requiredfieldvalidator not working inside updatepanel

Question

0.00/5 (No votes)

See more:

I am creating the new row inside the grid view from external button present outside the grid view with dynamically creating the dropdownlist and validating it. It used to work fine until I have moved the grid view inside the update panel.

Is there any way to validate the dropdownlist inside the UpdatePanel?

Here's my code so far:

C#

DropDownList ddlEmployeeName1 = new DropDownList();

ddlEmployeeName1.ID = "ddlEmployeeName1";
ddlEmployeeName1.Attributes.Add("runat", "server");
ddlEmployeeName1.Width = 200;
ddlEmployeeName1.ValidationGroup = "valSave";
ddlEmployeeName1.CausesValidation = true;
DropDownList ddlEmployeeRole = new DropDownList();
ddlEmployeeRole.ID = "ddlEmployeeRole";

ddlEmployeeRole.Attributes.Add("runat", "server");

if (!generic.isRowDataSaved)
{
    // e.Row.Cells[1].Controls.Add(lblEmployeeCode);
    e.Row.Cells[2].Controls.Add(ddlEmployeeName1);
    e.Row.Cells[3].Controls.Add(ddlEmployeeRole);   //textbox is added as last column of grid
    List<employeebo> employeeList = new List<employeebo>();
    EmployeeService employeeService = new EmployeeService(this.ContextBO);

    lblPoNumberIns1.Text = "PO12345";
    ddlEmployeeName1.EnableViewState = true;
    ddlEmployeeName1.AppendDataBoundItems = true;
    ddlEmployeeName1.AutoPostBack = true;
    employeeList = employeeService.GetEmployeeList();//(List<employeebo>)Session[UIConstants.GetEmployeeList];
    ddlEmployeeName1.DataSource = employeeList;
    ddlEmployeeName1.Items.Add(new ListItem("Please Select EmployeeName", "0"));
    ddlEmployeeName1.Font.Size = FontUnit.XXSmall;
    ddlEmployeeName1.Width = 200;
    ddlEmployeeName1.CausesValidation = true;
    ddlEmployeeName1.DataTextField = "EmployeeName";
    ddlEmployeeName1.DataValueField = "EmployeeOrbitCode";
    ddlEmployeeName1.DataBind();
    ddlEmployeeName1.Attributes.Add("onChange", "return empOrbitCodeUpd(this," + e.Row.RowIndex + ");");
    RequiredFieldValidator nameValidator = new RequiredFieldValidator();
    if (ddlEmployeeName1.SelectedValue.ToString() == "0")
    {
        nameValidator.ControlToValidate = ddlEmployeeName1.UniqueID;
        nameValidator.Attributes.Add("runat", "server");

        nameValidator.ErrorMessage = "Please Select EmployeeName";
        nameValidator.Font.Size = FontUnit.XXSmall;
        nameValidator.ID = "nameValidator";
        nameValidator.Display = ValidatorDisplay.Dynamic;
        nameValidator.SetFocusOnError = true;
        nameValidator.ValidationGroup = "valSave";
        nameValidator.InitialValue = "0";
        nameValidator.Text = "*";

        this.Form.Controls.Add(nameValidator);
     }

If I understand your question right, you are validating on server side...Controls inside UpdatePanel will be excluded from postback if you do not declare UpdatePanel properties well...

@MukeshSagar, Thanks for the reply, can please elaborate your answer, where i can add the scriptmanager, i have already added the tooscript manager inside the master page.

MukeshSagar 6-Oct-14 7:21am

Before the UpdatePanel tag

santoshkumar413 6-Oct-14 8:19am

@Mukesh, I have added the script manager, but still validation doesnot works.

MukeshSagar 6-Oct-14 8:27am

Then send the code for aspx file and .cs file, then only i can check for the problem
