GridView RowUpdating 取欄位值 欄位名稱 CustomValidator 設定

2. 擷取 GridView內部的某一列、某一欄位的值

欄位值

 string d = (string)e.NewValues["LastName"];

string d = (string)e.NewValues["LastName"];

 if (d.Length < 5)

 {

 this.ClientScript.RegisterClientScriptBlock(this.GetType(), "msg", "");

 e.Cancel = true;

}

            else

            {

                this.ClientScript.RegisterClientScriptBlock(this.GetType(), "msg", "");

            }

欄位 input 名稱

GridView1.Rows[e.RowIndex].Cells[3].Controls[0].ClientID

--------------  CustomValidator  驗證 類別 使用  --------------

CustomValidator _CustomValidator = new CustomValidator(); 建立類別

_CustomValidator.ControlToValidate = this.txtName.ID; 控制名稱

_CustomValidator.ClientValidationFunction = "check"; Function 名稱

_CustomValidator.ErrorMessage = "請輸入資料"; 錯誤訊息文字

_CustomValidator.ValidateEmptyText = true; 是否驗證空白(一定要選)

_CustomValidator.EnableClientScript = true; 驗證使用者是否把Script 關閉

_CustomValidator.ServerValidate += new ServerValidateEventHandler(CustomValidator1_ServerValidate); 註冊 Code Server端驗證

Page.Form.Controls.Add(_CustomValidator); 將類別 放置Form 裡面

Code

        private void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)

        {

            if (txtName.Text.Length < 5)

            {

                this.ClientScript.RegisterClientScriptBlock(this.GetType(), "msg", "");

                args.IsValid = false;

            }

            else

                this.ClientScript.RegisterClientScriptBlock(this.GetType(), "msg", "");

        }

Html

scriptfunction check(source, arguments){

    if(arguments.Value.length<5){

        alert("長度要大於4");

        arguments.IsValid = false;

    }

    else{;

    }

}

script

2. 擷取 GridView內部的某一列、某一欄位的值

C#語法 -- TextBox my_test_time = (TextBox)GridView1.Rows[e.RowIndex].Cells[4].Controls[0];

VB語法 -- Dim my_test_time As TextBox = GridView1.Rows(e.RowIndex).Cells(4).Controls(0)

              或是用 CType(GridView1.Rows(e.RowIndex).Cells(4).Controls(0), TextBox)來作轉換，強制轉成TextBox型態
