Hi!
I have two gridview that are displaying sql queryes there is two collums and i'm comparing theys two girdview's and i need to display the differences between gridview's on third gridview this gridview has two collums calld 'name' 'amount'. So how i can add rows onthe third girdview on code.
|
|
|
|
|
I would make a DataTable with two columns (name and amount) and put my differences in this table. Then simply set the third gridview's datasource to this new table.

Thanks for the answer, but i have been trying that and not getting it working. here is my code where i'm doing wrong??
DataTable datatable = new DataTable();
DataColumn column;
// Create new DataColumn, set DataType, ColumnName
// and add to DataTable.
column = new DataColumn();
column.DataType = System.Type.GetType("System.String");
column.ColumnName = "Nimike";
datatable.Columns.Add(column);
// Create second column.
column = new DataColumn();
column.DataType = Type.GetType("System.String");
column.ColumnName = "kpl";
datatable.Columns.Add(column);
DataRow dr = datatable.NewRow();
dr["Nimike"] = "Scott";
dr["kpl"] = "25";
datatable.Rows.Add(dr);
dr = datatable.NewRow();
dr["Nimike"] = "Scott";
dr["kpl"] = "25";
datatable.Rows.Add(dr);
dr = datatable.NewRow();
dr["Nimike"] = "Scott";
dr["kpl"] = "25";
datatable.Rows.Add(dr);
dr = datatable.NewRow();
dr["Nimike"] = "Scott";
dr["kpl"] = "25";
datatable.Rows.Add(dr);
gvErot12.DataSource = datatable;
gvErot12.DataBind();
I know that the answer is simple but I cant get it working the gridview is empty but in gvErot12->Rows->Count is 4 but in the gridview is empty.
The code above is only example for the code that I'm using.
Thx

I dont in C# but in VB u need to declare the Datatable as shared.It might be static in C#.

Like the guy who posted before me, I also code in VB. So I'm not sure if this is a problem at all, but in VB you can't declare a column, add it to a table, and then use it to create another column and add it to the table. You have to create two instances of a column and add them separately. The same thing goes with the datarow object.
Where are you putting this code? Is it in the PageLoad event?
I would suggest putting a break point in and actually looking at the datatable to make sure it looks the way you want it to. This will narrow it down to find out if the problem is with setting up the datatable or with actually binding the data to the grid.
Sorry I couldn't be of more help.

Thanks for your help I find the resolution for the problem. I needet to this
gvErot12 = generateBoundField(datatable, gvErot12);
private GridView generateBoundField(DataTable dt,GridView gv)
{
//Iterate through the columns of the datatable to set the data bound field dynamically.
foreach (DataColumn col in dt.Columns)
{
//Declare the bound field and allocate memory for the bound field.
BoundField bfield = new BoundField();
//Initalize the DataField value.
bfield.DataField = col.ColumnName;
//Initialize the HeaderText field value.
bfield.HeaderText = col.ColumnName;
//Add the newly created bound field to the GridView.
gv.Columns.Add(bfield);
}
return gv;
}
this returns the gridview back to the main program and there
gvErot12.DataSource = datatable;
gvErot12.DataBind();
thanks for quideance!!!!!!!

hi this is wat the books says:
It uses the supplied SQL membership provider to manage the user database.
If you want to extend the application so that it tracks additional
data besides the user name, password, and the secret question and
answer, or if you want to use your own database to store the member
information, you can code your own provider. For most applications,
however, the supplied provider should be adequate.
however i would like to connect it to my own sql membership provider anyone know what i should change?
