          //Initalize the DataField value.
          bfield.DataField = col.ColumnName;

          //Initialize the HeaderText field value.
          bfield.HeaderText = col.ColumnName;

          //Add the newly created bound field to the GridView.
          gvAlumni.Columns.Add(bfield);

      //Initialize the DataSource
      gvAlumni.DataSource = dt;

      //Bind the datatable with the GridView.
      gvAlumni.DataBind();
          }
          catch (Exception ex)
          {
              throw (ex);
          }

      protected void btnSave_Click(object sender, EventArgs e)
      {
          load_dynamic_grid();
          txtnm.Text = "";
      }

推荐答案

为gridview设置AutoGenerateColumns =false。

SET AutoGenerateColumns = "false" for gridview.

使用这个



DataTable dts = new DataTable（）;

//添加colums

dts.Columns.Add（id，typeof（System.String））;

dts.Columns.Add（Property，typeof（System.String））;

dts.Columns.Add（Values，typeof（System.String））;

dts.Columns.Add（Names，typeof（System.String））;



//添加行

DataRow _mk = dts.NewRow（）;

_mk [id] = 1;

_mk [Property] =xxx;

_mk [Values] =yyy;

_mk [姓名] =zzz;

dts.Rows.Add（_mk）;



可能会有帮助

use this

DataTable dts = new DataTable();
//for add colums
dts.Columns.Add("id", typeof(System.String));
dts.Columns.Add("Property", typeof(System.String));
dts.Columns.Add("Values", typeof(System.String));
dts.Columns.Add("Names", typeof(System.String));

//for add rows
DataRow _mk = dts.NewRow();
_mk["id"] = "1";
_mk["Property"] = "xxx";
_mk["Values"] = "yyy";
_mk["Names"] = "zzz";
dts.Rows.Add(_mk);

may b this will help

private DataTable CreateDynamicTable（）

{

DataTabl e dt = new DataTable（mytable）;

string colCount = TextBox1.Text;

string rowCount = TextBox2.Text;

for （int i = 0;我< Convert.ToInt32（rowCount时）; i ++）

{

DataRow dr = dt.NewRow（）;

dt.Rows.Add（dr）;

}

for（int i = 0; i< Convert.ToInt32（colCount）; i ++）

{

dt。 Columns.Add（Col+ i，typeof（string））;

}

返回dt;

}





将返回的数据表绑定到网格视图

private DataTable CreateDynamicTable()
{
DataTable dt = new DataTable("mytable");
string colCount= TextBox1.Text;
string rowCount = TextBox2.Text;
for (int i = 0; i < Convert.ToInt32(rowCount); i++)
{
DataRow dr = dt.NewRow();
dt.Rows.Add(dr);
}
for (int i = 0; i < Convert.ToInt32(colCount); i++)
{
dt.Columns.Add("Col" + i, typeof(string));
}
return dt;
}


Bind the datatable returned to a grid view
