Datagridview Error: At least one of the DataGridView control's columns has no cell te

[Singh Harminder]

I created few datagridview columns and then tried to add them to the datagridview columns collection, but got error : At least one of the DataGridView control's columns has no cell template.

Code:
DataGridView dt = new DataGridView();

DataGridViewColumn dt1 = new DataGridViewColumn();
dt1.Name = "col1";
dt1.HeaderText = "col1";

DataGridViewColumn dt2 = new DataGridViewColumn();
dt2.Name = "col2";
dt2.HeaderText = "col2";

dt1.Tag = "sfs";
dt2.Tag = "wer";

dt.Columns.Add(dt1); >> Error occurs here
dt.Columns.Add(dt2);

Solution:
We need to define the data type of the column specfically that what kind of data it is going to contain


Code:
DataGridView dt = new DataGridView();

DataGridViewTextBoxColumn dt1 = new DataGridViewTextBoxColumn();
dt1.Name = "col1";
dt1.HeaderText = "col1";

DataGridViewTextBoxColumn dt2 = new DataGridViewTextBoxColumn();
dt2.Name = "col2";
dt2.HeaderText = "col2";

dt1.Tag = "sfs";
dt2.Tag = "wer";

dt.Columns.Add(dt1);
dt.Columns.Add(dt2);
