Here is the problem, how to get the selected column name 

        } 
        else 
        { 
         if (cell.Controls[0] is CheckBox) 
         { 
          CheckBox chkBoxWeek = (CheckBox)cell.Controls[0]; 
          Boolean checkStatus = chkBoxWeek.Checked; //This is just a tester to see if the value is correct 
          //dsOriginal.Tables[0].Rows[e.RowIndex][?] = checkStatus; //Here is the problem, how to get the selected column name 
         } 
        } 
       } 

       //Use the updated dataset to update the database with. 
       dbConn.udpatCourse(dsOriginal); 


      } 

Answer 1

您可以遍历GridViewUpdateEventArgs.NewValues集合来找出已更新的内容。

这稍微改编自联MSDN文档：

foreach (DictionaryEntry entry in e.NewValues) 
{ 
    string columName = entry.Key; 
    string userInput = e.NewValues[entry.Key]; 
    // Now you can do stuff with this info that meets your logic needs 
} 

如果我正确地读你的问题，你应该能够让你从这里所需要的。
