Introduction:
Here I will explain how to find or access controls in gridview footer template in asp.net using c#, vb.net with example or find controls in asp.net gridview footer row in c#, vb.net with example or get footer row textbox control values in gridview using asp.net in c#, vb.net with example.
Description:
In previous articles I explained crud operations (insert, update, delete) in gridview in asp.net, gridview examples in asp.net, display images from database using handler in asp.net, Bind Dropdownlist selected value in asp.net gridview, gridview rowdatabound event example in asp.net, Delete multiple rows in gridview using checkbox in asp.net and many articles relating to gridview, asp.net, c#,vb.net and jQuery. Now I will explain how to find or access controls in gridview footer template or row in asp.net using c#, vb.net with example.
In previous articles I explained crud operations (insert, update, delete) in gridview in asp.net, gridview examples in asp.net, display images from database using handler in asp.net, Bind Dropdownlist selected value in asp.net gridview, gridview rowdatabound event example in asp.net, Delete multiple rows in gridview using checkbox in asp.net and many articles relating to gridview, asp.net, c#,vb.net and jQuery. Now I will explain how to find or access controls in gridview footer template or row in asp.net using c#, vb.net with example.
To
access controls in gridview footer template or
row in asp.net we need to write
code like as shown below
TextBox txtname =
(TextBox)gvDetails.FooterRow.FindControl("txtpname");
TextBox txtprice =
(TextBox)gvDetails.FooterRow.FindControl("txtprice");
|
Column Name
|
Data Type
|
Allow Nulls
|
productid
|
Int(IDENTITY=TRUE)
|
Yes
|
productname
|
varchar(50)
|
Yes
|
price
|
varchar(50)
|
Yes
|
Now
create one new stored procedure “Crudoperations” in your sql
server database to perform insert, select, update and delete operations with
single procedure for that follow below script
CREATE PROCEDURE
CrudOperations
@productid int
= 0,
@productname varchar(50)=null,
@price int=0,
@status varchar(50)
AS
BEGIN
SET NOCOUNT ON;
--- Insert New Records
IF @status='INSERT'
BEGIN
INSERT INTO
productinfo1(productname,price) VALUES(@productname,@price)
END
--- Select Records in Table
IF @status='SELECT'
BEGIN
SELECT productid,productname,price FROM
productinfo1
END
--- Update Records in Table
IF @status='UPDATE'
BEGIN
UPDATE productinfo1 SET
productname=@productname,price=@price WHERE productid=@productid
END
--- Delete Records from
Table
IF @status='DELETE'
BEGIN
DELETE FROM
productinfo1 where productid=@productid
END
SET NOCOUNT OFF
END
|
In
case if you have any doubts to create procedure check below article
Once
we finish stored procedure creation in database now open your aspx page and
write the code like as shown below
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"
runat="server">

</head>

</form>
</body>
</html>

After completion of aspx page add following namespaces in
codebehind
C#
Code
using System;
using
System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using System.Drawing;
|
After completion of adding namespaces you need to write the
code like as shown below
protected void Page_Load(object
sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridview();
}
}
protected void BindGridview()

cmd.CommandType= CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@status","SELECT");
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Close();
if (ds.Tables[0].Rows.Count > 0)
{
gvDetails.DataSource = ds;
gvDetails.DataBind();
}
else {
ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
gvDetails.DataSource = ds;
gvDetails.DataBind();
int columncount =
gvDetails.Rows[0].Cells.Count;
gvDetails.Rows[0].Cells.Clear();
gvDetails.Rows[0].Cells.Add(new TableCell());
gvDetails.Rows[0].Cells[0].ColumnSpan = columncount;
gvDetails.Rows[0].Cells[0].Text = "No
Records Found";
}
}
}
protected void gvDetails_RowCommand(object
sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("AddNew"))
{
TextBox txtname =
(TextBox)gvDetails.FooterRow.FindControl("txtpname");
TextBox txtprice =
(TextBox)gvDetails.FooterRow.FindControl("txtprice");
crudoperations("INSERT",
txtname.Text, txtprice.Text, 0);
}
}

sender, GridViewEditEventArgs e)
{
gvDetails.EditIndex = e.NewEditIndex;
BindGridview();
}
protected void gvDetails_RowCancelingEdit(object sender, GridViewCancelEditEventArgs
e)
{
gvDetails.EditIndex = -1;
BindGridview();
}
protected void gvDetails_PageIndexChanging(object sender, GridViewPageEventArgs
e)
{
gvDetails.PageIndex = e.NewPageIndex;
BindGridview();
}
protected void gvDetails_RowUpdating(object
sender, GridViewUpdateEventArgs e)
{
int productid = Convert.ToInt32(gvDetails.DataKeys[e.RowIndex].Values["productid"].ToString());
TextBox txtname =
(TextBox)gvDetails.Rows[e.RowIndex].FindControl("txtProductname");

}

{

string productname =
gvDetails.DataKeys[e.RowIndex].Values["productname"].ToString();
crudoperations("DELETE",productname,"",productid);
}
protected void crudoperations(string
status, string productname, string price, int
productid)
{
using (SqlConnection con = new
SqlConnection("Data
Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB"))
{
con.Open();
SqlCommand cmd = new SqlCommand("crudoperations", con);
cmd.CommandType= CommandType.StoredProcedure;
if(status=="INSERT")
{
cmd.Parameters.AddWithValue("@status",status);
cmd.Parameters.AddWithValue("@productname",productname);
cmd.Parameters.AddWithValue("@price",price);
}
else if(status=="UPDATE")
{

cmd.ExecuteNonQuery();
lblresult.ForeColor = Color.Green;
lblresult.Text = productname+"
