推荐答案
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox chk = new CheckBox();
chk.EnableViewState = true;
chk.Enabled = true;
chk.ID = "chkb";
e.Row.Cells[1].Controls.Add(chk);
}
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var chk = (CheckBox)e.Row.FindControl("chkb");
// databind it here according to the DataSource in e.Row.DataItem
}
}
从网格视图中获取值时，您已遍历网格视图的每一行，因为
While getting the value from grid view you have loop through each row of Grid view as
foreach(GridViewRow row in GridView2.Rows)
{
for(int i = 0; i < GridView2.Columns.Count; i++)
{
string header = GridView2.Columns[i].HeaderText;
CheckBox chkp=(Checkbox)GridView1.Rows[e.RowIndex].Cells[1].FindControl("chkp");
CheckBox chkg=(Checkbox)GridView1.Rows[e.RowIndex].Cells[2].FindControl("chkg");
//Get the .checked values of chkp and chkg show it as you desire
string Ans= chkp.checked==True?"CheckP":chkg.checked==True?"CheckG":"No Answer"
}
}
代码可能无法编译，因为未经过测试。
Code might not compile as its not tested.
试试这个
try this
<head>
<script src="jquery.js"></script>
<script>
function GridSelectAllColumn(obj, val) {
var
