Solution 1

Why do you need for loop?

Try this solution, i have just removed for loop.

C#

string xxxx = "select title from document";
ad1 = new SqlDataAdapter(xxxx, c.getcon());
ds1 = new DataSet();
ad1.Fill(ds1);

if (ds1.Tables[0].Rows.Count != 0)
{
GridView1.DataSource = ds1;
GridView1.DataBind();
}

Make the for loop for the where condition only when you will get the desired solution.

C#

string xxxx;
for (int k = 0; k < intArray.Length; k++)
{
    xxxx += "'" + intArray[k] + "'," ;
}

xxxx = xxxx.Substring(0, xxxx.Length - 1);
SqlCommand cmd = new SqlCommand("select title from document where id in " + xxxx + ")", cn);
ad1 = new SqlDataAdapter(xxxx, c.getcon());
ds1 = new DataSet();
ad1.Fill(ds1);

if (ds1.Tables[0].Rows.Count != 0)
{
GridView1.DataSource = ds1;
GridView1.DataBind();
}

This is not quite the correct approach.
You are actually overriding the gridview source in every iteration of the loop.

Try something similar to this

string xxxx = "select title from document where id in('";
for (int k = 0; k < intArray.Length; k++)
{
xxxx+=intArray[k]+"',"
}
xxxx=xxxx.SubString(0,xxxx.length-1) + ")";
 
ad1 = new SqlDataAdapter(xxxx, c.getcon());
ds1 = new DataSet();
ad1.Fill(ds1);
 
if (ds.Tables[0].Rows.Count != 0)
{
GridView1.DataSource = ds1;
GridView1.DataBind();
}
