there are a few mistakes in your code, i recommend you to read about CRUD Operations using ADO.Net and C# in ASP.Net, how to use SqlConnection and SqlCommand types. When you work with asp.net web forms you can use SqlDataSource control to provide data for your controls.

CheckBox is not working when I am pressing the button

I am working with Asp.Net C# and want to take the id of the row with a checkbox from the GridView.
With the code above if is checked the only think i am getting with debug is:
chk: {Text = "" Checked = false}
What i am doing wrong and how i can fix this?

This is caused by the fact that you always bind your GridView1 with data,
even on post-back. This is causing that all check box-es remain unchecked.
Remove grid loading if you are in post-back, and it should work fine.
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
string query = "SELECT * FROM routedoc WHERE Recipient=#user ";
string user = Session["user"].ToString();
MySqlConnection con = new MySqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["imagingConnectionString"].ConnectionString);
MySqlCommand cmd = new MySqlCommand(query, con);
cmd.Parameters.AddWithValue("#user", user);
con.Open();
DataTable dataTable = new DataTable();
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
da.Fill(dataTable);
GridView1.DataSource = dataTable;
GridView1.DataBind();
BindDropDown();
}
}
If you, however, need to load grid even in post-back, I will tell you a fix for that.

Whenever you bind a data to a data control in Page_Load event, please consider using Page.IsPostBack
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
// bind data
}
}
This is because, when you click a button, your page will be still refreshed, which means you will bind the same data to gridview again, resulting in unchecked checkboxes. You can check whether the page is loaded by a button click (Page.IsPostBack) or the page is loaded the first time (!Page.IsPostBack), and do your data binding accordingly.
Hope this makes sense!

asp.net gridview Sorting by date

I am sorting my date with my sql query and I get a proper result.
But as I apply
gridview.UseAccessibleHeader = true;
gridview.HeaderRow.TableSection = TableRowSection.TableHeader;
to my gridview. The sorted data gets unsorted.

this.gridviewname.MasterTemplate.EnableSorting = true;
this.RadGridView1.MasterTemplate.EnableSorting = True
SortDescriptor descriptor = new SortDescriptor();
descriptor.PropertyName = "Yourcolumnname";
descriptor.Direction = ListSortDirection.Ascending;
this.gridviewname.MasterTemplate.SortDescriptors.Add(descriptor);
descriptorcolumnname As New SortDescriptor()
descriptorShipName.PropertyName = "columnname"
descriptorShipName.Direction = ListSortDirection.Ascending
try this

Try this code which is working fine for me.

Gridview Paging ASP.NET with Pager Panel outside Gridview

This is my first time for using ASP.NET to develop website.
I want to show my data from database in a GridView with Paging function and I can implement it by using OnPageIndexChanging="GridView1_PageIndexChanging" but I want to use my own pager so the question is
"How can I link my pager (the right bottom in the pic) to the gridview instead the pager which generated by the ASP.NET"
Pics:
This is my code in aspx
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" CssClass="table table-bordered table-condensed table-striped table-primary table-vertical-center"
PageSize="3" AllowPaging="True"
OnPageIndexChanging="GridView1_PageIndexChanging">
<Columns>
<asp:BoundField DataField="UNIT_ID" HeaderText="รหัส" SortExpression="unitid">
<HeaderStyle CssClass="center" />
<ItemStyle Width="10%" CssClass="center" />
</asp:BoundField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
Code in cs
public partial class _Default : Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
bindGridView();
}
protected void bindGridView() {
string sqltxt = "select * from drug_units"; //where UNIT_ID =:unitid";
CommandData comm = new CommandData();
comm.SetCommandText(sqltxt);
//comm.AddInputParameter("unitid", "5");
List<DrugsUnit> dy = new List<DrugsUnit>();
comm.ExecuteNonQuery();
dy = comm.ExecuteToList<DrugsUnit>();
GridView1.DataSource = dy;
/*BoundField boundField = new BoundField();
boundField.DataField = "UNIT_ID";
boundField.HeaderText = "ID";
boundField.SortExpression = "ID";
boundField.HeaderStyle.CssClass = "center";
boundField.ItemStyle.CssClass = "center";
GridView1.Columns.Add(boundField);*/
GridView1.DataBind();
GridView1.HeaderRow.TableSection = TableRowSection.TableHeader;
}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
bindGridView();
}
}

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Pager)
{
upGridPager.Update();
e.Row.SetRenderMethodDelegate(new RenderMethod((w, r) =>
{
e.Row.SetRenderMethodDelegate(null);
using (var ms = new StringWriter())
using (var writer = new HtmlTextWriter(ms))
{
e.Row.RenderControl(writer);
GridPager.InnerHtml = "<table>" + ms.ToString() + "</table>";
}
}));
}
The aspx could look like this (outside of your grid)
<asp:UpdatePanel ID="upGridPager" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div runat="server" id="GridPager" />
</ContentTemplate>
</asp:UpdatePanel>

set values to TextBox in Item template of gridview

I'm working with Outward Challan Detail, in which I need to show the results on a form by a gridview.

How could I assign values in the textbox inside my templates fields that are in my gridview by using dataReader or DataSet?

}
}

You should directly bind the DataTable Column to TextBox inside the TemplateField like...
<asp:TextBox ID="txtDispatchQuantity" runat="server" Text='<%# Eval("ColumnNameInDataSetTable") %>' />
This directly binds the values to TextBoxes. You can do this for all other TextBoxes.

TextBox txtDispatchQuantity = (TextBox)e.Row.FindControl("txtDispatchQuantity");
var dataRow = (DataRowView)e.Row.DataItem;
var Dispatch_Qty = "Dispatch_Qty";
var check = dataRow.Row.Table.Columns.Cast<DataColumn>().Any(x => x.ColumnName.Equals(Dispatch_Qty, StringComparison.InvariantCultureIgnoreCase));
if (check)
{
// Property available
txtDispatchQuantity.Text =ds1.Tables[0].Rows[0][7].ToString();
}

protected void gvOutDCItemDetails_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//if ((e.Row.RowState & DataControlRowState.Edit) > 0)
//{
DropDownList ddList = (DropDownList)e.Row.FindControl("ddrProcess");
//bind dropdownlist
SqlCommand cmd = new SqlCommand("sp_getProcess", con1);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
DataTable dt = ds.Tables[0];
//DataTable dt = con1.GetData("Select category_name from category");
ddList.DataSource = dt;
ddList.DataTextField = "PName";
ddList.DataValueField = "Process_Id";
ddList.DataBind();
ddList.Items.Insert(0,new ListItem("--SELECT--","0"));
TextBox txtDispatchQuantity = (TextBox)e.Row.FindControl("txtDispatchQuantity");
var dataRow = (DataRowView)e.Row.DataItem;
var Dispatch_Qty = "Dispatch_Qty";
var check = dataRow.Row.Table.Columns.Cast<DataColumn>().Any(x => x.ColumnName.Equals(Dispatch_Qty, StringComparison.InvariantCultureIgnoreCase));
if (check)
{
// Property available
txtDispatchQuantity.Text =ds1.Tables[0].Rows[0][7].ToString();
}
}
if (e.Row.RowType == DataControlRowType.Footer)
{
// Label lblTotalPrice = (Label)e.Row.FindControl("Total_Amount");
//lblTotalPrice.Text = total.ToString();
// txttotalAmount.Text = Total.ToString();
}
}

A short way with Simple and Inner Select, For use in ASPX code with no Code Behind:
....
<ItemTemplate>
<tr>
<td>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("COrder") %>' />
</td>
<td>
<asp:Label ID="TitleLabel" runat="server" Text='<%# Eval("CText") %>' />
</td>
<td>
Delete
</td>
</tr>
</ItemTemplate>
....
