Get Validate Textbox Controls Inside Gridview using JavaScript in Asp.net

Dec 29, 2014
Introduction

Here I will explain how to get or validate textbox controls inside of
asp.net gridview using JavaScript or validate asp.net gridview footer controls (textbox, dropdownlist, checkbox, radio button etc..) values in JavaScript.


To get or validate textbox controls inside of asp.net gridview using JavaScript we need to write the code like as shown below

Syntax to Get or Validate Gridview Controls in JavaScript


<script type="text/javascript">
function GetGridFooterRowvalues() {
var fuid = document.getElementById('<%=((TextBox)gvUserInfo.FooterRow.FindControl("txtUserId")).ClientID %>');
if (fuid.value!= '') {
alert('UserId:' + fuid.value)
}
else{
alert'Please enter userid')
}
}
</script>
If you want see it in complete example open your aspx page and write the following code


<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>get or validate textbox controls inside gridview using javascript</title>
<script type="text/javascript">
function GetGridFooterRowvalues()
{
var fuid = document.getElementById('<%=(gvUserInfo.FooterRow.FindControl("txtUserId")).ClientID %>');
var funame = document.getElementById('<%=(gvUserInfo.FooterRow.FindControl("txtUserName")).ClientID %>');
var fueducation = document.getElementById('<%=(gvUserInfo.FooterRow.FindControl("txtEducation")).ClientID %>');
if (fuid.value != '' && funame.value != '' && fueducation.value != '') {
alert('UserId:' + fuid.value + ';UserName:' + funame.value + ';Education:' + fueducation.value)
}
else{
alert("Please enter all the values")
}
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="gvUserInfo" runat="server" AutoGenerateColumns="false" ShowFooter="true">
<HeaderStyle BackColor="#df5015" Font-Bold="true" ForeColor="White" />
<Columns>
<asp:TemplateField HeaderText="UserId">
<ItemTemplate>
<asp:Label id="lblUserid" runat="server"  Text='<%# Eval("UserId") %>' />
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtUserId" runat="server" />
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="UserName">
<ItemTemplate>
<asp:Label id="lblUsername" runat="server" Text='<%# Eval("UserName") %>'/>
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtUserName" runat="server" />
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Education">
<ItemTemplate>
<asp:Label id="lblEducation" runat="server" Text='<%# Eval("Education") %>'/>
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtEducation" runat="server" />
</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Button ID="btnGet" Text="Get Footer Values" runat="server" OnClientClick="GetGridFooterRowvalues()" />
</div>
</form>
</body>
</html>
After that write the following code in code behind

C# Code


using System;
using System.Data;

public partial class Default3 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("UserId", typeof(Int32));
            dt.Columns.Add("UserName", typeof(string));
            dt.Columns.Add("Education", typeof(string));
            dt.Rows.Add(1, "Suresh Dasari", "B.Tech");
            dt.Rows.Add(2, "Rohini Dasari", "Msc");
            dt.Rows.Add(3, "Madhav Sai", "MS");
            dt.Rows.Add(4, "Praveen", "B.Tech");
            dt.Rows.Add(6, "Sateesh", "MD");
            dt.Rows.Add(7, "Mahesh Dasari", "B.Tech");
            dt.Rows.Add(8, "Mahendra", "CA");
            gvUserInfo.DataSource = dt;
            gvUserInfo.DataBind();
        }
    }
}
VB.NET Code


Imports System.Data
Partial Class _Default
    Inherits System.Web.UI.Page
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
        If Not IsPostBack Then
            Dim dt As New DataTable()
            dt.Columns.Add("UserId", GetType(Int32))
            dt.Columns.Add("UserName", GetType(String))
            dt.Columns.Add("Education", GetType(String))
            dt.Rows.Add(1, "Suresh Dasari", "B.Tech")
            dt.Rows.Add(2, "Rohini Dasari", "Msc")
            dt.Rows.Add(3, "Madhav Sai", "MS")
            dt.Rows.Add(4, "Praveen", "B.Tech")
            dt.Rows.Add(6, "Sateesh", "MD")
            dt.Rows.Add(7, "Mahesh Dasari", "B.Tech")
            dt.Rows.Add(8, "Mahendra", "CA")
            gvUserInfo.DataSource = dt
            gvUserInfo.DataBind()
        End If
    End Sub
End Class
