DataSet DataTable Problem...

Question

0.00/5 (No votes)

See more:

I have a DataSet that has only one row, and I'm in the middle of a gridView. Now I have to bind a DataList with some of the DataSet Rows that will be generated from the gridView Rows.

I have used a DataTable like dis

C#

 DataTable dt = new DataTable();
foreach (GridViewRow row in GridView1.Rows)
{
// Some Lines Of Code
DataRow dr = ds.Tables[0].Rows[0];
dt.ImportRow(dr);
}
//After the foreach loop

DataSet ddss;
ddss.Tables[0] = dt;  //IS THIS RIGHT or IS THERE ANY OTHER WAY...???

DataList1.DataSource=dt;
DataList1.DataBind();

I don't know whether I explained it right. Just do le'me know.

>>>><<<<<<SORRYY GUYS>>>>>><<<<<<

Actually I missed to mention that the actual error I was getting in the

"Can't Find The SPECIFIC Columns Name"

And To resolve that I used ...

C#

dt.Columns.Add("abc", Type.GetType("System.String"));
dt.Columns.Add("def", Type.GetType("System.String"));
dt.Columns.Add("ghi", Type.GetType("System.String"));
// AND SO ON

Thanks to everybody for help...

Solution 1

Try

C#

ddss.Tables.Add(dt);

Using "Add" will work, you just don't have an actual dataset created yet.

Change

C#

DataSet ddss;

to

C#

DataSet ddss = new DataSet();

Without setting ddss to a new dataset (or one that's previously created), there's nothing to add the datatable to.

Didn't Work ... Object reference not set to an instance of an object.

You can try this.

DataTable dt = new DataTable();
dt.Columns.Add("abc", Type.GetType("System.String"));
dt.Columns.Add("def", Type.GetType("System.String"));
dt.Columns.Add("ghi", Type.GetType("System.String"));

foreach (GridViewRow row in GridView1.Rows)
{
DataRow dr = ds.Tables[0].Rows[0];
dt.ImportRow(dr);
}

DataSet ddss = new DataSet();
ddss.Tables.Add(dt);

DataList1.DataSource = dt;
DataList1.DataBind();
