First of all, just take a gridview on your design page and fill data as below ::
protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        { 
          BindGrid();
        }
    }

    protected void BindGrid()
    {
        gvDetails.DataSource = this.getData();
        gvDetails.DataBind();
    }

    private DataTable getData()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("UserId", typeof(Int32));
        dt.Columns.Add("Name", typeof(string));
        dt.Columns.Add("Designation", typeof(string));
        dt.Columns.Add("Department", typeof(string));

        DataRow dr = dt.NewRow();

Code for showing Attractive Validation hints and Alert Message using JavaScript

Image
In this blog i am going to show how to alert users with message in a very attractive way while entering values in textbox areas (i.e. Validation Hint) and how to get values from HTML controls and show those values in alert message through JavaScript.
      Validation Hints is a simple script that aides in form validation. It makes sure that password and username fields are the specified length, and can even validate against regular expressions. Small and handy.
First of add all the functions and the CSS code given below inside the <head> tag ::

  <style type="text/css"> form { width:500px; border:1px solid #ccc; } fieldset { border:0; padding:10px; margin:10px; position:relative; } label { display:block; font:normal 12px/17px verdana; } input {width:160px;}

How to access different controls within the GridView control in Asp.Net(C#)

In this blog i am going to show you how to find different controls within the GridView control e.g. TextBox control, Button control, ListBox control, DropDown, etc.

On the Button click event, I will print the values that are either entered (TextBox) or selected (DropDownList and ListBox). Let's see how this can be done ::

protected void Button1_Click(object sender, EventArgs e)
{
    // Iterates through the rows of the GridView control
    foreach (GridViewRow row in GridView1.Rows)
    {
        // Selects the text from the TextBox
        // which is inside the GridView control
        string textBoxText = ((TextBox)row.FindControl("TextBox1")).Text;
        Response.Write(textBoxText);

        // Selects the text from the DropDownList
        // which is inside the GridView control
        string dropDownListText = ((DropDownList)row.FindControl("DropDownList1")).SelectedItem.Value;
        Response.Write(dropDownListText);

        // Selects items from the…

How to show empty gridview when no data is available to display in Asp.Net- C#

Image
In this blog i am going to describe how we could add a custom message in GridView in Asp.Net(c#) in case data is not available in database/ datatable, etc. through code window (Although GridView provides direct property for this when data not available and users could use that property easily but in many case programmer wants to add message through code)



First of all in the design page(.aspx) place a GridView control as:

<div>
        <asp:GridView ID="TestGrid" runat="server">
        </asp:GridView>
</div>

 I used a very simple gridview without any styl& design, just to show message when data not available through code window.


Now, in the code behind file(.aspx.cs) write the code as ::

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            FillTestGrid();
        }
    }
    protected void FillTestGrid()
    {
        DataTable dt = new DataTable();

        dt.Columns.Add("UserId&q…
