i have dataset, which has 7 columns,
i have a datagrid, binded to above dataset,i have a boolean column,whose columnstyle is datagridviewcheckbox style, i want to set it to
datagridviewtextboxcolumn style,

so that when boolean values are displayed in datagrid, instead of checkbox,i want true/false text to be written as column values.

DataSet ds = daoDistrict.FillDistrictGrid(Convert.ToInt32(cbStateName.SelectedValue));
dgDistrict.DataSource = ds.Tables[0];                        

DataGridViewTextBoxColumn txtBxCol = new DataGridViewTextBoxColumn();
            DataGridViewColumn tempCol = (DataGridViewColumn)dgDistrict.Columns[6];
            txtBxCol = (DataGridViewTextBoxColumn)tempCol;            
            txtBxCol.Name = "IsActive";
            txtBxCol.DataPropertyName = "IsActive";
            txtBxCol.HeaderText = "Is--Active";
            DataGridView dgv = txtBxCol.DataGridView;            
            bool val = txtBxCol.Displayed;
            int ind = txtBxCol.DisplayIndex;
            bool isDat = txtBxCol.IsDataBound;
            txtBxCol.ValueType = txtBxCol.GetType();

above code throws cast exception, unable to cast DGVCheckbxcol to DGVtextbxcol

thanks in advance

unable to cast DGVCheckbxcol to DGVtextbxcol

this can be never casted, DataGridViewTextBoxColumn is deferent from DataGridViewCheckBoxColumn

try

DataGridViewCheckBoxColumn txtBxCol = new DataGridViewCheckBoxColumn();
            DataGridViewColumn tempCol = (DataGridViewColumn)dgDistrict.Columns[6];
            txtBxCol = (DataGridViewCheckBoxColumn)tempCol;
