从asp控件检索值在后面的c＃代码

我已经广泛地寻找这个问题的答案，但我只得到非常接近。我有一个用于添加和编辑记录的Web表单。当在gridview中选择一条记录时，会设置一个会话变量，然后在页面加载时使用它来填充文本字段。如果未设置会话变量，则表单将为空，逻辑将作为新记录运行。我的问题是，我可以成功添加一条新记录 - 我调试并检查以确保asp控件将正确的值传递给后面的代码 - 但我无法成功编辑记录。出于某种原因，文件后面的代码不会从文本框中检索正确的值。相反，它会保留原始的填充值，从而破坏编辑的目的。我认为这是一个具有约束力的问题，但我不确定，并已搜查结束。这里是我的隐藏文件代码：从asp控件检索值在后面的c＃代码

protected void Page_Load(object sender, EventArgs e) 
{ 
    resultOutput.Visible = false;//Output results as to whether or not a record was added successfully is automatically hidden at page load 

    //Checking to see if session variable has been created 
    if (Session["editID"] != null) 
    {    
     //Create objects to get recipe data 
     dbCRUD db = new dbCRUD(); 
     Recipe editRecipe = new Recipe(); 

     //Grabbing session ID 
     var id = Convert.ToInt32(Session["editID"]); 

     //Call method to retrieve db data 
     editRecipe = db.SelectRecord(id); 

     //Populate results to text boxes 
     recordID.Text = editRecipe.Recipe_ID.ToString(); 
     addName.Text = editRecipe.Name; 
     addTypeDDL.SelectedValue = editRecipe.Meal; 
     addDifficultyDDL.SelectedValue = editRecipe.Difficulty; 
     addCookTime.Text = editRecipe.Cook_Time.ToString(); 
     addDirections.Text = editRecipe.Directions; 

     //Change Button Text 
     submitRecord.Text = "Edit Record"; 

     //Change Title Text 
     addEditTitle.Text = "Edit Recipe"; 

    } 
} 

protected void submitRecord_Click(object sender, EventArgs e) 
{ 
    Recipe recipe = new Recipe(); 
    dbCRUD newRecord = new dbCRUD(); 

    //Variables for execution results 
    var modified = ""; 
    int returned = 0; 

    //Creating the recipe Object to pull the values from the form and 
    //send the recipe object as a parameter to the method containing insert stored procedure 
    //depending on Add or Edit 
    //recipe.Recipe_ID = int.Parse(recordID.Text); 
    recipe.Name = addName.Text.ToString(); 
    recipe.Meal = addTypeDDL.SelectedValue.ToString(); 
    recipe.Difficulty = addDifficultyDDL.SelectedValue.ToString(); 
    recipe.Cook_Time = int.Parse(addCookTime.Text); 
    recipe.Directions = addDirections.Text.ToString(); 


    //Checking to see if the page is loaded for edit or new addition 
    if (Session["editID"] != null) 
    { 
     recipe.Recipe_ID = Convert.ToInt32(Session["editID"]); 
     //If recordID exists, recipe will be passed to UpdateRecord method 
     returned = newRecord.UpdateRecord(recipe); 
     modified = "has been edited."; 
     Session.Remove("editID"); 
    } 
    else 
    { 
     //If recordID does not exist, record will be passed to InsertRecord method (new recipe) 
     returned = newRecord.InsertRecord(recipe); 
     modified = "added"; 
    } 

    //Method returns 0 if successful, 1 if sql error, 2 if other error 
    if (returned == 1) 
    { 
     resultOutput.Text = "There was an sql exception"; 
     resultOutput.Visible = true; 
    } 
    else if (returned == 2) 
    { 
     resultOutput.Text = "There was a non sql exception"; 
     resultOutput.Visible = true; 
    } 
    else 
    { 
     resultOutput.Text = "\"" + addName.Text + "\" recipe " + modified; 
     resultOutput.Visible = true; 
    } 
}

传递给我的编辑方法的对象是成功的，但是，正如我所说，它不会抢新更新的文本框中的值。

那么，是'db.SelectRecord（id）;'在页面重新加载时调用？ – Jodrell
