what i told is that first you create a datatable with all the columns which you require and then when you click add new button add a row to that datatable. And you can bind the datagrid with the datatable directly i.e dg.datasourse = datatable.

Fllowing is the code what I have used:
private void ibtnAdd_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
Classes.CChecklist cchecklist = new Classes.CChecklist();
dgChecklist.AutoGenerateColumns = true;
DataTable dt = new DataTable("CheckList");
int cnt;
if(lbISOClauseNo.Items.Count > 0 && lbISODesc.Items.Count > 0 && txtExpected.Text != "" && txtTimeAllocated.Text != "")
{
for(cnt = 0 ; cnt < lbISOClauseNo.Items.Count ; cnt++)
{
if(cnt == lbISOClauseNo.Items.Count -1)
{
htxtFISOClauseNo.Value += lbISOClauseNo.Items[cnt].Value;
htxtFISOClauseDesc.Value += lbISODesc.Items[cnt].Value;
}
else
{
htxtFISOClauseNo.Value += lbISOClauseNo.Items[cnt].Value + "," ;
htxtFISOClauseDesc.Value += lbISODesc.Items[cnt].Value + "," ;
}
}
htxtFExpected.Value = txtExpected.Text;
htxtFTimePlanned.Value = txtTimeAllocated.Text;
cnt = Int32.Parse(htxtFChecklistNo.Value);
cnt++;
htxtFChecklistNo.Value = cnt.ToString();
}
//Checklist No
DataColumn dc = new DataColumn();
dc = dt.Columns.Add("Checklist No",System.Type.GetType("System.Int32"));
dc.Caption = "checklist_no";
//ISO Clause No
dc = dt.Columns.Add("ISO Clause No",System.Type.GetType("System.String"));
dc.Caption = "checklist_isoclause";
//Activities
dc = dt.Columns.Add("Activities",System.Type.GetType("System.String"));
dc.Caption = "checklist_activities";
//Expected Evidence
dc = dt.Columns.Add("Expected",System.Type.GetType("System.String"));
dc.Caption = "checklist_expected";
//Time Planned
dc = dt.Columns.Add("Time Allocated",System.Type.GetType("System.String"));
dc.Caption = "checklist_timeplanned";
DataRow dr = dt.NewRow();
dr["Checklist No"] = htxtFChecklistNo.Value;
dr["ISO Clause No"] = htxtFISOClauseNo.Value;
dr["Activities"] = htxtFISOClauseDesc.Value;
dr["Expected"] = htxtFExpected.Value;
dr["Time Allocated"] = htxtFTimePlanned.Value;
dt.Rows.Add(dr);
//Bind Datatable with DataGrid
dgChecklist.DataSource = dt;
dgChecklist.DataBind();
//Clear all the textbox and listbox.
lbISOClauseNo.Items.Clear();
lbISODesc.Items.Clear();
txtExpected.Text = "";
txtTimeAllocated.Text = "";
htxtFExpected.Value = "";
htxtFISOClauseDesc.Value = "";
htxtFISOClauseNo.Value = "";
htxtFTimePlanned.Value = "";
}
Whenever I click on add button datatable gets created again and I lose my last record.So I am in problem.
Please tell me how do I handle this

what you do is when the add button is clicked then you check whether you are having the datatable in the viewstate. If yes then use that(datatable in viewstate) to add the new record and if the datatable is not present in the viewstate(it will happen when the add button is clicked for the first time) then create a new datatable and put it into the viewstate. Finally attach that datatable which is there in viewstate to the datagrid.

Hi,
But how do I check whether datatable is created or not???
Thanks and Regards.
|
|
|
|
|
you can check like this
if(ViewState["daa"]!=null)
{
//Datatable is available in viewstate.
}
else
{
//Not available.
}

Hi again,
Now can u please tell me how do I save that Datagrid into Database???
Thanks and regards,
Varsha
|
|
|
|

Hi,
You can send the records from front end as comma separated sting and then in your stored procedure you can separate it and store it into the database.

Hi,
Thanks for reply.Can't we directly fire a query in a loop where I pass the datatable to my Class file.I mean Y do we have to write a Stored Procedure.
Thanks and Regards
|
|
|
|
|
ya sure it can be done like that also. You can go through the records one by one(in a loop) and then execute a insert statement to insert the record in the database.
Best Regards,
Apurva Kaushal

Hi,
Will it manage the transaction,I mean it may happen that some records are inserted and other didnt.Can we pass datatable to Insert function which is in class file or can we define property for this?What is ur suggestion on this???
Whatever your suggestion please give me the syntax for the same.
Thanks and Regards.
|
|
|
|

Hi,
Probably we can maintain the transactiob in the data access layer also. But that i have never used. But for the second option(stored procedure) we can maintain it easily.
Best Regards,
Apurva Kaushal

|
|
|

Sorry to say I have not used any of the methods as I dont know much about Stored Procedure and the layer which u are saying that also I dont know.
Thanks and Regards.

I guess you create css classes for the hyperlink column, the sample can be found from here[^]:

I recently discovered so much can be done by using xml and xslt transformation. But i wanted which would be more efficient desiging pages using xml and xml transformation or using datagrid and other control while displaying data

Depends on your requirements.
If you want someone, who has no idea about datogrid to be able to transform your HTMl, use xsl.
Datagrid is more powerful, much easier to do sorting and paging for example.

Elina
Life is great!!!
Enjoy every moment of it!

I also posted this message at the C# forum as I am programming in that so if this post looks familiar....
I have a project where the user enters a part number. Based on that part number a datagrid will return associated info. The main row will return 1-to-1 items such as part description, drawing location, etc. I plan to use nested datagrids as there will be multiple subparts per part, multiple costs per part etc.
Anyhow, all total I have about 11 tables I need to use. The problem I am facing is that not all parts have a drawing location. When this is blank, the entire row turns up blank.
How do I fix it so that the grid returns any data that is present, and ignores null information?

Now I want to get the values of checkboxes which user selected on post back. but when i try to get the values on post back, it gives me an error like "checkbox list doesnot exist" or "Object reference not set".Please help me  . Following is my code:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
if Not page.ispostback
Dim Reader As SqlDataReader
Dim uamenity_Chklist As CheckBoxList = New CheckBoxList
sqlStatement = "SELECT unitamenity_id,unitAmenity_name FROM UNITAMENITY_MASTER"
cmd.CommandText = sqlStatement
cmd.Connection = conn
Reader = cmd.ExecuteReader()
uamenity_Chklist.ID = "chkUamenity"
uamenity_Chklist.DataSource = Reader
uamenity_Chklist.RepeatColumns = 2
uamenity_Chklist.DataValueField = "unitamenity_id"
uamenity_Chklist.DataTextField = "unitAmenity_name"
uamenity_Chklist.DataBind()
Reader.Close()
Dim CBrow As New HtmlTableRow
UAmenity.Rows.Add(CBrow)
Dim CBCell As New HtmlTableCell
CBrow.Cells.Add(CBCell)
CBCell.Controls.Add(uamenity_Chklist)
