I have taken two select commands in my grid view, one is accept and other is reject. So, I need to display message on different page not the same page. As the user clicks on accept it should display message as accepted and on reject it should display reject. But i am not getting away how to do it as I have not taken template in grid view. So I humbly request for help in it.
Since your question is only about "send a message on a different page using select command" One way to achieve this is using session variables within C# .NET application.
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
String strStatus = "Accepted";
Session["key1"] = strStatus;
string BrowserSettings = "status=no,toolbar=no,menubar=no,location=no,resizable=no," +
"titlebar=no, addressbar=no, width=600 ,height=750";
string URL = "StatusWebForm.aspx";
string scriptText = "window.open('" + URL + "','_blank','" + BrowserSettings + "');";
ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "ClientScript1", scriptText, true);
}
This ScriptManager concept was answered by Mahantesh, so I want to give him credit for that.
On second WebForm (.aspx.cs) page where you want to display the message, add a Label and Page_Load event.
public partial class StatusWebForm : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
String strStatus = (String)Session["key1"];
lblStatus.Text = strStatus;
}
}
i am developing webform with gridview. I have a problem, the value of checkbox doesn't save in the table. I've tried everything nothing is working. After i press a button, value doesn't store.
And as you can see in my code, i don't use id for unidentified of each particular row, instead id i use foreach
protected void Button_Submit_Onclick(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView2.Rows)
{
con.ConnectionString = ConfigurationManager.ConnectionStrings["TestDeductionsConnectionString2"].ToString();
bool private1 = (row.FindControl("CheckBox1") as CheckBox).Checked;
SqlCommand cmd = new SqlCommand("insert into DetailCosts(private) values(#private1)", con);
if (private1 == true)
{
cmd.Parameters.Add(new SqlParameter("#private1", SqlDbType.Bit));
cmd.Parameters["#private1"].Value = 1;
//cmd.Parameters.Add("#private1", SqlDbType.Bit).Value = 1;
}
else
{
cmd.Parameters.Add(new SqlParameter("#private1", SqlDbType.Bit));
cmd.Parameters["#private1"].Value = 0;
//cmd.Parameters.Add("#private1", SqlDbType.Bit).Value = 0;
}
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}}
and there is a code with my Gridview:

At the back end code, i tried to retrieve the first column and specific rows but it throw me empty. the code below is how i retrieve.
int index = Convert.ToInt32(e.RowIndex);
string sapNo1 = GridView1.Rows[index].Cells[0].Text;
string partNo = GridView1.Rows[index].Cells[1].Text;
string partDesc = GridView1.Rows[index].Cells[3].Text;
I try to show all the value for sapNo1, it throw me blank but for partNo it will show the data in the gridview.
anyone has any idea about this?
I am really appreciate your help and comment!
As your first column is a linkbutton so retrieve that as it is then find the value.
string sapNo1 = GridView1.Rows[index].Cells[0].Text; // wrong code to retrieve data from linkbutton in a gridview
Modify this as :
LinkButton linkbtn =(LinkButton)GridView1.Rows[index].FindControl("LinkButton1");
string sapNo1 = linkbtn.Text;
or
string sapNo1 =(GridView1.Rows[index].FindControl("LinkButton1") as LinkButton).Text;
You can't get the controls properties present inside TemplateField like that, you need to find the control like this:-
LinkButton LinkButton1 = (LinkButton)GridView1.Rows[index].Cells[0]
.FindControl("LinkButton1");
After this you can simply fetch the properties of this control:-
string sapNo1 = LinkButton1.Text;
you can get the link button description by the below code
protected void Link_Button_Command(object sender, CommandEventArgs e)
{
try
{
LinkButton button = (LinkButton)sender;
string name = button.ToString();
}
catch (Exception ex)
{
lbl_message.Text = ex.Message;
}
}
I want to display the "NDA ID" in a label When the user click on the select link in the grid view. But it gives the error as "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index".

Code behind
protected void grdNDA_SelectedIndexChanged(object sender, EventArgs e)
{

}
You should change this line
lblValues.Text = "<b>ID:</b> " + grdNDA.SelectedRow.Cells[1].Text;
It worked using this
protected void form1_Load(object sender, EventArgs e)
{
System.Data.DataTable dt = new System.Data.DataTable();
System.Data.DataRow dr;
dt.Columns.Add("NDAid");
dt.Columns.Add("ComName");
dt.Columns.Add("Country");
dt.Columns.Add("Date");
for (int i = 1; i <= 5; i++)
{
dr = dt.NewRow();
dr[0] = i;
dr[1] = "Company " + i;
dr[2] = "Country " + i;
dr[3] = DateTime.Now;
dt.Rows.Add(dr);
}
grdNDA.DataSource = dt;
grdNDA.DataBind();
}
protected void grdNDA_SelectedIndexChanged(object sender, EventArgs e)
{
lblValues.Text = "<b>ID:</b> " + grdNDA.SelectedRow.Cells[1].Text;
