Question

When I was changing page number, I was getting error

"The GridView 'GridView1' fired event PageIndexChanging which wasn't handled."

But afterwards, I searched and try to put this code in PageIndexChanging even, still it isn’t working :

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.SelectedIndex = e.NewPageIndex;
    GridView1.DataSource = SqlDataSource1;
    GridView1.DataBind();
}

Originally, when user prompts to page, I am showing all data on gridview, then user can search data, and upon clicking Search button, below code is executing :

 protected void Button1_Click(object sender, EventArgs e)
{
    DateTime dt1 = DateTime.Now, dt2 = DateTime.Now;
    Connection.getCon();
    try
    {
         dt1 = Convert.ToDateTime(TextBox3.Text);
         dt2 = Convert.ToDateTime(TextBox4.Text).AddDays(1);
        lblError.Visible = false;
    }
    catch (Exception exc) {
        lblError.Visible = true;
    }


    string cmd = "select * from tblLogs where (users like '%"+TextBox1.Text.Trim()+"%') and (request like '%"+TextBox2.Text.Trim()+"%') and (requesttime>='"+dt1+"') and (requesttime<'"+dt2+"') ";
    SqlDataSource1.SelectCommand = cmd;
    DataView dv= (DataView) SqlDataSource1.Select(DataSourceSelectArguments.Empty);
    GridView1.DataSourceID = null;
    GridView1.DataSource= dv;
    GridView1.DataBind();
    //GridView1.AllowPaging = false;

}

Now, I am not getting any error, but still page is not changing and staying on 1.

Thanks.

You are using the wrong property in your PageIndexChanging event, it should be PageIndex instead of SelectedIndex:

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataSource = SqlDataSource1;
    GridView1.DataBind();
}
