从数据表动态绑定列时，为什么gridview中的列数为0

Question

I have a gridview which show column count 0 when gridview is directly binded to datasource and columns are not defined statically. I am unable to come up with this problem.

I tried this below code:

foreach (GridViewRow row in gv_services.Rows)
{
    if (row.RowType == DataControlRowType.DataRow)
    {
        for (int i = 0; i < gv_services.Columns.Count; i++)
        {
            if (row.Cells[i].Controls[0].GetType() == typeof(CheckBox))
            {
                CheckBox checkBox = row.Cells[i].Controls[0] as CheckBox;

                checkBox.Enabled = true;
                //  checkBox.CheckedChanged += new EventHandler(chck_CheckedChanged);
            }      
        }
    }    
}

If i understood correctly you are trying to loop through gridview rows and enable checkbox based on your conditions

try this code

foreach (GridViewRow row in yourgridview.Rows)
        {
            CheckBox myChk = row.FindControl("myControlName") as CheckBox;
            if (myChk != null)
            {
                myChk.Enabled = true;
            }
        }
