Hi,

I am dynamically binding the Grid view on button click. But the problem is that if I again press on the button the duplicate data displays.

for ex.
button click
abc xzy
1 1
2 1

again button click
button click
abc xzy abc xzy
1 1 1 1
2 1 2 1

Please help.

DataTable GetBatchDetail = new DataTable();
GetBatchDetail = objAdmin.abc(FromDate, Todate, cityid, Type);

foreach (DataColumn col in GetBatchDetail.Columns)
{
           
  BoundField bField = new BoundField();
  bField.DataField = col.ColumnName;
  bField.HeaderText = col.ColumnName;
  GridView1.Columns.Add(bField);
}
GridView1.DataSource = GetBatchDetail;
//Bind the datatable with the GridView.
GridView1.DataBind();

推荐答案

尝试在代码之前添加此代码:

Try to add this code before your code :

//It will clear old DataBindings
dataGridView1.DataBindings.Clear
dataGridView1.Columns.Clear();
