So now you want to create controls dynamically!

I would suggest you to place a panel in your form and in that panel you can bind your labels.

example:

Label label1 = new Label();
label1.ID = "your id"
label1.CssClass ="your class if available";
label1.Text = "label text"

Then you can add this label to your panel
panel1.Controls.Add(label1);

No yar i am not getting what i want...,

see after my query i am fetching records and displaying like this...,

If TypeOf (myDataSet.Tables(0).Rows(0)(0)) Is DBNull Then
lblid.Text = String.Empty
Else
lblid.Text = myDataSet.Tables(0).Rows(0)(0)
end if

In design time itself if i declare label then fields 0 place also want to show...,
thats y i think to change dynamic control create...,

If TypeOf (myDataSet.Tables(0).Rows(0)(0)) Is DBNull Then
'lblid.Text = String.Empty
Dim dynlabel1 As New Label
dynlabel1.Text = "No Id"
Else
Dim dynlabel1 As New Label
Dim dynlabel2 As New Label
dynlabel1.ID = "lbId"
dynlabel1.Text = "ID" & ":" & myDataSet.Tables(0).Rows(0)(0)

lblid.Text = myDataSet.Tables(0).Rows(0)(0)
Panel1.Controls.Add(dynlabel1)

End If

So each and every if condition i want to create dynamic label?,
No other way is there?,

hi Magh_M,

I am having same condition in my application .. my code is as shown below ..it's in c#..i converted DataTable to DataView .. so it is easy to customize..

for (int i = 0; i < questdv.Count; i++)
{
Label l1 = new Label();
l1.Text = questdv[i][columnname].ToString();

//if u want to check for null value u can use
//if(string.IsNullOrEmpty(questdv[i][columnname].ToString())

Panel1.Controls.Add(li);
}

Hi there,
I have a doubt reg the Datagrid which uses a CheckBox Column.

I have a Webform.In that I have 2 option buttons,1 Datagrid,1 Button.
The 2 option buttons are :

1)Employee_btn(When i select this,Datagrid will be filled with the Employee ID,Employee name along with the CheckBox Column).
2)Department_btn(When i select this,Datagrid will be filled with the Department_name)

1 Button is Submit_Btn

Now my requirement is I need to take the checked Items from the datagrid and store it in a char Array(For example,when I select 2 out of 3 department names I need to store the two department names in a string array.
How to do that??

Kindly help me as soon as possible.I need to finish this with in 3 days.

Thanks in advance.

Are you displaying value on a DataGrid ? If yes on ItemDataBound event check the value. If it is 0 , replace with blank value.

Magi,

If your binding this datatable to a datagrid i guess there is way avoiding zeroes by writing the code in ItemDataBound event
