When I click on add button, footer item data will insert into my database but is insert twice. It is in debug mode and jumping around everywhere.
it show "The process or thread has changed since last step."


You are sending the insert command again by calling gvEmpList.DataSource = GetData(cmd); inside btnAdd_Click. Please check it. The cmd object inside btnAdd_Click is an insert command.


Remove following code from btnAdd_Click
gvEmpList.DataSource = GetData(cmd);
gvEmpList.DataBind();
And call following method
BindData();

GridView gvItems = (GridView)e.Row.FindControl("gvItems");
// new code to send reference to gvItems_RowDataBound
gvItems.RowDataBound += new GridViewRowEventHandler(gvItems_RowDataBound);
int id = Convert.ToInt32(purchaseRequisitionID);
using (SqlConnection conn = new SqlConnection(constr))

if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList ddlMeasure = e.Row.FindControl("ddlMeasure") as DropDownList;
if(ddlMeasure == null)
{
}
}
}
But I cannot see the drop down list as it returns a null value (as I know it is not a DataRow) but how can I see the footer row and the elements in footer row so that I can add another Item to the order/populate DropDownList etc.
Have been trying to sort this for some time and cannot find a working solution so any pointer(s) will be very much appreciated.

You need to use DataControlRowType.Footer.
protected void gvItems_RowDataBound(object sender, GridViewRowEventArgs e)
{
//check if the row is a footer row
if (e.Row.RowType == DataControlRowType.Footer)
{
DropDownList ddlMeasure = e.Row.FindControl("ddlMeasure") as DropDownList;
if (ddlMeasure != null)
{
ddlMeasure.Items.Insert(0, new ListItem("DLL Found!", "-1"));
}
}
}

Add info using textbox into gridview after retrieving data from database C#

I'm retrieving data from database into the grid for 5 column, there is another 3 columns beside that which I want to fill in using textbox input (using different button).
How to fetch the input from the textbox into the grid after I retrieve the data from database?
Here is the front looks like:
Here is the coding:
<form id="form1" runat="server">
<div>
<asp:Label ID="Label1" runat="server" Text="BNE No: "></asp:Label>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Search From Database" />
<br />
<asp:Label ID="Label3" runat="server" Text="Label"></asp:Label>
<br />

</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ECN No">
<ItemTemplate>
<asp:Label ID="Label5" runat="server" Text='<%#Bind("KVNo") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Rec Date">
<ItemTemplate>
<asp:Label ID="Label6" runat="server" Text='<%#Bind("ReceivedDate") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Issued Date">
<ItemTemplate>
<asp:Label ID="Label7" runat="server" Text='<%#Bind("IssuedDate") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Status">
<ItemTemplate>
<asp:Label ID="Label8" runat="server" Text='<%#Bind("Status") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Location">

<asp:TemplateField HeaderText="Date">
<ItemTemplate>
<asp:Label ID="Label11" runat="server" Text=''></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
</form>
Here is the behind code where I use to retrieve the data by using button 1
protected void Button1_Click(object sender, EventArgs e)//this Button use To call multiple data from database named tblBNE into GridView
{
count = 0;
con.Open();
OleDbCommand cmd = con.CreateCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT [BNENo],[KVNo],[ReceivedDate],[IssuedDate],[Status] FROM [tblBNE] where BNENo='" + TextBox1.Text + "' or BNENo='" + TextBox2.Text + "' ";
cmd.ExecuteNonQuery();
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
da.Fill(dt);
count = Convert.ToInt32(dt.Rows.Count.ToString());
GridView1.DataSource = dt;
GridView1.DataBind();
con.Close();
if (count == 0)
{
Label3.Text = "record not found";
}
}
So, I want to use button 3 = insert to grid to fill into label9 to 11 using textbox3 to 5. How can I do that?
Thank you in advance :)

How to hide duplicate data from Gridview?

how am i be able to hide those duplicate columns using gridview command?
im using
nested gridview and left Outer Join on sqlcommand i joined two database.. so yeah this is my next problem
this is my code
protected void NewConnection()
{
SqlCommand cmd = new SqlCommand("SELECT a.*,b.ID,b.Firstname,b.Middlename,b.Lastname,b.Friendswith,b.Amount from [User_TBL_DB] a LEFT OUTER JOIN [Friends_TBL_DB] b ON a.ID=b.Friendswith", conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
conn.Close();
GridView1.DataSource = ds;
GridView1.DataBind();
GroupGridView(GridView1.Rows, 0,0);
GridView1.Columns[3].Visible = false;
GridView1.Columns[4].Visible = false;
GridView1.Columns[7].Visible = false;
GridView1.Columns[8].Visible = false;
GridView1.Columns[9].Visible = false;
GridView1.Columns[10].Visible = false;
GridView1.Columns[11].Visible = false;
foreach (GridViewRow Separate in GridView1.Rows)
{
GridView gv2 = ((GridView)Separate.FindControl("GridView2"));
gv2.DataSource = ds;
gv2.DataBind();
string strfirstname = ((Label)Separate.FindControl("lblfirstname")).Text;
string strmiddlename=((Label)Separate.FindControl("lblmiddlename")).Text;
string strlastname = ((Label)Separate.FindControl("lbllastname")).Text;
string strage = ((Label)Separate.FindControl("lblage")).Text;
string strsex = ((Label)Separate.FindControl("lblsex")).Text;
string stramount = ((Label)Separate.FindControl("lblamount")).Text;
string strID1 = ((Label)Separate.FindControl("lblid")).Text;
foreach (GridViewRow grouplist in gv2.Rows)
{
string strID2 = ((Label)grouplist.FindControl("lblfriendswith2")).Text;
if (strID1 == strID2)
{
grouplist.Visible = true;
}

If you don't need the duplicate data Use distinct in query.
So your SqlCommand should look like,
SqlCommand cmd = new SqlCommand("SELECT DISTINCT a.*,b.ID,b.Firstname,b.Middlename,b.Lastname,b.Friendswith,b.Amount from [User_TBL_DB] a LEFT OUTER JOIN [Friends_TBL_DB] b ON a.ID=b.Friendswith", conn);

The problem is not your GridView control, the data binded to the GridView is the real issue, since the task of the GridView is just to show data. Performing a LEFT OUTER JOIN you're getting a lot of duplicates. Use the DISTINCT statement to remove duplicates:
SqlCommand cmd = new SqlCommand("SELECT DISTINCT a.*,b.ID,b.Firstname,b.Middlename,b.Lastname,b.Friendswith,b.Amount from [User_TBL_DB] a LEFT OUTER JOIN [Friends_TBL_DB] b ON a.ID=b.Friendswith", conn);

Gridview edit mode for more that one row

I have a Gridview that allows user to edit and delete the records. I am using .net 3.5 using C#.
When I have just one record my edit command is working fine but problem comes when there are more that 1 record in my gridview.
In this case while binding the controls it it is unable to find the controls the second time and thus throws the error.
Here is my code:
protected void gdScheduleNew_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (ViewState["Updating"].Equals(true))
{
TextBox txtactsta = (TextBox)e.Row.FindControl("txtactualstartDate");
TextBox txtactend = (TextBox)e.Row.FindControl("txtactualendDate");
LinkButton lnkUpdate = (LinkButton)e.Row.FindControl("lnkUpdate");
txtactsta.Attributes.Add("ReadOnly", "true");
txtactend.Attributes.Add("ReadOnly", "true");
}
}
}
markup code is:
<asp:GridView ID="gdScheduleNew" runat="server" Width="100%" SelectedIndex="0"

The error is on this line: txtactsta.Attributes.Add("ReadOnly", "true");:
object reference no set to an instance of object
How can I fix this?

Doesn't gdScheduleNew_RowDataBound get called for every row in your gridview? txtactualstartDate and txtactualendDate only exist on edit rows, they do not exist on non editing rows.
Try this:
if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowState == DataControlRowState.Edit)
