Solution 3

Code for blank field validations:

C#

<asp:textbox id="TextBox1" value="" xmlns:asp="#unknown"></asp:textbox>
<asp:requiredfieldvalidator id="RequiredFieldValidator3" runat="server" errormessage="" forecolor="red" controltovalidate="TextBox1" validationgroup="A" initialvalue="" xmlns:asp="#unknown">*</asp:requiredfieldvalidator>

<asp:textbox id="TextBox2" textmode="Password" value="" xmlns:asp="#unknown"></asp:textbox>
<asp:requiredfieldvalidator id="RequiredFieldValidator4" runat="server" errormessage="" forecolor="red" controltovalidate="TextBox2" validationgroup="A" initialvalue="" xmlns:asp="#unknown">*</asp:requiredfieldvalidator>

<asp:button id="btn_submit" runat="server" text="Submit" onclick="btn_submit_Click" onclientclick="return confirm('Are you sure you want to enter details?');" validationgroup="A" xmlns:asp="#unknown" />

Code for entering details:

C#

protected void btn_submit_Click(object sender, EventArgs e)
{
//You code here
Response.Write("<script type='text/javascript'>");
Response.Write("alert('Your details has been submitted successfully.');");
Response.Write("</script>");
}

Solution 4

Hi,

you can add "Required field Validator " to your text boxes..

set controltovalidate property to textboxid
and error msg you can set as per your requirement.

for eg.

<asp:TextBox runat="server" id="txtName" />
    <asp:RequiredFieldValidator runat="server" id="reqName" controltovalidate="txtName" errormessage="Please enter your name!" />

and about your second question..
see the bolow link...

//asp validation to check for empty fields.

XML

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="rfvTextBox1" runat="Server" ValidationGroup="Submit"
            ControlToValidate="TextBox1" ErrorMessage="Cannt be empty"></asp:RequiredFieldValidator>
            <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="rfvTextBox2" runat="Server" ValidationGroup="Submit"
            ControlToValidate="TextBox2" ErrorMessage="Cannt be empty"></asp:RequiredFieldValidator>
            <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="rfvTextBox3" runat="Server" ValidationGroup="Submit"
            ControlToValidate="TextBox3" ErrorMessage="Cannt be empty"></asp:RequiredFieldValidator>
            <asp:Button ID="btnSubmit" runat="server" Text="Submit" ValidationGroup="Submit" Onclick="btnSubmit_Click" OnClientClick="return fnConfirm();" />

//Java script function
function fnConfirm()
{

C#

var result=confirm('Are you sure you want to Submit this data ?');
 if (result==true) 
        {                  
           return true;
        }
        else
        {
            return false;
        }
}

Note : If user click on ok system will allow to go for server side click event otherwise no.

//Confirmation message after saving successfully
if (result is true)
{
ScriptManager.RegisterClientScriptBlock(Me.Page,Me.GetType(),"Saved","alert('Records have been saved succesfully')",True);
return;
}
else
{

C#

ScriptManager.RegisterClientScriptBlock(Me.Page,Me.GetType(),"Saved","alert('Failed to save try again')",True);
return;

}

            var txt2 = document.getElementById('TextBox2');
            var txt3 = document.getElementById('TextBox3');
            
            if(txt1.value == '' || txt2.value == '' || txt3.value == '')
            {
                alert('please enter value');
                return false;
            }
            else
            {
