Hello Experts,

I'm working on a project which is a kind of HRMS. I'm stuck with a problem with the Validators. In a page I've dynamically created & attached two validators , one is RangeValidator and the other one is RequiredFieldValidator to a TextBox control. The problem is When I pass "HR" for login and getting onto this page, both the validators work absolutely fine, but when I'm trying to use some other Department say-"abc" they get failed. Validation errors are being shown after the button click event code are executed. How can I restrict them to validate before the button_click event code get executed. please help me.

below is the method I use to set:

C#

public static void SetKPIs(DataTable dt, string dept, Panel pnl, Panel rfvpnl)
        {
            if (dt != null)
            {
                try
                {
                    DataRow[] EmpKPIs = dt.Select("dept='" + dept + "'");

                    foreach (DataRow dr in EmpKPIs)
                    {
                        Label lbl = new Label { ID = "lbl_" + dept + "_" + dr["kpi"].ToString(), Text = dr["kpi"].ToString() + " :", Width = new Unit(135) };
                        Label lblBlank = new Label { CssClass = "label", ID = "Min_Max_" + dept + "_" + dr["kpi"].ToString(), Text = "  (" + dr["kpi_min_weight"].ToString() + " - " + dr["kpi_max_weight"].ToString() + ")" };
                        TextBox txtbox = new TextBox { CssClass = "txtinput", Width = new Unit(30), ID = "txt" + dept + "_" + dr["kpi"].ToString() };
                        txtbox.ID = "txt" + dept + "_" + dr["kpi"].ToString();
                        
                        RangeValidator rv = new RangeValidator();
                        rv.ID = "rv" + dept + "_" + dr["kpi"].ToString();
                        rv.ControlToValidate = txtbox.ID;
                        rv.Type = ValidationDataType.Double;
                        rv.MinimumValue = dr["kpi_min_weight"].ToString();
                        rv.MaximumValue = dr["kpi_max_weight"].ToString();
                        rv.SetFocusOnError = true;                        
                        rv.Display = ValidatorDisplay.Dynamic;                        
                        rv.CssClass = "aboveBottom";
                        rv.ForeColor = System.Drawing.Color.Brown;
                        rv.Font.Size = new FontUnit(9);
                        rv.ErrorMessage = "valid_range_["+dr["kpi"].ToString()+"]:-(" + dr["kpi_min_weight"].ToString() + "-" + dr["kpi_max_weight"].ToString()+")";                        
                        rv.ToolTip = "Must be between " + dr["kpi_min_weight"].ToString() + " & " + dr["kpi_max_weight"].ToString();
                        
                        RequiredFieldValidator rfv = new RequiredFieldValidator();
                        rfv.ID = "rfv" + dept + "_" + dr["kpi"].ToString();
                        rfv.ControlToValidate = txtbox.ID;
                        rfv.ErrorMessage = dr["kpi"].ToString();
                        rfv.CssClass = "aboveBottom";
                        rfv.ForeColor = System.Drawing.Color.Brown;
                        rfv.Font.Size = new FontUnit(9);                        
                        rfv.BackColor = System.Drawing.Color.Transparent;
                        rfv.Display = ValidatorDisplay.None;

                        pnl.Controls.Add(lbl);
                        pnl.Controls.Add(new LiteralControl("   "));
                        pnl.Controls.Add(txtbox);
                        pnl.Controls.Add(lblBlank);
                        pnl.Controls.Add(new LiteralControl("   <br/><br/>"));
                        pnl.Controls.Add(rv);                        
                        rfvpnl.Controls.Add(rfv);
                    }
                }
                catch (Exception ex) { throw new ArgumentException("Error: "+ex.Message); }
                
            }

        }

Can you post your code, adding the validators and attaching them to the button or textbox?

can you please expose some sample on that what do you mean exactly as I've already tried with Grouping them.

bhagirathimfs 25-Jun-12 9:15am

<asp:TextBox ID="txtDate" Height="15px" ValidationGroup="test" runat="server" MaxLength="3" Width="40" AutoPostBack="true"
CausesValidation="true">
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ValidationGroup="test" runat="server" ErrorMessage="*"
ControlToValidate="txtDate" Display="Dynamic">
<asp:RegularExpressionValidator ID="revDate" ValidationGroup="test" runat="server" ControlToValidate="txtDate"
Display="Dynamic" ValidationExpression="^\d+$" ErrorMessage="Enter a Valid Number.">
<Asp:Button Id="btnSubmit" runat="server" ValidationGroup="test" Text="Submit">

I want to say this

Sunny_Kumar_ 26-Jun-12 0:19am

doesn't work.

bhagirathimfs 26-Jun-12 1:32am

Have you set the ValidationGroup Property of button .
Means:<Asp:Button Id="btnSubmit" runat="server" ValidationGroup="test" Text="Submit">

The ValidationGroup name should be same for all cases.
Like here test.

Solution 2

You need to have some button which triggers postback event and also you need to embed all these in validation groups.

kishhr, Validators always get fired on a postback that I do know. The problem is they're not getting fired after doing a postback but after that.
