推荐答案

//从子网格页脚添加记录的代码

受保护的void gvChild_RowCommand(object sender，GridViewCommandEventArgs e)
{
DataTable dt = ViewState ["dt"] as DataTable;
DataTable dtCity = new DataTable();
dtCity = ViewState ["ddl"]作为DataTable;
GridView gvChild =(GridView)((LinkBut​​ton)e.CommandSource).NamingContainer.Parent.Parent;
如果(e.CommandName =="AddChild")
{

TextBox txtName =(TextBox)gvChild.FooterRow.FindControl("txtName");
DropDownList ddlCity =(DropDownList)gvChild.FooterRow.FindControl("ddlCity");
dt.Rows.Add(txtName.Text，ddlCity.SelectedValue);
ViewState ["dt"] = dt;
gvChild.DataSource = dt;
gvChild.DataBind();
ddlCity.DataSource = dtCity;//如果您的子网格页脚中有下拉菜单
ddlCity.DataValueField =城市";
ddlCity.DataTextField =城市";
ddlCity.DataBind();

}
}

// Code for adding record from child grid footer

protected void gvChild_RowCommand(object sender, GridViewCommandEventArgs e)
{
DataTable dt = ViewState["dt"] as DataTable;
DataTable dtCity = new DataTable();
dtCity = ViewState["ddl"] as DataTable;
GridView gvChild = (GridView)((LinkButton)e.CommandSource).NamingContainer.Parent.Parent;
if (e.CommandName == "AddChild")
{

TextBox txtName = (TextBox)gvChild.FooterRow.FindControl("txtName");
DropDownList ddlCity = (DropDownList)gvChild.FooterRow.FindControl("ddlCity");
dt.Rows.Add(txtName.Text, ddlCity.SelectedValue);
ViewState["dt"] = dt;
gvChild.DataSource = dt;
gvChild.DataBind();
ddlCity.DataSource = dtCity;// If u have dropdown in your child grid footer
ddlCity.DataValueField = "City";
ddlCity.DataTextField = "City";
ddlCity.DataBind();

}
}

U可以对子网格的rowcommand事件执行操作.在rowcommand事件中检查命令名称并执行操作.

U can do on rowcommand event of child grid .in rowcommand event check command name and perform operation .
